What are the production specifications of calcium hydroxide production line

An important application of calcium hydroxide is as a flocculant for water and sewage treatment. It forms fluffy charged solids that help remove smaller particles from the water, resulting in a more transparent product. This application benefits from the low cost and low toxicity of calcium hydroxide. It’s also used in freshwater treatment to raise the pH of the water so that the pipes don’t corrode when the base water is acidic because it’s self-regulating and doesn’t raise the pH too much.

Therefore, we should correctly select the production specifications of calcium hydroxide production line when purchasing equipment, otherwise it will affect the working efficiency of the equipment to a certain extent. So what are the production specifications of calcium hydroxide production line?

What are the precautions when feeding calcium hydroxide equipment?

Calcium hydroxide equipment is mainly used to produce calcium hydroxide and other chemical products, and almost the entire production is carried out on this equipment. When feeding, you must pay attention to the relevant requirements, and there are also many things to pay attention to.

Precautions when feeding calcium hydroxide equipment

1. The calcium hydroxide equipment cannot meet the classification requirements of micropowder in the cement grinding system, mainly because the specific gravity of the micropowder is much smaller than that of the cement, so the equipment has a weak ability to identify the micropowder.

2. When entering the negative pressure operation, the grinding material is fed from the inlet of the calcium hydroxide equipment of the distributor, and meets the vortex airflow entering the primary air outlet. After being fully dispersed by the suspension dispersing mechanism, the fine powder enters the grading area through the secondary air outlet in the airflow. The resulting horizontal vortex field is graded.

calcium hydroxide equipment

3. The discharge temperature is controlled at about 45 degrees Celsius, and the water content of the discharge is controlled at about 1%. In this way, the agglomeration of finished products is prevented, and the efficiency of powder selection and the waste of slag discharge are improved.

4. The fine powder enters the rotating cage, and the negative pressure air is pumped into the subsequent dust collector from the fine powder outlet, and the finished product is collected by the dust collector. The coarse powder falls into the cone, is discharged through the coarse powder outlet, and returns to the mill for grinding again.

5. Add the raw material quicklime of the loader into the silo, evenly add it to the jaw crusher with a vibrating feeder, and crush it to about 30-50 mm. The dust generated during the crushing process of the equipment is passed by the induced draft fan through the jaw crusher and hydrogen peroxide. The dust cover of the calcium equipment is introduced into the pulse bag filter outside the workshop, which should be cleaned once a week.

6. Rigid inspection is carried out by electronic means, and laboratory personnel carry out sampling per unit time to ensure the stability of product quality and avoid quality problems caused by deviation of raw materials.

7. The equipment maintenance worker will check the operation cycle of each part, find and solve the problem in time, avoid the equipment running with faults, and improve the service life of the equipment.

8. The equipment should be remotely switched on and off in various parts of the equipment production area to deal with emergencies and avoid economic losses of personnel.

9. Rigid assessment by electronic means to avoid oil-free work and accidental wear in the lubrication cycle of each operating part.

The above are the precautions when feeding calcium hydroxide equipment. In fact, when feeding calcium hydroxide equipment, you must pay attention to learning to adjust properly, because the operations that need to be done will be different. It is hoped that in the future, operators can pay attention to some of the above-mentioned details, which will effectively increase their production.

What are the applications of calcium hydroxide in waste incineration

Nowadays, life is constantly progressing and developing. Of course, it also produces a lot of negative things. There are more and more garbage around us. If we do not deal with it in time, we will soon be buried by garbage. Generally speaking, garbage incineration is still a Now we use the common way of dealing with garbage. In order to prevent the continuous infestation of harmful substances, we can add calcium hydroxide to it.

I believe that friends who see it here will be confused and wonder if they are wrong. Yes, you read that right! In order to let everyone know how widely used calcium hydroxide is, the following calcium hydroxide production line manufacturers will introduce to you the applications of calcium hydroxide in waste incineration.

GFEX Case

Application of calcium hydroxide in waste incineration:

1. Garbage incineration is a method used by most cities to dispose of garbage. Therefore, incinerators have been built in various places. After the garbage is treated by incineration, the amount of garbage can be reduced, and land use can also be saved. Such a process can also eliminate a large number of pathogens and convert toxic and harmful substances into non-toxic and harmful substances.

2. For the flue gas generated during the combustion process, the flue gas temperature drops sharply from more than 400 degrees Celsius to about 120 degrees Celsius. After that, the activated carbon and calcium hydroxide are deacidified in the reaction tower, and the activated carbon adsorbs harmful gases such as dioxins; The flue gas enters the dust collector, is adsorbed to remove particulate matter, heavy metals, etc. in the flue gas, and then is discharged into the atmosphere through the chimney.

GFTX tower case

3. For flue gas treatment, calcium hydroxide (Ca(OH)2) can be made into a slurry, and then the slurry can be atomized into droplets by a high-speed rotating atomizer, and sprayed into the flue gas collection tower. The average diameter of the incoming droplets is 150 microns. In the process of flue gas treatment, the heat contained in it will be transferred to the mist droplets, which will continuously dry and eventually become powder. The powder components include calcium chloride, calcium sulfate, calcium fluoride and incompletely reacted calcium hydroxide, most of which are separated from the flue gas in the tower and discharged from the cone outlet, and a small part enters the cloth belt with the flue gas for dust removal. device collection. Using this method can well deal with the problem of flue gas pollution in the process of waste-to-energy generation.

It can be said that calcium hydroxide is one of the necessary items to deal with waste incineration pollution. Through the treatment of harmful flue gas, the pollution to the atmospheric environment can be reduced. I believe that through this introduction, many friends will be familiar with the use of calcium hydroxide in waste incineration. We still need to know more about important matters such as people’s livelihood. For the health of our living environment, we need Take precautions against issues like garbage disposal.

What are the differences between calcium hydroxide equipment and traditional production processes?

In recent years, with the continuous development of my country’s calcium hydroxide market, the technical indicators of calcium hydroxide products are also constantly improving. The traditional calcium hydroxide production process and the inability to meet market demand and technical indicators have been gradually replaced by calcium hydroxide equipment. Everyone has a lot of doubts about calcium hydroxide equipment. Many people are curious about the difference between calcium hydroxide equipment and traditional production processes? Next, I will introduce you to it.

The difference between calcium hydroxide equipment and traditional production process

GFEX Case

1. Production process

The calcium hydroxide that can be mechanized and produced on a large scale using calcium hydroxide equipment has a much higher product quality than hand-produced products. At the same time, the equipment also realizes automatic control and online real-time monitoring. The entire production line only needs 2 to 3 employees, which saves human resources.

The traditional production process is mainly manual, and the product quality is not very good. It is mainly used in low-end markets such as sewage treatment, ash calcium, and putty powder.

2. Calcium hydroxide production

The production of calcium hydroxide equipment can realize large-scale production of calcium hydroxide. The output of a single machine ranges from 3T/h to 20T/h, and different schemes can be completed according to the requirements of users.

The traditional production process is inefficient, and each person does not exceed 1 ton of finished calcium hydroxide during the day. Such production capacity cannot meet the large demand for calcium hydroxide in various industries such as power plant desulfurization, fine chemical industry, pharmaceutical food, petroleum, and paper making.

GFTX tower case

3. Quality aspects of calcium hydroxide

The calcium hydroxide equipment can control the discharge temperature at about 45 °C, and control the water content of the discharge at about 1%. Prevent product agglomeration, improve powder selection efficiency and slag waste.

The traditional production process relies on the experience of the workers to control the production process, and the product has a high water content and is easy to agglomerate.

4. Environmental protection

The pollution points in the production process of the calcium hydroxide equipment are all completed by the pulse dust collector, and the dust removal rate reaches 99.5%, which will not pollute the workshop and play a role in protecting the environment.

Using traditional production technology, due to manual production, a large amount of high-temperature steam and dust generated during the digestion process are diffused everywhere, and the dust pollution radius is at least 1,000 meters. Forests and crops within the contamination range are prone to disputes.

5. Dealing with emergencies

All parts of the calcium hydroxide equipment are equipped with remote control switches, which can deal with emergencies and avoid personnel and financial losses.

In traditional production plants, manual operations are required by personnel. If there is an emergency, it is easy to fail to respond in time.

Regarding the difference between calcium hydroxide equipment and traditional production processes, the above is the relevant introduction brought to us by calcium hydroxide equipment manufacturers, hoping to help you.

How to adjust the fineness of calcium hydroxide equipment?

Users who purchase calcium hydroxide equipment production lines usually consult in detail about what standard the calcium hydroxide produced by calcium hydroxide equipment can meet, and purchase corresponding supporting production lines according to their own goals.

At present, the calcium hydroxide powder produced by domestic calcium hydroxide equipment can reach industrial grade use, the fineness is generally 200-400 mesh, and the content is generally 65%-93%. construction and other industries.

The fineness of calcium hydroxide equipment can reach about 325 mesh, and it can produce 6-20 tons of finished calcium hydroxide per hour. If it is produced in 24 hours, it can produce up to 480 tons of calcium hydroxide powder a day, which can meet the high standard requirements of users.

How to ensure the powder fineness of calcium hydroxide equipment?

For the performance of calcium hydroxide equipment, powder fineness is undoubtedly a very important measure. Users all hope that the purchased equipment can achieve stable powder fineness and ensure powder quality. From the following two aspects to ensure that users buy Equipment to the desired effect and standard.

1. The matching powder selection device is very important. Its main function is to classify and screen the powder processed by the calcium hydroxide equipment, and select qualified finished products. Therefore, for the calcium hydroxide production line, choose the selection that is suitable for your own production line requirements. The size of the powder machine becomes very important.

Calcium hydroxide production line manufacturers will design the best supporting facilities according to the needs of users and comprehensive factors.

2. In the calcium hydroxide production process, the importance of the lime digester cannot be ignored. The calcium hydroxide production line must continuously combine advanced technology to innovate and upgrade the performance of the lime digestion process, so that the raw materials can be quickly and fully reacted inside the machine. achieve the desired granularity.

How to adjust the fineness of calcium hydroxide grinding equipment?

In the production of calcium hydroxide mill, its own processing fineness requirements are mainly adjusted within a certain range according to user needs. Some customers consulted in the production process, the fineness of calcium hydroxide grinding equipment is not well controlled, and the particle size often does not meet the standard. So what are the methods to improve the processing fineness of calcium hydroxide mill? Let’s find out together.

When the calcium hydroxide mill is in use, its main motor adopts frequency conversion speed regulation, so that the spindle speed can be greatly adjusted, thereby changing the centrifugal force of the grinding roller pressing against the grinding ring and changing the grinding effect. Mainly to further increase the output after grinding the coarse powder, the power of the main engine and the blower motor is appropriately increased.

The swing position of the grinding roller of the calcium hydroxide mill is effectively limited, so that a gap is formed between the grinding roller and the grinding ring during operation, and the gap can be adjusted at will, so that the grinding intensity can be greatly adjusted and the particle size can be controlled. At the same time, for the adjustment of the air supply system, the internal air speed and air volume can be adjusted, so that the air selection particle size is proportional to the flow rate of the wind wheel.

How to deal with dust when calcium hydroxide powder is selected?

Calcium hydroxide powder selection is to make the extracted calcium hydroxide mesh more pure. There are many kinds of powder separators, such as centrifugal, three-separation, fly ash and other different types. Qualified powder is selected.

In the process of calcium hydroxide production, even if it is produced by professional calcium hydroxide production line equipment, it is almost inevitable to mix impurities. In order to improve the quality and purity of calcium hydroxide powder, it is necessary to select qualified powders. For this qualification, in addition to requiring purity, the fineness of the powder should also be distinguished.

Small calcium hydroxide powder also has many parameters. It is based on these parameters that people keep thinking about the method of powder selection and design a powder separator. For example, according to the quality and density of the powder, under a certain wind speed, the powder can be divided into two piles with a cyclone separator. Obviously, the pile is needed, and the pile is the so-called impurity.

For the powder separator, the simpler the structure, the better, and the overly complicated powder selection channel is not conducive to the discharge of the selected powder from the powder selection device.

Due to the centrifugal force of the calcium hydroxide powder separator during the powder selection process, it is inevitable that dust will occur. When it comes to dust removal, the first thing that comes to mind is the pulse bag filter.

calcium hydroxide

Pulse dust removal adopts pulse bag type dust removal technology, which overcomes the shortcomings of conventional pulse dust collectors and sub-chamber back-flushing dust collectors. The land area is small, the operation is stable and reliable, and the economy is good. And the falling powder can be recycled and reused, which is a link to reduce the cost of producing calcium hydroxide powder, which overcomes the problem of re-pollution of water dust removal. Any conveying device falls directly into the digester and enters the powder selection system.

Moreover, the clean hot air after dust removal enters the vertical heat conversion device to heat and digest water. In this way, the equipment is protected, the later maintenance is simple, and the impact of dust emission pollution on the surrounding environment can be greatly improved in terms of environmental protection, and the working environment of workers is also greatly improved.

In addition to pulse bag dust removal, there is also a water dust removal method. The water precipitator is a device that makes the dust-containing gas in close contact with water, and uses the inertial collision of water droplets and particles and other effects to capture or increase the particles. The manufacturing cost of the water precipitator is relatively low. However, it is an ideal dust removal method for dust with moisture, stickiness and irritating odor generated in the chemical industry, painting, glaze, pigment and other industries.

In comparison, water dust removal is an ideal dust removal method in the calcium hydroxide powder selection process. How to deal with calcium hydroxide after dust removal?

1. Powdered products are used in bleaching, hydrometallurgy, sewage treatment, sugar refining, papermaking, paint, glass production, food industry, etc. In organic chemistry, calcium hydroxide is widely used as a strong base.

2. Paste calcium hydroxide is used for building materials, protecting tree trunks and painting walls.

3. Liquid calcium hydroxide reacts with carbon dioxide to produce calcium carbonate, and liquid lime milk (calcium hydroxide particles suspended in water) can also be used for water treatment, dry flue gas purification, etc.

The energy saving way in calcium hydroxide production is mainly reflected in the selection of digestion equipment. The trough type drying machine and the wet drying machine are ideal equipment, which can be digested with cold water to keep it in a boiling state, so that the product quality is excellent and the energy consumption is low.

The environmental treatment in the production of calcium hydroxide is mainly alkaline dust treatment. First, a closed production line should be selected. Material conveying, feeding, dividing, and packaging equipment should be closed for operation to prevent the overflow of alkaline dust. The digestion steam should be dry. , Wet dust removal to recover steam and dust; crushing and grinding should be carried out under airtight or slightly negative pressure to prevent dust leakage.

Summary of structure and characteristics of lime digester in calcium hydroxide equipment

1. The equipment has its own independent and reasonable dust removal system, so there is no pollution, and the equipment has the characteristics of compact structure:

2. A set of screw feeders are designed at the feed port of the digester to prevent the backflow of steam and dust generated during the digestion process, so that the formed steam and dust can be concentrated to the dust outlet and enter the dust removal equipment to reduce corrosion and damage to surrounding equipment. damage, provide an excellent working environment. At the same time, the utilization rate of quicklime is also improved. This equipment adopts the cover type water adding device, the water adding amount is more uniform, and the quicklime is digested more thoroughly.

3. The equipment adopts double-helix digestion, so it has good digestion effect, uniform feeding, no spraying, and no blocking. It adopts the form of double-shaft stirring, which has multiple functions and effects such as stirring, crushing agglomeration and self-cleaning. Its unique blade and stirring method make the quicklime and water mix evenly and react fully; it can break the agglomeration produced in the reaction process.

4. The equipment has a special outlet for steam and dust discharge, which can be discharged to a special dust removal pipe through a connecting pipe, which can well handle the dust steam and harmful gas generated during the digestion process of quicklime. After use, the waste dust quicklime can be reused , There is no dust pollution in the on-site environment, so that the quicklime digester can reasonably add the required water to achieve the effect of fully digesting the quicklime.

GFEX Case

5. The biaxial blades are made of high-manganese wear-resistant materials, and the heat-treated high-strength wear-resistant alloy materials have the function of self-cleaning bonding materials; effectively avoiding poor discharge and blade wear caused by bonding lime Even the occurrence of problems such as broken shafts prolongs the service life of the equipment.

6. This type of biaxial quicklime digester can be improved in relevant dimensions according to the requirements of the enterprise, and can also be automatically equipped according to the requirements of the enterprise.

7. The blade of the screw shaft is inlaid with cemented carbide, so it has the characteristics of long service life, and the service life is one year with the advantage of equipment.

The above is the summary of the structure and characteristics of the lime digester for calcium hydroxide equipment. Through the above introduction, it is not difficult to know that the main feature of the lime digester (ash machine) is that when the spray device feeds a certain amount of water to the mixing tank After the quicklime is sprayed with water, through the rotation of the specially designed wear-resistant stirring blade, the quicklime is vigorously stirred in the stirring tank and gradually dissolved, digested, slaked and homogenized. The stirring blade also pushes the digested slaked lime powder forward. sports. The components of the damping plate and the limit plate in the stirring tank ensure the digestion time of the quicklime, so that the quicklime is completely digested.
