Calcium Hydroxide Production Line

The calcium hydroxide production line uses blades and mixing methods made of special materials to make the quicklime and water mix uniformly and fully react, and the hydroxide production line equipment can adopt biaxial mixing, with mixing, crushing, agglomeration, and self-cleaning. Function, its design can play a role in breaking the agglomeration produced in the reaction process.

Gaifeng calcium hydroxide production line equipment is designed and manufactured in strict accordance with ISO9001 international quality management system certification, ISO14001 international environmental management system certification, and ISO18001 employee health management system certification indicators. The company has a strong technical force and a number of technical patents. In the process of development, it continues to communicate and cooperate with related disciplines and research institutions and universities to continuously develop, optimize and design new products.


Advantages of Calcium Hydroxide Production Line

  • Increase the thermal conversion catalytic system. Use its own heat energy to heat the digestion water, accelerate the digestion reaction, recover part of the water vapor, and reduce the water vapor emission.

  • The F series integral reducer is adopted, and the main shaft is a through-shaft design. Avoid unbalanced equipment operation caused by coaxiality error.

  • The blades of the digester are arranged out of order and staggered. Avoid problems such as torque fluctuations caused by uneven materials.

  • The digestion dust collector adopts the integrated design of digestion and dust removal. The structure is more compact, and the dust-removing powder (superfine powder) is directly discharged into the third-stage digestion and then enters the powder selection equipment.

  • Screw conveyor adopts variable pitch conveying. Reduce the conveying resistance and reduce the wear of spiral blades.

  • The internal blades of the screw conveyor are extruded and formed by NM400 wear-resistant steel plate to ensure the service life.

  • The inside of the digester adopts NM400 replaceable stirring gear design to reduce equipment wear.

  • The stirring gear of the digester adopts the plow-type stirring gear, which reduces the power of the equipment and reduces the impact of the equipment starting current.

  • Digest and install an adaptive fan adjustment system for dust removal (company invention patent). When the air volume to be handled changes (the amount of steam increases or decreases, the opening and closing of the observation port, the opening and closing of the dust collecting hood, the increase in pipeline loss design, etc.), the fan is automatically adjusted to reduce power consumption.

  • The lightweight powder separator adopts the design of circulating air negative pressure to ensure the energy saving of circulating air and avoid accidental dust leakage.

  • The light-weight separator is lined with NM400 wear-resistant steel plate. The air inlet of the finished product collector adopts the ceramic welting process to prevent the internal abrasion of the equipment.

Tips:

⑴The raw materials are measured from the via the and then enter the , and then fall into the through the .

⑵The raw materials are mixed with water in the first digester of the ashing machine, and the pre-digestion reaction is carried out through stirring, and then sent to the second digester.

(3) The pre-digested materials are digested again in the and sent to the .

⑷The semi-digested raw materials are fully stirred and reacted by the . Using the heat generated by itself, the excess water in the material is evaporated, and the mixture of calcium hydroxide powder and impurities (non-reactive substances such as raw burnt and quartz) that is lower than the dew point (75°C) is discharged.

⑸The mixed material is discharged from the at the lower end of the , and is sent to the inlet of the powder concentrator through the lifting equipment.

⑹There is a special dust collector at the upper end of the that works under high alkali and humid conditions. This dust collector releases and discharges the steam pressure generated during the exothermic reaction of digestion and sends it to the heat exchange System> to form a negative pressure inside the entire digestion unit to avoid leakage of steam and dust. The filtered wet powder is directly returned to the and mixed with other materials.

⑺The discharged hot air containing water vapor is exchanged by the , which partially reduces the water vapor, heats the equipment water, and uses hot water as production water into the .

can adjust the fineness on-line, selects the powder whose fineness is higher than the set fineness, and sends it to the through four separate The conveying finally reaches the finished product tank, and the powder with the fineness lower than the set fineness is discharged, and sent to the slag discharge screw via the and finally arrives at the ash storage.

is designed for self-circulating air, and there is no gas emission during use. It is equipped with a small , which pumps the entire into negative pressure to achieve the goal of no dust and leakage.
