The desulfurization system adopts MSGF dry desulfurization process, fixed bed structure, the bed is covered with desulfurizer, the flue gas enters the bed from the bottom, and the air distribution is uniform through the porous and ventilated plate in the lower part, the flue gas passes through the desulfurizer material layer, and is catalyzed Convert SO2 into SO2, and be reacted and solidified into calcium sulfate solid (CaSO4). In the reactor, due to the presence of bed material, the desulfurizer can spread with a larger surface area, remove SO2 in the flue gas, and The dust in the flue gas is intercepted and adsorbed to purify the flue gas. The by-products generated in the reactor are regularly replaced as the desulfurization and denitrification efficiency decreases. Its main component is CaSO4, which is common solid waste and can be recycled as building materials.
The upper part of the device is the desulfurization agent inlet, and the lower part is the desulfurization agent discharge port. After the device has been running for a period of time, the desulfurizer in the lower part that is in contact with the flue gas will gradually become invalid, and the desulfurization efficiency will decrease. At this time, the discharge port can be opened and will fail. Part of the desulfurization agent is removed, and fresh desulfurization agent is installed on the upper part of the device to ensure desulfurization efficiency. The desulfurization effect can be adjusted according to the requirements of the contact time, and can achieve more than 80% removal. It is not sensitive to some short-term fluctuations in flue gas conditions, and is not very sensitive to flue gas temperature. It is suitable for almost all flue gas conditions.
