　　On the desulfurization and denitrification project, a rigid impeller feeder is used, and high-temperature purified ash is purified in the carbide purification filter, DN400.2.2KW， Processing capacity ≥ 2t/h, 0.1MPa, ≥ 230 ℃; DN600.4KW， Processing capacity ≥ 6t/h, 0.1MPa, ≥ 500 ℃. A rigid impeller feeder (also known as a rigid dividing wheel unloader, rotary feeder, etc.) is a quantitative feeding and air locking device used for conveying high-temperature materials, hard materials, block materials, and dry powder materials, with excellent load-bearing capacity.

　　Desulfurization: Removing sulfur dioxide from flue gas to prevent the formation of acid rain.

　　Denitrification: Removing nitrogen oxides from flue gas and reducing air pollution.

　　Main applications: flue gas treatment of coal-fired boilers in thermal power plants, steel plants, cement plants, etc.

　　Common techniques: limestone gypsum method (desulfurization), SCR/SNCR catalytic reduction method (denitrification). ‌‌

　　Function of rigid impeller feeder:

　　Realize uniform and continuous quantitative feeding: It uses a rotating impeller to uniformly and continuously feed powdered or small particle materials from the upper silo to the next process equipment. By selecting a speed regulating motor, the feeding amount can also be adjusted as needed.

　　Provide reliable air locking and sealing: isolate the pressure difference between the upper and lower parts in dust removal or pneumatic conveying systems, prevent air flow collusion, and maintain stable negative/positive pressure in the system.

　　Unloading and discharging: As a bottom device of the dust collector ash hopper, it efficiently discharges collected dust or particles, suppressing secondary dust and leakage. ‌‌
