Preferably, the edge of the spiral blade is coated with a rubber layer, and the edge of the spiral blade is attached to the inner wall of the treatment chamber.
Preferably, an end plate is mounted to the top end of the process chamber by bolts.
Preferably, the support column is inserted into the processing chamber, and the bottom end of the support column is propped against the bottom end of the processing chamber.
Preferably, the adsorption blade comprises a connection ring and a frame, and an activated carbon plate for adsorbing fluoride is installed inside the frame.
Compared with the prior art, the utility model has the following beneficial effects:
this exhaust treatment device, become the microparticle through atomizer atomizing sodium hydroxide solution, when waste gas through spray room, can carry a large amount of sodium hydroxide microparticle, make sodium hydroxide microparticle evenly mix in waste gas, adsorb fluoride in the waste gas, afterwards waste gas gets into in the treatment room, and make ascending helical motion along helical blade, under centrifugal force, the microparticle in the waste gas can be close to the treatment room inner wall and adhere to, and liquid particle in the waste gas and helical blade contact also can adhere to and condense on it, reduce the liquid particle in the waste gas, afterwards the waste gas passes through the fluoride in the further absorption waste gas of adsorption blade, thereby clear away most fluoride in the waste gas.
