Biological treatment device for organic waste gas

Abstract

The invention discloses a biological treatment device for organic waste gas. The invention relates to the technical field of water spray absorbers. According to the technical scheme, the device comprises a water spraying absorption tower, wherein the water spraying absorption tower comprises a tower body, a filler box fixed at the top of the tower body, a plurality of nozzles fixed on the bottom surface of the filler box, a first fixed rod fixed on the inner circumferential surface of the tower body, a rotating disc rotationally mounted at the bottom of the first fixed rod, a plurality of strip-shaped blades evenly distributed on the outer circumferential face of the rotating disc in the circumferential direction of the rotating disc, a second fixing rod fixed to the inner circumferentialface of the tower body, a first motor fixed to the top of the second fixing rod, and a connecting mechanism arranged between the first motor and the rotating disc and used for connecting the output end of the first motor with the rotating disc. The problem that absorption liquid cannot be in full contact with organic waste gas is solved, and the effect of improving the contact efficiency of the absorption liquid and the organic waste gas is achieved.

Description

technical field [0001] The invention relates to the technical field of water spray absorption towers, more specifically, it relates to a biological treatment device for organic waste gas. Background technique [0002] At present, organic waste gas can only be discharged after biological treatment through water spray absorption, UV photolysis and biological trickling filtration. [0003] The prior art can refer to the Chinese invention patent whose authorized announcement number is CN208959634U, which discloses a waste gas biological treatment device, including a water spray absorption tower, UV photolysis equipment and a biological trickling filter tower; the water spray absorption tower is used to convert the waste gas The gaseous pollutants are transferred to the absorption liquid, so that the gaseous pollutants exist in the absorption liquid in the form of dissolved water or new compounds for recovery; the inlet of the UV photolysis equipment is connected to the outlet of...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned water spray absorption tower, the speed of the organic waste gas entering the tower body is much higher than the spray speed of the absorption liquid, which leads to the inability of the absorption liquid to contact all the organic waste gas, thereby reducing the absorption of acidic substances in the organic waste gas efficiency
