Organic waste gas filler absorption tower

Abstract

The invention relates to the technical field of energy conservation and environmental protection, and discloses an organic waste gas packing absorption tower which comprises an absorption tower shell, a packing layer is fixedly installed in the absorption tower shell, a bearing plate is fixedly installed at the bottom of the packing layer and mainly used for bearing the packing layer, and an air pipe is arranged on the outer side of the absorption tower shell. According to the invention, an air pipe orifice which distributes air directly at the bottom of the filler layer originally extends into the filler layer through the through pipe, so that waste gas flow is prevented from directly impacting a microbial film at the bottom of the filler layer, and the probability that microorganisms at the bottom of the filler layer fall off is reduced; a biological film is impacted by up and down tubes, the falling amount of organisms at the upper end is reduced under the effect of adsorption force among the microorganisms at the lower end, and the microorganisms at the lower end are relatively large in friction force due to the action of adsorption force among the microorganisms, so that even if the microorganisms are subjected to gas-phase impact, the adsorption force among the microorganisms can also improve the wall hanging effect, and the degradation efficiency of the bottom of the filler layer is effectively improved.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to an organic waste gas packed absorption tower. Background technique [0002] Biological filtration technology treats organic waste gas mainly through biological filter beds and biofilm absorption towers, using the microorganisms or biofilms growing inside the filter beds and packing towers to degrade the organic matter in the waste gas, thereby achieving the effect of purifying the waste gas, in which the biofilm absorbs The main structure of the tower includes the tower body and the packing inside the tower body. The material of this packing uses corrugated metal orifice plate regular packing to improve the mass transfer efficiency between the gas phase and the liquid phase. The nutrient solution used for circulation is transferred from the packing Spray from above and down, inoculate the hanging film on the surface of the filler to form a biofi...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use process of the existing waste gas packed absorption tower proposed in the background technology, the present invention provides a kind of organic waste gas packed absorption tower, which has the functions of reducing the loss of biofilm in the packing layer and improving the waste gas degradation efficiency at the bottom of the bottom packing layer. Advantages, it solves the problem in the above-mentioned background technology that the bottom of the packing layer has no supporting force and the blowing of the airflow reduces the wall-hanging effect of the biofilm, which leads to the problem of microbial shedding
