Biological membrane waste gas treatment equipment

Abstract

The invention relates to biological membrane waste gas treatment equipment, which comprises a box body, a waste gas channel arranged on the box body, a spraying system arranged at the upper portion ofthe box body and a control device, wherein the box body comprises a side wall, a bottom plate and a top cover, a biological membrane filler plate is arranged in the box body, and comprises a frame and a filler device arranged on the frame, and the waste gas channel is transversely arranged. According to the invention, the waste gas channel is transversely arranged, the flow direction of a spraying liquid and the flow direction of waste gas are perpendicularly crossed, and compared with the method that the spraying liquid flows from top to bottom and the waste gas flows from bottom to top, theabsorption effect is better, and absorption is more uniform and sufficient; the flowing direction of the waste gas is perpendicular to the direction of the spraying liquid, so that the contact absorption efficiency of the waste gas and the spraying liquid is higher; and by means of the arrangement structure, the density of the filler can be reduced, the filler can be arranged to be of a multi-layer drawable plate-shaped structure, and therefore overhaul, maintenance and cleaning work of the filler can be conducted more easily.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to equipment for purifying waste gas with biofilm. Background technique [0002] Biological treatment is the use of microbial life processes to decompose gaseous pollutants in exhaust gas into less or even harmless substances. There are a variety of microorganisms in nature, and almost all inorganic and organic pollutants can be transformed. Biological treatment does not require regeneration and other advanced treatment processes. Compared with other purification methods, it has the advantages of simple equipment, low energy consumption, safety and reliability, and no secondary pollution. [0003] Under suitable environmental conditions, microorganisms continuously absorb nutrients and carry out metabolic activities according to their own metabolic methods. Biological treatment of waste gas is to use the characteristic that nutrients are needed in the process of micr...

AI Technical Summary

Problems solved by technology

The selection of the spray pump needs to be based on the characteristics of the spray, and its lift requirements are high. In order to ensure the pressure requirements of the upper sprinkler system, the lower sprinkler system is controlled by a pressure-stabilizing valve or a ball valve, which not only increases the cost of the absorption packing tower, but also increases the cost of the absorption tower. The spraying effect of the spraying system will be affected by the opening degree of the pressure stabilizing valve or ball valve

[0007] On the other hand, the spray liquid in contact with the vertically arranged lower packing has passed through the upper packing, the water contains more impurities, the lower packing is easy to clog, and the absorption effect is not good.
