A biofilm waste gas treatment equipment

Abstract

The invention relates to a biofilm waste gas treatment equipment, comprising a box body, a waste gas channel arranged on the box body, a spray system and a control device arranged on the upper part of the box body, and the box body comprises a side wall, a bottom plate and a top cover, A biofilm packing plate is arranged in the box, and the biofilm packing plate includes a frame and a packing device installed on the frame, and is characterized in that: the exhaust gas channel is arranged laterally. The waste gas channel of the present invention is arranged horizontally, and the flow direction of the spray liquid and the flow direction of the waste gas intersect vertically, and the absorption effect is better than that of the spray liquid from top to bottom and the waste gas from the bottom to the top, and the absorption is more uniform and sufficient; The flow direction of the filter is perpendicular to the direction of the spray liquid, and the efficiency of the contact absorption of the exhaust gas and the spray liquid is higher; such an arrangement structure can reduce the density of the filler, and can be set into a multi-layer drawable plate structure, so that the filler Maintenance and cleaning work is easier to carry out.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to equipment for purifying waste gas by utilizing biological membranes. Background technique [0002] Biological treatment is to use the life process of microorganisms to decompose and convert gaseous pollutants in exhaust gas into less or even harmless substances. A wide variety of microorganisms exist 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 takes advantage of the fact that nutrie...

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.
