High-activity biological waste gas purification tower

Abstract

The invention discloses a high-activity biological waste gas purification tower, comprising a tower body, wherein, the top of the tower body is provided with a clean air outlet; the bottom of the tower body is provided with a water tank and an exhaust gas inlet; a main control system is arranged at the side part of the water tank; the interior of the tower body is divided into an upper layer, a middle layer, and a lower layer, the upper layer is an aerosol separating layer, the middle layer is a bioactive exhaust gas washing layer, the lower layer is an ultramicro atomization purifying layer, and the position orders of the bioactive exhaust gas washing layer and the ultramicro atomization purifying layer can be adjusted; the ultramicro atomization purifying layer is provided with atomization catalysts and communicated with the exhaust gas inlet; the aerosol separating layer uses metal polyhedron balls as the filler and is communicated with the clean air outlet; the ultramicro atomization purifying layer is connected with the water tank through a transfer line, and the transfer line is provided with a control valve. According to the invention, exhaust gas is processed by using the combination of ultramicro atomization and washing, and multitime purification and aerosol separation, thus the advantages of good purification effect and low energy consumption of the system are achieved.

Description

technical field [0001] The invention relates to the field of waste gas purification equipment, in particular to a high-activity biological waste gas purification tower. Background technique [0002] The traditional water washing tower can only remove a single type of waste gas. Because it uses a liquid phase reaction, the reaction efficiency is not high, and it has little effect on some low-concentration waste gas with high odor; the adsorption of waste gas with solid activated carbon is slow, and it needs to overcome a lot of problems in the treatment. Wind resistance, and high energy is needed to solve the regeneration of activated carbon, the processing efficiency is low, and the energy consumption is large. [0003] Relevant industry technicians have been committed to researching and improving the existing purification tower equipment to make it more reasonable in structure, high in waste gas treatment efficiency, and better in effect. For example, a waste gas purificati...

The exhaust gas purification tower described in this patent also uses the principle of liquid phase reaction, and the reaction efficiency is not high

[0004] The patent application number is 96214172.0 The waste gas purification tower disclosed includes a tower body, a chimney is installed in the center of the tower body, and a chimney cover is provided. The body is equipped with an air inlet, and a filler outlet is placed obliquely. The air inlet is connected to the water tank. There is an exhaust gas inlet on the top right of the water tank, and a drain on the lower right side; the structure of the exhaust gas purification tower described in this patent is relatively backward. , the degassing principle is to absorb the harmful gas in the waste gas through the adsorption packing in the tower body, so that the emission concentration of the waste gas is lower than the national standard. Since only one reaction and absorption is carried out through the solid packing, the effect is general and not thorough.
