Plasma waste gas treatment device

Abstract

The invention relates to a plasma waste gas treatment device which comprises a cuboid horizontal type shell. A water gas inlet and a waste gas treatment outlet are formed in the two ends of the horizontal type shell. The plasma waste gas treatment device is characterized in that a first metal wire gauze strainer, a first-stage plasma treatment core, a second metal wire gauze strainer and a second-stage plasma treatment core are sequentially arranged in the shell from the waste gas inlet; a waste gas treatment air inducing pipe is connected to the waste gas treatment outlet, and an air draft fan is arranged on the waste gas treatment air inducing pipe; and an electronic control cabinet is installed on one side of the shell, overhauling openings are formed at least in the positions, corresponding to the plasma treatment cores, of the other side of the shell, and opened doors or movable doors are arranged on the overhauling openings. The plasma waste gas treatment device has the beneficial effects of being simple in structure, safe, reliable, easy to operate, convenient to install and maintain, low in running cost, high in treatment efficiency, capable of guaranteeing that waste gas is normally treated for a long time, capable of meeting the requirement for the waste gas treatment effect of coating equipment and the like.

Description

technical field [0001] The invention relates to a plasma exhaust gas treatment device, which is mainly used for exhaust gas treatment of coating equipment and belongs to the technical field of exhaust gas treatment. Background technique [0002] Plasma is the fourth state of matter after the three states of solid, gas, and liquid. It is composed of positive ions, negative ions, electrons and neutral ions. Because the total number of positive and negative charges in the system is equal, it is called "plasma". . [0003] Low-temperature plasma technology is a new technology for waste gas treatment developed in recent years. The principle of low-temperature plasma treatment of waste gas is: when the applied voltage reaches the gas discharge voltage, the gas is broken down to produce electrons, various ions, atoms and free A mixture of radicals; the degradation of pollutants by low-temperature plasma is to use the action of these high-energy electrons, free radicals and other a...

AI Technical Summary

Problems solved by technology

[0004] At present, the technology of using plasma for waste gas treatment is a mature technology. There are many kinds of plasma waste gas technologies disclosed in the Chinese patent bulletin. For example, the patent application number is: 200980135309.9 discloses a "plasma treatment method and equipment" , the structure of the plasma technology disclosed in this patent application is quite complicated, so it is difficult to apply to the exhaust gas treatment in the existing coating equipment; and the exhaust gas treatment equipment with simple structure has poor exhaust gas treatment effect, etc. Problems, especially for small-scale waste gas treatment of some small-scale coating equipment, there is currently no plasma waste gas treatment equipment that meets the requirements of waste gas treatment, has a simple structure, is easy to install and maintain, and can ensure the normal treatment of waste gas for a long time
