Low-temperature plasma waste gas purification equipment

Abstract

The invention discloses low-temperature plasma waste gas purification equipment. The low-temperature plasma waste gas purification equipment comprises a low-temperature plasma reaction chamber; the low-temperature plasma reaction chamber is provided with both a gas inlet and a gas outlet; a filtering net, a filtering device and a plasma generation device are arranged in the low-temperature plasmareaction chamber sequentially; the filtering device comprises a bracket as well as a filtering layer, a demisting layer and an activated carbon adsorbing layer which are arranged in the bracket sequentially; a spraying pipe is arranged at the top of the low-temperature plasma reaction chamber; a water return pipe is arranged at the bottom of the low-temperature plasma reaction chamber; one end ofthe water return pipe is connected with a water storage tank and the other end of the water return pipe is connected with an activated carbon water tank; and one end of the spraying pipe is connectedwith a spraying head and the other end of the spraying pipe is connected with the activated carbon water tank through a water pump. The low-temperature plasma waste gas purification equipment can prolong the service life and improve the gas purification effect, has a good purification effect on the waste gas, solves the problems of incomplete purification and insufficient purification degree, andenables the discharged gas to be more environment-friendly.

Description

Technical field: [0001] The invention belongs to the field of exhaust gas purification equipment treatment, and in particular relates to a low-temperature plasma exhaust gas purification equipment. Background technique: [0002] At present, there are more and more types of waste gas purification equipment. With the continuous development of industry, the traditional waste gas purification process can no longer meet the current demand for organic waste gas purification. At present, the use of low-temperature plasma technology to control the emission of organic waste gas One of the methods of pollution. [0003] In the prior art, low-temperature plasma is the fourth state of matter after solid state, liquid state, and gas state. Low-temperature plasma degrades pollutants by using active particles such as high-energy electrons and free radicals and pollutants in exhaust gas to make pollutant molecules in the extreme Decomposition occurs in a short period of time, and various s...
