Industrial smoke dust removal method

Abstract

The invention discloses an industrial smoke dust removal method. The industrial smoke dust removal method comprises the steps of a front-stage wet electric precipitation part and a next-stage low-temperature plasma field processing part, and smoke is organically discharged through the front-stage wet electric precipitation part and the next-stage low-temperature plasma field processing part in sequence. According to the industrial smoke dust removal method, electric charges are loaded to a small amount of dust and water mist of a plasma applied field, deflection and directional movement occur in a subsequent electric field, and the dust and the water mist are collected to a polar plate and then flow down so as to be collected along the inner wall of a reactor, so that the effect of removing the dust and the water mist is achieved; the electric field intensity of the unit distance of equipment is high, and the charge and collection capability of the dust and the water mist can be increased under the action of two stages of electric fields, so that the dust and the water mist are deeply removed.

Description

technical field [0001] The invention relates to an industrial flue gas dedusting method, in particular to a wet electric dedusting method enhanced by low-temperature plasma. Background technique [0002] my country's environment is facing the most severe test in history, air pollution control is urgent, and new and stricter national standards are being formulated. Coal-fired power plants, as one of the main sources of stationary pollution, must be strictly controlled to contain heavy metal pollutants such as dust, sulfur oxides, nitrogen oxides, and mercury in the flue gas emitted, and reliable technology is the key to achieving relevant standards Assure. [0003] Wet electrostatic precipitator is a new method to realize PM2.5, SO 3 One of the key technologies for the deep purification of aerosol and other pollutants. However, this technology mainly relies on imports. There are still many imperfections in the independent technology, and the technical effect needs to be fur...

Problems solved by technology

[0003] Wet electrostatic precipitator is a new method to realize PM2.5, SO 3 One of the key technologies for the deep purification of aerosol and other pollutants. However, this technology mainly relies on imports. There are still many imperfections in the independent technology, and the technical effect needs to be further enhanced, and the comprehensive effect needs to be improved.

In addition, there are still many problems with industrial waste gas, such as water vapor, VOC gas, dust, etc., which require complex processes to solve
