Here, the related terms in the present invention are explained:

electrostatic dust collection, which is one of the gas dust collection methods. The dust-containing gas is electrically separated when passing through a high-voltage electrostatic field, and dust particles and negative ions are combined to be charged negatively and then tend to discharge on the surface of the anode to be deposited. In the metallurgical, chemical and other industries to purify gases or recover useful dust particles. A dust collecting method in which gas is ionized by an electrostatic field to thereby electrically adsorb dust particles to an electrode. In a strong electric field, air molecules are ionized into positive ions and electrons, and the electrons encounter dust particles in the process of running to the positive electrode, so that the dust particles are negatively charged and adsorbed to the positive electrode to be collected.

Exhaust gas treatment principle of MW-LEP (Microwave-Light ignition Plsma): the microwave firstly generates activation action on the waste gas, improves the molecular energy of the waste gas and reduces the activation energy required by the photocracking and oxidation reaction. The LEP electrodeless ultraviolet lamp tube generates high-power short-wave ultraviolet light under the action of microwaves. The short wave ultraviolet light can directly crack the waste gas molecules and can also generate high-concentration oxidizing radicals, and the oxidizing radicals can treat the waste gas molecules into water, carbon dioxide and other substances harmless to the environment in a short time (within a few seconds) under the comprehensive action of microwaves, the short wave ultraviolet light and a catalyst.

The MW-LEP equipment treats contaminants primarily through three reaction mechanisms: (1) direct cracking: strong energy carried by short-wave ultraviolet photons emitted by the microwave electrodeless ultraviolet lamp directly acts on pollutant molecules to crack the pollutant molecules; (2) indirect reaction: short-wave ultraviolet photons act on O2 and H2O to generate oxidizing groups such as O, O3 and OH, and then target pollutants are oxidized and removed; (3) microwave concerted catalysis: the microwave can increase the molecular energy of the waste gas, increase the collision frequency with the oxidized group and improve the reaction rate.
