Ionization device suitable for organic waste gas treatment

Abstract

The invention discloses an ionization device suitable for organic waste gas treatment. Electrode assemblies fit the inner wall of a shell and are annularly arranged, and the two ends of a cavity are provided with a gas inlet and a gas outlet respectively; each electrode assembly comprises a positive electrode pole at one end and a negative electrode pole at the other end, and the positive electrode poles and the negative electrode poles are externally connected with a power source separately via the shell through fixing bolts respectively; the positive electrode poles and the negative electrode poles in the ionization area are sunken inwards towards an annular center to form gas source cavities with the inner wall of the shell; a gas source inlet is formed in the portion, in the waist of each positive electrode pole or each negative electrode pole, of one end of the gas inlet, and a gas source outlet is formed in the joint of each positive electrode pole and the corresponding negativeelectrode pole; a gas flow channel is a concave channel formed after inward sinking. According to the ionization device, inelastic collision occurs between generated high-temperature plasma and organic waste gas, so that molecular chains and chemical bonds in organic molecules are broken and decomposed into micromolecule inorganic matter (carbon dioxide, water, nitrogen and the like), and thus organic waste gas purification treatment is achieved; in the treatment process, adsorbents are not needed, secondary pollution problems do not occur either, and thus the device has very high practicability and wide applicability.

Description

technical field [0001] The invention relates to a waste gas treatment device, in particular to an ionization device suitable for organic waste gas treatment, and belongs to the technical field of waste gas purification treatment. Background technique [0002] In the production process of petrochemical and chemical industries, industrial waste gas containing a large amount of volatile organic compounds is discharged into the atmosphere. These volatile organic waste gases mainly include ketones, benzene, alcohols, halogenated hydrocarbons, etc. It is a toxic and harmful compound, which has a great impact on human health and the ecological environment; therefore, the purification and treatment of volatile organic waste gas can effectively protect the ecological environment. [0003] The commonly used methods for treating volatile organic waste gas mainly include combustion method and adsorption method. The combustion method is relatively simple in process, easy to operate, and...

AI Technical Summary

Problems solved by technology

The combustion method is relatively simple in process, easy to operate, and can recover the heat after combustion, but cannot recover useful substances. It is only effective for high-concentration organic waste gas, and it is easy to produce secondary pollution during the combustion process; the adsorption method uses adsorbents to absorb organic waste gas. It is suitable for treating low-concentration organic waste gas. The disadvantage is that the adsorbent is difficult to regenerate and needs to be replaced continuously
