Purification treatment device suitable for organic waste gas

Abstract

The invention discloses a purification treatment device suitable for organic waste gas. Several electrode assemblies annularly fit the inner wall of a shell and are connected in series, the two ends of the device are provided with a waste gas inlet and a waste gas outlet respectively, and the waste gas outlet is provided with a honeycomb-shaped photocatalyst activated carbon postposition device; each electrode assembly comprises a positive electrode pole and a negative electrode pole, and the positive electrode poles and the negative electrode poles are externally connected with a power sourceseparately via the shell through fixing bolts; the positive electrode poles and the negative electrode poles in an ionization zone are sunken inwards towards the annular center, and form gas source cavities with the inner wall of the shell; a gas source inlet is formed in the waist of the corresponding positive electrode pole or the negative electrode pole at the gas inlet end, and a gas source outlet is formed in the junction of each positive electrode pole and the corresponding negative electrode pole. Inelastic collision between high-temperature plasma and organic waste gas occur, so thatmolecular chains and chemical bonds in organic molecules are broken and decomposed into micromolecule inorganic matter, and thus preliminary purification treatment of the organic waste gas is achieved; then the honeycomb-shaped modified activated carbon photocatalyst is adopted for adsorption, harmless treatment of the organic waste gas is achieved, and the capability of the purification device oftreating the organic waste gas is improved through the parallel parts.

Description

technical field [0001] The invention relates to a waste gas treatment device, in particular to a double-series parallel organic waste gas purification treatment device, which 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., all of which belong to Toxic and harmful compounds have a great impact on human health and the ecological environment; therefore, the purification of volatile organic waste gas can effectively protect the ecological environment. [0003] The commonly used treatment methods for volatile organic waste gas mainly include combustion method and adsorption method. The combustion method is relatively simple in process, easy to o...

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
