Problems solved by technology

[0002] There are many kinds of industrial organic waste gas, the composition is complex, the concentration fluctuates greatly and the change is irregular, and its treatment is relatively difficult.
[0003] The purification and treatment processes adopted by the existing organic waste gas purification devices include catalytic combustion method, activated carbon adsorption method, condensation method, absorption method and plasma oxidation method, etc., which solve the pollution of organic waste gas to the environment to a certain extent, but the above purification and treatment processes There are many problems: the catalytic combustion method is not suitable for the treatment of large air volume, low concentration, and unstable organic waste gas; the post-treatment processes such as activated carbon adsorbent regeneration and solvent recovery are complicated; the application range of condensation method and absorption method is more limited; When the bulk oxidation method is used to treat organic waste gas with a large air volume, the gas stays in the plasma action area for a short time, resulting in a decrease in purification efficiency

Abstract

The invention discloses a purification device for organic waste gas, which comprises a waste gas purification tower and is characterized in that the gas purification tower comprises a shell body. An ion body purifier and an activated carbon adsorption bed are arranged in the shell body, a waste gas inlet is arranged on the shell body and is positioned under the activated carbon adsorption bed, and the ion body purifier is positioned above the activated carbon adsorption bed. The activated carbon adsorption bed is provided with a packing layer, and an electric heating tube is arranged in the packing layer. The invention has the advantages of simple treatment process, high purification efficiency, small filling amount of activated carbon and simple regeneration process operation, and is applied to treat the unstable organic waste gas with large wind capacity and low concentration.
