Adsorption purification device for industrial oil-containing waste gas treatment

Abstract

The invention discloses an adsorption purification device for industrial oil-containing waste gas treatment, and belongs to the technical field of waste gas treatment. The introduced waste gas is subjected to spraying treatment through a hollow washing box, the treated water body is subjected to adsorption treatment by the honeycomb ceramic adsorption filler filling in a straw hat-shaped flow guide box; the washed waste gas is brought into a conical adsorption emulsification disc through the gas guide adsorption mechanism, greasy dirt particles in the waste gas are adsorbed by the greasy dirtadsorption fiber layer and the greasy dirt capture crude fibers in the conical adsorption emulsification disc, oil stains in the waste gas are adsorbed in the conical adsorption emulsifying disc and then are in contact with an emulsifying agent on the emulsion guide fiber surface; after the emulsification reaction, the oil stain is decomposed; the oil droplets fall off and are desorbed to the airguide adsorption mechanism by utilizing the matching of the self gravity of the emulsion oil droplets and the oleophobic characteristic of the bottom end surface of the conical adsorption emulsification disc so that the adsorption blockage phenomenon caused by excessive oil stains on the conical adsorption emulsification disc is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, and more specifically relates to an adsorption purification device for industrial oily waste gas treatment. Background technique [0002] Existing fields such as printing and dyeing, petrochemical, paint, and food processing industries will emit high-concentration organic oil-containing waste gases such as smoke, oil stains, etc. during product processing. If these organic oil-containing waste gases are directly discharged into the air, It is bound to cause pollution to the atmospheric environment. [0003] For the volatile organic oily pollutants in the exhaust gas, the treatment methods commonly used at present include: wet scrubbing method, incineration method, adsorption method, ozone treatment method, masking agent method, biological filtration method and biological dripping filtration method, etc. [0004] The most used in the prior art is to wash the exhaust gas, and at the sa...

Problems solved by technology

[0004] The most used in the prior art is to wash the exhaust gas, and at the same time cooperate with the adsorption filter packing to absorb the oil and smoke particles in the exhaust gas. However, it will be found during the treatment that the adsorption filter packing will adhere to a large amount Oil and smoke particles will cause adsorption blockage, which will affect the adsorption and filtration effect, and the usability is limited; in addition, when the adsorption filter filler reaches adsorption saturation, the oil attached to it will gather into beads and drip into the processing equipment.
