Waste gas collecting apparatus in decolorant production process

Abstract

The invention discloses a waste gas collection apparatus in the decolorant production process. The apparatus comprises a first waste gas treatment box and a second waste gas treatment box, wherein a connecting cylinder is arranged in the first waste gas treatment box, first filter cloths are arranged on the outer peripheral surface of the connecting cylinder, second filter cloths are arranged on the bottom of the connecting cylinder, a connecting part is arranged in the connecting cylinder, the connecting part is provided with liquid spraying heads and mist spraying heads, a gas supply pipe extends into the connecting cylinder, a rotating part is rotationally connected with the second waste gas treatment box, the top end of the rotating part extends into a second connecting box, a gas suction pipe is arranged on a second gas extractor and communicates with the first waste gas treatment box, a gas conveying pipe is arranged on the second gas extractor and communicates with the second connecting box, a transmission shaft is arranged on a driving apparatus and is connected with the rotating part in a transmission manner, gas discharge holes are arranged on stirring parts, the inside of each stirring part is provided with a second gas conveying channel, and a first gas conveying channel is arranged on the rotating part. The apparatus has the advantages of simple operation and convenient use, can effectively absorb and treat the waste gas generated during the decolorant production process, has good purification effects and high purification efficiency, and significantly reducesthe pollution to the atmospheric environment.

Description

technical field [0001] The invention relates to the technical field of decolorizing agent production, in particular to a waste gas collection device in the decolorizing agent production process. Background technique [0002] According to the principle of decolorization, decolorizers are divided into three categories: flocculation decolorizers, oxidative decolorizers and adsorption decolorizers; flocculation decolorizers are quaternary ammonium cationic polymer compounds with multiple functions such as decolorization, flocculation, and degradation of CODcr; adsorption decolorizers are generally Activated carbon, white clay or adsorption resin can directly filter out impurities and oxides in oil products, integrating impurity removal, deodorization, decolorization and separation into one, turning blackened oil products into light-colored transparent liquids , the acid value and chromaticity of the processed diesel oil meet the national fuel standards; the oxidative decolorizin...
