Laminated adsorption type gas filtering tower for industrial waste gas treatment

Abstract

The invention discloses a laminated adsorption type gas filtering tower for industrial waste gas treatment, and belongs to the technical field of waste gas treatment. Spraying cavities and adsorptioncavities which are arranged in a staggered manner are arranged in a cylindrical tower body; handling large contact space is large, waste gas is guided into the spraying cavities through gas inlet sleeves and gas inlet holes to be subjected to dust removal spraying treatment of a spraying mechanism. The treated waste gas is guided into the adsorption cavities from the spraying cavities through ventilation layers; the waste gas guided into the adsorption cavities is subjected to multi-layer adsorption treatment through a laminated gas filtering mechanism; the laminated gas filtering mechanism comprises a gas filtering adsorption layer and a bioactive filler layer which are arranged up and down; a plurality of groups of porous adsorption balls on the gas filtering adsorption layer and an active biological filler on the bioactive filler layer are matched to adsorb and decompose some water-insoluble harmful and difficult-to-remove impurities in the waste gas; the treated waste gas is discharged from the top end of the adsorption cavity, and wastewater generated after spraying treatment downwards passes through a filter bed filled at the bottom end part of the cylindrical tower body to be treated.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, and more specifically relates to a stacked adsorption gas filter tower for industrial waste gas treatment. Background technique [0002] Industrial production involves the processing and production of PVC, PP, ABS and other plastics. For example, plastic particles are melted and made into various equipment and workpieces, plastic parts are baked, and waste plastics are granulated, etc., which will generate certain waste gas, which contains pollution. There are many types of substances, their physical and chemical properties are very complex, and their toxicity is also different. Generally, the exhaust gas contains harmful substances such as sulfur dioxide, nitrogen oxides, and hydrocarbons. If these exhaust gases are discharged directly without treatment, they will have an impact on the atmospheric environment. . [0003] With the development of environmental protection awareness and...

Problems solved by technology

[0004] In the prior art, scrubbers are usually used to purify this kind of waste gas. Due to the high concentration of impurities and large particles in some waste gases, it is not easy to remove all the impurities by direct spraying and dust removal, and the purification has limitations. The practicability is not strong, and there are still a lot of substances that are not easily soluble in water in the exhaust gas. If only the scrubber is used for treatment, it will not achieve a good treatment effect.
