Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to an activated carbon adsorption box for waste gas treatment and purification. Background Art

[0002] Activated carbon is the best purification equipment for treating organic waste gas and odor treatment. Activated carbon adsorption is an effective measure to remove the odor of water, natural and synthetic dissolved organic substances, micro-pollutants, etc. Most relatively large organic molecule, aromatic compounds, haloalkynes, etc. can be firmly adsorbed on the surface or voids of activated carbon, and have obvious removal effects on humus, synthetic organic substances and low-molecular-weight organic substances. As a deep purification process, activated carbon adsorption is often used for the final treatment of wastewater, and can also be used for the purification treatment of production water and domestic water. When there are more dust and particulate matters, the activated carbon adsorption device can be used together with a water curtain machine, a water spray tower and UV plasma at the same time to achieve the standard discharge of waste gas purification;

[0003] After retrieval, the Chinese patent with the publication number of CN207445902U discloses a new type of integrated activated carbon adsorption and purification equipment.

[0004] In the above technical solution: it includes a filter box housing, air inlets and outlets, a flow equalizing plate, a pretreatment unit, an activated carbon adsorption unit, and a fan. An air inlet is arranged on one side of the box body, and the opposite side is the air outlet. The fan and the waste gas purification equipment are highly integrated in a box body. Waste gas enters the activated carbon adsorption and purification equipment from the air inlet, first passes through the flow equalizing plate, and the flow equalizing plate is a stainless steel perforated plate. The waste gas after passing through the flow equalizing plate enters the pretreatment unit for filtration, and the pretreatment unit is provided with primary and secondary filters. The waste gas enters the activated carbon adsorption unit after passing through the pretreatment unit. The activated carbon adsorption unit uses high-quality honeycomb activated carbon, which has the advantages of high adsorption efficiency, long regeneration period, and convenient replacement. The induced draft fan is installed at the end inside the activated carbon box body, and the whole equipment is of an integrated structure;

[0005] However, in the above solution, activated carbon purifies the air by adsorbing impurities on the activated carbon. Therefore, the purification efficiency of the adsorption box is inversely related to the saturation of the activated carbon. Therefore, it is necessary to frequently replace the activated carbon, and its integrated box body is not convenient for replacing the activated carbon. To a certain extent, the purification effect of the activated carbon on waste gas depends on the length passing through the activated carbon.

[0006] Therefore, we propose an activated carbon adsorption box for waste gas treatment and purification. Utility Model Content
