Problems solved by technology

The adsorption effect of the adsorption method depends on the performance of the adsorbent, but the adsorption effect of the commonly used activated carbon adsorption treatment is not significant at present, because the adsorption capacity of activated carbon for organic matter is small, so a large amount of activated carbon must be used every time to ensure that the exhaust gas The concentration of organic matter reaches the emission target, and the cost is relatively high

Abstract

The invention provides an organic waste gas purification adsorbent. The adsorbent includes the following raw materials by weight: 120-145 parts of lipase solution, 50-55 parts of coconut shell charcoal, 20-22 parts of diatomaceous earth, 13-15 parts of shell powder, 10-12 parts of expanded graphite, 6-8 parts of zeolite powder, 5-7 parts of attapulgite powder, 5-7 parts of bentonite, 6-8 parts oframie fiber and 4-7 parts of loofah fiber. The interaction and the synergistic effect between raw material components can be achieved by fully utilizing the specific content of each raw material component to prepare the adsorbent according to a specific preparation method, so that the removal rate of VOCs in the atmosphere by the adsorbent is greatly improved. Compared with the prior art that theactivated carbon adsorbent is used, the adsorbent is less in dosage and can greatly reduce the adsorption cost during treatment.

Description

technical field [0001] The invention relates to the field of organic waste gas treatment, in particular to an adsorbent for purifying organic waste gas and a preparation method thereof. Background technique [0002] Gaseous pollutants emitted by industry are one of the important sources of air pollution. Among them, organic waste gas is a kind of other pollutants with large discharge volume, wide pollution area, and serious harm to human body and environment. Its main component is volatile organic compounds (VOCs). [0003] At present, the commonly used treatment methods of organic waste gas purification technology include combustion method, chemical oxidation method, chemical absorption method, adsorption method and biological method, among which adsorption method is a commonly used effective method for organic waste gas purification, which uses various solid adsorbents ( Such as activated carbon, molecular sieve, etc.) to adsorb and purify the pollutants in the exhaust ga...
