Problems solved by technology

However, activated carbon is often used at present, but activated carbon has a small adsorption capacity for organic matter. Therefore, it is necessary to use a large amount of activated carbon each time to ensure that the concentration of organic matter in the exhaust gas reaches the emission target. The cost is high and the adsorption efficiency is low.

Abstract

The invention provides an adsorbent for purifying VOCs in air. The adsorbent comprises the following raw materials by weight: 160-170 parts of lipase solution, 60-65 parts of activated carbon, 25-30 parts of diatomaceous earth, 18-20 parts of shell powder, 12-15 parts of expanded graphite, 8-10 parts of zeolite powder, 15-18 parts of sepiolite powder, 2-4 parts of alumina, 8-10 parts of ramie fiber, 6-8 parts of loofah fiber and 8-10 parts of fragrant essence powder. Raw materials of the fragrant essence powder include cortex albiziae, fingered citron, polygala, pine needle leaves, apple eucalyptus leaves, lemon grass and fragrant wood leaves. The interaction and the synergistic effect between the 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 the VOCs in the atmosphere by the adsorbent is greatly improved. Compared with the prior art that the activated 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 atmospheric VOCs treatment, in particular to an adsorbent for purifying VOCs in the air and a preparation method thereof. Background technique [0002] VOCs usually refer to organic chemical substances with high vapor pressure and volatile under normal temperature and pressure, mainly including alkanes, alkenes and aromatic hydrocarbons, as well as various oxygenated hydrocarbons, halogenated hydrocarbons, nitrogen hydrocarbons, sulfur hydrocarbons, and low boiling points. Aromatics, etc., are a type of organic pollutants that are ubiquitous in the air and have a complex composition. Because VOCs involve many types and their physical and chemical properties are diverse, they have certain potential harm. Some highly active VOCs can undergo photochemical reactions with nitrogen oxides under certain conditions, causing an increase in surface concentration, forming photochemical smog pollution, or reacting with some free r...
