Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically an activated carbon adsorption waste gas treatment device. Background Technology

[0002] Activated carbon is an adsorbent with a highly developed pore structure and a huge specific surface area. Its adsorption of waste gas is mainly based on physical adsorption and chemical adsorption. Physical adsorption originates from van der Waals forces between molecules. The abundant micropores (pore size less than 2 nm), mesopores (pore size 2-50 nm), and macropores (pore size greater than 50 nm) in activated carbon provide an extremely large specific surface area, typically reaching 500-1500 m² / g. Under the action of van der Waals forces, waste gas molecules are adsorbed onto the pore surface of activated carbon, as if the gas molecules are "captured" in countless tiny "traps." For example, activated carbon can effectively remove volatile organic compounds (VOCs) such as benzene and toluene from organic waste gas through physical adsorption. Chemical adsorption involves chemical reactions between the functional groups on the surface of activated carbon and waste gas molecules. The surface of activated carbon contains oxygen-containing functional groups such as hydroxyl, carboxyl, and carbonyl groups. These functional groups can react with certain waste gas molecules with specific chemical properties to form chemical bonds, thereby achieving adsorption. For example, for some sulfur- and nitrogen-containing waste gases, chemical adsorption can significantly improve the removal efficiency of activated carbon.

[0003] Chinese Patent No. 202020788544.X discloses an activated carbon adsorption waste gas treatment device, relating to the field of waste gas treatment technology. The device includes an adsorption tower, with multiple first partitions fixedly connected inside the tower. These partitions are evenly distributed within the tower, dividing the internal space into multiple adsorption chambers. Each adsorption chamber has an exhaust port at its top. Sliding grooves are formed on the inner wall of the tower and on both sides of the first partitions. Multiple filter elements are evenly distributed within each adsorption chamber, each consisting of a holding box, activated carbon, and a permeable plate. The permeable plate is fixedly connected to the bottom of the holding box, and the activated carbon is placed inside the holding box.

[0004] This invention cannot sterilize and disinfect exhaust gas during the air filtration process, thus affecting the air treatment effect. Utility Model Content
