Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment devices, in particular to a multi-stage activated carbon waste gas adsorption device. Background Art

[0002] Activated carbon adsorption device is a commonly used waste gas treatment facility, usually composed of activated carbon adsorption box, fan and exhaust pipe, and activated carbon adsorption box is a key component. The activated carbon adsorption box is a set of hollow equipment composed of various metal plates. Activated carbon particles are filled into the hollow equipment or activated carbon adsorption modules are used. Activated carbon is a kind of microcrystalline carbon material mainly made of carbon material, with a black appearance, developed internal pore structure, large specific surface area and strong absorption capacity. The micropores in 1g of activated carbon material have a surface area of ​​up to 800 to 1500 square meters after expansion. Based on this highly developed pore structure, activated carbon naturally has extremely strong adsorption properties; in addition, when a molecule is captured by the pores in the activated carbon, due to the action of "van der Waals force", the molecules attract each other, and more molecules are continuously attracted until the activated carbon pores are filled.

[0003] Activated carbon adsorption boxes are generally placed vertically or horizontally. Driven by the fan, the exhaust gas enters from the air inlet of the adsorption box, is filtered by the activated carbon, and is discharged from the air outlet of the adsorption box. The layout of the activated carbon box and the structural layout of the gas flow channel inside the box directly affect the purification effect of the activated carbon adsorption box on the exhaust gas; the air flow in the existing commonly used activated carbon adsorption box only passes through a single layer of activated carbon, and the treatment of the exhaust gas by a single layer of activated carbon is often difficult to achieve ideal results; the activated carbon adsorption effect is also affected by temperature and humidity. The existing technology lacks measures to deal with temperature and humidity. Excessive temperature or humidity will cause the activated carbon adsorption capacity to decrease, affecting the adsorption effect. Utility Model Content
