Description

Technical Field

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

[0002] Recovering organic solvents from industrial waste gas can reduce environmental pollution. Activated carbon has a good specific surface area and strong adsorption capacity, so it is often used as an adsorption medium in circulating purification systems to adsorb toxic and polluting substances in waste gas and wastewater.

[0003] Chinese patent application number 202221130949.X discloses an activated carbon adsorption device, including a pipe fitting and at least one set of activated carbon components. The pipe fitting has connection ports at both ends for connecting to a fan duct or external duct. The pipe fitting has an insertion groove that extends from the outside of the pipe fitting to its interior. The activated carbon component includes a frame corresponding to the insertion groove and activated carbon disposed within the frame. The frame can be inserted into the pipe fitting along the insertion groove, and a sealing structure is provided between the insertion groove and the frame. The frame of the activated carbon component includes a metal border and a grid. The activated carbon is made of activated carbon fiber board, pressed tightly within the frame by the grid. A conical cylinder is formed by welding a conical tube to a flange. A housing is formed by welding or finishing multiple metal plates. The pipe fitting is a round tube with notches corresponding to the housing and frame. The housing is welded to these notches. The entire activated carbon adsorption device has a simple structure, is easy to manufacture, and has low cost.

[0004] After a period of use, the surface of the activated carbon adsorption device becomes contaminated with a lot of impurities, which affects the amount of waste gas that can be introduced. The surface needs to be cleaned frequently, which is quite tedious. Moreover, once the activated carbon is saturated, the activated carbon adsorption device cannot desorb it and needs to be replaced directly, which reduces the applicability of the activated carbon adsorption device. Therefore, we propose a modular activated carbon adsorption device. Utility Model Content
