Description

Technical Field

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

[0002] The principle of the waste gas adsorption box is that waste gas enters the adsorption tower and is adsorbed by the activated carbon in the tower for waste gas purification. The adsorption technology is a process of purifying pollutants in the discharged waste gas by attracting the contacted gas to the surface when the molecular force on the surface of the porous solid substance is in an unbalanced state. The adsorption boxes in the prior art are usually single-box adsorption boxes, which cannot change and adjust the air volume of the waste gas entering according to the generation of the front-end waste gas. When the waste gas volume becomes larger, it will cause blockage of the gas pipeline, too high air pressure in the box, and the gas cannot circulate, resulting in the abnormal operation of the adsorption box.

[0003] In the prior art, in the patent document with the publication number of CN218794948U, a multi-stage parallel activated carbon adsorption box is proposed, including an activated carbon adsorption box, its feed main pipe and discharge main pipe. The activated carbon adsorption box is composed of multiple boxes in parallel. An inlet pipe and an electric butterfly valve for gas inlet are arranged at the bottom of the activated carbon adsorption box, and the inlet pipes are collectively connected to the feed main pipe; a discharge pipe and an electric butterfly valve for gas outlet are arranged at the top of the activated carbon adsorption box, and the discharge pipes are collectively connected to the discharge main pipe; an adsorption module is arranged in the middle of the inner cavity of the activated carbon adsorption box; a monitor is arranged at the bottom of the inner cavity of the activated carbon adsorption box, and a pressure sensor is arranged inside the monitor; the activated carbon adopts a modular layout rate, which improves the adsorption efficiency, can operate independently, adjusts the number of parallel activated carbon adsorption boxes according to the size of the air flow. Even if some adsorption boxes are closed, other adsorption boxes can still carry out adsorption work, avoiding resource waste and having a wider range of air volumes to be processed.

[0004] Although the prior art achieves a modular layout and improves the adsorption effect, in the actual working process, when the flow rate increases significantly, the problem of poor filtration and adsorption effect is likely to occur. Summary of the Utility Model
