Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment, in particular to a waste gas adsorption and catalytic decomposition device. Background Art

[0002] The organic waste gas released by the reactor during the production process is an irritating gas and is also a colorless gas. If the organic waste gas is discharged into the atmosphere, it will be harmful to people's skin, blood, heart, lungs, liver, nerves, and eyes through breathing or direct action on the human body, and will seriously affect the surrounding environment.

[0003] At present, common treatment methods are combustion, adsorption, absorption, etc. The combustion method has high temperature requirements for decomposing organic waste gas and is not safe enough; the adsorption method is indeed highly efficient, but the adsorption capacity of the adsorbent is limited; furthermore, the absorption effect of the absorption method is poor, and the regeneration of the absorbent is very inconvenient and consumable, so the catalytic combustion method is generally used to purify organic waste gas.

[0004] The catalytic combustion method is used to purify organic waste gas, such as an organic waste gas purification system with publication number CN215428095U. The waste gas is adsorbed by installing activated carbon inside the adsorption tower. However, there is a distance difference in the adsorption of activated carbon. The utilization rate of activated carbon close to the air inlet pipe of the adsorption tower is better, while the utilization rate of activated carbon far from the air inlet pipe of the adsorption tower is poor. After a period of purification, the activated carbon needs to be replaced, but there is a situation where the utilization rate of some activated carbon is poor.

[0005] Therefore, it is necessary to provide an exhaust gas adsorption and catalytic decomposition device to solve the above technical problems. Utility Model Content
