Description

Technical Field

[0001] This utility model belongs to the field of acetone adsorption and recovery technology, and in particular relates to an acetone adsorption and recovery device. Background Technology

[0002] Acetone is an organic solvent, usually a colorless, transparent, volatile liquid with a pungent odor. In industrial processes, acetone is used as a solvent or chemical raw material. Due to its high volatility, it is discharged with exhaust gas. In order to effectively reduce environmental pollution, save resources and reduce production costs, acetone adsorption and recovery devices are used to recover acetone from exhaust gas.

[0003] Existing acetone adsorption and recovery devices often employ an absorbent spraying method for acetone adsorption and recovery. However, since the exhaust gas contains a large number of particulate impurities, these impurities compete with acetone for adsorption sites on the absorbent liquid surface. Because these impurities occupy some adsorption sites, the contact opportunity between the absorbent liquid and acetone molecules is reduced, leading to a decrease in acetone adsorption efficiency. Furthermore, in absorbent spray adsorption, the spray heads are often fixed, resulting in uneven spraying and reduced gas-liquid contact efficiency.

[0004] To address these issues, we provide an acetone adsorption and recovery device. Utility Model Content

[0005] The purpose of this invention is to provide an acetone adsorption and recovery device that solves the problems of poor spraying effect and susceptibility to particulate impurities when adsorbing and recovering acetone in existing acetone adsorption and recovery devices by combining a particle filter component and a rotating spray component.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0032] When the rotating rod 19 rotates, it drives the second gear 20 to rotate, which in turn drives the cleaning brush 10 to rotate and clean the surface of the filter cartridge 6, ensuring the airflow of the filter cartridge 6. The cleaned particles enter the discharge pipe 11 under the action of the guide plate 13, and can be discharged by periodically opening the stopcock valve 12. In this way, through the synergistic effect of the particle filtration assembly and the rotary spray assembly, the problems of particle interference and uneven spraying in traditional acetone recovery are solved, combining high efficiency, automation and environmental protection.
