Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and particularly relates to a multi-stage spray absorption device. Background Technique

[0002] In industrial production, along with the production of products, wastewater and waste gas are generally generated. Due to environmental protection requirements, high-concentration waste gas cannot be directly discharged into the atmosphere and must be treated to reduce the concentration to meet the emission standards before it can be discharged. In recent years, the country's requirements for environmental protection have been continuously increased, which also puts forward higher requirements for waste gas treatment devices and processes.

[0003] The existing Chinese utility model patent with the reference publication number: CN216755927U discloses a multi-stage spray absorption device, which includes a wet gas purification tower and an essential oil atomizer. The waste gas outlet of the wet gas purification tower is connected with a gas distribution pipeline, the outlet end of the gas distribution pipeline is connected with a chimney, the essential oil outlet end of the essential oil atomizer is connected with a high-pressure blower, the outlet of the high-pressure blower is connected with a delivery pipe, the gas distribution pipeline is fixedly provided with a lower pipe hoop and an upper pipe hoop, the bottom end of the lower pipe hoop is integrally formed with a connection port fixedly connected with the delivery pipe, the top end of the lower pipe hoop is integrally formed with an air knife port extending into the gas distribution pipeline, and two flow guiding plates are fixedly arranged on the inner wall of the air knife port. By atomizing the deodorant into a mist shape through the essential oil atomizer and making it fully contact with the gas treated by the wet gas purification tower, and through the flow guiding plates in the air knife port, the mist-shaped deodorant first diffuses and then re-converges into a mist wall, ensuring that the mist-shaped deodorant is evenly distributed and the deodorization efficiency is high.

[0004] Although the above-mentioned multi-stage spray absorption device solves the problem that the concentration of the odor component in the waste gas fails to reach the emission standard by atomizing the deodorant into a mist shape through the essential oil atomizer and making it fully contact with the gas treated by the wet gas purification tower, the existing multi-stage spray absorption device has a poor spray effect and is not convenient for grading dosing.
