Description

Technical Field

[0002] Waste gas purification mainly refers to the work of treating industrial waste gas generated in industrial sites, such as dust particles, flue gas soot, odor gas, toxic and harmful gases. Common waste gas purification includes factory soot waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid-base waste gas purification, chemical waste gas purification, etc. If directly discharged into the atmosphere, it will pollute the air. Therefore, industrial waste gas cannot be directly discharged into the atmosphere and needs to be treated until it meets the emission standards before being discharged.

[0003] The existing deodorization method utilizes the characteristic that certain substances in the odor gas react chemically with the liquid medicine to remove certain odor components.

[0004] Most of the existing devices directly introduce the waste gas into the liquid medicine during waste gas treatment. During the treatment, the mixing efficiency of the liquid medicine and the waste gas is relatively low, and the waste gas cannot be fully mixed with the liquid medicine, resulting in poor treatment effect. Therefore, a waste gas treatment and purification device is proposed. Content of the Utility Model
