[0002] Waste gas refers to the gas containing pollutants emitted during industrial production, transportation, agricultural activities, etc. The pollutants in the waste gas include sulfur dioxide, nitrogen oxides, volatile organic compounds, suspended particulate matter and heavy metals, which are harmful to human health and the environment. In order to reduce the harm of waste gas to the environment, waste gas purification devices are generally used to purify the waste gas, reduce the concentration of pollutants in the waste gas to the emission standard range specified by environmental protection standards, and protect the environment and human health;

[0003] Exhaust gas usually carries a lot of heat and particulate matter. Existing exhaust gas purification towers cannot pre-cool the exhaust gas before purification, nor pre-treat the particulate matter in the exhaust gas. These problems can easily affect the effect of subsequent purification and reduce the efficiency and purification rate of exhaust gas purification.

[0004] In order to solve the above problems, this application proposes an environmentally friendly waste gas purification device. Utility Model Content
