Description

Technical Field

[0001] This utility model relates to the technical field of soil waste gas treatment and purification devices, and in particular to an in-situ soil waste gas treatment and purification device. Background Technology

[0002] With the acceleration of industrialization and urbanization, soil pollution has become increasingly serious. In industrial production, large amounts of wastewater and waste residue containing heavy metals and organic pollutants are discharged from the chemical, metallurgical, and electroplating industries and enter the soil without proper treatment. At the same time, the deposition of harmful components in exhaust gases also exacerbates soil pollution. In the agricultural sector, the long-term overuse of pesticides and fertilizers, as well as sewage irrigation, has led to the continuous accumulation of harmful substances in the soil. According to relevant statistics, the rate of soil pollution exceeding standards is high in some parts of my country. Polluted soil continuously releases exhaust gases, including volatile organic compounds, malodorous gases, and some carcinogens such as benzene, toluene, xylene, and hydrogen sulfide. These exhaust gases not only pollute the surrounding atmospheric environment, leading to a decline in air quality and causing severe smog, but also harm human health through respiratory and skin contact, increasing the risk of respiratory diseases and cancer, seriously affecting the quality of life and health of residents.

[0003] A search revealed Chinese Patent Publication No. CN216909841U, which discloses a soil waste gas purification device. This device relates to the technical field of soil waste gas treatment. The application includes a reaction tower and a catalyst cylinder connected to the reaction tower via a catalyst pipe. The top of the reaction tower has an exhaust port. The end of the catalyst pipe furthest from the catalyst cylinder extends into the reaction tower and is connected to a liquid supply pipe. An air inlet pipe for introducing soil waste gas penetrates the side wall at the bottom of the reaction tower. A reaction pipe connected to the air inlet pipe is located inside the reaction tower. The reaction pipe is spirally extended upwards, and several spray heads connected to the liquid supply pipe are installed inside the reaction pipe. A drain port is located at the bottom of the reaction pipe. A spray assembly is located inside the top of the reaction tower. This application, through the cooperation of the spirally arranged reaction pipe and the spray assembly, helps to extend the emission path of soil waste gas, thereby improving soil... The degree of reaction between soil waste gas and catalyst is crucial for improving the purification effect of soil waste gas. However, the above-mentioned technologies for in-situ treatment of soil waste gas, such as adsorption, biodegradation, and chemical oxidation, each have their limitations. Adsorption relies on the physicochemical adsorption of pollutants in waste gas by adsorbent materials, but adsorbent materials are easily saturated and are not effective for some high-concentration, difficult-to-adsorb pollutants. Activated carbon fiber has a good adsorption effect on low-concentration volatile organic compounds, but for high-concentration, complex halogenated hydrocarbons, the adsorption capacity and adsorption rate will decrease significantly. Biodegradation utilizes the metabolic activities of microorganisms to decompose pollutants. However, the growth and metabolism of microorganisms are subject to harsh environmental conditions. Changes in any factor such as soil pH, temperature, humidity, and nutrient content can affect microbial activity, leading to unstable degradation efficiency. Utility Model Content
