Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas purification, and specifically relates to a purification device for waste gas from garbage incineration. Background Art

[0002] Waste gas purification mainly refers to the treatment of industrial waste gas such as dust particles, smoke and soot, odorous gases, and toxic and harmful gases generated in industrial places. Common waste gas purification includes factory smoke waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, chemical waste gas purification, etc.

[0003] The existing exhaust gas purification devices have certain drawbacks when in use. First, during use, the purification effect of the existing exhaust gas purification devices is poor, which in turn causes certain pollution to the environment. Moreover, the exhaust gas filtration effect of the existing exhaust gas purification devices is poor, resulting in some pollutants and impurities still remaining in the exhaust gas, which brings certain adverse effects to people's use process.

[0004] The existing patent (application number: CN202021792385.7) proposes a purification device for waste incineration waste gas, including a high-temperature purification box, and a No. 1 connecting pipe is provided on the outer surface of one side of the high-temperature purification box. The purification device for waste incineration waste gas described in the utility model is conducive to improving the purification efficiency of waste gas and avoiding waste gas pollution to the environment through the high-temperature purification box, air intake pipe, sponge filter, motor, rotating shaft, fan, controller, heating pipe and connecting core. The No. 1 connecting pipe, filter water tank and purified water are provided, which is conducive to purifying waste gas and improving the purification rate of waste gas. The exhaust box, No. 1 exhaust port, glass fiber filter, No. 2 exhaust port and activated carbon filter are provided to effectively filter impurities in the waste gas, avoid impurities from polluting the environment, and improve the practicality of the equipment. This equipment is not only simple in structure, but also easy to operate, bringing better prospects for use.

[0005] However, when the exhaust gas is purified by purified water, the exhaust gas is directly injected into the water, causing the exhaust gas to rise rapidly in the form of bubbles. The contact time between the exhaust gas and the purified water is short, and the purification effect is poor.

[0006] In view of this, this application is hereby filed. Utility Model Content
