Description

Technical Field

[0001] This utility model relates to the field of waste gas purification and treatment technology, specifically a waste gas purification and treatment device for environmental protection engineering. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life, especially from chemical plants, steel mills, pharmaceutical factories, coking plants, and oil refineries. The waste gas emitted by these plants has a strong odor, seriously pollutes the environment, and affects human health. Waste gas contains many types of pollutants with very complex physical and chemical properties and varying degrees of toxicity. Therefore, it is often necessary to purify the waste gas during the emission process to reduce its harm to the environment.

[0003] In the existing technology, in order to avoid air pollution from exhaust gas, treatment devices are generally used to purify the exhaust gas before it is discharged.

[0004] However, most existing treatment devices generally rely solely on activated carbon mesh for adsorption during the purification of waste gas. While this method achieves purification, the presence of large particulate matter in the waste gas causes these particles to adhere to the surface of the activated carbon mesh, necessitating frequent mesh replacements to maintain the treatment effect. Therefore, this invention proposes a waste gas purification device for environmental engineering to address the aforementioned problems. Utility Model Content

[0028] When it is necessary to purify the exhaust gas, the exhaust gas can first be initially filtered through the filter screen 6 and the barrier screen 11 to block larger particulate impurities in the exhaust gas. Then, the activated carbon screen 3 is used in conjunction with the exhaust gas treatment equipment 1 to purify the exhaust gas. The setting of the filter screen 6 and the barrier screen 11 can prevent larger particulate impurities from adhering to the surface of the activated carbon screen 3 and affecting the purification effect of the activated carbon screen 3.

[0030] When in use, after the upright plate 7 is fixed, the filter screen 6 and the barrier screen 11 can filter and block larger particles in the exhaust gas, preventing larger particles from directly adhering to the surface of the activated carbon screen 3. When the limiting rod 17 is inserted into the support rod 5, the upright plate 7 can be pushed by the setting of the push plate 19, so that the upright plate 7 and the end face of the moving port 4 are precisely fitted. The slider 23 can move within the receiving groove 21 and the limiting block 24 can move within the limiting port 22, thereby avoiding the problem of conflict between the push plate 19 and the upright plate 7.
