Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature waste gas treatment, in particular to a high-temperature waste gas treatment device. Background Art

[0002] Waste gas refers to the toxic and harmful gases discharged by humans in the process of production and life, especially the waste gas produced by chemical plants, steel mills, pharmaceutical plants, coking plants and refineries, as well as human life. The waste gas emitted has a strong odor, seriously polluting the environment and affecting human health. Some factories will produce a lot of high-temperature waste gas during production, and direct emission will affect the surrounding working environment. Therefore, high-temperature waste gas treatment equipment is needed for treatment.

[0003] Some high-temperature exhaust gas treatment devices currently on the market: for example, the utility model patent with authorization announcement number CN218980870U discloses a high-temperature exhaust gas treatment device, which turns on the driving motor in the cleaning mechanism to rotate the spiral blade, and scrapes off the impurities adsorbed on the inner wall of the cylindrical filter screen through the rotating spiral blade, and moves the impurities in the cylindrical filter screen to the right through the rotating spiral blade and discharges them through the straight pipe, thereby making it easier for users to clean the impurities inside the cylindrical filter screen. However, after the high-temperature exhaust gas enters the device, it will come into contact with the cylindrical filter screen. On the one hand, the higher temperature may cause the filter screen material to soften, deform, and age at high temperature, thereby reducing its filtering effect and service life. On the other hand, after the filtered high-temperature exhaust gas is discharged through the exhaust pipe, since it contains higher heat energy, this heat energy is released into the atmosphere in the form of thermal radiation, which may aggravate the greenhouse effect and affect the environment.

[0004] Therefore, we propose a high-temperature exhaust gas treatment device to solve the above problems. Utility Model Content
