Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas purification technology, specifically to an automatic catalytic purification device for industrial combustion waste gas. Background Technology

[0002] Industrial waste gas is a general term for various pollutant gases emitted into the air during fuel combustion and production processes within a factory area. These waste gases include carbon dioxide, carbon disulfide, hydrogen sulfide, carbon monoxide, etc. When emitted into the atmosphere, they will pollute the air and need to be purified by purification devices.

[0003] In the prior art, Chinese utility model application number CN202320715348.3 discloses an industrial waste gas purification device, including a body. When waste gas enters the body, it is first filtered by a filter screen in the air inlet pipe to remove dust and impurities. The filtered dust and impurities fall into the ash box through the ash outlet for unified collection. The filtered waste gas enters the combustion chamber, where gas from the gas cylinder is ejected from the gas gun to fully combust the waste gas, thereby removing combustible waste gas. By lifting the partition sealing plate, the waste gas enters the purification chamber through the gap at the bottom of the partition sealing plate. At the same time, the motor is started to drive the rotating rod and the perforated mesh plate on the support rod to adsorb toxic waste gas substances in the purification chamber, accelerating its adsorption and purification efficiency. Similarly, lifting the partition sealing plate allows the gas to enter the disinfection chamber through the gap. The gas is irradiated by multiple ultraviolet lamps in the disinfection chamber for the final disinfection and sterilization step. After purification, the waste gas can be discharged into nature.

[0004] In the above-mentioned technical solution, the exhaust gas needs to be burned by humans during use, which increases the cost of exhaust gas treatment. At the same time, the separation and sealing plate needs to be opened and closed manually, which increases the number of manual operation steps. The purification effect of exhaust gas needs to be further improved. Therefore, we need to propose an automatic catalytic purification device for industrial combustion exhaust gas.
