[0002] Atmospheric control and pollution control are crucial links in environmental protection, aiming to reduce pollutant emissions in the atmosphere, protect air quality, and ultimately protect the ecological system and public health. During the hazardous waste incineration process, the cloth bag dust collector is one of the key environmental protection equipment for capturing fine dust and harmful gases generated during the incineration process. The main function of the cloth bag dust collector is to filter particulate matter in the air, thereby reducing pollutant emissions. Its working principle is based on the fact that when air flows through the cloth bag, dust is captured on the surface of the cloth bag, and clean gas is discharged through the cloth bag. In this dust removal system, the ash discharging device plays a crucial role.
