Pre treatment stage: The exhaust gas generated during the smelting process is usually accompanied by a large amount of particulate matter, including dust, smoke, and particulate metal particles. In the pre-treatment stage of dust removal systems, cyclone separators or wet pre dust collectors are often used to remove larger particles, thereby reducing the burden on subsequent dust removal equipment. Dust collector for metal grinding. The cyclone separator uses centrifugal force to separate larger particles, while the wet pre dust collector uses the impact and wetting effect of spray water to capture and settle particles. Main dust removal stage: In the main dust removal stage of the smelting dust removal system, equipment such as electrostatic precipitators (electrostatic precipitators) and bag filters are usually used to separate small particles. Tail gas treatment stage: The tail gas treatment stage of the dust removal system mainly involves purifying harmful gases in the exhaust gas. Common tail gas treatment methods include desulfurization and denitrification.
