A baghouse dust collector is a highly efficient, dry-type filtration system that uses fabric filter bags to capture solid particulate matter from dust-laden gas. It employs pulse-jet cleaning technology to regenerate the filter bags, allowing for continuous, on-line operation. With a dust removal efficiency exceeding 99.5% and outlet emission concentrations as low as 10 mg/m³ or less, it serves as the primary equipment for industrial dust control and material recovery.

Dust-laden gas enters the middle chamber through the air inlet and is filtered as it passes over the exterior of the filter bags; dust particles are trapped on the outer surfaces of the bags, while the cleaned gas passes through the fabric into the upper chamber (clean-air plenum) and is discharged via the air outlet. As dust accumulates on the filter bags, the system's resistance increases. A pulse controller triggers electromagnetic pulse valves at set intervals, releasing compressed air (0.4–0.6 MPa) through nozzles on a blow-pipe into the filter bags. This causes the bags to expand instantaneously and generates a reverse airflow, dislodging the dust, which then falls into the hopper and is discharged through a rotary discharge valve (star valve) that maintains an airtight seal. The cleaning process is carried out compartment by compartment and row by row, ensuring that the equipment's normal operation remains uninterrupted.

• Industrial dust control: Woodworking, construction materials, metallurgy, mining, grain processing, friction materials, etc.
• Flue gas dedusting: Boilers, incinerators, industrial furnaces/kilns, asphalt mixing plants
• Powder recovery: Material recovery during processes such as conveying, packaging, screening, and feeding
• Flue gas temperature limits depend on the filter bag material (ambient temperature type ≤120°C; high-temperature type up to 260°C)
• System negative pressure: ≤5000 Pa

Applicable Operating Conditions for Different Materials

• For dry dust and standard ambient temperatures: Carbon steel is generally sufficient.

• For high-temperature, high-humidity, or highly corrosive dust (such as chemical dust): Stainless steel is recommended.
• For environments with explosive dust: Select materials that meet explosion-proof design requirements (e.g., aluminum alloy or stainless steel).
