Product Overview
Industrial baghouse is a dry filtration device that uses bag-shaped filter media to capture particulate matter from dust-laden gas. Dust-laden gas enters the housing from the inlet, dust is retained on the outer surface of the filter bags, and clean gas is discharged through the outlet. When dust accumulates to a set thickness, the compartmented pulse cleaning system injects compressed air in sequence to shake dust into the hopper. The equipment is suitable for dust treatment in steel, cement, chemical, power, metallurgy, mining, building materials, foundry, boiler, and asphalt mixing industries.

Selection & Comparison Notes
• Compartmented pulse cleaning allows bag replacement without full shutdown. Each filter compartment has an independent pulse valve; cleaning is performed compartment by compartment while the others continue filtering.
• Hopper uses gravity pre-separation to reduce bag load and extend cleaning cycle.
• Filtration velocity is selected within 1.2–2.0 m/min according to dust concentration and media.
• For high-concentration dust (e.g., steel plant sintering machine tail, coke screening transfer station), lower velocity is used; for low-concentration dust, velocity can be increased to reduce equipment size.
• Compartmented pulsing reduces mechanical wear frequency on pulse valve diaphragms, cages, and bags, lowering consumable replacement cost.

Quality Control
Filter bags and cages are inspected piece by piece before delivery, confirming complete stitching, no deformation of bag top spring ring, and no missed welds on cages. Pulse valves are tested one by one for diaphragm sealing and pulse response. After housing welding, weld seams are inspected; hopper-to-housing connection is checked for sealing. Pre-assembly is completed in the factory to check tube sheet hole and cage fit, and pulse pipe and bag alignment. 100% inspection before packing. Third-party inspection accepted. The factory has supplied this equipment to steel sintering, cement kiln tail, and foundry projects, and uses this field data to set filtration velocity and cleaning parameters.
FAQ
Q: Can you select the model based on our flue gas conditions?
A: Yes. Please provide air volume, flue gas temperature, dust concentration, particle size distribution, corrosive components, and site space limits. We will determine filtration area, filtration velocity, bag material, and cleaning parameters.
Q: Are bags and cages supplied separately as spare parts?
A: Yes. Bags and cages can be ordered separately by model or purchased with the complete unit. Bag materials include acrylic medium-temperature needle felt, high-temperature Metas membrane, and high-temperature PPS needle felt. Cages are supplied as matching parts.
