The LMF Series Offline Pulse Jet Baghouse Dust Collector is a high-efficiency, energy-saving, and reliable dry-type dust removal system designed for industrial flue gas with high dust concentration and continuous operation. Widely used in metallurgy, foundry, cement, chemical, power, and biomass energy industries—for dust control of electric furnaces, medium-frequency furnaces, mills, dryers, and boilers.

Featuring compartmentalized chambers and offline pulse jet cleaning, the system enables sequential filtration and maintenance without shutdown. The cleaning process does not affect normal operation, effectively preventing "re-entrainment" of dust. Ensures long-term stable performance under high negative pressure (≤-8000 Pa) and large airflow (10,000–500,000 m³/h). Dust emission is stably controlled at ≤10 mg/Nm³, meeting GB 16297 and ultra-low emission regulations.

Dust-Laden Gas Inlet: Dusty gas enters the middle chamber via inlet duct, uniformly distributed into each filtration compartment through flow-guiding plates. Coarse particles settle into hoppers by gravity.

Filtration: Fine dust is captured on the filter media surface. Clean gas passes through the bags into the clean-air chamber and is discharged via outlet duct.

Offline Cleaning: When pressure drop in a chamber reaches the setpoint, the lift valve closes—taking the chamber offline. The solenoid valve activates, injecting compressed air through the blow pipe into the bags, causing rapid expansion and dust shedding into the hopper. After cleaning, the chamber resumes filtration.

Dust Collection: Collected dust is discharged via hopper outlets (e.g., rotary valve, screw conveyor) for centralized recovery or disposal.

Offline Cleaning, No Re-entrainment
Each chamber operates independently. During cleaning, filtration stops—preventing dislodged dust from re-entering the clean air zone, significantly improving cleaning efficiency and emission stability.

Compartmentalized Design, Maintenance Without Shutdown
Multi-chamber structure allows one chamber to be isolated for maintenance while others continue operating—ensuring uninterrupted production.

Intelligent Control, Reliable Operation
PLC-based control system supports differential pressure, timer, or hybrid modes—with fault alarms, data logging, and remote communication (MODBUS/485).

Robust Structure, Wide Adaptability
Housing made of Q235 or Q345 steel with anti-corrosion coating; bag cages galvanized or silicone-coated—resistant to corrosion and deformation. Suitable for high temperature (≤260°C), humidity, and corrosive gases.

Modular Design, Easy Installation
Standardized modules enable quick on-site assembly, low foundation requirements, flexible configuration by airflow—suitable for new or retrofit projects.

Foundry: Dust control for medium-frequency furnaces, arc furnaces, cupolas

Metallurgy: Sinter machine, blast furnace tapping, converter secondary fumes

Building Materials: Cement mills, coal mills, dryers, crushers

Chemical: Reactor vents, powder conveying, packaging dust

Energy: Biomass boilers, waste incineration, fly ash collection in power plants

Stable Operation: Compartment + offline design ensures 24/7 continuous operation

Compliant Emissions: High-efficiency filtration and precise cleaning for long-term compliance

Energy Saving: Low pressure drop reduces fan power—saving tens of thousands annually

Easy Maintenance: Top-access bag replacement—no need to enter chamber, fast and safe

Complete Service: Selection support, installation guidance, commissioning, training, and lifelong spare parts
