Pulse jet dust collector
Dusty gas enters the dust collector through the inlet, impacts the baffles and plates, and then changes direction to flow into the hopper. Coarse dust particles fall directly into the hopper due to inertia. Then the airflow turns upward and passes through the filter bags. Dust is collected on the outer surface of the filter bags. The purified gas enters the clean gas chamber and is discharged from the outlet. As the dust on the filter bags increases, the resistance increases. When it exceeds a certain range, the pulse controller triggers the control valve to open the pulse valve, and the compressed air in the air bag is sprayed into the filter bags through the blowpipe, causing the filter bags to expand rapidly, and the dust falls off into the hopper and is discharged through the ash discharge system.

Details Description
Dusty gas enters the dust collector through the inlet, impacting the baffle plates and deflectors, and then turning to flow into the hopper. Large dust particles fall directly into the hopper due to inertia. Then the airflow turns upward, passing through the filter bags. Dust is collected on the outer surface of the filter bags. The purified gas enters the clean gas chamber and is discharged from the outlet. As the dust on the filter bags increases, the resistance increases. When it exceeds a certain range, the pulse controller triggers the control valve to open the pulse valve, and the compressed air in the air bag is sprayed into the filter bags through the blowpipe, causing the filter bags to expand rapidly, and the dust falls off into the hopper and is discharged through the ash discharge system.
Structural Composition
Housing: Includes the shell, filter bags, inspection doors, filter bag hoops, and baffles. It is the main part of the dust collector, used to house filter bags and other components. Exhaust system: Consists of a fan, motor, and the fan's transmission device, responsible for discharging the purified gas from the dust collector.
Pulse Jetting System: Consists of a pulse controller, control valve, pulse valve, jet pipe, and compressed air bag, etc. It is the key component for pulse cleaning.
Inlet and Ash Discharge Section: The inlet section allows dusty gas to enter the dust collector evenly; the ash discharge section includes the hopper and ash discharge device, used to collect and discharge dust.
Features
Powerful Dust Removal Capability: Adopts compartmentalized stop-wind pulse jetting dust removal technology. A single jetting can thoroughly clean the dust, extending the cleaning cycle and reducing energy consumption.
High Dust Removal Efficiency: Effectively captures dust particles of various sizes. The dust removal efficiency usually reaches over 99%, with low emission concentration.
Stable and Reliable Operation: The advanced control system achieves automated operation, reducing manual intervention. The equipment operates stably, with low air leakage and low energy consumption.
Easy Maintenance: Inspection and bag replacement can be performed in compartments without shutting down the system fan. The system operates normally, and filter bag replacement is simple.
Application Areas
Metallurgy Industry: Used for dust removal in calcium carbide furnaces, ferroalloy electric furnaces, and steel plant flue gas.
Power Industry: Can handle dust removal in coal-fired power plant boilers and small boilers, and garbage incineration furnace flue gas dust removal.
Building Materials Industry: Dust removal at the kiln head and kiln tail of cement plant rotary kilns, and carbon black plant tail gas dust removal.
Chemical Industry: Purification of dusty gas generated during various chemical production processes.
