China DMC Series Pulse Bag Dust Collector - Energy-Saving Industrial Dust Collection Solutions from Reliable Suppliers & Factory
Working Principle
Dust-laden air enters the next ash bucket by fan powered via the inlet, then speed dips, large weight dust particles fall into the ash bucket, fine dust into the cabinet with the airflow, and out of the discharge outlet after the purification treatment by the sieve of the filter bag. The dust which separated outer of the surface of the filter bag makes the resistance increases gradually, this time the controller send up signal according to the set resistance range, electromagnetic pulse valve is open, the high-pressure air which in the air bag spray quickly, through the Venturi tube several times in the first wind-induced ambient air into the filter bag, so the filter bag instant expansion, and the dust is shaken off and falling into the dust hopper.
There is no need for pre-dust removal equipment, which can deal with the dust of up to 1000mg/m3 at one time, and the emission is less than 50mg/m3, and the process is simple;
There is no need to spray pipe in the bag room, and it is convenient to change the bag outside the machine;
Embedded elastic bag mouth, good sealing performance;
The number of pulse valves is small, the cleaning strength is large, and the action is rapid;
The machine adopts microcomputer automatic control, each parameter is easy to adjust, can achieve no post work;
Filter bag service life of more than two years;
Easy to achieve isolation maintenance.

Frequently Asked Questions (FAQ)
Q. How does the DMC series pulse bag dust collector filter fine dust?
Dust-laden air enters the ash bucket where larger particles drop down due to gravity. The remaining fine dust is carried into the cabinet by airflow and filtered through the sieve of the filter bag, allowing clean air to exit through the discharge outlet.
Q. What is the dust handling capacity and emission level of this dust collector?
The DMC series pulse bag dust collector can handle high dust concentrations of up to 1000mg/m³ at one time without needing pre-dust removal equipment. It reduces emissions to less than 50mg/m³.
Q. How long do the filter bags last and how are they replaced?
The filter bags have a service life of more than two years. They feature an embedded elastic bag mouth for excellent sealing, and they can be easily replaced outside the machine without needing spray pipes in the bag room.
Q. Does the DMC series pulse bag dust collector support automatic control?
Yes, the machine adopts microcomputer automatic control. Each parameter is easily adjustable, allowing for efficient operation without requiring dedicated post-work monitoring.
Q. What are the specifications of the filtering bags used in the DMC series?
Depending on the model, the filtering bag specifications are either φ130×2000 mm (for models DMC-36 up to DMC-320) or φ130×2500 mm (for larger models like DMC-520, DMC-736, and DMC-900).
