China DMC Series Pulse Bag Dust Collector - High-Efficiency Dust Control Solutions from Trusted 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.
Characteristic and feature of DMC series pulse bag dust collector
- (1) 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;
- (2) There is no need to spray pipe in the bag room, and it is convenient to change the bag outside the machine;
- (3) Embedded elastic bag mouth, good sealing performance;
- (4) The number of pulse valves is small, the cleaning strength is large, and the action is rapid;
- (5) The machine adopts microcomputer automatic control, each parameter is easy to adjust, can achieve no post work;
- (6) filter bag service life of more than two years;
- (7) Easy to achieve isolation maintenance.

Frequently Asked Questions
How does the DMC series pulse bag dust collector work?
Dust-laden air enters the dust collector, where large particles drop into the ash hopper due to gravity. Fine dust is captured by the outer surface of the filter bags, and clean air is discharged. A microcomputer controller periodically triggers electromagnetic pulse valves to release high-pressure air, expanding the bags and shaking off the dust into the hopper.
Does the DMC series dust collector require pre-dust removal equipment?
No, it does not. The DMC series pulse bag dust collector can handle high dust concentrations of up to 1000mg/m³ in a single stage, keeping emissions under 50mg/m³ while maintaining a simple and efficient process.
What is the average service life of the filter bags?
The filter bags in the DMC series are designed for high durability and have a service life of more than two years under normal operating conditions.
How convenient is maintenance and bag replacement?
Bag replacement is highly convenient as it is performed outside the machine, eliminating the need to enter the bag room. Additionally, the system easily supports isolation maintenance for minimal operational downtime.
How is the cleaning system controlled?
The machine utilizes a microcomputer automatic control system. All parameters are easy to adjust, allowing for reliable, unmanned operation.
