DMC Series Low Pressure Pulse Bag Filter
Powder Dedusting Equipment
Application B |
Overview:
The DMC pulse jet baghouse dust collector is a dust removal device characterized by high dust removal efficiency, stable operation, reliable performance, and convenient maintenance. It can be widely used in dust removal systems across various industries such as metallurgy, machinery, chemical, power, and building materials. This equipment has the following main features:
- The dust collector adopts a high-efficiency, low-consumption pulse jet cleaning device, achieving low-pressure, short-pulse cleaning technology;
- The filter bags are firmly fixed and easy to install and remove. The filter bags are embedded in the tube sheet with elastic expansion rings, completely eliminating dust leakage. Filter bag installation and removal are convenient, and personnel contact with the filter bags is brief and pollution-free;
- Filter bags can be extended to 6 meters or longer, significantly exceeding the commonly accepted limit for pulse jet dust collector bag length, while maintaining excellent dust removal efficiency; It has a small footprint. Single-row or double-row combinations can be designed according to the air volume and site location;
- The dust collector itself has no transmission components, requiring only routine inspections during operation, with virtually no maintenance.

Structure and Working Principle:
The DMC pulse jet baghouse dust collector mainly consists of a dust hopper, a middle chamber, an upper chamber, a pulse-jet cleaning device, and a pulse controller.
Dust-laden gas enters the lower part of the middle chamber. In the pre-dust removal chamber formed by the baffle plate, large dust particles fall into the dust hopper due to inertia. The dust-laden gas rises along the baffle plate to the filter bags, where the dust is trapped on the outer surface of the filter bags. Clean gas enters the bags and exits through the bag openings into the upper chamber. As the filtration time increases, the dust layer on the filter bags thickens, and the resistance of the dust collector continuously increases. When the resistance reaches a certain value, the cleaning device begins cleaning under the control of the pulse controller. Cleaning control can be timed or pressure-controlled, and can be selected according to production needs. During dust removal, compressed air is sequentially injected through pulse valves in a very short time, and then sprayed onto the filter bags through nozzles on the blowpipes. The acceleration caused by the expansion of the filter bags and the reverse airflow cause dust adhering to the outer surface of the filter bags to detach and fall into the ash hopper. The dust is then discharged through the ash discharge valve. After the blowing is completed, the filter bags immediately return to their filtering state. Under the control of the controller, periodic cleaning is performed according to certain requirements to ensure the dust collector always maintains good working condition.
Application Fields:
DMC dust collectors are widely used in dust removal in industries such as foundry, ceramics, glass, refractory materials, cement building materials, grinding wheel manufacturing, chemical products, and machining. This product effectively removes heavy metal shavings, foundry sand (e.g., from lathes, grinding wheels, polishing machines, milling machines, etc.), medium-weight powders such as bakelite powder, plastic powder, ceramic powder, gypsum powder, asbestos powder, carbon powder, and pigments, as well as lighter non-fibrous dust. The dust removal efficiency of this unit is greater than 99.5%. DMC baghouse dust collectors are small, highly efficient on-site dust collection devices suitable for various independent dust-generating points. They are flexible and convenient, collecting and treating dust on-site, effectively ensuring air cleanliness. |
