Bag Dust Collector

① High dust removal efficiency, especially for fine powder, which can generally reach more than 99%;

② Strong adaptability, it can handle different types of particulate pollutants (including high specific resistance dust that is difficult to handle with electrostatic precipitators). It can be designed as a small bag filter or a large bag filter according to the gas processing volume;

③The operation flexibility is large, and when the dust concentration of the inlet gas changes greatly, it will have little impact on the dust removal efficiency. In addition, the dust removal efficiency also has a certain stability to changes in air flow velocity;

④Simple structure, flexible use, easy to recycle dry materials, and no sludge treatment.

The application of bag dust collectors is mainly limited by the operating performance of the filter cloth such as temperature resistance and corrosion resistance. Generally, the operating temperature of filter cloth is less than 300°C. Bag dust collectors are not suitable for removing dust particles with strong adhesiveness and hygroscopicity. , especially the flue gas temperature cannot be lower than the dew point temperature, otherwise frost will form on the filter cloth, causing the paste bag to be blocked, thus affecting the normal operation of the bag dust collector.

Product Details

Bag dust collector is a dry dust filtering device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and uses the filtration effect of fiber fabric to filter dust-containing gas. When the dust-containing gas enters the bag dust collector, the dust with large particles and heavy specific gravity will be removed due to gravity. It will settle down and fall into the ash hopper. When the gas containing fine dust passes through the filter material, the dust is blocked, thus the gas can be purified.

1. Shell: The shell is the main part of the dust collector, usually in a circular, square or diamond shape. It has good sealing and stability, ensuring the normal operation of the dust collector.

2. Filter bag: The filter bag is the core component of the dust collector, usually made of polyester fiber, polypropylene fiber and other materials. It has high strength, high temperature resistance, corrosion resistance and other properties, and can effectively capture dust.

3. Ash hopper: The ash hopper is a device for collecting dust in the dust collector, usually located at the bottom of the dust collector. It has good sealing and stability, ensuring dust collection and transportation.

4. Pulse valve: The pulse valve is an important component in the dust collector for controlling air flow. It is usually installed at the inlet and outlet of the dust collector. It can inject gas regularly or quantitatively according to program control requirements to achieve the purpose of dust cleaning.

5. Injection device: The injection device is an important component for injecting gas in the dust collector, and is usually located at the outlet of the pulse valve. It can blow gas to the inner surface of the filter bag at a certain pressure and flow rate to achieve the purpose of dust cleaning.

6. Control system: The control system is an important component in the dust collector that controls the operation of the entire equipment. It is usually composed of PLC, relays and other control components. It can control various components regularly or quantitatively according to program control requirements to ensure the normal operation of the dust collector.

Application scope

Manufacturing Plant, Machinery Repair Shops, Farms, Retail, Printing Shops, Construction works , Energy & Mining, Vibrating sieve, mixing station

Principle: Dust enters the cylinder through the air inlet. Due to the principle of inertia or the dust absorption of the induced draft fan, dust is adsorbed on the bag. As time goes on, the dust of the bag becomes more and more, which increases and compresses the air to the bag, thereby increasing the resistance of the bag (filter), resulting in a gradual reduction of the air handling capacity. For normal work, it is necessary to clean the bag and dust. When the pulse controller triggers the control valves sequentially and opens the pulse valves, the compressed air in the air box is injected into the corresponding cloth bags through the venturi tubes, and the cloth bags expand rapidly in an instant, so that the dust accumulated on the surface of the cloth bags (filter cartridges) falls off and the cloth bags are regenerated. Dust falls into the mixing tank or the ash storage room.

Suitable for environment, large-scale working condition enterprises. Mixing station industry, flour storage industry, etc. If there are strict requirements for the environment, you can use this. Its excellent ash cleaning system and long service life. It is its biggest characteristic. In addition, it is easy to install and maintain.
