Gas box pulse bag filter is a dry dust removal device that uses filter bags as filtering media, mainly used to capture particulate matter in dusty gases. It consists of multiple independent air boxes, each containing several filter bags. Compared with traditional single machine or warehouse top bag filters, the pneumatic pulse bag filter has a larger processing air volume and higher filtration efficiency, and can adapt to more complex working conditions.

Working principle

The working principle of the pneumatic pulse bag filter mainly includes two processes: bag filtration and pulse cleaning:

Bag filter: After the dusty gas enters the dust collector through the intake pipe, it first undergoes preliminary dust removal through pre-treatment devices such as cyclone dust collectors or diffusion plates. Subsequently, the gas enters the bag filtration area, and the dust is captured by the fiber layer on the surface of the bag and adheres to the outer surface of the bag. The clean gas then passes through the bag into the clean air chamber and is finally discharged through the exhaust pipe.

Pulse dust cleaning: As the dust removal process continues, the dust on the outer surface of the bag gradually accumulates, leading to an increase in bag resistance and a decrease in dust removal efficiency. At this time, the pulse cleaning system is activated, and high-pressure gas is instantly sprayed onto the bag, causing severe vibration and expansion of the bag, thereby shaking off the dust attached to the outer surface of the bag and falling into the ash hopper. After the dust cleaning process is completed, the bag will restore its original filtering performance and continue to be used for dust removal work.

Characteristics and Applications

The pneumatic pulse bag filter has the following characteristics:

Efficient filtration: able to adapt to high concentration dust environments, with large air flow and high filtration efficiency.

Automatic dust cleaning: Equipped with an advanced pulse dust cleaning system, it can automatically complete the cleaning of dust on the surface of the filter bag without affecting normal operation, ensuring long-term stable performance.

Strong adaptability: Suitable for various complex working conditions and capable of handling high concentration dust environments.

Gas box pulse bag filter is widely used in various industrial fields, such as metallurgy, building materials, chemical industry, etc., to remove dust generated in the production process, protect the environment and workers' health.
