1. By adopting the technique of intermittent pulse blowing for dust cleaning in separate rooms, the shortcomings of conventional pulse dust collectors and back blowing dust collectors in separate rooms are overcome. The dust cleaning ability is strong, the dust removal efficiency is high, the emission concentration is low, the air leakage rate is small, the energy consumption is low, the steel consumption is low, the footprint is small, the operation is stable and reliable, and the economic benefits are good. Suitable for the purification of dusty gases and material recovery in metallurgy, building materials, cement, machinery, chemical, power, and light industry industries.

2. Due to the use of split chamber air stop pulse spraying for thorough cleaning, the cleaning cycle is extended and the energy consumption for cleaning is reduced, resulting in a significant decrease in compressed air consumption. At the same time, the fatigue level of the filter bag and pulse valve is correspondingly reduced, thereby doubling the service life of the filter bag and valve plate.

3. The maintenance and bag replacement can be carried out in separate rooms without stopping the system fan and under normal operating conditions of the system. The filter bag mouth adopts an elastic expansion ring, which has good sealing performance and is firm and reliable. The filter bag keel adopts a polygonal shape, which reduces the friction between the bag and the keel, extends the life of the bag, and is easy to unload.

4. Adopting the upper bag extraction method, after extracting the skeleton during bag replacement, the dirty bags are put into the lower ash hopper of the box and removed from the manhole, improving the operating conditions for bag replacement.

5. The box adopts an airtight design with good sealing performance. The inspection door uses excellent sealing materials, and during the manufacturing process, kerosene is used for leak detection, resulting in a very low air leakage rate.

6. The layout of the inlet and outlet air ducts is compact, with low airflow resistance.
