The high dust removal efficiency of the bag filter is inseparable from its dust removal mechanism. When the dust-containing gas is taken from the lower intake pipe of the dust collector and enters the ash hopper through the deflector, Due to the collision of the deflector and the reduction of the gas velocity, The coarse dust will fall into the hopper, and the remaining fine particles will enter the filter bag chamber with the gas. Due to the inertia, diffusion, blocking, hooking, static electricity and the like of the filter fiber and the fabric, the dust is retained in the filter bag, and the purified gas escapes out of the bag and is discharged through the exhaust pipe. The ash on the filter bag is removed by a gas backwashing method, and the removed dust is discharged to the ash hopper, and discharged to the ash conveying device through the double-layer ash discharging valve. The ash on the filter bag can also be removed by blowing a pulsed airflow to achieve the purpose of cleaning, and the removed dust is discharged by the ash discharge device.
The high dust removal efficiency of the bag filter is also inseparable from the filter material. The performance and quality of the filter material are directly related to the performance of the bag filter and the length of the service life. The filter material is the main material for making filter bags. Its performance and quality promote the advancement of bag dust removal technology, affecting its application range and service life.
