• Working principle of cloth bag dust collector in mine
  

The mine cloth bag dust collector is composed of upper box, middle box, ash bucket, bracket, filter bag assembly, reverse blowing and flying mechanism, ash discharge valve, etc.

The design concept of large air volume and low wind speed is adopted by the cloth bag dust collector in mine.

When the dust-bearing gas enters the ash hopper through the guide plate, the coarse dust falls into the ash hopper due to the collision of the guide plate and the reduction of gas velocity.

The rest of the fine dust particles enter the filter bag room with the gas. Due to the inertia, diffusion and other effects of the filter material fiber and fabric, the dust is blocked outside the filter bag, and the purified gas escapes outside the bag and is discharged through the exhaust pipe.

◆ Intensive cleaning: The use of pulse jet device, has strong cleaning capacity, in 0.2 ~ 0.3MPa jet pressure, all kinds of dust with strong adhesion can get good cleaning effect.

◆ Low equipment resistance: running resistance can be stable in the range of 900 ~ 1500Pa for a long time, obviously lower than other types of bag dust collector.

◆ High dust removal efficiency: under normal circumstances, dust discharge concentration is less than 50mg/Nm3, in some special requirements of the occasion, can be less than 10mg/Nm3.

◆ Easy bag changing: the filter bag is embedded by the elastic swelling ring of the bag mouth and the flower plate hole, with good sealing effect, convenient disassembly and assembly, reducing the workload of bag changing and the contact between maintenance personnel and dust.

◆ Online/offline cleaning mode: according to the operating conditions and user requirements, the equipment can achieve online cleaning or offline cleaning two different ways.
