The coated filter bag filter is a kind of high-efficiency, low-energy dust removal equipment, which is widely used in the dust and exhaust gas treatment generated in various industrial production processes. Its working principle mainly includes the following aspects:
Filtration principle: The coated filter material bag filter filter uses a special coated filter material as the filter medium, when the dusty gas passes through the filter material, the dust is trapped on the surface of the filter material, so as to achieve gas-solid separation. The coated filter material has good air permeability and filtration energy, and can effectively remove fine particles.
2.Principle of ash cleaning: The coated filter material bag filter adopts the pulse jet cleaning method, and controls the injection of compressed air through the pulse valve to make the dust on the surface of the filter material fall off. Pulse jet cleaning can not only ensure the cleaning effect, but also reduce the running resistance of the equipment and prolong the service life of the filter material.
3.Structural principle: The coated filter material bag filter filter is mainly composed of a box, a filter bag, a frame, a pulse valve, a control system and other parts. The filter bag is fixed to the frame to form the filter unit. When dusty gas enters the dust collector, it is first filtered through the filter bag and then the clean gas is discharged through the exhaust pipe.
However, during the use of the coated media baghouse, the coated media membrane may be damaged. Once the membrane is damaged, it will affect the filtration effect and service life of the dust collector. In response to this situation, the following measures can be taken to deal with it:
Replace the damaged coated filter film in time: After the coated filter film is found to be damaged, it should be stopped immediately and replaced with a new coated filter film. Check the wear of other filter bags to ensure the proper operation of the entire dust collector.
2.Strengthen the maintenance and management of equipment: regularly inspect, repair and maintain the coated filter bag filter to ensure that the equipment is in good working condition. In particular, it is necessary to pay attention to the operation status of key components such as pulse valves and cylinders to prevent damage to the coated filter film due to component failure.
3.Optimize operating parameters: Reasonably adjust the working parameters of the dust collector, such as filtration wind speed, injection pressure, etc., to reduce the wear rate of the coated filter film and prolong its service life.
The coated filter bag filter has high dust removal efficiency and stability in practical applications, but it is also necessary to pay attention to the damage of the coated filter film during use, and take corresponding measures to deal with it to ensure the normal operation and service life of the equipment.
