Cartridge dust collectors can be seen in many industrial processing fields. Due to their high dust removal efficiency, small equipment size, and convenient replacement of dust filter filters, they are widely welcomed by owners. The filter cartridge dust collector is also very prone to blockage, hardening and corrosion of the dust filter cartridge during operation. This is mainly because the excessive moisture content in the dust or insufficient compressed air will affect the dust removal efficiency of the filter cartridge dust collector.
As the source of industrial dust collector equipment production and processing for more than 20 years, such as bag filter, filter cartridge filter, welding fume filter and spray tower have always been one of our main business of environmental protection. For the common problems of filter cartridge dust collectors, what are the reasons for too large or too small resistance, and how to eliminate them.
The operating resistance of the filter cartridge dust collector is too large
It is one of the more common problems that the filter cartridge dust collector equipment finds that the operating resistance is too large during the operation. If it is found that the running resistance is too large, it may be that the dust filter cartridge is blocked, or the pulse valve is not working, the poppet valve is not closed when the pulse valve is working, the pressure of the compressed air source is too low, or one or more poppet valves Disabled.
It is not difficult for those who see the dust removal filter element of the filter cartridge dust collector to find that the filter material in the middle of the dust removal filter element is folded to increase the filter area. The operating resistance of the dust collector is too large; at the same time, if the dust contains a large amount of moisture, the dust removal filter cartridge is sticky, and it is difficult to clean up the dust, which will also cause the filter cartridge dust collector to run too much resistance.
Solution: For dust with excessive moisture content, on the one hand, the temperature of the dust and flue gas should be increased; Poppet valve or cleaning controller, air system and air compressor to detect and solve problems in time.
The filter cartridge dust collector equipment found that the operating resistance was too small during the operation
If the filter cartridge dust collector equipment finds that the operating resistance is too small during the operation, it may be that the filter cartridge is damaged and damaged, the filtering wind speed is too fast, the cleaning force is too high, and the pressure measuring device is out of order.
Solution: replace the damaged filter cartridge of the dust collector; consult the manufacturer for reasonable adjustment if the filter air speed is too fast; if the cleaning force is too large, adjust the air valve force and pay attention to the angle of the blowing pipe.
