The correct installation of filter bags is of great significance for the service life of bag filters. If the filter bags are not installed correctly, it may lead to filter bag wear and affect the dust removal efficiency of bag filters. Filter bags are usually cylindrical and vertically suspended in the bag filter. When installing the filter bag, it is placed on the cage bone and then hung downwards in the bag filter through the flower plate hole. During the installation of filter bags, attention should be paid to:
- All filter bag seams are facing in the same direction, which can help effectively troubleshoot when the filter bag is worn out.
- It is necessary to check whether the edge of the filter bag with flanges or cuffs folded at the top of the supporting cage bone is smooth to prevent leakage or wear of the filter bag.
- The cloth bag should not be too large than the cage bone to avoid excessive wear and tear between bags and between bags and cage bones due to the loose and unsupported cloth bag, which will reduce its service life. At the same time, the cloth bag should not be smaller than the cage bone to avoid excessive stretching of the cloth bag, which may shorten the service life of the filter bag due to excessive pressure during ash cleaning. The appropriate and uniform tension of the filter bag should be ensured to eliminate the potential damage to the bag during the operation of the bag filter.
When installing filter bags, it is necessary to ensure that there is appropriate spacing between the filter bags. Excessive spacing can cause waste and increase investment costs; If the spacing is too small, it will cause friction damage between the filter bags during the ash cleaning process.
The 5 filter bags and cage bones should be hung vertically on the bag filter to avoid gaps and increased operating costs caused by wear and tear between the bag and the flower board.
During the installation process, the cage bones should be inspected, and the surface of the cage bones should be smooth, without unevenness or burrs.
