When the bag cage is in use, it is an installation fitting that can make various outer filter bags maintain a certain shape under the conditions of filtration and ash cleaning conditions. When it is used, its quality is directly related to the filtration of the filter bag to a certain extent. Ash removal effect and service life.
Due to the fact that most of the outer filter round bags use elastic expander rings and flower plate fixed seals, the aperture of the flower plate aperture is inconsistent with the bag opening, which easily causes the following problems:
1. The board aperture is too small and the installation is difficult. The installer will damage the bag opening by tapping the elastic expansion ring with a heavy object.
2. The flower plate hole is too large, the filter bag and the bag cage will cause the phenomenon of “bag falling out”, and the bag mouth is not dense enough, the bag mouth is easy to leak ash, and the dust removal efficiency cannot be guaranteed.
3. Non-standard filter bag installation.
During the process of installation, the filter bag must be directly installed with a filter bag. Once the plate hole with its burr is easy to scratch the filter surface, it can effectively reduce the filter bag filter performance in use. When it is used, especially with the membrane filter bag, the filter performance of the filter bag will be greatly reduced after the surface membrane is damaged.
Filter bags need to use the entire room to install the filter bag, then install the bag cage method, and the installation of the filter can take timely protective measures. The installer can’t avoid stepping on the filter bag mouth during handling and installation work, causing deformation of the bag mouth. After the bag mouth is deformed, the bag mouth and the flower plate hole cannot be completely closed and there is a gap. After the operation, dust leakage or even bag falling occurs.
With the development of baghouses to larger and longer bags, filter bags and bag cages are getting longer and longer, and colliding the end of filter bags with each other is very common. The bottom of the bag cage is disorderly and uneven, and some of the filter bag body and the bottom of the bag rub against each other. After the filter bag is put into operation, it will cause high damage rate and shorten the service life. The reason for this phenomenon is:
1. The flower board is uneven, with a certain degree of inclination or unevenness, and the bag cage is skewed toward unevenness.
2. The bag cage is not vertical, especially if the multi-section bag cage is not aligned with the center of the bag, causing the bag cage to tilt.
3. The bag cage was not adjusted after installation.
