The relationship between filter bags and filter cages

1. The performance relationship between the dust filter bag and the dust filter cages It is necessary to be reasonable when choosing dust filter bags and dust filter cages. The cage is based on the cooperation between the dust filter bag cage and the dust filter bag filter material. In order to prolong the service life of filter bags, the smaller the space between them, the better. Because the relative space between the keel and the filter material is reduced, the contact between the two can be limited, thereby reducing friction. However, on the other hand, in order to ensure the cleaning effect, the requirements for the two are completely opposite, and different working environments require different cage materials. In environments with high temperature and corrosive gases, higher grade materials are required. It is used to prevent the dust filter cage from being corroded, which will lead to damage to the filter material and failure. For example: in the working environment with more acid gas, stainless steel dust removal skeleton may be the choice. Ordinary dust filter cage, such as galvanized dust filter cage, may be corroded in the presence of acid and alkali.

2. the quality relationship between the dust filter bag and the dust filter bag cage. Since the dust filter cage is always in contact with the filter material, the impact on the filter material is very important! A suitable dust filter cage will help the use effect and life cycle of the dust removal filter bag. The initial surface properties of the dust filter cage are critical. The surface of the dust filter cage should be smooth and flat, which is the most basic requirement. The ability to maintain the surface properties of the cage is an important basis for measuring the quality of the cage. The burrs and bumps on the surface of the dust filter cage will directly lead to the abnormal failure of the cage.

 3. The relationship between the dust bag and the size of the cage. The processing of the size of the dust removal frame is guaranteed. The guarantee of the size of the dust removal frame includes the verticality and straightness of the frame. It is not difficult to imagine that the curved and inclined keel may lead to insufficient length of the filter bags and abnormal contact between the filter bags and between the filter bags and the box. For round cages, the uniformity in the perimeter direction is also very important. Since the keel ensures its verticality by its own weight, the guarantee and inspection of dimensions are often not simple.
