Precision processing of the cell plate

The specifications of the fiberglass-coated powder filter bag used in the low-pressure long bag pulse bag filter are basically 5 to 7 m in length. As the bags are longer, the distance between the bags and the distance between the bag and the housing wallboard should ensure that the filter bags do not touch each other. Of course, a greater distance is always good, but if the size is too large, the carapace volume will be too large and the investment will increase. The processing accuracy of the cell plate will directly affect the verticality of the filter bag and the concentricity of the nozzle.

Therefore, processing requirements have three main aspects for quality control:

The spacing of the holes in the cell plate is guaranteed to be controlled within 1 mm, and CNC plasma cutting is required during processing to ensure accuracy.

The deformation of the cell plate must be controlled within 1/1000. This requires at least a 6 mm thick steel plate and some reinforcement to ensure rigidity. At the same time, ensure that the welding deformation is controlled within the minimum range in the welding process.

The flatness of the cell plate: must be controlled within 2 mm/square meter.

All these regulations are to ensure that the filter bag reduces collisions.
