I want to choose a suitable dust removal framework; First, it is necessary to understand the product types of dust removal skeletons
One Dust removal skeleton, also known as dust removal bag cage, is a component of bag filter.
1. Round bag type (outer filter bag)
2. Round bag spring type (external filter type)
3. Flat bag type (external filter type) (elliptical, diamond shaped)
4. Envelope type
5. Multi section frame (elliptical multi section frame, circular bag type multi section frame (plug-in, chuck type))
6. Finished frame (frame with Venturi tube, frame packaged in plastic bags or iron frames, neatly arranged diamond frame)
II Understand the external treatment of the dust removal skeleton and the temperature requirements of the usage environment.
Dust removal skeletons are generally treated with spray coating, silicon coating, and zinc coating. These three treatment methods are suitable for different working conditions and temperatures. Spray coating dust removal skeletons are mainly used in normal temperature (0-130/140-160 ℃ range) working conditions, while silicon dust removal skeletons can be used in working conditions around 0-270/280 ℃; The temperature tolerance of galvanized dust removal skeleton and silicon skeleton is roughly the same.
III Dust cleaning methods, bag filters with different cleaning methods require different structures of dust removal skeletons due to differences in cleaning energy and filter bag deformation characteristics.
4 According to the welding process, the welding should be firm without burrs, bumps, peeling, leakage, or virtual welding rate less than 1%, and the open welding points should not be adjacent.
Five Check the size, diameter tolerance: circular ≤ -3%, perimeter tolerance: trapezoidal or flat ≤ -1.5%, length tolerance ≤ -1%.
