Product Description
Four elements of the long life of a cloth bag
1. Select the suitable filter material
The filter material should be considered according to the temperature, temperature and chemical characteristics of the gas, the size, weight, shape, pecking property, dust concentration, filtration speed, ash cleaning method, discharge concentration and working system of bag type Dust Collector. Generally speaking, pulse jet Bag Filter is made of needle felt, split chamber reverse blow bag filter or mechanical vibration bag filter. (for the performance of various fabrics, see Appendix 2)
The Dust Filter Bag and frame are the main parts of the filter part. The structure, the quality of the material surface and the matching clearance are the main factors to ensure the filtering accuracy, the effect of dust cleaning and the improvement of the service life.
The filter material is divided into three structures: two dimensional filter media, three dimensional filter media and membrane filter media.
Two-dimensional filter material: a plane crossed warp and weft yarn machine weaving, the fabric porosity is large, the dust penetration rate is high, the dust layer formed in the windward face of the filter material is retained in the dust filtration process, which plays the main filtration effect, such as "729", "208" and glass fiber cloth. The glass fiber cloth can be treated with silicone oil, graphite or Teflon, which can improve the chemical corrosion resistance such as wear resistance and acid and alkali resistance.
Three dimensional filter material: in the machine woven cloth, it is inserted into loose fibers, forming a space intersecting and dense fiber layer. In the work of the filter material with load, the dust is retained inside the filter material, forming a dust bearing gradient, in the state of balance, and the dust and the filter material are intersecting to a whole. Together play the role of filtering. The dust layer on the surface of the filter material must be removed when cleaning. After the surface of the filter material is treated by singeing, calendering, coating and soaking, it has waterproof and oil proof properties, and can improve and improve the filtration efficiency and cleaning effect.
Film coated filter material: polytetrafluoroethylene is used to expand into a three-dimensional mesh structure, and the smooth and stable surface of the microporous membrane is covered with the substrate of the two-dimensional filter material of the filter material, forming a kind of microporous membrane cladding filter. In the load of the filter material, all the dust is blocked on the outer surface of the membrane, and all of them are removed after cleaning. After being coated with membrane, the filter material is widely used because of its small pore size, high air permeability, small resistance, high filtration accuracy and comprehensive chemical stability.
2. Design a reasonable structure
The structure of the bag should meet the requirements of the filter and ash cleaning of the bag type dust collector matching with it, and it is easy to install, reliable in sealing, to pursue the corresponding filter area and good filter state, easy to clear ash and to avoid wear as far as possible. It is reasonable with the related components. For example, the filter bag and the frame should be loose and fit, and the outer filter bag should be closely matched with the frame with small spacing, and the inner filter bag should consider and set up the force of the cloth bag.
