Which dust bag is more suitable for dust removal equipment?
1. Dust removal equipment of chamber back blowing type
This kind of dust removal equipment belongs to the type of low kinetic energy dust removal. Thin dust removal bags can be selected, such as 729, mp922, etc., which are soft in texture, easy to deform and stable in size. There is no difference in the selection of dedusting cloth bag for indoor and outdoor reverse blowing dust dedusting equipment. Satin (or twill) woven dedusting cloth bag is preferred for large and medium-sized deduster, and thin needle felt dedusting cloth bag strengthened by base cloth can also be selected for special occasions. The thin needle felt dust bag with good wear resistance and air permeability is preferred for small dust remover. The unit area mass is 350-400g / m2, and the double weft or double fabric dust bag can also be used.
2. Mechanical vibration dust removal equipment
This kind of dust removal equipment is characterized by small power and more times of vibrating dust layer. In order to make the energy easy to spread and ensure sufficient vibrating force on the filter surface, thin and smooth dust removal cloth bag with soft texture should be selected. For example, for chemical fiber satin or twill fabrics, the thickness is 0.3-0.7mm, the mass per unit area is 300-350g / m2, and the filtration speed is 0.6-1.0m/min, which can be increased to 1.0-1.5m/min for small dust remover units.
3. Dust removal equipment of pulse injection type
The selection principle of dust removal cloth bag of this kind of dust removal equipment is basically the same as that of the chamber back blow type dust remover, with satin (or twill) woven dust removal cloth bag as the main one. At present, thin needle felt has been gradually used.
4. Nozzle back blowing dust removal equipment
Rotary back blowing dust removal equipment and reciprocating back blowing dust removal equipment mainly adopt the form of outer filter flat bag with dust removal frame, which is compact in structure. Such dust removal equipment requires the selection of relatively soft, stable in structure and good in wear resistance. Medium thickness needled felt dust removal bag is preferred, with unit area mass of 350-500g / m2.
Dust removal equipment is a kind of widely used dust removal equipment, and dust bag is its core component. The selection of dust bag is very important for dust removal equipment. From the initial use of foreign dust bags to the gradual use of domestic dust bags to replace, witnessed the development of domestic dust bags.
