Dust bag selection of the first condition is the bag filter cleaning method. It can first determine the dust bag is the media, weaving felt or compression mats and so on. As for the detailed specifications of the dust bag, according to other filter conditions for further consideration.
1, vibration cleaning.
This kind of cleaning method is characterized by the kinetic energy applied to the dust layer than the pulse injection, backflush type is small, is low energy type cleaning, so suitable for fabric dust filter bag. The vibration wave of the soft soft fabric is better.
2, anti-blowing (anti-suction air bag) cleaning.
This kind of cleaning method usually uses fabric dust bag, but it is also possible to use a felt having a relatively small cloth weight, a softness and a small variation in size. Which use glass fiber dust bag most, and for the majority of large bag filter. Dust filter bag lifting, sewing and other processes have a certain requirement, such as attention to the dust bag life of a greater degree of impact.
3, pulse jet cleaning.
This cleaning method is applied to the dust layer of the ash is the highest kinetic energy, is a typical way outside the filter cleaning. Fine dust force is very strong, dust bag yarn inside the residual dust residue is relatively small, the use of dust bag is generally felt or needle felt. In the pulse of the role of dust filter bag will instantly become very large, resulting in a lot of stress, it must use strong anti-tension filter. Dust bag and skeleton often friction, and thus to use a good wear resistance dust bag.
4, gas ring jet cleaning.
Because this way the cleaning performance is quite good, requiring dust bag has a good rigidity, small pores, and good wear resistance, so that in the jet air ring up and down when moving, dust bag does not change, not fluff. So limited use of felt or needle felt. But also requires thick, high-density felt.
5, pulsating backflush cleaning.
This method is applied to the dust in the kinetic energy of high energy and low kinetic energy in the middle, this cleaning requires dust filter bag filter with flexibility, and also requires a certain degree of stiffness.
It is advisable to use satin and twill fabric when using fabric dust bag. However, it is advisable to use needle press felt from dust removal efficiency, filtration speed, anti-wear strength of skeleton, 600g / m2 of needle felt. Rarely use woven fabrics, if necessary, should be a variety of surface processing.
6, anti-blowing - vibration cleaning.
The cleaning power applied to the dust layer is low energy. The initial use of fabric dust bag. At present, the majority of needle felt, the main reason is to improve the filtration rate, needle felt requirements for the weight of 280 / ㎡ ~ 350g / ㎡, the thickness of 1.0mm ~ 1.3mm, its permeability is better.
In the sewing and installation of the dust bag, we usually tighten the dust filter bag and prevent the size of the stretch in the filter, because when the dust bag spreads up to about 2%, the cleaning effect deteriorates, so in the dust bag ( Filter bag) stereotypes processing, will consider the technical conditions to prevent the expansion of the bag.
