Pleated dust bag

Frequently Asked Questions about Pleated Dust Bag Dedusting Technology

1、Price of pleated dust bag and its matching cage?

The price will be adjusted upward because of the increase of filtering area and cage material. You can consider the comprehensive cost of the dust collector's manufacturing, transport, installation, maintenance and energy consumption and other aspects of the comprehensive cost.

2、Does the gap between the dust bag increase compared with the normal dust bag?

For the transformation of traditional bag filter, the dust bag interval can be the same as normal round bag. For the new design of dust collector, in principle, the larger the interval, the better, but the spacing will increase the size of the dust collector will increase the cost, so the general design will take an optimised spacing.

3、What is the requirement of blowing pressure? Is it easy to clean the dust?

The blowing pressure is related to the air-to-cloth ratio. The pleated dust bag is used in low and medium pressure. If the dust bag with ordinary valve 2.5 metres, 0.3-0.5MPa can be, ordinary round bag high-pressure blowing design is generally high-pressure 0.5-0.7MPa, used in the waveform dust bag will not have a problem, but no . The inner diameter of pleated dust bag is very small, and the same as the round bag than, for the irregular shape, the pulse air flow does not need to overcome the negative pressure can be shocked off the filter cake, complete the dust removal, pleated bag in the middle of the part of the loose, blowing vibration amplitude is larger, easy to clear the dust. In addition, the pleats are shallow and the space in the middle is relatively large, which will not cause the lumps like the cartridge clearing.

4、What is the difference between air and cloth ratio?

Pleated dust bag ratio in principle can be designed according to the ordinary round bag, that is, 1.0-1.2m/min. 5, energy consumption can be saved, through which aspects of saving? In the same situation, the pleated dust bag cleaning effect will be better than ordinary round bag, the same air to cloth ratio, the compressed air consumption will be reduced, the blowing frequency will be reduced (blowing interval is extended), the life of the blowing valve will be extended, if it is compared with the same number of round bag to deal with the same amount of air volume, the fan's energy consumption will be reduced by 40-50% or so (this is the same as the design of the air to cloth ratio) ----- This is the case in the use of waveform dust bag instead of round bag This is in the case of using waveform dust bag instead of round bag (i.e. the existing dust collector transformation).

5、Is there any change in the shell of the dust collector? Is there any saving in material and volume?

If the new design of dust collector adopts the same air-to-cloth ratio as that of the round bag, the cross-sectional area of the box can be reduced by 85%, so the volume can be reduced by 85%, so the material can be saved in the same way. The number of blowpipes and pulse valves are reduced accordingly. It is recommended to design with a slightly lower air-to-cloth ratio, e.g. increase the filtering area by 50% instead of 80%, so that the customer will experience a longer bag life and a better operating effect.
