Comparison of cartridge dust collector and bag filter

Cartridge dust collector and bag filter are two kinds of common used dust equipment, which characteristics they have, and what are the advantages of each, we do the following points to analyze:

A. The filter material
1. Cartridge of cartridge dust collector was folded to form a cylinder arrangement, no skeleton, short.
2. Bag filter use a bag with sewn into soft filter, to set into the skeleton, which made from cold drawn wire, vertical bag vertical.

B. The filtering principle
1. Spacing between the filter of cartridge filter is big, the dust is not in-depth filter, cleaning completely, no secondary pollution.
2. Bag dust collector layout is dense, dust is in-depth filter, by the outer surface of the filter material to establish dust layer maintenance dust removal efficiency.

C. The main performance
1. Filter-type dust collectors have anti-condensation, good ventilation, dust removal efficiency, stable, low resistance, blowback force, uniform, good effect, cover small space.
2. Bag filters have rough filter, easy to stick dust, dust removal efficiency, stable, easy to blowback bag length is not uniform, larger, easy to wear between the bag and the skeleton.

D. The economy
1. Cartridge dust collector light weight, small size, compressed air consumption, low requirements, saving civil and air equipment investment.
2. Bag filter volume larger, heavy weight, compressed air consumption, high pressure and high investment in civil and air equipment, high power consumption.

E. The respective advantages
1. Cartridge dust collector advantages:
The filter cartridge adopts the new filter material (waterproof, anti-abrasion and anti-corrosion), new structure (the rigid filter material is folded and arranged, no steel skeleton, no filter abrasion), new theory (surface filtration instead of deep filter dust, and filter inside). Its advantages are as follows:
1) Filter dust collector surface dust removal efficiency is much higher than the old dust collector, greatly reducing the emissions of harmful substances, air purification indicators reach the world advanced level, complete changed the old-style precipitator cannot meet the requirements of backwardness status.
2) The cartridge filter dust collector without filter wear phenomenon, the body has no moving parts, long-term use without maintenance (even if the filter is also very easy to replace the filter) to avoid the old-style filter constantly changing filter troubles, the provincial money saving time and effort and no secondary pollution.
3) Cartridge-type dust collector of its size and weight is much smaller than the same specifications of the old dust collector, saving civil construction space and civil construction load, saving significant investment in infrastructure.
4) Cartridge filter has dust resistance, consumption of compressed air is small, no maintenance workload. Compared to all types of old-style dust collector, this type dust collector is more energy saving, saving no less than 30%.

2 .the advantages of bag filter:
1) It has the characteristics of simple operation, continuous ash cleaning, stable resistance, high filtering speed, no internal moving parts, simple structure and so on. It is a high performance bag filter.

2) High dust removal efficiency, can collect more than 0.1UM of dust, so that dust purification to 15mg / m3 or even the following gas.
3) Less ancillary equipment, investment, technical requirements are not high electrostatic precipitator.
