 Dust Category: 
 According to the principle role of dust into the following five categories: 
 (1) mechanical forces, including gravity dust filter, inertial dust collector, centrifugal dust collector and so on. 
 (2) washing bath-type dust collector including dust, foam dust, dust Venturi tube, the water membrane filter and so on. 
 (3) filter and bag filter dust, including dust and other particulate layer 
 (4) electrostatic precipitator. 
 (5) magnetic dust. 
 Now more and more industries are using the bag filter. (Fabric filter) 
 Fabric filter technology: 
 Definition: the use of bag filter dust removal technology. 
 Bag material: natural fibers, chemical fibers, glass fibers, metal fibers. 
 Forms: gas from the bag outside to inside, the outer surface of dust in the bag 
 Gas from the bag inside to outside, the inner surface of dust in the bag
