The structural types of dust collector bags are divided into flat bags (trapezoid and flat) and round bags (cylindrical) according to the shape of the dust collector bag.
According to the air inlet and outlet methods, it is divided into bottom air inlet and top air outlet, long air inlet and bottom air outlet, and direct flow type (only limited to plate-shaped flat bags).
According to the bag filtration method, it is divided into external filter type and internal filter type. Fibers used for filter materials include cotton fiber, wool fiber and glass fiber. Filter materials woven from different fibers have different properties. Commonly used filter materials include polyester velvet cloth. The use temperature of dust collector bags generally does not exceed ℃. The use temperature of glass fiber filter bags treated with silicone resin generally does not exceed ℃. Cotton wool fabrics are generally suitable for non-corrosive temperatures below ℃. dust gas.
The advantages of dust removal bags are
high dust removal efficiency, which can capture fine dust with a particle size larger than one meter, and the dust removal efficiency can reach above.
Flexible in use, the air volume handled by the dust collector bag can range from hundreds of cubic meters per hour to hundreds of thousands of cubic meters per hour. It can be used as a small unit directly installed indoors, near the machine tool, or it can be made into a large dust removal room, that is, Bag room.
The structure is relatively simple, the operation is relatively stable, the initial investment is small, and maintenance is convenient.
The currently commonly used dust cleaning methods include gas cleaning. Gas cleaning relies on high-pressure gas or external atmosphere to backflush the dust collector bag to remove dust accumulation on the filter bag. Gas cleaning includes pulse jet cleaning, reverse blowing air cleaning and reverse suction air cleaning.
Mechanical vibrating ash cleaning, top vibrating ash cleaning and middle vibrating ash cleaning (both for filter bags), the dust bag is installed with the help of mechanical vibrating, and periodically vibrates each dust collector bag in turn to remove the dust. Dust accumulation on the filter bags.
Manual tapping is to manually beat each filter bag to remove dust accumulation on the filter bags.
