Film-covered dust bag skeleton filter bag is a cylindrical body surrounded by a single layer of fabric, usually round, characterized by a simple structure, easy to remove dust, when the dust air through the filter bag, with the help of screening, collision, interception The action separates the dust from the air stream.
1. Filter bag filter: The filter bag is a cylindrical body surrounded by a single layer of fabric, usually round, characterized by the structure of a simple dust collector frame to facilitate cleaning. When the dust-laden air passes through the filter bag, the dust is separated from the air flow by means of screening, collision, interception, and the like. The advantages of filter bag filtration are high filtration efficiency, dust removal efficiency of more than 99.5% screw conveyor in the dust chamber of the textile mill, simple structure, low power consumption. Disadvantages are the prone to fire, the filter bag is easy to congeal, the amount of filtered air per unit area is small, and the amount of filter cloth is large. In the short period of time after cleaning, the dust concentration of the filtered air with high dust concentration is poor, and the labor conditions are poor.
2. Filled Filter Bed Filtration: Filled filter bed is to cover porous filter materials such as foam plastics, non-woven fabrics and plushs on mesh drums, flat plates and other components. By virtue of its good surface filtration and internal filtration, the dust is separated from the air stream. The advantages of the filtered filter bed are the large amount of filtered air, low resistance, and dust filtration. Bag filter standard
3, dust bag cage filter: Dust bag cage is a cylinder surrounded by a metal mesh, open ends of the cylinder and the air channel. The dust cage uses the airflow pressure generated by the fan to press the dust-laden air against the surface of the dust cage. Most of the short fluff and impurities are trapped on the surface of the dust cage. A filter net layer is formed, and the dust-laden air that passes through the dust cage enters the second-stage filtration device through the channels on both sides of the dust cage. Pre-separator can be regarded as a type of filter. The advantage of dust cage filtration is that there are fewer auxiliary equipments and the treatment is simple and convenient. The filtered cotton quilts have a high reuse rate and are generally assembled into dust filtration equipment with other filtration methods. The disadvantage is that the air volume is not large, the area is relatively large, and the power consumption is high.
