The bag filter is a professional liquid filtration device in the process of use, and the device can effectively remove the particles of different sizes in the liquid during the process of use, so that the liquid filtration and purification can be effectively achieved. Separation, recycling purposes.
The bag filter is mainly composed of supporting basket, filter bag and filter container. When the bag filter is used to filter the liquid, the liquid enters from the side or below the liquid inlet of the filter container, and the filter is supported by the basket. Above the bag is punched into the filter bag. The filter bag is unfolded due to the impact of the liquid and the uniform pressure surface, so that the liquid material is uniformly distributed on the inner surface of the entire filter bag. The liquid passing through the filter bag is along the wall of the metal supporting basket and is filtered by the filter. Bottom liquid outlet.
The particulate impurities filtered out in the bag filter are effectively trapped in the filter bag, thus completing the filtration process, in order to maintain the efficient flow and filtration accuracy of the filter and ensure that the downstream liquid is not contaminated during use. After a period of operation, the machine should be shut down, open the filter cover, remove the retentate and the filter bag, and replace the new filter bag. The replacement cycle depends on the actual situation.
The bag filter is divided into single bag type, double bag type and multi bag type according to the number of bags contained in the filter; it is divided into a side-in bottom-out type and a bottom-in bottom out type in the direction of liquid inlet and outlet. The filter material is a high quality stainless steel. Such as 304,316,316L and so on. FY series stainless steel bag filter has the characteristics of large processing capacity, large volume of dirt, small volume, obvious filtering effect, simple operation and low operating cost.
Bag filter bag, in the process of production is mainly selected imported high-strength filament fiber raw material acupuncture, the surface by a special singeing treatment, effectively prevent the fiber shedding contamination of the filtrate, fluffy uniform three-dimensional filter layer Solid and colloidal particles have a very high ability to capture, high-strength long fibers make the filter bag filter efficiency is stable, and the service life is longer. The filter bag is produced according to the European and American international standards, and meets the GMP requirements of the domestic pharmaceutical industry and FDA requirements. It is an important filter element in the bag filter system, and the quality of the filter bag determines the filtration efficiency.
