Description

Technical Field

[0001] The utility model relates to the field of filtering equipment, in particular to a high-efficiency bag filter. Background Art

[0002] Bag filter is a multi-purpose filtering equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, closed working and strong applicability; its working principle is to use filter bag to filter the fluid, filter out impurities, particles and other substances in it, so as to achieve the purpose of purifying the fluid. Bag filter is usually composed of filter housing, filter bag, inlet and outlet pipes, support basket, etc. The filter bag is made of polyester, polypropylene, nylon, polytetrafluoroethylene and other materials. Filter bags made of different materials have different filtering accuracy and corrosion resistance.

[0003] When in use, the liquid to be filtered is passed into the filter, filtered through the filter bag and then discharged, and debris remains in the filter bag. When used for a long time, the debris will be evenly distributed on the inner wall of the filter bag, gradually blocking all the mesh holes of the filter bag, causing the filtration efficiency to gradually decrease. Therefore, it is very important to improve the filtration efficiency of the bag, so a device is urgently needed to solve the above problem. Utility Model Content
