Description

Technical Field

[0001] The utility model relates to the technical field of hollow fiber membrane component equipment, in particular to a cleaning device for a hollow fiber membrane component. Background Art

[0002] The hollow fiber membrane assembly uses the hollow fibers inside it to achieve the filtering function. By connecting the liquid inlet valve at one end of the hollow fiber membrane assembly and the liquid outlet valve at the other end, the muddy water circulation is realized. A water storage area is set at one end of the hollow fiber, and a pipeline is connected to the water storage area on one side. The water in the water storage area is sucked out by pressure, and the hollow fiber membrane can be used for filtering. When cleaning the hollow fiber membrane assembly, the common method is backwashing, that is, pressurizing the water storage area to diffuse the purified water from the inside of the hollow fiber membrane to the outside, so that the impurities on the surface of the hollow fiber membrane fall off, and then through this process, the impurities on the surface of the hollow fiber membrane can be removed. In this process, the removal effect of impurities is poor, and it takes a long time to separate most of the impurities on the surface of the hollow fiber membrane from the hollow fiber membrane.
