Background
The tangential flow refers to a filtering form that the liquid flowing direction and the filtering direction are vertical, the traditional liquid dead-end filtering, also called vertical filtering, is most of microporous filtering, including the filtering form adopted by aseptic filtering, the flowing direction of the liquid is consistent with the filtering direction, along with the filtering, the thickness of a filter cake layer or a gel layer formed on the surface of the filtering membrane is gradually increased, the flow rate is gradually reduced, when the solid content in the feed liquid is very high when the filtering medium is an ultrafiltration membrane or a microfiltration membrane with fine pore diameter, the dead-end filtering mode is adopted, the flow rate is rapidly reduced, and therefore the dead-end filtering can only process the feed liquid with small volume. When large-scale feed liquid is filtered, a tangential flow filtering mode is needed, the liquid flows to generate shearing force on the surface of a filtering medium, the accumulation of a filter cake layer or a gel layer is reduced, and the stable filtering speed is ensured. Tangential flow filtration is therefore widely used in ultrafiltration and partial microfiltration processes.
When processing filtering membrane, because the department of buckling that filtering membrane set up is more, directly wash it and appear clearing up the dead angle easily, lead to clean effect not good, consequently in prior art, dismantle filtering membrane from the device is inside usually, then wash filtering membrane, but this kind of method to filtering membrane cleanness is not only loaded down with trivial details step, still consumes a large amount of time, leads to work efficiency to reduce, therefore we improve this, provide a tangential flow automatically cleaning waste water filtration processing apparatus.
