Description

Water inlet type tubular membrane water inlet and distribution plate

Technical Field

The utility model relates to the technical field of water purifying devices, in particular to an upper water inlet type tubular membrane water inlet and distribution plate.

Background

In the hollow fiber filtration membrane adopting an upper water inlet mode, when raw water enters a pipeline, membrane filaments in the pipeline are dense, raw water flow is easily blocked by the surrounding membrane filaments, so that a region which is difficult to pass by partial water flow is easily formed, and the flux of the whole membrane module is influenced. At the same time, the washing of the water flow can cause the membrane filaments to shake, and the shaking is most likely to cause the membrane filaments to break at the joint with the glue.

The prior structure mostly has the following problems: the flux of the whole membrane module is influenced by the dead water end, and meanwhile, the scouring effect of the cross flow on the surface of the membrane filaments is greatly reduced, so that the blocking of the membrane is further accelerated, and the flux reduction of the membrane module is accelerated. In addition, the problems of incomplete cleaning, poor cleaning effect and the like are caused during chemical cleaning, backwashing and air washing. And the membrane silk breakage can directly cause the effluent quality to be poor, and the membrane component must be replaced when the breakage number is large. Therefore, a novel water inlet and distribution plate of the water inlet type tubular membrane is needed to overcome the technical defects.
