Abstract

The invention discloses a tubular membrane filtering device capable of automatically scrubbing the membrane surface. The tubular membrane filtering device comprises a tank body, a tubular membrane filtering component, a solution inlet, a concentrated solution outlet, a permeated solution outlet and an automatic membrane surface scrubbing system, wherein the tubular membrane filtering component which is not contacted with the inner wall of the tank body is arranged inside the tank body; the solution inlet and the concentrated solution outlet are communicated with gap spaces of the tank body and the tubular membrane filtering component; and the permeated solution outlet is communicated with the interior of the tubular membrane filtering component. The tubular membrane filtering device capable of automatically scrubbing the membrane surface can obviously restrain membrane pollution, remarkably delay attenuation of membrane flux and make an effect of separating materials from solution better and efficiency higher, is easy to operate, has low production cost and running cost, and can be widely applied to a plurality of fields of biological engineering, medicaments, foods, beverages, waste water treatment and the like.

Description

technical field [0001] The invention relates to a membrane filtration device, in particular to a tubular membrane filtration device suitable for automatically scrubbing the surface of the membrane for filtering liquid. Background technique [0002] In recent years, the application of membrane separation technology in the fields of bioengineering, medicine, food, beverage and wastewater treatment has developed rapidly. However, how to reduce the influence of membrane fouling and concentration polarization and delay the attenuation of membrane flux is still a problem. One of the main problems in the development of membrane separation technology. [0003] Although the development of high-performance membrane materials has reached a very high level, under the premise of the performance of existing membrane materials, starting from the membrane separation operation process and equipment to strengthen the mass transfer process of membrane separation, control membrane fouling and c...
