Novel membrane filtering system

Abstract

The invention discloses a novel membrane filtering system which comprises a membrane shell, membrane elements fixed in the membrane shell and end covers for sealing two ends of the membrane shell. The novel membrane filtering system is characterized in that two ends of the membrane shell are provided with water inlets; at least two membrane elements are arranged; a central produced water collecting tube is arranged at the center of the membrane shell in a running through way; the central produced water collecting tube passes through the membrane shell and the centres of the end covers and passes through the centres of the membrane elements; a filtered water guiding device is mounted on the central produced water collecting tube; bypass distribution tubes are formed between outer walls of the membrane elements and inner walls of the membrane shell; and the opening end of the water inlet is connected with the bypass distribution tubes. The novel membrane filtering system provided by the invention has the characteristics of simple structure, low cost, uniform water distribution of the membrane elements, greatly reduced cross contamination possibility, easiness in processing and capability of greatly increasing sewage filtering efficiency.

Description

technical field [0001] The invention relates to a filter system in an anhydrous treatment plant, in particular to a novel membrane filter system. Background technique [0002] Existing membrane filtration systems are all composed of membrane shells, sequentially connected membrane elements located in the membrane shells, and end caps that seal the membrane shells. Water collection pipe, while the central water collection pipe runs through the center of each membrane element, and there are multiple bypass water distribution pipes on the outer circumference of the central water collection pipe. Each membrane element includes a fan-shaped membrane filament group composed of countless membrane filaments. The fan-shaped membrane filament group is arranged in a ring, and the edge of the membrane filament group is provided with a deflector, and the deflector is connected to the central water production collection pipe. In this way, the sewage enters the membrane shell from the wat...

Problems solved by technology

However, since the channel of the bypass water distribution pipe in the membrane element is full of sewage, and the outside of the bypass water distribution channel and the adjacent central product water collection pipe are filled with filtered clean water, the chance of cross contamination is relatively large, and Affect the effect of sewage treatment, and because the water is distributed through the bypass water distribution pipe in the membrane element, there will always be uneven water distribution
