Abstract

The invention discloses a membrane element which comprises a filtering membrane and a membrane protective device, the filter membrane is provided with a raw water flow channel and a pure water flow channel which are mutually separated, the outlet of the raw water flow channel is located at at least one side edge of the filter membrane, the membrane protective device sleeves outside the filter membrane, the membrane protective device is provided with at least one opening communicated with the outlet of the raw water flow channel, and a fluid flowed from the outlet of the raw water flow channel is led out of the membrane protective device by the membrane protective device via the opening. The membrane element can reduce the deposition of pollutants at the outlet of the raw water flow channel of the filter membrane, and the service life of the membrane element can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a membrane element. Background technique [0002] The common application form of filtration membrane technology in water treatment is generally made of spiral-wound membrane elements, also known as spiral-wound membrane elements. The opening side of the coiled membrane element is bonded to the central tube with openings, and the membrane element is wound on the central tube at the same time, so that the feedwater flow flows through the outside of the filter membrane, and under the feedwater pressure, the fresh water enters through the membrane element. inside the central tube. [0003] The invention patent with the Chinese patent publication number CN102976447A discloses a membrane element, figure 1 It is a schematic diagram of the appearance of a membrane element in the prior art of the above-mentioned patent. Such as figure 1 As shown, there is a central tube in the...
