Abstract

The invention relates to a novel integrated flow channel membrane shell, and belongs to the field of membrane separation equipment. The integrated flow channel membrane shell comprises a pressure container, end covers at two ends of the pressure container and a connection device for connecting the pressure container and the end covers, wherein integrated flow channels are formed in the end covers. Compared with the prior art, the invention has the advantages that: the integrated flow channel membrane shell has a novel structure and is reasonable in design, a plurality of member elements are integrated into the membrane shell, and various water flow pipelines arranged outside the membrane shell are integrated into the membrane shell, so that the integral treatment effect of the equipment is improved fully, the floor space is reduced effectively, a large amount of water head loss is reduced, engineering amount is reduced, and the integrated flow channel membrane shell is easy to maintain; and the problem that the application of the membrane shell is limited for a long time is solved, and the membrane shell is convenient to install and low in economic cost, and is suitable to be popularized and applied to systems related to reverse osmosis and nanofiltration in fields of chemical industry, electric power, medicine, electronics, food, metallurgy and the like.

Description

technical field [0001] The invention relates to a novel integrated channel membrane shell, which belongs to the field of membrane separation equipment. Background technique [0002] At present, in order to improve the water production effect, the reverse osmosis and nanofiltration systems basically adopt the linear series connection of multiple membrane elements in a pressure vessel, and then use the basically uniform end cap to seal. The number of membrane elements is not more than 8, the number is very limited, and the multi-core linear series, the length of the membrane shell is significantly increased, and the occupied space is correspondingly increased, which limits the scope of application of reverse osmosis and nanofiltration systems. At the same time, for the process setting to achieve the purpose of large water treatment by connecting multiple membrane elements in parallel, the membrane shells equipped with single or multiple membrane elements in series are usually ...
