Problems solved by technology
[0002] In the reverse osmosis membrane device in the prior art, the raw water is mainly fed from one end, the concentrated water is discharged from one end, and the pure water is discharged from the center pipe. This traditional layout structure has a shorter process flow, a lower flow rate of the membrane, and water The recovery rate is low and the concentration polarization is large, which will easily lead to pollution of the membrane core, which will shorten the service life of the membrane element

The invention discloses a reverse osmosis membrane apparatus. The apparatus comprises a shell and a reverse osmosis membrane disposed in the shell, wherein the shell is provided with raw water inlets,concentrated water outlets and a pure water outlet, the inside of the shell is further provided with a central pipe, a plurality of flow guiding pipes are arranged on the circumferential side of thecentral pipe, the flow guiding pipes are provided with water distribution holes used for the raw water to enter the inside of the reverse osmosis membrane, the reverse osmosis membrane is rolled in aclockwise or counterclockwise direction along the central axis of the central pipe, the shell is further provided with an end cover, and the raw water inlets, the concentrated water outlets and the pure water outlet are all arranged on the end cover. Through the design of the above structure, the working distance of the reverse osmosis action is increased, the action flow velocity of the raw wateris enhanced, the recovery rate is improved, the concentration polarization is reduced, and thus the service life of the apparatus is improved.
Description
technical field [0001] The invention relates to a reverse osmosis membrane device. Background technique [0002] In the reverse osmosis membrane device in the prior art, the raw water is mainly fed from one end, the concentrated water is discharged from one end, and the pure water is discharged from the center pipe. This traditional layout structure has a shorter process flow, a lower flow rate of the membrane, and water Low recovery rate and high concentration polarization can easily lead to membrane core pollution, resulting in shortened service life of membrane elements. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a reverse osmosis membrane device, which specifically realizes filtration through multi-port uniform water inflow. [0004] The present invention is realized through the following technical solutions: [0005] A reverse osmosis membrane device, comprising a cas...
