Problems solved by technology

[0004] At the same time, the current reverse osmosis membrane elements need to clean up the impurities on the reverse osmosis membrane more frequently, and sometimes even need to replace the reverse osmosis elements on the water purifier more frequently, which reduces the use efficiency and increases the use cost

Embodiment 1

[0033] A reverse osmosis membrane element, comprising a central pipe 1 and a reverse osmosis membrane group wound on the central pipe 1, and a plurality of water inlet holes 6 communicating with the reverse osmosis membrane group are uniformly arranged on the body of the central pipe 1 , the inner end of the reverse osmosis membrane group is fixedly connected with the central pipe 1 .

[0034] The reverse osmosis membrane set includes reverse osmosis membranes with 7 opposite folds on the front (i.e. 7 folds on the front to the inside and 8 folds on the back to the outside). The water channel, the raw water or concentrated water in the water inlet channel can only permeate from the front 7 to the reverse 8 of the reverse osmosis membrane, but cannot penetrate from the reverse 8 to the front 7 of the reverse osmosis membrane so as to avoid the obtained pure water from penetrating into the reverse osmosis membrane again. Raw water or concentrated water, that is, the side of the ...

Embodiment 2

[0047] The difference between the second embodiment and the first embodiment is that in the second embodiment, the end caps 51 and 52 are used to replace the second waterproof tapes 21 and 23 in the first embodiment to realize the sealing of both ends of the reverse osmosis membrane element.

[0048] In this embodiment, the reverse osmosis membrane is also provided with a second waterproof adhesive tape 11 around the reverse side, because when the end caps 51 and 52 are used, the raw water or concentrated water will flow out from both sides of the water inlet channel and pass through the second The waterproof adhesive tape 11 can effectively prevent raw water or concentrated water flowing out from the water inlet channel from entering into the produced water channel to pollute the pure water.

[0049] The usage method of the reverse osmosis membrane element of this embodiment is exactly the same as that of the first embodiment.

Abstract

The invention discloses a reverse osmosis membrane element and water purification equipment. The reverse osmosis membrane element comprises a central pipe of which the pipe body is provided with water inlet holes and a reverse osmosis membrane group which winds the central pipe; the reverse osmosis membrane group comprises a reverse osmosis membrane of which the front surface is folded; the front surface interlayer of the reverse osmosis membrane forms a water inlet flow channel; the back surface interlayer of the reverse osmosis membrane forms a water production flow channel which is communicated with the central pipe; the reverse osmosis membrane element also comprises a partition structure for dividing the water inlet flow channel into a raw water side water inlet flow channel and a concentrated water side water inlet flow channel which are communicated with each other in the axial direction of the central pipe along a water flowing direction; raw water flows into the raw water side water inlet flow channel from the side surface of the reverse osmosis membrane element; concentrated water flows out from the concentrated water side water inlet flow channel from the side surface of the reverse osmosis membrane element. According to the reverse osmosis membrane element, the retention time of the raw water in the reverse osmosis membrane is prolonged; the conversion rate of converting the raw water into pure water can be improved.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a reverse osmosis membrane element and water purification equipment. Background technique [0002] The reverse osmosis membrane element is the core component of the water purifier. The reverse osmosis membrane element currently used is mostly a roll-type reverse osmosis membrane element. The roll-type reverse osmosis membrane element includes a central tube and is wound on the central tube and connected to the central tube. reverse osmosis membrane. [0003] In order to continuously improve the water purification effect of the roll-type reverse osmosis membrane element, people have made many improvements to it, but the water inlet and outlet methods of the reverse osmosis membrane element in these improvements can be summarized as follows: raw water enters from the central tube, fresh water Flow out from the end face or side of the membrane element, concentrated water flows out fr...
