Problems solved by technology
However, the conventional reverse osmosis membrane element production method is to fix the reverse osmosis membrane element with an epoxy shell to form an integral reverse osmosis membrane element. When the reverse osmosis membrane element is seriously polluted or the concentrated water channel is polluted and blocked, it is difficult to clean it by chemical cleaning. clean, resulting in a decrease in the permeation flux and water flow of the reverse osmosis membrane, and even causing the membrane element to be unusable, hindering its deep application in actual use

Embodiment approach 1
[0014] Embodiment 1: Open a raw water inlet on the side wall of the membrane shell 2, connect the raw water pipe to the raw water inlet, after the raw water enters the reverse osmosis membrane element, after the separation of the membrane working part 3, the purified water permeates through the membrane working part 3 Enter the center pipe 4, and the remaining concentrated water flows out through the pressure-resistant seals 1 at both ends.
[0015] Embodiment 2: One end of the central pipe 4 is sealed, and the raw water pipe is connected to one end of the membrane shell 2. Since the pressure-resistant seal 1 communicates with the inside of the membrane shell 2, the raw water flows in from one end of the pressure-resistant seal 1, and the purified water enters Central pipe 4, the concentrated water flows out from the pressure-resistant seal 1 at the other end of the membrane housing 2.
[0016] As the center pipe 4 where the clean water gathers, its two ends need to be extende...

The invention discloses a reverse osmosis membrane element, comprising a membrane casing and a membrane work piece, wherein the membrane work piece comprises a reverse osmosis membrane and a central tube, the reverse osmosis membrane is reeled over the central tube, the membrane work piece is inserted into the membrane casing, and two ends of the membrane casing are provided with anti-compression sealing members used for fixing the membrane work piece and capable of being dismounted. With such a technical scheme, the invention has the following advantages: if the membrane work piece is severely contaminated and a thick water channel is severely blocked, the membrane work piece can be taken out from the membrane casing and then be unfolded and cleaned; the reverse osmosis membrane element has a simple structure, is convenient to dismount and overcomes the defect that a contaminated membrane work piece cannot be taken out for cleaning in the prior art because of integrated molding of the membrane work piece and a membrane casing.
Description
technical field [0001] The invention relates to the field of membrane filtration equipment, in particular to a reverse osmosis membrane element that can be disassembled and cleaned for internal membrane working parts. Background technique [0002] The principle of reverse osmosis and reverse osmosis equipment have been widely used in utilizing water resources and strengthening environmental protection, especially in material concentration and material separation. However, the conventional reverse osmosis membrane element production method is to fix the reverse osmosis membrane element with an epoxy shell to form an integral reverse osmosis membrane element. When the reverse osmosis membrane element is seriously polluted or the concentrated water channel is polluted and blocked, it is difficult to clean it by chemical cleaning. Clean, resulting in the reverse osmosis membrane permeation flux, water flow decline, and even make the membrane element can not continue to use, hind...
