Abstract
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
The present invention relates to a kind of membrane filter system field, particularly a kind of reverse-osmosis membrane element of dismantled and assembled cleaning internal membrane work package.
Background technology
Principle of reverse osmosis and reverse osmosis equipment extensively are applied in the resource of utilizing water and strengthen environmental protection, especially material concentrate and feed separation on also adopted by people gradually.But conventional reverse-osmosis membrane element preparation method, with reverse-osmosis membrane element fixedly all-in-one-piece reverse-osmosis membrane element of epoxy shell, reverse-osmosis membrane element is when being subjected to severe contamination and dense aquaporin and being subjected to contamination and plugging, Chemical cleaning also is difficult to clean up, cause reverse osmosis membrane permeation flux, discharge to descend, even cause membrane component can't continue to use, hindered its degree of depth in actual use and used.
Summary of the invention
The problem to be solved in the present invention provides a kind of simple in structure, and reverse-osmosis membrane element is easily cleaned in dismounting.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of reverse-osmosis membrane element, comprise film shell and film work package, described film work package comprises reverse osmosis membrane and central tube, described reverse osmosis membrane is wound on the described central tube, described film work package is plugged in the described film shell, and described film shell two ends are provided with for fixing described film work package and compressive sealed of can be disassembled.
Improved, described central tube two ends extend on described compressive sealed.
Improved, described compressive sealed is communicated with described film enclosure.
Improved, described central tube is provided with several blastholes.
Improved, also comprise seal washer, described seal washer is located at described compressive sealed and film shell junction.
Beneficial effect of the present invention:
Among the present invention, reverse osmosis membrane is wound on the described central tube, the film work package is plugged in the described film shell then, described film shell two ends are provided with dismountable compressive sealed, after adopting technique scheme, the present invention has following advantage: when the film work package is subjected to severe contamination and dense aquaporin is subjected to it to be taken out the film shell when seriously stopping up, launch then to clean, simple in structure, easy accessibility has solved prior art because of film work package and the one-body molded defective that contaminated die worker's workpiece can not be taken out cleaning of film shell.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
Fig. 1 is the schematic diagram of reverse-osmosis membrane element of the present invention.
The specific embodiment
As shown in Figure 1, a kind of reverse-osmosis membrane element, comprise film shell 2 and film work package 3, described film work package 3 comprises reverse osmosis membrane and central tube 4, described reverse osmosis membrane is wound on the described central tube 4, described film work package 3 is plugged in the described film shell 2, described film shell 2 two ends are provided with for fixing described film work package 3 and compressive sealed 1 of can be disassembled, during concrete enforcement, at first with the film work package 3 launched around central tube 4, and the tubular membrane work package consistent with film shell 2 diameters advanced its plug-in mounting in the film shell 2 then, in order to prevent that film work package 3 is offset away from two ends, install compressive sealed 1 at film shell 2 two ends, simultaneously, compressive sealed 1 and described film shell 2 internal communication, concrete working method, adopt two kinds of embodiments:
Embodiment one, offer a former water inlet at film shell 2 sidewalls, raw water tubes is connected with former water inlet, after former water enters in the reverse-osmosis membrane element, centrifugation through film work package 3, water purification penetrates film work package 3 and enters central tube 4, and remaining dense water is by compressive sealed 1 outflow at two ends.
Embodiment two in the sealing of central tube 4 one ends, is connected to raw water tubes at one end of film shell 2, be connected with film shell 2 inside owing to compressive sealed 1, therefore former water is flowed into by compressive sealed 1 one ends, and water purification enters central tube 4, and dense water is from compressive sealed 1 outflow of film shell 2 other ends.
As the central tube 4 of water purification junction, its two ends need extend on described compressive sealed 1, and to prevent dense water in die worker's workpiece 3 to the pollution of water purification, simultaneously, central tube 4 is provided with several blastholes, and water purification flows in blasthole.
For make compressive sealed 1 and film shell 2 between the junction sealing effectiveness better, described compressive sealed 1 with film shell 2 junctions seal washer is set, reach better sealing effectiveness.
Below for the disassembly, cleaning of reverse-osmosis membrane element of the present invention with the process of going back is installed: when film work package 3 is subjected to severe contamination and dense aquaporin and is subjected to seriously stopping up, the seal washer at film shell 2 two ends is extracted, compressive sealed 1 of the following two ends of dismounting then, at last die worker's workpiece 3 is taken out, during cleaning, the film work package 3 that is wound on the central tube 4 is launched, cleaned then, simultaneously, compressive sealed 1 with two ends also cleans.When the both clean finish after, film work package 3 plug-in mountings of the central tube 4 of will reeling back successively advance film shell 2, two ends are installed compressive sealed 1, the last sheathed good seal washer in junction at compressive sealed 1 and film shell 2.
Except above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
