Abstract

The invention discloses a spiral-wound type reverse osmosis membrane element and a water purifier. The spiral-wound type reverse osmosis membrane element comprises a central tube bank, a plurality ofreverse osmosis membrane groups and two end covers, wherein the central tube bank comprises a pure water tube and a plurality of wastewater tubes arranged at intervals around the pure water tube; eachreverse osmosis membrane group penetrates through between the pure water tube and one wastewater tube from one end of the reverse osmosis membrane group and then is folded, and the folded reverse osmosis membrane groups are wound together along the circumferential direction of the pure water tube to the outer sides of the wastewater tubes; the two end covers are separately arranged at one ends ofthe central tube bank and the length direction of the reverse osmosis membrane groups for sealing the end parts of the reverse osmosis membrane groups, at least one of the two end covers communicateswith the central tube bank, and at least one of the two end covers communicates with the wastewater tubes; and one sides, far from the central tube bank, of every adjacent two reverse osmosis membrane groups are bonded by waterproof adhesive tapes. The arrangement of the waterproof adhesive tapes is reduced, a gluing process of the spiral-wound type reverse osmosis membrane element is simplified,and further the production efficiency of the spiral-wound type reverse osmosis membrane element is improved.

Description

technical field [0001] The invention relates to the technical field of reverse osmosis water purification, in particular to a spiral-wound reverse osmosis membrane element and a water purifier. Background technique [0002] Spiral-wound reverse osmosis membrane elements, also known as spiral-wound reverse osmosis membrane elements, are commonly used elements in water treatment technology. A sheet group, the central tube group includes a pure water pipe and a plurality of waste water pipes arranged at intervals around the pure water pipe; one end of each reverse osmosis membrane group is connected between the pure water pipe and a waste water pipe of the central pipe group After passing through, it is folded in half to form a water inlet channel connected to the waste water pipe, and a water production channel connected to the central pipe is formed between the opposite sides of two adjacent reverse osmosis membrane groups. [0003] In the existing spiral-wound reverse osmos...
