All-effect reverse osmosis membrane element and pure water machine

摘要

An all-effects reverse osmosis membrane element and a pure water machine, the all-effects reverse osmosis membrane element includes a central tube (10) and a reverse osmosis membrane (20), and the central tube (10) has some water collecting holes (10). 11) Provided, the reverse osmosis membrane (20) is wound with a central tube (10) to cover each water collecting hole (11), and the reverse osmosis membrane (20) forms a raw water flow path and reverses. A first waterproof barrier (21) and a second waterproof barrier (22) are sealed on both sides of the osmosis membrane (20), and the first waterproof barrier (21) and the central tube (10) are first concentrated. The water outlet (211) is formed, the first waterproof barrier (21) and the reverse osmosis membrane (20) form the second concentrated water outlet (212), and the second waterproof barrier (22) and the reverse osmosis membrane are formed. (20) forms the first raw water inlet (221), and the second waterproof barrier (22) and the central tube (10) form the second raw water inlet (222). [Selection diagram] Fig. 1
