Reverse osmosis membrane filter element and water purifier

Abstract

The invention provides a reverse osmosis membrane filter element and a water purifier. The reverse osmosis membrane filter element comprises a central shaft; water inlet pipes, wherein the sidewall ofeach water inlet pipe is provided with at least one raw water outlet, at least one end of each water inlet pipe forms a raw water inlet, and a plurality of the water inlet pipes are arranged around the central shaft to form a central pipe group; and at least one reverse osmosis membrane module, wherein reverse osmosis membranes in the reverse osmosis membrane module are configured to pass throughspace between the central shaft and the water inlet pipes, and are rolled around the central pipe group to form a main filter element body having an inflow water passage and a produced water passage,the inflow water passage is in communication with the raw water outlets, a concentrated water out is formed in one side, away from the water inlet pipes, of the inflow water passage, and a pure wateroutlet is formed in at least one of the two sides, along the axis direction of the central pipe group, of the produced water passage. The reverse osmosis membrane filter element and the water purifier of the invention have high water making efficiency and good anti-pollution performance.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a reverse osmosis membrane filter element and a water purifier. Background technique [0002] The existing reverse osmosis membrane filter element includes a central pipe and a reverse osmosis membrane module. The reverse osmosis membrane module is wound around the central pipe to form a main body of the filter element. One end of the main body of the filter element forms a raw water inlet, and the other end forms a concentrated water outlet. The central pipe and The end on the same side as the concentrated water outlet forms a pure water outlet. The filtration principle of the reverse osmosis membrane filter element is that the direction of raw water inlet and concentrated water outflow is parallel to the central pipe, and the direction of product water outflow is perpendicular to the central pipe. The separation of raw water, concentrated water and pure water is realized by se...
