Reverse osmosis membrane element of water purifier

Abstract

The invention relates to a reverse osmosis membrane element of a water purifier. The reverse osmosis membrane element of the water purifier comprises a shell, a sealing cover, a central pipe and a membrane sheet, wherein a puncture tube is connected beside the central tube, one end of the puncture tube communicates with the central tube, the other end of the puncture tube is closed, and flow guideholes are formed in the tube walls of the central tube and the puncture tube; the outer tube walls of the central tube and the puncture tube are wrapped with a reverse osmosis membrane; the membranesheet is attached to the outer part of the central pipe in a wrapping manner, the membrane sheet comprises a flow guide supporting layer, and a reverse osmosis membrane is wrapped on the outer part ofthe flow guide supporting layer; a puncture hole matched with the puncture tube is formed in the membrane sheet, and the puncture tube wrapped by the reverse osmosis membrane penetrates through the puncture hole and then penetrates through and fixes the membrane sheet. The membrane element is ingenious in design, membrane layer materials can be fully utilized, and comprehensive utilization of resources is effectively guaranteed; the water outlet speed of the membrane element is increased, the water pressure required by water purification is reduced, and the water purification capacity and theuse experience of the membrane element are effectively improved.

Description

technical field [0001] The invention relates to the field of water purifiers, in particular to a reverse osmosis membrane element. Background technique [0002] With the development of industry, the water resources used by people have been seriously polluted, and the quality of drinking water has dropped sharply; in order to ensure the health of water, many residents have installed water purifiers for their homes; filter membranes are one of the core components of water purifiers. Among the filtration membranes currently on the market, the reverse osmosis membrane is one of the membrane elements that can filter smaller particles. Its filtration size can even reach 0.0001 microns, which can effectively filter out bacteria, microorganisms and other harmful substances in the water to ensure the purity of water quality. However, most of the current reverse osmosis membrane elements are spiral-wound. In the process of water purification, the purified water needs to flow along the...

[0002] With the development of industry, the water resources used by people have been seriously polluted, and the quality of drinking water has dropped sharply; in order to ensure the health of water, many residents have installed water purifiers for their homes; filter membranes are one of the core components of water purifiers. Among the filtration membranes currently on the market, the reverse osmosis membrane is one of the membrane elements that can filter smaller particles. Its filtration size can even reach 0.0001 microns, which can effectively filter out bacteria, microorganisms and other harmful substances in the water to ensure the purity of water quality. However, most of the current reverse osmosis membrane elements are spiral-wound. In the process of water purification, the purified water needs to flow along the porous support material for a long journey before it can be collected in the central pipe. The water outlet speed is relatively slow, and the water pressure required Large, so that the booster pump needs to work with high power and generate a lot of noise; the other hollow fiber membrane element is difficult to produce and the price is too high; in addition, the reverse osmosis membrane element is almost a one-time product. , if the membrane element is reprocessed, the integrity of the internal membrane layer may be destroyed, causing partial damage to the membrane layer, and the entire membrane layer will be completely scrapped if there is local damage, and cannot be recycled; resulting in a large waste of resources
