A side stream reverse osmosis filter

Abstract

The invention discloses a lateral flow type reverse osmosis filter to solve a series of problems of incomplete utilization of membrane elements, imbalance of utilized areas of the membrane elements, low raw water introduction efficiency, slow filtering speed and unsatisfactory filtering effect in the prior art. The lateral flow type reverse osmosis filter for solving the problem is mainly characterized in that a purified water channel and a concentrated water channel are arranged at the center of the filter, the purified water channel is communicated with a purified water outlet, the concentrated water channel is communicated with a concentrated water outlet, membrane elements wind around the purified water channel and the concentrated water channel to form a reverse osmosis filter element, a produced water flow channel spirally extending to the center is formed between two adjacent membrane elements, the membrane elements positioned on the sidewall of the reverse osmosis filter element form a raw water inlet communicated with the produced water flow channel, a raw water accommodating chamber is formed between the outer side of the reverse osmosis filter element and the inner sideof a shell, and the raw water inlet is communicated with the raw water inlet through the raw water accommodating chamber. The lateral flow type reverse osmosis filter is mainly used for reverse osmosis purification of water.

Description

technical field [0001] The invention relates to a side flow reverse osmosis filter, which belongs to the technical field of water treatment. Background technique [0002] Water is an important part of the human body. The water in the human body accounts for about 50% of an adult's body weight. The average daily water consumption of a normal person is 2000-2500 ml, and the oxidation of substances in the body can produce 300 ml of water, so it should be replenished every day About 2000 ml of water, most of which are obtained through drinking water. However, with the continuous aggravation of water pollution, it is becoming more and more difficult to drink healthy water, and other organs of the human body will also be damaged due to long-term pollution. The tap water for daily drinking has gone through a variety of cleaning, sterilization and disinfection methods, and the water quality test at the factory can meet the national hygiene standards, and then flows into thousands o...

AI Technical Summary

Problems solved by technology

The side-flow reverse osmosis filters in the prior art all adopt the structure of double channels in the center, which are used to introduce raw water and collect clean water respectively, while the outside of the reverse osmosis filter element is used to export concentrated water, but this Waterway design will also bring problems such as low efficiency of raw water introduction, large internal water resistance and obvious pressure drop
