A reverse osmosis membrane element with wide channel and anti-pollution

Abstract

The invention discloses a wide channel pollution-resistant reverse osmosis membrane element, which comprises a membrane element body and end caps placed at both ends of the membrane element body. The reverse osmosis membrane on the central tube is composed of the membrane element body, which also includes a water inlet spacer and a fresh water collection net. Between the sheets, the reverse osmosis membrane after being folded in half is sealed and fixed by resin sealant and fresh water collection net; in the present invention, the reinforcement plate and the end cover body are connected through the chute, which is convenient for installation and removal of the reinforcement plate, and is convenient for its maintenance. For replacement and maintenance, the reinforced plate has a curved structure, and it has good impact resistance during the process of water impacting it, which can increase its service life.

Description

Technical field [0001] The present invention relates to the technical field of reverse osmosis membrane components, and more particularly to a reverse osmosis membrane element that is contaminated with a wide flow. Background technique [0002] The reverse osmosis membrane is widely used in electricity, petrochemical, steel, electronics, medicine, food, drinks, municipal and environmental protection, etc., in seawater and bitter salty water, boiler water, industrial pure water and electronic super pure water, drink purity Water production, wastewater treatment and special separation process play an important role. The existing reverse osmosis membrane can be divided into the following types, tubular, plate frame, hollow fiber and roll. The roll-free reverse osmosis membrane is a plastic tube that is laminated with a grid plastic network with a film, and a woven fabric is laid around a plastic tube in a hedge. The diaphragm is sealed into a sealed bag, and the water is collected i...

Problems solved by technology

[0003] However, because the existing roll-type reverse osmosis membrane is directly wound on the plastic pipe with a grid-shaped plastic net and a diaphragm, the pure water is transmitted and collected slowly during use, and the utilization rate of the diaphragm is low, resulting in unnecessary At the same time, the water distribution of the reverse osmosis membrane is uneven, the flushing force of the membrane surface is low, the amount of pollutants is easy to accumulate, the cleaning cycle is short, and the membrane element is difficult to clean after contamination, and the system efficiency is low; and it is not easy to install and disassemble. board to improve its impact resistance; at the same time, cutting equipment is needed to cut the reverse osmosis membrane when making reverse osmosis membrane elements, but the existing cutting equipment is not easy to adjust, and can only cut single-shaped reverse osmosis membranes, which is practical poor sex
