Reverse osmosis water purifier RO film protecting system and method

Abstract

The invention relates to a reverse osmosis water purifier RO film protecting system and method. The system comprises an RO film surface flushing system and an electromagnetic resonance generator which are electrically connected. The RO film surface flushing system comprises a film surface flushing and diluting module, an RO film output water power supply module and an automatic control module which are electrically connected. The film surface flushing and diluting module comprises a pressure tank, an RO film shell inlet end pipeline, a first water feeding electromagnetic valve, a flow limiting valve, an RO film filter and a flushing electromagnetic valve which are in pipeline connection. The RO film output water power supply module comprises a pressure tank, a control valve and a check valve which are in pipeline connection. The film surface scaling probability is lowered, and the service life of the film is greatly prolonged; by arranging the electromagnetic resonance generator, resonance occurs between water inherent frequency and electromagnetic field frequency, and the separating-out speed of calcium salt in water is increased, so that electrical conductivity of concentrated water is lowered, and the machine works in a relatively safe water quality state.

Description

technical field [0001] The invention relates to the technical field of reverse osmosis water purifiers, and more specifically, relates to a reverse osmosis water purifier RO membrane protection system and a method thereof. Background technique [0002] In the reverse osmosis water purification system, almost all traditional RO machines (including most water-saving models) retain water in the RO membrane cavity after being filled with raw water (tap water). , The water retained in the RO membrane cavity is concentrated water after repeated recycling. The working mechanism of this RO machine has the following hidden dangers: the raw water or concentrated water stays in the membrane shell, and the salt in the water gradually crystallizes and precipitates due to long-term standing, especially in the north where the water quality is relatively hard, and the precipitated salt deposits On the surface of the membrane, it accumulates in the microscopic pores or folds of the membrane...

Problems solved by technology

The working mechanism of this RO machine has the following hidden dangers: the raw water or concentrated water stays in the membrane shell, and the salt in the water gradually crystallizes and precipitates due to long-term standing, especially in the north where the water quality is relatively hard, and the precipitated salt deposits On the surface of the membrane, accumulated in the microscopic pores or folds of the membrane surface, the microstructure of the membrane surface is destroyed, the desalination rate of the RO membrane is therefore rapidly reduced, and the service life is greatly shortened

In addition, the return and reuse of concentrated water is mainly used to save water, but the conductivity of the water increases rapidly, and the quality of the water produced by the RO membrane cannot be guaranteed, especially in the case of poor raw water quality.

[0003] As the core component of the reverse osmosis water purifier, the RO membrane is relatively expensive, especially the use of foreign advanced membranes, the cost is even higher
