Problems solved by technology

[0003] Existing water purification equipment mainly relies on membrane filter elements to filter raw water and produce pure water. However, when the water purification equipment is in a standby state, raw water, waste water and pure water will exist in the membrane filter element of the water purification equipment at the same time, while raw water and The concentration of TDS in wastewater is much higher than that of pure water.

Abstract

The invention discloses a water purification system, comprising: a membrane filter element, having a raw water port connected with a raw water pipe, a purified water port connected with a purified water pipe, and a wastewater port connected with a wastewater pipe; a water pump mounted on the raw water pipe; an inflow valve mounted on the raw water pipe on the inflow side of the water pump; a firstvalve mounted on a purified water pipe; an ion exchange filter element mounted on the purified water pipe between the membrane filter element and the first valve; a second valve, wherein the inflow end of the second valve is communicated with the purified water pipe between the ion exchange filter element and the first valve, and the outflow end of the second valve is communicated with the raw water pipe. After the water purification system starts to produce water and when the membrane filter element meets preset flushing conditions, the inflow valve is closed, the second valve is opened, thewater pump is started to drive purified water in the membrane filter element to pass through the ion exchange filter element and reflow into the membrane filter element, and the membrane filter element is full of the purified water. Therefore, the quality of a first cup of purified water produced by the water purification system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a water purification system. Background technique [0002] The problem of drinking water is a matter of great concern to the public. It is an indisputable fact that there are many substances that are not conducive to health in the water. This is also the main reason why people's awareness of healthy drinking water has been strengthened, and it is also the root of the hot water purification equipment market. [0003] Existing water purification equipment mainly relies on membrane filter elements to filter raw water and produce pure water. However, when the water purification equipment is in a standby state, raw water, waste water and pure water will exist in the membrane filter element of the water purification equipment at the same time, while raw water and The concentration of TDS in wastewater is much higher than that of pure water. If the water purification equipmen...
