Water purifying system

Abstract

The invention discloses a water purifying system, comprising a membrane filter element, a wastewater reflow valve and a controller. The membrane filter element includes a shell and a membrane component. The shell is provided with a raw water port, a purified water port and a wastewater port; the membrane component includes a center tube communicated with the purified water port, a plurality of waste discharge tubes communicated with the wastewater port, and a plurality of reverse osmosis membrane units; the waste discharge tubes are arranged at intervals along the periphery of the center tube;one end of each reverse osmosis membrane unit is passed through one waste discharge tube and the center tube and is then folded, an inflow passage communicated with the waste discharge tube is formed; a water producing passage communicated with the center tube is formed between every two adjacent reverse osmosis membrane units and is communicated with a water inlet; the inflow end of the wastewater reflow valve is connected to a wastewater tube, and the outflow end of the wastewater reflow valve is connected to a raw water tube; the controller is electrically connected with the wastewater reflow valve. Therefore, flow speed in the membrane units is ensured, the membrane units are never blocked, it is ensured that the water purifying system can filter wastewater that flows back, and waterproducing rate is increased.

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 healthy drinking water has been strengthened, and it is also the root of the hot water purification equipment market. [0003] The core component of the existing water purification system is the membrane filter element, and the pipelines connected to it include raw water pipelines, pure water pipelines, waste water pipelines and return pipelines. The return pipeline connects the waste water pipelines with the raw water pipelines to Part of the wastewater generated after filtration by the membrane filter element can flow back into the membrane filter element for filtration, thus improving the wa...

Problems solved by technology

[0004] However, the water flow rate in the internal water channel of the existing membrane filter element is relatively slow, which is easy to deposit dirt and impurities, which in turn leads to the blockage of the internal water channel of the membrane filter element, resulting in low water production rate of the entire water purification system, resulting in waste of water
