Single-core water purification system with cavity in water pump and water purification method thereof

Abstract

The invention discloses a single-core water purification system with a cavity in a water pump and a water purification method thereof. The water purification system comprises a membrane system, and the membrane system is connected with a water inlet pipeline, a water production pipeline and a concentrated water pipeline; a water inlet electromagnetic valve, a pretreatment filter element and a water pump are arranged on the water inlet pipeline; a water production electromagnetic valve is arranged on the water production pipeline; a combination valve is arranged on the concentrated water pipeline; a water pushing pipeline is further connected to the water inlet pipeline, the water inlet end of the water pushing pipeline is connected to the water inlet pipeline at the front end of the water inlet electromagnetic valve, and the water outlet end of the water pushing pipeline is connected to the water inlet pipeline between the water inlet electromagnetic valve and the pretreatment filter element; a water pushing electromagnetic valve and a water storage cavity are arranged on the water pushing pipeline; the water production pipeline is further connected with a backflow bypass, and the water outlet end of the backflow bypass is connected to the water pushing pipeline between the water pushing electromagnetic valve and the water storage cavity; and a one-way valve and a backflow electromagnetic valve are arranged on the backflow bypass. The pretreatment filter element, the water pump and the membrane system can be flushed, and the quality of produced water of reproduced water after shutdown is ensured.

Description

technical field [0001] The invention relates to the technical field of water supply, in particular to a water purification system with a single core and a cavity in the middle of a water pump and a water purification method thereof. Background technique [0002] With the development of society and economy, people have continuously improved pursuit of quality of life and increased attention to health awareness. The safety of drinking water has been paid more and more attention. Water purification systems can produce clean, safe and reliable drinking water, and have been popularized in households and many public places. Water purification systems use various forms of membranes (such as ultrafiltration membranes, reverse osmosis membranes, etc.) to filter raw water (such as tap water) to remove impurities and obtain purified water. However, the current water purifiers have a serious shut-down salt penetration phenomenon, resulting in a considerable amount of water that has ex...

AI Technical Summary

Problems solved by technology

However, the current water purifier has a serious phenomenon of salt infiltration when it is shut down, resulting in a considerable amount of water that has exceeded the TDS after a period of shutdown.
