Description

Technical Field

[0001] The utility model relates to the technical field of seawater desalination water treatment, in particular to a high-pressure water energy recovery forward transfer device. Background Art

[0002] Desalination, which is the use of seawater to desalinate and produce fresh water, is an open-source incremental technology for realizing the utilization of water resources. It can increase the total amount of fresh water and is not affected by time, space and climate. It can ensure a stable water supply for drinking water for coastal residents and water replenishment for industrial boilers. In the seawater desalination membrane water treatment process, energy recovery devices are often used to recover the high-pressure energy in high-pressure concentrated water and transfer energy to boost the low-pressure incoming water. The more commonly used methods are the double-pressure cylinder method and the rotor method. Among them, the double-pressure cylinder method has greater water hammer and wear during conversion, and the rotor method has problems such as large vibration, small water production and high water mixing rate, which reduces its practicality. Therefore, we have introduced a high-pressure water energy recovery forward transfer device. Utility Model Content
