Embodiment Construction

[0029] The present invention will be further stated below in conjunction with the accompanying drawings, and the present invention will be implemented in detail.

[0030] according to figure 1 As shown in the process, first start the power supply, turn on the water pump 1, and input the raw water into the energy recovery device 5. The energy recovery device 5 has two hydraulic cylinders. figure 2 Shown as 11 or 12 in , the high-pressure raw water enters the reverse osmosis device 10 through the two outlets of the energy recovery device 5 and through the check valve 3 or 8 . Subsequently, the desalinated water comes out of the device and enters the fresh water supply system; the pressurized concentrated water enters the four-way function valve 9, passes through the four-way function valve 9, and then enters one of the hydraulic cylinders 11 of the energy recovery device 5, and the waste concentrated water flows from another The outlet of one hydraulic cylinder 12 flows back i...

Abstract

The invention discloses energy-saving reverse osmosis treatment system. It uses high pressure operation condition of itself, recoveries and uses the residual pressure energy to achieve purpose. According to fluid pressure principle, connect two hydraulic equipments to form energy recovery device; uses reverse osmosis dense water pressure as drive force to complete conveying process and recovery. The advantage of this invention is that decreases energy consumption, convenient to operate and simple, and fits to all kinds situations for reverse osmosis system.

Description

technical field [0001] The invention relates to a reverse osmosis treatment system, in particular to a reverse osmosis treatment system with an energy recovery device. Background technique [0002] The 21st century will be the century of water. my country is a country with abundant water resources, but also one of the most water-scarce countries. According to the "21st Century China's Sustainable Development Water Resources Strategy Research Report" proposed by the Chinese Academy of Engineering in July 2000, it is predicted that by 2010, my country's water demand will be 730 billion cubic meters, and the water supply will be 620-630 billion cubic meters. 100 billion cubic meters. [0003] Desalination of seawater and treatment of brackish water with high salinity is an important way to solve the shortage of water resources in coastal cities and islands in my country and increase the total amount of fresh water resources. Since my country's first reverse osmosis seawater d...
