TLDR
In this article, a multi-section reverse-osmosis seawater desalination and saline water potential difference energy power generation coupling system was presented. But the authors did not reveal the performance of the system.Abstract:
The invention discloses a multi-section reverse-osmosis seawater desalination and saline water potential difference energy power generation coupling system which comprises a multi-section reverse osmosis device, a raw seawater pipeline, a positive osmosis device, an energy recoverer, a water turbine, a power generator and a water discharge pipeline; the raw seawater pipeline is divided into two paths: raw seawater in one path enters into the multi-section reverse osmosis device so as to be desalted and separated; raw seawater in the other path enters into the positive osmosis device, and part of fresh water in the raw seawater is mixed with high-concentration discharge water through a semipermeable membrane by virtue of osmosis pressure between the raw seawater and the high-concentration discharge water from the multi-section reverse osmosis device to push the water turbine to apply work, so as to drive the power generator to generate electricity, and the residual seawater is introduced into the multi-section reverse osmosis device after being pressurized through the energy recoverer. The system disclosed by the invention is capable of realizing favorable coupling of the multi-section reverse osmosis device and saline water potential difference energy power generation, has the characteristics of low investment cost, stability in operation and high practicability, is beneficial to practice of saline water potential difference energy power generation, further exerts the advantages of high water yield and high recovery rate of the multi-section reverse osmosis device, and reduces the influence of wastewater discharge on environment.read more
