TLDR
In this paper, a pressure-reducing osmosis for power generation was proposed, in which seawater with high osmotic pressure was introduced into a membrane component, fresh water was entered one side of the seawater through an Osmosis membrane, and one part of the high pressure diluted seawater was used for recovering the water pressure, and the other part of high-pressure dilated seawater is used for generating power.Abstract:
The invention relates to a device for generating power by utilizing osmosis energy. The device adopts the principle of pressure-reducing osmosis for power generation, and is characterized in that seawater with high osmosis energy is introduced into a membrane component, fresh water enters one side of the seawater through an osmosis membrane under the action of osmotic pressure so as to obtain high-pressure diluted seawater; and one part of the high-pressure diluted seawater is used for recovering the water pressure, and the other part of the high-pressure diluted seawater is used for generating power. The device has the advantages that the influence of the performance of the membrane on the power generation is extremely large, a self-made membrane component capable of eliminating concentration polarization and a self-made forward osmosis membrane with high osmosis flux are adopted as a core of the membrane component, the power-generating power can reach 3-4W/m , and the industrial application value is large.read more
