DESALINATION AND TEMPERATURE DIFFERENCE POWER GENERATION SYSTEM

Title:

DESALINATION AND TEMPERATURE DIFFERENCE POWER GENERATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2020/045659

Kind Code:

A1

Abstract:

This desalination and temperature difference power generation system achieves effective usage of temperature difference energy and enhances the performance of the entire system. A plurality of steam motive power cycle units are provided that cause a phase change of a working fluid to obtain motive power for power generation, and an evaporator 11 of one steam motive power cycle unit 10 is supplied with, as a high temperature fluid, steam obtained by evaporating warm seawater with an evaporating means of a seawater desalination device 60, and an evaporator 21 of another steam motive power cycle unit 20 is supplied with, as a high temperature fluid, the residual seawater not evaporated by the evaporating means, and these evaporators respectively evaporate working fluid. Thus, the one steam motive power cycle unit 10 forms a hybrid cycle, the other steam motive power cycle unit 20 forms a closed cycle, and the other steam motive power cycle unit 20: inhibits heat loss on the high temperature fluid side, thereby making it possible to ensure heat that can be effectively used; and additionally, uses residual seawater in a deoxygenation state, thereby making it possible to achieve a state in which biological fouling is unlikely to occur in the evaporator 21.
