Title:
SYSTEM AND METHOD FOR PERFORMING SEAWATER DESALINATION BY USING HEAT SUPPLY BACKPRESSURE STEAM TURBINE GENERATOR UNIT
Document Type and Number:
WIPO Patent Application WO/2023/197596
Kind Code:
A1
Abstract:
A system for performing seawater desalination by using a heat supply backpressure steam turbine generator unit (1). The system comprises a heat supply backpressure steam turbine generator unit (1), a heating network system and a seawater desalination system. In a non-heat supply period, heat supply extraction steam works in a heat supply backpressure steam turbine generator unit (1) and then becomes low-temperature steam, and the low-temperature steam enters a desuperheater (2); by means of closed-loop control over the temperature, it is ensured that the temperature of steam at an outlet of a desuperheating water header tube (5) at an inlet of a seawater desalination apparatus is 65-70°C, and the steam then enters the seawater desalination apparatus; and the steam is subjected to seawater desalination in the seawater desalination apparatus, so as to obtain fresh water, and waste water is also discharged. Further disclosed is a method for performing seawater desalination by using a heat supply backpressure steam turbine generator unit (1).
