An ammonia turbine device for ocean temperature difference power generation

Abstract

The invention relates to the technical field of turbines, and discloses an ammonia turbine device used for ocean temperature difference power generation. The ammonia turbine device comprises a turbine body, a flow way system, a seal system, an oil path system, a shaft system and a power generation system; the flow way system is located on one side of a turbine and comprises a volute, a nozzle, an impeller and a pressure expander; the shaft system comprises a turbine spindle, a bearing and a coupler; the power generation system comprises a power generator and a rectifier and inverter system; the seal system comprises a movable seal component and a fixed seal component; the movable seal component adopts double-end-face mechanical seal; the oil path system comprises a seal lubricating oil path, a bearing oil film oil path and an electric generator heat dissipation oil path; the seal lubricating oil path and the bearing oil film oil path are pressure oil paths; double-end-face mechanical seal is adopted, the pressure oil paths are matched, zero leakage of ammonia working media is ensured, the tilting-pad bearing is adopted to ensure high-speed rotation and axial thrust of the shaft system, and finally through optimized integration of all components, efficient and stable running of the turbine can be ensured.

Description

technical field [0001] The invention relates to the technical field of turbines, in particular to an ammonia turbine device used for ocean temperature difference power generation. Background technique [0002] With the world's population growth and economic development, the rapid growth of energy demand has led many countries to look for non-traditional energy sources, such as solar energy, ocean energy, wind energy, etc., to obtain multiple energy solutions. Ocean temperature difference energy is considered to be one of the most potential energy sources due to the combination of ocean energy and solar energy, and ocean temperature difference energy power generation has the advantages of hardly emitting carbon dioxide and obtaining fresh water, so it may become a solution to global warming and water shortage. An effective approach to the biggest environmental problems of the 21st century. [0003] The ocean temperature difference energy power generation system is a system t...
