Novel hybrid ocean thermal energy conversion system

Abstract

The invention discloses a novel ocean thermal energy conversion system. According to the system, an ammonia water mixture is adopted as a circulating working medium, and a gas-liquid separator, a heatregenerator and a heat absorber are additionally arranged. Temperature difference exists between deep-layer cold seawater and surface-layer warm seawater, the warm seawater serves as a heat source ofthe system to heat the working medium with a low boiling point, and then the working medium is enabled to evaporate and boil to push a generator to generate power; the deep-layer cold seawater servesas a cold source of the system to cool and liquefy the working medium, the processes are circulated, and power is continuously generated; in order to guarantee continuous and stable work of the generator, an ocean wind power generation device, a heat storage device and a solar heat collection device are additionally arranged; a low-speed shaft of a wind turbine and a low-speed shaft of a steam turbine are combined in a step-up gear box, and power is transmitted to the generator for power generation after speed increase; and a wind gauge and a wind speed control device are additionally arranged on the step-up gear box, and when the wind speed changes, the control device can control the tooth pitch of a gear, so that continuous and stable power generation of the ocean thermal energy conversion system is guaranteed, the thermal efficiency of power generation of the system is greatly improved, and the sea area application area of the system is also enlarged.
