Embodiment Construction

[0023] In order to make the technical means, creative features, realization goals and advantages of the present invention easy to understand, the present invention will be further elaborated below in conjunction with the drawings.

[0024] Based on the industrialization of ocean temperature difference power generation, improving its power generation efficiency and the reason why the generator cannot work stably due to the influence of factors such as day and night and seasons on the sea temperature difference, and considering that wind energy is the same as ocean temperature difference energy, that is, primary energy, It is also a renewable energy source, and the surface of the ocean is also rich in wind energy, and there are few periods of calm wind. Therefore, the system uses two methods of wind power generation and working fluid gasification expansion to drive the turbine blades to rotate respectively. The low-speed shafts of the two power devices are combined in the speed-u...

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.

Description

technical field [0001] The invention relates to a new type hybrid ocean temperature difference power generation system, in particular to a Kalina-11 cycle method using a mixture of ammonia and water as a working medium for generating electricity using wind energy, solar energy and ocean temperature difference energy, which belongs to the combination of mechanical engineering and new energy power generation field. Background technique [0002] Energy is the material basis supporting the progress of human civilization and an indispensable basic condition for the development of today's society. With the increasing demand for energy, human beings are also facing threats such as environmental pollution and energy depletion. Ocean energy is a kind of renewable energy stored in the ocean, with huge energy reserves, and ocean temperature difference energy accounts for the largest proportion, so the development and utilization of ocean temperature difference energy has a good develo...
