Embodiment Construction

[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0023] The high-efficiency ocean temperature difference energy power generation system provided by the present invention adopts a hybrid circulation system, which is transformed from an open circulation system on the basis of a closed circulation system. It can generate electricity and fresh water, and has both open circulation and closed circulation. Advantages of the cycle. The system uses solar pools to heat warm seawater, and uses concentrating solar collectors to increase the temperature of its working fluid, thereby improving power generation efficiency.

[0024] Based on the above principles, the specific implementation of the present invention can be found in figure 1 ,

[0025] The whole system is mainly composed of solar pond 3 , deg...

Abstract

The invention discloses a high-efficiency hybrid ocean temperature difference power generating system. When the system works, warm sea water is pumped by a warm water pump to pass through a solar pond, and heated by solar radiation; the heated sea water enters a degasser for degassing, enters a flash evaporator for flash evaporation, and then enters a focusing solar thermal collector to continuously raise the temperature; and overheated steam enters a steam turbine for doing work in an expanding way; cold sea water is pumped into a condenser by a cold sea water pump; and the cold sea water with raised personal temperature flows back to the sea to continuously cycle. The system is suitable for coastal towns, islands and marine engineering, and achieves the effects of saving electric energy, and making full use of ocean resources.

Description

Technical field: [0001] The invention relates to a device for generating electricity by using ocean energy, in particular to a hybrid power generation system for efficiently generating electricity by using ocean temperature difference. Background technique: [0002] Energy is the material basis for the existence and development of human society, and ocean energy is an important part of new energy and a renewable energy with huge reserves. Seawater temperature difference energy is an important ocean energy, which is renewable, clean and pollution-free, and has abundant reserves. It refers to the energy of the difference in water temperature between the surface seawater and the deep seawater of the ocean. This temperature difference can be used to realize a thermodynamic cycle and generate electricity. The hybrid seawater temperature difference power generation system combines the common advantages of closed cycle and open cycle. It can not only generate electricity, but als...
