Description
Technical field
The utility model relates to a kind of temperature difference electricity generation device, especially utilizes the temperature difference electricity generation device of the material of two kinds of low evaporating temperatures, high saturation vapour pressure as working medium.
Background technique
At present, adopt coal, oil, rock gas, nuclear energy etc. to transform power generation system as the heat-electricity of heat energy, all be to use one matter water as working medium, at first water is heated vaporization in boiler, become high temperature and high pressure steam, again high temperature and high pressure steam is sent into steam turbine, the pushing turbine rotation, steam turbine drives generator for electricity generation, finishes whole heat-electric conversion process.Because the water evaporating temperature is higher, need expend a large amount of energy so that it becomes steam, be disadvantageous to human kind sustainable development.
Latter half in 19th century, the Frenchman proposed ocean thermal energy conversion, and the professor of Uehara Shuno in Japanese Saga University marine energy research center studied since 1973.His ocean thermal energy conversion of research is the mixed solution that utilizes ammonia and water, and as the steam that drives turbo machine, because compare with boiling point 100 degree of water, the boiling point of ammoniacal liquor is 33 degree, boiling easily.
This system utilizes vaporizer to make the mixed solution boiling by the heat of surperficial seawater, drives turbine generation with the ammonia steam.Can be cooled off by deep sea water after the ammonia steam acting generating, become liquid again.So circulation is generated electricity.
The power of ocean temperature differential power is to determine by the temperature difference of temperature end seawater flow and high low temperature seawater is big or small, the high low temperature seawater temperature difference of existing ocean temperature differential power device (working medium is in the temperature difference amplitude of evaporator end and condenser end outlet) is generally about 25 ℃, difficult formation is high temperature difference more, therefore if improve temperature difference electricity generation device power, can only increase the temperature end seawater flow by acting, this operating cost to whole device is disadvantageous.In addition, after the working medium of existing apparatus entered condenser cooling, by working medium compression pump Returning evaporimeter again, this made the power generation system inefficiency, in this process, can carry out preheating for the working medium that enters vaporizer the generating working medium part of waste heat after deliberation, improve generating efficiency.
Summary of the invention
In order to overcome existing ocean temperature differential power device operating cost height, inefficient situation, the utility model provides a kind of temperature difference electricity generation device, this device adopts the material of two kinds of low evaporating temperatures, high saturation vapour pressure as working medium, not only improved the temperature difference amplitude of working medium in evaporator end and condenser end outlet, the waste heat that has also reasonably utilized acting back working medium carries out preheating to the working medium that enters before the vaporizer, whole temperature difference electricity generation device efficient is improved greatly, help the popularization of ocean temperature differential power.This device not only is suitable for use in the natural marine site of big temperature difference seawater, also is particularly suitable for being applied in the occasion of a large amount of waste heats, as: power plant, factory.
The technological scheme that its technical problem that solves the utility model adopts is: device is made up of parts such as steam turbine, generator, condenser, working medium booster pump, liquid container, expansion valve, vaporizers, form two working medium loops, can be described as generating working medium loop, cooling working medium loop.Two kinds of working medium can be respectively the material of low evaporating temperature, high saturation vapour pressure, as: ammonia, freon (R134a), nitrogen, carbon dioxide etc.
In the generating working medium loop of device, inject liquid refrigerant in the liquid container, open expansion valve, liquid refrigerant enters condenser or heat exchanger of establishing in addition and the working medium of discharging from steam turbine are carried out heat exchange, enters vaporizer after the heat exchange, and high temperature seawater is passed to working medium with heat in vaporizer, working medium evaporation rapidly becomes the high-pressure gaseous expansion, gaseous working medium is through entering steam turbine, and pushing turbine rotates, and drives generator for electricity generation.Working medium acting generating back air pressure step-down, the heat exchanger that enters condenser or establish in addition, cryogenic fluid is cooled to the liquid state of lower temperature in the cooling working medium loop of the device opposite side that is condensed again, turns back to liquid container by the working medium booster pump again; Working medium enters into the cooler in this loop in the cooling working medium loop after condenser is heated, and outwards dispels the heat by wind or water, returns the working medium jar afterwards, enters condenser once more through working medium circulating pump, so circulation.Finish the whole generating process.
The beneficial effects of the utility model are that this electricity generating device can make full use of the cooling residual heat of power generation circuit working medium when working, improve generating efficiency, and can improve the temperature difference amplitude of power generation circuit working medium in evaporator end and condenser end outlet, improves generated output.
