Description
One, technical field
The invention belongs to technical field of power generation, belong to the method and the device that utilize air energy, ice-cold energy, solar energy or thermal gradient energy etc. to generate electricity especially.
Two, background technique
The technology close with the present invention is " solar pond heat generating system " (drawing from " generation of electricity by new energy technology " China Electric Power Publishing House).Solar pond comes down to a salinity and has certain density brine pit.The lighter fresh water of one deck is possessed on top, pond, and the bottom is heavier salt solution, makes keeping certain salinity gradient along the vertical direction of solar pond.The visible light of sunlight and ultraviolet part can see through several meters dark peace and quiet water, and this part radiation energy will be absorbed by the dark bottom in pond.Because the water purification body is a well effective heat insulator, therefore, the water of the bottom of the solar pond of good design may seethe with excitement owing to continuous heat absorption.Must avoid this boiling, this is because water is in case boiling will damage stable density gradient in the pond at the bottom of the pond as far as possible.So, when being designed for the solar pond of various solar heat utilizations and heat generating, must accomplish effectively to carry out the transfer of a large amount of useful heat, and water seethes with excitement at the bottom of can avoiding the pond conscientiously.
Solar pond can not adopt the heat exchange pipe network of different working medium to carry out heat exchange.Thermodynamic principle point out, fluid layer can slowly be removed at the bottom of the pond and not upset the water body main body.So just can at the bottom of the pond, extract heated salt solution out, after the heat exchanger heat exchange, send back at the bottom of the pond again with pump.Because the fluid temperature (F.T.) that the fluid ratio that refluxes is extracted out is low, therefore can accomplish the salt solution of heating is extracted out at the bottom of the pond, keep needed density gradient in the pond simultaneously and unlikely disturbed sun pond proper functioning.
Using the above-mentioned characteristic of solar pond, solar pond is built up in the bittern lake, is exactly a huge flat plate collector.Utilize it to absorb solar energy, produce superheated vapor by the heat exchanger heats low boiling working fluid again, drive the Turbo-generator Set generating, the principle of solar pond that Here it is heat generating.
Israel Ao Ermate steam turbine company has built maximum in the world solar pond power station on dry lake, California, USA Dong Shengbainadinuo area, its total clean generated output is 48MW, first group of 12MW unit and putting into operation in 1985, put into operation in December, 1987 in the bed rearrangement power station.
There are four salinas in this power station, 48 * 1000 square metres of each areas, and dark 3.6 to 4.8 meters of pond can be for 1 to 2 group of Turbo-generator Set generating.After brine at the bottom of the pond was heated by sunlight, temperature can reach 93.3 degree.With pump brine is extracted out,, made it vaporization, produce superheated vapor, drive the generating of low boiling working fluid Turbo-generator Set by heat exchanger heats fluorine Lyons.The steam that steam turbine is discharged is after vapour condenser condenses, and Returning heat-exchanger heats again.System's running temperature can reach 82.2 degree.This power station is built and is managed by the design of Ao Ermate company, and the electric energy of generation is sold California Edison's electrical network.
This technology belongs to the exploitation Demonstration Application stage at present.Need certain region restriction owing to build solar pond, can only be in the coastal or regional construction of salina, and technical difficulty is higher, and suitable big capacity generates electricity by way of merging two or more grid systems.
Because traditional fuel energy minimizing day by day, the harm that environment is caused becomes increasingly conspicuous, develop novel, cleaning, the epoch of renewable energy sources arrive.Many countries are all carrying out the research and development of this respect.And China energy demand big country especially.Therefore, the development and use novel clean energy is of great immediate significance especially.
Three, summary of the invention
Technical problem to be solved by this invention is, a kind of method of utilizing the various energy that extensively are present in occurring in nature to generate electricity is provided; Another technical problem to be solved by this invention is, a kind of device that utilizes the various energy that extensively are present in occurring in nature to generate electricity is provided.
The present invention proposes and utilize ice storage in winter or snow, treat that temperature is when higher (containing inexhaustible energy) in the air, utilize the method for the thermal gradient energy generating of air and ice or snow, started a kind of new using energy source method (required energy is ice-cold energy when defining ice or snow melt for the time being).As everyone knows, when water-setting build-ups ice, need emit heat, and when ice is molten into water, need to absorb heat, and ice and water all are accompanied by the transfer of energy when temperature raises or reduce.And ice is a kind of extensive existence and the material that is easy to store.Therefore, store ice and just be equivalent to store energy.We know by the second law of thermodynamics: (machinery that all is converted into useful work from single source absorption heat is called perpetuum mobile of the second kind).Perpetuum mobile of the second kind can not cause.Therefore, if think effectively to utilize the heat energy in air work done, just must there be corresponding with it cryogenic substance to cooperate.We do a simple computation here: by physics as can be known, it is 335KJ that 1 kg of ice is molten into water institute calorific requirement, and 1 kilogram-20 ℃ ice temperature is increased to 0 ℃, and institute's calorific requirement is 42KJ, is 84KJ and 1 kg water rises to 20 ℃ of institute's calorific requirements by 0 ℃.Suppose that we get operation interval is-20 ℃ of ice to 20 ℃ water, then: become 20 ℃ water if 1 kilogram-20 ℃ ice are heated up, institute's calorific requirement is about: 335KJ+42KJ+84KJ=461KJ.Contrast, the 1 kilogram of standard coal institute liberated heat that burns is: 29000KJ.With 29000KJ divided by 461KJ, can draw: 29000/461=62.9, also promptly: with the heat that 62.9 kg of ice absorb, liberated heat when being equivalent to 1 kilogram of coal burning, also promptly: the cold energy that stores 62.9 kilograms ice gained is equivalent to obtain the energy value of 1 kilogram coal.If build the ice bank of ten thousand metres * ten thousand metres * 50 meter, then be equivalent to obtain reserves and be: 79491255 tons colliery.In like manner, if build the ice bank of 100000 meters * ten thousand metres * 50 meter, then be equivalent to obtain reserves 800,000,000 tons large-scale colliery nearly.And China the Northeast is vast in territory, and cold season is very long, can obtain inexhaustible cold energy.If in the coastal area, then can draw the seawater ice making and store, can obtain energy, also can in generating, ice be molten into fresh water.(after seawater was freezing, the part of freezing was a fresh water, and last seawater part concentration becomes big.Thereby) solve the problem of desalination of sea water.China Bohai Sea is Liaodong Wan one ground only, and the amount of freezing naturally annual winter can reach 2.The 5*1000000000 cubic meter, can also manually manufacture ice, output can improve manyfold, (being again the very high fresh water of purity behind these ice-outs) is if be transported to the East Sea (Shanghai) or south sea area with these ice, combine with high temperature air or seawater or the known heat source system of there, form power generation system, both can solve (Shanghai) energy problem, can solve the fresh water problem again.China is one of maximum country in same latitude glacier, about 58600 square kilometres of the mountain glacier gross area, glacier gross reserves 5130*1000000000 cubic meter, as the snow mountain of Yunnan Province of China, long-term accumulated snow is not changed on the mountain, and the following four seasons of mountain are as warm as spring, if long-term accumulated snow exploitation on the mountain is got off, combine with high temperature air under the mountain or water or known heat source system, form power generation system, will obtain huge energy.And all these ice are annual recyclable regeneratives, and are environmentally friendly novel energies.
Many regional day and night temperatures very big (as the hinterland, northwest, most surpass 30 ℃, high person reaches 60 ℃) in China can adopt the phase-change material heat accumulation on daytime of different melting points, storage at night cold respectively, respectively as heat source system and condenser system composition power generation system.Material is converted into gaseous state by liquid state, or from the solid-state gaseous state that is converted into, all will absorbs heat of phase change by so attitude is converted into liquid state, will discharge heat of phase change when carrying out inverse process.Preferably, many hydratable salts or organic phase change material all can utilize.
Daytime is with the energy in solar energy or the high temperature air, heat corresponding dystectic phase-change material, make it to become liquid state, be incubated storage, be used as heat source system, get corresponding low-melting phase-change material night, with the cool air heat-shift, be cooled to solid-stately, be incubated storage, be used as condenser system, form power generation system with heat source system.
At the northern extremely frigid zones of China, winter is very long and cold, can select low-melting phase-change material for use, and is (preferred, fusing point is 0---and-35 ℃) (self-defined in order to storage of cold, at low temperatures, phase-change material is converted into solid-state by liquid state, the heat energy of release, be defined as the cold energy of absorption), in order to condenser system, optional underground water, or the water under the river, river, lake, sea ice layer or known thermal source are done heat source system and are formed power generation system.
