Technical field

The utility model relates to prime mover device that the instant storage of unnecessary industrial electric energy also can be able to be discharged its electric energy, and the big capacity that particularly can produce commercial power indirectly moves energy storage device.

Background technique

Arrival along with the auto electric epoch, earth natural environment deterioration, the temperature big rise and big fall, constantly soaring oil price, the thawing of arctic ice sheet, the insecurity of oil geopolitics, countries in the world are to more and more higher requirement for restriction of carbon emission etc., all all pass out fuel sources such as a clear and definite signal-can not excess enthalpy rely on petroleum to the mankind.Only in the U.S., will consume 1,500,000,000 liters gasoline every day, and every liter gasoline can produce 2.4 kilograms carbon dioxide again, up to the present, various countries, the whole world and each big car manufactures, wholeheartedly drop into huge manpower, material resources, financial resources are researched and developed new-energy automobile, progress in the past few years shows: unique renewable energy sources that can reduce CO2 emission has only electric energy, so-called hydrogen economy era does not really arrive, caused the skyrocketing of provision price in the world wide and make biofuel such as ethanol with cereal, and use biofuel such as this ethanol for reducing emission of carbon-dioxide without any help, electric energy is to use the various energy-coals, rock gas, nuclear energy, Hydrogen Energy, solar energy, wind energy etc. conversion and produce, and (being at present Chinese domestic main power generation mode) of using thermal power plant to send drives electric automobile during traveling, every kilometer also only can be brought 0.2 kilogram of emission of carbon-dioxide, only be to use gasoline orthodox car 70%, from economic angle, also be 1/4th of gasoline automobile with regard to present electricity price and oil price.

From the market of in recent years electric vehicle, can see, various countries and each big automobile vendor have released the electric vehicle of many types successively, and production technology improves constantly, the also corresponding startup of Fu Wu conveyance system for it, in the energy-saving and environment-friendly automobile of releasing, no matter be the hybrid vehicle (HEV) of " transiens ", or the automobile of pure power drive mode (EV), all be subjected to the guiding of various factors restriction-government in various degree, the manufacture cost of electric vehicle etc., affecting indirectly popularizing and development of energy-saving and environment-friendly automobile, however main, most critical and the most insoluble problem then are the core component-batteries of electric vehicle.

No matter be bulky lead-acid battery, or Ni-MH battery, or be the excellent lithium ion battery of present performance performance, still all be difficult to break through battery capacity, manufacture cost and occupy the bottleneck that height and recharge time are difficult to keep, allow battery have pattern as the gasoline energy density, at present and even in a very long time from now on, all be difficult to realize.

Battery is equivalent to water storage tank, the energy of storing in the water storage tank, be exactly jar what of internal memory water storage, output power then is flow velocity or the flow that water is poured out in output, output power is low, for low power power device (as notebook computer) is not any problem, but just different for automobile, travels because automobile needs the high-energy input just can be driven.

Though each a part of automaker attempts the method for multiple lifting battery storage energy at present, reduce battery quality and manufacture cost, but these effort are all unsatisfactory, to from current research basis, realize again breaking through, remain very something of difficulty, if making the charge storage ability of battery more win gasoline one raises, just must must be cheap as fossil fuel, powerful and reliable, and to show generally better, in other words, must break through existing design concept and research mode, allow weigh up to a hundred kilograms battery be equivalent to several gasoline that rise.

The existing way of energy has multiple, aspect macroscopical, be in tellurian energy initial source is arranged: sunlight, geothermal power etc., wherein, luminous energy from the sun is the main source mode of energy, shine the sunlight total energy flow that tellurian sunlight is intercepted and captured by the earth, reach 178000 terawatt (TW)s every year, part solar radiation is scattered in the way by earth atmosphere, a part is absorbed, the solar radiation quantity that enters the earth wherein has 30% approximately through cloud layer, dust and ground are reflected and leave the earth, have 70% to be absorbed approximately by the earth, the radiation energy that absorbs has 83000 terawatt (TW)s nearly to form the sensible heat of air and water, 41000 terawatt (TW)s then become the latent heat of the earth surface evaporation of ocean and humidity, and the latent heat of steam is to discharge at last in condensation in these atmosphere, and absorbed solar energy finally leaves the earth with the form of infrared radiation, it is annual that the energy of 100 terawatt (TW)s is arranged approximately is that plant becomes biological energy source by photosynthesis, the food that the human and animal directly consumes account for wherein 1%.

From the energy system of macroscopic view as can be seen, be that tellurian air and water come the balance huge energy, by means of the sensible heat of air and water with flow, by means of the entrained latent heat of the variation of this material physical aspect, maintaining the balance of each interregional energy system of the earth, rely on these two kinds abundant, clean flowing materials of water and air, realize the storage of energy, keep each interregional temperature balance of the earth.

The circulation of the physical energy of huge cleaning, be accompanied by the storage and the release of energy, promptly there are the transmission and the conversion of energy, impel this circular flow and carry the i.e. participation of energy throughout, thus, just containing huge pollution-free energy in the water of occurring in nature and air, is to utilize the variation of physical aspect of air and water and stored energy, and they are occurring in nature crudes, be the natural storage of natural energy, be the earth the cleanest take can working medium.

Steamer utilizes the physical property of water and physical aspects change thereof and carries energy, by being the mechanical device of power source with steam, the conversion and the transmission of energy have been realized, the physical property of water is fully utilized, all realize running by means of its (water vapour) to such an extent as to the coal of today, nuclear energy, rock gas are steam turbine or the turbo machine in the power station of leading, the conversion and the transmission of energy are constantly carried out in circulation.

H2O is the transparency liquid of colorless and odorless at normal temperatures, has certain volume, does not have fixed shape.When temperature raises, H2O can be changed into steam, also can be changed into ice (actual is exactly that energy is dominated and the process of variation), the boiling point that H2O depresses at normal atmosphere is 100 ℃, during freezing point 0 ℃, in the H2O of fixed capacity, the water vapour that is produced volume under atmospheric pressure is 1800 times of liquid H2O volume, promptly the water of a constant volume is heated and becomes steam, normal atmosphere is depressed, and 1800 times of liquid H2O volumetric expansions also just are being based on the energy mode of taking that it has simple good physical property, just can finish the conversion of energy by certain machinery, this is by the physical property decision of water.

From microscopic fields: 1. kinetic energy between molecule or atom-show as thermal motion between molecule or atom, the change of physical aspect-solid-state, liquid state and gaseous state only take place, the empty qualitative changeization, other materials generally undope, during Conversion of energy, the mechanical condition that need keep is fairly simple, and the controllability of transformation of energy is strong, and surrounding environment is not exerted an influence; 2. two or more material combines, produce chemical reaction and can absorb or discharge chemical bond energy, in the process of chemical reaction, there is new compound to occur, for example carbon dioxide or sulfur dioxide, behind these compound savings, meeting failure energy or balance of ecosystem, cause tangible negative effect to environment, the internal-combustion engine that generally uses is exactly the representative of typical machine transducing head at present, and the controllability difficulty of chemical reaction is bigger, has reversibility reaction, and the condition that the chemical bond energy of the generation of chemical reaction is converted to mechanical energy is comparatively complicated; 3. atomic energy: be divided into nuclear fission and nuclear fusion; when releasing energy; be accompanied by the variation of nuclear mass; produce new material by the nuclear physics reaction simultaneously; and the fission reaction meeting produces the more reflective substance and the nuclear radiation ray of crisis health safety; the safe operation that needs numerous and jumbled physics and chemical technology to keep nuclear reactor; and the energy that nuclear fusion needs fission reaction to produce starts; but the controllability difficulty of nuclear fusion reaction is bigger; possesses the nuclear fusion technology though there is part country to claim; but existing nuclear fusion technology is still not mature enough, still has a long way to go from using.

Now comparatively urgent degree has been arrived in the pursuit of battery manufacturing technology of future generation, after all in last century and even period more early, electric vehicle has just appearred, in the expectation that people constantly promote the electric automobile during traveling mileage, people also have higher requirement to the driving comfortability of electric vehicle, to the environment-friendly and energy-efficient technology requirement is implacable in a very long time, puts in the middle of the research and development of electric vehicle although there is substantial contribution to press.

The whole process of batteries of electric automobile research and development, experienced for a long time, although from early stage lead-acid battery, Ni-MH battery afterwards, until present lithium ion battery, all endeavour the moon at battery, research and develop improvement on anode and the electrolyte, but realize not full maturity of breakthrough design and products thereof, realize breaking through from " present situation " desire, even having revolutionary thinking does not occur, battery technology is a technology heavy in hand, each inside battery all has the chemical reaction molecule or the atom that chemical energy can be transferred to electric energy that carry of million number of stages, electrolytic solution in the battery is being played the part of important bridge tie effect between both positive and negative polarity, battery is when charging, redox reaction takes place, corresponding ion is in the anode and cathode of returning battery through external circuit, be driven by external electric energy, again electric energy is absorbed, transferring chemical energy to stores, begin to circulate discharge process next time, but problem is: up to the present, the reactive ion that million number of stages are arranged in the electrolytic solution of battery, the reactive ion of these million number of stages constitutes unlimited numerous and jumbled molecular balance system, its controlled difficulty is bigger, and its number of times that effectively back and forth charges is still limited, thereby causes cell degradation, and its life-span is also limited.

In addition, the instant electric power that produces in power station or power station will cause electric energy to run off in vain if the phenomenon of excess enthalpy can't store immediately.

The enlightenment of mentality of designing of the present utility model is as follows:

Air is the same with water vapour, be rubber-like gas, cover to even air earth surface, mainly form by nitrogen and oxygen, also contain a spot of other gas such as carbon dioxide and inert gas, wherein, the major part that the pneumatolytic of nitrogen duty divides, its aerial content is 78%, oxygen takes second place, and about the 22-23% of duty gas total amount, air can be made into liquefied air after multistage compression and condensation, equally, mainly becoming of liquefied air also is liquid nitrogen and liquid oxygen, and the boiling point of liquid nitrogen is-195.8 ℃, and liquid nitrogen contains a small amount of miscellaneous affair and is weak yellow liquid, the industrial production cost of liquid nitrogen is very low, and price is for also only being 0.7 yuan/liter.In addition, the preparation technique of existing liquid nitrogen is quite ripe, the liquid nitrogen producing equipment is also fairly perfect, and the application that liquid nitrogen is commonly used at present is refrigeration, synthetic ammonia, chemical industry, medicine and scientific research etc., and N2 is the very stable element of a kind of chemical property, the storage of liquid nitrogen and transportation have perfect equipment and technology, normal temperature is the insulation stable storage down, and is also very safe, in general, as long as safety technique can guarantee, can not take place to cause (expansion) blast and physical expansion blast by chemical reaction.

Producing in the process of liquid nitrogen, when atmosphere is compressed through electrically driven (operated) multistage compressor, be condensed and discharge outside a large amount of heats, the a large amount of industrial electric energy that needs to keep Driven Compressor running work (also can provide energy for compressor with other power, but industrial production still is main finishing with the electric energy at present), multistage compressor makes the dynamic power of using up be directly proportional with the yielding capacity of liquid nitrogen, and the yielding capacity of liquid nitrogen is big more, and the electric weight that multistage compressor is used up is also many more.

At this moment, with new visual angle liquid nitrogen is analyzed, according to the law of thermodynamics, it contains energy, it is negativity energy with respect to normal temperature, nitrogen is by the variation of the physical aspect of self, after having discharged heat energy, the material that possesses powerful absorption heat energy, the liquid nitrogen that liquefied by enrichment this moment has held the industrial electric energy that storage is arranged in fact, it can be by certain intermediary's mechanical body (nitrogen power engine), the negativity of this part of finishing it under certain conditions can release, nitrogen drains in the atmosphere again, get back to its normal temperature once more, normality under the normal pressure (gaseous state) has been finished its indirect storage of electrical energy immediately to exergonic process, and this is the core technology content of the utility model patent.

According to intramundane relativity, the water vapour that is higher than 100 ℃ contains the energy that makes water change physical aspect, the characteristic of apparent water has determined that this process is the transfer process of a positive performance, for normal temperature, is the supply that needs additional thermal energy, can realize, the energy that water vapour carries is in transfer process, and the heat transferred atmosphere that discharges, the entropy in the atmosphere are always increasing, but with respect to air, the cyclic process of the negativity of nitrogen energy is more simple and easy to do.Liquid nitrogen is in producing process, it is after multistage compression, under high temperature, high pressure after condensation, reduced intermolecular kinetic energy (heat energy), the heat transfer that discharges is to atmosphere, when releasing energy, liquid nitrogen absorbs sensible heat in the atmosphere and the vaporization of seething with excitement once more, formation is in accumulating of pressure state the band merit normal temperature liquid of pressure energy (by ultrahigh pressure liquefaction storage), and subsequently, the pressure of liquid nitrogen can be realized the release to electric energy by machinery.More than the negativity of the positive performance transfer process of said water and liquid nitrogen can transfer process, one is that the water heating changes over the gaseous state form and stores positive performance, one is to change into liquid state after the nitrogen compression and store the negativity energy, the positive performance transfer process of water and the negativity of liquid nitrogen can turn over the accumulation of energy mode that journey is two kinds of opposed polarizations, and can turn over journey for the negativity of liquid nitrogen, the circulation of air promptly is that entropy is constant or utilize the cyclic process of this part entropy, so it is cold and hot with respect to normal temperature, it is the form of expression that energy is different, but for the intermediary's fluid that carries energy (being water vapor or liquid nitrogen), the just variation of water or liquid nitrogen physical aspect.

Air is resilient object, release heat becomes liquefied air after multistage compression, it has negativity can, be with respect to the atmosphere sensible heat, can absorb the negativity energy, the liquid nitrogen of one constant volume absorbs airborne heat (sensible heat in the normal temperature atmosphere) and seethes with excitement afterwards and become gaseous state, at normal temperature, its volume significantly expand hundreds of times (above 600 times) under the normal pressure, be higher than this temperature (such as the normal temperature meeting) boiling, if in seal container, liquid nitrogen is heat absorption constantly all, and boiling is vaporized and storage pressure energy, can finish the conversion of energy by machinery, thereby give off energy, airborne nitrogen can be by enrichment, liquefaction and storage negativity energy, with indirect mode realize energy storage and release can energy system circulate principle that the utility model adopted that Here it is.

According to the law of thermodynamics, heat always passes to cryogenic object from high temp objects, can not do reversible transmitting movement, do not follow other variation (acting) yet, in exoergic process, the temperature of liquid nitrogen is much lower for normal temperature, so what greatly the temperature difference allowed it possesses is powerful thermal absorptivity, the same as water vapour with the thermal conductivity of water, an amount of liquid nitrogen is in liquid nitrogen pump is pressed into (pipe type) vaporizer that is in airtight normal temperature state, the huge temperature difference makes the liquid nitrogen vaporization of seething with excitement rapidly, the nitrogen gas generation pressure of continuous vaporization, this moment, the pressure of nitrogen air reservoir just can promote nitrogen power engine (steam-driven generator for example, steam turbine) or air pressure piston type engine running (technology of steam turbine or air pressure piston type very ripe), so that the energy that the nitrogen power engine is produced is released continuously, at last, nitrogen directly enters in the atmosphere, finish primary air from compression, separate, the storage liquid nitrogen, the entire flow of release pressure energy, liquid nitrogen is become carry heat absorbing property De Changwen working medium, when needing, liquid nitrogen carries out heat exchange by " boiler of heat exchanger " (being the heat exchange vaporizer) and air, " boiler of heat exchanger " makes air cooling-down, makes liquid nitrogen gasification rise to normal temperature.

The technical solution of the utility model is exactly the bottleneck of the existing battery technology of the every restriction of Gonna breakthrough, allow battery reach the energy density similar with gasoline, allow the performance of electric vehicle that revolutionary lifting is arranged, go through the demonstration repeatedly in several years with to the development of electric vehicle, looking around of battery technology, after the contrast, determine to upgrade the necessity of existing theory more.

Its machine work process of the utility model is different from " hot machine ", it is under normal temperature or the working state a little less than normal temperature, can be applied to existing automobile or power station (factory) as automobile, and utilize liquid nitrogen release can the time refrigerating effect, can give air cooling-down, can give lowers the temperature in the automobile car plays the effect of air-conditioning, perhaps in the power station (factory), can attach refrigeration plant, industries such as grain nitrogen warehouse, " self-excitation " link that then needs a liquid nitrogen in the winter time, this just needs a part of electric energy that generator sends as " thermal source "-the finish self-excitation of liquid nitrogen and the work of automotive air conditioning system, the volume expansion ratio of raising liquid nitrogen-nitrogen.In sum, the utility model can store the excrescent electric power of traditional contamination type power station (station) or new energy environmental protection power station (station) generation, convert the pressure energy to and store, in order to needing under the situation of electric power in instant generating electric weight deficiency or at other, the energy of its storage is discharged, supply with electricity consumer, to play the effect of electric power supply, when releasing energy, pollution-free, can realize the zero-emission of carbon, utilize simultaneously in the process that releases energy the refrigerating effect of air, can near power station (station), build facility or the factory building relevant, significantly improve the utilization ratio of cold energy efficient in the exoergic process with the refrigeration industry, convenient mobile dismounting, perhaps can make the traffic tool emission-free, zero-emission with its miniaturized application to the traffic field, utilize refrigerating effect simultaneously, play effect air temperature modification in the car to air.
