Description

Solar ammonia water thermoelectric conversion system
Technical field
The present invention relates to a kind of solar ammonia water thermoelectric conversion system, belong to the solar energy light heat generator technical field.
Background technique
Solar energy is meant the radiation energy of sunlight.The nuclear reaction by " hydrogen " fusion one-tenth " helium " in that solar interior carries out ceaselessly discharge huge energy, and constantly to the cosmic space radiation energy, this energy is exactly a solar energy.Solar energy is a kind of green, cleaning, the inexhaustible energy.Human just have three kinds substantially to the solar energy utilization: solar energy optical-thermal, photoelectricity and photochemical transformation of energy, and the conversion regime that is used to produce electric power has only the transformation of solar energy optical-thermal and photoelectricity.The form of photoelectric conversion is more single, and the main form of utilizing is a solar cell.The conversion regime of solar energy thermoelectricity and its apparatus are just many.A principle the most common of the thermoelectric conversion of solar energy is exactly to manage to obtain water vapor by the collection of solar energy, by the steam turbine acting, drives generator and produces electric power.
What routine solar light-heat power-generation system used all is the high temperature solar resource.The reason of the main use high temperature heat source of high temperature solar power generation system is that its turbine power generation unit is a conventional Rankine circulation power system, in order to guarantee its heat-economy, just must improve the initial temperature and the pressure of thermodynamic cycle.Solar energy resources is the lower resource of energy density, and this must assemble the energy of low energy densities by special device with regard to causing conventional solar light-heat power-generation, thereby can provide enough heats to add hot water, obtains the water vapor of High Temperature High Pressure.Such as the solar energy tower type generating, slot type generating etc. all need to drop into huge fund and build solar aggregation apparatus.Below just introduce several frequently seen solar light-heat power-generation system.
One, tower type solar power generation system
This system sets up tall and big tower on spacious level land, cat head installs and fixes a receiver and is equivalent to boiler, the heliostat that the disposed about of tower is a large amount of is assembled sunlight and reflexes on the receiver of cat head producing high temperature, and the high-temperature steam pushing turbine that generates in the receiver generates electricity.
Tower type solar energy thermal power generation can be divided into two kinds again by the difference of heating working medium, and a kind of is the heating pure water, another kind of for adding hot brine solution.
In salt tower type solar heat utilization power station, thousands of day mirror with solar light focusing to the heat absorber of high building top, heat changes the saline solution in the heat absorber over to, its temperature is elevated to 565 ℃ from 265 ℃, pyrosol is delivered in the hot salt storage then, produces steam by steam generator, after the steam turbine acting, get back to again in the cold salt storage after the condensation heat release cooling, squeeze in the heat absorber once more after boosting by the salt solution pump.
Although the starting of tower type thermal generation system early, people also wish by heliostat as much as possible solar energy to be gathered the level of tens megawatts always, but the cost of tower system is high always, and industrialization is difficult, and its basic reason is the design of heliostat system.The reflective surface that it is heliostat that the heliostat of at present typical tower type thermal generation system all has two characteristics one nearly all adopts common sphere or plane, and the 2nd, the traditional elevation angle, azimythal angle formula is all used in the tracking of heliostat.These two design features cause tower type solar optically focused receiver to exist the following problem that is difficult to overcome:
The first, the sun presented variation significantly at the hot spot that focuses on the tower within one day, caused the optically focused light intensity to fluctuate widely, and common sphere or planar mirror can't overcome the aberration that produces owing to solar motion.Because the card effect of the sun, the spot size that each reflector forms on central tower is along with the distance of it and central tower increases and linear growth, on the tower the last solar focusing hot spot that forms within one day can with the size of heliostat field from several meters change to tens meters big, so fluctuating widely appears in tower type solar energy thermal power generation station light light intensity.Add the different cosine effects of each heliostat, the photo-thermal conversion efficiency of tower system only is about 60%.Although at present in the design of some tower systems of relatively being particular about, the sphere that different heliostats is begun to adopt different curvature radius to be reducing the size of sun focal beam spot on tower, but the optical design complexity increases greatly and causes manufacture cost also and then to increase substantially.
The second, numerous heliostats is set up around central tower, and the foundation of the central tower that floor space is huge must guarantee can not stop light mutually between each heliostat.Distance between each heliostat increases substantially along with the increase of they and central tower distance, thereby the floor space of tower type thermal generation system is index and increases sharply along with the increase of power level.
Because above-mentioned these problems although the tower type thermal generation system can realize 1000 ℃ focusing high temperature, are faced with the excessive problem of unit installed capacity investment always.The initial cost cost of tower system is 3.4 ten thousand~4.8 ten thousand yuan at present, and the cost reduction is very difficult, does not promote so tower system rests on demonstration phase over more than 50 year all the time and comes.
Two, groove type solar power generation system
This system a kind ofly reflexes to solar light focusing on the heat build-up pipe by the flute profile parabolic mirror, water is heated into the clean energy resource utilized device of steam pushing turbine generating by heat carrying agent in managing.The power in flute profile parabolic solar power station is 10~1000MW.Trough type solar power generation is prominent in present all solar energy thermal-power-generating stations.The heat transfer that system's heat collector collects is to the interior heat carrying agent that flows of pipe, heat carrying agent can be water vapour, deep fat or salt solution etc., used reflector is made by poor iron glass, and enough accuracy of manufacturing must be arranged for it so that sunlight reflection effectively under any circumstance.
The reflector that the flute profile parabolic solar collector is adopted is parabolic post.Sunlight reflected focuses on point-blank, the vacuum tube glass heat collector that is placed on the focal line absorbs the solar radiation that is focused, temperature can reach 400 ℃, high temperature heat-carrying matter heats the water generates water vapor in Intermediate Heat Exchanger, self temperature descends, flow back to the solar thermal collector heat absorption by heat-carrying matter recycle pump, constitute thermal source one loop.The water vapor that produces is the turbine acting in steam turbine, drives generator for electricity generation, and exhaust is condensed into water in condenser, after condensate pump and feed water pump boost, returns Intermediate Heat Exchanger again, continues circulation, and this constitutes second loop.
The slot type system has replaced the pipeline of point focusing and focusing along with the cylinder parabolic mirror is followed the tracks of solar motion together with linear focusing, with regard to having solved the not high problem of photo-thermal conversion efficiency that tower system causes owing to focal beam spot is inhomogeneous, photo-thermal conversion efficiency is brought up to about 70% like this.It is the tracking that can't realize under the fixed target that but the slot type system also brings a new problem, causes the system mechanics heaviness.Because the focusing pipeline in the middle of the solar receiver is fixed on the slot type reflector, along with each slot type reflector of reflection all is a big whole minute surface of length and width, windage is very big, the supporting structure that must change or add intensive reflector must cause initial cost cost and hot cost of electricity-generating to increase to increase the wind resistance of slot type system like this.
The receiver of slot type system is long, and heat diffusion area is big, and the solar receiver of slot type system is the very long heat absorption tube of root, although developed many new extinction technology.But its heat radiation comprises that the heat diffusion area that is caused by thermal radiation is bigger than its effective light-receiving area, therefore compares with tower with a type focusing system such as dish formula, and the heat loss of slot type system is bigger.
Three, disc type solar energy power generation system
The parabolic mirror that the disc type solar energy power generation system is made up of mirror more than 2000 is formed.Receiver is guided to 600~2000 ℃ the thermal source of collecting in the Stirling engine on paraboloidal focus, and heat-transfer working medium is heated to about 750 ℃, drives generator at last and generates electricity.The dish reflector is followed the tracks of sun's motion and is moved, and has overcome the loss problem of the big cosine effect of tower system, and photo-thermal conversion efficiency improves greatly, generally up to about 85%.
Dish formula receiver with solar focusing on the focus of the paraboloid of revolution, again because solar concentrator and Stirling engine can be extraordinary in conjunction with producing electric energy, it is that the net efficiency of electric energy can reach 29.4% with solar energy converting, is most effective in all solar electrical energy generations so Stirling circulates in the identical temperature range of operation.The disc type solar energy power generation system is used flexibly, both can make distributed system and power separately, also can generate electricity by way of merging two or more grid systems.
Being compared as follows shown in the table of disc type solar energy power generation system and groove type solar power generation system and tower type solar power generation system:
Tower Slot type The dish formula
Operating temperature (℃) 500-1000 260-400 500-1500
Sun light concentrating times 600-1000 8-80 200-3000
Photo-thermal conversion efficiency (%) 60 70 85
Cost of investment (the hybrid system generating that solar energy and other dyestuffs are formed) (ten thousand yuan/KW) 3,4 2,2 4,7
Cost of investment (using solar electrical energy generation separately) (ten thousand yuan/KW) 4,8 4,4 6,4
By this table as can be known, disc type solar energy generating operating temperature and optically focused are than being maximum, and its photo-thermal conversion efficiency ranks first at the similar system meta up to about 85%.The shortcoming of dish formula system is to involve great expense, and also is to occupy the first place in this system.The initial cost cost of dish formula heat generating system is up to 4.7 ten thousand~6.4 ten thousand yuan at present.The optically focused of pipe-dish type system is higher than very to the greatest extent, can reach 2000 ℃ high temperature, but high temperature like this does not need or even has destructive for present hot generation technology.So, the receiver of dish formula system generally is not placed on the focus, but require suitably to be placed in the lower humidity province according to performance index, in fact the advantage of high like this optically focused degree can not be fully played and the thermmal storage difficulty, and hot melt salt heat-storage technology is greatly dangerous and cost is high.
In sum, existing three kinds of solar light-heat power-generation technology all belong to the high temperature solar generation technology, this has just increased the solar thermal collector performance demands greatly, also just certainly will increase the fund input at the solar energy heating apparatus, has increased initial investment.
