Principle of the present invention: at Yi Shui (water vapor) is in the thermal power generation process of working medium, and water will pass through preheating, evaporation, overheated three processes usually and change superheated vapor into.In above-mentioned three processes, the heat that steam superheating needs only accounts for 20～30% of total caloric receptivity usually, and the heat that the preheating evaporation process absorbs accounts for more than 70% of total caloric receptivity usually.If be placed directly in the superheating process of steam on the heat absorber and accomplish, (in the tower type thermal generation system, local heat flux density is near 1000kW/m usually because the heat absorber surface heat flux is big
2), then possibly there are several problems of following aspect in system;
Because the thermal capacitance of superheated vapor is low, density is little, heat-exchange performance poor (than common little two magnitudes of the coefficient of heat transfer of fused salt), therefore is difficult to produce the high superheated vapor of parameter, this will certainly have influence on the efficient of solar heat power generation system; If the area through increasing heat absorber improves steam parameter, will bring problems such as the increase of heat absorber area, cost increase, heat waste height;
Solar heat power generation system receives the influence of weather conditions very obvious, and parameters such as intensity of solar radiation, wind speed, ambient temperature all can have influence on the stable operation of system.Especially the cloud amount of sky is more remarkable to the influence of solar heat power generation system.The variation of the local cloud amount in top, mirror field can cause the wide fluctuations of steam output, may cause the cooling of superheating surface on the heat absorber not enough thus, thereby causes the overtemperature and the damage of pipe.
The present invention is according to the thermodynamic system result calculated; Design multi-tower type binary working medium solar heat power generation system; Comprised a fused salt heat absorber; Corresponding with it a plurality of water conservancy project matter heat absorbers are accomplished the preheating evaporation process of water (water vapor), the heating process of fused salt respectively, and are heated to water vapor the mistake thermal parameter that needs with the fused salt of high temperature.In this system; Make the superheating process of water vapor to accomplish into by the fused salt heating; And (one of them) adopts thermal capacitance height, the better fused salt of heat-conducting property as heat-carrying agent on solar heat absorber, and this fused salt system is made up of several parts such as pump for liquid salts, fused salt heat absorber, steam superheater (case side is that fused salt, pipe inboard are steam), fused salt jars.This system constitutes simple, but its specific aim has solved the problem that existing system exists; Because the coefficient of heat transfer of fused salt is high, the thermal capacitance characteristic is good; Therefore utilize fused salt as heat-carrying agent; Can take away the heat on the solar heat absorber fast, and the fused salt of high temperature can improve the energy conversion efficiency of system thus through the high-quality steam of steam superheater generation; Simultaneously, because this fused salt loop has relative independence, so the variation of steam output do not constitute direct influence to this loop, as long as the flow of control fused salt system is in zone of reasonableness, problems such as corresponding heat absorber overtemperature, damage just can not occur; In multi-tower type binary working medium solar heat power generation system; Fused salt only is used for the heating of superheated vapor; Therefore the operating temperature range of fused salt is not prone to the local solidification phenomenon of fused salt far above its solidifying point, and this is very useful for the Security of system.
The present invention combines the heat-carrying working medium (fused salt, conduction oil, liquid metal, organic working medium etc.) of working-medium water common in the firepower unit (water vapor) with the high heat capacity characteristic, has following remarkable advantage:
(1) to have kept to greatest extent with water (water vapor) be the advantage (as: technology maturity height, good reliability, control are simple etc.) of the solar heat power generation system of working medium in the present invention; The superheating process of steam has then adopted the fused salt of high heat capacity characteristic, high heat-transfer performance as heat-carrying agent; The system of this combined type makes the superheated vapor parameter be able to obvious raising, can improve the generating efficiency of system thus.
(2) a plurality of heat absorbers have adopted water (water vapor) to make heat-absorbing medium among the present invention; Because the liquid water and the water vapor of two phases have lower temperature; Therefore when choosing the material of heat absorber; The conventional material that can select for use performance to meet the demands, and no longer select high temperature resistant, expensive stainless steel material etc. for use, thus the fabricating cost that can practice thrift heat absorber greatly.Simultaneously lower heat absorber wall temperature has also reduced system's mirror field mean heat flux and the isoparametric requirement of maximum heat current density, and this also can reduce controlling cost of Jing Chang.
(3) the present invention has improved the Security of system.If on heat absorber, directly arrange the hot loop of crossing of steam, when then sky cloud amount changes, the steam producing amount of evaporating heating surface is changed, thereby the steam flow that causes flowing through hot loop is difficult to control, may cause the overtemperature damage of hot loop etc. thus.And in the solar heat power generation system of multi-tower type system binary working medium; Employing is the simple cycle of heat-carrying agent with the fused salt; This loop has relative independentability, and its Security does not receive the influence of preheating evaporating surface working condition, the Security that therefore can improve heat absorber greatly.
(4) be the solar collector of medium owing to having adopted a plurality of in the present invention with water (water vapor); It is the heat absorber of working medium that the tube wall temperature of such heat absorber is lower than with the fused salt; Therefore the radiation and the convection heat losses of heat absorber will decrease; Result of calculation indicates that the solar heat power generation system that this method designs has higher energy conversion efficiency;
(5) also to have adopted with the saturation water be the heat-stored device of medium in the present invention; When occurring in short-term cloud amount on high; Saturation water can be realized flash distillation through step-down, makes supporting electricity generating device be in the state of sliding parameter operation, and the fluctuation of load situation of steamer power generation system is greatly weakened; Make whole system operation more stable, this is very important beyond doubt for the unit that is incorporated into the power networks of high power capacity.

Embodiment
Multi-tower type binary working medium solar energy high temperature heat generating system of the present invention has comprised two kinds of working mediums of different nature, and a kind of is water (water vapor), and another kind is the medium with hot properties, like fused salt, liquid metal, conduction oil, other organic media etc.For making argumentation easy, in this patent, only discuss as the representative of high temperature heat-carrying agent with fused salt, the binary working medium solar heat power generation system that adopts other high temperature media is just discussed no longer one by one.
(is example as the high temperature heat-carrying agent with fused salt) as shown in Figure 1, the present invention mainly comprises: oxygen-eliminating device 1, feed water pump 2, a plurality of drum 3 parallel with one another, water conservancy project matter heat absorber 4, saturated thermal accumulator 5, steam three-way valve 6, steam superheater 7, auxiliary heater 8, steam turbine 9, generator 10, vapour condenser 11, condensate pump 12, fused salt jar 13, pump for liquid salts 14, fused salt bypass valve 15 and the fused salt heat absorber 16 of a plurality of connections parallel with one another.
Course of normal operation of the present invention is summarized as follows: the effect of oxygen-eliminating device 1 is to remove the dissolved oxygen in the condensate system through steam heating, and this helps to prevent the oxygen corrosion of pipeline and heating surface.Water after the deoxygenation gets into the drum 3 (a plurality of) of parallel connection mutually respectively behind feed water pump 2; After the heating through water conservancy project matter heat absorber 4 (having a plurality of), become saturated vapour; Saturated vapour after carbonated drink is separated is introduced into saturated thermal accumulator 5; Enter into steam superheater 7 through steam three-way valve 6 again, become superheated vapor by the fused salt heating therein, be introduced into steam turbine 9 actings then.Drive generator (10) and produce electric energy.The steam that comes out from saturated thermal accumulator 5 also is provided with a subsequent use loop: produce superheated vapor through steam three-way valve 6 to auxiliary heater 8 and get into steam turbine 9; This loop the start-up course that can accelerate steam turbine 9 is set; Can also under fused salt system failure state, auxiliary thermal source be provided, increase the reliability of system.In said system, the thermal source of oxygen-eliminating device 1 is from the drum 3 at water conservancy project matter heat absorber 4 tops.
Except that above-mentioned water (water vapor) system, multi-tower type binary working medium solar energy high temperature heat generating system has also comprised a simple fused salt loop.The flow process in this loop is: the fused salt that stores in the fused salt jar 13; After pump for liquid salts 14 boosts, enter into fused salt heat absorber 16, in heat absorber 16, heat up, the steam superheater 7 of flowing through again is the steam in the heat transferred pipe; Flow back at last in the fused salt jar 13, accomplish a cyclic process.
Steam is accomplished expansion acting process in steam turbine 9, and drives generator 10 actings; The steam of discharging from steam turbine 9 is cooled, condenses into water in vapour condenser 11; Through condensate pump 12 boost and preheating after get into oxygen-eliminating device 1; Accomplish the circulation of whole water (water vapor) system.
Said process is the flow process under the multi-tower type binary working medium solar energy high temperature heat generating system nominal operating condition; Be to deepen understanding to this system work process, following content respectively this system is started in the morning, stops transport at dusk and the variable working condition condition under working procedure carry out more detailed argumentation:
Must carry out preheating to the fused salt pipe-line system before the system start-up in morning, fused salt solidifies, plugging otherwise liquid fused salt is prone to cause when running into cold pipeline.The preheating of fused salt heat absorber 16 realizes that through dropping into a certain proportion of solar energy reflection mirror pipeline and valve then are to take the mode of resistance heating power to carry out preheating.Through behind the heating schedule that presets; Fused salt pipeline and parts reach the temperature of setting, open the circulation that pump for liquid salts 14 and fused salt bypass valve 15 are tentatively set up the fused salt system, treat that fused salt heat absorber 16 is preheating to setting temperature after; Charge fused salt heat absorber 16, and discharge gas wherein through bleed valve.After fused salt heat absorber 16 all is full of, close fused salt bypass valve 15 gradually, the fused salt system enters into normal working.The startup of water (water vapor) system is more simple: at first drop into auxiliary vapour source and give oxygen-eliminating device 1 deoxygenation of heating, open boiler feed pump 2 and inject drum 3 to the back of boosting of the water after the deoxygenation, in drum falling tube and water conservancy project matter heat absorber 4, be full of undersaturated water.Drop into more mirror system gradually; Feedwater working medium heat absorber 4 heats with fused salt heat absorber 16; Water in the water conservancy project matter heat absorber 4 is vaporized after absorbing heat gradually; In the outlet port of heat absorber 4 upper ends is the water that has certain steam quality, and steam constantly boosts in drum 3, and the saturated vapour after the separation is introduced into saturated thermal accumulator 5.Fused salt gets into steam superheater 7 after fused salt heat absorber 16 heats up, the steam that produces certain degree of superheat gets into steam turbine 9 actings.Multi-tower type binary working medium solar heat power generation system is duration of work by day, because intensity of solar radiation constantly conversion with the difference of solar incident angle, parameters such as the steam flow of system are also changing thereupon, and steam turbine is operated in a variable working condition state.
When vacating the cloud of existing short time the same day, the energy that system receives reduces thereupon, and the steam output of system also decreases; But because system has comprised saturated thermal accumulator 5; Its inside is the saturation water of certain liquid level, and along with the reduction of system pressure, the flashing effect of saturation water can produce compensatory saturated vapour; Therefore the decline of superheated vapor parameter just can not be too rapid, and steam turbine 9 can adapt to this variable working condition condition (sliding pressure operation that steam inlet condition reduces gradually); When otherwise the same day, aerial cloud shifted out the mirror field gradually, because the thermal storage effect of system, the output parameter of system also was the state that can be slow rising, made steam turbine 9 adapt to this variable working condition characteristic more easily.
At dusk or when overcast and rainy, when the energy of system's input can not be kept the normal operation of system, just must make system stop transport.Fused salt in the pipeline of fused salt system and each parts must be put back in the fused salt jar 13, to prevent condensing of fused salt.The horizontal pipeline of fused salt system all is designed to have the structure of certain slope; When stopping transport in system like this; Can utilize the gravity of fused salt to make fused salt from flowing back into fused salt jar 13; For fused salt heat absorber 16 and steam superheater 7, be provided with the fused salt escape cock in the least significant end of each parts, to make things convenient for the backflow of fused-salt medium.Water in drum 3 and the water conservancy project matter heat absorber 4 whether emptying depends on the heat dissipation characteristics of these parts: if thermal loss is big; Even icing danger arranged; Then necessary emptying drum 3 and water conservancy project matter heat absorber 4, otherwise need not the above-mentioned parts of emptying, when second day open system, just become more simple like this.
If the fused salt system breaks down, then auxiliary heater 8 can substitute the fused salt system and carries out work, and auxiliary heater can be heated to the degree of superheat that needs to saturated vapour, thereby ensures that whole solar heat power generation system normally moves.
In above-mentioned example system, according to the characteristics and the energy distribution relation of solar energy high temperature heat generating system, carry out ingenious the separation to the preheating evaporation process of water with the superheating process of saturated vapour, realize through different heat absorbers; Wherein the energy of steam superheating part is from fused salt system independently.Because the heat-carrying agent difference that dissimilar heat absorbers is inner: a kind of is water (water vapor), and another kind is high temperature heat-carrying agent (fused salt, liquid metal, an organic substance etc.); The operating temperature of the two differs greatly.Therefore can select material different and technology for use to different heat absorbers: the heat absorber that is used for feed-water preheating and evaporation can adopt the material that tolerable temperature is lower, price is relatively cheap (like carbon steel etc.); Heat absorber for the high temperature heat-carrying agent then adopts the higher alloy material of tolerable temperature (like stainless steel etc.).Concrete design proposal should be chosen according to the characteristic of thermodynamic system, the factor optimizations such as solar radiation characteristic of Jing Chang.
After adopting the solar energy heat absorbing system of multi-tower type binary working medium, owing to good heat-transfer, the thermal capacitance of fused salt are high, therefore the heating surface cooling of fused salt heat absorber fully just is difficult for taking place accidents such as overtemperature, booster; Volume and hot area that fused salt can dwindle heat absorber as heat-carrying agent, this has not only practiced thrift the manufactured materials of heat absorber, has also reduced the radiation loss on heat absorber surface; Can find out that from above-mentioned example fused salt has also increased the adaptability of system under the variable working condition condition as the high temperature heat-carrying agent; In addition, saturated thermal accumulator and auxiliary heater is provided with flexibility and the availability that has increased system.Can find out from above-mentioned argumentation: this multi-tower type binary working medium solar energy high temperature heat generating system has distinguishing features such as energy conversion efficiency height, Security are good, initial cost province, is an important directions of the hot generation technology of solar energy high temperature.
