Description
Technical field
The present invention relates to the heat accumulating module, particularly relate to a kind of preparation method of prefabricated concrete heat storage module for solar heat power generation.
Background technology
The heat accumulating that is used for solar electrical energy generation should satisfy following requirement: heat accumulating should have high energy density; Heat accumulating and heat exchanger fluid should have good heat conduction; Heat accumulating should have good chemistry and mechanical stability; Good chemical compatibility is arranged between heat accumulating and heat exchanger and the heat exchanger fluid; In heat accumulation and heat release cyclic process, answer completely reversibility; Low-cost.The heat accumulation conceptual design is the important technology in the solar steam generating, and the performance of heat accumulating and cost are one of the construction cost of decision large-sized solar power plant and principal element of operating cost.The mode of heat accumulation mainly contains the sensible heat heat accumulation, phase-change thermal storage and chemical reaction heat storage at present.And the most ripe and heat accumulation mode that have a commericially feasible is the sensible heat heat accumulation in present technology.The sensible heat heat accumulation is divided into liquid sensible heat and solid sensible heat again.
Mainly contain fused salt (KNO as the liquid heat accumulating in the solar steam generating at present
3, NaNO
3Or both mixtures).Document 1 (Kakiuchi; Hiroyuki; Oka; Masahiro, US patent (No.5567346)) reported Japanese scholar's United States Patent (USP), wherein with sodium sulphate, ammonium chloride, sodium bromide and ammonium sulfate are the heat accumulating that primary raw material is formed.Document 2 (Ross; Randy, US patent (No.5685151)) patent has reported then and has been used for the solar energy heat-storage material that major ingredients is a sodium chloride.But fused salt exist one very obvious defects be its stronger corrosivity, heat exchanging pipe and other affiliated facility are had very strong corrosion behavior, increased the operating cost of power plant thus, also reduced the security of system stability.The solid heat accumulating is one of ideal candidates heat accumulating that is used for the solar steam generating owing to have plurality of advantages such as stable performance, cost is low, heat storage capacity is strong.Document 3 (Xiao Lichuan, the application of concrete storage heater in solar power station, Jiangsu Chemical Engineering College's journal, 1991,3 (1): 17-23) reported, proved the feasibility of concrete heat accumulating in solar power station by theoretical calculating.Document 4 (Doerte Laing, Wolf-Dieter Steinmann, Rainer Tamme, Christoph Richter.Solidmedia thermal storage for parabolic trough power plants, Solar Energy, 2006,80 (10): 1283-1289) with document 5 (Rainer Tamme, Doerte Laing, Wolf-Deter Steinmann, Advanced thermal energy storagetechnology for parabolic trough, Journal of solar energy engineering, 2004,126:794-800) on research sand-stone concrete and the concrete basis of basalt, solid heat accumulatings such as research and development heat resistance concrete and castable ceramic, the aggregate of refractory concrete mainly is an iron oxide, cement is adhesive; The castable ceramic aggregate mainly is an iron oxide also, and adhesive comprises aluminium oxide etc.Document 6 (Ulf herrmann, David Wearney.Survey of thermal energy storage forparabolic trough power plants[J], Journal of solar energy engineering, 2002,124:145-152) compared the cost of electricity-generating of several heat accumulatings, thought that the cost of concrete material also is minimum.
In fact, the solar energy thermal-power-generating heat accumulating not only needs the excellent comprehensive performance, and need low cost, cost of transportation and cost of manufacture are also very important under a lot of situations, the raw material that Deutschen Zentrums fur Luft-und Raumfahrt e.V. in the document 4 (DLR) is adopted is aluminium oxide and iron oxide, its raw material relative price is than higher, and be to adopt the cast-in-site mode, small-scale be feasible in experiment link, but in the future during suitability for industrialized production, it is long often to be chosen in the sunshine sunshine-duration, the desert area that radiation intensity is big, therefore under many circumstances, want to adopt the situation of cast-in-site unrealistic, be not only the desert area lack of water, and do not have traffic electric power auxiliary facility, maintenance cost thereafter also is very huge.
