Accompanying drawing explanation
The structural representation of Fig. 1 to be the present invention with gas be sensible heat-latent heat compound thermal storage device of heat-transfer fluid.
Detailed description of the invention
As shown in Figure 1, the present invention take gas as the sensible heat-latent heat compound thermal storage device of heat-transfer fluid, and for solar energy thermal-power-generating field, high temperature air is heat-transfer fluid, also can be used for cogeneration field, and industrial high temperature waste heat stores.Described is that the sensible heat-latent heat compound thermal storage device of heat-transfer fluid comprises heat storage can with gas, leaves charging process high-temperature gas and flows into pipe 8, leave exothermic process cryogenic gas inflow pipe 7 in the bottom of heat storage can on the top of heat storage can.
Spherical sensible heat-latent heat compound heat accumulation ball 3, refractory concrete ball 1 and sensible heat-latent heat compound heat accumulation double-edged fine-toothed comb 2 is provided with in heat storage can inside, spherical sensible heat-latent heat compound heat accumulation ball 3 is arranged on the inner upper strata of heat storage can, refractory concrete ball 2 and abnormity concrete block are arranged on the inner middle level, upper strata of heat storage can, and sensible heat-latent heat compound heat accumulation double-edged fine-toothed comb 1 is arranged on the inner lower floor of heat storage can.Described refractory concrete ball 1 also can be replaced abnormity concrete block.
Described sensible heat-latent heat compound heat accumulation double-edged fine-toothed comb 1 is by being filled with phase-change material metal bar in length and breadth to being welded.Described phase-change material is fuse salt or metal alloy, by metal bar during making, be preferably in stainless steel tube and carry out two ends shutoff after perfusion fuse salt or metal alloy, form the heat accumulation element carrying out compound heat accumulation with the phase-change thermal storage of steel pipe sensible heat and Qi Nei fuse salt or metal alloy.Multiple heat accumulation element is connected to form gridding framework by welding manner, replaces the metal double-edged fine-toothed comb of the stacking bed heat storage can bottom of existing Ceramic Balls, both realizes heat storage function, realize again mechanics function.This sensible heat-latent heat compound heat accumulation double-edged fine-toothed comb can singlely also can multiple pile rise, to increase heat accumulation effect.
