The molten salt melting latent heat and sensible heat combination heat accumulator is simple in structure, problems existing in the prior art are solved, and large-scale heat accumulation can be realized in a stacking way.
Description
Technical field
The utility model relates to a kind of solar energy thermal-power-generating and combines heat storage with fused salt thawing latent heat with sensible heat.
Background technology
Usually carry out heat accumulation with the fused salt sensible heat in existing tower type solar energy thermal power generation and the butterfly solar engineering, realize the process of heat accumulation and heat release by the up-down of temperature of molten salt, during fused salt do not undergo phase transition.The quantity of heat storage of this heat accumulation mode unit volume is little, the heat accumulation complex equipments, and the heat accumulation cost is high.
The utility model content
To the problem that prior art exists, the purpose of the utility model is to provide the fused salt thawing latent heat that a kind of heat accumulation device structure is simple, cost is low, the unit volume quantity of heat storage is big to combine heat storage with sensible heat.
For realizing above-mentioned purpose; The utility model fused salt melts latent heat and combines heat storage with sensible heat; Comprise the ceramic honey comb housing, space is provided with several vertical-type cavitys in it, is filled with the phase transformation fused salt in this cavity; And, be provided with on the spaced walls between the sidewall of ceramic honey comb housing and several cavitys and be used for several through holes that recuperated gas passes through.
Further, several said through holes vertically laterally arrange, its whole honeycomb pass structure that forms.
Further, the upper end of said cavity is provided with opening, and this opening part is provided with cap.
Further, the loading of said phase transformation fused salt is 60%～80% of a said cavity volume.
Further, the said phase transformation fused salt mixture that is chlorate.
The utility model fused salt melts latent heat and combines heat storage body structure simple with sensible heat, has solved the problem that exists in the prior art, can adopt the mode of accumulation to realize extensive heat accumulation.
Description of drawings
Fig. 1 is the utility model vertical view;
Fig. 2 be among Fig. 1 A-A to cutaway view;
Fig. 3 be among Fig. 1 B-B to cutaway view.
The specific embodiment
Below, with reference to accompanying drawing, the utility model is more comprehensively explained, the exemplary embodiment of the utility model has been shown in the accompanying drawing.Yet the utility model can be presented as multiple multi-form, and should not be construed as the exemplary embodiment that is confined to narrate here.But, these embodiment are provided, thereby make the utility model, and the scope of the utility model is fully conveyed to those of ordinary skill in the art comprehensively with complete.
In order to be easy to explanation, here can use such as " on ", D score " left side " space relative terms such as " right sides ", be used for element shown in the key diagram or characteristic relation with respect to another element or characteristic.It should be understood that except the orientation shown in the figure spatial terminology is intended to comprise the different azimuth of device in using or operating.For example, if the device among the figure is squeezed, be stated as the element that is positioned at other elements or characteristic D score will be positioned at other elements or characteristic " on ".Therefore, the exemplary term D score can comprise upper and lower orientation both.Device can otherwise be located (revolve turn 90 degrees or be positioned at other orientation), and the relative explanation in used here space can correspondingly be explained.
Like Fig. 1, Fig. 2, shown in Figure 3; The utility model fused salt melts latent heat and combines heat storage with sensible heat; Comprise phase transformation fused salt 1, ceramic honey comb housing 2 and cap 3, the space is provided with several vertical-type cavitys 4 in the ceramic honey comb housing 2, is filled with phase transformation fused salt 1 in the cavity 4; And, be provided with on the spaced walls between the sidewall of ceramic honey comb housing 2 and several cavitys 4 and be used for several through holes 5 that recuperated gas passes through.
Several through holes 5 vertically laterally arrange, and evenly gather on ceramic honey comb housing 2 its whole honeycomb pass structure that forms.The upper end of cavity 4 is provided with opening, and this opening part is provided with cap 3.The loading of phase transformation fused salt 1 is 60%～80% of cavity 4 volumes.
The utility model fused salt melts latent heat and combines the heat storage production process to be with sensible heat: ceramic honey comb housing 2 is fired in processing earlier, in the cavity 4 of housing, fills phase transformation fused salt 1 pressed powder again, and loading is 80% of cavity 4 volumes, and then adds cap 3 encapsulation.Disposing way in use is that cap 3 is towards the top.
The heat transfer medium that the utility model heat storage uses is gas; High-temperature gas flows through from the through hole 5 of ceramic honey comb housing 2 when heat accumulation; Heat is passed to ceramic honey comb housing 2; Ceramic honey comb housing 2 is passed to the inner phase transformation fused salt 1 of heat storage with the part heat again, and phase transformation fused salt 1 begins to melt when the temperature of phase transformation fused salt 1 is elevated to its fusing point, realizes melting the heat accumulation process that latent heat combines with sensible heat.Cryogenic gas flows through from the through hole 5 of ceramic honey comb housing 2 when heat release; Absorb the heat in the ceramic honey comb housing 2; The heat of the phase transformation fused salt 1 that ceramic honey comb housing 2 can be inner with heat storage simultaneously conducts to gas; When the temperature of phase transformation fused salt 1 was reduced to its fusing point, phase transformation fused salt 1 began to condense, and realized melting the exothermic process that latent heat combines with sensible heat.
Phase transformation fused salt 1 adopts the mixture of chlorate, and its fusing point is fit to the heat accumulation temperature requirement in existing tower type solar energy thermal power generation and the butterfly solar engineering at 463 ℃.Fused salt melts latent heat and combines heat storage can adopt the mode of accumulation to realize extensive heat accumulation with sensible heat.
