Abstract
The utility model provides a molten salt heat accumulation device which comprises a primary molten salt can, a secondary molten salt can, a molten salt pump and a communicating pipeline, wherein the bottom of the primary molten salt can is communicated with the bottom of the secondary molten salt can through the communicating pipeline, and the molten salt pump is installed at the position of a discharge port of the secondary molten salt can. According to the molten salt heat accumulation device, molten salt is collectively stored by the primary molten salt can and the secondary molten salt can, the primary molten salt can is mainly used for storing, and the secondary molten can is mainly used for transporting. Therefore, storage volume of molten salt is increased, meanwhile, the core of the molten salt heat accumulation device aims to reduce the axial length of the molten salt pump, so that costs of overall molten salt heat accumulation device are greatly reduced, and popularization and application of high-volume molten salt heat accumulation device are propelled.
Description
Technical field
The utility model relates to a kind of heat-storing device, is specifically related to a kind of fused salt heat-storing device.
Background technology
At present, the fused salt heat-storing device that uses of solar energy heat-storage system adopts the corollary apparatus of vertical type heat storing tank and vertical pump for liquid salts substantially.Cooperating process with vertical pump for liquid salts in the vertical type heat storing tank is: in the vertical type heat storing tank, the salt of storage is heated to be the high-temperature liquid state saline admixture, when needs utilize fused salt heat energy, use the liquid saline admixture of vertical pump for liquid salts extracting high-temperature in the vertical type heat storing tank, then make high-temperature liquid state saline admixture and other media carry out heat exchange and use fused salt heat energy.
For increasing the quantity of heat storage of fused salt heat-storing device, jumbo vertical type heat storing tank has appearred in prior art, and it is highly over 10 meters; Accordingly, require the axial length of matching used vertical pump for liquid salts also greater than 10 meters.But the long vertical pump for liquid salts of length exists manufacturing process complexity and the high shortcoming of cost, thereby has limited applying of large capacity fused salt heat-storing device.
The utility model content
For the defective that prior art exists, the utility model provides a kind of fused salt heat-storing device, have advantages of simple in structure, cost is low.
The technical solution adopted in the utility model is as follows:
The utility model provides a kind of fused salt heat-storing device, comprises main fused salt tank, secondary fused salt tank, pump for liquid salts and connecting pipe; The bottom of described main fused salt tank is communicated with by described connecting pipe with the bottom of described secondary fused salt tank, and described pump for liquid salts is arranged on the discharging opening place of described secondary fused salt tank.
Preferably, the volume of described secondary fused salt tank is less than the volume of described main fused salt tank.
Preferably, the height of described secondary fused salt tank is less than the height of described main fused salt tank.
Preferably, described connecting pipe is provided with valve.
Preferably, described connecting pipe is horizontally disposed with.
The beneficial effects of the utility model are as follows:
The fused salt heat-storing device that the utility model provides, jointly store fused salt by main fused salt tank and secondary fused salt tank, the Main Function of main fused salt tank is to store, the Main Function of secondary storage salt cellar is to carry, therefore, when increasing the fused salt memory space, its core is the axial length that has reduced pump for liquid salts, thereby greatly reduce the cost of whole fused salt heat-storing device, promoted applying of large capacity fused salt heat-storing device.
Description of drawings
The structural representation of the fused salt heat-storing device that Fig. 1 provides for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
As shown in Figure 1, the utility model provides a kind of fused salt heat-storing device, comprises main fused salt tank 1, secondary fused salt tank 2, pump for liquid salts 4 and connecting pipe 3; The bottom of described main fused salt tank is communicated with by described connecting pipe with the bottom of described secondary fused salt tank, and described pump for liquid salts is arranged on the discharging opening place of described secondary fused salt tank.Because the fused salt heat-storing device that the utility model provides is stored fused salt jointly by main fused salt tank and secondary fused salt tank, therefore, when increasing the fused salt memory space, reduced the height of single fused salt tank, reduced accordingly the axial length of pump for liquid salts.
In actual applications, the height of secondary fused salt tank is less than the height of main fused salt tank.Therefore pump for liquid salts is arranged on the discharging opening place of secondary fused salt tank, makes pump for liquid salts extract the fused salt of storing in secondary fused salt tank, can reduce the axial length of pump for liquid salts; In addition, because the bottom of main fused salt tank is communicated with by connecting pipe with the bottom of secondary fused salt tank, therefore, in the process of the high-temperature liquid state fused salt in pump for liquid salts extracts secondary fused salt tank, the secondary fused salt tank of high-temperature liquid state fused salt meeting automatic stream in main fused salt tank, thereby keep main fused salt tank consistent with the liquid level of secondary fused salt tank, therefore, major-minor fused salt tank only need arrange pump for liquid salts at secondary fused salt tank place and get final product.Connecting pipe is provided with valve 5, thereby controls mobile start and stop and the flowing velocity of the high-temperature liquid state fused salt between main fused salt tank and secondary fused salt tank.In addition, connecting pipe is horizontally disposed with the traffic flow of controlling the high-temperature liquid state fused salt between main fused salt tank and secondary fused salt tank by valve.
In sum, the fused salt heat-storing device that the utility model provides, jointly store fused salt by main fused salt tank and secondary fused salt tank, the Main Function of main fused salt tank is to store, and the Main Function of secondary storage salt cellar is to carry, therefore, when increasing the fused salt memory space, its core is the axial length that has reduced pump for liquid salts, thereby greatly reduces the cost of whole fused salt heat-storing device, has promoted applying of large capacity fused salt heat-storing device.
The above is only preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be looked protection domain of the present utility model.
