Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below the utility model embodiment is described in further detail.
A kind of slot type heat reservoir, see Fig. 1, comprising: groove type heat collector 1, pump for liquid salts 2, fused salt conveyance conduit 3 and fused salt storage tank 4.Wherein, be provided with support 11, speculum 12 and thermal-collecting tube 13 in groove type heat collector 1, speculum 12 is arranged on support 11, and support 11 is arranged in torque tube (not shown), and thermal-collecting tube 13 is arranged on reflection groove focal line.
Support 11 is by fluid pressure drive device driving torque pipe, torque tube drives support 11 to rotate, speculum 12 also together follows rotation, follow the tracks of sunshine, make solar light focusing in the thermal-collecting tube 13 being arranged in reflection groove focal line, Molten Binary Salts (60%NaNO3+40%KNO3) in heating thermal-collecting tube 13, makes its temperature rise and reaches 550 DEG C, enter fused salt storage tank 4 by fused salt conveyance conduit 3.
During specific implementation, when solar irradiation condition is good, can be heated by this slot type heat reservoir to fused salt, partial heat is used for heat exchange and produces steam drive steam turbine power generation, and partial heat is stored in fused salt storage tank 4; When night or illumination condition difference time, the fused salt being stored in fused salt storage tank 4 is used to carry out heat exchange with water, produces steam and drives steam turbine power generation.
Wherein, fused salt through heating is stored in fused salt storage tank 4, remain on 550 DEG C by the temperature in electric heater unit maintaining heat fused salt tank 4, when sunshine is not enough, uses the fused salt that is stored in hot melt salt cellar 4 and water to carry out heat exchange and produce steam and drive steam turbine power generation or for heating.
Because fused salt price is low, corrosivity is little, heat endurance and good thermal conduction, serviceability temperature scope be wide, therefore use fused salt as heat-storage medium, effectively the thermal energy storage that solar energy is changed can be got up, realize the continuity of photo-thermal power generation, improve the utilization ratio of solar energy.And by using fused salt as transmission medium, improve the security of transmitting procedure, avoiding potential safety hazard.
During specific implementation, speculum 12 can be plane mirror.
During specific implementation, electric heater unit is specially resistance type heater.
The utility model embodiment is to the model of each device except doing specified otherwise, and the model of other devices does not limit, as long as can complete the device of above-mentioned functions.
It will be appreciated by those skilled in the art that accompanying drawing is the schematic diagram of a preferred embodiment, above-mentioned the utility model embodiment sequence number, just to describing, does not represent the quality of embodiment.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
