Problems solved by technology
[0004] Existing heat storage devices are divided into double-tank heat storage devices and single-tank heat storage devices. The cost of double-tank heat storage devices is high, and the heat storage capacity per unit volume is small, while the distribution of the thermoclinic layer of single-tank heat storage devices is not obvious

Embodiment Construction
[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0024] see figure 1 with figure 2 , the high-low temperature molten salt single-tank heat storage device provided by the present invention includes a hollow tank body 100 , a first partition 200 and a second partition 300 .
[0025] Tank body 100, which is a sealed vertical structure, is equipped with a high-temperature molten salt entry and exit mechanism on its top, and a low-temperature molten salt entry and exit mechanism is provided at the bottom of the tank body 100. The top enters and exits, and the low-temperature molten salt can enter and exit at the bottom of the tank body 100 through the low-temperature molten salt entry and exit mechanism.
[0026] The high-temperature molten salt inlet and outlet mechanism includes a high-tempera...

The invention discloses a high-low-temperature molten salt single-tank heat storage device. The high-low-temperature molten salt single-tank heat storage device comprises a hollow tank, a first partition board and a second partition board. A high-temperature molten salt inlet / outlet mechanism is arranged at the top of the tank, and a low-temperature molten salt inlet / outlet mechanism is arranged at the bottom of the tank. The first partition board is movably arranged in the tank and provided with a plurality of first through holes. The second partition board is movably arranged in the tank andlocated under the first partition board. A thermocline layer is arranged between the second partition board and the first partition board. The second partition board is provided with a plurality of second through holes. The second through holes, the thermocline layer and the first through holes communicate in sequence. The high-low-temperature molten salt single-tank heat storage device is of a single-tank structure, greatly saves the cost, can maintain the stability in the heat accumulation and heat release process and reduces heat loss caused by low-temperature molten salt heat exchange.
Description
technical field [0001] The invention relates to the technical field of photothermal power generation heat storage, in particular to a high-low temperature molten salt single-tank heat storage device. Background technique [0002] In the utilization of new energy, solar thermal power generation, usually called concentrated solar power generation, is one of the most promising forms of new energy. It obtains heat energy by gathering solar radiation, converts the heat energy into high-temperature steam, and the steam drives a steam turbine to generate electricity. According to the form of heat collection, it can be divided into trough power generation, tower power generation and dish power generation. At present, the number of trough power plants is the largest, and it is a type with relatively mature technology and cost in the world. The number accounts for about 80% of the total number of operations and construction. Tower power plants account for more than 11%, and dish powe...
