As shown in fig. 1, a movable plate 50 is vertically arranged in the molten salt single tank 10, and two ends of the movable plate 50 are connected with the molten salt single tank 10 in a sliding and sealing manner; the fused salt single tanks 10 on the two sides of the movable plate 50 are communicated through a pipeline 1; divide into two spaces with fused salt single tank 10 through fly leaf 50, it is specific, fly leaf 50 has divided into the regional 11 of hot jar and the regional 12 of cold jar with fused salt single tank 10, wherein sets up electric heating assembly 20 in the regional 11 of hot jar, is equipped with pipeline 1 between the regional 11 of hot jar and the cold jar region 12, is equipped with fused salt pump 2 on the pipeline 1, satisfies the fused salt conversion between the regional 12 of cold jar and the regional 11 of hot jar through fused salt pump 2.

The heat exchanger 30 is arranged at one side of the single molten salt tank 10, in particular, in order to realize the flow of the molten salt by utilizing the self weight of the molten salt, therefore, as shown in fig. 1, the heat exchanger 30 is arranged below the single molten salt tank 10, the bottom of the hot tank area 11 is communicated with the heat exchanger 30 through a pipeline 1, and the bottom of the heat exchanger 30 is communicated with the cold tank area 12; a circulation is formed by the hot tank area 11, the heat exchanger 30 and the cold tank area 12, wherein the molten salt in the cold tank area 12 is conveyed to the hot tank area 11 through the molten salt pump 2; the heat exchanger 30 is connected with a medium pipe 40; the medium pipe 40 is used for conveying a medium to exchange heat with the molten salt.

Further, in some embodiments, the heat exchanger 30 includes a housing 31, a stationary assembly 32, and a movable assembly;

as shown in fig. 2-3, the housing 31 is a plurality of cylindrical thin walls arranged concentrically; the annular spaces are mainly used for providing the flow of molten salt and a medium, so that the heat transfer between the molten salt and the medium is facilitated; specifically, in the present embodiment, 4 concentric circles are provided.

The fixed components 32 are a plurality of barrier plates which are circumferentially distributed by taking the circle center of the shell 31 as an axis, the number of the barrier plates is 3, and the thin wall is divided into a plurality of spaces by the barrier plates; each space is communicated with the heat pipe area and the medium pipe 40 in a staggered mode; the inner part of the shell 31 is divided into 9 spaces by matching 4 layers of thin walls and 3 baffle plates, molten salt and a medium are distributed in the 9 spaces in a staggered mode, the distance between the concentrically arranged cylindrical thin walls is small, therefore, the contact area between the thin walls serves as a main heat conduction surface of the molten salt and the medium, and the size of the main heat conduction surface occupies more than half of the area of each space.

As shown in fig. 5 and 6, the movable assembly includes an end cap 330 and 3 movable members 33, the movable members 33 are fixedly connected to the end cap 330, the movable members 33 are respectively disposed in the spaces formed by the blocking plate and the thin wall, and the end cap 330 is connected to the housing 31 in a rotary sealing manner; the movable members 33 are a plurality of baffle plates, and the baffle plates are connected with the thin wall in a sliding and sealing manner; the original 9 spaces are changed into 18 spaces by arranging baffles, and a sector area of the spaces is taken as an example, and the first space 101, the second space 102, the third space 103 and the fourth space 104 are arranged in sequence from outside to inside; if molten salt flows in the first space 101, medium flows in the second space 102, and the like are staggered; it should be noted that, due to the rotation of the baffle, the original areas of the first space 101, the second space 102, the third space 103 and the fourth space 104 will change, and here, in detail, if the first space 101 is filled with molten salt, the second space 102 is filled with medium, and the third space 103 is filled with molten salt, the first to third spaces 104 of the partition wall of the baffle inside the two fixed baffle plates are the medium layer, the molten salt layer and the medium layer in sequence, where, when the baffle moves from the rightmost end to the leftmost end, the area of the first space 101 filled with the molten salt layer on the left side of the baffle will become larger, the area of the first space 101 filled with medium on the right side of the baffle will become smaller, the shell 31 is analogized from the outside to the inside, and due to the radian, the area change value of the first space 101 is larger than the area change value of the second space 102 and is larger than the area change value of the third space 103 and is larger than the area change value of the fourth space 104, because the molten salt layer and the medium layer are arranged in 18 spaces in a staggered mode, the ratio of the throughput of the molten salt to the throughput of the medium in the whole heat exchanger 30 is changed along with the movement of the baffle, and if the movement angle of the baffle is 30-45 degrees according to simulation calculation. Then the ratio change can be from 0.8: 1..2 to 1.2: 0.8; by varying this ratio, the purpose of dynamic adjustment is achieved, such as: when high temperature molten salt is used for the first time, the temperature of the molten salt is 500 ℃, then 0.8: 1.2, when the molten salt temperature is reduced from 500 ℃ to 300 ℃ along with the recycling of the hot lava, if a medium with a stable target temperature is to be obtained, 1.2: a ratio of molten salt to medium of 0.8 gives the medium we want the target temperature; illustratively, the transfer of temperature includes thermal conduction, thermal radiation, and thermal convection, and when the transfer temperature is too high, the efficiency is guaranteed, and when the transfer temperature is not so high, it is necessary to increase the thermal conduction efficiency, and then increasing the ratio is one of the means.
