Description

Technical Field

[0001] The embodiments of the present application relate to the field of environmental protection and energy-saving technology, and in particular to a solid energy storage body structure, a stacking method, and a solid energy storage device. Background Art

[0002] In recent years, with the rapid development of wind power and photovoltaic clean energy in my country, solid electric thermal storage devices have been widely used in heating and industrial production heat. They can balance the power grid and achieve the effect of "peak shaving and valley filling" of the power grid. Reasonable use can improve the utilization rate of clean energy, reduce the emission of harmful gases such as carbon dioxide, sulfur dioxide, and dust, and reduce environmental pollution. In the prior art, since the temperature of the solid energy storage structure frequently rises and falls during the heat storage and heat release process, and the high and low temperature difference is particularly large, the energy storage body may creep due to thermal expansion and cold contraction during the temperature alternation between hot and cold. The creep can accumulate after a long period of hot and cold alternation cycles and produce large thermal displacement, which may cause the energy storage body to tilt and collapse in severe cases. This will cause irreversible safety accidents and equipment damage. Summary of the invention

[0008] In a feasible implementation, it also includes: The mounting side hole and the pancake-shaped heat-conducting half hole are arranged in the same plane of the energy storage body. The mounting side hole is symmetrically arranged along the two sides of the energy storage body and is in the same plane as the pancake-shaped heat-conducting half hole.

[0009] In a feasible implementation manner, the positioning blocks include a first positioning block group and a second positioning block group; The first positioning block group is arranged on one side of the energy storage body where the pancake-shaped heat-conducting half hole is opened; The second positioning block is arranged on the opposite side of the energy storage body where the pancake-shaped heat-conducting half hole is opened.

[0010] In a feasible implementation manner, the protrusion and the groove of the positioning block have a draft angle; The projection and the groove of the positioning block are chamfered.

[0011] In a feasible implementation manner, when the energy storage bodies are stacked, expansion gaps are left between the matching positioning blocks.

[0012] In a feasible implementation manner, when the upper and lower adjacent energy storage body bodies are not staggered, the first positioning block groups of the two energy storage body bodies conflict with each other, and when the upper and lower adjacent energy storage body bodies are staggered, the first positioning block groups of the two energy storage body bodies match each other.

[0013] In a feasible implementation manner, the energy storage body can be split into four half bricks along the radial direction and the axial direction of the pancake-shaped heat-conducting half hole; Alternatively, the energy storage body is divided into four quarter bricks along the axial and radial directions of the pancake-shaped heat-conducting half hole, and the quarter bricks located at opposite corners have the same structure.

[0014] In a feasible implementation manner, the solid energy storage body structure further includes: The raised strip is arc-shaped and is arranged on the bottom surface of the pancake-shaped heat-conducting half hole.

[0015] According to a second aspect of the embodiment of the present application, a stacking method is provided, which is applied to any of the above-mentioned solid energy storage body structures, comprising: stacking the surfaces of the solid energy storage body structures with pancake-shaped heat-conducting half holes relative to each other; The solid energy storage body structures are stacked to form a solid energy storage device; The bottom layer of the solid energy storage device is defined as the first layer, the opening ends of the pancake-shaped heat-conducting half holes of the solid energy storage body structure of the odd-numbered layers face upward, and the opening ends of the pancake-shaped heat-conducting half holes of the solid energy storage body structure of the even-numbered layers face downward; When stacked, the adjacent solid energy storage structures in the Z-axis direction are mutually limited by positioning blocks; When stacked, the solid energy storage body structures are arranged in a staggered manner; The solid energy storage device can be split into a solid energy storage body structure whole brick, a solid energy storage body structure half brick and a solid energy storage body structure quarter brick; When the solid energy storage device is stacked to the edge, a half-brick solid energy storage body structure and a quarter-brick solid energy storage body structure can be used according to usage requirements.

In the present technical solution, a pancake-shaped heat-conducting half hole is provided to reserve space for installing a resistance wire, while increasing the energy storage capacity.

It is suitable for solid energy storage body structures working under high-temperature and low-temperature alternating cycles. The thermal expansion of the solid energy storage body structure can be offset by the setting of the expansion gap, and the matching positioning blocks can be avoided from conflicting with each other when the solid energy storage body structure undergoes thermal expansion. This setting can further improve the stability of the solid energy storage body structure during stacking and avoid the risk of collapse. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0021] like Figure 1-Figure 5 As shown, according to the first aspect of the embodiment of the present application, a solid energy storage body structure 100 is proposed, including: an energy storage body body 110; a pancake-shaped heat-conducting half hole 120, wherein the pancake-shaped heat-conducting half hole 120 is formed on the energy storage body body 110, and the pancake-shaped heat-conducting half hole 120 is used to set a resistance wire. When two energy storage body bodies 110 are arranged opposite to each other, the two pancake-shaped heat-conducting half holes 120 are enclosed to form a pancake-shaped heat-conducting through hole; wherein, the bottom surface of the pancake-shaped heat-conducting half hole 120 is a plane, and the two side edges of the pancake-shaped heat-conducting half hole are hypotenuses, which are arranged on both sides of the bottom edge, and the bottom surface and the hypotenuse of the pancake-shaped heat-conducting half hole 120 are connected by an arc edge; a positioning block 130, wherein the positioning block 130 is arranged on the energy storage body body 110, and the positioning block 130 has a protrusion and a groove, and the positioning block 130 is used to position the stacked energy storage body bodies 110.

[0022] The solid energy storage body structure 100 provided in the embodiment of the present application includes an energy storage body body 110, wherein the energy storage body body 110 is a square structure, and a pancake-shaped heat-conducting half hole 120 is opened on the energy storage body body 110, and the pancake-shaped heat-conducting half hole 120 is used to set the resistance wire, and the pancake-shaped heat-conducting half hole 120 is a U-shaped slot. When two energy storage body bodies 110 are arranged relative to each other, the pancake-shaped heat-conducting half hole 120 is merged into a pancake-shaped heat-conducting through hole, and the resistance wire is arranged in the pancake-shaped heat-conducting through hole. It can be understood that when the space reserved for the pancake-shaped heat-conducting half hole 120 is sufficient, the resistance wire can be only arranged in the pancake-shaped heat-conducting half hole 120, and at the same time, the pancake-shaped heat-conducting half hole 120 can also play a role in ventilation and heat dissipation when the energy storage body 110 releases a large amount of heat. A positioning block 130 is provided on the energy storage body 110. When the energy storage body 110 is stacked, the positioning block 130 is used to limit the adjacent energy storage body 110 on the Y axis. In actual use, several energy storage body bodies 110 are usually stacked into an energy storage pile and connected for use. In use, it is often encountered that the energy storage body may produce creeping due to thermal expansion and cold contraction during the temperature alternation between hot and cold. The creeping may produce large thermal displacement after long-term accumulation of hot and cold alternation cycles, which may cause the energy storage body to tilt and collapse in severe cases. In the present technical solution, by setting up the pancake-shaped heat-conducting half hole 120, space is reserved for installing the resistance wire, and there is no need to provide an additional support structure for the resistance wire. At the same time, the heat dissipation effect of the energy storage stack is increased. By setting up the positioning block 130, the displacement limit between the energy storage blocks is increased, which can effectively avoid the cumulative thermal displacement of the energy storage body during the alternating hot and cold process, can significantly improve the structural strength and service life of the solid energy storage body structure 100, and can reduce the difficulty of construction. It is suitable for the solid energy storage body structure 100 working under high temperature and low temperature alternating cycles.

[0023] Among them, the bottom surface of the pancake-shaped heat-conducting half hole 120 is a plane, and the two side edges of the pancake-shaped heat-conducting half hole are beveled edges, which are arranged on both sides of the bottom edge, and the bottom surface and the beveled edges of the pancake-shaped heat-conducting half hole 120 are connected by arc edges; in this technical solution, the pancake-shaped heat-conducting through hole composed of two pancake-shaped heat-conducting half holes 120 has a pancake-shaped cross-section, which is similar to the cross-sectional shape of red blood cells. Red blood cells need to circulate in blood vessels throughout the body to provide oxygen to various tissues and organs throughout the body and transport away the generated carbon dioxide. Red blood cells are round pancake-shaped under a scanning electron microscope. This shape gives it a larger surface area and a larger surface area to volume ratio, which is conducive to gas exchange.

[0024] During the heat storage and release process, the solid energy storage structure exchanges heat with the electric heating element, and must ensure a sufficiently large specific surface area to effectively absorb the heat from the electric heating element for energy storage. Similarly, during the heat release process, a sufficiently large specific surface area ensures effective heat exchange with the wind, thereby increasing the heat exchange area and heat exchange efficiency.

[0025] Therefore, the cross-sectional shape of the pancake-shaped thermal conductive through hole simulates the cross-sectional shape of the red blood cells, and the bionic design is used to effectively increase the heat exchange area of ​​the pancake-shaped thermal conductive through hole and improve the heat exchange efficiency.

[0026] It is understandable that the thickness of the energy storage body 110 should be controlled between 50-100 mm. When the thickness is less than 50 mm, the strength of the energy storage body 110 cannot be guaranteed and it is easy to be crushed or broken. When the thickness exceeds 100 mm, the heat cannot be released in time, affecting the efficiency.

[0027] It is understandable that from an application perspective, the larger the brick size of the energy storage body 110 is, the better. However, considering the handling weight and processability, the width of the energy storage body 110 should be set between 200mm-400mm, and the maximum weight should not exceed 30kg, preferably 20kg.

[0028] like Figure 1-Figure 5 As shown, the solid energy storage body structure also includes: an installation side hole 140, the installation side hole 140 and the pancake-shaped heat-conducting half hole 120 are arranged in the same plane of the energy storage body 110, and the installation side hole 140 is symmetrically arranged along the two sides of the energy storage body 110, and is in the same plane as the pancake-shaped heat-conducting half hole 120.

[0029] In this technical solution, the solid energy storage body structure 100 also includes an installation side hole 140, which is one quarter of the through hole formed after the solid energy storage body structure is stacked. The installation side hole 140 is arranged in parallel with the pancake-shaped heat-conducting half hole 120. The installation side hole 140 and the pancake-shaped heat-conducting half hole 120 are arranged on the same plane of the energy storage body body 110. The installation side hole 140 is symmetrically arranged along the edge line of the plane of the energy storage body body 110. This arrangement first increases the ventilation area when the solid energy storage body structure 100 is stacked. Secondly, when the energy storage body body 110 is staggered, one pancake-shaped heat-conducting half hole 120 can form a complete pancake-shaped heat-conducting through hole with two installation side holes 140, so that the stacking of the energy storage body body 110 is more flexible.

[0030] like Figure 1-Figure 5 As shown, the positioning block 130 includes a first positioning block group and a second positioning block group; the first positioning block group is arranged on one side of the energy storage body 110 where a pan-shaped heat-conducting half hole 120 is opened; the second positioning block is arranged on the opposite side of the energy storage body 110 where a pan-shaped heat-conducting half hole 120 is opened.

[0031] In this technical solution, the positioning block 130 includes a first positioning block group and a second positioning block group, wherein the first positioning block group is arranged on a side of the energy storage body 110 where a pan-shaped heat-conducting half hole 120 is opened, and the second positioning block group is arranged on the opposite side of the energy storage body 110 where a pan-shaped heat-conducting half hole 120 is opened. When two energy storage body bodies 110 with one side having a pan-shaped heat-conducting half hole 120 are stacked relative to each other, the two first positioning block groups can be fitted and limited to each other, and the specific fitting method can be horizontal rotation. One of the first positioning block groups can realize the staggered arrangement of protrusions and grooves with the unrotated first positioning block group. When the energy storage body 110 and the side of the energy storage body 110 with the pancake-shaped heat-conducting half hole 120 are stacked back to back, the two second positioning block groups can be fitted and limited to each other. The specific fitting method is the same as the first limiting block group. The energy storage body 110 with the positioning block 130 is used for masonry. The upper and lower adjacent energy storage body bodies 110 are buckled together, which can limit the horizontal displacement and torsion of each other in the horizontal direction.

[0032] The energy storage body 110 is connected as a whole by the positioning block 130, which can effectively avoid thermal displacement of the solid energy storage body structure 100, improve the overall strength, and effectively prevent the problem of thermal displacement when the temperature difference changes, thereby improving the reliability of the overall energy storage body and the energy storage effect.

[0033] In this embodiment, the positioning block 130 is square.

[0034] like Figure 1-Figure 5 As shown, the protrusion and the groove of the positioning block 130 have a draft angle; the protrusion and the groove of the positioning block 130 have a chamfer.

[0035] In this technical solution, the protrusion and the groove of the positioning block 130 have a draft angle; the protrusion and the groove of the positioning block 130 have a chamfer, which can facilitate the demoulding of the energy storage body 110, reduce the defective part rate in the production process, and improve production efficiency.

[0036] like Figure 1-Figure 5 As shown, when the energy storage body 110 is in a stacked state, an expansion gap 170 is left between the matching positioning blocks 130 .

[0037] In this technical solution, an expansion gap 170 is left between the matching positioning blocks 130, which can offset the thermal expansion of the solid energy storage body structure 100 and avoid the matching positioning blocks 130 from conflicting with each other when the solid energy storage body structure 100 undergoes thermal expansion. This setting can further improve the stability of the solid energy storage body structure 100 when it is stacked and avoid the risk of collapse.

[0038] This technical solution avoids thermal displacement caused by thermal expansion and contraction and solves the risk of furnace collapse through the design of the first positioning block group, the second positioning block group, the expansion gap 170 and the staggered arrangement, while enhancing the earthquake resistance and being able to achieve earthquake resistance of magnitude 7.

[0039] like Figure 10-11 As shown, the buckle-free heat storage brick type is used, and the size deviation cannot be controlled when each layer is stacked. When multiple layers are stacked, the cumulative error will be large, causing the heat storage body to tilt. For the solid energy storage body structure 100 with the "inline" first positioning block group and the second positioning block group, the cumulative error is limited due to the mutual restrictions of the brick size and the positioning block 130 size.

[0040] like Figure 12-14 As shown, the buckle-free heat storage brick type is adopted. There is no relative position constraint between the heat storage bodies in the same layer. The disordered arrangement will lead to the inconsistency of the heat storage body spacing. The small spacing will cause the heat storage body to be squeezed, deformed or damaged. The local spacing is too large, which will cause the area to leak when the heat storage body is exchanging heat, affecting the uniformity of heat exchange. However, this technical solution uses the positioning block 130 to limit the position, ensuring that the width of the expansion gap 170 is stable.

[0041] like Figure 1-Figure 5 As shown, when the upper and lower adjacent energy storage body bodies 110 are not staggered, the first positioning block groups 131 of the two energy storage body bodies 110 conflict with each other; when the upper and lower adjacent energy storage body bodies 110 are staggered, the first positioning block groups 131 of the two energy storage body bodies 110 fit together.

[0042] In this technical solution, the first positioning block group 131 is set so that the energy storage body 110 can be matched only when it is staggered in the correct splicing method. The proposed method can be that the arrangement logic of the protrusion and the groove is different, and the fit cannot be achieved no matter how it is rotated, or the shape of the protrusion and the groove is different. The present invention does not limit this. At the same time, the conflict method with different arrangement logic is selected in this embodiment. This setting allows the operator to fit only when the placement is correct during stacking. It cannot fit if the direction is incorrect, which can prevent incorrect construction. The beneficial effect of this method is to improve the construction efficiency by 50%. At the same time, it ensures that when the energy storage body 110 is stacked, it can only be stacked by staggered stacking, which further improves the stability of the stacking of the energy storage body, ensures the construction quality, and the verticality and horizontality at a certain height.

[0043] It is understandable that in order to ensure strength and workability, the height of the bump should be limited to between 2-8 mm.

[0044] like Figure 6-Figure 8As shown, the energy storage body 110 can be split into four half bricks 150 along the radial direction and axial direction of the pancake-shaped heat-conducting half hole 120; or, the energy storage body 110 can be split into four quarter bricks 160 along the radial direction and axial direction of the pancake-shaped heat-conducting half hole 120, and the quarter bricks 160 located at the diagonal positions have the same structure.

[0045] The energy storage body 110 can be split into two half bricks 150 along the direction of the pancake-shaped heat-conducting half hole 120, and can be split into two half bricks 150 perpendicular to the direction of the pancake-shaped heat-conducting half hole 120. When the energy storage body 110 is arranged in a staggered manner, there will always be a gap in the side surface of the energy storage body stack. In this technical solution, the energy storage body 110 can be split into half bricks 150 to fill the gaps around the energy storage body stack. In this embodiment, the positioning blocks 130 are not arranged symmetrically, so there are four specific half bricks that can be split.

[0046] like Figure 8 As shown, when the energy storage body 110 can be split into four half bricks 150, the energy storage body 110 is split into four quarter bricks 160 along and perpendicular to the pie-shaped heat conductive half hole 120, and the quarter bricks 160 located at opposite corners have the same structure.

[0047] In this technical solution, when the energy storage body 110 is arranged in a staggered manner, there will always be gaps in the four corners of the energy storage body stack. In this technical solution, the energy storage body 110 can be split into quarter bricks 160 to fill the gaps in the energy storage body stack. In this embodiment, the positioning block 130 is centrally symmetrical, so there are two specific types of quarter bricks 160 that can be split.

[0048] It can be understood that the arrangement of the half brick 150 and the quarter brick 160 allows the energy storage body 110 to be stacked in an offset manner, making the arrangement of the solid energy storage body structure 100 more flexible. When encountering an energy storage body that is not a whole block in the horizontal direction, the half brick 150 and the quarter brick 160 can be stacked together to form a complete energy storage body stack, thereby improving the stability of the stacked energy storage body stack.

[0049] It is understandable that the quarter brick 160 still has the positioning block 130 and can still effectively limit the position. The positioning block 130 on any joint surface of the quarter brick 160 has at least three protrusions, thereby ensuring the stability of the quarter brick 160.

[0050] In this technical solution, in order to ensure the stacking stability of the solid energy storage body structure 100, the complete energy storage body 110 structure has at least six rows of protrusions in the horizontal direction. At the same time, in order to ensure the contact area of ​​the upper and lower solid energy storage body structures 100, the protrusions should not exceed ten rows in the horizontal direction. Figure 1 In the illustrated embodiment, there are six columns of positioning blocks 130 in the whole brick.

[0051] Wherein, the solid energy storage body structure also includes a raised bar, which is arc-shaped and arranged on the bottom surface of the pancake-shaped heat-conducting half hole.

[0052] This technical solution increases the heat exchange area of ​​the pan-shaped heat-conducting half hole 120 and increases the heat exchange efficiency without affecting the energy storage space of the solid energy storage body structure 100 by arranging raised strips on the pan-shaped heat-conducting half hole 120 to imitate the depressions on the upper and lower surfaces of red blood cells.

[0053] It can be understood that in the embodiment where the solid energy storage body structure 100 has an installation side hole 140, the shape of the raised strip is adapted according to the top and bottom surfaces of the installation side hole. In this embodiment, the raised strip arranged on the top and bottom surfaces of the installation side hole 140 is half of the raised strip arranged on the pan-shaped thermal conductive half hole 120.

[0054] In an embodiment where the solid energy storage body structure 100 is a half brick 150 or a quarter brick 160, the shape of the raised strip is adapted according to the shapes of the half brick 150 and the quarter brick 160. In this embodiment, the shape of the raised strip arranged on the half brick 150 is half of the shape of the raised strip arranged on the pie-shaped heat conductive half hole 120, and the shape of the raised strip arranged on the quarter brick 160 is one quarter of the shape of the raised strip arranged on the pie-shaped heat conductive half hole 120.

[0055] like Figure 8 , Fig. 9 , Fig.15 As shown, according to the second aspect of the embodiment of the present application, a stacking method is proposed, wherein the surfaces of the solid energy storage structure 100 with the pancake-shaped heat-conducting half holes 120 are stacked relative to each other; Step 101: The surfaces of the solid energy storage structure 100 with the pancake-shaped heat-conducting half holes 120 are stacked relative to each other; The solid energy storage body structure 100 is stacked to form a solid energy storage device 200; Step 102: define the bottom layer of the solid energy storage device 200 as the first layer, the opening ends of the pancake-shaped heat-conducting half holes 120 of the solid energy storage body structure 100 of odd-numbered layers face upward, and the opening ends of the pancake-shaped heat-conducting half holes 120 of the solid energy storage body structure 100 of even-numbered layers face downward; Step 103: When stacking, the adjacent solid energy storage structures 100 in the Z-axis direction are mutually limited by positioning blocks 130; Step 104: When stacking, the solid energy storage body structures 100 are arranged in a staggered manner; Step 105: the solid energy storage device 200 can be disassembled into a whole brick of the solid energy storage structure 100, a half brick 150 of the solid energy storage structure 100, and a quarter brick 160 of the solid energy storage structure 100; Step 106: When the solid energy storage device is stacked to the edge, a half-brick of the solid energy storage body structure 100 and a quarter-brick 160 of the solid energy storage body structure 100 can be used according to usage requirements.

[0056] In this technical solution, the surfaces of the solid energy storage structure 100 with the pancake-shaped heat-conducting half holes 120 are stacked relatively. This arrangement can ensure that the two pancake-shaped heat-conducting half holes 120 are arranged relatively, leaving enough space for the arrangement of the resistance wire.

[0057] Furthermore, the bottom layer is defined as the first layer, and the opening ends of the pancake-shaped heat-conducting half holes 120 of the odd-numbered layers of the solid energy storage body structure 100 are upward, and the opening ends of the pancake-shaped heat-conducting half holes 120 of the even-numbered layers of the solid energy storage body structure 100 are downward. This setting ensures that the pancake-shaped heat-conducting half holes 120 of the bottom layer of the solid energy storage body structure 100 will not touch the ground. At the same time, when a single pancake-shaped heat-conducting half hole 120 cannot realize the installation function, the situation where the resistance wire cannot be installed in the bottom layer will not occur.

[0058] Furthermore, when stacked, the adjacent solid energy storage body structures 100 in the Z-axis direction are limited to each other by the positioning blocks 130, and the solid energy storage body structures 100 are connected into one by the positioning blocks 130, which can effectively avoid thermal displacement of the energy storage body, improve the overall strength, and effectively prevent the thermal displacement problem when the temperature difference changes, thereby improving the reliability of the overall energy storage body and the energy storage effect.

[0059] Furthermore, the solid energy storage body structure 100 is staggered. When stacking, the solid energy storage body structure 100 is staggered in both the Y-axis and X-axis directions, and the staggered amount is one-half. This setting can make the energy storage body stack more stable. At the same time, the staggered arrangement can make the positioning block 130 not only strengthen the longitudinal connection of the solid energy storage body structure 100, but also strengthen the lateral connection of the solid energy storage body structure 100.

[0060] It can be understood that when the energy storage body is staggered, the pancake-shaped heat-conducting half hole 120 can be set as a through hole that can independently carry the installation resistance wire, or as shown in the present embodiment, installation side holes 140 can be set along both sides of the pancake-shaped heat-conducting half hole 120 of the solid energy storage body structure 100, so that one pancake-shaped heat-conducting half hole 120 cooperates with two installation side holes 140 to form a pancake-shaped heat-conducting through hole.

[0061] In actual use, after using the brick type and stacking method of the present invention, the overall stability and thermal displacement resistance are significantly increased, which can effectively restrain the thermal displacement caused by thermal expansion and contraction. The comprehensive evaluation can reach more than 20 times that of ordinary flat bricks, and the service life is greatly extended.

[0062] like Fig. 9 As shown, it also includes: the solid energy storage structure 100 can be split into half bricks 150 and quarter bricks 160; when the solid energy storage structure 100 is stacked to the edge, half bricks 150 and quarter bricks 160 can be used according to usage requirements.

[0063] In this technical solution, when the solid energy storage structure 100 is staggered, there will always be gaps at its edges and four corners. At this time, half bricks 150 or quarter bricks 160 are used to fill the gaps according to the positions of the gaps. This method further enhances the stability of the stacking.

[0064] like Fig. 9 As shown, according to the third aspect of the embodiment of the present application, a solid energy storage device 200 is proposed. The solid energy storage device 200 is an energy storage stack with stacking performance by a solid energy storage body structure 100 through a stacking method. It can be applied to energy storage in the fields of wind power, photovoltaic clean energy, etc., and has the advantages of stable stacking, resistance to thermal expansion and contraction, and fast heat dissipation.
