Description

Technical Field

[0001] The present invention belongs to the technical field of energy conservation and environmental protection, and relates to a masonry structure of a solid energy storage body. The present invention is a solid energy storage body constructed by using energy storage bricks in the form of interval embedded mortise and tenon structures, which can improve the structural strength of the energy storage body and is suitable for the masonry structure of a solid energy storage body working at high temperatures. Background Art

[0002] In recent years, with the rapid development of my country's energy-saving and environmental protection industry, solid electric heat storage devices have been widely used in various industrial and domestic heat uses. It can achieve the effect of "peak shaving and valley filling" of the power grid, use and save energy reasonably, and reduce harmful gas emissions and environmental pollution. In the prior art, the solid energy storage body, one of the core components of the solid electric heat storage device, is built with bricks sintered at a high temperature of more than 1100°C. Since the solid energy storage body works under high temperature conditions, the maximum temperature can usually reach 800~1000 degrees, and it frequently stores and releases heat, and the temperature difference is particularly large, which may cause its overall structure to deform due to expansion, and cracking due to contraction, resulting in the overall stability of the energy storage body being destroyed. In severe cases, the energy storage body may collapse. Especially for solid energy storage bodies near the ventilation duct, the above problems are particularly prominent.

[0003] Prior art, such as the authorized patent No. 201410617029.4, discloses a slot-type solid heat storage body structure, including a first heat storage brick body and a second heat storage brick body, with a ventilation duct D provided on the brick body, and a slot A and a slot on both sides of the ventilation duct D. The engagement of the brick bodies is ensured by matching the convex and concave holes formed by the two heat storage bodies, and the overall stability of the heat storage body is ensured when the overall structure is high. However, the brick bodies in this solution are all special brick bodies, and the brick bodies are provided with multiple structures of different sizes and uses, which are complex in structure, difficult to process, and have a high rate of damage during transportation. Local procurement is not possible, which increases transportation costs.

[0004] The masonry bricks of energy storage bodies are generally divided into standard energy storage bricks and special-shaped customized bricks. That is, the standard energy storage bricks of all domestic energy storage brick manufacturers uniformly comply with national standards, and the specifications and other parameters are basically the same. The market supply is large and the region is wide; special-shaped customized bricks are often produced by energy storage brick manufacturers according to special molds according to customer needs, with low output and small regional scope, which is not convenient for large-scale and long-distance supply. Summary of the invention

[0005] The purpose of the present invention is to provide a masonry structure of a solid energy storage body to solve the problems in the prior art.

[0006] To achieve the above-mentioned purpose, the present invention is achieved through the following technical means: a masonry structure of a solid energy storage body, characterized in that: it includes a wire-bearing layer, a wire-arranging layer, and a covering wire layer formed by the masonry of multiple energy storage bodies; a hole is provided on the wire-arranging layer for placing heating wires and ventilation; the energy storage bricks in the wire-arranging layer are arranged longitudinally, the energy storage bricks in the first and last rows are special-shaped energy storage bricks, and the standard energy storage bricks and special-shaped energy storage bricks in the middle column are arranged at intervals; the energy storage bricks in the covering wire layer are arranged transversely, the energy storage bricks in the first and last rows are special-shaped energy storage bricks, and the standard energy storage bricks and special-shaped energy storage bricks in the middle column are arranged at intervals; the special-shaped energy storage bricks are energy storage bricks with mortise and tenon structures, and mortise and tenon grooves are provided at both ends of the brick body, and mortise and tenon parts are embedded in the mortise and tenon grooves corresponding to two adjacent special-shaped energy storage bricks.

[0007] Further: the staggered arrangement of standard energy storage bricks and special-shaped energy storage bricks means that 2-3 rows / columns of standard energy storage bricks are arranged between every 2 rows / columns of special-shaped energy storage bricks.

[0008] Furthermore: the mortise and tenon are filled with glue to play the role of fixing and packaging.

[0009] Furthermore: the mastic is a mixture of ordinary high temperature mastic, high temperature fiber mastic and antifreeze high temperature mastic.

[0010] Compared with the existing structure, the advantages of the present invention are: 1. When the energy storage body expands due to temperature increase, the mortise and tenon connection structure can restrain the expansion displacement of the energy storage brick, so that the relative position of two adjacent energy storage bricks remains unchanged, thereby achieving the purpose of improving the overall stability of the energy storage body.

[0011] 2. Since only the wire arrangement layer and the cover wire layer are arranged in an intermittent manner, the number of special-shaped energy storage bricks with mortise and tenon structures used in the overall energy storage body structure is no more than 20% of the number of overall energy storage bricks used. Compared with the use of all special-shaped bricks, the number of off-site supplies is greatly reduced, which not only saves transportation costs but also ensures construction time.

[0012] 3. In this scheme, different layers can be built in a longitudinal and transverse staggered manner, which improves the overall stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] like Figure 1-3 The figure shows a masonry structure of a solid energy storage body of the present invention, which adopts a spaced embedded mortise and tenon structure energy storage brick combined with a standard energy storage brick. On the basis of the energy storage body, the energy storage body is masonry-built in the structural order of a wire-bearing layer 1, a wire-arranging layer 2, and a wire-covering layer 3, wherein a hole 4 for placing a heating wire is left between two rows of energy storage bricks in the wire-arranging layer 2, which serves as both a structure for placing a heating wire 5 and a ventilation channel. The wire-bearing layer 1 is entirely made of standard energy storage bricks 6; the wire-arranging layer 2 energy storage bricks are arranged longitudinally, wherein the first and last rows are entirely made of special-shaped energy storage bricks 7 with mortise and tenon structures, and mortise and tenon parts 8 are used between the brick bodies to be embedded in the mortise and tenon of the special-shaped energy storage bricks 7, and the remaining rows in the middle are arranged every 2-3 rows, using standard energy storage bricks 6 and special-shaped energy storage bricks 7 at intervals; the wire-covering layer 3 energy storage bricks are arranged transversely, wherein the first and last rows are entirely made of special-shaped energy storage bricks 7 with mortise and tenon structures, and mortise and tenon parts 8 are used between the brick bodies to be embedded in the mortise and tenon of the special-shaped energy storage bricks 7, and the remaining rows in the middle are arranged every 2-3 rows, using standard energy storage bricks 6 and special-shaped energy storage bricks 7 at intervals.

[0020] The mortise and tenon parts 8 are dumbbell-shaped or double dovetail-shaped, and are made of metal or ceramic components. They are embedded in the mortise and tenon grooves of two adjacent special-shaped energy storage bricks 7, and the two special-shaped energy storage bricks are connected by clamping, and the mortise and tenon grooves are filled with glue to play the role of fixing and packaging. The glue can be the existing ordinary glue, or it can be a mixture of multiple glues, such as a mixed glue containing ordinary high-temperature glue, high-temperature fiber glue and antifreeze high-temperature glue. Among them, ordinary high-temperature glue is a special glue that is operable between the ambient temperature of 5°C and 50°C, and has bonding strength under the working temperature of 200°C to 800°C; high-temperature fiber glue is a special glue that is added to a certain proportion of fiber material in ordinary high-temperature glue to improve the bonding strength of the glue without changing other properties; antifreeze high-temperature glue is a professional glue that is operable between the ambient temperature of -20°C and 50°C, and has good bonding strength under the working temperature of 200°C to 800°C. In this solution, the end of the mortise and tenon piece cooperates with the mortise and tenon groove to transfer the force between two adjacent energy storage bricks. When heated, the front end of the mortise and tenon piece (the end facing the center of the energy storage brick) contacts the energy storage brick, transferring the pressure between the two energy storage bricks to the center of the energy storage brick, reducing the pressure between the contact surface of the two energy storage bricks, i.e., the brick joints, and effectively reducing the degree of thermal deformation. When cooled, the rear end of the mortise and tenon piece (the end facing the brick joints) contacts the energy storage brick, which is equivalent to pulling the two adjacent energy storage bricks together, resisting the contraction force of the energy storage bricks, reducing the tension between the contact surface of the two energy storage bricks, i.e., the brick joints, and effectively reducing the degree of enlargement of the gap between adjacent energy storage bricks after cooling, reducing the possibility of cracking, and improving the overall strength and service life. Therefore, the ability of the entire masonry to resist deformation and cracking is improved.

[0021] The use process of the present invention is as follows: in the process of implementing the energy storage body masonry, according to the needs, at specific positions (wire arrangement layer and cover wire layer), special-shaped energy storage bricks with mortise and tenon structures are used for masonry, two adjacent special-shaped energy storage bricks with mortise and tenon structures are matched to form a mortise, and then the mortise and tenon parts are placed in the mortise according to regulations, and then special glue is injected into the mortise to fix the mortise and tenon parts in the glue, and finally the standard energy storage bricks 6 and the special-shaped energy storage bricks 7 with mortise and tenon structures of the upper layer are masonry together with the standard energy storage bricks 6 and the special-shaped energy storage bricks with mortise and tenon structures of the lower layer using special glue. After the structure described in the present invention is installed, the mortise and tenon parts connect multiple special-shaped energy storage bricks with mortise and tenon structures into one, increase their bearing capacity during thermal expansion, improve the overall strength, and effectively prevent the cracking problem at the connection when the temperature difference changes, thereby improving the strength and service life of the overall energy storage body, as well as the energy storage effect.

[0022] In actual use, an electric heat storage furnace for deep peak regulation of power plants is selected, with a power of 320MW and 20,000 tons of energy storage bricks. When the structure described in the present invention is used for masonry, 16,000 tons of standard energy storage bricks can be obtained locally, and the amount of special-shaped energy storage bricks used to strengthen the structural strength is only about 4,000 tons. The localization rate of raw materials exceeds 80%, which can greatly save the transportation cost of bricks and the storage cost of materials, and can also increase the construction speed of equipment, ensure the construction time, and ensure delivery. After masonry according to the present invention, the overall strength increases significantly, which can effectively restrain the structural deformation caused by expansion, and the resistance to cracking and deformation is enhanced. The comprehensive evaluation can reach 5-6 times that of the original structure, and the service life is greatly extended.

[0023] Finally, it should be noted that the above specific implementation modes are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail, those skilled in the art should understand that the implementation modes of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the implementation modes of the present invention, which should all be included in the scope of the claims of the present invention.
