Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solid heat storage, and particularly relates to a sealing structure for a carbon brick heat storage material brick body. Background Technique
[0002] Since carbon bricks are extremely easy to oxidize at high temperatures, but due to their superiority in specific heat, thermal conductivity, etc., they can generally be used as heat storage materials. During use, air cannot be used as the circulating medium. Currently, nitrogen is generally used as the circulating medium. However, when the solid heat storage device heats and releases heat, the volume inside the system will expand and contract. Therefore, nitrogen needs to be continuously released and compensated into the system, resulting in waste of nitrogen and a more complex system design. Content of the Utility Model
[0003] The purpose of the utility model is to provide a sealing structure for a carbon brick heat storage material brick body to solve the problems proposed in the above background technique, that is, currently nitrogen is generally used as the circulating medium, but when the solid heat storage device heats and releases heat, the volume inside the system will expand and contract. Therefore, nitrogen needs to be continuously released and compensated into the system, resulting in waste of nitrogen and a more complex system design.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A sealing structure for a carbon brick heat storage material brick body, including a sealing brick layer. The sealing brick layer forms a cuboid shell structure. There is a sealing gap between the bricks of the sealing brick layer. The inside of the sealing gap is filled with a sealing filler. Ceramic fiber paper is provided on the upper and lower outer surfaces of the sealing brick layer. Heat storage bricks with holes and flat heat storage bricks are stacked in sequence inside the sealing brick layer. The heat storage bricks with holes and the flat heat storage bricks are arranged in a form of staggering joints. There is a through groove between the heat storage bricks with holes. An insulating tube is provided inside the through groove. Both ends of the insulating tube penetrate through the sealing brick layer and extend to the outside of the sealing brick layer.
[0005] Preferably, the ceramic fiber paper is fixedly arranged on the upper and lower outer surfaces of the sealing brick layer through the sealing filler.
[0006] Preferably, the heat storage bricks with holes and the flat heat storage bricks have the same thickness. The insulating tube is a square tube structure with a square cross-section. The outer side length dimension of the insulating tube is the same as the thickness of the heat storage bricks with holes.
[0007] Preferably, the size of the sealing brick layer is smaller than the sizes of the heat storage bricks with holes and the flat heat storage bricks. The numerical value by which the size of the sealing brick layer is smaller than the sizes of the heat storage bricks with holes and the flat heat storage bricks is the size of the sealing gap.
[0008] Preferably, the sealing filler is filled into the sealing gap inside between the insulating tube and the sealing brick layer.
[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: When this patent aims at using carbon bricks as the heat storage material of a solid electric heat storage device and air as the circulating medium, it solves the problem of carbon brick oxidation. Generally, this patent adopts a sealed structure on all six faces of the heat storage brick body, ensuring that the carbon bricks inside the brick body do not come into contact with air, so that the carbon bricks will not be oxidized during heating, avoiding damage to the heat storage material, and making the system design simpler.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figures 1-5 , the present utility model provides a sealed structure for a carbon brick heat storage material brick body, including a sealed brick layer 1. The sealed brick layer 1 constitutes a cuboid shell structure. There is a sealed joint 2 between the bricks of the sealed brick layer 1. The inside of the sealed joint 2 is provided with a sealed filling 3. Ceramic fiber paper 4 is provided on both the upper and lower outer surfaces of the sealed brick layer 1. Hole layer heat storage bricks 5 and laid heat storage bricks 6 are sequentially stacked inside the sealed brick layer 1. The hole layer heat storage bricks 5 and the laid heat storage bricks 6 are both arranged in a seam-pressing form. There is a through groove 7 between the hole layer heat storage bricks 5. An insulating tube 8 is provided inside the through groove 7. Both ends of the insulating tube 8 penetrate through the sealed brick layer 1 and extend to the outside of the sealed brick layer 1.
[0018] During use, a rectangular shell structure is formed by the sealed brick layer 1. The sealed brick layer 1 is made of oxidation-resistant bricks, and the material is magnesia brick or high-alumina brick. A sealing joint 2 is provided between the bricks of the sealed brick layer 1, and a filling space is left for the sealing filling 3 through the sealing joint 2, so as to avoid the problem that the sealing filling 3 causes the gap between the bricks to expand, resulting in the irregular arrangement of the sealed brick layer 1, and avoid the problem that the size of the sealed brick layer 1 is larger than that of the hole-layer regenerative brick 5 and the flat-laid regenerative brick 6, resulting in an increase in the internal gap of the regenerative device. The sealing filling 3 fills the sealing joint 2, so that the sealed brick layer 1 forms a sealed shell structure, thereby sealing the structure inside the sealed brick layer 1. The hole-layer regenerative brick 5 and the flat-laid regenerative brick 6 are sequentially arranged inside the sealed brick layer 1. The hole-layer regenerative brick 5 and the flat-laid regenerative brick 6 are both carbon bricks. The hole-layer regenerative brick 5 and the flat-laid regenerative brick 6 are arranged in a butted joint form without gaps between them. A through groove 7 is provided between the hole-layer regenerative bricks 5, and a space is left for the installation of the insulating tube 8 through the through groove 7. A heating structure such as an electric heating wire is arranged inside the insulating tube 8. The heat is stored in the hole-layer regenerative brick 5 and the flat-laid regenerative brick 6 through the heating structure such as the electric heating wire. When heat release is required, air is introduced into the insulating tube 8, so as to output the heat stored in the hole-layer regenerative brick 5 and the flat-laid regenerative brick 6 to the outside.
[0019] The ceramic fiber paper 4 is fixedly arranged on the upper and lower outer surfaces of the sealed brick layer 1 through the sealing filling 3. The ceramic fiber paper 4 is arranged on the upper and lower outer surfaces of the sealed brick layer 1 through the sealing filling 3, so as to improve the strength of the upper and lower outer surfaces of the sealed brick layer 1.
[0020] The thickness of the hole-layer regenerative brick 5 is the same as that of the flat-laid regenerative brick 6. The insulating tube 8 has a square tube structure with a square cross-section. The outer side length dimension of the insulating tube 8 is the same as the thickness of the hole-layer regenerative brick 5. Through the hole-layer regenerative brick 5, the flat-laid regenerative brick 6 and the insulating tube 8 with the same thickness design, the overall regenerative structure is ensured to be regular, and the gap between the bricks is reduced.
[0021] The size of the sealed brick layer 1 is smaller than the sizes of the hole-layer regenerative brick 5 and the flat-laid regenerative brick 6. The numerical value of the size of the sealed brick layer 1 being smaller than the sizes of the hole-layer regenerative brick 5 and the flat-laid regenerative brick 6 is the size of the sealing joint 2. By reducing the size of the sealed brick layer 1, a sealing joint 2 is left between the bricks of the sealed brick layer 1, and a space is left for the filling of the sealing filling 3.
[0022] The sealing filling 3 is filled into the sealing joint 2 between the insulating tube 8 and the sealed brick layer 1, and the space between the insulating tube 8 and the sealed brick layer 1 is sealed through the sealing filling 3.
[0023] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
