Description
An industrial furnace heat storage body having a sidewall with oriented topology
Technical field
[0001] The present invention relates to the field of energy saving in industrial furnaces, and more particularly relates to an industrial furnace heat storage body having a sidewall with oriented topology.
Background art
[0002] Regarding industrial heating furnaces, the chief mode of heat transmission of the flame within the combustion chamber to the heated workpiece or pipes is radiation; such furnaces are therefore commonly called industrial radiation furnaces. In the industrial heating furnace, a large amount of thermal radiation can be generated when a flame is produced within the combustion chamber; of this radiation, the rays of thermal radiation that directly strike the heated workpiece or pipes may be directly absorbed by the workpiece or pipes; there are also rays of thermal radiation that are scattered onto the internal wall of the combustion chamber and reflected by the internal wall of the combustion chamber, before striking the heated workpiece or pipes and being absorbed by the workpiece or pipes.
[0003] Prior art CN209279239U discloses an intelligent solid storage electric furnace and a solid storage electric furnace assembly, in which two solid heat storage bodies are adjacently arranged, with a gap in the forwards/rearwards direction, within a refractory thermally insulated furnace body, restricting absorption and reflection of thermal radiation rays by the inside wall of the combustion chamber of the industrial furnace and consequently influencing the heat transmission efficiency.
[0004] In order to improve and optimise the thermal radiation absorption and reflection characteristics of the inside wall of the combustion chamber of a current industrial furnace, so that more of the thermal radiation rays can be absorbed by the workpiece or pipes after ample reflection by the inside wall of the combustion chamber during passage therethrough, we therefore propose an industrial heat storage body provided with a sidewall with oriented topology.
Content of the Utility Model [0005] In this regard, the present utility model provides an industrial furnace heat storage body including a heat storage body main body comprising sidewall oriented topology structures, the heat storage body main body being arranged on the inside wall of the combustion chamber of the industrial furnace; wherein the heat storage body main body is of cuboidal construction; the heat storage body main body includes a first sidewall and a second sidewall that are oppositely arranged along a first direction, and a third sidewall and a fourth sidewall that are oppositely arranged along a second direction, the first direction intersecting the second direction, and the first direction being the direction perpendicular to the plane where the first sidewall is located, the first sidewall being a sidewall facing the flame and heated workpiece in the interior of the combustion chamber, there being provided, only on the first sidewall surface, projection topology structural units that are disposed along the second direction and extend in the first direction; the projection topology structural units being pillar structures; the projection topology structural units comprising a top face and bottom face that are oppositely arranged along the first direction, the top face being located on the side of the projection topology structural unit remote from the second sidewall, the orthogonally projected area of the top face on the second sidewall being smaller than the orthogonally projected area of the bottom face on the second sidewall; the total surface area of the projection topology structural units being at least five times greater than the contour area of the heat storage body main body side face.
[0006] Preferably, the first sidewall comprises cavities recessed in one side of the second sidewall, the cavities being pillar structures, the cavities being matched with the projection topology structural units, the projection topology structural units being nested in the cavities, the surface area of the projection topology structural units and the total surface area within the cavities being at least five times greater than the contour area of the side face of the heat storage body main body.
[0007] Preferably, a first interval is formed between two adjacent projection topology structural units.
[0008] Preferably, along the first direction, the height of the projection topology structural units is smaller than or equal to the depth of the cavities.
[0009] The present utility model also provides an industrial furnace heat storage body including a heat storage body main body comprising sidewall oriented topology structures, the heat storage body main body being arranged on the inside wall of the combustion chamber of the industrial furnace; the heat storage body main body is of cuboidal construction; the heat storage body main body includes a first sidewall and a second sidewall that are oppositely arranged along a first direction, and a third sidewall and a fourth sidewall that are oppositely arranged along a second direction, the first direction intersecting the second direction, and the first direction being the direction perpendicular to the plane where the first sidewall is located, the first sidewall being a sidewall facing the flame and heated workpiece in the interior of the combustion chamber, there being provided, only on the first sidewall surface, cavities recessed in one side of the second sidewall; the cavities being pillar structures; the total inside surface area of the cavities being at least five times greater than the contour area of the heat storage body main body side face.
[0010] Preferably a second interval is formed between two adjacent cavities.
[0011] Preferably the heat storage body main body, the projection topology structural units and the cavities are made of heat-resistant material.
[0012] Compared with current technology, the industrial furnace heat storage body comprising sidewall oriented topology structures according to the present utility model achieves at least the following beneficial effects: [0013] Thanks to the provision of the industrial furnace heat storage body comprising sidewall oriented topology structures, under unchanged flame conditions of the combustion chamber, by expanding the actual reflective area of the industrial furnace inside wall for the thermal radiation rays, the efficiency of reflection of the flame thermal radiation by the inside wall of the combustion chamber of the industrial furnace is raised, so that, after the flame thermal radiation rays from the interior of the furnace combustion chamber have reached the surface of this heat storage body comprising sidewall oriented topology structures, ample reflection takes place at the actual extended surface of the topological structures so that these reflected rays strike the workpiece or pipes and are consequently absorbed by the workpiece. Under the same thermal radiation environment, the use of a heat storage body having sidewall oriented topology structures for cladding the inside wall enables the actual extent of the overall surface area of the sidewall surface when the heat storage body main body has such oriented topology structures to greatly exceed, by at least five times, that which would be obtained from the contour projection surface of the sidewall surfaces without these oriented topology structures. Thus the inside wall of the combustion chamber provides a higher intensity of radiation and the reflection efficiency of the inside wall of the combustion chamber of the industrial furnace for thermal radiation is increased, raising the overall heat transfer efficiency of the industrial heating furnace and so achieving an energy saving and emission reduction effect.
[0014] Of course, implementation of any particular product according to the utility model does not necessarily imply simultaneous achievement of all of the technical benefits described above.

[0023] In all the examples illustrated and discussed herein all specific values must be regarded as merely exemplary and not restrictive. Practical examples other than the illustrative examples may therefore have different values.
[0024] It should be noted that: similar reference symbols and letters indicate similar items in the subsequent appended drawings; consequently, once a given item has been defined in one appended drawing, it does not need to be further discussed in the subsequent appended drawings. [0025] Embodiment 1 [0026] As shown in Fig. 1, the present embodiment provides an industrial furnace heat storage body 000 comprising a sidewall oriented topology structure, including a heat storage body main body 1; the heat storage body main body 1 is arranged on the inside wall of the combustion chamber of an industrial furnace (not shown). The heat storage body main body 1 has a cuboidal construction. The heat storage body main body 1 includes a first sidewall 6 and a second sidewall 7 oppositely arranged along a first direction Y, and a third sidewall 8 and fourth sidewall 9 oppositely arranged along a second direction X, the first direction Y intersecting the second direction X; the first direction Y is perpendicular to the direction of the plane in which the first sidewall 6 is located; the first sidewall 6 is a sidewall facing the flame and heated workpiece in the interior of the combustion chamber. Only on the surface of the first sidewall 6, there are provided projection topology structural units 2 arranged in the second direction X and extending in the first direction Y. The projection topology structural units 2 have a pillar structure. The projection topology structural units 2 comprise a top face and a bottom face that are oppositely arranged in the first direction Y. The top face is positioned on the side of the projection topology structural unit that is remote from the second sidewall 7, and the orthogonally projected area of the top face on the second sidewall 7 is smaller than the orthogonally projected area of the bottom face on the second sidewall 7. The directions of the central normals of the projection topology structural units 2 are all mutually parallel and all face the interior of the combustion chamber on the direction of extension of the central normals. A first interval 4 is formed between two adjacent projection topology structural units 2. The result of this is that the actual extent of the total surface area of the first sidewall 6 of the heat storage body provided with the heat storage body main body land projection topology structural units 2 is very much larger, at least five times or more, than that of the surface contour area of the first sidewall 6 of a heat storage body in a condition wherein the heat storage body main body land projection topology structural units 2 are not provided.
[0027] Optionally, depending on the actual flame temperature of the combustion chamber, the heat storage body main body land the projection topology structural units 2 are both made of heat-resistant material. Specifically, the heat-resistant material may be refractory ceramic fibre, high-alumina brick, mullite or silicon carbide or the like material.
[0028] It must be explained that Fig. 1 of the present embodiment merely conceptually depicts the case where the projection topology structural units 2 of the surface of the first sidewall 6 are of quadrangular pillar shape; however there is no restriction to this, and the projection topology structural units 2 of the surface of the first sidewall 6 could be of pentangular pillar shape, hexagonal pillar shape, or cylindrical shape. In actual implementation, regarding the dimensions of the heat storage body main body 1 cuboid, and the shape, number and dimensions of the projection topology structural units 2 of the surface of its first sidewall 6, so long as the condition that the extent of the area of the side faces of the pillars of the heat storage body main body is very much larger, at least five times or more, than that of the contour area of the side faces of the pillars, is satisfied, these can be determined based on the strength of the materials and the manufacturing technology of the heat storage body and the actual parameters of the combustion chamber of the furnace: the present embodiment has no specific restrictions in this regard. The larger the number of sides of the polygons of the bottom faces of the polygonal pillars constituted by the projection topology structural units 2 on the surface of the first sidewall 6, the larger is the actual extent of the overall surface area of these oriented projection topology structural units on the sidewall surface of the heat storage body main body 1, with result that the efficiency of reflection of thermal radiation by the inside wall of the combustion chamber of the industrial furnace is raised and the overall efficiency of heat transmission of the industrial heating furnace is thereby raised, thus achieving energy saving and emission reduction.
[0029] Embodiment 2 [0030] As shown in Fig. 2, the present embodiment provides an industrial furnace heat storage body 000 comprising a sidewall oriented topology structure, including a heat storage body main body 1; the heat storage body main body 1 is arranged on the inside wall of the combustion chamber of an industrial furnace (not shown). The heat storage body main body 1 has a cuboidal construction. The heat storage body main body 1 includes a first sidewall 6 and a second sidewall 7 oppositely arranged along a first direction V. and a third sidewall 8 and fourth sidewall 9 oppositely arranged along a second direction X, the first direction Y intersecting the second direction X; the first direction le is perpendicular to the direction of the plane in which the first sidewall 6 is located; the first sidewall 6 is a sidewall facing the flame and heated workpiece in the interior of the combustion chamber. Only on the surface of the first sidewall 6, there are provided cavities 3 recessed towards one side of the second sidewall 7. The cavities 3 have a pillar structure. The directions of the central normals of the cavities 3 are all mutually parallel and all face the interior of the combustion chamber on the direction of extension of the central normals. A second interval 5 is formed between two adjacent cavities 3. The result of this is that the actual extent of the total surface area of the first sidewall 6 of the heat storage body provided with the heat storage body main body 1 and cavities 3 is very much larger, at least five times or more, than that of the surface contour area of the first sidewall 6 of a heat storage body in a condition wherein the heat storage body main body 1 and cavities 3 are not provided.
[0031] Optionally, depending on the actual flame temperature of the combustion chamber, the heat storage body main body 1 and the cavities 3 are both made of heat-resistant material. Specifically, the heat-resistant material may be refractory ceramic fibre, high-alumina brick, mullite or silicon carbide or the like material.
[0032] It must be explained that Fig. 2 of the present embodiment merely conceptually depicts the case where the cavities 3 of the surface of the first sidewall 6 are of quadrangular pillar shape; however there is no restriction to this, and the cavities 3 of the surface of the first sidewall 6 could be of pentangular pillar shape, hexagonal pillar shape, or cylindrical shape. In actual implementation, regarding the dimensions of the heat storage body main body 1 cuboid, and the shape, number and dimensions of the cavities 3 of the surface of its first sidewall 6, so long as the condition that the extent of the area of the side faces of the pillars of the heat storage body main body is very much larger, five times or more, than that of the contour area of the side faces of the pillars, is satisfied, these can be determined based on the strength of the materials and the manufacturing technology of the heat storage body and the actual parameters of the combustion chamber of the furnace: the present embodiment has no specific restrictions in this regard. The larger the number of sides of the polygons of the bottom faces of the polygonal pillars constituted by the cavities 3 in the surface of the first sidewall 6, the larger is the actual extent of the overall surface area of these oriented cavity topology structures on the sidewall surface of the heat storage body main body 1, and the efficiency of reflection of thermal radiation by the inside wall of the combustion chamber of the industrial furnace is raised and the overall efficiency of heat transmission of the industrial heating furnace is thereby raised, thus achieving an energy saving and emission reduction effect.
[0033] Embodiment 3 [0034] As shown in Fig. 3, the present embodiment provides an industrial furnace heat storage body 000 comprising a sidewall oriented topology structure, including a heat storage body main body 1; the heat storage body main body 1 is arranged on the inside wall of the combustion chamber of an industrial furnace (not shown). The heat storage body main body 1 has a cuboidal construction. The heat storage body main body 1 includes a first sidewall 6 and a second sidewall 7 oppositely arranged along a first direction Y, and a third sidewall 8 and fourth sidewall 9 oppositely arranged along a second direction X, the first direction Y intersecting the second direction X; the first direction Y is perpendicular to the direction of the plane in which the first sidewall 6 is located; the first sidewall 6 is a sidewall facing the flame and heated workpiece in the interior of the combustion chamber. Only on the surface of the first sidewall 6, there are provided projection topology structural units 2 arranged in the second direction X and extending in the first direction Y, and cavities 3 recessed in one side of the second sidewall 7. The projection topology structural units 2 and cavities 3 both have a pillar structure. The projection topology structural units 2 comprise a top face and a bottom face that are oppositely arranged in the first direction Y. The top face is positioned on the side of the projection topology structural unit that is remote from the second sidewall 7, and the orthogonally projected area of the top face on the second sidewall 7 is smaller than the orthogonally projected area of the bottom face on the second sidewall 7.
The projection topology structural units 2 and the cavities 3 are matched, a projection topology structural unit 2 of comparatively small dimensions being nested in a cavity 3. In said first direction, the height of the projection topology structural units 2 is less than or equal to the depth of the cavities 3. The directions of the central normals of the projection topology structural units 2 and the cavities 3 are all mutually parallel and all face the interior of the combustion chamber on the direction of extension of the central normals. A first interval 4 is formed between two adjacent projection topology structural units 2. A second interval 5 is formed between two adjacent cavities 3. The result of this is that the actual extent of the total surface area of the first sidewall 6 of the heat storage body provided with the heat storage body main body 1, projection topology structural units 2 and cavities 3 is very much larger, at least five times or more, than that of the surface contour area of the first sidewall 6 of a heat storage body in a condition wherein the heat storage body main body 1, projection topology structural units 2 and cavities 3 are not provided.
[0035] Optionally, depending on the actual flame temperature of the combustion chamber, the heat storage body main body 1, the projection topology structural units 2 and the cavities 3 are made of heat-resistant material. Specifically, the heat-resistant material may be refractory ceramic fibre, high-alumina brick, mullite or silicon carbide or the like material. [0036] It must be explained that Fig. 3 of the present embodiment merely conceptually depicts the case where projection topology structural units 2 and the cavities 3 of the surface of the first sidewall 6 are of quadrangular pillar shape; however there is no restriction to this, and projection topology structural units 2 and the cavities 3 of the surface of the first sidewall 6 could be of pentangular pillar shape, hexagonal pillar shape, or cylindrical shape. In actual implementation, regarding the dimensions of the heat storage body main body 1 cuboid, and the shape, number and dimensions of projection topology structural units 2 and the cavities 3 of the surface of its first sidewall 6, so long as the condition that the extent of the area of the side faces of the pillars of the heat storage body main body is very much larger, five times or more, than that of the contour area of the side faces of the pillars, is satisfied, these can be determined based on the strength of the materials and the manufacturing technology of the heat storage body and the actual parameters of the combustion chamber of the furnace: the present embodiment has no specific restrictions in this regard. The larger the number of sides of the polygons of the bottom faces of the polygonal pillars constituted by projection topology structural units 2 and the cavities 3 in the surface of the first sidewall 6, the larger is the actual extent of the overall surface area of these structural units with sidewall oriented cavity-nested projection topology on the sidewall surface of the heat storage body main body 1, and so the efficiency of reflection of thermal radiation by the inside wall of the combustion chamber of the industrial furnace is raised and the overall efficiency of heat transmission of the industrial heating furnace is raised, thus achieving energy saving and emission reduction.
[0037] From the embodiments described above it can be seen that an industrial furnace heat storage body comprising sidewall oriented topology structures according to the present utility model achieves at least the following beneficial effects: [0038] Thanks to the provision of the industrial furnace heat storage body comprising sidewall oriented topology structures, under unchanged flame conditions of the combustion chamber, by expanding the actual reflective area of the industrial furnace inside wall for the thermal radiation rays, the efficiency of reflection of the flame thermal radiation by the inside wall of the combustion chamber of the industrial furnace is raised, so that, after the flame thermal radiation rays from the interior of the furnace combustion chamber have reached the surface of this heat storage body comprising sidewall oriented topology structures, ample reflection takes place at the actual extended surface of the topological structures so that these reflected rays strike the workpiece or pipes and are consequently absorbed by the workpiece. Under the same thermal radiation environment, the use of a heat storage body having sidewall oriented topology structures for cladding the inside wall of an industrial furnace enables the actual extent of the overall surface area of the sidewall surface when the heat storage body main body has such oriented topology structures to greatly exceed, by at least five times, that which would be obtained from the contour projection surface of the sidewall surfaces without these oriented topology structures. Thus the inside wall of the combustion chamber provides a higher intensity of radiation and the reflection efficiency of the inside wall of the combustion chamber of the industrial furnace for thermal radiation is increased, raising the overall heat transfer efficiency of the industrial heating furnace and so achieving an energy saving and emission reduction effect.
