Description

Technical Field

[0001] This utility model relates to the field of ceramic heat storage technology, and in particular to a novel honeycomb ceramic heat storage body. Background Technology

[0002] Honeycomb ceramic regenerators are a type of high-efficiency, energy-saving, and environmentally friendly material. In regenerative combustion systems, they absorb heat from exhaust gases and release it during combustion, increasing combustion temperature and thus improving energy efficiency and reducing energy consumption. However, traditional honeycomb ceramic regenerators, with their single-cell closed design, have poor thermal shock resistance. Under temperature fluctuations during heat storage and release, traditional regenerators are prone to cracking due to thermal expansion and contraction. Utility Model Content

[0003] The purpose of this invention is to provide a novel honeycomb ceramic heat storage body that can achieve thermal shock resistance without any shortcomings, and solve the problem of traditional heat storage materials being prone to cracking due to thermal expansion and contraction.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel honeycomb ceramic heat storage body, comprising a heat storage unit, wherein the heat storage unit comprises a horizontal plate, a vertical plate and a frame, the horizontal plate and the vertical plate intersect horizontally and vertically within the frame, and multiple cells are formed between the horizontal plate and the vertical plate and between the horizontal plate and the frame, the cells are provided with multiple columns, the upper part of the cells in the odd-numbered columns is provided with an upper partition, and the lower part of the cells in the even-numbered columns is provided with a lower partition.

[0005] Furthermore, the distance between the bottom of the upper partition and the cell and the distance between the top of the lower partition and the cell are both 0.7-2mm.

[0006] Furthermore, the heat storage unit is provided in multiple sets. A first extended partition is provided on the outside of the frame, which is arranged in the same manner as the upper partition and the lower partition. A first vertical extended plate is provided at the bottom of the frame, which is opposite to the position of the vertical plate. A second vertical extended plate is provided at both ends of the bottom of the frame. A first snap-fit ​​protrusion is provided at the end of both the first and second vertical extended plates. A first snap-fit ​​groove is provided at the upper end of the frame to engage with the snap-fit ​​protrusion. The multiple sets of heat storage units are arranged vertically, and the first snap-fit ​​protrusion on the upper heat storage unit engages with the first snap-fit ​​groove on the lower heat storage unit.

[0007] Furthermore, the heat storage unit is provided in multiple sets. A first horizontal extension plate is provided on the left side of the frame, opposite to the horizontal plate. Second horizontal extension plates are provided at both ends of the left side of the frame. The ends of the first and second horizontal extension plates are provided with second snap-fit ​​protrusions. A second snap-fit ​​groove is provided on the right side of the frame to engage with the second snap-fit ​​protrusions. The multiple sets of heat storage units are arranged left and right. The second snap-fit ​​protrusion on the heat storage unit on the left engages with the second snap-fit ​​groove on the heat storage unit below it. When the rightmost cell in the frame is provided with an upper partition, the lower surfaces of the first horizontal extension plate and the upper second horizontal extension plate are provided with second extension partitions arranged in the same manner as the lower partition. When the rightmost cell in the frame is provided with a lower partition, the upper surfaces of the first horizontal extension plate and the lower second horizontal extension plate are provided with third extension partitions arranged in the same manner as the upper partition.

[0008] Furthermore, the heat storage unit is provided in multiple sets. A fourth extended partition, arranged in the same order as the upper and lower partitions, is provided outside the frame. A third vertical extension plate of the vertical plate is provided at the bottom of the frame. Fourth vertical extension plates are provided at both ends of the bottom of the frame. A third horizontal extension plate, positioned opposite the horizontal plate, is provided on the left side of the frame. Fourth horizontal extension plates are provided at both ends of the left side of the frame. Third engaging protrusions are provided at the ends of the third vertical extension plate, the fourth vertical extension plate, the third horizontal extension plate, and the fourth horizontal extension plate. The upper part and right side of the frame have openings that engage with the third engaging protrusions. The third snap-fit ​​groove is connected to the third snap-fit ​​groove on the heat storage unit. Multiple sets of heat storage units are arranged horizontally and vertically adjacent to each other. The third snap-fit ​​protrusion on the heat storage unit snaps into the third snap-fit ​​groove on the adjacent heat storage unit. When the rightmost cell in the frame is set as the upper partition, the lower surfaces of the third horizontal extension plate and the fourth horizontal extension plate at the upper end are both set with a fifth extension partition that is arranged in the same way as the lower partition. When the rightmost cell in the frame is set as the lower partition, the upper surfaces of the third horizontal extension plate and the fourth horizontal extension plate at the lower end are both set with a sixth extension partition that is arranged in the same way as the upper partition.

[0009] Furthermore, the thickness of the horizontal plate is 1.5-2mm; the thickness of the vertical plate is 1.4-1.9mm.

[0010] Furthermore, the thickness of the top and bottom sides of the frame is 1.7-1.8 mm, and the thickness of the left and right sides is 1.6-1.7 mm.

[0011] Furthermore, the length of the cell is 8-13mm and the width is 3.5-5mm.

[0012] Furthermore, the upper partition and the lower partition are 3mm long and 1.5-1.9mm wide.

[0013] The beneficial effects of this invention are as follows: The interlaced honeycomb-like through-holes formed by the upper and lower partitions geometrically increase the specific surface area, significantly increasing the contact area between the high-temperature fluid and the ceramic wall, and increasing the heat absorption and release rate by 3-5 times. Simultaneously, the through-holes allow direct heat convection, compressing the heat exchange time to 1 / 10 of traditional structures, achieving "second-level" heat storage and release cycles. The periodic structure of the upper and lower partitions disperses thermal stress, allowing them to withstand over 1000 cycles of temperature difference impacts during heat storage and release without damage, completely solving the problem of "easily cracking due to thermal expansion and contraction" in traditional heat storage materials. The array-style arrangement of the partitions and the thickened outer wall design increase the overall impact and compression resistance by 40%, making "zero damage" during transportation and installation the norm. The high-density partition arrangement increases the heat storage capacity per unit volume by 50%, and reduces the equipment footprint by 40%, directly reducing investment in factory infrastructure.

[0028] Please see Figures 1 to 5This utility model provides an embodiment: a novel honeycomb ceramic heat storage body, including a heat storage unit, the heat storage unit including a horizontal plate 1, a vertical plate 2 and a frame 3, the horizontal plate 1 and the vertical plate 2 intersect horizontally and vertically within the frame 3, a plurality of cells 4 are formed between the horizontal plate 1 and the vertical plate 2 and between the horizontal plate 1 and the vertical plate 2 and the frame 3, the cells 4 are provided with multiple columns, the upper part of the cells 4 in the odd-numbered columns is provided with an upper partition 5, and the lower part of the cells 4 in the even-numbered columns is provided with a lower partition 6. This novel honeycomb ceramic heat storage body can be integrally molded using existing production equipment. The frame 3 is formed by the staggered connection of horizontal plates 1 and vertical plates 2, creating uniformly distributed cell 4. The upper partition 5 and lower partition 6 are staggered in the vertical columns within the cell 4. The staggered honeycomb-shaped through-holes formed by the upper and lower partitions 6 geometrically increase the specific surface area, significantly increasing the contact area between the high-temperature fluid and the ceramic wall, and increasing the heat absorption and release rate by 3-5 times. At the same time, the through-holes allow direct heat convection, compressing the heat exchange time to 1 / 10 of the traditional structure, achieving "second-level" heat storage and release cycles. The periodic structure of the upper and lower partitions 6 can disperse thermal stress, allowing it to withstand over 1000 cycles of temperature difference impact during the heat storage and release process without damage, completely solving the pain point of "easily cracked by thermal expansion and contraction" in traditional heat storage materials. The mechanical strength exceeds expectations: the array arrangement of the partitions and the thickened outer wall design increase the overall impact and compression resistance by 40%, making "zero damage" during transportation and installation the norm. Enhanced resistance to corrosive media such as sulfur, chlorine, and HF in industrial waste gases ensures stable operation even under harsh conditions, extending service life to 2-3 times that of traditional materials while reducing costs. The smooth channels formed by the upper and lower baffles 6 and cell 4 reduce ash adhesion by 60%, significantly minimizing downtime and maintenance due to blockages, making it particularly suitable for industrial environments prone to ash accumulation, such as RTO furnaces. The high-density baffle arrangement increases heat storage per unit volume by 50% and reduces the equipment footprint by 40%, directly lowering plant infrastructure investment.
