Description

Technical Field

[0001] This utility model relates to the field of heat storage ceramics technology, and in particular to a heat storage ceramic with catalytic properties. Background Technology

[0002] Thermal storage ceramics are ceramic materials with high-temperature heat storage capabilities, primarily used to store and release high-temperature thermal energy to improve energy utilization efficiency. They combine the excellent properties of ceramic materials, such as high-temperature resistance, corrosion resistance, and mechanical strength, and are commonly used in various high-temperature thermal energy applications. Thermal storage ceramics increase surface area and improve heat exchange efficiency through their porous structure; however, most existing thermal storage ceramics still have problems that need to be solved.

[0003] Most existing heat storage ceramics do not have catalytic functions; they can only store and release heat energy and cannot actively participate in the transformation or reaction of pollutants. Special catalyst devices need to be installed at the downstream or upstream stages, increasing equipment size and maintenance costs. If harmful substances in the exhaust gas (such as NOx, VOC, and CO) are not reduced through catalytic transformation under high-temperature conditions, it may be difficult to meet environmental standards. Therefore, it is necessary to design a heat storage ceramic with catalytic properties to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heat storage ceramic with catalytic properties.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A catalytically active heat storage ceramic includes a first heat storage ceramic and a second heat storage ceramic. Both the first and second heat storage ceramics have mounting grooves on their adjacent sides. A storage box is disposed between the first and second heat storage ceramics, and the storage box is adapted to fit the two mounting grooves. Mesh plates are fixedly connected to the inner walls of the top and bottom ends of the storage box. A catalyst is disposed inside the storage box. Slots are formed on both sides of the storage box. Locking blocks are fixedly connected to the inner walls of both sides of the first and second heat storage ceramics at their adjacent ends, and the locking blocks are adapted to fit the slots. Two nuts are embedded on both sides of the storage box. A threaded cylinder is provided on one side of each nut, and a bolt is disposed inside the threaded cylinder. The bolt is adapted to fit the threaded cylinder and the nut. Due to the use of… The first and second heat storage ceramics are equipped with storage boxes, and catalysts are placed in the storage boxes to catalyze the waste gas. Therefore, by using the catalyst in the storage box at high temperature to purify waste gas such as VOCs and NOx and control emissions, the heat storage and catalytic functions are combined to achieve efficient conversion of pollutants and energy recovery. This effectively solves the problem mentioned in the background technology that most existing heat storage ceramics do not have catalytic functions, can only store and release heat energy, and cannot actively participate in the conversion or reaction of pollutants. They also require the installation of special catalyst devices at the upstream or downstream. This technology combines the high-temperature heat storage characteristics of heat storage ceramics to enable catalytic reactions to proceed efficiently within an ideal temperature range, improve the conversion efficiency of pollutants, effectively control emissions, and help meet stricter environmental standards.

[0007] As a further embodiment of this utility model, a spiral groove is provided at the bottom of the first heat storage ceramic, and a spiral plate is provided in the spiral groove. The spiral plate and the spiral groove are adapted to each other, and the spiral plate is fixedly connected to the top of the second heat storage ceramic.

[0008] As a further embodiment of this utility model, two first slots are provided on both sides of the storage box, and the nut is disposed in the first slot, the first slot being adapted to the nut.

[0009] As a further embodiment of this utility model, both the first and second heat storage ceramics are provided with two second slots and two third slots, and the threaded cylinder is disposed in the second slot, and the threaded cylinder is adapted to the second slot.

[0010] As a further embodiment of this utility model, the nut is used to fix the storage box.

[0011] As a further embodiment of this utility model, the threaded cylinder is fixedly connected to the first heat storage ceramic and the second heat storage ceramic.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention employs a technique that uses storage boxes within the first and second heat storage ceramics, and catalysts within these boxes to catalyze the exhaust gas. This allows for the purification of exhaust gases (e.g., VOCs, NOx) and emission control through the high-temperature operation of the catalyst within the storage boxes. Combining heat storage and catalysis, it achieves efficient conversion of pollutants and energy recovery. This effectively solves the problem presented in the background art where most existing heat storage ceramics lack catalytic functionality, only storing and releasing heat energy without actively participating in pollutant conversion or reaction, requiring the installation of specialized catalyst devices at the upstream or downstream stages. This invention leverages the high-temperature heat storage characteristics of the heat storage ceramics to enable efficient catalytic reactions within an ideal temperature range, improving pollutant conversion efficiency, effectively controlling emissions, and helping to meet stricter environmental standards.

[0022] Reference Figure 1 - Figure 5 A catalytically active heat storage ceramic includes a first heat storage ceramic 1 and a second heat storage ceramic 2. Both the first and second heat storage ceramics 1 and 2 have mounting grooves 15 on their adjacent sides. A storage box 3 is disposed between the first and second heat storage ceramics 1 and 2, and the storage box 3 is adapted to the two mounting grooves 15. Mesh plates 4 are fixedly connected to the inner walls of the top and bottom ends of the storage box 3. A catalyst is disposed inside the storage box 3. Slots 5 are provided on both sides of the storage box 3. Locking blocks 6 are fixedly connected to the inner walls of both sides of the first and second heat storage ceramics 1 and 2 at their adjacent ends, and the locking blocks 6 are adapted to the locking slots 5. Two nuts 9 are embedded on both sides of the storage box 3. A threaded cylinder 10 is provided on one side of each nut 9, and a bolt 11 is disposed inside the threaded cylinder 10. The bolt 11 is adapted to the threaded cylinder 10 and the nuts 9. This technology, by employing storage boxes within the first and second heat storage ceramics and placing catalysts within these boxes to catalyze the exhaust gas, achieves efficient conversion of pollutants and energy recovery through the high-temperature purification of exhaust gases such as VOCs and NOx by the catalysts within the storage boxes. This effectively addresses the problem presented in the background technology that most existing heat storage ceramics lack catalytic functionality, only storing and releasing heat energy without actively participating in the conversion or reaction of pollutants, necessitating the installation of dedicated catalyst devices at the upstream or downstream stages. Furthermore, by combining the high-temperature heat storage characteristics of the heat storage ceramics, the catalytic reaction proceeds efficiently within an ideal temperature range, improving pollutant conversion efficiency, effectively controlling emissions, and helping to meet stricter environmental standards.

[0023] In this embodiment, a spiral groove 8 is provided at the bottom of the first heat storage ceramic 1, and a spiral plate 7 is provided in the spiral groove 8. The spiral plate 7 and the spiral groove 8 are adapted to each other. The spiral plate 7 is fixedly connected to the top of the second heat storage ceramic 2. During assembly, the first heat storage ceramic 1 is placed on the spiral plate 7, so that the position between the first heat storage ceramic 1 and the second heat storage ceramic 2 can be positioned.

[0024] In this embodiment, two first slots 12 are provided on both sides of the storage box 3, and the nut 9 is placed in the first slot 12, and the first slot 12 is adapted to the nut 9.

[0025] In this embodiment, both the first heat storage ceramic 1 and the second heat storage ceramic 2 have two second slots 13 and two third slots 14. The threaded cylinder 10 is disposed in the second slot 13 and is adapted to the second slot 13.

[0026] In this embodiment, nut 9 is used to fix the storage box 3.

[0027] In this embodiment, the threaded cylinder 10 is fixedly connected to the first heat storage ceramic 1 and the second heat storage ceramic 2.

[0028] Working Principle: During use, a large amount of high-temperature waste gas is preheated through the first heat storage ceramic 1 and the second heat storage ceramic 2, reducing energy consumption and improving overall energy utilization efficiency. The first and second heat storage ceramics 1 and 2 store and release energy, achieving continuous and stable heating and improving production efficiency. The catalyst in the storage box 3 purifies the waste gas at high temperatures, controlling emissions such as VOCs and NOx. Combining heat storage and catalysis functions, it achieves efficient conversion of pollutants and energy recovery. The catalyst in the storage box 3 is selected according to the actual application, such as copper oxide (CuO), manganese oxide (MnO2), and nickel oxide (NiO). During assembly, the storage box 3 is first placed in the mounting slot on the second heat storage ceramic 2. Within 15, the storage box 3 is positioned by the cooperation of the slot 5 and the block 6. Then, the first heat storage ceramic 1 is placed on the U-shaped plate 7, so that the U-shaped plate 7 is in the U-shaped groove 8, which can position the first heat storage ceramic 1 and the second heat storage ceramic 2. At this time, the threaded cylinder 10 and the nut 9 are coaxial. The bolt 11 is screwed into the threaded cylinder 10 and the bolt 11 is screwed into the nut 9. This restricts the position between the storage box 3 and the first heat storage ceramic 1 and the second heat storage ceramic 2, ensuring the stability between the storage box 3 and the first heat storage ceramic 1 and the second heat storage ceramic 2, and preventing the storage box 3 from separating from the first heat storage ceramic 1 and the second heat storage ceramic 2. The assembly is then complete, and the device can be used.
