Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection materials, in particular to a honeycomb ceramic heat storage body. Background Art

[0002] Honeycomb ceramic thermal storage body is a new type of energy-saving and environmentally friendly heat medium. It can store heat by absorbing thermal energy and then release the stored heat energy to improve thermal efficiency. Its principle is mainly to use the high specific surface area and porosity of honeycomb ceramics to store heat energy in the pores inside the ceramics, and store and supply heat at different stages. Honeycomb ceramic thermal storage body is widely used in the fields of industrial energy-saving technology and environmental protection technology. It is an effective way to improve the thermal utilization efficiency of thermal equipment and reduce equipment energy consumption. It is also an important means to solve energy and environmental problems.

[0003] The existing honeycomb ceramic thermal storage body has the advantages of large specific surface area, small pressure drop, good thermal conductivity, and good resistance to thermal shock. The internal parallel straight channel structure reduces the resistance of air flow through the pores, thereby improving the single-pore volume heat transfer efficiency of the thermal storage body. However, during the heating stage, this regular and uniform unidirectional channel structure cannot quickly diffuse horizontally to the surrounding areas when the exhaust gas enters the thermal storage body, so that most of the airflow is concentrated in the center of the thermal storage body. The heat exchange between the airflow and the thermal storage body is uneven in the center and around the bed, which seriously affects the heat exchange efficiency of the equipment and the temperature uniformity of the bed, and then affects the heat storage efficiency and quality as well as the normal use of the equipment placed in the thermal storage body. For this reason, we propose a honeycomb ceramic thermal storage body. Utility Model Content

[0005] The purpose of the utility model is to provide a honeycomb ceramic heat storage body to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a honeycomb ceramic heat storage body, comprising a main body, a docking groove is provided at the bottom end of the main body, and a heat storage group is arranged inside the main body, the heat storage group comprises a heat storage cavity, and straight-row channels are distributed inside the heat storage cavity, arc-shaped openings are provided at both ends of the straight-row channels, a heat storage channel is provided on one side of the straight-row channels, and drainage holes are distributed around the heat storage channel, and the drainage holes extend in an inclined state.

[0007] Furthermore, the drainage holes are arranged in a forked shape around the heat storage channel, and the drainage holes are connected to the heat storage channel and the straight discharge channel.

[0008] Furthermore, the straight-row pores and the heat storage pores are arranged equidistantly along the inside of the heat storage chamber, and the heat storage chamber and the main body are integrally fixedly connected.

[0010] Furthermore, the docking holes are evenly distributed along the outer walls of the ceramic body, and the drainage holes are communicated with the docking holes.

[0011] Furthermore, the docking groove includes a base, and a frame groove is opened on the inner wall of the base. The base and the ceramic body are fixedly connected as one body, and the position of the base is aligned with the position of the tenon frame at the top of the ceramic body.

[0012] Furthermore, the inner wall size around the frame groove matches the outer wall size around the tenon frame, and the frame groove is opened in a frame shape along the inner wall around the base.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

Through the bifurcated structure discharge holes distributed around the heat storage channels, the downstream gas is diffused and transferred along the discharge holes. With the connection of the straight channels, this heat storage body avoids the heat storage process in a single area, which causes waste, and improves the heat storage range and efficiency.

[0015] When the ceramic heat storage body is used and stacked, its outer wall is butted against the outer wall, and can be connected through the butt holes and internal discharge holes on the outer walls of the ceramic body, so that the discharged gas at a single position can evenly penetrate each other through the butt holes, thereby increasing the gas passing range and coverage, and increasing the conduction range and stable uniformity;

[0016] When the ceramic heat storage bodies are used in combination with each other, they can be stacked up by means of the tenon frame at the top of the ceramic body and the frame groove at the bottom of another group of ceramic bodies, thereby maintaining accurate combination alignment, making the holes aligned neatly during use, and improving the stability of gas transport and diffusion.

[0026] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] The utility model provides Figure 1-4 A honeycomb ceramic heat storage body shown includes a main body 1, a docking groove 2 is provided at the bottom end of the main body 1, and a heat storage group 3 is arranged inside the main body 1, the main body 1 includes a ceramic body 101, and a tenon frame 102 is connected to the top of the ceramic body 101, a docking groove 2 is provided at the bottom end of the ceramic body 101, and docking holes 103 are distributed on the outer walls around the ceramic body 101;

[0028] In order to improve the stable conduction of gas and heat during the assembly process, Figure 1As shown, when this ceramic heat storage body is in use and stacked, its outer wall is connected to the outer wall, and can be connected through the docking holes 103 opened on the outer walls around the ceramic body 101 and the internal discharge holes 305, so that the discharged gas at a single position can evenly penetrate each other through the docking holes 103, thereby increasing the gas passing range and coverage rate, and increasing the conduction range and stable uniformity.

[0029] like Figure 2 As shown, the docking slot 2 includes a base 201, and a frame groove 202 is opened on the inner wall of the base 201. The base 201 and the ceramic body 101 are integrally fixedly connected, and the position of the base 201 is aligned with the position of the tenon frame 102 at the top of the ceramic body 101;

[0030] In order to improve the stability and hole alignment of the ceramic heat storage body when using the combination, such as Figure 1-2 As shown, when the ceramic heat storage bodies are used in combination with each other, they can be stacked up by means of the tenon frame 102 at the top of the ceramic body 101 and the frame groove 202 at the bottom of another group of ceramic bodies 101, thereby maintaining precise combination alignment, making the holes aligned neatly during use, and improving the stability of gas transport and diffusion.

[0031] like Figure 3-4 As shown, the heat storage group 3 includes a heat storage chamber 301, and a straight discharge channel 302 is distributed inside the heat storage chamber 301, and arc-shaped openings 303 are provided at both ends of the straight discharge channel 302. A heat storage channel 304 is provided on one side of the straight discharge channel 302, and drainage holes 305 are distributed around the heat storage channel 304, and the drainage holes 305 extend in an inclined shape;

[0032] Finally, in order to effectively improve the overall gas and heat conduction efficiency and range, such as Figure 3-4 As shown, this ceramic heat storage body absorbs and conducts the heat of the gas by distributing multiple groups of straight channels 302 and heat storage channels 304 that are equidistantly arranged and intersecting with each other in the internal heat storage chamber 301.
