Description

Technical Field

[0001] This utility model relates to the technical fields of catalyst carriers, heat storage ceramic balls, and chemical reaction tower support agents, specifically a three-dimensional open-cell honeycomb ceramic ball. Background Technology

[0002] In industrial applications such as heat storage, catalysis, fluid distribution, and as packing material or catalyst support in reaction towers, honeycomb ceramic balls are widely used due to their regularized flow channels and high specific surface area. Since flue gas in heat storage media flows in one direction only, and materials in catalytic reactions are transported in one direction only, the fluids are mostly unidirectional, leading to the predominantly unidirectional open-cell design of honeycomb ceramic balls.

[0003] Existing honeycomb ceramic balls feature a Z-axis unidirectional opening design, i.e., Z-axis pores. While structurally stable and less susceptible to damage from airflow impacts and thermal shocks, the Z-axis pore design leads to uneven heat flow distribution and localized temperature spikes in heat storage scenarios due to marginal effects, frequently causing ablation and damage to the heat storage body. Furthermore, in catalytic reactions, horizontal mass transfer is hindered, reactant diffusion is uneven, resulting in decreased product yield, quality fluctuations, and a significant increase in steam and energy consumption. Even in fluid filtration and adsorption processes, the Z-axis pores can cause flow field deviations, reducing separation efficiency and stability. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a three-dimensional perforated honeycomb ceramic ball to solve the technical problem in the background art that only Z-axis channels easily cause edge effects and dust accumulation.

[0005] The present invention provides a three-dimensional perforated honeycomb ceramic sphere, the three-dimensional perforated honeycomb ceramic sphere comprising: Ceramic ball body; The ceramic ball body has several evenly spaced through Z-axis channels. The ceramic ball body has X-dimensional through-holes and Y-dimensional through-holes in two dimensions perpendicular to the Z-axis channel. The surface of the ceramic ball body is provided with arc-shaped grooves.

[0006] Furthermore, the X-dimensional through-hole and the Y-dimensional through-hole are perpendicular to each other, and the number of the X-dimensional through-hole and the Y-dimensional through-hole is 1 to 6. The diameter of the X-dimensional through-hole and the Y-dimensional through-hole is 1 / 10 to 1 / 5 of the diameter of the three-dimensional open honeycomb ceramic ball.

[0007] Furthermore, the number of Z-dimensional through-holes is 3 to 50, and the diameter of the Z-dimensional through-holes is 1 / 30 to 1 / 5 of the diameter of the ceramic ball body, and they vertically penetrate the ceramic ball body from top to bottom.

[0008] Furthermore, the arc-shaped grooves are uniformly arranged along the circumference of the outer wall of the ceramic sphere, and the number of the arc-shaped grooves is 10 to 30.

[0009] Furthermore, the diameter of the arc-shaped groove is 1 / 10 to 1 / 5 of the diameter of the ceramic ball body.

[0010] Furthermore, the arc-shaped groove is hemispherical in shape.

[0011] Furthermore, the long side of the arc-shaped groove is parallel to the Z-dimensional through-hole, and the arc-shaped groove is located on the outer wall of the ceramic ball body.

[0012] Furthermore, both the X-dimensional through-hole and the Y-dimensional through-hole circumferentially penetrate the sidewall of the ceramic sphere body.

[0013] Furthermore, both the X-dimensional through-hole and the Y-dimensional through-hole are connected by inserting a pin or drilling a hole, and the ceramic ball body is prepared by plastic extrusion molding, dry extrusion molding, or plastic compression molding.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In the three-dimensional perforated honeycomb ceramic sphere of this invention, the ceramic sphere body has X-dimensional and Y-dimensional through-holes perpendicular to the Z-axis channels, and the horizontal channels construct a transverse low-resistance channel. The surface of the ceramic sphere body has arc-shaped grooves to guide fluid seepage with the curved surface. The two work together to break the vertical unidirectional flow constraint along the Z-axis, allowing the medium to mix fully in three-dimensional space, improving the uniformity of heat transfer, improving the diffusivity of reactants in the catalytic reaction, accelerating mass transfer, and reducing flow resistance and particle jamming through the permeable structure of the X-dimensional and Y-dimensional through-holes and arc-shaped grooves. This makes it easier for the fluid to flush away dust and reduce blockage, solving the technical problem in the prior art where only Z-axis channels can easily cause marginal effects and dust accumulation.

Detailed Implementation

[0016] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0017] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Please see Figures 1-4 The image shows a honeycomb ceramic ball according to one embodiment of the present invention. The honeycomb ceramic ball includes: 10 ceramic spheres; Furthermore, when the spherical ceramic spheres 10 are stacked, they form point contact. Compared to the surface contact of cubic / cylindrical spheres, the stacked layer has higher porosity and lower flow resistance of air / liquid.

[0020] In addition, the ceramic ball body 10 is formed by plastic extrusion, and then X-dimensional through-holes 30 and Y-dimensional through-holes 40 are opened by inserting a pin. It is then trimmed into a spherical shape. Alternatively, it can be dry-extruded into a ceramic ball body 10 containing Z-axis through-holes 20, and then X-dimensional through-holes 30 and Y-dimensional through-holes 40 are opened by drilling. Or it can be plastically pressed into a ceramic ball body 10 containing Z-axis through-holes 20, and then X-dimensional through-holes 30 and Y-dimensional through-holes 40 are opened by inserting a pin. Finally, it is dried and sintered to obtain the final product.

[0021] The ceramic ball 10 has several evenly spaced through Z-axis channels 20. The number of Z-axis channels 20 is 3 to 50, and the diameter of the Z-axis channels is 1 / 30 to 1 / 5 of the diameter of the ceramic ball body 10. The Z-axis channels 20 penetrate the ceramic ball body 10 vertically to achieve directional flow.

[0022] The ceramic ball body 10 has X-dimensional through-holes 30 and Y-dimensional through-holes 40 in two dimensions perpendicular to the Z-axis channel 20, forming a honeycomb ceramic ball with mutually perpendicular channels in all three dimensions. This allows the fluid to mix fully within the honeycomb ceramic ball, promoting more uniform and efficient mass and heat transfer, thereby changing the current situation of poor temperature uniformity and uneven mass transfer caused by only having Z-axis channels 20.

[0023] Preferably, the X-dimensional through-holes 30 and Y-dimensional through-holes 40 are perpendicular, and the number of X-dimensional through-holes 30 and Y-dimensional through-holes 40 is 1 to 6. The diameter of the X-dimensional through-holes 30 and Y-dimensional through-holes 40 is 1 / 10 to 1 / 5 of the diameter of the ceramic sphere body 10. This allows the material and heat (energy) to flow freely in all directions, resulting in a more balanced distribution of reactants and heat in the three directions.

[0024] As an example, not a limitation, the diameters of the X-dimensional through-hole 30 and the Y-dimensional through-hole 40 are larger than the diameter of the Z-axis through-hole 20. By increasing the transverse diameter, a low-resistance channel is formed in the horizontal direction, making it easier for the fluid to penetrate and diffuse in the transverse direction, and reducing the transverse accumulation of the fluid.

[0025] As an example, and not a limitation, the number of the X-dimensional through-hole 30 and the Y-dimensional through-hole 40 is 4, arranged in an equilateral triangle, and respectively located at the center point and three vertices.

[0026] The surface of the ceramic ball body 10 is provided with arc-shaped grooves 50 to reduce turbulent friction when the fluid flows through and reduce horizontal flow resistance.

[0027] It should be noted that the spherical ceramic ball body 10 and the hemispherical arc-shaped groove 50 ensure that the stacking process remains point contact. The arc-shaped groove 50 further widens the composite channel between the stacks and the groove flow channel, enhancing the fluid's penetration into the stacked layer, reducing particle jamming, and making it easier for the fluid to flush away dust / impurities. This greatly increases the pore area of ​​the stacked body, reduces the stacked weight, and significantly reduces the flow resistance of the stacked body to airflow or liquid flow, thereby reducing steam or air compressor consumption and making it easier for dust to be blown away rather than remaining in the stacked layer and blocking the channels. Therefore, it can be applied to a wider range of fields.

[0028] Preferably, the arc-shaped grooves 50 are uniformly arranged along the circumference of the outer wall of the ceramic ball body 10, and the number of arc-shaped grooves 50 is 10 to 30.

[0029] Furthermore, the diameter of the arc-shaped groove 50 is 1 / 10 to 1 / 5 of the diameter of the ceramic ball body 10, and the shape of the arc-shaped groove 50 is hemispherical, that is, the maximum depth of the arc-shaped groove 50 is half of its diameter.

[0030] Furthermore, the long side of the arc-shaped groove 50 is parallel to the Z-axis channel 20, and the arc-shaped groove 50 is provided on the outer side wall of the ceramic ball body 10.

[0031] Furthermore, both the X-dimensional through-hole 30 and the Y-dimensional through-hole 40 circumferentially penetrate the sidewall of the ceramic ball body 10.

[0032] In specific fields, the arrangement of X-dimensional through-holes 30 and Y-dimensional through-holes 40 will balance the reactant concentration, increase the specific surface area of ​​the catalyst, and improve the mass transfer efficiency of the catalytic reaction; create a more uniform temperature field for the regenerator, reducing the occurrence of local overheating that burns the regenerator and the inability to increase the heat storage rate; due to the two additional dimensional openings, the heat exchange area of ​​the regenerator is increased, improving the accumulation of waste heat from the flue gas and the energy recovery rate; reduce the bed resistance of the reaction tower, reducing steam consumption and energy consumption; and reduce or eliminate the problem of dust blockage in chemical reaction towers, especially coal chemical reaction towers and high-dust regenerators.

[0033] In summary, the three-dimensional perforated honeycomb ceramic sphere of this invention has at least the following beneficial effects: In the three-dimensional perforated honeycomb ceramic sphere provided by this utility model, the ceramic sphere body has X-dimensional through-holes and Y-dimensional through-holes in two dimensions perpendicular to the Z-axis channel, and the horizontal channels construct a transverse low-resistance channel; the surface of the ceramic sphere body has arc-shaped grooves to guide fluid seepage with the arc surface. The two work together to break the vertical unidirectional flow constraint, so that the medium is fully mixed in three-dimensional space, improves the uniformity of heat transfer, improves the diffusivity of reactants in catalytic reaction, and reduces flow resistance and particle jamming through the permeable structure of X-dimensional through-holes, Y-dimensional through-holes and arc-shaped grooves, making it easier for the fluid to flush away dust and reduce blockage. This solves the technical problem in the prior art that only Z-axis channels are prone to marginal effects and dust accumulation.
