Description

Technical Field

[0001] The invention relates to the technical field of honeycomb ceramic carriers, and in particular to a cylindrical honeycomb carrier and a catalytic body. Background Art

[0002] In the prior art, a straight-through honeycomb carrier with a wide range of applications is in the shape of a cylinder. The compartments of the cylindrical straight-through honeycomb carrier generally have a square cross-sectional shape, and the square compartments are arranged in a checkerboard pattern in the cylindrical straight-through honeycomb carrier. However, in these square compartments, when the outer wall of the carrier is impacted by external force, one of the outward-facing vertices in a group of diagonals whose diagonal direction is perpendicular or nearly perpendicular to the outer circumferential surface of the cylindrical carrier can be regarded as consisting of two components when the external force is transmitted inside the carrier: a "radial force" pointing to the inside of the carrier along the radial direction and a "circumferential force" along the circumferential direction of the cross section. Among them, the radial force is often a stronger component. When the radial force passes through the vertices, the right-angled vertices may cause deformation or even damage to the square compartment when bearing the radial force. Therefore, the right-angled vertices in this orientation become the weak link of the cylindrical straight-through carrier in the shape of a square compartment; when the diagonal direction of the right-angled vertices completely coincides with the radial direction of the cross section, the defect of the above-mentioned weak area is more obvious; therefore, the short-board effect leads to a reduction in the strength and pressure-bearing capacity of the entire cylindrical straight-through honeycomb carrier. In addition, the cracking at a forty-five-degree angle on the cross section of the honeycomb carrier, that is, the cracking in the diagonal direction, is not only affected by external forces. When the heating speed itself is too fast, the stress of the expansion of the honeycomb carrier will also be loaded onto the compartment walls in the form of radial force.

[0003] Therefore, when the cylindrical straight-through honeycomb carrier is impacted by external force and the external force is transmitted inside the carrier, especially when the radial component of the external force passes through the outward right-angled vertices, the square compartments may be deformed or even damaged. The internal expansion stress generated by the rapid heating of the honeycomb carrier may affect the compartment walls and cause damage. These problems have become urgent issues to be solved in this field. Summary of the invention

[0004] The purpose of the present invention is to provide a cylindrical honeycomb carrier and catalyst to solve the problem that when the cylindrical straight-through honeycomb carrier is impacted by external force, the external force is transmitted inside the carrier, especially the radial component of the external force passes through the outward right-angled vertices, which may cause the square compartments to deform or even break.

[0058] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present invention. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0059] It should be noted that the "reinforced area" in the specification of the present invention refers to the area where the strength enhancement design is made for the compartment strength, and the "non-reinforced area" refers to the area where the strength enhancement design is not made for the compartment strength.

[0060] In addition, the "square compartment" in the present specification specifically includes a compartment with a square cross-section and a compartment with a rectangular cross-section.

[0061] First aspect

[0062] See also Figure 1 , Figure 4 , Figure 7 , Fig.10 , Fig.13 The present invention provides a cylindrical honeycomb carrier, wherein a reinforcement area and a non-reinforcement area 3 are distributed in the cross section of the honeycomb carrier; wherein the reinforcement area is located at the peripheral position in the cross section of the honeycomb carrier; the number of the reinforcement areas is at least two; the reinforcement area includes a thickening area 1, and the wall thickness of the compartment in the thickening area 1 is greater than the wall thickness of the compartment in the non-reinforcement area 3. It is worth noting that thickening the wall thickness in the crack-prone area improves the strength of the square format, helps to reduce the influence of radial force, and reduces the deformation or even damage of the square compartment.

[0063] As mentioned in the previous background technology, in a square compartment, one of the outward-facing vertices in a group of diagonals whose diagonal direction is perpendicular or nearly perpendicular to the outer circumferential surface of the cylindrical carrier, when the outer wall of the carrier is impacted by external force, the force can be regarded as consisting of two components when it is transmitted inside the carrier, namely, a "radial force" pointing to the inside of the carrier along the radial direction and a "circumferential force" along the circumferential direction of the cross section. Among them, in most application scenarios, the radial force is often a stronger component. When the radial force passes through the vertices, the right-angled vertices may cause the square compartment to deform or even break when bearing the radial force. Therefore, the right-angled vertices in this position become the weak link of the cylindrical straight-through carrier in the shape of a square compartment; wherein, when the diagonal direction of the right-angled vertices completely coincides with the radial direction of the cross section, the defects of the above-mentioned weak area are more obvious; therefore, the short-board effect leads to a reduction in the strength and pressure-bearing capacity of the entire cylindrical straight-through honeycomb carrier. Therefore, the present invention proposes the above solution, by setting a reinforcement zone and thickening the partition wall thickness of the compartment in the reinforcement zone, thereby enhancing the compressive strength and impact resistance of the partition wall and the compartment. In addition, on the cross section of the honeycomb carrier, the 45-degree cracking, that is, the diagonal cracking, is not only affected by external forces. When the heating speed of the honeycomb carrier is too fast, the stress of the expansion of the honeycomb carrier will also be loaded on the partition wall in the form of radial force. The above technical solution provided by the present invention can also solve the problem that "the internal thermal stress generated by the excessively fast heating speed will cause damage to the partition wall".

[0064] It is worth noting that the above-mentioned thickened partition wall concept provided by the present invention can be applied not only to the scenario of "cylindrical carrier + square compartment", but also to other carriers that are also designed as square or rectangular compartments but have other three-dimensional shapes, such as honeycomb carriers with elliptical cross-sections or various polyhedral prisms such as triangular prisms, quadrangular prisms, pentagonal prisms, hexagonal prisms, and octagonal prisms; because when these honeycomb carriers are designed to have square or rectangular compartments, the right-angled vertices in the compartments that are opposite to the center of the carrier cross section and facing the outer surface of the carrier will also directly face the radial component with greater force that is impacted by external forces. In other words, the inventive concept of thickening the compartment wall provided by the present invention has good versatility.

[0065] In some embodiments of the present invention, the wall thickness of the compartment in the thickened area 1 is 1.5 to 2.8 times the wall thickness of the compartment in the non-reinforced area 3, and can be any one of 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7 times, or any value within a range of values ​​consisting of any two values, which can be selected and adjusted according to actual application scenarios and design standards. Figure 1 , Figure 4 , Figure 7 , Fig.10 , Fig.13 In some embodiments of the present invention, along the radial direction of the cross section of the honeycomb carrier, from the center of the cross section of the honeycomb carrier to the outer peripheral surface of the honeycomb carrier, the wall thickness of the compartment in the thickening zone 1 gradually increases. It is worth noting that in these embodiments, the average thickness of the wall thickness of the compartment in the thickening zone 1 is 1.5 to 2.8 times the wall thickness of the compartment in the non-reinforced zone 3, and can be any one of 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7 times or any value in the range of values ​​composed of any two values, which can be selected and adjusted according to the actual application scenario and design standards; or, in these embodiments, the minimum thickness of the wall thickness of the compartment in the thickening zone 1 is at least 1.5 times the wall thickness of the compartment in the non-reinforced zone 3, and the maximum thickness is at most 2.8 times the wall thickness of the compartment in the non-reinforced zone 3. It is worth noting that thicker wall thickness will lead to higher stress between the thickened area 1 and the non-reinforced area 3. When internal stress is generated by external force or thermal expansion, the honeycomb ceramic is more likely to break at the junction of the thickened area 1 and the non-reinforced area 3, while thinner wall thickness will lead to insufficient support and easy breakage.

[0066] See also Figure 1 , Figure 4 , Figure 7 , Fig.10 , Fig.13 In some embodiments of the present invention, the at least two reinforcement areas are centrally symmetrical about the center of the honeycomb carrier. This makes it more convenient to make a mold and can completely include the crack-prone area.

[0067] In some embodiments of the present invention, the cells of the thickened region 1 include square cells, and some of the square cells are arranged in a manner that the diagonal lines coincide with the radial lines of the honeycomb carrier.

[0068] In some embodiments of the present invention, a diagonal wall is provided in the partial square compartment, and the diagonal wall is arranged along the radial direction. It is worth noting that the diagonal wall structure is equivalent to isolating a square compartment into two triangular compartments. Since the triangle has good structural stability and pressure bearing capacity, this solution can further improve the impact resistance and pressure bearing resistance of the honeycomb carrier.

[0069] See also Figure 1 , Figure 4 , Figure 7 , Fig.10 , Fig.13 In some embodiments of the present invention, the reinforcement area further includes a special-shaped compartment area 2; the cross-sectional shape of the compartment in the special-shaped compartment area 2 has a chamfer and / or an inner convex portion.

[0070] See also Figure 4-Figure 5 , Figure 7-Figure 8 , Figure 10-11 , Figure 13-14 In some embodiments of the present invention, the shape of the inner convex portion is an inner convex right angle, an inner convex rounded corner or an inner convex flower angle, and the inner convex right angle, inner convex rounded corner or inner convex flower angle are all configured to protrude inward relative to the interior of the compartment in which it is located.

[0071] See also Figures 10 to 15 In some embodiments of the present invention, the thickened area 1 is arranged around the periphery of the special-shaped compartment area 2.

[0072] See also Figures 4 to 9 In some embodiments of the present invention, the special-shaped compartment area 2 is arranged around the periphery of the thickened area 1.

[0073] In some embodiments of the present invention, the thickened area 1 and the special-shaped compartment area 2 are separated by the non-reinforced area 3 .

[0074] See also Figure 4 and Figure 7 In some embodiments of the present invention, the number of the reinforcement zones is four, each of which has a thickening zone 1 and a special-shaped compartment zone 2 surrounding the thickening zone 1; each thickening zone 1 has a partial square compartment, and each special-shaped compartment zone 2 is respectively surrounded by the corresponding thickening zone 1. The existence of the special-shaped compartment zone further transitions, and when the special-shaped transition zone is between the thickening zone and the ordinary compartment, it can buffer the stress between the thermal expansion of the two, making the honeycomb ceramic structure more stable.

[0075] See also Figure 4 and Figure 7 In some embodiments of the present invention, the cross-sectional shape of each reinforcement area is a fan ring, the central angle of the fan ring ranges from 50° to 80°, and the ratio of the radial dimension of the fan ring in the cross section of the honeycomb carrier to the radius of the cross section of the honeycomb carrier is (0.2-0.35): 1. The smaller fan ring area controls its angle and ring radius, so that the opening rate of the honeycomb ceramic end face changes less and the back pressure increase is smaller.

[0076] See also Figure 4 and Figure 7 In some embodiments of the present invention, the cross-sectional shape of each of the thickened areas 1 is a fan-shaped ring, the central angle of the fan-shaped ring is in the range of 20° to 40°, and the ratio of the radial dimension of the fan-shaped ring in the cross-section of the honeycomb carrier to the radius of the cross-section of the honeycomb carrier is (0.05 to 0.15):1.

[0077] See also Figure 4and Figure 7 In some embodiments of the present invention, each reinforcement zone is provided with a thickening zone 1 and a special-shaped compartment zone 2 surrounding the thickening zone 1, the reinforcement zone is radially symmetrical with respect to the cross-section of the carrier, the thickening zone is radially symmetrical with respect to the cross-section of the carrier, and the special-shaped compartment zone is radially symmetrical with respect to the cross-section of the carrier.

The reinforcement zone is symmetrical about the reference line P, the thickening zone is symmetrical about the reference line P, and the special-shaped compartment zone is symmetrical about the reference line P.

[0079] See also Fig.10 and Fig.13 In some embodiments of the present invention, the number of the reinforcement zones is four, each of the reinforcement zones has one of the special-shaped compartment zones 2 and a thickening zone 1 surrounding the periphery of the special-shaped compartment zone 2; each of the special-shaped compartment zones 2 has the partial square compartment, and each of the thickening zones 1 is respectively surrounded by the periphery of the special-shaped compartment zone 2 corresponding thereto.

[0080] See also Fig.10 and Fig.13 In some embodiments of the present invention, the cross-sectional shape of each reinforcement zone is a fan-shaped ring, the central angle of the fan-shaped ring is in the range of 50° to 80°, and the ratio of the radial dimension of the fan-shaped ring in the cross-section of the honeycomb carrier to the radius of the cross-section of the honeycomb carrier is (0.2 to 0.35):1.

[0081] See also Fig.10 and Fig.13 In some embodiments of the present invention, the cross-sectional shape of each of the special-shaped compartment areas 2 is a fan-shaped ring, the central angle of the fan-shaped ring is in the range of 20° to 40°, and the ratio of the radial dimension of the fan-shaped ring in the cross-section of the honeycomb carrier to the radius of the cross-section of the honeycomb carrier is (0.05 to 0.15):1.

[0082] See also Fig.10 and Fig.13 In some embodiments of the present invention, each reinforcement zone is provided with a thickening zone and a special-shaped compartment zone 2 surrounding the thickening zone, the reinforcement zone is radially symmetrical with respect to the cross-section of the carrier, the thickening zone is radially symmetrical with respect to the cross-section of the carrier, and the special-shaped compartment zone is radially symmetrical with respect to the cross-section of the carrier.

[0083] See also Fig.10 and Fig.13In some embodiments of the present invention, the reinforcement zone has a reference line P, which coincides with a diagonal line of several square compartments and coincides with the radial direction of the cross section of the carrier. The reinforcement zone is symmetrical about the reference line P, the thickening zone is symmetrical about the reference line P, and the special-shaped compartment zone is symmetrical about the reference line P.

[0084] See also Figures 1 to 3 The present invention provides a honeycomb carrier, the compartments of the honeycomb carrier are square, and a reinforcement area and a non-reinforcement area 3 are provided in the cross section of the carrier. The square compartments in the non-reinforcement area 3 can be regarded as conventional square compartments in the prior art, while the compartments in the reinforcement area adopt a wall thickening design, that is, the carrier provided in this embodiment is provided with a thickening area 1, and the wall thickness of the compartments in the thickening area 1 is greater than the wall thickness of the compartments in the non-reinforcement area 3, and the specific thickening multiple can be any value in the range of 1.5 to 2.8 times. The number of thickening areas 1 of the carrier provided in this embodiment is four, and the four thickening areas 1 are centrally symmetrically distributed about the center of the cross section of the cylindrical carrier, and the four thickening areas 1 are located in the peripheral area of ​​the carrier cross section; and the four thickening areas 1 just include the "square compartments whose diagonal direction coincides or nearly coincides with the radial direction of the carrier cross section", because the compressive strength of the compartments in this distribution mode is relatively the most fragile, so the carrier provided by this embodiment of the present invention can enhance the compressive resistance of these compartments, thereby improving the overall compressive resistance of the carrier. It is worth mentioning that the concept of the reinforcement area provided by the present invention can be regarded as "at least two 'reinforcement ribs' or 'strengthening ribs' are set along the longitudinal direction of the cylindrical carrier" to "reinforce and strengthen" the pressure-bearing weak area of ​​the carrier. Furthermore, the central angle of the thickening area 1 in the form of a fan ring is 30°, and the length ratio of the radial dimension of the fan ring to the radius of the carrier cross section is 0.15:1; the mesh number specification of the compartment density is 750 mesh.

[0085] See again Figures 1 to 3 The present invention also provides a honeycomb carrier, which, based on the aforementioned design concept of only the thickening zone 1, further integrates the concept of "gradual wall thickness design", that is: while setting the thickening zone 1, the wall thickness of the compartment in the thickening zone 1 is gradually thickened from the center of the carrier cross section to the outer wall of the carrier along the radial direction of the carrier cross section; at this time, the average wall thickness in each thickening zone 1 (the sum of the thickness of the thickest and thinnest parts of the wall thickness in the thickening zone 1 divided by two) can be any value between 1.5 and 2.8 times the wall thickness of the compartment in the non-reinforced zone 3; of course, the thickness at the thinnest part can also be at least 1.5 times the wall thickness of the compartment in the non-reinforced zone 3, and the thickness at the thickest part can be at most 2.8 times the wall thickness of the compartment in the non-reinforced zone 3.

Furthermore, the central angle of the thickening area 1 in the form of a fan ring is 30°, and the length ratio of the radial dimension of the fan ring to the radius of the carrier cross section is 0.15:1; the mesh number specification of the compartment density is 750 meshes.

[0089] See also Figures 13 to 15The present invention provides a honeycomb carrier, wherein the cross section of the carrier is distributed with two types of reinforcement areas, namely, a thickening area 1 and a special-shaped compartment area 2, wherein one set of diagonals in the compartment within the special-shaped compartment area 2 is an inward convex fillet, and the other set of diagonals in the same compartment is a right angle; in this scheme, there are a total of four thickening areas 1 and four special-shaped compartment areas 2, and each thickening area 1 is respectively arranged around the periphery of a special-shaped compartment area 2; this scheme is equivalent to integrating the two reinforcement concepts and applying them to the same honeycomb carrier to further enhance the strength of the honeycomb carrier. Furthermore, the central angle of the thickening area 1 in the form of a fan ring is 30°, and the length ratio of the radial dimension of the fan ring to the radius of the carrier cross section is 0.15:1; the mesh number specification of the compartment density is 750 meshes.

[0090] See also Fig.16 The present invention shows a honeycomb carrier of the prior art, which is also cylindrical and has square compartments arranged in a checkerboard pattern. However, the thickening area 1 of the carrier is arranged in a full circle outside the cross section of the carrier, and the ratio of the radial dimension of the annular area to the radius of the cross section of the carrier is 0.15:1, and the mesh number specification of the cell density is 750 meshes. In this honeycomb carrier of the prior art, there is no "thickness transition zone" between the thickening area 1 and the non-reinforced area 3, so the stress on the partition wall will have a sudden change, and the sudden change in wall thickness in the structure will make the extrusion speed uneven during the processing. During extrusion molding, the processing mold needs to be adjusted several times to successfully extrude the rough blank of the entire carrier; in addition, the area of ​​the thickening area 1 of this honeycomb carrier accounts for a large proportion, but the area that actually needs to be reinforced is not so large, so there will be a certain degree of waste of raw materials.

[0091] See also Fig.17 The present invention shows a honeycomb carrier of the prior art, which is also cylindrical in shape and has square compartments arranged in a checkerboard pattern. However, the thickening area 1 of the carrier is of fan-shaped design. The fan-shaped thickening area 1 extends from the outer wall of the carrier to the central area of ​​the carrier cross section. The central angle of the fan-shaped area is 30°, and the mesh number specification of the compartment density is 750 mesh. This kind of honeycomb carrier of the prior art does not have a "thickness transition zone" between the thickening area 1 and the non-reinforced area 3, so the stress on the partition wall will have a sudden change, and the sudden change in wall thickness in the structure will lead to uneven extrusion speed during processing. Conventional means cannot be used to adjust the extrusion speed between the compartments of the thickening area 1 and the compartments of the non-reinforced area 3 to be the same during the extrusion molding process; in addition, compared with Figures 1 to 3 Compared with the honeycomb carrier shown and provided by the present invention, the thickened region 1 of the honeycomb carrier of the prior art has a larger area proportion, but the area actually requiring reinforcement is not so large, so there will be a certain degree of waste of raw materials.
