[0035] The application provides a molecular sieve 1 which is convenient to assemble through structural design.
[0036] The molecular sieve 1 is a zeolite molecular sieve, and is particularly suitable for a natural gas and hydrogen co-production process, and is used for removing impurity gas in natural gas and hydrogen, and improving the purity and quality of products.
[0037] In combination Figures 1-3 The molecular sieve 1 comprises a molecular sieve body 11 and a connecting structure arranged on the side of the molecular sieve body 11. The molecular sieve body 11 is in a cuboid shape, and the molecular sieve body 11 has a plurality of honeycomb holes 111 which are penetrated along the height direction of the molecular sieve body 11. The connecting structure comprises a protruding strip 12 and a groove 13. The protruding strip 12 extends along the height direction of the molecular sieve body 11, the opening of the groove 13 is outward, and the groove 13 is penetrated along the height direction of the molecular sieve body 11. A plurality of protruding strips 12 are arranged on two adjacent side surfaces of the molecular sieve body 11, a plurality of grooves 13 are arranged on the remaining two side surfaces, and the protruding strips 12 and the grooves 13 are arranged correspondingly. The protruding strip 12 of one molecular sieve body 11 can be clamped in the groove 13 of another molecular sieve body 11 to realize the clamping connection between the two molecular sieve bodies 11.
[0038] Therefore, through the structure of the protruding strip 12 and the groove 13, the clamping connection between the molecular sieve 1 and the molecular sieve 1 is realized, so that the molecular sieve 1 and the molecular sieve 1 are spliced in the horizontal direction, that is, single-layer splicing. The clamping connection between the molecular sieve 1 and the molecular sieve 1 ensures the stability of the connection, avoids the misalignment phenomenon during the connection, and improves the assembly convenience.
[0039] The molecular sieve body 11 is in a cuboid shape. The plurality of honeycomb holes 111 on the molecular sieve body 11 are arranged in sequence. The cross section of the honeycomb hole 111 is in a hexagonal shape.
[0040] A plurality of edge grooves 112 are arranged on each side surface of the molecular sieve body 11 in sequence. The edge groove 112 is in a half-honeycomb shape, and the opening of the edge groove 112 is outward. The edge groove 112 is penetrated along the height direction of the molecular sieve body 11. The half-honeycomb shape refers to the shape of half of the honeycomb hole 111 in a hexagonal shape. Two edge grooves 112 are enclosed to form a complete through hole, and the cross section of the through hole is in a hexagonal shape.
[0041] In this embodiment, the outer contour of the edge groove 112 is in an isosceles trapezoidal shape. That is, the hexagonal shape is divided along the symmetry axis passing through the vertex to obtain the edge groove 112.
[0042] When the molecular sieve 1 is spliced by a single layer, that is, when the two adjacent molecular sieves 1 are clamped, the edge grooves 112 of the two adjacent molecular sieve bodies 11 are correspondingly arranged and form through holes with a hexagonal cross section. Specifically, the edge grooves 112 located on the outer side and the edge grooves 112 between them will be assembled into a complete hexagonal hole, that is, a honeycomb hole 111, thereby expanding the number of honeycomb holes 111 of the assembled molecular sieve 1, and further improving the adsorption capacity.
[0043] A plurality of protrusions 12 are arranged on the two adjacent sides of the molecular sieve body 11, and a plurality of grooves 13 are arranged on the remaining two sides. Specifically, the four sides of the molecular sieve body 11 are a first side, a second side, a third side, and a fourth side, and the first side, the second side, the third side, and the fourth side are connected end to end. Exemplarily, the outer periphery of the first side and the second side is provided with the protrusion 12, and the third side and the fourth side are provided with the groove 13.
[0044] The protrusion 12 and the groove 13 are arranged at the corners of the molecular sieve body 11. Therefore, the opposite ends of the first side and the second side are provided with the protrusion 12, and the opposite sides of the third side and the fourth side are provided with the groove 13.
[0045] In other embodiments, the protrusions 12 can be arranged along the length of the first side and the second side. For example, the protrusions 12 can also be arranged at the middle of the first side and the second side. Adaptively, the grooves 13 can also be arranged at the middle of the third side and the fourth side. The specific number and arrangement position are arranged according to actual needs.
[0046] Specifically, the protrusion 12 protrudes outward from the outer periphery of the molecular sieve body 11, and the groove 13 is recessed inward. When the protrusion 12 is clamped in the groove 13 of another molecular sieve 1, the corresponding side of the protrusion 12 abuts against the corresponding side of the groove 13. This design enables the molecular sieve 1 to avoid space waste when splicing the molecular sieve 1 with the molecular sieve 1.
[0047] The cross section of the protrusion 12 is square, and the shape of the groove 13 is matched with the shape of the protrusion 12. In other embodiments, the protrusion 12 can also be arc-shaped, dovetail-shaped, or other irregular shapes, which are arranged according to actual needs. The groove 13 is matched with the protrusion 12.
[0048] In this embodiment, the protrusion 12 extends from the top to the bottom of the molecular sieve body 11. In other embodiments, the protrusion 12 can be a plurality of protrusions arranged along the height direction. Or the top of the protrusion 12 does not extend to the top of the molecular sieve body 11. Or the top of the protrusion 12 does not extend to the bottom of the molecular sieve body 11.
[0049] The groove 13 extends from the top to the bottom of the molecular sieve body 11 and penetrates along the height direction.
[0050] The connecting structure further comprises a plurality of protrusions 14 and a plurality of recesses 15. The protrusions 14 of the lower molecular sieve 1 can be inserted into the recesses 15 of the upper molecular sieve 1, thereby connecting the two molecular sieves 1 and achieving stacking.
[0051] Specifically, the plurality of protrusions 14 are arranged on the top of the molecular sieve body 11 and protrude upward beyond the molecular sieve body 11. The plurality of protrusions 14 are arranged along the circumference of the molecular sieve body 11 at intervals.
[0052] The plurality of recesses 15 are arranged on the bottom of the molecular sieve body 11. The plurality of recesses 15 are arranged in one-to-one correspondence with the plurality of protrusions 14.
[0053] The cross section of the protrusion 14 is circular, and the shape of the recess 15 is adapted to the shape of the protrusion 14. In other embodiments, the protrusion 14 can also be square, triangular or of other shapes, which are selected according to actual conditions. The recess 15 is arranged according to the shape of the protrusion 14.
[0054] The protrusions 14 and the recesses 15 are arranged at the corners of the molecular sieve body 11. That is, each molecular sieve 1 comprises four protrusions 14 and four recesses 15.
[0055] The arrangement of the recesses 15 on the bottom facilitates the placement of the lowermost molecular sieve 1, and then the molecular sieves 1 are stacked layer by layer, improving the stacking accuracy and ensuring the stability between the stacked molecular sieves 1.
[0056] The protrusions 14 and the recesses 15 also have a positioning effect, so that the alignment between the honeycomb holes 111 and the alignment between the edge grooves 112 of the upper and lower molecular sieves 1 are accurate, and the communication between the honeycomb holes 111 and the edge grooves 112 of the upper and lower molecular sieves 1 is ensured.
[0057] The application also provides a molecular sieve composition comprising a plurality of the above-mentioned molecular sieves 1. The plurality of molecular sieves 1 are arranged in the horizontal direction and connected by the protrusions 12 and the recesses 13.
[0058] By inserting the protrusion 12 of one molecular sieve 1 into the recess 13 of the adjacent molecular sieve 1, the molecular sieves 1 are connected in sequence, and the connection between the plurality of molecular sieves 1 in the horizontal direction is achieved.
[0059] When the molecular sieves 1 are connected, the two edge grooves 112 corresponding to the half-honeycomb shape together form a complete honeycomb hole 111, which expands the number of honeycomb holes 111 and increases the adsorption effect on impurities.
[0060] Referring to Figure 4 , four molecular sieves 1 are connected to form a molecular sieve composition. Figure 4The view direction is taken as a reference, the convex strip 12 is arranged on the left side and the lower side, and the groove 13 is arranged on the right side and the upper side.
[0061] The molecular sieve composition further comprises a plurality of molecular sieves 1 stacked along the height direction of the molecular sieve body 11. The convex strip 12 cooperates with the groove 13 to realize the clamping connection between the plurality of molecular sieves 1.
[0062] The connection between the two molecular sieves 1 is realized by inserting the convex column 14 of the lower molecular sieve 1 into the concave hole 15 of the upper molecular sieve 1, and the stacking between the molecular sieves 1 is realized. By inserting the convex column 14 into the concave hole 15, the misalignment phenomenon is avoided, the precision during stacking is improved, and the stability between the stacked molecular sieves 1 is ensured.
[0063] Through the precise positioning between the convex column 14 and the concave hole 15, not only the alignment between the honeycomb holes 111 and the honeycomb holes 111 of the two molecular sieves 1 is ensured, but also the alignment between the edge grooves 112 of the upper and lower molecular sieves 1 during stacking is ensured, thereby ensuring the communication of the honeycomb holes 111 between the upper and lower molecular sieves 1.
[0064] In summary, the molecular sieve 1 has the following advantages:
[0065] 1. Through the structure of the convex strip 12 and the groove 13, the clamping connection between the molecular sieve 1 and another molecular sieve 1 is realized, thereby realizing the splicing of the molecular sieve 1 and the molecular sieve 1 in the horizontal direction, i.e. single-layer splicing. The clamping connection between the molecular sieve 1 and the molecular sieve 1 ensures the stability of the connection, avoids the misalignment phenomenon during connection, and improves the assembly convenience.
[0066] 2. The connection between the two molecular sieves 1 is realized by inserting the convex column 14 of the lower molecular sieve 1 into the concave hole 15 of the upper molecular sieve 1, and the stacking between the molecular sieves 1 is realized. By inserting the convex column 14 into the concave hole 15, the misalignment phenomenon is avoided, the precision during stacking is improved, and the stability between the stacked molecular sieves 1 is ensured.
[0067] 3. The edge groove 112 on the outer side of the molecular sieve 1 can correspond to the edge groove 112 of other molecular sieves 1 to form a through hole with a hexagonal cross section, thereby expanding the number of honeycomb holes 111 of the assembled molecular sieve 1, and further improving the adsorption capacity.
