Description

Technical Field

[0001] This invention relates to the field of coal chemical technology, specifically to a reforming agent distributor and a carbon-containing material conversion and reforming reactor having the same. Background Technology

[0002] The carbonaceous material conversion and reforming reactor uses carbonaceous particulate matter as raw material and steam, oxygen, carbon dioxide and their mixtures as oxidants. The reactor is designed with a non-cylindrical variable diameter to form a mixed bed. Secondary conversion and reforming are achieved by adding reforming agents such as steam, oxygen, carbon dioxide, hydrogen, tar and their mixtures. The product gas composition is adjusted according to the predetermined product process route to improve reactor efficiency. Composite gas film bricks with catalytic function are used to introduce gas film gas. The gas film gas is used to cool the gas film bricks to protect the furnace wall while being heated and undergoing chain-breaking conversion.

[0003] In a carbonaceous material reforming reactor, the reforming agent needs to be introduced and distributed using a reforming agent distributor. The reactor's outer shell is a pressure vessel, housing a heat-resistant lining and components such as the reforming agent distributor. During operation, temperature variations occur in these components, creating temperature differences. Simultaneously, the reforming agent introduced and distributed by the distributor can be one or more of the following: steam, oxygen, carbon dioxide, hydrogen, tar, or mixtures thereof. This alternation of different reforming agents, coupled with their varying temperatures, causes repeated temperature changes within the distributor itself. These temperature variations and differences create expansion differences within the pressure vessel shell, the heat-resistant lining, and the reforming agent distributor, ultimately preventing the carbonaceous material reforming reactor from functioning properly. Summary of the Invention

[0004] In view of this, the present invention provides a reforming agent distributor and a carbonaceous material conversion reforming reactor having the same, to solve the problem that existing carbonaceous material conversion reforming reactors are prone to expansion differences due to temperature changes and temperature variations. The reforming agent distributor provided by the present invention, by providing a curved portion on the feeding ring, allows the curved portion to deform when the shell and / or refractory brick structure experiences expansion differences due to temperature changes and / or temperature variations, fully compensating for the expansion differences axially and / or radially. Furthermore, by filling the space between the outer peripheral wall of the refractory brick structure and the inner peripheral wall of the shell with refractory filler, the refractory filler covers the feeding ring, not only providing isolation and protection for the feeding ring, but also ensuring that the refractory filler, made of non-solidifying plastic, can deform together with the curved portion when the shell and / or refractory brick structure experiences expansion differences due to temperature changes and / or temperature variations, fully compensating for the expansion differences axially and / or radially, thereby ensuring the normal operation of all components.

[0005] In a first aspect, the present invention provides a reforming agent distributor, comprising:

[0006] case;

[0007] The refractory brick structure has its outer peripheral wall spaced apart from the inner peripheral wall of the shell to form a receiving gap.

[0008] A fabric ring is disposed within the receiving gap, and the fabric ring is circumferentially disposed on the inner peripheral wall of the housing;

[0009] The fabric ring includes multiple bends, which are evenly arranged around the circumference of the fabric ring. The bends are adapted to deform when a difference in expansion occurs in the shell and / or refractory brick structure to compensate for the difference in expansion.

[0010] Refractory filler, made of non-solidified plastic, is embedded in the containment gap and covered with a fabric ring. The refractory filler is adapted to deform to compensate for the expansion difference when the shell and / or refractory brick structure is subjected to expansion difference.

[0011] By incorporating a bend in the fabric ring, the bend can deform when the shell and / or refractory brick structure experiences expansion differences due to temperature changes and / or temperature variations, fully compensating for the expansion differences axially and / or radially. Furthermore, by filling the space between the outer peripheral wall of the refractory brick structure and the inner peripheral wall of the shell with refractory filler, the refractory filler covers the fabric ring, providing not only isolation and protection for the fabric ring but also ensuring proper functioning of all components when the shell and / or refractory brick structure experiences expansion differences due to temperature changes and / or temperature variations, as the refractory filler is made of non-solidifying plastic.

[0012] In one optional embodiment, the distance between the fabric ring and the inner peripheral wall of the shell is H, where H satisfies 10mm≤H≤80mm. This facilitates heat transfer control between the fabric ring 30 and the inner peripheral wall of the shell 10, ensures the effective utilization section of the carbon-containing material conversion reforming reactor, improves the space utilization rate of the carbon-containing material conversion reforming reactor, and ensures the coordination of the assembly structure of the reforming agent distributor.

[0013] In one optional embodiment, the reforming agent distributor further includes a fixing clip, which is fixedly disposed on the inner peripheral wall of the housing. The fixing clip is adapted to position the fabric ring. Positioning the fabric ring 30 by the fixing clip 50 ensures the distance between the fabric ring 30 and the inner peripheral wall of the housing 10. This not only ensures the reliability of the bent portion 31 on the fabric ring 30 in the process of compensating for expansion difference, but also facilitates the control of heat transfer between the fabric ring 30 and the inner peripheral wall of the housing 10.

[0014] In one alternative embodiment, the reforming agent distributor further includes a feed pipe disposed on the side of the fabric ring radially close to the housing, the feed pipe being adapted to pass through the housing and introduce material into the fabric ring;

[0015] A fitting gap is formed between the feed pipe and the shell, and the fitting gap is filled with ceramic fibers. By filling the gap between the feed pipe 60 and the shell 10 with ceramic fibers 61, on the one hand, the relevant components can expand and contract freely under temperature rise changes, and on the other hand, the heat of the reforming agent can be further prevented from being transferred to the shell 10 to reduce heat loss and protect the shell 10.

[0016] In one optional embodiment, the refractory brick structure includes a first brick, the outer peripheral wall of the first brick is adapted to be spaced apart from the inner peripheral wall of the shell to form a receiving gap, and the inner peripheral wall of the first brick is adapted to enclose and form a reaction cavity.

[0017] The reforming agent distributor also includes a jet assembly. One radial end of the jet assembly is connected to the cloth ring, and the other end is adapted to pass through the first brick body radially and jet into the reaction cavity. Several jet assemblies 70 are evenly arranged around the cloth ring 30 to make the distribution of the reforming agent into the reaction cavity more uniform, effectively ensuring the reforming reaction efficiency. At the same time, it enables the reforming agent distributor to form a coolant-free cooling structure, so that heat energy can be fully utilized, which is conducive to improving reaction efficiency and saving energy.

[0018] In one optional embodiment, the refractory brick structure further includes a second brick body disposed between the jet assembly and the first brick body, and the second brick body covering the outer peripheral wall of the jet assembly; the wear resistance, corrosion resistance, high temperature resistance and oxidation resistance of the second brick body 22 and the first brick body 21 can protect the reforming agent distributor from damage caused by the working conditions in the reaction chamber.

[0019] In one alternative embodiment, the jet assembly includes a splitter tube and a nozzle, one end of the splitter tube being connected to a fabric ring and the other end being connected to the nozzle.

[0020] The flow cross-sectional area of ​​the diverter is larger than that of the nozzle. After the reforming agent enters the nozzle 72 through the diverter 71, it is sprayed out, and the flow rate increases. This allows the reforming agent to be sprayed out of the nozzle 72 at high speed and leave the refractory brick structure 20 at a certain safe distance before reacting. This can effectively prevent the refractory brick structure 20 and the nozzle 72 from being damaged by abrasion, high temperature and oxidation under normal working conditions.

[0021] In one alternative embodiment, the nozzle includes an outlet section and a transition section, one end of the transition section being connected to a splitter pipe and the other end being connected to the outlet section.

[0022] The transition section has a larger cross-sectional area than the outlet section, and the transition section has a smaller cross-sectional area than the distributor pipe. This allows the reforming agent to enter the nozzle 72 from the distributor pipe 71 and then be ejected, increasing the kinetic energy of the reforming agent's flow velocity while decreasing its pressure energy. The length-to-diameter ratio of the outlet section is γ, which satisfies 3≤γ≤6. This maintains the stable injection kinetic energy of the reforming agent and controls the resistance drop within the specified working range. By setting the outlet section 721 and the transition section 722, the speed and kinetic energy of the reforming agent when it leaves the nozzle 72 are guaranteed and improved. At the same time, the resistance drop can be controlled, thus controlling and saving energy consumption. Meanwhile, the length-to-diameter ratio of the outlet section 721, by satisfying 3≤γ≤6, further stabilizes the injection kinetic energy, allowing the reforming agent to leave the refractory brick structure 20 at a certain safe distance after being ejected at high speed from the nozzle 72 before reacting. This effectively prevents the refractory brick structure 20 and the nozzle 72 from being damaged by abrasion, high temperature, and oxidation under normal working conditions.

[0023] Secondly, the present invention also provides a carbon-containing material conversion and reforming reactor, comprising: a carbon-containing material conversion and reforming reactor body, and a reforming agent distributor as described above.

[0024] In one optional embodiment, the carbonaceous material reforming reactor further includes an insulating composite layer. The insulating composite layer is disposed on the surface of the reforming agent distributor that contacts the internal process medium of the carbonaceous material reforming reactor body. Through the strengthening effect of the insulating composite layer 80, the reforming agent distributor can have a longer trouble-free service life. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The following is combined with Figures 1 to 4 The following describes embodiments of the present invention.

[0041] According to an embodiment of the present invention, in one aspect, a reforming agent distributor is provided, comprising:

[0042] Casing 10;

[0043] The refractory brick structure 20 has its outer peripheral wall and the inner peripheral wall of the shell 10 arranged radially to form a receiving gap, which is suitable for accommodating refractory filler 40.

[0044] A fabric ring 30 is disposed within the receiving gap, and the fabric ring 30 is circumferentially disposed on the inner peripheral wall of the housing 10;

[0045] The fabric loop 30 includes multiple bends 31, see [link to relevant documentation]. Figure 3As shown, the bending section 31 has a U-shaped structure, and the bending section 31 is arranged along the axial direction. Multiple bending sections 31 are evenly arranged around the circumference of the feeding ring 30. The number of bending sections 31 can be set according to the diameter of the feeding ring 30. Specifically, 3 to 24 bending sections 31 can be evenly arranged around the feeding ring 30, so as to ensure the economic efficiency of the carbonaceous material conversion reforming reactor while fully compensating for the expansion difference. The bending section 31 is adapted to deform when the shell 10 and / or refractory brick structure 20 generate an expansion difference to compensate for the expansion difference.

[0046] Furthermore, the placing ring 30 can be made by bending and welding steel pipes or by welding steel pipes and elbow fittings into a ring, which has excellent pressure bearing performance and can withstand various internal and external pressure differences. The placing ring 30 can also be made of wear-resistant and corrosion-resistant alloy material, and the wall thickness of the placing ring 30 can be determined according to parameters such as working pressure and temperature.

[0047] Refractory filler 40, made of non-solidified plastic, is built into the receiving gap and covers the fabric ring 30. Refractory filler 40 is adapted to deform to compensate for the expansion difference when the shell 10 and / or refractory brick structure 20 are generated.

[0048] The reforming agent distributor provided in this embodiment, by providing a curved portion 31 on the fabric ring 30, allows the curved portion 31 to deform when the shell 10 and / or the refractory brick structure 20 experience expansion differences due to temperature changes and / or temperature variations, thus fully compensating for the expansion differences axially and / or radially. Furthermore, by filling the space between the outer peripheral wall of the refractory brick structure 20 and the inner peripheral wall of the shell 10 with refractory filler 40, the refractory filler 40 covers the fabric ring 30, providing not only isolation and protection for the fabric ring 30, but also ensuring that the refractory filler 40, being made of non-solidifying plastic, can deform together with the curved portion 31 when the shell 10 and / or the refractory brick structure 20 experience expansion differences due to temperature changes and / or temperature variations, thereby fully compensating for the expansion differences axially and / or radially, and ensuring the normal operation of all components.

[0049] In one embodiment, the distance between the fabric ring 30 and the inner peripheral wall of the shell 10 cannot be too small; otherwise, it will not only hinder the heat transfer control between the fabric ring 30 and the inner peripheral wall of the shell 10, but also easily reduce the coordination of the assembly structure of the reforming agent distributor. Therefore, the distance H between the fabric ring 30 and the inner peripheral wall of the shell 10 must satisfy H≥10mm. The distance between the fabric ring 30 and the inner peripheral wall of the shell 10 also cannot be too large; otherwise, it will easily lead to a reduction in the effective utilization section of the carbonaceous material conversion reforming reactor, reducing the space utilization rate of the carbonaceous material conversion reforming reactor and the coordination of the assembly structure of the reforming agent distributor. Therefore, the distance H between the fabric ring 30 and the inner peripheral wall of the shell 10 must also satisfy H≤80mm. Please refer to [link to previous text]. Figure 1 As shown, in this embodiment, the distance H between the fabric ring 30 and the inner peripheral wall of the shell 10 satisfies 10mm≤H≤80mm, which is beneficial to the heat transfer control between the fabric ring 30 and the inner peripheral wall of the shell 10, and can also ensure the effective utilization section of the carbon-containing material conversion reforming reactor, improve the space utilization rate of the carbon-containing material conversion reforming reactor, and at the same time ensure the coordination of the assembly structure of the reforming agent distributor.

[0050] In one embodiment, the reforming agent distributor further includes a retaining clip 50, see [link to relevant documentation]. Figure 1 As shown, the fixing clip 50 is fixedly installed on the inner peripheral wall of the housing 10. The fixing clip 50 is used to position the fabric ring 30, thereby ensuring the distance between the fabric ring 30 and the inner peripheral wall of the housing 10. This not only ensures the reliability of the bent part 31 on the fabric ring 30 in the process of compensating for expansion difference, but also facilitates the control of heat transfer between the fabric ring 30 and the inner peripheral wall of the housing 10.

[0051] In one embodiment, the reforming agent distributor further includes a feed pipe 60. The feed pipe 60 can be made of seamless steel or a wear-resistant and corrosion-resistant alloy material, depending on the working pressure, temperature, and medium characteristics. (See [link to relevant documentation]). Figure 1 and Figure 2 As shown, the feed pipe 60 is disposed on the side of the fabric ring 30 radially close to the housing 10, and the feed pipe 60 is adapted to pass through the housing 10 and introduce material into the fabric ring 30;

[0052] A feed flange 62 is provided at the end of the feed pipe 60 that is radially away from the cloth ring 30. The feed flange 62 can be made of wear-resistant and corrosion-resistant alloy material according to the working pressure, temperature and medium characteristics. The feed flange 62 is suitable for connecting external pipelines and introducing reforming agent. The feed pipe 60 is suitable for connecting the feed flange 62 and the cloth ring 30 and positioning the distance between the feed flange 62 and the cloth ring 30.

[0053] Please see Figure 1 As shown, a fitting gap is formed between the feed pipe 60 and the shell 10, and the fitting gap is filled with ceramic fibers 61. By filling the gap between the feed pipe 60 and the shell 10 with ceramic fibers 61, on the one hand, the relevant components can expand and contract freely under temperature rise changes, and on the other hand, the heat of the reforming agent can be further prevented from being transferred to the shell 10 to reduce heat loss and protect the shell 10.

[0054] Specifically, the reforming agent distributor also includes a mounting flange 63, and the feeding ring 30, feed pipe 60, feed flange 62 and mounting flange 63 can be welded together as a whole.

[0055] In one embodiment, see Figure 1As shown, the refractory brick structure 20 includes a first brick 21, which is a refractory brick of ordinary structure. The outer peripheral wall of the first brick 21 is adapted to be spaced apart from the inner peripheral wall of the shell 10 to form a receiving gap. The inner peripheral wall of the first brick 21 is adapted to enclose and form a reaction cavity. The wear resistance, corrosion resistance, high temperature resistance and oxidation resistance of the first brick 21 can protect the reforming agent distributor from damage caused by the working conditions inside the reaction cavity.

[0056] The reforming agent distributor also includes a jet assembly 70. One radial end of the jet assembly 70 is connected to the cloth ring 30, and the other end is adapted to pass radially through the first brick 21 and jet into the reaction cavity. Several groups of jet assemblies 70 can be set according to the diameter of the cloth ring 30. Several jet assemblies 70 are evenly arranged around the circumference of the cloth ring 30 so that the distribution of the reforming agent into the reaction cavity tends to be uniform, effectively ensuring the reforming reaction efficiency. At the same time, it can make the reforming agent distributor form a coolant-free structure, so that the heat energy can be fully utilized, which is conducive to improving the reaction efficiency and saving energy.

[0057] Specifically, the jet assembly 70 can be made of alloy, cermet, or a combination of alloy and cermet materials to ensure the jet assembly 70’s temperature resistance, wear resistance, corrosion resistance and oxidation resistance under working conditions, thereby extending the service life of the jet assembly 70.

[0058] Specifically, the jet assembly 70 and the fabric ring 30 can be connected by thread or welding.

[0059] In one embodiment, see Figure 1 As shown, the refractory brick structure 20 also includes a second brick 22, which is a refractory brick with an irregular shape. The second brick 22 is disposed between the jet assembly 70 and the first brick 21. The second brick 22 covers the outer peripheral wall of the jet assembly 70. The wear resistance, corrosion resistance, high temperature resistance and oxidation resistance of the second brick 22 and the first brick 21 can protect the reformer distributor from damage caused by the working conditions in the reaction chamber.

[0060] In one embodiment, the inner channel of the jet assembly 70 is a tapered combination of a cylinder and a cone. (See also...) Figure 4 As shown, the jet assembly 70 includes a flow divider 71 and a nozzle 72. The flow divider 71 and the nozzle 72 can be integrally formed or assembled separately. One end of the flow divider 71 is connected to the material distribution ring 30, and the other end is connected to the nozzle 72. The flow cross-sectional area of ​​the flow divider 71 is larger than that of the nozzle 72. After the reforming agent enters the nozzle 72 through the flow divider 71, it is sprayed out, and the flow velocity increases. This allows the reforming agent to be sprayed out of the nozzle 72 at high speed and leave a certain safe distance from the refractory brick structure 20 before reacting. This effectively avoids the refractory brick structure 20 and the nozzle 72 from the damage caused by abrasion, high temperature and oxidation under normal working conditions.

[0061] Specifically, since the working conditions of the nozzle 72 are more severe, the jet assembly 70 can adopt a split assembly structure, with the diverter pipe 71 and the nozzle 72 being detachably connected, and the material properties of the nozzle 72 being improved locally. It is also easy to manufacture, inspect and replace, which helps to reduce the cost of use and maintenance.

[0062] In one embodiment, see Figure 4 As shown, the nozzle 72 includes an outlet section 721 and a transition section 722. One end of the transition section 722 is connected to the split pipe 71, and the other end is connected to the outlet section 721. The transition section 722 adopts a truncated cone structure to ensure that the reforming agent is evenly distributed in each jet assembly 70 and its nozzle 72.

[0063] In this design, the flow cross-sectional area of ​​the transition section 722 is larger than that of the outlet section 721, and the flow cross-sectional area of ​​the transition section 722 is smaller than that of the diverter pipe 71. This allows the reforming agent to enter the nozzle 72 from the diverter pipe 71 and then be ejected, increasing the flow velocity kinetic energy and decreasing the pressure energy of the reforming agent. The length-to-diameter ratio of the outlet section 721 is γ, where γ satisfies 3≤γ≤6, to maintain the stable injection kinetic energy of the reforming agent turbulence and control the resistance drop within the specified operating range. This is achieved by setting the outlet section 721 and... The transition section 722 ensures and enhances the speed and kinetic energy of the reforming agent when it leaves the nozzle 72, while controlling the resistance drop, thus controlling and saving energy consumption. Meanwhile, the length-to-diameter ratio of the outlet section 721, by satisfying 3≤γ≤6, further stabilizes the injection kinetic energy, allowing the reforming agent to leave the refractory brick structure 20 at a certain safe distance after being sprayed at high speed from the nozzle 72 before reacting. This effectively avoids the refractory brick structure 20 and the nozzle 72 from being damaged by abrasion, high temperature and oxidation under normal operating conditions.

[0064] According to an embodiment of the present invention, another aspect provides a carbon-containing material conversion and reforming reactor, comprising: a carbon-containing material conversion and reforming reactor body, and a reforming agent distributor as described above.

[0065] In one embodiment, the carbon-containing material conversion reforming reactor further includes an insulation material composite layer 80. The insulation material composite layer 80 can be a composite layer of silicate nano-aerosol and water-soluble insulation material. The composite layer is a near-zero porosity insulation material filled with silicate nano-aerosol, which has the characteristics of good insulation performance, resistance to water vapor erosion, high temperature resistance and oxidation resistance. The insulation material composite layer 80 is disposed on the surface of the metal parts of the reforming agent distributor that are in contact with the internal process medium of the carbon-containing material conversion reforming reactor body. Through the strengthening effect of the insulation material composite layer 80, the reforming agent distributor can have a longer trouble-free service life.
