Description

Technical Field

[0001] This invention relates to the field of reactor technology, and in particular to a shift reactor for the production of green methanol from biomass feedstock. Background Technology

[0002] In the process of producing green methanol from biomass feedstock, the shift reactor adjusts the syngas ratio through a water-gas shift reaction, and its core is the efficient contact between the catalyst and the feedstock gas. Existing shift reactors mostly adopt a fixed-bed structure, with the catalyst statically stacked inside the reactor. This presents the following problems: First, the reaction path is fixed and relatively short, resulting in limited contact time between the feedstock gas and the catalyst, easily leading to low conversion rates due to insufficient mass transfer. Second, long-term static stacking of the catalyst can cause localized compaction, reducing the effective contact area. Simultaneously, reaction byproducts (such as carbon powder and salts) easily remain on the reactor inner wall, affecting heat transfer and gas flow. Third, the reaction path length cannot be adjusted according to the feedstock gas composition, easily resulting in wasted path space for low-concentration feedstock gases. Furthermore, once the catalyst is placed in a fixed position, the underutilized portion is difficult to reuse, leading to high catalyst loss rates and increased production costs.

[0003] To address the aforementioned issues, this invention proposes a shift reactor for preparing green methanol from biomass feedstock. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing shift reactors, which mostly employ a fixed-bed structure, with the catalyst statically stacked within the shift reaction chamber. This results in a fixed and short reaction path, limited contact time between the feed gas and the catalyst, localized compaction of the catalyst due to long-term static stacking, reduced effective contact area, and easy residue of reaction byproducts on the reactor inner wall, affecting heat transfer and gas flow. Furthermore, the reaction path length cannot be adjusted according to the feed gas composition, leading to high catalyst loss and increased production costs. The invention proposes a shift reactor for the production of green methanol from biomass feedstock.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A shift reactor for producing green methanol from biomass feedstock includes a shift reaction chamber container, wherein an adjustable reaction mechanism is provided inside the shift reaction chamber container.

[0007] The adjustable reaction mechanism includes a path-changing conveying cylinder structure, which is fixedly connected in the reaction chamber container. An elastic spiral partition structure is provided outside the path-changing conveying cylinder structure. Two movable external mesh structures are fixedly connected to the elastic spiral partition structure. Pressurizing components are provided on both the upper and lower sides of the elastic spiral partition structure. The two pressurizing components are connected to both ends of the path-changing conveying cylinder structure.

[0008] The internal structure of the changing path conveying cylinder is provided with an airflow path conversion component. The portion of the airflow path conversion component extending out of the changing path conveying cylinder structure is connected to two inner combined mesh sealing components. The two inner combined mesh sealing components are respectively arranged on both sides of the movable inner combined mesh structure, and the movable inner combined mesh structure is fixedly connected to the elastic spiral partition structure.

[0009] Preferably, four catalyst discharge ports are provided on one side of the conversion reaction chamber container.

[0010] Preferably, the movable outer mesh structure consists of two mesh grids, which are arranged in an alternating manner.

[0011] Preferably, the changing path conveying cylinder structure has an airflow changing port.

[0012] Preferably, the pressurization assembly includes two cylinder fixing plates, which are fixedly connected to the path changing conveyor cylinder structure. Cylinder telescopic devices are fixedly connected to the cylinder fixing plates, and annular rings are fixedly connected to one end of each of the two cylinder telescopic devices. The annular rings are fitted onto the path changing conveyor cylinder structure.

[0013] Preferably, an annular mesh is fixedly connected to the annular ring, the annular mesh is sleeved on the changing path conveying cylinder structure, and the annular mesh overlaps with the elastic spiral partition structure.

[0014] Preferably, the movable inner combined mesh structure consists of two mesh frames, which are arranged in an alternating manner.

[0015] Preferably, the inner mesh sealing assembly includes a sealing mesh layer, which is laid on the mesh frame and two transverse guide rails are fixedly connected to the mesh frame. Two transverse guide grooves are formed on the sealing mesh layer, and the sealing mesh layer is slidably connected to the transverse guide rails through the transverse guide grooves.

[0016] Preferably, a longitudinal guide rail is fixedly connected to the sealing mesh layer, the longitudinal guide rail is slidably connected to the longitudinal guide slide rail, a connector is fixedly connected to the longitudinal guide slide rail, a guide slide rod is fixedly connected to one side of the connector, the guide slide rod is sleeved in the guide slide sleeve, and the guide slide sleeve is fixedly installed on the changing path conveying cylinder structure.

[0017] Preferably, the airflow path conversion component includes a cylinder mounting base, which is fixedly connected to the path conversion conveying cylinder structure. A cylinder telescopic structure is fixedly installed on the cylinder mounting base. A support plate is fixedly connected to one end of the cylinder telescopic structure. One side of the support plate is fixedly connected to two guide slide rods. A sealing plate is fixedly connected to one side of the support plate. The sealing plate is disposed in the airflow conversion port.

[0018] Compared with existing technologies, the present invention provides a shift reactor for preparing green methanol from biomass feedstock, which has the following beneficial effects:

[0019] 1. This biomass feedstock-to-green methanol shift reactor utilizes an elastic spiral septum structure to store the catalyst, arranging it spirally within the shift reaction chamber. This effectively extends the reaction path of the feedstock gas, providing more sufficient contact time for the water-gas shift reaction. Furthermore, the pressurization component reciprocates the pressurization of the elastic spiral septum structure, allowing it to elastically recover its shape. This expansion and contraction of the elastic spiral septum cleans the inner wall of the shift reaction chamber. The expansion and contraction of the elastic spiral septum also causes the internal catalyst to sway or shift, breaking the static packing state and significantly increasing the contact area between the feedstock gas and the active sites of the catalyst, thus improving mass transfer efficiency and providing higher-quality feedstock gas for subsequent methanol synthesis.

[0020] 2. This biomass feedstock-to-green methanol conversion reactor uses a cylinder telescopic structure to retract the support plate, causing the sealing plate to detach from the gas flow change port. Simultaneously, the support plate moves the guide slide rod, which, through a connector, moves the longitudinal guide slide rail. The longitudinal guide slide rail, in turn, moves the sealing mesh layer, causing the mesh openings of the sealing mesh layer to be misaligned with the mesh openings of the movable inner combined mesh structure, maintaining a seal. At this point, the feedstock gas can be directly discharged upwards through the gas flow change port and the conversion path conveying cylinder structure. This method allows for selection of the path length based on the material to be processed, avoiding resource waste caused by long paths and thus improving the operational flexibility of the equipment.

[0021] 3. The shift reactor for producing green methanol from biomass feedstock opens the gas flow change port through a gas flow path conversion component. This component, in turn, drives the internal combined mesh sealing component to close the movable internal combined mesh structure, allowing the feed gas to be directly discharged through the gas flow change port. This avoids resource waste caused by the feed gas entering the upper catalyst section. Furthermore, since the upper feed gas is in later contact with the reaction and thus not fully activated, the catalyst can be directly discharged by opening the lower catalyst discharge port and collected by opening the upper catalyst discharge port. This method facilitates the transfer of insufficiently consumed catalyst from the less frequently used upper path to the lower path, allowing the catalyst to be reused in a region with higher reaction intensity, fully utilizing its activity potential, reducing resource waste caused by premature catalyst disposal, and facilitating catalyst separation. This effectively reduces the frequency of catalyst procurement and replacement, thus lowering costs. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] Example 1: Refer to Figures 1-7 A shift reactor for preparing green methanol from biomass feedstock includes a shift reaction chamber container 100, and an adjustable reaction mechanism 200 is provided inside the shift reaction chamber container 100.

[0036] The adjustable reaction mechanism 200 includes a path-changing conveying cylinder structure 201, which is fixedly connected to the reaction chamber container 100. An elastic spiral partition structure 202 is disposed outside the path-changing conveying cylinder structure 201. Two movable external combined mesh structures 204 are fixedly connected to the elastic spiral partition structure 202. Each movable external combined mesh structure 204 consists of two mesh grids arranged in an alternating manner. The combined mesh grids can intercept the catalyst, preventing the need for replacement of the catalyst below. The catalyst above flows downwards, allowing the grid to accommodate segmented catalyst storage, and the mesh size ensures the smooth ascent of the raw material gas. Simultaneously, the staggered arrangement of the two grids allows the elastic spiral partition structure 202 to extend and retract smoothly. Pressurization components 203 are provided on both the upper and lower sides of the elastic spiral partition structure 202. Each pressurization component 203 includes two cylinder fixing plates 2031, which are fixedly connected to the path-changing conveying cylinder structure 201. Gas cylinders are fixedly connected to the cylinder fixing plates 2031. The cylinder telescopic device 2032 is fixed by the cylinder fixing plate 2031, ensuring its stability and allowing it to smoothly drive the annular ring 2033. The annular ring 2033 applies pressure to the annular mesh 2034, causing the elastic spiral partition structure 202 to deform. When the cylinder telescopic device 2032 retracts, the elastic spiral partition structure 202 elastically recovers its shape, thus maintaining catalyst movement, preventing local compaction, and ensuring good ventilation. Each cylinder telescopic device 2032 has an annular ring 2033 fixedly connected to one end. The annular ring 2033 is sleeved on the path changing conveyor cylinder structure 201. An annular net 2034 is fixedly connected to the annular ring 2033. The annular net 2034 is breathable, allowing the raw material gas to be discharged smoothly upward. The annular net 2034 is sleeved on the path changing conveyor cylinder structure 201, and the annular net 2034 overlaps with the elastic spiral partition structure 202. Two pressurizing components 203 are connected to both ends of the path changing conveyor cylinder structure 201.

[0037] The internal structure of the path-changing conveying cylinder 201 is provided with an airflow path conversion component 207. The part of the airflow path conversion component 207 extending out of the path-changing conveying cylinder 201 is connected to two inner combined mesh sealing components 206. The two inner combined mesh sealing components 206 are respectively arranged on both sides of the movable inner combined mesh structure 205, and the movable inner combined mesh structure 205 is fixedly connected to the elastic spiral partition structure 202.

[0038] In this embodiment: the elastic spiral partition structure 202 can store the catalyst, allowing the catalyst to be arranged spirally in the shift reaction chamber container 100, effectively extending the reaction path of the raw gas and providing more sufficient contact time for the water-gas shift reaction. Furthermore, the cylinder extension device 2032 pushes the annular ring 2033 to move, which in turn drives the annular mesh 2034 to move, causing the annular mesh 2034 to pressurize the elastic spiral partition structure 202, causing it to deform. When the cylinder extension device 2032 retracts, the annular mesh 2034... 34. The elastic spiral partition structure 202 is moved away from the elastic spiral partition structure 202. The elastic spiral partition structure 202 recovers its deformation, so that the elastic spiral partition structure 202 can cooperate with the cylinder telescopic device 2032 to realize telescopic movement. The telescopic movement of the elastic spiral partition structure 202 can clean the inner wall of the reaction chamber container 100. Moreover, through the telescopic movement of the elastic spiral partition structure 202, the internal catalyst can be driven to shake or shift, breaking the static stacking state, significantly increasing the contact area between the feed gas and the active site of the catalyst, improving the mass transfer efficiency, and providing a higher quality feed gas for subsequent methanol synthesis.

[0039] Example 2: Refer to Figures 8-10 The shift reactor for producing green methanol from biomass feedstock includes a movable internal combined mesh structure 205, which consists of two mesh frames arranged in an alternating manner. This allows the mesh frames to slide, enabling the elastic spiral partition structure 202 to expand and contract smoothly. The movable internal combined mesh structure 205 can also intercept the catalyst, keeping it segmented and preserved. Furthermore, the movable internal combined mesh structure 205 has mesh openings to ensure spiral flow of the feedstock gas. Four catalyst discharge ports 101 are provided on one side of the shift reaction chamber container 100. By opening the corresponding catalyst discharge port 101, the catalyst to be replaced can be removed, facilitating segmented catalyst replacement. An airflow changing port 208 is provided on the shift path conveying cylinder structure 201, ensuring direct discharge of the feedstock gas and allowing for a change in the discharge path for rapid discharge of the feedstock gas.

[0040] The inner combined mesh sealing assembly 206 includes a sealing mesh layer 2061, which is installed on the mesh frame. The sealing mesh layer 2061 aligns with the mesh frame to ensure smooth flow of the raw material gas. When the sealing mesh layer 2061 is shifted, its mesh openings are misaligned with the mesh openings of the movable inner combined mesh structure 205, thus sealing the movable inner combined mesh structure 205 and allowing the raw material gas to smoothly pass through the airflow change port 208 to change its discharge path. Two transverse guide rails 2067 are fixedly connected to the mesh frame, guiding the sealing mesh layer 2061 so that it can slide smoothly on the transverse guide rails 2067 via transverse guide grooves 2068. The sealing mesh layer 2061 has two transverse guide grooves 2068, allowing it to slide smoothly along the transverse guide rails 2067. A longitudinal guide rail 2062 is fixedly connected to the sealing mesh layer 2061 on the transverse guide rail 2067. The longitudinal guide rail 2062 is slidably connected to the longitudinal guide slide rail 2063. The longitudinal guide slide rail 2063 can guide the longitudinal guide rail 2062, so that the longitudinal guide rail 2062 can slide smoothly up and down, thereby keeping the sealing mesh layer 2061 moving smoothly up and down, and allowing the elastic spiral partition structure 202 to maintain smooth expansion and contraction. A connector 2064 is fixedly connected to the longitudinal guide slide rail 2063. A guide slide rod 2065 is fixedly connected to one side of the connector 2064. The guide slide rod 2065 is sleeved in the guide slide sleeve 2066. The guide slide rod 2065 can slide smoothly in the guide slide sleeve 2066, so that the guide slide rod 2065 can drive the connector 2064 to move smoothly. The guide slide sleeve 2066 is fixedly installed on the changing path conveying cylinder structure 201.

[0041] The airflow path conversion assembly 207 includes a cylinder mounting base 2071, which is fixedly connected to the path conversion conveyor cylinder structure 201. A cylinder telescopic structure 2072 is fixedly installed on the cylinder mounting base 2071. The cylinder mounting base 2071 can fix the cylinder telescopic structure 2072, making the cylinder telescopic structure 2072 stable. The cylinder telescopic structure 2072 drives the support plate 2073 to move, causing the support plate 2073 to drive the sealing plate 2074 away from the airflow change port 208. This allows the airflow change port 208 to remain open. When the cylinder telescopic structure 2072 extends, the sealing plate 2074 can be smoothly embedded into the airflow change port 208, thereby maintaining the sealing of the changing path conveying cylinder structure 201. One end of the cylinder telescopic structure 2072 is fixedly connected to a support plate 2073. One side of the support plate 2073 is fixedly connected to two guide slide rods 2065. One side of the support plate 2073 is fixedly connected to a sealing plate 2074, which is disposed in the airflow change port 208.

[0042] In this embodiment: the cylinder telescopic structure 2072 drives the support plate 2073 to retract, causing the sealing plate 2074 to disengage from the airflow change port 208. At the same time, the support plate 2073 drives the guide slide rod 2065 to move. The guide slide rod 2065 drives the longitudinal guide slide rail 2063 to move through the connector 2064. The longitudinal guide slide rail 2063 drives the sealing mesh layer 2061 to move through the longitudinal guide rail 2062, so that the mesh of the sealing mesh layer 2061 is misaligned with the mesh of the movable inner combined mesh structure 205, maintaining a seal. At this time, the raw material gas can be directly discharged upward through the airflow change port 208 and the path changing conveyor structure 201. This method can select the path length according to the material to be processed, avoiding the problem of resource waste caused by a long path, thereby improving the operational flexibility of the equipment.

[0043] Example 3: Reference Figures 2-3 and Figures 5-7 A shift reactor for preparing green methanol from biomass feedstock includes an adjustable reaction mechanism 200. The adjustable reaction mechanism 200 includes a shift path conveying cylinder structure 201, which is fixedly connected in the shift reaction chamber container 100. An elastic spiral partition structure 202 is provided outside the shift path conveying cylinder structure 201. Two movable external combined mesh structures 204 are fixedly connected to the elastic spiral partition structure 202. Pressurizing components 203 are provided on both the upper and lower sides of the elastic spiral partition structure 202. The two pressurizing components 203 are connected to the two ends of the shift path conveying cylinder structure 201.

[0044] The internal structure of the path-changing conveying cylinder 201 is provided with an airflow path conversion component 207. The part of the airflow path conversion component 207 extending out of the path-changing conveying cylinder 201 is connected to two inner combined mesh sealing components 206. The two inner combined mesh sealing components 206 are respectively arranged on both sides of the movable inner combined mesh structure 205, and the movable inner combined mesh structure 205 is fixedly connected to the elastic spiral partition structure 202.

[0045] In this embodiment: the airflow path conversion component 207 opens the airflow change port 208, and the airflow path conversion component 207 drives the inner combined mesh sealing component 206 to close the movable inner combined mesh structure 205, so that the raw material gas is directly discharged through the airflow change port 208, avoiding resource waste caused by entering the upper part of the catalyst. Since the upper part of the raw material gas is in contact with the reaction later, it does not fully exert its activity. At this time, the catalyst is directly discharged by opening the lower catalyst discharge port 101, and the upper catalyst discharge port 101 is opened to collect the upper catalyst. This method can easily transfer the insufficiently consumed catalyst in the less frequently used upper part of the path to the lower part of the path, so that the catalyst can be reused in the area with higher reaction intensity, fully exert its activity potential, reduce resource waste caused by premature catalyst disposal, and facilitate catalyst separation, effectively reducing the frequency of catalyst procurement and replacement, and reducing costs.

[0046] Working principle: When preparing biomass raw materials, water gas is introduced through the lower inlet of the reaction chamber container 100, so that the water gas comes into contact with the catalyst to carry out the conversion reaction, and fully contacts the catalyst along the spiral shape of the elastic spiral partition structure 202 to carry out the reaction.

[0047] During the catalyst-water gas shift reaction, the cylinder extension device 2032 extends, which drives the annular ring 2033 to move. The annular ring 2033 then drives the annular mesh 2034 to move. The annular mesh 2034 applies pressure to the elastic spiral partition structure 202, causing it to deform. When the cylinder extension device 2032 retracts, the annular mesh 2034 moves away from the elastic spiral partition structure 202, allowing the elastic spiral partition structure 202 to recover its deformation. This causes the catalyst to move, thereby improving the mass transfer efficiency. The treated raw gas is discharged upward through the annular mesh 2034 and then discharged through the catalyst discharge port 101 above the shift reaction chamber container 100.

[0048] When the emission path needs to be switched, the cylinder telescopic structure 2072 retracts, causing the support plate 2073 to move. The support plate 2073 then causes the sealing plate 2074 to disengage from the airflow change port 208. The support plate 2073 also causes the guide slide rod 2065 to move, which in turn causes the connecting piece 2064 to move. The connecting piece 2064 moves the sealing mesh layer 2061 via the longitudinal guide slide rail 2063 and the longitudinal guide rail 2062, causing the mesh of the sealing mesh layer 2061 to be misaligned with the mesh of the movable inner combined mesh structure 205, thereby maintaining the seal of the movable inner combined mesh structure 205. At this time, the raw material gas, after passing through the catalyst in the lower part, can enter the airflow change port 208 and be discharged upward through the change path conveying cylinder structure 201.

[0049] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
