Description

Technical Field

[0001] The invention belongs to the technical field of catalyst synthesis screening, and in particular relates to an infrared thermal imaging multi-channel catalyst screening and evaluation device. Background Art

[0002] Catalysts play a vital role in inorganic chemistry, petroleum, organic chemistry, coal chemistry, and polymer chemistry. Their research and development is a core issue in the modern chemical industry. Currently, industrial catalysts are still developed using a trial-and-error approach, with the average lead time from research and development to commercialization being as long as 18 years, far behind production requirements. Integrating materials genomics with catalyst and catalytic research is a key approach to addressing this lag in the development cycle for modern industrial catalysts.

[0003] Due to the severe global oil reserve shortage and even more serious environmental problems caused by excessive oil exploitation and utilization, iron-based catalysts that produce synthesis gas from non-petroleum carbon resources such as natural gas, coal, and biomass, and then convert it into liquid fuels and chemical feedstocks through Fischer-Tropsch synthesis, have attracted widespread attention. Traditional iron-based catalyst preparation methods are inefficient, require long processing times, and are unable to quickly and effectively screen for high-performance catalysts. Therefore, in the exploration of catalysts for producing liquid fuels from non-petroleum carbon resources, it is crucial to find methods that can improve catalyst synthesis efficiency, shorten experimental cycles, and rapidly characterize reaction performance.

[0004] Multi-channel parallel synthesis allows for the rapid synthesis of a large number of different catalytic materials in a limited number of steps in a short period of time, forming a material library. Combined with corresponding high-throughput screening techniques, this allows for high-throughput characterization of this catalyst library. This combination of methods accelerates the exploration of new catalysts and screens for the best performing catalysts. However, catalytic reaction systems are complex, with diverse catalyst components, structures, and functions, all requiring varying preparation conditions. Therefore, it is necessary to develop feasible and efficient parallel synthesis and high-throughput characterization methods tailored to the characteristics and reaction properties of different catalysts.

[0005] Chinese patent CN202410622U discloses a multi-channel high-throughput catalyst evaluation device, which includes a feeding system, a reaction system, a cooling system, a sampling and analysis system, and a product collection system. The catalyst is loaded into the reactor, and the raw materials enter the mixing unit through the flow control unit for uniform mixing, and then enter the multi-channel reactor for reaction; after the reaction is completed, the material enters the next unit after cooling, and is sampled and analyzed by the sampling and analysis system, while the material is sent to the product collection system; the product is separated into gas and liquid in the high-pressure separator, the liquid phase enters the product storage unit for storage, and the gas phase is collected or vented through the gas path for related processing. This utility model is suitable for simultaneously evaluating multiple catalysts at the same reaction temperature and the same reaction pressure, significantly improving the efficiency of screening catalysts, saving test time, and having good test repeatability.

[0006] However, the patent makes the device structure complicated by setting up multiple reactors to achieve multi-channel reaction, and the method of analyzing the products is relatively traditional and the screening efficiency is not substantially improved. At the same time, the complexity of the experiment increases the difficulty of the operator. For this reason, we propose an infrared thermal imaging multi-channel catalyst screening and evaluation device to solve the problems existing in the existing technology, so that it improves the screening efficiency of Fischer-Tropsch synthesis catalysts, shortens the catalyst development cycle, and at the same time improves the uniformity of catalyst heating during the heating process. Each channel is independently set and will not affect each other. Summary of the Invention

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] The present invention provides Figures 1-9An infrared thermal imaging multi-channel catalyst screening and evaluation device shown includes a base 1, an openable high-pressure cover 2 is installed on the top of the base 1, the top of the high-pressure cover 2 and the side located on the infrared window 4 are connected to an air intake pipe 32, the bottom of the base 1 and the side located on the heating platform 8 are connected to an exhaust pipe 33, handles 34 are fixedly installed on both sides of the high-pressure cover 2, and a sealing assembly for fixing the high-pressure cover 2 to the top of the base 1 is also installed on the surface of the base 1, the sealing assembly includes a sealing groove 18 opened on the top of the base 1, the bottom of the high-pressure cover 2 is clamped with the inner cavity of the sealing groove 18, the bottom of the inner cavity of the sealing groove 18 is clamped with a sealing ring 19, the bottom of the high-pressure cover 2 is fitted with the top of the sealing ring 19, and locking rods 20 are threadedly connected on both sides of the base 1, one end of the locking rod 20 passes through the base 1 and extends to the inner cavity of the sealing groove 18 and fits with the surface of the high-pressure cover 2.

[0039] By cooperating with the air inlet pipe 32 and the exhaust pipe 33, the reaction gas can be introduced into the high-pressure cover 2 through the air inlet pipe 32 and discharged to the outside through the exhaust pipe 33, so as to realize air circulation in the high-pressure cover 2. The setting of the handle 34 can facilitate the user to move the high-pressure cover 2 to the working height. By setting the sealing assembly, the high-pressure cover 2 can be installed and fixed on the top of the base 1.

[0040] When installing the high-pressure cover 2, the user can insert the bottom of the high-pressure cover 2 into the sealing groove 18 at the top of the base 1. At this time, the bottom of the high-pressure cover 2 fits with the top of the sealing ring 19, and the sealing ring 19 can seal the connection between the high-pressure cover 2 and the sealing groove 18. Then the user can tighten the locking rod 20. The rotation of the locking rod 20 will cause one end of the locking rod 20 to penetrate the base 1 and extend to the inner cavity of the sealing groove 18 and fit with the surface of the high-pressure cover 2, thereby installing and fixing the high-pressure cover 2 in the use position.

[0041] Preferably, a gantry 3 is installed on the surface of the base 1, and a sliding connection assembly is provided between the high-pressure cover 2 and the gantry 3. The high-pressure cover 2 is slidingly connected to the inner cavity of the gantry 3 through the sliding connection assembly. The sliding connection assembly includes a sliding sleeve 13 fixedly installed on both sides of the high-pressure cover 2, and the inner wall of the sliding sleeve 13 is slidingly connected to the surface of the gantry 3. Limiting rods 14 are fixedly installed on both sides of the inner cavity of the sliding sleeve 13. A limiting groove 15 adapted to the limiting rod 14 is opened on the surface of the gantry 3, and the surface of the limiting rod 14 is slidingly connected to the inner wall of the limiting groove 15.

[0042] By setting up the sliding connection component, the stability of the movement of the high-pressure cover 2 can be improved. When opening the high-pressure cover 2, the user can pull the high-pressure cover 2 upward through the handle 34. The movement of the high-pressure cover 2 will drive the sliding sleeve 13 to slide on the surface of the gantry 3. By cooperating with the limiting rod 14 and the limiting groove 15, the stability of the movement of the sliding sleeve 13 can be improved, and the sliding sleeve 13 can be prevented from being offset during movement and causing its inner wall to be stuck with the surface of the gantry 3. When moving, the sliding sleeve 13 will drive the limiting rod 14 to slide in the inner cavity of the limiting groove 15.

[0043] Among them, the sliding connection assembly is also equipped with a positioning assembly for fixing the adjustment position of the high-pressure cover 2. The positioning assembly includes a positioning tube 16 fixedly installed on one side of the sliding sleeve 13. One end of the positioning tube 16 is threadedly connected to a positioning rod 17. One end of the positioning rod 17 passes through the positioning tube 16 and the sliding sleeve 13 in sequence and extends to the inner cavity of the sliding sleeve 13 to fit the surface of the gantry 3.

[0044] Through the setting of the positioning component, after the high-pressure hood 2 is adjusted to its operating height, the user can tighten the positioning rod 17. The rotation of the positioning rod 17 will cause one end of the positioning rod 17 to pass through the positioning tube 16 and the sliding sleeve 13 in sequence and extend to the inner cavity of the sliding sleeve 13 to fit with the surface of the gantry 3, thereby locking the position of the high-pressure hood 2.

[0045] Furthermore, an infrared window 4 is provided on the top of the high-pressure cover 2, and a zinc selenide lens 5 is fixedly connected to the inner cavity of the infrared window 4. An infrared thermal imaging camera 7 is provided in the inner cavity of the gantry 3. A heating platform 8 is installed on the top of the base 1, and a heating plate 9 is fixedly installed on the top of the heating platform 8. A multi-channel reaction pool 10 is provided on the top of the heating platform 8 and outside the heating plate 9. Several groups of quartz-lined reaction channels 11 are installed on the top of the multi-channel reaction pool 10, and the number of quartz-lined reaction channels 11 is 9-100. A heating chamber 12 is provided at the bottom of the multi-channel reaction pool 10.

[0046] By using the infrared thermal imaging camera 7, the multi-channel reaction cell 10, and the heating stage 8 in conjunction, when screening catalysts, the user can add the various catalysts synthesized in parallel in the multi-channel to the quartz-lined reaction channel 11, place the material library in, install the high-pressure cover 2, and then install the infrared thermal imaging camera 7 through the adjustment component. The reaction gas is introduced into the high-pressure cover 2 from the air inlet pipe 32, and the pressure is raised to the specified level and heated to the target temperature. The infrared thermal imaging camera 7 is then used to take photos at different times.

[0047] During heating, the heating table 8 transfers heat to the heating chamber 12 through the heating plate 9. Since the outer surfaces of the quartz-lined reaction channels 11 are located in the inner cavity of the heating chamber 12, the heating area of ​​the quartz-lined reaction channels 11 can be increased, so that the catalyst inside the quartz-lined reaction channels 11 can be heated evenly. Moreover, each quartz-lined reaction channel 11 is independently arranged, and there is no problem of heat interference inside each quartz-lined reaction channel 11, which improves the accuracy of infrared detection.

[0048] Because different catalytic materials have varying catalytic abilities and react with varying amounts of heat, the surface temperature of each catalyst can vary slightly. Using temperature-sensitive infrared photography, these changes in catalyst surface temperature can be recorded, enabling catalyst screening. The heat release of each catalyst in the infrared thermal images obtained is determined by the color of each point in the image. The redder the color, the more pronounced the heat release and the stronger the catalytic ability.

[0049] Furthermore, the bottom end of the quartz lined reaction channel 11 passes through the multi-channel reaction pool 10 and extends to the inner cavity of the heating chamber 12. The inner cavity of the heating chamber 12 is installed with a fixing seat 39. The surface of the fixing seat 39 is provided with a fixing groove 40. The inner cavity of the fixing groove 40 is fixedly installed with a mounting tube 41. The inner cavity of the mounting tube 41 is provided with an asbestos mesh layer 42. The inner ring of the asbestos mesh layer 42 is in contact with the outer surface of the quartz lined reaction channel 11. The bottom of the quartz lined reaction channel 11 is fixedly installed. A connecting shell 43 is provided, and the inner cavity of the connecting shell 43 is rotatably connected to a tube body 44. A fan blade 45 is fixedly installed at one end of the tube body 44 located in the inner cavity of the connecting shell 43. The end of the tube body 44 away from the fan blade 45 passes through the quartz-lined reaction channel 11 and extends to the inner cavity of the quartz-lined reaction channel 11. A stirring blade 46 is installed on the surface of the tube body 44 and located in the inner cavity of the quartz-lined reaction channel 11. A ventilation groove 47 is provided on the surface of the tube body 44 and located in the inner cavity of the connecting shell 43.

[0050] By using the fixing base 39 and the mounting tube 41 in combination, the quartz lined reaction channels 11 can be separated to achieve the purpose of preventing the reactions of the quartz lined reaction channels 11 from interfering with each other;

[0051] At the same time, through the coordinated use of the fan blades 45, the tube body 44 and the ventilation grooves 47, as the temperature inside the heating chamber 12 continues to rise, and as the temperature rises, the pressure inside the heating chamber 12 gradually increases, and at the same time, the temperature difference between the inside of the heating chamber 12 and the inner cavity of the high-pressure cover 2 is large, under the action of the temperature difference and the pressure difference, the air inside the heating chamber will flow into the inner cavity of the high-pressure cover 2 through the ventilation grooves 47 and the tube body 44, and the air flow will drive the fan blades 45 to rotate, and then drive the stirring blades 46 to rotate through the tube body 44, stirring the catalyst inside the quartz-lined reaction channel 11 to improve its heating uniformity;

[0052] It should be noted that there is a certain gap between the snap-on shell 36 and the multi-channel reaction pool 10. As the air inside the heating chamber 12 is continuously discharged to the outside, the air inside the high-pressure cover 2 will enter the inner cavity of the heating chamber 12 through the gap between the snap-on shell 36 and the multi-channel reaction pool 10, thereby achieving the purpose of air circulation.

[0053] Moreover, when the air inside the heating chamber 12 passes through the tube body 44, the catalyst inside the quartz-lined reaction channel 11 can be heated through the tube body 44. The dual heating inside and outside can achieve the purpose of rapid heating. At the same time, through the setting of the asbestos mesh layer 42, the asbestos mesh layer 42 is made of iron wire and asbestos. The thermal conductivity of the iron wire is very good. Since the iron wire mesh is very uniform, the iron wire can quickly and evenly transfer the absorbed heat to the heated object during heating.

[0054] Furthermore, a support ring 48 is rotatably connected to the surface of the tube body 44 and located in the inner cavity of the quartz-lined reaction channel 11, and a support rod 49 is fixedly connected to the surface of the support ring 48. The end of the support rod 49 away from the support ring 48 is fixedly connected to the inner wall of the quartz-lined reaction channel 11.

[0055] By using the support ring 48 and the support rod 49 in combination, a support effect can be provided for one end of the tube body 44 located inside the quartz-lined reaction channel 11 to improve the rotation stability of the tube body 44. When the tube body 44 rotates, its surface will be rotatably connected to the inner wall of the support ring 48, and the support ring 48 is installed and fixed on the inner wall of the quartz-lined reaction channel 11 through the support rod 49.

[0056] It is worth noting that a protective cover 6 for protecting the zinc selenide lens 5 is also provided on the top of the infrared window 4. One side of the protective cover 6 is movably connected to the top of the high-voltage cover 2 through a hinge assembly. The hinge assembly includes a hinge frame 21 fixedly mounted on one side of the protective cover 6. A bracket 22 is fixedly mounted on the top of the high-voltage cover 2 and located corresponding to the hinge frame 21. One side of the hinge frame 21 is rotatably connected to the top of the bracket 22. The other side of the protective cover 6 is magnetically fixed to the top of the high-voltage cover 2 through a magnetic assembly. The magnetic assembly includes a magnetic plate 23 fixedly mounted on the other side of the protective cover 6. A first magnet plate 24 is embedded in the bottom of the magnetic plate 23. A second magnet plate 25 is embedded in the top of the high-voltage cover 2 and located corresponding to the first magnet plate 24. The bottom of the first magnet plate 24 and the top of the second magnet plate 25 are magnetically attracted together.

[0057] By setting the protective cover 6, the zinc selenide lens 5 can be protected. By setting the zinc selenide lens 5, sufficient infrared light can be ensured to pass through. After using the device, the user can cover the protective cover 6 to protect the zinc selenide lens 5. When moving the protective cover 6, the movement of the protective cover 6 will drive the hinged frame 21 to rotate on the surface of the bracket 22. When the protective cover 6 is tightly covered on the top of the infrared window 4, the magnetic plate 23 on the other side of the protective cover 6 will fit together with the top of the high-voltage cover 2. At this time, the first magnet plate 24 will be magnetically attracted to the second magnet plate 25, thereby magnetically positioning the protective cover 6 to improve the stability of the protective cover 6 when used.

[0058] Furthermore, the infrared thermal imaging camera 7 is installed together with the gantry 3 through an adjustable height adjustment component. The adjustment component includes an adjustment tube 26 embedded in the top of the gantry 3. The inner cavity of the adjustment tube 26 is slidably connected to an adjustment rod 27. The surface of the adjustment rod 27 is engraved with scale lines 28. The bottom end of the adjustment rod 27 passes through the adjustment tube 26 and the gantry 3 in sequence and extends to the inner cavity of the gantry 3. One side of the adjustment tube 26 is threadedly connected to a fixing rod 29. One end of the fixing rod 29 passes through the adjustment tube 26 and extends to the inner cavity of the adjustment tube 26 and fits the surface of the adjustment rod 27.

[0059] By setting the adjustment component, the operating height of the infrared thermal imaging camera 7 can be adjusted. During adjustment, the user can directly adjust the operating height of the infrared thermal imaging camera 7 by pulling the adjustment rod 27. The user can judge the operating height of the infrared thermal imaging camera 7 by the scale line 28 on the surface of the adjustment rod 27. After adjusting the operating height, the user can tighten the fixing rod 29. The rotation of the fixing rod 29 will cause the adjustment tube 26 at one end to extend until the inner cavity of the adjustment tube 26 is in contact with the surface of the adjustment rod 27, thereby locking and fixing the operating height of the infrared thermal imaging camera 7.

[0060] Preferably, the bottom end of the adjusting rod 27 is connected to the infrared thermal imaging camera 7 through a mounting assembly, and the mounting assembly includes a mounting screw 30 fixedly mounted on the bottom end of the adjusting rod 27. The top of the infrared thermal imaging camera 7 is provided with a mounting screw hole 31 adapted to the mounting screw 30, and the bottom end of the mounting screw 30 is threadedly connected to the inner wall of the mounting screw hole 31.

[0061] By setting up the mounting assembly, the infrared thermal imaging camera 7 can be mounted on the bottom end of the adjusting rod 27. During installation, the user can move the infrared thermal imaging camera 7 to the bottom end of the adjusting rod 27 and align the mounting screw hole 31 with the mounting screw 30. The user can then twist the infrared thermal imaging camera 7 to tighten the mounting screw 30 into the inner cavity of the mounting screw hole 31, thereby achieving the purpose of mounting the infrared thermal imaging camera 7 and the adjusting rod 27 together. Installing the infrared thermal imaging camera 7 by means of a threaded connection can facilitate disassembly and maintenance by the user.

[0062] It is worth noting that the multi-channel reaction pool 10 and the heating platform 8 are fixed together by a snap-on assembly. The snap-on assembly includes elastic snaps 35 fixedly installed on both sides of the multi-channel reaction pool 10. A snap-on shell 36 is fixedly installed on the top of the heating platform 8 and at the corresponding position of the multi-channel reaction pool 10. The surface of the snap-on shell 36 is provided with a slot 37 adapted to the elastic snap 35. The snap-on end of the elastic snap 35 is snapped with the inner wall of the slot 37. An insertion slot 38 is provided on the inner wall of the snap-on shell 36 and directly above the slot 37. The surface of the elastic snap 35 is slidably connected to the inner wall of the insertion slot 38.

[0063] By setting the snap-fit ​​assembly, the multi-channel reaction pool 10 can be installed and fixed on the top of the heating table 8. During installation, the user can press the multi-channel reaction pool 10 in the direction of the snap-fit ​​shell 36. The movement of the multi-channel reaction pool 10 will drive the elastic snaps 35 on both sides to slide in the inner cavity of the insertion slot 38. When the multi-channel reaction pool 10 is fully inserted into the inner cavity of the snap-fit ​​shell 36, the pop-up end of the elastic snap 35 will move to the corresponding position of the slot 37 and pop out to be connected to the inner cavity of the slot 37, thereby achieving the purpose of snap-fitting and fixing the use position of the multi-channel reaction pool 10.

[0064] Example 2

[0065] The difference from Example 1 is that in Example 2, the fan blades 45 are equipped with an external drive. Referring to the electric fan structure, a drive motor (not shown) is provided on the fan blades 45. Since the temperature and pressure in the inner cavity of the heating chamber 12 gradually increase with the heating process of the heating table 8, before the temperature and air pressure inside the heating chamber 12 reach a level that can drive the fan blades 45 to rotate, the fan blades 45 are driven by the external drive to rotate, so as to realize that the rotation of the fan blades 45 drives the tube body 44 and the stirring blades 46 to rotate, and stir the catalyst inside the quartz-lined reaction channel 11 to improve its heating uniformity; when the temperature and air pressure inside the heating chamber 12 reach a level that can drive the fan blades 45 to rotate, the external drive can be cut off, and the high temperature and high pressure can be used to drive the air circulation to drive the fan blades 45 to rotate. In this embodiment, the fan blades 45 have two driving modes, which can adapt to the driving requirements of the fan blades 45 at different stages during the detection process.
