Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to an online carbon capture heat quality analysis testing system. Background Technology

[0002] Carbon capture refers to the process of reacting an adsorbent with carbon dioxide in a raw material (such as flue gas from a power plant) to adsorb and separate the carbon dioxide from the flue gas. Then, under certain conditions, the adsorbent is separated from the carbon dioxide in a reactor, thereby releasing the carbon dioxide. The carbon dioxide can then be purified and reused.

[0003] The patent application document with patent number CN114573258B discloses a material for carbon capture, its preparation method and application. Before the material is applied, a scenario simulation test needs to be conducted in the laboratory to verify the actual use effect through experimental data.

[0004] Existing carbon capture adsorbent materials exhibit significant temperature-dependent adsorption and desorption of carbon dioxide. To ensure experimental accuracy, temperature control of the materials is necessary. In most experiments, granular adsorbents are placed statically in quartz tubes and heated by an electric furnace. The experimental air flows from top to bottom through the quartz reaction tube to contact the adsorbents. However, due to mutual obstruction of the adsorbents, the contact is insufficient, leading to inaccurate quantities of adsorbents involved in adsorption and affecting experimental accuracy. To address this issue, we propose an online carbon capture thermal mass analysis and testing system. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing an online carbon capture heat quality analysis and testing system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An online carbon capture heat quality analysis and testing system includes a flue gas simulation component and an adsorption reactor, wherein the flue gas simulation component is connected to the adsorption reactor via a pipeline.

[0008] Flue gas simulation component: includes two gas tanks, two metering tube assemblies and a condensation separation tank. The two gas tanks respectively contain nitrogen and carbon dioxide. The metering tube assemblies are connected in series between the gas tanks and the adsorption reactor. The gas outlet of the adsorption reactor is connected to the GC analyzer through a pipeline.

[0009] Adsorption reactor: includes a heater and a reaction assembly, with the reaction assembly plugged into the middle of the heater;

[0010] The reaction assembly is provided with a gas distribution pipe, and a container for loading adsorbent is installed on the outside of the gas distribution pipe. The container includes a reversing shell and a mixing shell. A mesh ring is installed between the reversing shell and the mixing shell. Micropores are opened on the vertical side wall of the mixing shell, and an arc-shaped top is provided on the upper part of the mixing shell.

[0011] The heater is equipped with a heating plate and a heat-conducting ring. The heat-conducting ring is pressed and sleeved on the outside of the mixing shell. There is an air passage cavity between the heat-conducting rings that matches the micropores. A baffle is installed on the outside of the heat-conducting ring. The inner wall of the baffle has a vertically extending exhaust groove that communicates with the air passage cavity. An inner guide ring that fits and overlaps with the top of the arc is slidably installed on the inner wall of the heat-conducting ring.

[0012] The flue gas simulation component supplies simulated flue gas to the adsorption reactor through a metering tube assembly. The adsorbent material contained in the adsorption reactor adsorbs carbon dioxide from the simulated flue gas. The simulated flue gas can drive the adsorbent material to tumble and roll in the mixing shell to achieve full contact. The heater at the top of the arc provides efficient heating and temperature control for the adsorbent material inside, reducing the impact of temperature difference on adsorption. The exhaust gas after the adsorption reaction is directly guided to the GC analyzer for online analysis, reducing errors caused by exhaust gas delivery and enabling accurate detection of the carbon capture capacity of the adsorbent material.

[0013] Preferably, the gas distribution pipe includes a first combined pipe, a second combined pipe, and a third combined pipe connected vertically. The first combined pipe, the second combined pipe, and the third combined pipe have multiple independent air passages inside. The side walls of the first combined pipe, the second combined pipe, and the third combined pipe are respectively provided with a first air passage, a second air passage, and a third air passage corresponding to the air passages. The outer middle part of the first combined pipe, the second combined pipe, and the third combined pipe are each provided with a receiving box. The lower end opening of the upper reversing shell is fitted and sealed with the outer wall of the gas distribution pipe, and the bottom end of the lowermost reversing shell is closed.

[0014] The gas distribution pipe is divided into multiple sections. If two second combination pipes can be set, then a cross-shaped baffle inside the gas distribution pipe will divide the simulated flue gas into four parts, which will be matched with four receiving boxes. If the number of second combination pipes increases or decreases, the number of sides of the baffle can be changed to divide the simulated flue gas into the same number of parts as the number of combination pipes. The corresponding number of receiving boxes can be increased to divide the adsorbent material equally, which will greatly increase the adsorption space per unit volume of adsorbent material and further ensure that all adsorbent materials are in full contact with the simulated flue gas.

[0015] Preferably, a through hole is provided on the lower inner side of the mixing shell, and an annular slit is provided on the top of the through hole of the mixing shell. The opening of the annular slit is located above the mesh ring, and a diverting ring that cooperates with the through hole is installed at the bottom of the mixing shell.

[0016] The through-hole, combined with the annular slit, horizontally guides part of the flue gas flow into the mixing shell. This, combined with the vertically upward flue gas flow at the mesh ring position, applies an auxiliary driving force to the adsorbent material, causing it to be swept around the top of the arc, thus increasing the sweeping speed. It also blows the adsorbent material above the mesh ring to prevent blockage. Furthermore, the annular slit is positioned directly opposite the micropore, providing power for the flue gas to flow out of the mixing shell, ensuring smooth gas flow and preventing the pressure inside the mixing shell from rising, thereby ensuring stable test pressure.

[0017] Preferably, the inner wall at the lower edge of the mixing shell is screwed to the outer wall at the upper edge of the reversing shell by threads, and a pressure ring is press-fitted between the mixing shell and the reversing shell, with the pressure ring overlapping below the edge of the mesh ring;

[0018] The mixing shell and the reversing shell are connected by screws, allowing for quick separation. During separation, the mesh ring, which is pressed by the pressure ring, can move freely, facilitating the replacement of the adsorbent material.

[0019] Preferably, multiple gas distribution pipes are provided, and the gas distribution pipes are arranged in a ring array. The top of the heater is equipped with a gas distribution component that cooperates with the gas distribution pipe through a hinge. The gas outlet at the bottom of the gas distribution component is sealed and inserted into the top of the gas distribution pipe. The lower end of the heater is equipped with an exhaust shell corresponding to the gas distribution pipe. The inner wall of the exhaust shell is provided with an exhaust hole that cooperates with the exhaust groove.

[0020] The gas distribution assembly can be lifted upwards and backwards to disengage from the bottom of the gas distribution pipe, allowing the gas distribution pipe in the heater to be inserted and removed vertically. Because the inner guide ring and the heat-conducting ring slide and insert, the gas distribution pipe can be completely pulled out. Each gas distribution pipe can accommodate different types of adsorbent materials, allowing different types of adsorbent materials to be pre-installed in the heater. The adsorbent material installation is convenient. The gas distribution assembly guides the flue gas to different gas distribution pipes, allowing for the replacement of adsorbent materials without shutting down the system, reducing time and energy waste caused by changing test materials. The exhaust port and exhaust duct are positioned to ensure smooth airflow.

[0021] Preferably, the heating plate corresponds one-to-one with the gas distribution pipe, a liner is installed between adjacent heating plates, a heat insulation ring is sleeved on the outside of the heating plate, a shell is sleeved on the outside of the heat insulation ring, a rib is installed at the top of the inner guide ring, and the upper side wall of the rib slides and presses against the outer side wall of the gas distribution pipe.

[0022] The heating plates and gas distribution pipes are matched one-to-one, which can ensure that the gas distribution pipes are heated in one stage. The lining plate ensures the stability of the position between the heating plates, and the heat insulation ring can reduce heat loss and ensure stable temperature control. The outer shell is made of aluminum and is equipped with casters for easy movement. The ribs and gas distribution pipes slide and press against each other, and the simulated flue gas in the gas distribution pipes can be preheated by the heating plates to ensure the temperature stability of the adsorbent material.

[0023] Preferably, the air distribution assembly includes an air distribution duct, a butterfly valve is installed at the lower end of the air distribution duct, and a housing is installed on the outside of the air distribution duct and the butterfly valve;

[0024] The air distribution duct adopts a multi-manifold structure, with butterfly valves and air distribution ducts corresponding one-to-one. It can be used in conjunction with the opening and closing of butterfly valves to distribute simulated flue gas to different air distribution ducts, enabling quick control of adsorbent material replacement. The housing can ensure the stability of the air distribution duct and butterfly valve positions.

[0025] Preferably, the metering tube assembly includes a needle valve, a filter, a mass flow controller, a ball valve, and a check valve connected in series via a pipeline. The outlet of the check valve is connected to a gas distribution pipe, and a pressure gauge and a pressure sensor assembly are connected in series between the check valve and the gas distribution pipe.

[0026] The gas cylinder is pressurized by a needle valve, dusted by a filter, and the flow rate required for the reaction is controlled by a mass flow controller. Different concentrations of flue gas are simulated by using different ratios of nitrogen and carbon dioxide. A ball valve can be opened to ensure rapid gas flow, a check valve prevents gas backflow caused by pressure difference, and a pressure gauge and pressure sensor assembly can display the pressure inside the pipeline. The mass flow controller ensures the provision of accurate simulated flue gas, controls the variables in the experiment, and prevents inaccurate flue gas concentration from affecting the accuracy of the experiment.

[0027] Preferably, a thermocouple is installed through the side wall of the heater, and a temperature control instrument and a temperature display instrument are installed on the outer wall of the heater. The thermocouple is electrically connected to the temperature control instrument and the temperature display instrument through a data cable harness.

[0028] The temperature control instrument is connected to thermocouples and compensating wires via wires. The thermocouples and compensating wires are connected by quick connectors. The secondary instrument control system of Yudian is used as the temperature control instrument. The temperature signal collected by the thermocouple is transmitted back to the instrument. The instrument uses an advanced AI artificial intelligence PID regulation algorithm (proportional, integral, derivative) to control the temperature of the heating furnace. Yudian instrument also has a programmed temperature rise function, ensuring accurate temperature control. The temperature control instrument uses DCV input signal and DCV output, and has high measurement accuracy, fast thermal response time, robust durability, and good stability.

[0029] Preferably, a condensation separation tank is connected in series between the adsorption reactor and the GC analyzer. The top of the condensation separation tank is connected to the GC analyzer through a short pipe, and a drain valve is installed at the bottom of the condensation separation tank.

[0030] The reaction products are condensed by a condenser and then enter a condensation separator for gas-liquid separation. The separated gas phase is either vented through a vent valve or directed to a GC analyzer for online analysis. The liquid phase products can be discharged periodically through a drain valve to avoid affecting the detection accuracy of the GC analyzer.

[0031] Compared with existing technologies, the advantages of this online carbon capture heat quality analysis and testing system are as follows:

[0032] 1. Through the setting of the flue gas simulation component, nitrogen and carbon dioxide after depressurization are mixed and enter the adsorption reactor after the flow rate required for the reaction is controlled by the mass flow controller. The heating plate and temperature control instrument are used for one-stage precise temperature control. The heat is directly transferred to the mixing shell through the heat conduction ring and the inner guide ring. The adsorbent in the hoist is heated by the large-area arc top, and the flue gas in the gas distribution pipe is preheated by the fins to ensure the temperature stability during adsorption. The tail gas after the reaction is directly condensed and purified before entering the GC analyzer. The GC instrument and the adsorption reactor are integrated into the design, which reduces the length of the connecting pipeline, reduces tail gas loss, and greatly improves the gas detection performance.

[0033] 2. By setting up the reaction components, the flue gas is simulated to enter the multi-channel gas distribution pipe and come into contact with the adsorbent in multiple mixing shells in equal portions. This increases the mixing contact space and ensures the uniformity of contact between the adsorbent and the flue gas. The downward airflow is guided by the reversing shell to blow upward from the mesh ring, which, together with the arc top of the mixing shell, winds up the adsorbent. In addition, part of the airflow is distributed to the top of the annular slit to blow horizontally to the top of the mesh ring, so that the adsorbent below has a horizontal movement force. Combined with the upward airflow, the wind speed of the adsorbent is increased, which further improves the thoroughness of contact between the flue gas and the adsorbent, and the adsorbent is saturated with adsorption, ensuring the accuracy of the experiment.

[0034] 3. Through the design of the gas distribution assembly, before the experiment, the gas distribution assembly can be lifted upwards and backwards via a hinge to expose the gas distribution pipe below. The receiving boxes in multiple gas distribution pipes can each hold different adsorbent materials. After adding, the adsorbent flowing through the flue gas can be changed via a butterfly valve to conduct continuous experiments without stopping the machine. There is no need to cool down and replace the new adsorbent material, reducing the experimental time and energy costs. The gas distribution pipe and inner guide ring can be pulled out as a whole from the heat conduction ring. The separate gas distribution pipe and the outer receiving box can be quickly disassembled in sections. The threaded mixing shell and reversing shell can be quickly disassembled and the mesh ring removed for internal adsorbent replacement, improving the convenience of experimental preparation.

Detailed Implementation

[0044] 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.

[0045] Example 1

[0046] Reference Figure 13 and 8, an online carbon capture heat quality analysis and testing system, including a flue gas simulation component and an adsorption reactor 2. The flue gas simulation component is connected to the adsorption reactor 2 through a pipeline. The flue gas simulation component includes two gas tanks 1, two metering tube groups 12, and a condensation separation tank 16. The two gas tanks 1 respectively contain nitrogen and carbon dioxide. The metering tube groups 12 are connected in series between the gas tanks 1 and the adsorption reactor 2. The outlet of the adsorption reactor 2 is connected to a GC analyzer 17 through a pipeline. The adsorption reactor 2 includes a heater 22 and a reaction component 3. The reaction component 3 is inserted and installed in the middle of the heater 22. The reaction component 3 is provided with a gas distribution pipe 31, and a load of adsorbent is installed on the outside of the gas distribution pipe 31. The container for the agent includes a reversing shell 32 and a mixing shell 33. A mesh ring 35 is installed between the reversing shell 32 and the mixing shell 33. Microholes 331 are opened on the vertical side wall of the mixing shell 33, and an arc-shaped top 332 is provided on the upper part of the mixing shell 33. The heater 22 is provided with a heating plate 4 and a heat-conducting ring 42. The heat-conducting ring 42 is pressed and sleeved on the outside of the mixing shell 33. An air passage cavity 421 that cooperates with the microholes 331 is left between the heat-conducting rings 42. A baffle 41 is installed on the outside of the heat-conducting ring 42. A vertically extending exhaust groove 411 that communicates with the air passage cavity 421 is opened on the inner wall of the baffle 41. An inner guide ring 46 that fits and overlaps with the arc-shaped top 332 is slidably installed on the inner wall of the heat-conducting ring 42.

[0047] The flue gas simulation component supplies simulated flue gas to the adsorption reactor 2 via metering tube group 12. The adsorbent material contained in the adsorption reactor 2 adsorbs carbon dioxide in the simulated flue gas. The simulated flue gas can be redirected at the reversing shell 32, blowing upwards from the mesh ring 35, thereby causing the adsorbent material above the mesh ring 35 to float, achieving the function of an air flotation bed. Furthermore, the mixing shell 33 has an arc-shaped top 332 at its top. The adsorbent material pushed upwards can be rolled up under the guidance of the arc-shaped top 332 and fall back under the action of gravity. The air pressure of the simulated flue gas pushes the adsorbent material to roll and tumble in the mixing shell 33, achieving full gas-solid contact. The heater 22 conducts heat through the heat-conducting ring 42 in contact with the perimeter of the container, heating the adsorbent material in the mixing shell 33. Furthermore, an inner guide ring 46 is installed at the top of the arc 332 to increase the thermal contact area, enabling efficient heating and temperature control of the internally wound adsorbent material, reducing the impact of temperature difference on adsorption. Simulated flue gas entering the mixing shell 33 from the gas distribution pipe 31 will be discharged from the micropore 331, and then discharged downward through the gas passage 421 and exhaust duct 411. While the heat-conducting ring 42 heats the mixing shell 33, it does not affect the flow of simulated flue gas, preventing the internal pressure of the mixing shell 33 from rising and causing pressure changes that affect the test accuracy. The tail gas after the adsorption reaction is directly guided to the GC analyzer 17 for online analysis. There is no long delivery pipeline, and no need to collect it for further testing, reducing the error caused by tail gas delivery and enabling accurate detection of the carbon capture capacity of the adsorbent material.

[0048] Example 2

[0049] Reference Figure 2-7 An online carbon capture heat quality analysis and testing system includes a flue gas simulation component and an adsorption reactor 2. The flue gas simulation component is connected to the adsorption reactor 2 via a pipeline. The flue gas simulation component includes two gas tanks 1, two metering tube groups 12, and a condensation separation tank 16. The two gas tanks 1 respectively contain nitrogen and carbon dioxide. The metering tube groups 12 are connected in series between the gas tanks 1 and the adsorption reactor 2. The outlet of the adsorption reactor 2 is connected to a GC analyzer 17 via a pipeline. The adsorption reactor 2 includes a heater 22 and a reaction component 3. The reaction component 3 is inserted and installed in the middle of the heater 22. The reaction component 3 is provided with a gas distribution pipe 31, and a container loaded with adsorbent is installed on the outside of the gas distribution pipe 31. The housing includes a reversing shell 32 and a mixing shell 33. A mesh ring 35 is installed between the reversing shell 32 and the mixing shell 33. Microholes 331 are opened on the vertical side wall of the mixing shell 33, and an arc-shaped top 332 is provided on the upper part of the mixing shell 33. The heater 22 is provided with a heating plate 4 and a heat-conducting ring 42. The heat-conducting ring 42 is pressed and sleeved on the outside of the mixing shell 33. An air passage cavity 421 that cooperates with the microholes 331 is left between the heat-conducting rings 42. A baffle 41 is installed on the outside of the heat-conducting ring 42. A vertically extending exhaust groove 411 that communicates with the air passage cavity 421 is opened on the inner wall of the baffle 41. An inner guide ring 46 that fits and overlaps with the arc-shaped top 332 is slidably installed on the inner wall of the heat-conducting ring 42.

[0050] Specifically, the air distribution pipe 31 includes a first combined pipe 311, multiple second combined pipes 313 and a third combined pipe 315 connected vertically. The first combined pipe 311, the second combined pipe 313 and the third combined pipe 315 have multiple independent air passages inside. The side walls of the first combined pipe 311, the second combined pipe 313 and the third combined pipe 315 are respectively provided with a first air passage 312, a second air passage 314 and a third air passage 316 corresponding to the air passages. The outer middle part of the first combined pipe 311, the second combined pipe 313 and the third combined pipe 315 are respectively provided with a receiving box. The lower end opening of the upper reversing shell 32 is sealed with the outer wall of the air distribution pipe 31, and the bottom end of the lowermost reversing shell 32 is closed.

[0051] Furthermore, a through hole 334 is provided on the lower inner side of the mixing shell 33, and an annular slit 333 is provided at the top of the through hole 334. The opening of the annular slit 333 is located above the mesh ring 35, and a diverting ring 335 that cooperates with the through hole 334 is installed at the bottom of the mixing shell 33.

[0052] Furthermore, the inner wall of the lower edge of the mixing shell 33 is screwed to the outer wall of the upper edge of the reversing shell 32 by threads, and a pressure ring 351 is press-fitted between the mixing shell 33 and the reversing shell 32. The pressure ring 351 is overlapped and set below the edge of the mesh ring 35.

[0053] To further improve the uniformity of gas-solid contact, the gas distribution pipe 31 is divided into multiple segments. If two second combination pipes 313 can be set, then a cross-shaped baffle inside the gas distribution pipe 31 divides the simulated flue gas into four parts, which are then matched with four receiving boxes. If the number of second combination pipes 313 is increased or decreased, for example, if only one second combination pipe 313 is set, then the baffle can be triangular; if three second combination pipes 313 are set, then the baffle can be pentagonal, dividing the simulated flue gas into the same number of parts as the number of combination pipes, and correspondingly increasing the number of receiving boxes, the adsorbent material can be divided equally, significantly increasing the adsorption space per unit volume of adsorbent material, further ensuring that all adsorbent material is fully engaged with the simulated flue gas. The through-hole 334, combined with the annular slit 333, horizontally guides a portion of the flue gas flow into the mixing shell 33. This, combined with the vertically upward flue gas flow from the mesh ring 35, applies an auxiliary driving force to the adsorbent material, causing it to be wound around the top 332, increasing the winding speed and blowing away the adsorbent material above the mesh ring 35 to prevent blockage. The annular slit 333 is positioned directly opposite the micropore 331, providing power for the flue gas to exit the mixing shell 33, ensuring smooth gas flow and preventing pressure build-up within the mixing shell 33, thus maintaining stable test pressure. The mixing shell 33 and the reversing shell 32 are connected by screws, allowing for quick disassembly. During disassembly, the mesh ring 35, pressed by the pressure ring 351, can move freely, facilitating easy replacement of the adsorbent material.

[0055] Reference Figure 3 6 and 7, an online carbon capture heat quality analysis and testing system, including a flue gas simulation component and an adsorption reactor 2. The flue gas simulation component is connected to the adsorption reactor 2 through a pipeline. The flue gas simulation component includes two gas tanks 1, two metering tube groups 12, and a condensation separation tank 16. The two gas tanks 1 respectively contain nitrogen and carbon dioxide. The metering tube groups 12 are connected in series between the gas tanks 1 and the adsorption reactor 2. The outlet of the adsorption reactor 2 is connected to a GC analyzer 17 through a pipeline. The adsorption reactor 2 includes a heater 22 and a reaction component 3. The reaction component 3 is inserted and installed in the middle of the heater 22. The reaction component 3 is provided with a gas distribution pipe 31, and a load of adsorbent is installed on the outside of the gas distribution pipe 31. The container for the agent includes a reversing shell 32 and a mixing shell 33. A mesh ring 35 is installed between the reversing shell 32 and the mixing shell 33. Microholes 331 are opened on the vertical side wall of the mixing shell 33, and an arc-shaped top 332 is provided on the upper part of the mixing shell 33. The heater 22 is provided with a heating plate 4 and a heat-conducting ring 42. The heat-conducting ring 42 is pressed and sleeved on the outside of the mixing shell 33. An air passage cavity 421 that cooperates with the microholes 331 is left between the heat-conducting rings 42. A baffle 41 is installed on the outside of the heat-conducting ring 42. A vertically extending exhaust groove 411 that communicates with the air passage cavity 421 is opened on the inner wall of the baffle 41. An inner guide ring 46 that fits and overlaps with the arc-shaped top 332 is slidably installed on the inner wall of the heat-conducting ring 42.

[0056] Specifically, multiple gas distribution pipes 31 are provided, arranged in a ring array. The top of the heater 22 is fitted with a gas distribution component 21 that cooperates with the gas distribution pipe 31 via a hinge. The bottom outlet of the gas distribution component 21 is sealed and plugged into the top of the gas distribution pipe 31. The lower end of the heater 22 is fitted with an exhaust shell 23 corresponding to the gas distribution pipe 31. The inner wall of the exhaust shell 23 is provided with an exhaust hole 231 that cooperates with the exhaust groove 411.

[0057] It is worth noting that the heating plate 4 corresponds one-to-one with the gas distribution pipe 31. A liner 43 is installed between adjacent heating plates 4. A heat insulation ring 44 is installed on the outside of the heating plate 4. A shell 45 is installed on the outside of the heat insulation ring 44. A rib 461 is installed at the top of the inner guide ring 46. The upper side wall of the rib 461 slides and presses against the outer side wall of the gas distribution pipe 31.

[0058] It is worth noting that the air distribution assembly 21 includes an air distribution duct 212, a butterfly valve 213 is installed at the lower end of the air distribution duct 212, and a housing 211 is installed on the outside of the air distribution duct 212 and the butterfly valve 213.

[0059] To provide the capability for non-stop switching tests using various adsorbent materials, the gas distribution assembly 21 can be lifted upwards and backwards to disengage from the bottom of the gas distribution pipe 31. This allows the gas distribution pipe 31 in the heater 22 to be easily inserted and removed. Because the inner guide ring 46 and the heat-conducting ring 42 are slidably connected, the gas distribution pipe 31 can be completely pulled out. Each gas distribution pipe 31 can accommodate different types of adsorbent materials, allowing for pre-installation of different types of adsorbent materials in the heater 22. The installation of adsorbent materials is convenient. The gas distribution assembly 21 guides the flue gas into different gas distribution pipes 31, enabling non-stop replacement of adsorbent materials and reducing time and energy waste caused by changing test materials. The exhaust port 231 corresponds to the exhaust duct 411, ensuring smooth airflow. The heating plate 4 corresponds one-to-one with the gas distribution pipe 31, which can ensure that the gas distribution pipe 31 is heated in one stage. The liner 43 ensures the stability of the position between the heating plates 4. The heat insulation ring 44 can reduce heat loss and ensure stable temperature control. The outer shell 45 adopts an aluminum structure and is equipped with casters for easy movement. The ribs 461 slide and press against the gas distribution pipe 31, which can preheat the simulated flue gas in the gas distribution pipe 31 through the heating plate 4 to ensure the temperature stability of the adsorbent material. The air distribution pipe 212 adopts a multi-manifold structure. The butterfly valve 213 corresponds one-to-one with the gas distribution pipe 31. It can be used to distribute the simulated flue gas to different gas distribution pipes 31 in conjunction with the opening and closing of the butterfly valve 213, so as to quickly control the replacement of the adsorbent material. The shell 211 can ensure the stability of the position of the air distribution pipe 212 and the butterfly valve 213.

[0061] Reference Figure 1 , 23. An online carbon capture heat quality analysis and testing system includes a flue gas simulation component and an adsorption reactor 2. The flue gas simulation component is connected to the adsorption reactor 2 via a pipeline. The flue gas simulation component includes two gas tanks 1, two metering tube groups 12, and a condensation separation tank 16. The two gas tanks 1 respectively contain nitrogen and carbon dioxide. The metering tube groups 12 are connected in series between the gas tanks 1 and the adsorption reactor 2. The outlet of the adsorption reactor 2 is connected to a GC analyzer 17 via a pipeline. The adsorption reactor 2 includes a heater 22 and a reaction component 3. The reaction component 3 is inserted and installed in the middle of the heater 22. The reaction component 3 is provided with a gas distribution pipe 31, and a container loaded with adsorbent is installed on the outside of the gas distribution pipe 31. The housing includes a reversing shell 32 and a mixing shell 33. A mesh ring 35 is installed between the reversing shell 32 and the mixing shell 33. Microholes 331 are opened on the vertical side wall of the mixing shell 33, and an arc-shaped top 332 is provided on the upper part of the mixing shell 33. The heater 22 is provided with a heating plate 4 and a heat-conducting ring 42. The heat-conducting ring 42 is pressed and sleeved on the outside of the mixing shell 33. An air passage cavity 421 that cooperates with the microholes 331 is left between the heat-conducting rings 42. A baffle 41 is installed on the outside of the heat-conducting ring 42. A vertically extending exhaust groove 411 that communicates with the air passage cavity 421 is opened on the inner wall of the baffle 41. An inner guide ring 46 that fits and overlaps with the arc-shaped top 332 is slidably installed on the inner wall of the heat-conducting ring 42.

[0062] Specifically, the metering assembly 12 includes a needle valve 121, a filter 122, a mass flow controller 123, a ball valve 124, and a check valve 125 connected in series via pipes. The outlet of the check valve 125 is connected to the gas distribution pipe 31. A pressure gauge and a pressure sensor assembly 13 are connected in series between the check valve 12 and the gas distribution pipe 31.

[0063] Furthermore, a thermocouple is installed through the side wall of the heater 22, and a temperature control instrument 14 and a temperature display instrument 15 are installed on the outer wall of the heater 22. The thermocouple is electrically connected to the temperature control instrument 14 and the temperature display instrument 15 through a data cable harness.

[0064] Furthermore, a condensation separation tank 16 is connected in series between the adsorption reactor 2 and the GC analyzer 17. The top of the condensation separation tank 16 is connected to the GC analyzer 17 through a short pipe, and a drain valve 18 is installed at the bottom of the condensation separation tank 16.

[0065] To ensure the accuracy of experimental data acquisition, gas tank 1 is pressurized via needle valve 121, dust is removed via filter 122, and the flow rate required for the reaction is controlled by mass flow controller 123. Different concentrations of flue gas are simulated by varying the ratio of nitrogen and carbon dioxide. Ball valve 124 can be opened to ensure rapid gas flow, and check valve 125 prevents backflow due to pressure difference. Pressure gauge and pressure sensor assembly 13 can display the pressure inside the pipeline. Mass flow controller 123 ensures accurate simulated flue gas supply, controls experimental variables, and prevents inaccurate flue gas concentration from affecting experimental accuracy. Temperature control instrument 14 is connected to thermocouples and compensating wires via wires. The thermocouples and compensating wires have quick-connect couplings. Yudian's secondary instrument control system is used as the temperature control instrument 14. The temperature data collected by the thermocouples... The temperature signal is transmitted back to the instrument, which uses an advanced AI artificial intelligence PID regulation algorithm (proportional, integral, derivative) to control the temperature of the heating furnace. Yudian Instrument also has a programmed heating function, ensuring accurate temperature control. The temperature control instrument 14 uses a DC5V input signal and a DC5V output, enabling real-time monitoring of each controlled parameter. It will first sound an alarm when an abnormality is detected, and if the fault develops further, it will trigger an interlock action, such as cutting off the heating. It has high measurement accuracy, fast thermal response time, robustness, durability, and good stability. The reaction products are condensed by the condenser and then enter the condensation separation tank 16 for gas-liquid separation. The separated gas phase is vented through the vent valve or guided to the GC analyzer 17 for online analysis. The liquid phase products can be discharged periodically through the drain valve 18 to avoid affecting the detection accuracy of the GC analyzer 17.
