Description

Technical Field

[0002] Reformer, i.e. reforming reactor, refers to equipment used for catalytic reforming. With the continuous development of hydrogen energy related technologies, reforming hydrogen production technology has attracted more and more attention. However, there is currently no complete reformer testing system in the field of reforming hydrogen production. Among them, according to the analysis of the inventor, there are at least two problems as follows:

Currently, there is no test method or system with high universality.

[0004] Second, the existing reformer test system is generally only aimed at testing the reforming path of one reformer.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0041] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0042] Example 1

[0043] like Figures 1 to 8 As shown, this embodiment provides a reformer test system 100, including a raw material supply module 1, a water vapor supply module 2, a reforming reaction module 3 and a gas analysis module 4. The raw material supply module 1 includes a first gas fuel supply module 11 and a liquid fuel supply module 12, and the first gas fuel supply module 11 and the liquid fuel supply module 12 can be connected to the inlet of the reforming reaction module 3 respectively; the water vapor supply module 2 can be connected to the inlet of the reforming reaction module 3; the reforming reaction module 3 is used to perform a reforming reaction; the gas analysis module 4 is connected to the gas outlet of the reforming reaction module 3 for analyzing the tail gas of the reforming reaction module 3. Among them, the first gas fuel supply module 11 includes a main pipeline 111 and a plurality of first branch pipelines 112, one end of the plurality of first branch pipelines 112 is connected to the main pipeline 111, the main pipeline 111 can be connected to the reforming reaction module 3, and the plurality of first branch pipelines 112 correspond to different raw gas sources respectively.

[0044] Through the above-mentioned technical scheme, on the one hand, in the reformer test system 100 of the present application, the raw material supply module 1 includes a gas fuel supply module and a liquid fuel supply module 12 which can be connected to the reforming reaction module 3. In this way, the operator can switch the type of raw materials supplied according to the test needs to adapt to the testing needs of different reforming paths, and thus can have a high universality for the testing needs of different reforming paths.

[0045] On the other hand, when faced with the need to test different reforming paths (for example, partial oxidation reforming, autothermal reforming, and carbon dioxide dry reforming, etc.), the required raw materials can be quickly and efficiently switched through the first branch pipeline 112, which can effectively reduce the operational difficulty of switching and improve testing efficiency.

[0046] In this embodiment, it should be noted that

[0047] The quantity and type of the raw gas source of the present application can be adjusted according to the test needs, for example, Figure 2 and Figure 3As shown, the type of raw gas source can be set to hydrogen, methane, carbon monoxide, carbon dioxide and oxygen, etc. Correspondingly, the first branch pipeline 112 can be set to the number corresponding to the type of raw gas source, and this application does not make specific limitations on this.

[0048] In addition, it should be noted that in order to improve safety, the raw gas source corresponding to a first branch pipeline 112 can also be set to nitrogen, which is mainly used for pipeline purging to prevent the raw gas from reacting in the pipeline before entering the reformer. Or, in an emergency, nitrogen can be used to blow the raw gas in all pipelines out of the pipeline, reformer and other equipment or structures to avoid danger.

[0049] In one embodiment of the present application, Figure 2 and Figure 3 As shown, the multiple first branch pipes 112 of the present application can respectively correspond to any one of the hydrogen gas source, the nitrogen gas source, the methane gas source, the carbon monoxide gas source, the carbon dioxide gas source, and the oxygen gas source; and, in the direction from the raw gas source to the main pipe 111, the first branch pipe 112 is sequentially provided with a first pressure gauge 1121, a first solenoid valve 1122, a first mass flow meter 1123 and a first check valve 1124.

[0050] In this way, the air pressure in the corresponding first branch pipe 112 can be measured by the first pressure gauge 1121, and the first solenoid valve 1122 can be used to control the opening and closing of the corresponding first branch pipe 112. The first mass flow meter 1123 can accurately measure the mass flow of the fluid passing through the first branch pipe 112 and monitor the safety of the fluid flow. The first one-way valve 1124 can effectively ensure the flow direction of the fluid and avoid the problem of fluid backflow.

[0051] In one embodiment of the present application, Figure 2 and Figure 4 As shown, the raw material supply module 1 of the present application may also include a second gas fuel supply module 13, the second gas fuel supply module 13 includes a gas cylinder 131 and a second branch pipe 132, the gas outlet end of the gas cylinder 131 is detachably connected to one end of the second branch pipe 132, and the other end of the second branch pipe 132 is connected to the main pipe 111 in a switchable manner; and, in the direction from the gas cylinder 131 to the main pipe 111, the second branch pipe 132 is sequentially provided with a first ball valve 1321, a second pressure gauge 1322, a second solenoid valve 1323, a second mass flow meter 1324 and a second check valve 1325.

[0052] In this way, through the gas cylinder 131 set up in this way, other types of raw gas or reaction gas can be supplied to the reformer test system 100 of the present application, and it is easy to replace the gas cylinder 131, so as to facilitate the adjustment of the type of raw gas or reaction gas supplied.

[0053] At the same time, in this embodiment, the first ball valve 1321 can be used to block the second branch pipe 132 to facilitate the replacement of the gas cylinder 131. The second pressure gauge 1322 can be used to measure the gas pressure in the second branch pipe 132. The second solenoid valve 1323 can be used to control the on-off of the second branch pipe 132. The second mass flow meter 1324 can accurately measure the mass flow of the fluid passing through the second branch pipe 132 and monitor the safety of the fluid flow. The second one-way valve 1325 can effectively ensure the flow direction of the gas and avoid the problem of gas backflow.

[0054] In one embodiment of the present application, Figure 2 and Figure 5 As shown, the liquid fuel supply module 12 of the present application may include a liquid storage tank 121 and a liquid infusion pipe 122, the liquid outlet of the liquid storage tank 121 is detachably connected to one end of the liquid infusion pipe 122, and the other end of the liquid infusion pipe 122 is connected to the reforming reaction module 3 in a switchable manner; and, in the direction from the liquid storage tank 121 to the reforming reaction module 3, a constant flow pump 1221, a first flow meter 1222, a filter 1223, a third one-way valve 1224, an emptying three-way valve 1225 and a vaporization chamber 1226 are sequentially arranged on the liquid infusion pipe 122.

[0055] In this way, the liquid fuel supply module 12 configured in this way can supply the corresponding liquid raw material to the reformer test system 100 of the present application, and since the liquid outlet of the liquid storage tank 121 can be detachably assembled on the liquid infusion pipe 122, it is convenient for the tester to adjust or replace the type of liquid fuel supply.

[0056] At the same time, in this embodiment, the constant flow pump 1221 is used to pump liquid fuel into the reformer test system 100 of the present application. The first flow meter 1222 is used to measure the fluid flow through the infusion pipe 122. The filter 1223 is used to filter the fluid to ensure the safety and reliability of the reforming reaction. The third one-way valve 1224 can effectively ensure the flow direction of the liquid fuel and avoid the problem of liquid fuel backflow. The emptying three-way valve 1225 is used to empty the fluid in the infusion pipe 122. The vaporization chamber 1226 is used to vaporize the liquid fuel to facilitate the subsequent reforming reaction.

[0057] In one embodiment of the present application, Figure 2 and Figure 6 As shown, the water vapor supply module 2 of the present application may include a deionized water tank 21 and a water pipe 22, and the deionized water tank 21 is connected to the reforming reaction module 3 through the water pipe 22 in an on-off manner; and in the direction from the deionized water tank 21 to the reforming reaction module 3, the water pipe 22 is sequentially provided with a drain valve 221, a second ball valve 222, a third mass flow meter 223, a fourth one-way valve 224, a steam generator 225, a third solenoid valve 226 and a fifth one-way valve 227.

[0058] In this embodiment, the deionized water storage tank 21 is used to supply deionized water to the reformer test system 100 of the present application. The drain valve 221 is used to drain the deionized water in the water pipe 22. The second ball valve 222 is used to control the on-off of the water pipe 22. The third mass flow meter 223 is used to accurately measure the mass flow of deionized water passing through the water pipe 22 and to monitor the safety of the flow of deionized water. The fourth one-way valve 224 is used to control the flow direction of deionized water to prevent it from flowing back. The steam generator 225 is used to convert deionized water into steam and supply it to the reformer test system 100 of the present application. The third solenoid valve 226 is used to control the supply of steam. The fifth one-way valve 227 is used to control the flow direction of steam to prevent it from flowing back.

[0059] In one embodiment of the present application, Figure 2 and Figure 7 As shown, the reformer test system 100 may further include a SOFC tail gas access pipe 6 , one end of the SOFC tail gas access pipe 6 is used to communicate with the SOFC anode tail gas, and the other end of the SOFC tail gas access pipe 6 is used to communicate with the reforming reaction module 3 . The reforming reaction module 3 of the present application may include a reforming reactor 31, an electric furnace 32 mounted outside the reforming reactor 31, a first pipeline 33, a first electrically controlled three-way valve 34, a second pipeline 35, a third pipeline 36 and a second electrically controlled three-way valve 37. The inlet of the first electrically controlled three-way valve 34 is selectively connected to the raw material supply module 1, the water vapor supply module 2 and the SOFC tail gas access pipeline 6 through the first pipeline 33, the first outlet of the first electrically controlled three-way valve 34 is connected to the inlet of the reforming reactor 31, the second outlet of the first electrically controlled three-way valve 34 is connected to the first inlet of the second electrically controlled three-way valve 37 through the second pipeline 35, and the two ends of the third pipeline 36 are connected to the outlet of the reforming reactor 31 and the second inlet of the second electrically controlled three-way valve 37 respectively; the outlet of the second electrically controlled three-way valve 37 is connected to the gas analysis module 4.

[0060] In this embodiment, first, the electric furnace 32 is capable of providing different heating temperatures, so that the reforming reactor 31 of the present application can be adapted to the reforming temperature conditions of different fuels, so as to facilitate the testing of different reforming paths.

[0061] Second, by configuring the first pipeline 33, the first electrically controlled three-way valve, the second pipeline 35, the third pipeline 36 and the second electrically controlled three-way valve 37 in this way, the reforming reactor 31 of the present application can be switched between raw gas (raw gas corresponding to gas fuel and liquid fuel) testing and SOFC tail gas product testing to meet different testing requirements.

[0062] To facilitate understanding by relevant technical personnel, the working process / working principle of an exemplary reformer testing system 100 of the present application is described below.

[0063] First, prepare for the test, start the electric furnace 32 to heat the reforming reactor 31, and at the same time, turn on the purge gas (nitrogen) and discharge the tail gas (without igniting the burner). After reaching the reaction temperature, if the catalyst needs to be activated, use a hydrogen + nitrogen mixture to pass into the reformer and discharge the tail gas. After the test is completed, you can turn on the nitrogen for purging, and turn off the raw gas. After purging for a period of time, turn off the burner 51, continue purging and cool down the reforming reactor 31.

[0064] For example, when a methane steam reforming test is required, hydrogen and nitrogen can be turned off, and methane can be introduced, the steam generator 225 can be turned on, and methane and steam can be introduced into the reforming reactor 31 for reforming reaction. The tail gas generated is discharged after condensation and water vapor separation and then burned in the burner 51, and the gas components are measured at the same time. For another example, when a methane dry reforming test is required, the steam generator 225 and related valves can be turned off, and carbon dioxide can be introduced into the reforming reactor 31 for reforming reaction. The tail gas generated is discharged after condensation and water vapor separation and then burned in the burner 51, and the gas components are measured at the same time.

[0065] It should be noted that during the measurement of the adjustment or conversion of the reforming reaction type, the nitrogen gas can be opened to purge the pipeline between two different reforming types to avoid the impact between different experiments.

[0066] In addition, it should be noted that when direct testing of the raw gas is required, the first pipeline 33 can be connected to the corresponding raw material supply module 1 and / or water vapor supply module 2. At the same time, the first electrically controlled three-way valve 34 controls its first outlet to be closed and the second outlet to be connected. In this way, the raw gas will bypass the reforming reactor 31 and directly test the raw gas components.

[0067] When it is necessary to test the exhaust gas components after the raw gas reaction, the first pipeline 33 can be connected to the corresponding raw material supply module 1 and / or water vapor supply module 2. At the same time, the first electrically controlled three-way valve 34 controls its first outlet to be connected and the second outlet to be closed. In this way, the raw gas will enter the reforming reactor 31 for reaction, and then the reforming of the raw gas will be tested through the set gas analysis module 4.

[0068] Similarly, when it is necessary to test the SOFC tail gas product (SOFC tail gas is also used as a raw gas for a reforming reaction), the first pipeline 33 can be connected to the SOFC tail gas access pipeline 6. At the same time, the first electrically controlled three-way valve 34 controls its first outlet to be connected and the second outlet to be closed. In this way, the SOFC anode tail gas can enter the reforming reactor 31 for reaction, and then the tail gas components after the SOFC tail gas reforming can be tested through the set gas analysis module 4.

[0069] In one embodiment of the present application, Figure 2 and Figure 7 As shown, in the direction from the raw material supply module 1 to the first electrically controlled three-way valve 34, a mixing chamber 331, a pressure sensor 332 and a safety valve 333 are sequentially arranged on the first pipeline 33; a first temperature sensor 311 is arranged at the inlet of the reforming reactor 31, and at the same time, a second temperature sensor 312 is arranged at the outlet of the reforming reactor 31. The reforming reaction module 3 also includes a differential pressure sensor 38, which is used to obtain the pressure difference between the inlet and outlet of the reforming reactor 31.

[0070] In this embodiment, the mixing chamber 331 is used to mix the raw gas. The pressure sensor 332 is used to monitor the gas pressure in the first pipeline 33. The safety valve 333 is used for emergency pressure relief. The first temperature sensor 311 and the second temperature sensor 312 are used to obtain the temperature data of the inlet and outlet of the reforming reactor 31.

[0071] It should be noted that the differential pressure sensor 38 is used to obtain the pressure difference between the inlet and outlet of the reforming reactor 31. If the pressure difference is too large, it indicates that there may be a carbon deposition problem, or a gas path blockage problem caused by catalyst sintering. In this way, a first threshold value and a second threshold value (the first threshold value is less than the second threshold value) can be set. When the pressure difference is greater than the first threshold value, a warning signal is output to the outside to remind that there is a carbon deposition problem or a blockage problem. When the pressure difference is greater than the second threshold value, while outputting an alarm signal, all valves can be directly closed to ensure the safety of the reformer test system 100 of the present application.

[0072] It is understandable that the specific data of the first threshold and the second threshold can be adjusted according to actual conditions, and this application does not make any specific limitation on this.

[0073] In one embodiment of the present application, Figure 8 As shown, the gas analysis module 4 of the present application may include a third electrically controlled three-way valve 41, a fourth pipeline 42, a gas analyzer 43, a fifth pipeline 44, a fourth electrically controlled three-way valve 45, an FID total hydrocarbon analyzer 46 and a sixth pipeline 47. The inlet of the third electrically controlled three-way valve 41 is connected to the outlet of the reforming reactor 31, the first outlet of the third electrically controlled three-way valve 41 is connected to the gas analyzer 43 through the fourth pipeline 42, the second outlet of the third electrically controlled three-way valve 41 is connected to the inlet of the fourth electrically controlled three-way valve 45, the first outlet of the fourth electrically controlled three-way valve 45 is connected to the FID total hydrocarbon analyzer 46, the second outlet of the fourth electrically controlled three-way valve 45 is connected to the sixth pipeline 47, the sixth pipeline 47 is used to discharge exhaust gas, one end of the fifth pipeline 44 is connected to the fourth pipeline 42, and the other end of the fifth pipeline 44 is connected to the sixth pipeline 47.

[0074] The gas analyzer 43 thus arranged can measure the permanent gas components, reaction conversion rate and product selectivity of the relevant gas. The FID total hydrocarbon analyzer thus arranged can measure the conversion rate of hydrocarbons of complex composition. Thus, the composition and content of the gas reformed by the reformer can be accurately and quickly tested by measuring the above data.

[0075] In one embodiment of the present application, Figure 8 As shown, in the direction from the third electrically controlled three-way valve 41 to the gas analyzer 43 , a condenser 421 , a gas-water separator 422 and a second flow meter 423 are sequentially arranged on the fourth pipeline 42 , and the fifth pipeline 44 is connected to the downstream of the second flow meter 423 .

[0076] In this embodiment, the condenser 421 provided can cool the tail gas so that part of the tail gas is liquefied for easy separation; the gas-water separator 422 provided can separate the gas after the reforming reaction into gas and liquid so that the gas analyzer 43 can more accurately measure its gas components and contents. The second flowmeter 423 provided can measure the gas flow through the fourth pipeline 42. At the same time, since the fifth pipeline 44 is connected to the downstream of the second flowmeter 423, the gas measured by the gas analyzer 43 can be quickly and reliably discharged through the fifth pipeline 44.

[0077] In one embodiment of the present application, Figure 2 and Figure 8As shown, the reformer test system 100 of the present application may also include an exhaust gas treatment module 5, which includes a burner 51, a flame detector 52, a seventh pipeline 53, a natural gas source 54, an eighth pipeline 55 and an air compressor 56. The burner 51 is arranged on the sixth pipeline 47 and is located downstream of the fifth pipeline 44. The outlet of the FID total hydrocarbon analyzer 46 is connected to the sixth pipeline 47 and is located downstream of the burner 51. The natural gas source 54 is connected to the burner 51 through the seventh pipeline 53 in a switchable manner. The air compressor 56 is connected to the burner 51 through the eighth pipeline 55 in a switchable manner. The flame detector 52 is used to detect whether there is a flame in the burner 51; wherein, in the direction from the natural gas source 54 to the burner 51, a fourth mass flowmeter 531 and a fourth solenoid valve 532 are sequentially arranged on the seventh pipeline 53, and at the same time, in the direction from the air compressor 56 to the burner 51, a fifth mass flowmeter 551 and a fifth solenoid valve 552 are sequentially arranged on the eighth pipeline 55.

[0078] In this embodiment, the burner 51 provided can perform combustion treatment on the measured tail gas (because the hydrocarbon reforming process generally produces carbon monoxide, the tail gas treatment module 5 burns the carbon monoxide to generate carbon dioxide by burning natural gas ignition, reducing the emission of toxic gases, which plays an important role in experimental safety), avoiding environmental pollution and avoiding test safety risks. The flame controller provided is used to control the switch of the gas / liquid valve / pump of gases other than nitrogen and hydrogen. If there is no flame, the corresponding valve is automatically closed.

[0079] It should be noted that, when the reforming reaction is being carried out, the burner 51 should be turned on to burn the carbon monoxide produced by the reforming reaction, while the burner 51 does not need to be turned on during other gas purge processes.

[0080] At the same time, the natural gas source 54 is used to fill the burner 51 with natural gas, and the air compressor 56 is used to supply air to the burner 51, so that the exhaust gas in the burner 51 can be burned more thoroughly. The fourth mass flow meter 531 and the fifth mass flow meter 551 are used to accurately measure and monitor the fluid of the seventh pipeline 53 and the eighth pipeline 55, respectively. The fourth solenoid valve 532 and the fifth solenoid valve 552 are used to control the opening and closing of the seventh pipeline 53 and the eighth pipeline 55, respectively.

[0081] Furthermore, in this application, it is understood that

[0082] First, during the entire test process, if the pressure data collected by a pressure sensor 332 or a pressure gauge is greater than the working pressure (or set threshold) of the corresponding pipeline or equipment, an overpressure warning signal can be output to the outside, and / or all valves can be automatically closed directly to ensure the safety of the reformer test system 100 of the present application.

[0083] Second, see Figure 2 , Figures 6 to 8 For the upstream and downstream pipelines of the reformer, as well as some pipelines of the exhaust gas treatment module 5 and the gas analysis module 4, a pipeline heating coil 7 can be wrapped outside them to ensure that the fluid in the pipeline remains in a gaseous state, so as to ensure the smooth progress of the related reforming reaction process, gas analysis process and exhaust gas treatment process.

[0084] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
