Description

Technical Field

[0001] This application relates to the field of gas transfer technology, and in particular to a gas quantitative transfer system and method. Background Technology

[0002] In the testing of gases, the process of transferring gases is usually involved, such as transferring a certain amount of target gas to the testing equipment for testing, or transferring a certain amount of target gas to the reaction vessel for experimentation.

[0003] In related technologies, there are two methods for collecting target gases: sampling bag sampling and vacuum bottle sampling. In the sampling bag sampling process, a vacuum box and a sampling bag placed inside the vacuum box must be prepared first. Then, the vacuum box is evacuated and the target gas is introduced into the sampling bag. The above process is very cumbersome. At the same time, the sampling bag has poor sealing performance and can usually only be stored for 8 hours. In contrast, the vacuum bottle has better sealing performance and can be stored for 15-20 days. The vacuum bottle is also more convenient to operate.

[0004] There are two methods for pre-analyzing the target gas in the vacuum bottle. The first method involves pre-pressurizing the vacuum bottle by introducing nitrogen gas, then filling the metering loop by purging the gas from its outlet. However, in practice, if the target gas concentration in the vacuum bottle is already low, introducing nitrogen will further reduce the concentration, limiting the detection of the target gas. The second method involves directly drawing the target gas from the vacuum bottle into the metering loop using a vacuum pump. This method results in a negative pressure environment inside the metering loop, preventing the target gas from completely filling it. Summary of the Invention

[0005] This application aims to solve at least one of the technical problems existing in the prior art. To this end, this application proposes a gas quantitative transfer system and method.

[0006] In a first aspect, this application provides a gas quantitative transfer system, comprising:

[0007] First gas storage equipment;

[0008] A metering ring assembly, wherein the first air inlet of the metering ring assembly is connected to the first gas storage device;

[0009] A switching valve is provided, wherein the first outlet of the metering ring assembly is connected to the switching valve via a conduit, and the switching valve is used to connect to a pumping device or ambient gas.

[0010] A controller is electrically connected to the first gas storage device, the metering loop assembly, the switching valve, and the extraction device. The controller is configured to sequentially control the switching valve to connect with the ambient gas after the target gas from the first gas storage device enters the conduit when the extraction device has been running for a first target duration. The valve of the first gas storage device is then closed, and after the gas pressure in the metering loop assembly is balanced, the target gas is positioned within the conduit. The first inlet and the first outlet are then disconnected. According to the gas metering transfer system provided in this application, by extracting the target gas from the metering loop assembly into the conduit and restoring the gas pressure within the metering loop assembly to atmospheric pressure, and ensuring the target gas is positioned within the conduit, the metering loop assembly can be quantitatively filled with the target gas. This filling process is convenient and quick, and the target gas detection effect is good.

[0011] According to one embodiment of this application, the quantitative loop assembly includes:

[0012] The quantitative loop assembly includes: a quantitative loop and a multi-port injection valve, wherein the multi-port injection valve includes a first air inlet, a first air outlet, a second air outlet, and a second air inlet;

[0013] One end of the quantitative loop is connected to the first air inlet and the second air outlet, and the other end of the quantitative loop is connected to the first air outlet and the second air inlet. The controller is electrically connected to the multi-port injection valve and is used to control the first air inlet and the first air outlet to be connected to both ends of the quantitative loop, or to control the second air outlet and the second air inlet to be connected to both ends of the quantitative loop.

[0014] By adopting the above technical solution, the second outlet of the multi-port injection valve can be connected to other equipment. After the quantitative loop is filled, the first outlet and the second outlet are connected by controlling the opening of the connection, thereby quantitatively exporting the target gas to other equipment.

[0015] According to one embodiment of this application, when the gas pressure in the metering ring assembly is balanced and the target gas is in the conduit, the second outlet and the second inlet are controlled to be connected to both ends of the metering ring, and the second inlet is used to connect to the ambient gas, and the second outlet is used to connect to the gas detection device.

[0016] By adopting the above technical solution, it is possible to determine whether the tracer is mixed into the quantitative loop. If the tracer is mixed in, the duration of the first target is extended until the tracer is no longer mixed into the quantitative loop.

[0017] According to one embodiment of this application, a pressure sensor is provided between the first gas storage device and the first air inlet, or between the first air inlet and the first air outlet, or inside the conduit, and the pressure sensor is used to detect the gas pressure inside the metering ring assembly.

[0018] According to one embodiment of this application, the conduit includes a first airway, a second airway, and a third airway that are sequentially connected;

[0019] The end of the first air guide channel away from the second air guide channel is connected to the first air outlet, and the end of the third air guide channel away from the second air guide channel is connected to the switching valve. The radii of the first air guide channel and the third air guide channel are both not less than the radius of the second air guide channel.

[0020] By adopting the above technical solution, it is possible to avoid excessive negative pressure in the metering ring assembly caused by excessive suction force of the gas extraction equipment, which would lead to convection between the ambient gas and the target gas in the metering ring assembly.

[0021] According to one embodiment of this application, the controller includes:

[0022] The first acquisition unit is used to acquire the value of the time required to reach the first target;

[0023] The first control unit controls the switching valve to connect with the ambient gas based on the value of the first target duration;

[0024] The second acquisition unit is used to acquire the value of the time it takes for the gas pressure balance in the metering loop assembly to reach the second target after the switching valve is connected to the ambient gas.

[0025] The second control unit controls the first air inlet and the first air outlet to disconnect based on the value of the second target duration.

[0026] Secondly, this application provides a method for quantitative gas transfer, comprising:

[0027] The switching valve is connected to the pumping device, and when the pumping device runs for a first target duration, the target gas from the first gas storage device enters the conduit.

[0028] The switching valve is connected to the ambient gas in sequence control, and the valve port of the first gas storage device is closed;

[0029] When the gas pressure is balanced within the metering ring assembly and the target gas is in the duct, the first inlet and the first outlet are controlled to disconnect.

[0030] According to one embodiment of this application, when the gas pressure within the metering loop assembly is balanced and the target gas is located in the conduit, the method involves controlling the first inlet and the first outlet to disconnect.

[0031] The time it takes for the air pressure inside the metering loop assembly to reach equilibrium;

[0032] When the target gas is in the duct, the first inlet and the first outlet are controlled to disconnect based on the time it takes for the gas pressure in the metering loop assembly to reach equilibrium.

[0033] According to one embodiment of this application, before the gas extraction device reaches a first target duration and the target gas from the first gas storage device enters the conduit, the following steps are further included:

[0034] The first gas storage device is evacuated, and upon arrival at the sampling location, the first gas storage device is opened to obtain the target gas.

[0035] According to one embodiment of this application, when the target gas is in the conduit, after controlling the first inlet and the first outlet to disconnect based on the value of the time it takes for the gas pressure in the metering loop assembly to reach equilibrium, the method further includes:

[0036] Control the switching valve to connect to the second gas storage device;

[0037] When the target gas is in the duct, based on the value of the time it takes for the gas pressure in the metering loop assembly to reach equilibrium, the second outlet and the second inlet are controlled to be connected to both ends of the metering loop;

[0038] Extruded gas is introduced into the second air inlet, and the second air outlet of the metering ring assembly is connected to the gas detection device.

[0039] Thirdly, this application provides an electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the gas quantitative transfer method as described in the second aspect above.

[0040] Fourthly, this application provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the gas quantitative transfer method as described in the second aspect above.

[0041] Fifthly, this application provides a chip including a processor and a communication interface, the communication interface being coupled to the processor, the processor being used to run programs or instructions to implement the gas quantitative transfer method as described in the second aspect.

[0042] In a sixth aspect, this application provides a computer program product, including a computer program that, when executed by a processor, implements the gas quantitative transfer method as described in the second aspect above.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] 1. By extracting the target gas from the metering loop assembly into the conduit and restoring the gas pressure inside the metering loop assembly to normal pressure, and ensuring that the target gas is inside the conduit, it can be ensured that the metering loop assembly is completely filled with the target gas. The above filling process is convenient and quick, and the target gas detection effect is good.

[0045] 2. By ensuring that the radii of the first and third air guide channels are not less than the radius of the second air guide channel, excessive suction force of the pumping equipment can be avoided, which would lead to excessive negative pressure in the metering ring assembly and cause convection between the ambient gas and the target gas in the metering ring assembly.

[0062] The gas quantitative transfer system and method provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0063] like Figures 1-8 As shown, the gas quantitative transfer system includes: a first gas storage device 100, a quantitative loop assembly 200, a switching valve 300, and a controller.

[0064] like Figure 1 As shown, the first gas storage device 100 serves as a storage device for the target gas to be detected. The target gas can be stored at normal pressure inside the first gas storage device 100. The first gas storage device 100 can be a vacuum bottle or a sampling container.

[0065] like Figure 1 As shown, the metering ring assembly 200 serves as a metering transfer device for the target gas to be detected. The metering ring assembly 200 can have at least one of the following structural forms:

[0066] Firstly, the metering ring assembly 200 can be a metering ring 210, whose first air inlet 221 and first air outlet 222 can be connected to the two valve ports of the valve seat.

[0067] In this embodiment, after the metering ring 210 is filled, other valve ports of the valve seat can be connected to other devices. By controlling the opening and closing of the other valve ports connected to the other devices, the target gas can be quantitatively discharged.

[0068] Secondly, the metering ring assembly 200 can be a metering ring 210, and the first air inlet 221 and the first air outlet 222 of the metering ring 210 can be connected to control valves (not shown).

[0069] In this embodiment, once the metering ring 210 is filled, it is easy to quantitatively transfer the metering ring 210.

[0070] In addition, in the two possible structural forms mentioned above, the metering ring assembly 200 can also consist of multiple metering rings 210 connected in sequence, which can increase the volume of gas contained in the metering ring 210.

[0071] like Figure 1 As shown, the first air inlet 221 of the metering ring assembly 200 is connected to the first gas storage device 100, and the first air outlet 222 of the metering ring assembly 200 is connected to the switching valve 300 through the conduit 310. The switching valve 300 is used to connect to the pumping device 400 or the ambient gas. The switching valve 300 can be an electrically controlled three-way switching valve 300, and the pumping device 400 can be a pump.

[0072] The controller is electrically connected to the first gas storage device 100, the metering ring assembly 200, the switching valve 300, and the pumping device 400.

[0073] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the controller's control logic is set so that when the operation time of the pumping device 400 reaches the first target duration, after the target gas of the first gas storage device 100 enters the conduit 310, the switching valve 300 is sequentially controlled to connect with the ambient gas, the valve port of the first gas storage device 100 is closed, and after the gas pressure in the metering ring assembly 200 is balanced, the target gas is in the conduit 310, and the first air inlet 221 and the first air outlet 222 are disconnected.

[0074] In this embodiment, after the pumping device 400 has been running for a first target duration, the target gas can be drawn out of the metering ring assembly 200 and into the conduit 310. At this time, the gas pressure in the pumping device 400 and the metering ring assembly 200 is in a negative pressure state. By closing the valve of the first gas storage device 100, the communication between the first gas storage device 100 and the internal space of the metering ring assembly 200 is cut off. As a result, after the gas pressure in the metering ring assembly 200 is restored to normal pressure, the amplitude of the ambient gas flowing back along the conduit 310 towards the metering ring assembly 200 is reduced, ensuring that the target gas can be in the conduit 310. After the first air inlet 221 and the first air outlet 222 are disconnected, the metering filling of the target gas is completed.

[0075] According to the gas quantitative transfer system provided in the embodiments of this application, by extracting the target gas from the quantitative ring assembly 200 into the conduit 310 and restoring the gas pressure in the quantitative ring assembly 200 to normal pressure, and with the target gas inside the conduit 310, it can be ensured that the quantitative ring assembly 200 is completely filled with the target gas. The above filling process is convenient and quick, and the target gas detection effect is good.

[0076] It should be noted that the first target duration can be the test duration during which the target gas is extracted from the metering ring assembly 200 and enters the conduit 310, and the target gas remains in the conduit 310 after the gas pressure in the metering ring assembly 200 is balanced. This test duration can be measured experimentally.

[0077] Meanwhile, the first target duration can also be the time it takes for the target gas to be extracted from the metering ring assembly 200 and enter the conduit 310, and for the gas pressure in the pumping device 400 and the metering ring assembly 200 to reach the target pressure. This target pressure is preset after the gas pressure in the metering ring assembly 200 is balanced and the target gas is in the conduit 310. The pressure in the pumping device 400 and the metering ring assembly 200 can be measured by a pressure sensor.

[0078] For example, a pressure sensor can be installed between the first gas storage device 100 and the first air inlet 221, or between the first air inlet 221 and the first air outlet 222, or inside the conduit 310. The pressure sensor is electrically connected to the controller and is used to detect the gas pressure (not shown) inside the metering loop assembly 200.

[0079] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the quantitative loop assembly 200 includes a quantitative loop 210 and a multi-port injection valve 220.

[0080] The multi-port injection valve 220 includes a first air inlet 221, a first air outlet 222, a second air outlet 223, and a second air inlet 224. One end of the metering loop 210 is connected to the first air inlet 221 and the second air outlet 223, and the other end of the metering loop 210 is connected to the first air outlet 222 and the second air inlet 224. The controller is electrically connected to the multi-port injection valve 220 and is used to control the first air inlet 221 and the first air outlet 222 of the multi-port injection valve 220 to connect with the two ends of the metering loop 210, or to control the second air outlet 223 and the second air inlet 224 to connect with the two ends of the metering loop 210.

[0081] In this embodiment, the second outlet 223 of the multi-port injection valve 220 can be connected to other devices. After the metering loop 210 is filled, the first inlet 221 and the first outlet 222 are connected to both ends of the metering loop 210, and the second outlet 223 and the second inlet 224 are connected to both ends of the metering loop 210, thereby quantitatively exporting the target gas to other devices.

[0082] In practice, the multi-port injection valve 220 can be a six-port injection valve or an eight-port injection valve.

[0083] In some examples, such as Figure 3 and Figure 4 As shown, when the gas pressure in the metering ring assembly 200 is balanced and the target gas is in the conduit 310, the second outlet 223 and the second inlet 224 are connected to both ends of the metering ring 210, and the second inlet 224 is used to connect with the extruded gas, and the second outlet 223 is used to connect with the gas detection device 600.

[0084] In this example, the second gas storage device 500 is used to store ambient gas, and the second gas storage device 500 is in a normal pressure state during use. For example, the second gas storage device 500 can be a sampling bag, and the ambient gas is a high-concentration tracer. During the process of the gas pressure in the metering loop 210 returning to normal pressure, the tracer will flow back along the conduit 310 towards the metering loop 210 until it stabilizes. By connecting the second outlet 223 and the second inlet 224 to both ends of the metering loop 210, the extruded gas is introduced from the second inlet 224, and the target gas in the metering loop 210 is introduced into the gas detection device 600, thereby determining whether the tracer is mixed in the metering loop 210. If the tracer is mixed in, the first target duration is extended until the tracer is no longer mixed in the metering loop 210.

[0085] In practice, the extruded gas is not the same type of gas as the ambient gas and tracer. The extruded gas and the ambient gas can be nitrogen, hydrogen, etc. respectively; the gas detection equipment 600 can be a gas phase mass spectrometer (GCMS).

[0086] In some embodiments, such as Figure 3 and Figure 4 As shown, the first gas storage device 100 includes multiple gas storage tanks 110 and a multi-position injection valve 120. The multiple gas storage tanks 110 can be selectively and airtightly connected to the inlet valve of the multi-position injection valve 120, and the outlet valve of the multi-position injection valve 120 is airtightly connected to the quantitative ring assembly 200.

[0087] In actual operation, the outlet of the multi-position injection valve 120 can be airtightly connected to the quantitative loop assembly 200 through a pipeline, and the pipeline should be as short as possible to reduce the impact of ambient gas backflow along the conduit 310 on the convection of the target gas in the quantitative loop assembly 200.

[0088] In some embodiments, such as Figure 5 As shown, the conduit 310 includes a first airway 311, a second airway 312, and a third airway 313 connected in sequence.

[0089] The end of the first air guide 311 away from the second air guide 312 is connected to the first air outlet 222, and the end of the third air guide 313 away from the second air guide 312 is connected to the switching valve 300. The radii of the first air guide 311 and the third air guide 313 are not less than the radius of the second air guide 312.

[0090] In this embodiment, when the diameter of the first air outlet 222 is large compared to the diameter of the valve port of the switching valve 300, the first air guide channel 311 and the third air guide channel 313 can be designed to correspond to the diameters of the first air outlet 222 and the valve port of the switching valve 300, respectively, to facilitate connection. At the same time, it is also necessary to ensure that the radius of the second air guide channel 312 is as small as possible, that is, the radius of the second air guide channel 312 is smaller than the radius of the first air guide channel 311 and the third air guide channel 313, so as to avoid excessive suction force of the pumping device 400, resulting in excessive negative pressure in the metering ring assembly 200, and convection between the ambient gas and the target gas in the metering ring assembly 200.

[0091] For the same purpose, the length of the second airway 312 needs to be adjusted adaptively, that is, the length of the second airway 312 also needs to be as long as possible.

[0092] Of course, when the diameter of the first air outlet 222 is not large compared with the diameter of the valve port of the switching valve 300, the diameters of the first air guide 311 and the third air guide 313 can be adjusted accordingly, that is, the diameters of the first air guide 311, the second air guide 312 and the third air guide 313 can be equal.

[0093] In some embodiments, the controller includes: a first acquisition unit, a first control unit, a second acquisition unit, and a second control unit.

[0094] The first acquisition unit is used to acquire the value of the time required to reach the first target.

[0095] The first control unit controls the switching valve 300 to connect with the ambient gas based on the value of the first target duration.

[0096] The second acquisition unit is used to acquire the time it takes for the gas pressure in the metering loop assembly 200 to reach equilibrium after the switching valve 300 is connected to the ambient gas, and to set this time as the second target time.

[0097] The second control unit controls the first air inlet 221 and the first air outlet 222 to disconnect based on the value of the second target duration.

[0098] The gas quantitative transfer method provided in this application can be executed by an electronic device or a functional module or entity in an electronic device that can implement the gas quantitative transfer method. The electronic devices mentioned in this application include, but are not limited to, mobile phones, tablets, computers, cameras, and wearable devices. The following uses an electronic device as the execution subject to illustrate the gas quantitative transfer method.

[0099] like Figure 9 As shown, the gas quantitative transfer method includes steps 610, 620 and 630.

[0100] Step 610: Control the switching valve 300 to connect with the pumping device 400. When the pumping device 400 has been running for a first target duration, the target gas from the first gas storage device 100 is allowed to enter the conduit 310.

[0101] In this step, such as Figure 6 and Figure 9 As shown, after the pumping device 400 has been running for the first target duration, the target gas can be extracted from the metering ring assembly 200 and enter the conduit 310. At this time, the gas pressure in the pumping device 400 and the metering ring assembly 200 is in a negative pressure state.

[0102] In actual implementation, the first target duration can be the test duration during which the target gas is extracted from the metering ring assembly 200 and enters the conduit 310, and the target gas remains in the conduit 310 after the gas pressure in the metering ring assembly 200 is balanced.

[0103] The first target duration can also be the time it takes for the target gas to be extracted from the metering ring assembly 200 and enter the conduit 310, and for the pressure in the pumping device 400 and the metering ring assembly 200 to reach the target pressure. It is also necessary to ensure that the target gas is in the conduit 310 after the gas pressure in the metering ring assembly 200 is balanced. The target pressure can be preset, and the pressure in the pumping device 400 and the metering ring assembly 200 can be measured by a pressure sensor.

[0104] For example, a pressure sensor can be installed between the first gas storage device 100 and the first air inlet 221, or between the first air inlet 221 and the first air outlet 222, or inside the conduit 310. The pressure sensor is electrically connected to the controller and is used to detect the gas pressure inside the metering ring assembly 200.

[0105] Step 620: The sequential control switching valve 300 is connected to the ambient gas, and the valve port of the first gas storage device 100 is closed.

[0106] In this step, such as Figure 7 and Figure 9 As shown, by first connecting the switching valve 300 to the ambient gas and then closing the valve port of the first gas storage device 100, the purpose of cutting off the connection between the first gas storage device 100 and the internal space of the metering ring assembly 200 is to bring the gas pressure inside the metering ring assembly 200 back to normal pressure. The above process is used to reduce the amplitude of the ambient gas flowing back along the conduit 310 towards the metering ring assembly 200, ensuring that the target gas can be inside the conduit 310.

[0107] Step 630: When the gas pressure in the metering ring assembly 200 is balanced and the target gas is in the conduit 310, control the first air inlet 221 and the first air outlet 222 to disconnect.

[0108] In this step, such as Figure 8 and Figure 9 As shown, the gas pressure inside the metering ring assembly 200 is at normal pressure, and the target gas is inside the conduit 310. The first air inlet 221 and the first air outlet 222 are disconnected to complete the metering filling of the target gas.

[0109] According to the gas quantitative transfer method provided in the embodiments of this application, by extracting the target gas from the quantitative ring assembly 200 into the conduit 310 and restoring the gas pressure in the quantitative ring assembly 200 to normal pressure, and with the target gas inside the conduit 310, it can be ensured that the quantitative ring assembly 200 is quantitatively filled with the target gas. The above filling process is convenient and quick, and the target gas detection effect is good.

[0110] In some embodiments, before step 610, the method further includes: evacuating the first gas storage device 100, arriving at the sampling location, and opening the first gas storage device 100 to obtain the target gas.

[0111] In actual operation, the first gas storage device 100 can be a sampling tank. When the sampling location is reached, the vacuum sampling tank is opened, the target gas will enter the sampling tank, and the sampling tank can be restored to normal pressure.

[0112] In some embodiments, step 630 includes:

[0113] Step 631: Obtain the time it takes for the air pressure in the quantitative loop assembly 200 to reach equilibrium, and set this time as the second target time.

[0114] In this step, the time it takes for the air pressure inside the metering loop assembly 200 to reach equilibrium is obtained by a pressure sensor.

[0115] Step 632: When the target gas is in the conduit 310, based on the value of the second target duration, control the first air inlet 221 and the first air outlet 222 to disconnect.

[0116] In this step, the controller controls the first air inlet 221 and the first air outlet 222 to disconnect based on the value of the second target duration.

[0117] In some embodiments, after step 632, the method further includes:

[0118] Step 6321: Control the switching valve 300 to connect to the second gas storage device 500.

[0119] Step 6322: With the target gas in the conduit 310, based on the value of the time it takes for the gas pressure in the metering ring assembly 200 to reach equilibrium, control the second outlet 223 and the second inlet 224 to connect with both ends of the metering ring 210.

[0120] Step 6323: Introduce extruded gas into the second air inlet 224 and connect the second air outlet 223 of the metering ring assembly 200 to the gas detection device 600.

[0121] In this embodiment, the second gas storage device 500 is used to store ambient gas, and the second gas storage device 500 is in a normal pressure state during use. For example, the second gas storage device 500 can be a sampling bag, and the ambient gas is a high-concentration tracer. When the target gas is in the conduit 310, the quantitative ring 210 of the quantitative ring assembly 200 has completed the quantitative filling of the target gas. At this time, the second outlet 223 and the second inlet 224 are connected to the two ends of the quantitative ring 210, and the extruded gas is introduced into the second inlet 224. The target gas is introduced into the gas detection device 600 through the extruded gas, thereby determining whether the tracer is mixed in the quantitative ring 210. If the gas detection device 600 detects the tracer, the tracer is mixed in the quantitative ring 210. The first target duration is extended until the gas detection device 600 no longer detects the tracer.
