Description

Technical Field

[0001] This invention relates to the field of gas penetration testing, and more particularly to a pipeline structure and testing method for gas penetration testing. Background Technology

[0002] When conducting gas penetration testing, the sample needs to be activated before the formal penetration test. Existing gas penetration testing pipeline structures typically include a four-way valve, which controls the entry of different gas sources into the pipeline by switching its open / closed state. Since the test gas and activation gas share the same pipeline, only one can usually be opened at a time, undoubtedly prolonging the waiting time and resulting in low testing efficiency.

[0003] Furthermore, when using existing piping structures for gas breakthrough testing, a portion of the test gas remains in the section of the piping directly connected to the detector. This test gas flows into the detector first during the breakthrough test, followed by the activated gas remaining in the piping, and finally, a continuous flow of test gas. The breakthrough test curve shows that the initial concentration of the adsorbate component is not zero, and exhibits a trend of first decreasing and then increasing. In gas breakthrough testing, the core purpose of integral calculation is to quantitatively calculate key parameters such as the saturated adsorption capacity and breakthrough adsorption capacity of the adsorbent through the integral area of ​​the concentration-time breakthrough curve. However, the curve distortion caused by the existing piping structure—"non-zero initial concentration, concentration decreasing and then increasing"—directly undermines the premise of integral calculation, leading to erroneous results. Summary of the Invention

[0004] This invention provides a pipeline structure and testing method for gas penetration testing, which solves the problem of low testing efficiency when using existing pipeline structures, and the problem that existing pipeline structures cause curve distortion of the adsorbate with "non-zero initial concentration and concentration decreasing first and then increasing", which directly undermines the premise of integral calculation and leads to incorrect results.

[0005] To achieve the above objectives, the present invention provides a pipeline structure for gas penetration testing, comprising: The first four-way valve includes ports A1, A2, A3, and A4. The second four-way valve includes ports B1, B2, B3, and B4. Port A4 is connected to port B4 via a pipeline. Test gas source, used to provide test gas, is connected to interface A1 through a pipeline; An activation gas source is used to provide activation gas. The activation gas source is connected to the A3 interface through a pipeline. The sample tube has its inlet end connected to the A2 interface via a pipe, and its exhaust end connected to the B2 interface via a pipe. The venting interface is connected to the B3 interface via a pipeline; The detector has its air inlet connected to the B1 interface via a pipe, and its exhaust end connected to the pipe connecting the B3 interface and the vent interface via a pipe.

[0006] In the initial state, interface A1 is connected to interface A4, interface A2 is connected to interface A3, interface B1 is connected to interface B2, and interface B3 is connected to interface B4. In the second state, the A1 interface is connected to the A4 interface, the A2 interface is connected to the A3 interface, the B1 interface is connected to the B4 interface, and the B2 interface is connected to the B3 interface. In the third state, the A1 interface is connected to the A2 interface, the A3 interface is connected to the A4 interface, the B1 interface is connected to the B2 interface, and the B3 interface is connected to the B4 interface.

[0007] As a preferred option, a first flow controller is installed on the pipeline connecting the test gas source and the A1 interface, and a second flow controller is installed on the pipeline connecting the activation gas source and the A3 interface.

[0008] As a preferred option, a pressure sensor is installed on the pipeline connecting the gas inlet of the sample tube and the A2 interface.

[0009] A gas penetration test method, using the aforementioned gas penetration test pipeline structure, includes the following operating steps: S1: Adjust the pipeline structure for the gas penetration test to the initial state, that is, connect the A1 interface to the A4 interface, the A2 interface to the A3 interface, the B1 interface to the B2 interface, and the B3 interface to the B4 interface. S2: Turn on the activation gas source and the test gas source. The test gas passes through the A1 interface, A4 interface, B4 interface, and B3 interface in sequence to the vent interface to achieve online gas mixing and pipeline pre-filling of multi-component test gas. The activation gas passes through the A3 interface and A2 interface in sequence to enter the sample tube to perform desorption and activation treatment on the sample in the tube, then enters the detector to detect the concentration of adsorbate components, and finally vents through the vent interface. S3: When the detector detects zero concentration signal of adsorbate components, it indicates that sample activation is complete. Switch the connection state of the second four-way valve, connecting interface B1 to interface B4 and interface B2 to interface B3. The test gas passes through interface A1, interface A4, interface B4, and interface B1 in sequence to the detector to detect the concentration of multi-component test gas, and finally is vented through the vent port. The activation gas passes through interface A3, interface A2, sample tube, interface B2, and interface B3 in sequence to the vent port for venting. S4: When the detector detects that the concentration signal of the multi-component test gas is stable, it indicates that the multi-component test gas has reached a state of equilibrium. Switch the pipeline structure of the gas penetration test to the initial state. S5: When the detector detects that the concentration signal of the adsorbate component is zero, switch the connection state of the first four-way valve, connecting the A1 interface with the A2 interface and the A3 interface with the A4 interface; the test gas enters the sample tube through the A1 interface and the sample in the tube in sequence, where it undergoes adsorption, and then enters the detector to detect the concentration of the adsorbate component, and finally exits through the venting interface; the activation gas passes through the A3 interface, A4 interface, B4 interface, and B3 interface in sequence to exit through the venting interface. S6: Start the computer data acquisition and analysis program linked to the detector, read the adsorbate component concentration-time response signal output by the detector in real time; process the response signal to obtain the gas penetration test results.

[0011] As a preferred option, a third flow controller is installed on the branch pipeline.

[0012] As a preferred embodiment, the following operation steps are also included: In step S2, the reference gas source (1) is turned on, and the reference gas provided by the reference gas source (1) is mixed online and pre-charged in the pipeline. The activation gas and the reference gas are mixed and then enter the detector (12); In step S3, the test gas and the reference gas are mixed and then enter the detector (12); In step S5, the test gas flowing out of the sample tube (10) and the reference gas transported by the branch pipeline are combined to form a mixed gas and enter the detector (12).

[0013] Specifically, it is a gas penetration test method using the aforementioned gas penetration test pipeline structure, comprising the following operating steps: I: Adjust the pipeline structure for the gas penetration test to the initial state, that is, connect the A1 interface to the A4 interface, the A2 interface to the A3 interface, the B1 interface to the B2 interface, and the B3 interface to the B4 interface. II: Turn on the activation gas source, test gas source, and reference gas source. The test gas passes through the A1, A4, B4, and B3 ports sequentially to the vent port for venting, so as to realize the online gas mixing and pipeline pre-charging of multi-component test gas and reference gas. The activation gas passes through the A3 and A2 ports sequentially to enter the sample tube to perform desorption and activation treatment on the sample inside the tube. The activation gas flowing out of the sample tube merges with the reference gas delivered by the branch pipeline to form a mixed gas and enters the detector. The detector detects the concentration of adsorbate components in the mixed gas in real time, and finally vents through the vent port. III: When the detector detects zero concentration signal of adsorbate components, it indicates that sample activation is complete. Switch the connection state of the second four-way valve, connecting interface B1 to interface B4 and interface B2 to interface B3. The test gas passes through interface A1, interface A4, interface B4, and interface B1 in sequence, merging with the reference gas delivered by the branch pipeline to form a mixed gas and entering the detector. The detector monitors the concentration of each component in the mixed gas in real time, and finally vents through the vent port. The activation gas passes through interface A3, interface A2, sample tube, interface B2, and interface B3 in sequence to the vent port for venting. IV: When the detector detects that the concentration signals of each component of the mixed gas are stable, it indicates that the test gas and the reference gas have reached gas mixing balance, and the pipeline structure for gas penetration testing is switched to the initial state. V: When the detector detects that the concentration signal of the adsorbate component is zero, the connection state of the first four-way valve is switched, connecting the A1 interface with the A2 interface and the A3 interface with the A4 interface; the test gas enters the sample tube through the A1 interface and the sample in the tube and undergoes adsorption. The test gas flowing out of the sample tube merges with the reference gas delivered by the branch pipeline to form a mixed gas and enters the detector. The detector detects the concentration of the adsorbate component in the mixed gas in real time and finally vents it through the vent interface; the activation gas passes through the A3 interface, A4 interface, B4 interface, and B3 interface in sequence to the vent interface for venting. VI: Start the computer data acquisition and analysis program linked to the detector, read the adsorbate component concentration-time response signal output by the detector in real time; process the response signal to obtain the gas penetration test results.

[0014] As a preferred embodiment, the data processing includes baseline calibration and noise filtering.

[0015] As a preferred embodiment, the gas penetration test results include a penetration test curve plotted with time as the horizontal axis and the concentration of each component as the vertical axis.

[0016] The gas penetration testing pipeline structure and testing method provided by this invention have at least the following advantages compared to existing technologies: 1. Performing online gas mixing and pipeline pre-filling while desorbing and activating the sample can reduce the waiting time during the test and improve the test efficiency. 2. In the breakthrough test curve, the initial value of the adsorbate component concentration is zero, and it gradually rises until it reaches a stable state without curve distortion, which meets the premise of integral calculation. Therefore, when performing integral calculation, it can effectively avoid calculation errors. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0022] In this invention, unless explicitly specified, the terms "connected" and "fixed" should be interpreted broadly. For example, "fixed" can mean a fixed connection or a detachable connection; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium. Furthermore, if the embodiments of this invention involve terms such as "first" or "second," these are used only for ease of description and do not imply their relative importance or the number of technical features. Those skilled in the art should understand the specific meaning of these terms in this invention according to the specific circumstances.

[0023] Example 1: refer to Figures 1 to 3 The gas penetration test pipeline structure provided in this embodiment is as follows: Figure 1 As shown: including: The first four-way valve 7 includes ports A1, A2, A3, and A4. The second four-way valve 8 includes ports B1, B2, B3, and B4. Port A4 is connected to port B4 via a pipeline. Test gas source 2 is used to provide test gas. Test gas source 2 is connected to interface A1 through a pipeline. Activation gas source 3 is used to provide activation gas. Activation gas source 3 is connected to interface A3 through a pipeline. The sample tube 10 has its inlet end connected to the A2 interface via a pipe and its exhaust end connected to the B2 interface via a pipe. The venting port 11 is connected to the B3 port via a pipeline; The detector 12 has its air inlet end connected to the B1 interface via a pipe, and its exhaust end connected to the pipe connecting the B3 interface and the vent interface 11 via a pipe.

[0024] Among them, the first four-way valve 7 and the second four-way valve 8 are often four-way ball valves. The flow channels on the ball of the four-way ball valve are arranged in an X shape, with the four channel ports evenly distributed on the equatorial circumferential section of the ball and corresponding to the four connecting ports on the valve body. When the operating mechanism drives the ball to rotate 90° through the valve stem, two adjacent channels can be connected to each other, thereby changing the flow direction of the fluid. The sample tube 10 has an inlet end and an outlet end. The sample for penetration testing is placed inside the sample tube 10. Various gases enter the sample tube 10 from the inlet end and pass through the sample, and then exit from the outlet end. There are many types of detectors 12 that can be used, such as mass spectrometers, electrochemical detectors, infrared absorption detectors, etc., or integrated gas analyzers (with flow metering function). Those skilled in the art can choose according to the experimental purpose.

[0025] As a preferred embodiment, a first flow controller 5 is installed on the pipeline connecting the test gas source 2 and the A1 interface, and a second flow controller 6 is installed on the pipeline connecting the activation gas source 3 and the A3 interface. The flow controllers are used to accurately measure and stably control the gas flow rate, ensuring that the gas flow rate is constant and the proportions are accurate during the experiment.

[0026] As a preferred embodiment, a pressure sensor 9 is installed on the pipeline connecting the gas inlet of sample tube 10 and the A2 interface. The pressure sensor 9 at the front end of sample tube 10 is used to monitor and control the gas pressure at the gas inlet of sample tube 10, ensuring stable experimental conditions, accurate data, and system safety.

[0027] Example 2: The gas penetration test method provided by this invention uses the gas penetration test pipeline structure of Example 1 and includes the following operating steps: S1: Adjust the piping structure for the gas penetration test to its initial state, such as... Figure 1 As shown, this means that interfaces A1 and A4 are connected, interfaces A2 and A3 are connected, interfaces B1 and B2 are connected, and interfaces B3 and B4 are connected.

[0028] S2: Turn on the activation gas source 3 and the test gas source 2. The test gas sequentially passes through interfaces A1, A4, B4, and B3 to the vent interface 11 for venting, thus achieving online gas mixing and pipeline pre-filling for multi-component test gases. The activation gas sequentially passes through interfaces A3 and A2 into the sample tube 10 to desorb and activate the sample inside, then enters the detector 12 to detect the concentration of adsorbate components, and finally vents through the vent interface 11. Activating the sample is to clean the pores, expose active sites, stabilize the surface state, and ensure accurate test data. It should be noted that the activation gas source 3 and the test gas source 2 can be turned on simultaneously. Online gas mixing and pipeline pre-filling can be performed while the sample desorption and activation process is underway, reducing waiting time and improving testing efficiency.

[0029] S3: When detector 12 detects zero adsorbate concentration signal, it indicates that sample activation is complete. Switch the connection state of the second four-way valve 8, such as... Figure 2 As shown, connect interface B1 to interface B4, and connect interface B2 to interface B3. The test gas passes through interface A1, interface A4, interface B4, and interface B1 in sequence to the detector 12 to detect the concentration of the multi-component test gas, and finally passes through the vent interface 11 to vent. The activation gas passes through interface A3, interface A2, sample tube 10, interface B2, and interface B3 in sequence to the vent interface 11 to vent.

[0030] S4: When detector 12 detects a stable concentration signal of the multi-component test gas, it indicates that the multi-component test gas has reached equilibrium. The gas penetration test pipeline structure is then switched to the initial state. Figure 1 As shown.

[0031] S5: When the detector 12 detects that the adsorbate component concentration signal is zero, switch the connection state of the first four-way valve 7, such as... Figure 3 As shown, the A1 and A2 interfaces are connected, and the A3 and A4 interfaces are connected. The test gas sequentially passes through the A1 and A2 interfaces into the sample tube 10, where it undergoes adsorption with the sample. It then enters the detector 12 to detect the concentration of the adsorbate component and is finally vented through the vent port 11. The activation gas sequentially passes through the A3, A4, B4, and B3 interfaces to the vent port 11 for venting. In the breakthrough test curve, the initial value of the adsorbate component concentration is zero, and it gradually rises until it reaches a stable state without curve distortion, which satisfies the premise of integral calculation. Therefore, when performing integral calculation, errors in the calculation results can be effectively avoided.

[0032] S6: Start the computer data acquisition and analysis program linked with detector 12, read the concentration-time response signal of the adsorbate component output by the detector in real time; after baseline calibration and noise filtering of the signal, plot the breakthrough test curve with time as the abscissa and the concentration of each component as the ordinate.

[0033] Example 3: refer to Figures 4 to 6 The gas penetration test pipeline structure provided in this embodiment, based on Embodiment 1, has a branch pipeline connected to the pipeline connecting the B1 interface and the detector 12. A reference gas source 1 is installed at the end of the branch pipeline to provide reference gas. The core advantage of adding a reference gas source 1 to the penetration curve test pipeline is improved accuracy, stability, and repeatability of the test data, especially in solving the baseline interference problem that is difficult to avoid with a single gas path system.

[0034] As a preferred option, a third flow controller 4 is installed on the branch pipeline. Its function is to accurately control the flow stability of the reference gas, ensuring the effectiveness of baseline calibration and data accuracy.

[0035] Example 4: The gas penetration test method provided in this embodiment uses the gas penetration test pipeline structure of Embodiment 3, and includes the following operating steps: I: Adjust the piping structure for the gas penetration test to its initial state, such as... Figure 4 As shown, this means that interfaces A1 and A4 are connected, interfaces A2 and A3 are connected, interfaces B1 and B2 are connected, and interfaces B3 and B4 are connected.

[0036] II: Open activation gas source 3, test gas source 2, and reference gas source 1. The test gas sequentially passes through interfaces A1, A4, B4, and B3 to vent through venting interface 11, enabling online gas mixing and pipeline pre-charging of multi-component test and reference gases. Activation gas sequentially passes through interfaces A3 and A2 into sample tube 10 to desorb and activate the sample. The activation gas exiting sample tube 10 merges with the reference gas delivered through the branch pipeline to form a mixed gas, which enters detector 12. Detector 12 monitors the concentration of adsorbate components in the mixed gas in real time, and finally vents through venting interface 11. Activation of the sample is performed to clean pores, expose active sites, stabilize the surface state, and ensure accurate test data. It should be noted that activation gas source 3, test gas source 2, and reference gas source 1 can be opened simultaneously. Online gas mixing and pipeline pre-charging can be performed simultaneously with sample desorption and activation, reducing waiting time and improving testing efficiency.

[0037] III: When detector 12 detects zero adsorbate concentration signal, it indicates that sample activation is complete. Then, switch the connection state of the second four-way valve 8, such as... Figure 5 As shown, connect interface B1 to interface B4, and connect interface B2 to interface B3. The test gas passes through interface A1, interface A4, interface B4, and interface B1 in sequence, and merges with the reference gas delivered by the branch pipeline to form a mixed gas and enters detector 12. Detector 12 detects the concentration of each component of the mixed gas in real time, and finally vents through vent interface 11. The activation gas passes through interface A3, interface A2, sample tube 10, interface B2, and interface B3 in sequence to vent through vent interface 11.

[0038] IV: When detector 12 detects stable concentration signals of each component in the mixed gas, indicating that the test gas and reference gas have reached gas mixing equilibrium, the pipeline structure for the gas penetration test is switched to the initial state, such as... Figure 4 As shown.

[0039] V: When detector 12 detects that the adsorbate concentration signal is zero, the connection state of the first four-way valve 7 is switched, such as... Figure 6 As shown, interfaces A1 and A2 are connected, and interfaces A3 and A4 are connected. The test gas sequentially enters sample tube 10 through interfaces A1 and A2, where it adsorbs onto the sample. The test gas exiting sample tube 10 merges with the reference gas supplied by the branch pipeline to form a mixed gas, which then enters detector 12. Detector 12 monitors the concentration of the adsorbate component in the mixed gas in real time, and the gas is finally vented through vent port 11. The activation gas sequentially passes through interfaces A3, A4, B4, and B3 before being vented through vent port 11. In the breakthrough test curve, the initial value of the adsorbate component concentration is zero, and it gradually increases until it reaches a stable state without curve distortion, satisfying the prerequisite for integral calculation. This effectively avoids calculation errors when performing integral calculations.

[0040] VI: Start the computer data acquisition and analysis program linked with detector 12, read the adsorbate component concentration-time response signal output by the detector in real time; after baseline calibration and noise filtering of the signal, plot the breakthrough test curve with time as the x-axis and the concentration of each component as the y-axis.
