[0039] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] The following is a further detailed description of the implementation methods of the present application in conjunction with the accompanying drawings and examples. The detailed descriptions and drawings of the following examples are used to illustrate the principles of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0041] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0042] like Figure 1-6 As shown, Figure 1 In the figure, the inner sleeve structure is processed in perspective so that the first slide rail 221 inside the inner sleeve 22 can be observed. A denitration catalyst pilot test bench comprises a reactor 1, a transfer device 2, a sample loading device 3 and a moving device 4. The reactor 1 comprises a shell 11, and a smoke inlet pipe 12 and a smoke outlet pipe 13 arranged in the shell 11.

[0043] The moving device 4 is disposed between the reactor 1 and the transfer device 2 . The moving device 4 is used to move the transfer device 2 from the sample loading area 212 to the housing 11 . The sample loading device 3 is used to load the catalyst onto the transfer device 2 .

[0044] When the test bench is working, the air inlet and air outlet of the transfer device 2 are respectively sealed and connected to the smoke inlet pipe 12 and the smoke outlet pipe 13 to form a closed loop. The smoke inlet pipe 12 introduces smoke to the air inlet of the transfer device 2 to perform performance testing on the catalyst loaded on the transfer device 2.

[0045] In the present disclosure, the detection test bench has a high degree of automation integration. Compared with the traditional test bench detection, the test bench of the present disclosure can realize automatic loading of the catalyst into the shell 11 of the reactor 1 through the mobile device 4, which replaces a large amount of manual work and improves work efficiency.

[0046] In some embodiments, the transfer device 2 includes a transfer platform 21 , an inner sleeve 22 and a conveying platform 23 .

[0047] The transfer platform 21 has an unloading area 211 and a sample loading area 212 in the length direction. The inner sleeve 22 is arranged in the sample loading area 212 and connected to the moving device 4. The inner sleeve 22 has an air inlet end corresponding to the smoke inlet pipe 12 and an air outlet end corresponding to the smoke outlet pipe 13. The transfer platform 23 is slidably arranged in the unloading area 211. When the catalyst is transferred, the transfer platform 23 carries the catalyst and slides into the inner sleeve 22.

[0048] In the present disclosure, by dividing the transfer table into an unloading area and a loading area, and utilizing a slidable transfer table, the catalyst sample can be loaded and unloaded quickly and conveniently, reducing the time and labor intensity of manual handling. The design of the inner sleeve allows the catalyst to be directly transported from the transfer table to the test equipment, simplifying the operation process. Furthermore, due to the use of a mechanized transfer method, the risk of direct manual contact with high temperature or harmful gases is reduced, the position of the catalyst sample can be better controlled, and accidental drops or other safety risks can be reduced.

[0049] In some embodiments, the inner sleeve 22 is provided with a first slide rail 221 extending along its length direction, and the conveying platform 23 is provided with a first slide groove, wherein when transporting the catalyst, the conveying platform 23 cooperates with the first slide rail 221 through the first slide groove to slide into the inner sleeve 22.

[0050] In the present disclosure, the accurate alignment of the conveyor platform in the inner sleeve can be ensured by the precise cooperation of the first slide rail and the first slide groove, thereby ensuring that the catalyst sample can be accurately placed in the predetermined position. The design of the slide rail and the slide groove provides a stable guiding effect, reducing the shaking or deviation that may occur during the movement of the conveyor platform. The stable operation process can reduce the damage or uneven distribution of the catalyst caused by mechanical errors, thereby improving the success rate of the experiment. Furthermore, due to the guiding effect of the slide rail and the slide groove, the operator can more easily push or pull the conveyor platform into or out of the inner sleeve without the need for additional adjustment or calibration steps, making the process of loading and unloading the catalyst simpler and faster, reducing the difficulty of operation and improving work efficiency. In addition, the cooperation of the slide rail and the slide groove limits the moving direction of the conveyor platform, preventing accidental lateral movement or tilting, thereby reducing the risk of catalyst falling or leaking, and also helping to protect the operator from injuries caused by improper operation.

[0051] In some embodiments, the moving device 4 includes a driving motor 41 , a threaded shaft 42 and a fixing member 43 .

[0052] The driving motor 41 is disposed on the housing 11 , the threaded shaft 42 is drivingly connected to the driving motor 41 , the fixing member 43 is screwed to the threaded shaft 42 , and the fixing member 43 is fixedly connected to the inner sleeve 22 .

[0053] When the driving motor 41 is working, the threaded shaft 42 drives the fixing member 43 to move axially along the threaded shaft 42 to drive the inner sleeve 22 to move from the sample loading area 212 to the shell 11, or to drive the inner sleeve 22 to move from the shell 11 to the sample loading area 212.

[0054] In the present disclosure, the precise control of the position of the inner sleeve can be achieved by the cooperation of the drive motor and the threaded shaft. The threaded shaft provides a stable linear motion, so that the inner sleeve can be moved in a very fine manner, which helps to ensure the accurate positioning of the catalyst sample in the sample loading area and the shell, thereby improving the accuracy and repeatability of the experiment. The use of the drive motor realizes the automation of the movement of the inner sleeve, reduces the need for manual intervention, improves the operating efficiency, and the automated movement process can reduce human operation errors and ensure the consistency of each experiment.

[0055] Furthermore, the design of the threaded shaft and fixture provides a smooth and continuous movement path, avoiding abrupt or uneven movement, which helps maintain the integrity of the catalyst sample, and because the movement process is automated, the operator does not need to manually move the inner sleeve, reducing the risk of contact with high temperatures or hazardous gases.

[0056] In some embodiments, the moving device 4 further includes a second slide rail 44, which is disposed between the housing 11 and the transfer platform 21, and the inner sleeve 22 is provided with a second slide groove. When the inner sleeve 22 is moved from the sample loading area 212 to the housing 11, the inner sleeve 22 slides into the housing 11 through the cooperation between the second slide groove and the second slide rail 44.

[0057] In the present disclosure, the cooperation of the second slide rail and the second slide groove provides a precise guiding function for the inner sleeve, ensuring that it can accurately move along a predetermined path during the movement process, helping to reduce the position error caused by offset or tilt, and improving the accuracy of the positioning of the inner sleeve. The structure of the slide rail and the slide groove can effectively prevent the inner sleeve from shaking or deviating during the movement process, making the entire movement process more stable, and the stable movement reduces the impact on the catalyst sample, avoiding damage or uneven distribution of the sample due to unstable movement.

[0058] Furthermore, through the cooperation of the slide rail and the slide groove, the inner sleeve can slide smoothly from the sample loading area into the shell under the action of the drive motor, which simplifies the operation process, and the automated sliding mechanism reduces the need for manual intervention, improves operating efficiency, and reduces operating difficulty.

[0059] In some embodiments, the transfer device 2 further includes a pneumatic sealing structure 24, which is disposed on the outer periphery of the inner sleeve 22. When the catalyst is subjected to a performance test, the pneumatic sealing structure 24 extends a sealing strip along the inner sleeve 22, and the sealing strip contacts the circumference of the catalyst to form a sealed environment with the catalyst in the inner sleeve 22.

[0060] In the present disclosure, the pneumatic sealing structure can fit closely to the surface of the catalyst, effectively prevent the leakage of gas or liquid, and ensure the airtightness of the reaction environment during the experiment. By forming a good sealing environment, the influence of the external environment on the experimental results can be avoided, and the accuracy and reliability of the data can be improved. The pneumatic sealing structure can automatically adjust the extension length of the sealing strip according to the specific size of the catalyst, so as to adapt to catalyst samples of different sizes and shapes, so that the test bench can handle various types of catalysts, improving the versatility and scope of application of the equipment.

[0061] In some embodiments, a sealing gasket is provided at one end of the first slide rail 221 located at the air inlet end of the inner sleeve 22, wherein when the conveying platform 23 slides to the inner sleeve 22, the end of the conveying platform 23 close to the inner sleeve 22 is sealed and connected to the sealing gasket to seal the inner sleeve 22 together.

[0062] In the present disclosure, by providing a sealing gasket at the air inlet end of the inner sleeve, and when the conveyor enters the inner sleeve, it contacts the sealing gasket to form a seal, the sealing performance of the entire system can be further improved. The use of a double sealing mechanism (pneumatic sealing structure and sealing gasket) ensures that the environment inside the inner sleeve is completely isolated from the external environment to prevent gas or liquid leakage.

[0063] The automatic sealing connection between the transfer table and the sealing pad simplifies the sealing process and eliminates the need for additional manual sealing steps. The automated sealing connection improves operational efficiency, reduces human intervention, and reduces operational complexity.

[0064] In some embodiments, the pneumatic sealing structure 24 includes a top sealing structure 241 and two opposite side sealing structures 242. The top sealing structure 241 is disposed at the top of the inner sleeve 22 and is opposite to the first slide rail 221. The two opposite side sealing structures 242 are located between the top sealing structure 241 and the first slide rail 221 and are opposite to each other on the circumference of the inner sleeve 22.

[0065] In the present disclosure, by setting sealing structures at different positions such as the top and side of the inner sleeve, all-round sealing of the catalyst sample can be achieved. This setting can more effectively prevent gas or liquid leakage and ensure that the experimental environment is completely sealed.

[0066] Multiple sealing points (top seal, two side seals) work together. Even if a minor problem occurs in one sealing point, the other sealing points can continue to function, thus improving the reliability of the overall seal.

[0067] In some embodiments, the top sealing structure 241 and the side sealing structure 242 are alternately arranged along the length direction of the inner sleeve 22 .

[0068] In the present disclosure, the staggered sealing structure can provide a more uniform sealing pressure distribution, ensuring the sealing over the entire length of the inner sleeve. This design reduces the impact of failure of a single sealing point on the overall sealing effect and improves the overall sealing reliability of the system.

[0069] The staggered setting enables the sealing structure to better adapt to catalyst samples of different shapes and sizes. The design can more effectively fill the gaps around the catalyst, thereby forming a tighter sealing environment.

[0070] In some embodiments, the sample loading device 3 includes a base 31 , a robotic arm 32 and a robotic hand 33 , wherein the robotic arm 32 is disposed on the base 31 , and the robotic hand 33 is disposed on the robotic arm 32 , wherein the sample loading device 3 loads the catalyst onto the transfer device 2 through the robotic hand 33 .

[0071] In the present disclosure, the automated loading of catalyst samples can be achieved through the cooperation of the robotic arm and the manipulator, reducing the need for manual intervention. Automated operation improves experimental efficiency, reduces the possibility of human error, and can be run for a long time without human supervision.

[0072] The robot arm and manipulator can precisely control the position and posture of the catalyst sample, ensuring that each loading is highly consistent. High-precision operation helps improve the accuracy and repeatability of experimental results, which is very important for scientific research and industrial applications.

[0073] The present disclosure provides a specific example, including:

[0074] The pilot test bench for the denitration catalyst comprises: a smoke inlet pipeline 12, a smoke outlet pipeline 13, a reactor 1, a hydraulic device integrated box 5, an inner sleeve 22, a second slide rail 44, a threaded shaft 42, a drive motor 41, a transfer platform 21, a conveying platform 23, a robotic arm 32, a robotic arm 33, a base 31, a leak detection device 6 and a control device 7.

[0075] The working principle of the test bench disclosed in the present invention is as follows: after testing one project, when the temperature drops to about 100°C (to prevent the catalyst from cracking due to thermal expansion and contraction), the upper insulation cover 14 of the reactor 1 is opened by the touch button on the high-definition intelligent LED display screen 71 on the control device 7. The opening and closing of the insulation cover 14 is completed by the extension and retraction of the hydraulic rod arranged in the shell 11.

[0076] Furthermore, the hydraulic pressure in the hydraulic device integrated box 5 on both sides of the reactor 1 is automatically released synchronously, so that the inner sleeve 22 is loosened, the driving motor 41 and the threaded shaft 42 are activated, and the inner sleeve 22 is dragged out on the second slide rail 44 through the fixing member 43. The inner sleeve 22 stops running after reaching the first slide rail stopper 8 at one end of the second slide rail 44, and the inner sleeve 7 is placed in the sample loading area of ​​the transfer platform 21.

[0077] The internal pneumatic sealing structure of the inner sleeve 7 (including the top sealing structure, the first side sealing structure and the second side sealing structure) moves to separate from the catalyst, and the robot arm 32 drives the robot hand 33 to extend until the gripping portion 9 of the robot hand 33 stops. The robot hand 33 grasps the gripping portion 9, and the robot arm 32 contracts to pull the conveying platform 23 through the first slide rail 221 to the unloading area 211 of the transfer platform 21, and the conveying platform 23 stops after reaching the conveying platform limiter 10, and the test catalyst 50 sample is removed.

[0078] Replace the new catalyst: place the catalyst 50 of the next project on the conveying platform 23 located at the unloading area 211 of the transfer platform 21, and control the retractable robotic arm 32 to automatically extend through the touch button on the high-definition intelligent LED display screen 71 of the control device 7, so that the robotic arm 33 grasps the grasping part 9 to hold the catalyst conveying platform 23, and pushes it to the through-length limiter 20 of the first slide rail 221 through the first slide rail 221, wherein the through-length limiter 20 is set at one end of the first slide rail 221 located at the air inlet end of the inner sleeve 22.

[0079] The three ends of the through-length stopper 20 are connected to the inner sleeve 22. A sealing gasket is arranged inside the through-length stopper 20. The sealing gasket is a high-temperature sealing gasket and forms a bottom seal with the conveying platform 23. In the inner sleeve 22, the pneumatic sealing structure 24 (including the top sealing structure 241 and the side sealing structure 242) moves, and the overall sealing strip (including the top sealing strip 2411 extending from the top sealing structure 241, and the side sealing strip 2421 extending from the side sealing structure 242) extends to form a three-side seal with the catalyst. The sealing structure achieves the sealing purpose through pressure induction, and can achieve the installation and sealing of catalysts with different cross-sectional areas. Among them, the pneumatic sealing structure 24 is supplied with air through the first air supply pipe 40.

[0080] The driving motor 41 and the threaded rotating shaft 42 are in motion, and the inner sleeve 22 is dragged on the second slide rail 44 through the fixing member 43 to move into the shell 11 of the reactor 1, and stops running after reaching the second slide rail stopper 30 of the second slide rail 44 located in the shell 11. The smoke inlet pipe 12 and the smoke outlet pipe 13 are automatically pressed upward synchronously through the corresponding hydraulic device integrated box 5, and are sealed and connected with the air inlet end and the air outlet end of the inner sleeve 22 respectively, so as to form a seal with the inner sleeve 7. The smoke inlet of the smoke inlet pipe 12 and the smoke outlet of the smoke outlet pipe are provided with high temperature resistant sealing gaskets, and the inner sleeve 22 is sealed by the sealing gaskets.

[0081] Close the valves at both ends of the reactor 1, and the air supply pipe of the leak detection device 6 is activated to fill the inner sleeve 22 in the reactor 1 with 3KPa of air, and the leakage rate per second is less than 40Pa, which lasts for 30 seconds. If it is within the qualified air pressure range, it is in a qualified seal, and the valves at both ends of the reactor 1 will be automatically opened, and the upper outer cover 14 of the reactor 1 will be covered. Among them, the valves at both ends of the reactor 1 are correspondingly set on the smoke inlet pipe 12 and the smoke outlet pipe 13.

[0082] like Figure 2 In the state shown, the flue gas is heated to carry out catalyst detection. If the pressure is lower than the qualified pressure, an alarm is triggered. The qualified seal can be achieved by adjusting the pressure intensity or manually replacing the high-temperature resistant sealing gasket.

[0083] The control device 7 is composed of a power module, an electrical component, a CPU module, an analog module, a digital conversion module, a switch, and an industrial computer. The power supply of all equipment components can be controlled by the power module and the electrical component. The valve switch, hydraulic press action, transmission device action, gas supply, and mechanical arm operation can be controlled by the local touch screen or the remote industrial computer through the CPU module, the analog module, the digital conversion module, and the switch.

[0084] The control device 7 consists of three parts, namely a control box, an indicator light 72 and a high-definition intelligent LED display screen 71.

[0085] The control box includes power switches, circuits, and electrical components.

[0086] The indicator lights 72 include a power indicator light, a run indicator light, a stop indicator light, and an alarm indicator light.

[0087] The 71-screen HD smart LED display includes the main screen, parameter settings, and real-time monitoring. It can be set up and viewed locally or remotely from a computer in the main control room.

[0088] The main screen includes a flow chart of the intelligent sample loading device of the denitrification catalyst pilot test bench, which contains corresponding touch buttons, including a remote local switching button, a one-touch start button, an emergency stop button, a stop button and a manual control button for the operation of each component (for local manual control).

[0089] Parameter settings include setting the hydraulic pressure intensity, leak detection air supply pressure, reactor leak detection pressure lower limit and the pressure intensity of the automatic sealing device, and coordinating with the pressure sensor feedback to implement the sealing of the inner sleeve and the flue gas pipeline, leak detection air supply and check whether it is qualified, and automatic sealing of the catalyst in the inner sleeve.

[0090] Real-time monitoring can monitor the current hydraulic pressure intensity and the pressure intensity of the automatic sealing device during catalyst testing, thereby providing feedback on the quality of the equipment.

[0091] Beneficial effects:

[0092] The test bench disclosed in the present invention has a high degree of automation integration. Compared with the traditional test bench detection, each sample loading requires 2-3 people, transportation, manual wrapping and sealing, manual leak detection, manual bolt sealing, etc., which can realize the full process of automatic opening, sample loading, sealing and leak detection, replacing a large amount of manual work and improving work efficiency.

[0093] Wide scope of application: The present invention is applicable to the detection of denitrification catalysts with different cross-sectional sizes. The sealing method of the device is to achieve sealing through the feedback of the pressure generated after the high-temperature sealing gasket contacts the catalyst. Compared with the catalyst detection of the traditional test bench, it is necessary to wrap and seal the end face of the catalyst multiple times, the manual operation workload is large, and the sealing effect may not be ideal.

[0094] Complete operation monitoring system: This device can monitor the operating status of each component of the pilot test bench in real time, discover equipment problems in time, and ensure the accuracy of the test. Compared with traditional detection test benches, it is difficult to discover component problems in the operating state, resulting in air leakage in the test bench and inaccurate test data.

[0095] Comprehensive overload protection: Compared with traditional test benches, this device can prevent hydraulic overpressure through parameter settings, which may cause damage to the press, oil leakage, or failure to seal, and prevent leak detection and inflation overfilling, which may cause the detection system to alarm and trip, affecting the test of the pilot test bench.

[0096] High safety: The device improves safety, avoids injuries from bumps, burns, smashes, inhalation of harmful glass fibers (manual sealing materials), and eliminates the risk of collision between equipment. Compared with traditional test benches that require screw fixation, hoisting, and wrapping with glass fiber tapes, there is a risk of bumps, burns, smashes, and inhalation of harmful glass fibers.

[0097] In short, this device is an intelligent sample loading device for the pilot test bench of denitrification catalyst, which is efficient, safe and stable.

[0098] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present disclosure, but the present disclosure is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and substance of the present disclosure, and these modifications and improvements are also considered to be within the scope of protection of the present disclosure.
