Description

Technical Field

[0001] This invention relates to the field of monitoring technology, and in particular to a gas-solid fluidized bed monitoring method and system based on vibration monitoring status. Background Technology

[0002] Fluidized beds are a common type of reaction vessel in industrial production, widely used in industries such as chemical, energy, and pharmaceutical. The fluidization state of a fluidized bed directly affects the reaction activity and the formation of reactants, making it the most important monitoring object in fluidized bed production process control.

[0003] However, due to the complexity of the fluidization mechanism and the variability of fluidization phenomena, coupled with the high-temperature and high-pressure operating environment inside the fluidized bed, monitoring the fluidization state of the fluidized bed becomes extremely difficult. Existing monitoring technologies include differential pressure monitoring (such as patents CN112212322A and CN113155217A) and optical monitoring (such as patents CN102455218A and CN116026792A).

[0004] Differential pressure monitoring requires piping connected to pressure sensors inside the fluidized bed. However, in actual production, fine solid particles in the gas-solid fluidized bed can easily clog the piping, leading to distorted measurement results. Furthermore, the number of measurement points available for differential pressure monitoring is very limited.

[0005] Optical monitoring methods require the installation of optical probes inside the fluidized bed, relying primarily on visual images or the reflection of light waves for measurement. However, due to the high temperature, high pressure, and corrosiveness of the fluidized bed environment, wear from solid particles can severely damage the optical probes, resulting in very short maintenance and replacement cycles. Furthermore, during the fluidized bed reaction process, internal turbulence and turbidity significantly interfere with light propagation, leading to inaccurate measurements.

[0006] In summary, existing fluidized bed condition monitoring methods cannot meet the requirements for monitoring accuracy and reliability of fluidized beds. Summary of the Invention

[0007] The technical problem to be solved by this invention is to address the above-mentioned shortcomings of the prior art by proposing a gas-solid fluidized bed monitoring method and system based on vibration monitoring status. This method is unaffected by the erosion and interference of the internal reaction environment of the fluidized bed reactor, and can achieve long-term, stable, reliable, and accurate measurement of the fluidized bed.

[0008] In a first aspect, the present invention provides a gas-solid fluidized bed monitoring method based on vibration monitoring status, the method comprising the following steps:

[0009] Step S1: Determine the vibration monitoring location based on the spatial location of the fluidized bed;

[0010] Step S2: Based on the vibration monitoring locations, deploy N sets of vibration sensors; N is a natural number greater than 1.

[0011] Step S3: Obtain the amplitude and frequency of all vibration sensors;

[0012] Step S4: Input the amplitude and frequency of the vibration sensor into the three-dimensional coordinate system to obtain the amplitude and frequency in the XYZ axes of the three-dimensional coordinate system, so as to complete the gas-solid fluidized bed monitoring based on the vibration monitoring status.

[0013] Furthermore, if N=5, then deploying N sets of vibration sensors specifically means deploying five sets of vibration sensors;

[0014] The five sets of vibration sensors are as follows: the first set of vibration sensors is arranged on the outer wall circumference above the plane where the gas distributor is located; the second set of vibration sensors is arranged on the outer wall circumference above the plane where the fluidized bed surface is located; the third set of vibration sensors is arranged on the outer wall circumference above the plane where the cyclone separator inlet is located; the fourth set of vibration sensors is arranged on the outer wall circumference above the plane where the outlet pipe is located; and the fifth set of vibration sensors is arranged on the outer wall circumference between the gas distributor and the fluidized bed surface.

[0015] After step S4, the method further includes step S5;

[0016] Step S5: Evaluate the fluidization state and fluidization uniformity of the fluidized bed based on the amplitude and frequency in the XYZ axes of the three-dimensional coordinate system.

[0017] Step S5 specifically includes:

[0018] Based on the amplitude and frequency of the first set of vibration sensors along the XYZ axes in the three-dimensional coordinate system, the flow state and fluidization uniformity of the gas diffused through the distributor are evaluated; and...

[0019] Based on the amplitude and frequency of the second set of vibration sensors along the XYZ axes in the three-dimensional coordinate system, the flow state and fluidization uniformity of the fluidized bed are evaluated; and...

[0020] Based on the amplitude and frequency of the third set of vibration sensors along the XYZ axes in the three-dimensional coordinate system, the flow state and fluidization uniformity at the cyclone separator inlet are evaluated; and,

[0021] Based on the amplitude and frequency of the fourth set of vibration sensors along the XYZ axes in the three-dimensional coordinate system, the flow state and fluidization uniformity of the fluid during the outflow process are evaluated; and,

[0022] The flow state and flow uniformity during gas-solid mixing reaction are evaluated based on the amplitude and frequency of the fifth set of vibration sensors along the XYZ axes in the three-dimensional coordinate system.

[0023] Secondly, the present invention provides a gas-solid fluidized bed monitoring system based on vibration monitoring status, the system comprising:

[0024] N sets of vibration sensors are used to monitor vibration, where N is a natural number greater than 1;

[0025] A gateway device is used to acquire vibration data from the vibration sensor in real time; the vibration data includes amplitude and frequency.

[0026] An industrial control computer is connected to the gateway device via a network to input the amplitude and frequency of the vibration sensor into a three-dimensional coordinate system, thereby obtaining the amplitude and frequency in the XYZ axes of the three-dimensional coordinate system to complete the gas-solid fluidized bed monitoring based on the vibration monitoring status.

[0027] Furthermore, the N sets of vibration sensors are five sets of vibration sensors;

[0028] The five sets of vibration sensors are as follows: the first set of vibration sensors is arranged on the outer wall circumference above the plane where the gas distributor is located; the second set of vibration sensors is arranged on the outer wall circumference above the plane where the fluidized bed surface is located; the third set of vibration sensors is arranged on the outer wall circumference above the plane where the cyclone separator inlet is located; the fourth set of vibration sensors is arranged on the outer wall circumference above the plane where the outlet pipe is located; and the fifth set of vibration sensors is arranged on the outer wall circumference between the gas distributor and the fluidized bed surface.

[0029] The five sets of vibration sensors are then fitted with thermally conductive aluminum oxide shells and fixed to the outer circumferential surface of the gas-solid fluidized bed using magnetic attraction or thermal insulation nails.

[0030] The beneficial effects of this invention are:

[0031] 1. This invention uses a vibration sensor to measure on the outer wall of the fluidized bed, which is not affected by the erosion and interference of the internal reaction environment of the fluidized bed reactor, and can achieve long-term stable and reliable accurate measurement.

[0032] 2. Compared with optical and differential pressure monitoring methods, vibration monitoring is less susceptible to internal turbulence and particle interference, thus ensuring measurement accuracy.

[0033] 3. The installation of this invention is relatively simple because the vibration sensor does not need to directly contact the fluidized bed, reducing the impact of equipment failure on production.

[0034] 4. By arranging multiple sets of vibration sensors at key locations, this invention can comprehensively capture vibration information inside the fluidized bed and provide more accurate fluidization state feedback.

[0035] 5. This invention can acquire amplitude and frequency data in real time and quickly convert them into information in a three-dimensional coordinate system, thereby improving the monitoring and response speed of fluidized bed status.

[0036] 6. This invention can analyze data and diagnose faults using amplitude and frequency data, thereby better supporting the optimization of the production process.

[0037] 7. This invention can withstand the effects of high temperature, high pressure and corrosive environment, reduce the wear and maintenance frequency of monitoring equipment, and at the same time, the number of sensors is multiple, avoiding the impact of single point failure on monitoring results and improving data reliability.

[0038] 8. This invention is applicable to various types of gas-solid fluidized beds, and can effectively monitor particle size, density, and fluidization characteristics.

[0039] 9. This invention, through a three-dimensional coordinate system, can clearly understand the vibration characteristics of XYZ, facilitating the analysis of the dynamic behavior and reaction characteristics of fluidized beds.

[0040] 10. This invention can be flexibly applied to different types of gas-solid fluidized beds, has strong adaptability, and is easy to use in various industrial applications.

[0041] 11. This invention adds a thermally conductive and heat-dissipating shell of alumina material to the outside of the sensor, giving the sensor excellent high-temperature resistance, chemical resistance, and wear resistance, effectively avoiding corrosion and wear from the reaction environment and ensuring long-term use of the equipment. At the same time, the alumina heat dissipation shell has excellent thermal conductivity, which can promptly transfer the heat absorbed internally, thereby significantly improving the accuracy of monitoring and reflecting the true reaction state of the fluidized bed.

[0042] 12. This invention uses magnetic or heat-insulating nail fixing methods, which, compared with traditional screw fixing, avoids heat loss caused by drilling holes or excessively deep holes in the fluidized bed cylinder, making installation simpler and applicable to a wide range of scenarios.

[0043] 13. This invention enables three-dimensional online monitoring of the fluidized bed's operating status, accurately locating the spatial position of abnormal points in real time, providing scientific guidance for on-site troubleshooting and maintenance, and significantly improving maintenance and inspection efficiency.

[0044] 14. This invention provides a reliable monitoring and evaluation method, which realizes effective quantitative evaluation of the fluidized bed reaction state and provides a scientific and intuitive data model for operation and maintenance personnel to understand the operating status of the fluidized bed.

[0045] 15. This invention is not only applicable to gas-solid fluidized bed reactors, but can also be extended to other monitoring application scenarios that are subject to environmental constraints, and has strong market potential and application value. Attached Figure Description

[0550] like Figure 1 As shown, the implementation process of this embodiment includes the following seven steps:

[0551] Step 1: Arrange several vibration sensors on the outer wall of the fluidized bed, with denser arrangement for key areas of interest. Specifically (e.g.) Figure 1 Vibration sensors S1 to S5 are arranged above the plane where the gas distributor is located (3); vibration sensors S14 to S21 are arranged above the plane where the fluidized bed surface is located (2); vibration sensors S22 to S24 are arranged above the plane where the cyclone separator inlet is located (4); vibration sensors S25 to S26 are arranged above the plane where the outlet pipe is located (4); vibration sensors S6 to S13 are evenly arranged in a grid between the gas distributor and the fluidized bed surface (3).

[0552] Step 2: Accurately input the Cartesian coordinate data of the spatial location of each sensor into the three-dimensional coordinate system.

[0553] Step 3: Operate the fluidized bed stably and reach the designed standard production capacity. Record the amplitude Am (1-26), frequency Fre (1-26), and direction data Dir (1-26) returned by each sensor during the production process. Correspond one-to-one with the coordinate system data to form a standard fluidized state database array.

[0554] Step 4: Based on the coordinates of the monitoring points, aggregate and compare the frequency Fre (i~n) and amplitude Am (i~n) of monitoring points at the same or similar heights to determine the degree of data concentration. Calculate the average measured amplitude using equations 121~124. and standard deviation Measure the average frequency and standard deviation This is used to evaluate the uniformity of the reaction in the current horizontal direction within the fluidized bed.

[0565]

[0566] Step 7: Based on the calculation results of Step 6, evaluate the fluidization state within the fluidized bed:

[0567] First, determine the deviation of the average measurement frequency. And the degree of deviation of the average amplitude measurement Assess whether the current fluidization state conforms to the design fluidization state. If either of the two deviations exceeds a set threshold, the current fluidization state is deemed not to conform to the design fluidization state, and troubleshooting and maintenance should be carried out in conjunction with other production monitoring data. Only when both deviations are less than the set thresholds is the current fluidization state deemed to conform to the design fluidization state.

[0568] If the current fluidization state meets the design fluidization state, then the deviation can be determined based on the standard deviation of the measurement frequency. and the degree of deviation of the amplitude standard. Assess whether the current fluidization state is sufficiently uniform. If either of the two deviations exceeds a set threshold, the current fluidization uniformity is deemed not to meet the design fluidization uniformity, and troubleshooting and maintenance should be carried out in conjunction with other production monitoring data. Only when both deviations are less than the set thresholds is the current fluidization uniformity considered to meet the design fluidization uniformity.

[0569] Example 2:

[0570] like Figure 1 As shown, this embodiment provides a gas-solid fluidized bed monitoring system based on vibration monitoring status. The system includes:

[0571] N sets of vibration sensors are used to monitor the vibration of the gas-solid fluidized bed, where N is a natural number greater than 1;

[0572] A gateway device is used to acquire vibration data from the vibration sensor in real time; the vibration data includes amplitude and frequency.

[0573] An industrial control computer is connected to the gateway device via a network to input the amplitude and frequency of the vibration sensor into a three-dimensional coordinate system, thereby obtaining the amplitude and frequency in the XYZ axes of the three-dimensional coordinate system to complete the gas-solid fluidized bed monitoring based on the vibration monitoring status.

[0574] In this embodiment, the N sets of vibration sensors consist of five sets: a first set positioned on the outer wall circumference above the plane where the gas distributor is located; a second set positioned on the outer wall circumference above the plane where the fluidized bed surface is located; a third set positioned on the outer wall circumference above the plane where the cyclone separator inlet is located; a fourth set positioned on the outer wall circumference above the plane where the outlet pipe is located; and a fifth set positioned on the outer wall circumference between the gas distributor and the fluidized bed surface. These five sets of vibration sensors are strategically positioned at key locations on the outer wall of the fluidized bed, comprehensively covering the main process stages of the fluidized bed. The first set of sensors monitors the vibration of the gas distributor, helping to determine whether the gas flow is uniform and whether there is any blockage, thereby optimizing the gas distribution effect and improving production efficiency. The second set of sensors is arranged above the surface of the fluidized bed, monitoring the flow state of the fluidized bed, promptly identifying changes in particle fluidization characteristics, and preventing process abnormalities caused by uneven fluidization; it also monitors the flow conditions at the cyclone separator inlet to ensure that the particle flow characteristics of the feed meet design requirements. The fourth set of sensors on the outlet pipeline monitors the stability of fluid delivery and particle flow state. The fifth set of sensors can monitor vibration during gas-solid reactions. These five sets of sensors can collect a large amount of data, and through data analysis, identify the characteristics of normal operation and abnormal states, thus providing fundamental support for the intelligent and automated control of the system. In summary, placing the five sets of vibration sensors in these specific locations not only increases the comprehensiveness and effectiveness of monitoring but also improves the safety, stability, and operational efficiency of monitoring.

[0575] Five vibration sensors are fitted with thermally conductive alumina shells and then secured to the outer circumference of the gas-solid fluidized bed using either magnetic attachment or insulated nails. The alumina shells provide excellent high-temperature resistance, chemical resistance, and wear resistance, effectively preventing corrosion and abrasion from the reaction environment and ensuring long-term equipment use. Simultaneously, the alumina shells have excellent thermal conductivity, effectively transferring absorbed heat away, significantly improving monitoring accuracy and reflecting the true reaction state of the fluidized bed. Furthermore, the magnetic or insulated nail mounting methods, compared to traditional screw mounting, avoid heat loss caused by drilling holes or excessively deep holes in the fluidized bed cylinder, simplifying installation and making it suitable for a wide range of applications.

[0576] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
