Description

Technical Field

[0001] This invention relates to the field of coal flow monitoring technology, and in particular to a simulation monitoring device for visualizing coal flow during coal bunker unloading. Background Technology

[0002] Boiler combustion optimization is key to improving power plant efficiency and energy utilization, which relies on accurately understanding the type and quality of coal fed into the furnace. However, coal, as a special bulk material, has complex characteristics including uneven particle size distribution, diverse particle shapes, and significant differences in properties (including bituminous coal, anthracite, lignite, etc.). Although the coal quality characteristics at the raw coal bunker inlet can be obtained through manual testing and rapid coal quality testing technology, the large volume of raw coal bunkers and the common practice of blending in coal-fired power plants to improve economic efficiency often result in the storage of coal products from different time periods and batches within the bunker. Furthermore, in reality, coal bunker discharge ports often have two conveyor belts corresponding to two discharge ports, easily forming complex coal peak distribution patterns. This makes it difficult to accurately control the flow characteristics and mixing state of the material, and to obtain real-time coal quality characteristics entering the furnace from the raw coal bunker outlet. Consequently, it cannot provide precise guidance for combustion adjustments, which has become one of the core challenges faced by coal-fired power plants. Summary of the Invention

Detailed Implementation

[0018] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0019] The following is for reference. Figures 1-5 A simulation monitoring device 100 for visualizing coal flow unloading from a coal bunker, according to an embodiment of the present invention, is described.

[0020] like Figure 1 As shown, the simulation monitoring device 100 for visualizing coal flow unloading from a coal bunker according to an embodiment of the present invention includes: a first support 10, a first hopper 20, and a visualization device 50. The first hopper 20 is disposed on the first support 10 and has a receiving cavity and a first inlet 24 and a first outlet 25 communicating with the receiving cavity. The visualization device 50 is configured to collect and record images of material flow inside the first hopper 20.

[0021] The first support 10 provides a stable installation foundation and support structure for the first silo 20, which is used to bear the weight of the first silo 20 and its internal materials, and to ensure that the relative position of the first silo 20 in space is fixed. The first silo 20 is mainly used to simulate the storage and unloading environment of a real coal bunker. Its internal cavity is used to temporarily store materials to be unloaded. The first inlet 24 is mainly used to supply materials into the first silo 20, and the first outlet 25 is mainly used to discharge materials from the first silo 20.

[0022] The visualization device 50 can capture the dynamic images inside the first hopper 20 in real time, clearly showing the complete flow trajectory of the material from the inlet to the outlet. This allows operators to intuitively see the flow pattern, mixing pattern and physical characteristics of the material during unloading, and then predict the quality of the coal discharged from the hopper based on its shape and characteristics, providing an intuitive basis for combustion optimization.

[0023] It should be noted that the dimensions of the first silo 20 are based on a semi-scaled physical model of the raw coal silo of a coal-fired power plant with a geometric scale of 1:10 to 1:30.

[0024] According to an embodiment of the present invention, the simulated monitoring device 100 for the coal flow of the coal bunker during unloading can collect images of the coal flow in real time by setting up a visualization device 50. This allows for clear observation and analysis of the flow pattern, mixing law and physical characteristics of the coal during unloading, and can then predict the quality of the coal in the bunker, providing an intuitive basis for combustion optimization.

[0025] According to some embodiments of the present invention, the first hopper 20 is made of high-transparency plexiglass. The high transparency ensures that the coal flow state inside the first hopper 20 is fully visible, allowing operators to directly observe particle distribution, uneven flow, and segregation during the unloading process, providing a clear visual basis for analyzing coal flow characteristics.

[0026] Optionally, the thickness of the first hopper 20 is ≥15mm, the light transmittance is >90%, the flatness is ≤0.1mm / m, and the surface hardness is ≥7H. This ensures both the structural strength of the first hopper 20 and its visual appeal.

[0027] For example, the thickness of the first hopper 20 can be 15mm, 16mm, 17mm or more; the light transmittance can be 91%, 93%, 95% or more; the flatness can be 0.02mm / m, 0.04mm / m, 0.06mm / m, 0.08mm / m or 0.1mm / m; and the surface hardness can be 7H, 8H, 9H or more.

[0028] According to some embodiments of the present invention, such as Figure 1As shown, the visualization device 50 includes a camera and a receiver. The camera is located outside the first silo 20 and is used to acquire images of the material flow inside the first silo 20. The camera and the receiver are communicatively connected. The high-speed camera technology can clearly capture the details of the rapidly flowing coal flow, including particle trajectories, instantaneous flow unevenness, and local blockages, thus providing high-precision image data support for in-depth analysis of the coal flow dynamics. The receiver can adjust the frame rate parameters of the camera to ensure clear capture of the coal flow movement.

[0029] It should be noted that the camera equipment can also perform slow-motion tracking and analysis on the recorded images.

[0030] According to some embodiments of the present invention, such as Figure 2 As shown, the simulation monitoring device 100 also includes a first control valve 60, which is located at the first discharge port 25 of the first silo 20 and is used to control the opening and closing of the first discharge port 25. Specifically, the first control valve 60 can quickly cut off or restore the material flow as needed, thereby achieving precise control of the monitoring status of the simulation monitoring device 100, ensuring that the material supply is turned on when data collection is required and that it is turned off in time after monitoring is completed, avoiding ineffective operation, and thus ensuring the accuracy and effectiveness of the monitoring data.

[0031] According to some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the first silo 20 includes three interconnected sections: a first silo section 21, a second silo section 22, and a third silo section 23. These sections are arranged vertically from top to bottom. The horizontal cross-sectional area of ​​the first silo section 21 remains constant, while the horizontal cross-sectional areas of the second and third silo sections 22 and 23 gradually decrease vertically from top to bottom. The inner wall of the third silo section 23 is formed as an inwardly convex arc surface. It can be understood that the first silo 20 includes a cuboid at the top, a frustum in the middle, and a hyperbolic section at the bottom. The combination of the cuboid, frustum, and hyperbolic section can accurately reproduce the internal geometry of an actual coal silo, thereby ensuring that the simulated unloading flow trajectory is highly consistent with actual working conditions, thus improving the reliability and reference value of the monitoring data.

[0032] It should be noted that the first hopper section 21 and the second hopper section 22 are detachably connected, and the second hopper section 22 and the third hopper section 23 are detachably connected.

[0033] It should be noted that the first discharge port 25 is formed at the bottom of the third hopper section 23, and the first control valve 60 is a pull-out baffle.

[0034] According to some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the simulation monitoring device 100 further includes: a second support 30 and a second hopper 40. The second hopper 40 is mounted on the second support 30 and is used to store materials. The second hopper 40 has a second discharge port 41. In the vertical direction, the first hopper 20 is arranged below the second hopper 40, and the second discharge port 41 is connected to the first inlet port 24. Specifically, the second support 30 is used to support the second hopper 40 and provide installation space for the second hopper 40. The second hopper 40 is mainly used to store materials so that the first hopper 20 can be continuously replenished while unloading, thereby maintaining a dynamic balance between the feeding speed and the unloading speed. This ensures that the first hopper 20 maintains a stable flow state during the simulated unloading process, effectively avoiding experimental errors caused by structural deformation or flow turbulence, and improving the accuracy and repeatability of monitoring data.

[0035] In addition, the second hopper 40 overcomes the problem of manual continuous loading, thereby reducing testing time and labor costs.

[0036] Optionally, the simulation monitoring device 100 shall run for no less than 3 minutes.

[0037] According to some embodiments of the present invention, the simulation monitoring device 100 further includes a second control valve, which is arranged at the second discharge port 41 and is used to control the opening and closing of the second discharge port 41. Specifically, the second control valve can control the opening and closing of the second discharge port 41 and the size of the opening to realize the flow and disconnection of materials and the flow rate of the packing, thereby realizing precise adjustment and automated control of the material supply of the first silo 20 and ensuring the stability of subsequent monitoring.

[0038] According to some embodiments of the present invention, such as Figures 1-3 As shown, both the first support 10 and the second support 30 are equipped with brakeable casters 90 at their bottoms. That is, both the first support 10 and the second support 30 are movable. In other words, this embodiment can achieve convenient movement and position adjustment of the entire device through the casters 90. This makes it easy to quickly deploy and reposition the simulation monitoring device 100 in different sites or experimental scenarios, thereby improving the operational convenience and experimental efficiency of the simulation monitoring device 100.

[0039] It should be noted that there is no connection between the second support 30 and the first support 10. Therefore, the setting of the moving wheel 90 can also flexibly adjust the position of the packing, thereby simulating the coal flow mixing state under different feeding conditions, which can effectively improve the simulation flexibility and applicability of the simulation monitoring device 100.

[0040] According to some embodiments of the present invention, the first hopper 20 and the first support 10 are detachably connected, which facilitates the assembly and maintenance of the first hopper 20 and the first support 10.

[0041] According to some embodiments of the present invention, a first positioning protrusion is formed on one of the first hopper 20 and the first support 10, and a first positioning groove is formed on the other. The first positioning protrusion is positioned and engaged within the first positioning groove. It is understood that when the first positioning protrusion is formed on the first hopper 20, the first positioning groove is formed on the first support 10; conversely, when the first positioning groove is formed on the first hopper 20, the first positioning protrusion is formed on the first support 10. The engagement of the positioning groove and the positioning protrusion can define the installation position of the first hopper 20 and the first support 10, thereby further improving the assembly speed of the first hopper 20 and the first support 10.

[0042] According to some embodiments of the present invention, the second hopper 40 and the second support 30 are detachably connected, which facilitates the assembly and maintenance of the second hopper 40 and the second support 30.

[0043] According to some embodiments of the present invention, a second positioning protrusion is formed on one of the second hopper 40 and the second support 30, and a second positioning groove is formed on the other. The second positioning protrusion is positioned and engaged within the second positioning groove. It is understood that when the second positioning protrusion is formed on the second hopper 40, the second positioning groove is formed on the second support 30; conversely, when the second positioning groove is formed on the second hopper 40, the second positioning protrusion is formed on the second support 30. The engagement of the positioning groove and the positioning protrusion can define the installation position of the second hopper 40 and the second support 30, thereby further improving the assembly speed of the second hopper 40 and the second support 30.

[0044] According to some embodiments of the present invention, such as Figure 1 and Figure 5 As shown, the simulation monitoring device 100 also includes a receiving device 70, which is located below the first hopper 20 and is used to receive the material discharged from the first discharge port 25. This effectively prevents material from spilling onto the ground, thus facilitating the recycling and cleaning of the material after testing. It should be noted that the volume of the receiving device 70 is greater than or equal to the volume of the second hopper 40.

[0045] Optionally, the bottom of the receiving device 70 is provided with pulleys 80, which facilitates the convenient movement and position adjustment of the receiving device 70, thereby improving the ease of operation of the simulation testing device.

[0046] It should be noted that the simulation monitoring device 100 is composed of a first support 10, a first hopper 20, a second support 30, a second hopper 40, a visualization device 50, a first control valve 60, a second control valve, and a receiving device 70, all connected together. In other words, the simulation monitoring device 100 is a modular design. This modular design not only significantly reduces the size of individual components, greatly facilitating long-distance transportation and on-site handling, but also significantly simplifies the on-site assembly process, making installation and disassembly operations extremely convenient and efficient. Furthermore, the fully modular connection method completely eliminates traditional on-site welding processes, making the entire installation process cleaner, safer, and more environmentally friendly, and effectively avoiding potential harm to the health of operators that welding operations may cause.
