Description

Technical Field

[0001] This utility model relates to the technical field of carbon emission monitoring devices, and more specifically, to a real-time carbon footprint monitoring and carbon emission early warning device for converter steelmaking. Background Technology

[0002] Converter steelmaking is a crucial step in the steel production process. Its basic principle involves pouring molten iron from the blast furnace into the converter, along with appropriate amounts of scrap steel and slag-forming materials. High-pressure oxygen is then blown into the converter from the top, causing a violent oxidation reaction of impurities in the molten iron, such as carbon, silicon, manganese, and phosphorus. The converter steelmaking process involves multiple complex chemical reactions, among which the oxidation of carbon is one of the main sources of carbon emissions. The carbon in the molten iron reacts with the blown-in oxygen to produce carbon dioxide; this is an irreversible chemical reaction, and as long as carbon participates in the reaction, carbon dioxide emissions will inevitably occur. Furthermore, carbon emissions from converter steelmaking exhibit phased and intermittent characteristics. In the initial blowing stage, as oxygen is introduced, elements such as silicon and manganese in the molten iron oxidize first, resulting in relatively low carbon emissions. In the middle stage of blowing, the oxidation reaction of carbon proceeds rapidly, causing carbon emissions to increase quickly and reach a peak. In the later stage of blowing, as the carbon content decreases, carbon emissions gradually decrease again. Moreover, converter steelmaking is conducted in batches, with a certain interval between each batch. This means that carbon emissions are not generated continuously and stably, but rather intermittently, thus requiring real-time monitoring of carbon emissions.

[0003] While the steel industry actively explores carbon reduction pathways, carbon footprint monitoring and carbon emission early warning technologies are crucial for achieving carbon reduction targets. However, traditional monitoring methods often rely on manual data collection combined with simple calculation models, which are highly susceptible to human error, such as reading errors and recording mistakes. When manually reading instrument data, discrepancies between the collected data and actual energy consumption can arise due to timing deviations and visual errors. Furthermore, these methods cannot reflect the dynamic changes in enterprise carbon emissions in a timely manner. If an abnormal increase in carbon emissions occurs during production, it is difficult to detect and take timely corrective measures, potentially leading to a prolonged period of high carbon emissions for the enterprise, which is detrimental to achieving carbon reduction targets. Utility Model Content

[0004] The main purpose of this invention is to provide a real-time carbon footprint monitoring and carbon emission early warning device for converter steelmaking, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A real-time carbon footprint monitoring and carbon emission early warning device for converter steelmaking includes a detection component. The detection component includes a flow tube with connectors at both ends. A detection tube is fixedly connected to the side of the flow tube. A fixing frame is fixedly connected to the outer surfaces of the flow tube and the detection tube. The flow tube is fixedly connected to the detection tube via the fixing frame. Guide tubes are fixedly connected to both ends of the detection tube, with one end of each guide tube connected to the flow tube. A display is fixedly connected to the upper end of the detection tube. A gas analyzer is fixedly connected to the inner wall of the upper end of the detection tube. The display is electrically connected to the gas analyzer. An audible and visual alarm is fixedly connected to the top of the detection tube. A pulse cleaning device is installed inside the detection tube. A filter assembly is fixedly installed inside the detection tube. A vibration device is fixedly connected to the top of the pulse cleaning device. A fixing frame is fixedly connected to the lower end of the inside of the detection tube.

[0006] Preferably, the filter assembly includes a movable plate, with multiple striking balls fixedly connected to the top perimeter of the movable plate, a movable rod fixedly connected to the bottom of the movable plate, a vibration spring movably sleeved on the outer surface of the movable rod, multiple filter bag frames fixedly sleeved inside the movable plate, filter mesh bags sleeved on the outer surface of the multiple filter bag frames, and support rollers rotatably installed at both ends of the top of the movable plate.

[0007] Preferably, the movable plate is movably sleeved inside the detection tube, the movable rod is movably sleeved inside the fixed frame, and the vibration spring is located between the fixed frame and the movable plate.

[0008] Preferably, the pulse cleaning device includes a support frame and a side frame. The support frame is fixedly installed inside the upper end of the detection tube, and the side frame is fixedly installed on the outer surface of the detection tube. A blow pipe is fixedly connected to the bottom of the support frame, and an air bag is fixedly connected to the top of the side frame. A pulse switching valve is fixedly connected to the output end of the air bag, and one end of the pulse switching valve is connected to the blow pipe. The striking ball is located at the bottom of the support frame.

[0009] Preferably, the vibration device includes a rotating motor, the output end of which is fixedly connected to a rotating shaft, the bottom of which is fixedly connected to a rotating plate, and top blocks fixedly connected to both ends of the bottom of the rotating plate.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a detection tube, a display, and a gas analyzer, the carbon emissions of flue gas are monitored by the gas analyzer, and the time and carbon emission content are displayed on the display. When the carbon emission content is higher than the threshold, an audible and visual alarm is triggered by an electrical signal. The gas analyzer monitors the flue gas in real time and dynamically monitors the changes in carbon emissions in the flue gas, which is conducive to achieving carbon emission reduction targets. 2. By setting up filter bags, the filter bags intercept solid particles in the flue gas, preventing solid particles from adhering to the outer surface of the gas analyzer and affecting the monitoring accuracy of the gas analyzer. 3. By setting up a pulse cleaning device and a vibration device, the high-pressure gas inside the air tank is sprayed out through the blow pipe, causing the high-pressure gas to blow backward through the filter bag. At the same time, the rotating motor controls the rotating plate to rotate at the bottom of the support frame. Utilizing the inclined surface of the top block, the moving plate is raised by the reaction force of the vibration spring, and the striking ball hits the bottom of the support frame, causing the filter bag to vibrate. The solid particles on the outer surface of the filter bag are shaken off by gravity and airflow and flow back into the interior of the flow pipe, thus achieving automatic cleaning.

[0014] As attached Figure 1 To be continued Figure 5 As shown, an embodiment of this utility model provides a real-time carbon footprint monitoring and carbon emission early warning device for converter steelmaking, including a detection component 1.

[0015] Specifically, the upper and lower ends of the detection tube 14 are connected to the flow tube 11 through the guide tube 15. The flue gas enters the interior of the flow tube 11 through the lower end and flows out through the upper end of the flow tube 11. A portion of the flue gas enters the interior of the detection tube 14 through the guide tube 15 at the lower end and flows out through the guide tube 15 at the upper end of the flow tube 11. During this process, the carbon emission of the flue gas is monitored by the gas analyzer 17, and the time and carbon emission content are displayed on the display 16. When the carbon emission content is higher than the threshold, the audible and visual alarm 18 is activated by an electrical signal. The gas analyzer 17 monitors the flue gas in real time and dynamically monitors the changes in carbon emissions in the flue gas, which is conducive to the achievement of carbon emission reduction targets.

[0016] like Figure 3 As shown, the filter assembly 3 includes a movable plate 31. Multiple striking balls 34 are fixedly connected around the top of the movable plate 31. A movable rod 32 is fixedly connected to the bottom of the movable plate 31. A vibration spring 33 is movably sleeved on the outer surface of the movable rod 32. Multiple filter bag frames 35 are fixedly sleeved inside the movable plate 31. Filter mesh bags 36 are sleeved on the outer surface of the multiple filter bag frames 35. Support rollers 37 are rotatably installed at both ends of the top of the movable plate 31.

[0017] The movable plate 31 is movably sleeved inside the detection tube 14, the movable rod 32 is movably sleeved inside the fixed frame 19, and the vibration spring 33 is located between the fixed frame 19 and the movable plate 31.

[0018] Specifically, the filter bag 36 intercepts solid particles in the flue gas, preventing solid particles from adhering to the outer surface of the gas analyzer 17 and affecting the monitoring accuracy of the gas analyzer 17.

[0019] like Figure 4 As shown, the pulse cleaning device 2 includes a support frame 21 and a side frame 23. The support frame 21 is fixedly installed inside the upper end of the detection tube 14, and the side frame 23 is fixedly installed on the outer surface of the detection tube 14. A blow pipe 22 is fixedly connected to the bottom of the support frame 21, and an air tank 24 is fixedly connected to the top of the side frame 23. A pulse switching valve 25 is fixedly connected to the output end of the air tank 24. One end of the pulse switching valve 25 is connected to the blow pipe 22, and the striking ball 34 is located at the bottom of the support frame 21.

[0020] like Figure 5 As shown, the vibration device 4 includes a rotating motor 41, the output end of which is fixedly connected to a rotating shaft 42, the bottom of which is fixedly connected to a rotating plate 43, and both ends of the bottom of the rotating plate 43 are fixedly connected to top blocks 44. The bottom of the top blocks 44 is provided with an inclined surface. The rotating motor 41 is fixedly installed on the top of the support frame 21, the rotating plate 43 is rotatably installed below the support frame 21, and the top blocks 44 are movably installed on the top of the support roller 37.

[0021] When cleaning the filter bag 36, the pulse switch valve 25 and the rotary motor 41 are opened. The high-pressure gas inside the air tank 24 is sprayed out through the blow pipe 22, causing the high-pressure gas to blow in the opposite direction through the filter bag 36. At the same time, the rotary motor 41 controls the rotating plate 43 to rotate at the bottom of the support frame 21. Using the inclined surface of the top block 44, when the top block 44 rotates to the top of the support roller 37, the top block 44 pushes the top of the support roller 37, causing the movable plate 31 to descend. The movable rod 32 moves inside the fixed frame 19, and the vibration spring 33 is compressed. When the top block 44 passes the top of the support roller 37, the reaction force of the vibration spring 33 causes the movable plate 31 to rise. The striking ball 34 hits the bottom of the support frame 21, causing the filter bag 36 to vibrate. As a result, the solid particles on the outer surface of the filter bag 36 are affected by gravity and airflow and flow back into the interior of the flow pipe 11. The solid particles are then discharged from the top of the flow pipe 11 along with the flue gas and processed in subsequent processes.

[0022] The working process of this utility model is as follows: Flue gas enters the interior of the flow pipe 11 through the lower end and flows out through the upper end of the flow pipe 11. A portion of the flue gas enters the interior of the detection pipe 14 through the guide pipe 15 at the lower end.

The filter bag 36 intercepts the solid particles in the flue gas and flows out through the guide pipe 15 at the upper end of the flow pipe 11. During this process, the carbon emission of the flue gas is monitored by the gas analyzer 17, and the time and carbon emission content are displayed on the display 16. When the carbon emission content is higher than the threshold, the audible and visual alarm 18 is activated by an electrical signal. When cleaning the filter bag 36, the pulse switch valve 25 and the rotary motor 41 are opened. The high-pressure gas inside the air tank 24 is sprayed out through the blow pipe 22, causing the high-pressure gas to blow in the opposite direction through the filter bag 36. At the same time, the rotary motor 41 controls the rotating plate 43 to rotate at the bottom of the support frame 21. Using the inclined surface of the top block 44, when the top block 44 rotates to the top of the support roller 37, the top block 44 pushes the top of the support roller 37, causing the movable plate 31 to descend. The movable rod 32 moves inside the fixed frame 19, and the vibration spring 33 is compressed. When the top block 44 passes the top of the support roller 37, the reaction force of the vibration spring 33 causes the movable plate 31 to rise. The striking ball 34 hits the bottom of the support frame 21, causing the filter bag 36 to vibrate. As a result, the solid particles on the outer surface of the filter bag 36 are affected by gravity and airflow and flow back into the interior of the flow pipe 11. The solid particles are then discharged from the top of the flow pipe 11 along with the flue gas and processed in subsequent processes.
