Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of iron ore sintering equipment, and in particular to a high-efficiency iron ore sintering injection carbon reduction device. Background Technology
[0002] Against the backdrop of global advocacy for energy conservation, emission reduction, and sustainable development, the steel industry, as a key sector for energy consumption and carbon emissions, faces the critical challenge of optimizing and upgrading its production processes. High-efficiency iron ore sintering injection carbon reduction devices have emerged as a core component of the iron ore sintering process in steel production. These devices inject clean gaseous fuels such as natural gas and hydrogen, along with auxiliary media like steam, into the sintering bed. This changes the traditional sintering model, which relies solely on solid fuels for heating and reaction. While providing the necessary heat for the sintering process, the injected media participate in the chemical reaction, optimizing the combustion path and achieving multiple goals: reducing carbon consumption, improving energy efficiency, and reducing pollutant emissions. This has profound significance for promoting the green transformation of the steel industry.
[0003] Early iron ore sintering injection carbon reduction devices had a relatively basic structure, mainly consisting of simple injection pipelines and ordinary sintering mechanisms. The injection pipelines could only roughly deliver gaseous fuel to the surface of the sintering material layer, lacking precise control over the injection volume, position, and angle. This resulted in the injection medium failing to fully penetrate into the interior of the sintering material layer, limiting the contact area with solid fuel and iron ore particles, and failing to effectively replace solid fuel. The solid fuel replacement rate was extremely low. To solve this problem, existing devices have introduced advanced automated injection systems, equipped with high-precision flow control valves and multi-axis adjustable nozzles. The flow control valves can precisely adjust the flow in real time according to the sintering process parameters. The flow rate of the spraying medium is adjusted by multi-axis adjustable nozzles, which can flexibly change the spraying angle to ensure that the spraying medium evenly covers the material layer. However, although the existing equipment has significantly improved the spraying accuracy, in actual operation, due to the complexity of the sintering material layer, uneven particle size distribution and material bulk density differences, the flow resistance of the spraying medium in the material layer is variable. Although the nozzle can adjust the angle, in the face of this complex situation, the spraying medium still cannot stably and continuously penetrate into the material layer to fully compete and react with the solid fuel. This makes it difficult to break through a certain bottleneck in the replacement rate of solid fuel, and cannot meet the urgent needs of the steel industry to further reduce carbon emissions and increase the proportion of clean energy use.

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a high-efficiency iron ore sintering injection carbon reduction device, comprising an insulated box 1, a heat exchange box 3 connected to the top of the outer wall of the insulated box 1, a heat-resistant perforated plate 4 fixedly connected to the top of the inner wall of the insulated box 1, a plurality of natural gas nozzles 5 connected to the bottom of the heat-resistant perforated plate 4, an interface pipe 6 penetrating the heat insulated box 1 on the left side of the heat-resistant perforated plate 4, natural gas entering the heat-resistant perforated plate 4 through the interface pipe 6 and being ejected through the natural gas nozzles 5 above, thereby aiding combustion inside the box. Perforated partitions 7 are fixedly connected to the upper and lower sides of the inner wall of the heat exchange box 3, a plurality of cylinders 8 connected to adjacent sides of two perforated partitions 7, the perforated partitions 7 and the cylinders 8 creating a sealed space inside the heat exchange box 3, into which a large amount of pure water is added. A steam pipe 9 is connected to the right side of the heat exchange box 3, the other end of the steam pipe 9 penetrating the heat insulated box 1 and connected to a U-shaped pipe 10, a plurality of steam nozzles 11 connected to the outer wall of the U-shaped pipe 10, and combustion... The flue gas generated during combustion passes through the heat exchange box 3. The heated flue gas enters the cylinder 8 through the holes above the perforated partition 7, allowing the heated flue gas to be transferred to the pure water on the outside through the cylinder 8, raising its temperature and causing the water inside to be heated and turned into steam. The steam enters the U-shaped pipe 10 through the steam pipe 9, and finally is sprayed onto the inner middle layer area through the steam nozzle 11. A blower 12 is fixedly connected to the left side of the outer wall of the heat exchange box 1. One end of the blower 12 passes through the heat exchange box 1 and is connected to a fixed U-tube 13. The outer wall of the fixed U-tube 13 is connected to multiple air nozzles 14. By starting the blower 12, outside air is drawn through the fixed U-tube 13 and the air nozzles 14, increasing the oxygen content in the inner bottom layer. An exhaust pipe 15 is connected to the top of the heat exchange box 3. A hollow partition 16 is fixedly connected to the top of the inner wall of the heat exchange box 1. A cleaning and collection mechanism 2 is provided on the rear side of the outer wall of the heat exchange box 3. The cleaning and collection mechanism 2 is used to clean the impurities adsorbed above the bottom perforated partition 7.
[0033] Specifically, the perforated partition 7 and the cylinder 8 create a sealed space inside the heat exchange box 3. A large amount of pure water is added to this sealed space, and then connected to an external natural gas pipeline via an interface pipe 6. Natural gas enters the heat-resistant perforated plate 4 through the interface pipe 6 and is ejected through the natural gas nozzle 5 above, thus aiding internal combustion. The flue gas generated during combustion passes through the heat exchange box 3, and the heated flue gas enters the cylinder 8 through the perforations above the perforated partition 7. This heated flue gas is then transferred to the pure water outside the cylinder 8, raising its temperature and causing the water inside to be heated and converted into steam. The steam then enters the U-shaped pipe 10 through the steam pipe 9 and is finally sprayed onto the inner middle layer area through the steam nozzle 11. Furthermore, by activating the blower 12, outside air is drawn through the fixed U-shaped pipe 13 and air nozzle 14, increasing the oxygen content in the inner bottom layer. This, combined with the natural gas's support for internal combustion and the steam's reduction of internal carbon monoxide content, enhances combustion by increasing the oxygen content, thereby increasing the solid fuel substitution rate and reducing carbon monoxide emissions.
[0034] Reference Figure 4 , Figure 5 and Figure 6 The cleaning and collection mechanism 2 includes a servo motor 201. The front side of the servo motor 201 is fixedly connected to the rear side of the outer wall of the heat exchange box 3. The output end of the servo motor 201 passes through the heat exchange box 3 and is fixedly connected to a bevel gear 202. A hollow bevel gear 203 is meshed with the outer wall of the bevel gear 202. A drive gear 204 is fixedly connected to the top of the hollow bevel gear 203. A rack 205 is meshed with the front and rear sides of the outer wall of the drive gear 204. A scraper 206 is fixedly connected to the outer wall of the rack 205. A rotating plate 207 is rotatably connected to the bottom of the scraper 206. When the servo motor 201 is started, it carries... The rotating bevel gear 202 drives the hollow bevel gear 203 to rotate, which in turn drives the drive gear 204 to rotate, causing the outer rack 205 to move relative to the drive gear 205. This causes the scraper 206 to scrape off the impurities above the bottom hole partition 7. The scraped-off impurities fall on the rotating plate 207. A discharge port 208 is provided at the middle of the bottom of the inner wall of the heat exchange box 3. A collection box 209 is slidably connected to the inner wall of the scraper 206. When the rotating plate 207 comes above the discharge port 208, it will rotate due to its own gravity, causing the impurities above to fall into the collection box 209.
[0035] Specifically, after a period of use, a large amount of impurities will adhere to the top of the perforated partition 7 at the bottom. At this time, the servo motor 201 is started, which drives the bevel gear 202 to rotate, which in turn drives the hollow bevel gear 203 to rotate, and drives the drive gear 204 to rotate, causing the outer rack 205 to move relative to the drive gear 206, which in turn drives the scraper 206 to scrape off the impurities above the perforated partition 7 at the bottom. The scraped-off impurities will fall on the rotating plate 207. When the rotating plate 207 reaches the top of the discharge port 208, it will rotate due to its own gravity, causing the impurities above to fall into the collection box 209, thus completing the collection and cleaning of impurities and preventing the ventilation duct from being blocked.
[0036] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the heat insulation box 1 is fixedly connected with multiple L-shaped connecting blocks 17, which provide a stable connection base for the heat insulation box 1 to other components. The inner wall of the L-shaped connecting blocks 17 is fixedly connected with multiple fixing bolts 18, which are key components to ensure the tight connection between the L-shaped connecting blocks 17 and other components. An observation window 19 is opened on the front side of the outer wall of the heat insulation box 1, which provides the operator with a way to directly observe the internal condition of the heat insulation box 1. An outer frame 20 is fixedly connected to the outer wall of the observation window 19, which plays an important role in protecting the observation window 19. A pressure gauge 21 is fixedly connected to the front right side of the outer wall of the heat exchange box 3, which allows the operator to easily read the pressure value during daily operation. A temperature sensor 22 is fixedly connected to the right side of the outer wall of the heat insulation box 1, which can accurately sense the temperature changes inside the heat insulation box 1.
[0037] Specifically, the L-shaped connecting block 17 provides a stable connection base for the insulation box 1 to other components. The fixing bolt 18 is a key component that ensures the tight connection between the L-shaped connecting block 17 and other components. The observation window 19 provides operators with a way to directly observe the internal conditions of the insulation box 1. The outer frame 20 plays an important role in protecting the observation window 19. The pressure gauge 21 allows operators to easily read the pressure value during daily operation. The temperature sensor 22 can accurately sense the temperature changes inside the insulation box 1 and convert the temperature signal into an electrical signal to be transmitted to the control system.
[0038] Reference Figure 1 , Figure 3 and Figure 4The top of the perforated partition 7 is connected to a water injection pipe 23, which can inject pure water into the space between the two perforated partitions 7. The outer wall of the water injection pipe 23 penetrates the heat exchange box 3 and is threadedly connected to a cap 24, which can prevent dust, debris and other external objects from entering the water injection pipe 23. The top of the exhaust pipe 15 is connected to a U-shaped vent pipe 25, which can play a certain buffering role. The outer wall of the steam pipe 9 is fixedly connected to a valve 26, which is a key component for controlling the steam flow and on / off. The bottom of the outer wall of the heat insulation box 1 is provided with multiple limiting notches 27, which can allow the trolley to pass through. The rear side of the outer wall of the collection box 209 is rotatably connected to a U-shaped handle 28, which can facilitate the operator to carry and move the collection box 209. The outer wall of the U-shaped handle 28 is fixedly connected to a sponge sleeve 29, which can improve the grip comfort and anti-slip function.
[0039] Specifically, pure water can be added to the space between the two perforated partitions 7 through the water injection pipe 23. The cap 24 can prevent external dust, debris, etc. from entering the water injection pipe 23, thus avoiding pipe blockage. The U-shaped vent pipe 25 can play a certain buffering role. When gas is discharged at high speed from the vent pipe 15, the U-shaped structure can slow down the gas flow rate, reduce the impact of gas on subsequent pipes or equipment, and protect related components from damage. The valve 26 is a key component for controlling the steam flow and switching on and off. The limiting notch 27 allows the trolley to pass through. The U-shaped handle 28 makes it convenient for operators to carry and move the collection box 209. The sponge sleeve 29 can improve grip comfort and anti-slip effect.
[0040] Working principle: Before using the device, the perforated partition 7 and the cylinder 8 work together to form a closed space inside the heat exchange box 3. This space is filled with a large amount of pure water. Then, the external natural gas pipeline is connected through the interface pipe 6, allowing the natural gas to enter the heat-resistant perforated plate 4 through the interface pipe 6 and be sprayed through the natural gas nozzle 5 above, thereby assisting the internal combustion. The flue gas generated during the combustion process passes through the heat exchange box 3, and the flue gas with heat enters the cylinder 8 through the holes of the perforated partition 7, transferring heat to the pure water outside the cylinder 8, causing the water temperature to rise. The water is heated and converted into water vapor. The water vapor then enters the U-shaped pipe 10 through the steam pipe 9 and is sprayed to the inner middle layer area through the steam nozzle 11. At the same time, the blower 12 is activated to introduce outside air through the fixed U-shaped pipe 13 and the air nozzle 14, increasing the oxygen content in the inner bottom layer. The natural gas further assists the internal combustion. The introduction of water vapor helps to reduce the internal carbon monoxide content. By increasing the oxygen content, the combustion process is enhanced, thereby increasing the solid fuel substitution rate and reducing carbon monoxide emissions.
[0041] Furthermore, through the cleaning and collection mechanism 2, after a period of use, a large amount of impurities will accumulate above the perforated partition 7 at the bottom. At this time, the servo motor 201 is started, which drives the bevel gear 202 to rotate, thereby driving the hollow bevel gear 203 and the drive gear 204 to rotate. This series of actions causes the outer rack 205 to move relative to each other, thereby pushing the scraper 206 to remove the impurities above the perforated partition 7. The removed impurities will fall onto the rotating plate 207. When the rotating plate 207 moves above the discharge port 208, the impurities will fall into the collection box 209 due to gravity, thereby realizing the collection and cleaning of impurities and effectively preventing the blockage of the ventilation duct.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
