Description

Technical Field

[0001] The utility model belongs to the technical field of blast furnace smelting, in particular to a dust suppression device used for reverse transportation of blast furnace materials. Background Art

[0002] During normal blast furnace production, each production link maintains smooth and stable operation, ensuring the continuity and efficiency of the production process. However, when faced with unexpected equipment failures or necessary equipment maintenance, measures to discharge and transport materials are necessary to ensure the safety and stability of the entire production line. Through reasonable planning and efficient execution of these operations, equipment can be repaired promptly, the failure can be prevented from escalating, the impact on production schedule can be minimized, and a solid foundation for the subsequent stable operation of the blast furnace can be laid.

[0003] When materials are discharged and transported, measures to reduce smoke and dust are necessary. We typically deploy mist cannons to suppress dust generation, but the area where the blast furnace's operating belt is located is confined, making it difficult for them to access the space. This not only limits their operational flexibility but also significantly reduces their dust removal effectiveness. Furthermore, the belt's relatively high discharge height makes it difficult for the cannons, even if they can barely enter the operating area, to accurately spray the atomized water vapor at the discharge point. Since the atomized water vapor can't reach the source of the dust, the dust removal effect is suboptimal. Summary of the Invention

[0004] To address the challenges of existing technologies, this utility model provides a dust suppression device for blast furnace material transfer. This device, unrestricted by the confines of a narrow workspace, ensures that atomized water vapor is accurately sprayed onto the unloading point of the blast furnace's operating belt. While maintaining efficient dust removal, it successfully overcomes the operational difficulties of conventional fog cannons in confined areas.

[0005] The utility model is realized as follows: a dust suppression device for blast furnace material reverse transportation comprises a water supply pipeline mounted on a belt conveyor support through a support frame, the water supply pipeline being connected to an external water source, a control valve being provided on the water supply pipeline, an atomizing generating pipe connected to the water supply pipe being provided at a material unloading position of the belt conveyor, and an atomizing nozzle being provided on the atomizing generating pipe;

[0006] The atomizing generating tube includes an outer ring tube and an inner ring tube arranged concentrically, and the outer ring tube and the inner ring tube are connected through a connecting section. There are multiple atomizing nozzles, and the multiple atomizing nozzles are evenly distributed on the outer ring tube and the inner ring tube.

[0007] Furthermore, the atomizing nozzles of the outer ring tube are staggered with those of the inner ring tube. This staggered distribution of atomizing nozzles can form a denser spray network, ensuring that the water mist can cover a wider area. It also makes the spray of water mist more uniform, avoiding the situation where the water mist is too thick or too thin in some areas. It also improves the redundancy of the system. Even if some nozzles fail or become clogged, the other nozzles can still continue to work, ensuring the continuous and stable operation of the spray system and reducing downtime and maintenance costs caused by failures.

[0008] Furthermore, the atomizing nozzle of the outer ring tube is tilted 10-40 degrees toward the outside of the outer ring tube, so that the water mist can be diffused outward at a certain angle, thereby expanding the coverage of the spray.

[0009] Furthermore, the atomizing nozzles of the inner ring tube are tilted 10 to 40 degrees inwards. This ensures that the water mist is sprayed at a more precise angle to the area surrounded by the inner ring tube, especially the core area where dust is more concentrated. Working in conjunction with the atomizing nozzles of the outer ring tube, they form a denser spray network, enhancing the capture and sedimentation capabilities of dust.

[0010] Furthermore, 20 atomizing nozzles are evenly distributed on the outer annular tube, and 12 atomizing nozzles are evenly distributed on the inner annular tube.

[0011] Furthermore, the atomized water droplet particles of the atomizing nozzle are 200 to 300 μm.

[0012] The advantages and technical effects of the present invention are as follows: Due to the adoption of the above-mentioned technical solution, it is not limited by the narrow working space, and ensures that the atomized water vapor is accurately sprayed to the unloading point of the blast furnace running belt. While maintaining the efficient dust removal effect, it successfully overcomes the operational difficulties of traditional fog cannon vehicles in space-constrained areas. The concentrically arranged outer ring tube and inner ring tube make the structure of the entire atomization generating tube more compact, saving space, and is particularly suitable for space-constrained working environments; it can significantly improve the spraying efficiency, ensuring a wider and more accurate coverage of various locations where dust is generated, not only optimizing the distribution pattern of the spray water, but also through the synergistic effect of the inner and outer ring tubes, achieving comprehensive encirclement and efficient suppression of the dust source. The water mist sprayed by the outer ring tube can form a broad barrier, effectively intercepting and settling suspended particles in the air, while the inner ring tube performs targeted spraying on areas where dust is more concentrated, further enhancing the dust removal effect.

[0018] like Figure 1 and Figure 2 As shown, the present application provides a dust suppression device for the unloading of blast furnace materials, including a water supply pipe 3 mounted on a belt conveyor bracket 2 through a support frame 5, the water supply pipe 3 is connected to an external water source, a control valve 4 is provided on the water supply pipe 3, and an atomizing pipe 6 connected to the water supply pipe 3 is provided at the unloading position of the belt conveyor 1, and an atomizing nozzle 7 is provided on the atomizing pipe 6. Specifically, the atomized water droplet particles of the atomizing nozzle 7 are 200 to 300 μm.

[0019] The atomizing generating tube 6 includes an outer ring tube 6-1 and an inner ring tube 6-2 arranged concentrically, and the outer ring tube 6-1 and the inner ring tube 6-2 are connected by a connecting section 6-3. There are multiple atomizing nozzles 7, and the multiple atomizing nozzles 7 are evenly distributed on the outer ring tube 6-1 and the inner ring tube 6-2.

[0020] Furthermore, the atomizing nozzles 7 of the outer ring tube 6-1 are staggered with the atomizing nozzles 7 of the inner ring tube 6-2. The staggered distribution of the atomizing nozzles 7 can form a denser spray network, ensuring that the water mist can cover a wider area; and make the spray of the water mist more uniform, avoiding the situation where the water mist is too thick or too thin in some areas; and improve the redundancy of the system. Even if some nozzles fail or become clogged, the other nozzles can still continue to operate, ensuring the continuous and stable operation of the spray system and reducing the downtime and maintenance costs caused by failures.

[0021] Furthermore, the atomizing nozzle 7 of the outer ring tube 6-1 is tilted 10 to 40 degrees toward the outside of the outer ring tube 6-1. This allows the water mist to diffuse outward at a certain angle, thereby expanding the coverage of the spray. The atomizing nozzle 7 of the inner ring tube 6-2 is tilted 10 to 40 degrees toward the inside of the inner ring tube 6-2. This ensures that the water mist is sprayed at a more precise angle to the area surrounded by the inner ring tube 6-2, especially to the core area where dust is more concentrated. It works in conjunction with the atomizing nozzle 7 of the outer ring tube 6-1 to form a denser spray network, thereby enhancing the ability to capture and settle dust.

[0022] Furthermore, 20 atomizing nozzles 7 are evenly distributed on the outer annular tube 6 - 1 , and 12 atomizing nozzles 7 are evenly distributed on the inner annular tube 6 - 2 .

[0023] Due to the adoption of the above technical solution, it is not limited by the narrow working space, ensuring that the atomized water vapor is accurately sprayed to the unloading point of the blast furnace running belt. While maintaining the efficient dust removal effect, it successfully overcomes the operational difficulties of traditional fog cannon vehicles in space-constrained areas. The concentrically arranged outer ring tube 6-1 and inner ring tube 6-2 make the structure of the entire atomization generating tube 6 more compact, saving space, and is particularly suitable for space-constrained working environments; it can significantly improve the spraying efficiency, ensuring a wider and more accurate coverage of various locations where dust is generated. It not only optimizes the distribution pattern of the spray water, but also achieves comprehensive encirclement and efficient suppression of the dust source through the synergistic effect of the inner and outer ring tubes. The water mist sprayed by the outer ring tube 6-1 can form a wide barrier, effectively intercepting and settling suspended particles in the air, while the inner ring tube 6-2 performs targeted spraying on areas where dust is more concentrated, further enhancing the dust removal effect.
