Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a waste gas treatment device for iron and steel smelting with dust removal function. Background Technology

[0002] The steel smelting process generates a large amount of waste gas containing harmful substances such as dust, sulfides, and nitrogen oxides. If this waste gas is discharged directly without effective treatment, it will not only cause serious air pollution, leading to environmental problems such as smog and acid rain, but also pose a significant threat to the health of nearby residents. Therefore, the research and application of waste gas treatment equipment for steel smelting is of paramount importance.

[0003] According to announcement number CN 113019043 A, a waste gas treatment device with dust removal function includes a water tank, a bottom box welded to the surface of the water tank, a dust removal mechanism installed inside the bottom box, a vertical plate welded inside the water tank, a crushing mechanism installed on the rear wall of the water tank, and a spraying mechanism installed on the bottom wall of the water tank to the right of the vertical plate. The right side of the vertical plate is fixedly connected to the inner wall of the water tank through a horizontal plate.

[0004] This rotating shaft uses a water source to perform preliminary dust removal on the exhaust gas, reducing the dust content. Then, an air pump pumps the exhaust gas into the bottom chamber and dust collection pipe, allowing it to be filtered again through a filter screen, filter plate, and filter box after water adsorption. This further reduces particulate matter in the exhaust gas, achieving the goal of dust removal and meeting environmental protection requirements. However, this device cannot reduce the high-temperature exhaust gas to a suitable treatment temperature, thus affecting the subsequent dissolution and absorption of harmful components in the exhaust gas.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1.

At the same time, the first servo motor drives the fan blade assembly on the first rotating shaft to rotate through the transmission of the first sprocket, chain and second sprocket, generating airflow to force-cool the waste gas in the exhaust pipe. The heat dissipation holes on the first fixed frame also help dissipate heat. The dual cooling method effectively reduces the temperature of the waste gas, creating more suitable treatment conditions for the subsequent dissolution mechanism, improving the dissolution efficiency of harmful components in the waste gas, and avoiding the impact of high temperature on the dissolution effect and equipment stability.

[0017] 2. This steel smelting waste gas treatment equipment with dust removal function, through the set dissolution component, the first servo motor drives the stirring shaft and spiral blades to rotate, stirring the solution in the second tank, so that the waste gas can fully contact and mix with the solution after being discharged from the gas outlet of the gas outlet pipe, which accelerates the dissolution rate of soluble harmful components in the waste gas, improves the dissolution effect, the liquid injection pipe facilitates the replenishment of solution, and the exhaust pipe timely discharges the gas generated during the dissolution process, ensuring the smooth progress of the dissolution process and improving the purification level of the waste gas.

[0018] 3. This steel smelting waste gas treatment equipment with dust removal function, through the set dust removal mechanism, the cover is fixed to the top of the first box by bolts for easy disassembly and maintenance. The second servo motor drives the second rotating shaft to rotate, and through the meshing transmission of the first bevel gear and the second bevel gear, it drives the third rotating shaft to rotate. In turn, the first gear and the second gear cooperate with each other to drive the limit frame to rotate. The limit frame cooperates with the limit ring on the surface of the dust collector to limit the dust collector, ensuring that the dust collector continuously and efficiently filters dust particles in the waste gas, greatly improving the cleanliness of the waste gas entering the subsequent treatment process, and reducing the impact and wear of dust on other treatment components.

[0019] 4. This steel smelting waste gas treatment equipment with dust removal function, through a set filtration mechanism, pumps the solution after dissolving the waste gas in the second chamber into the third chamber, where it is filtered through a filter plate. A hydraulic cylinder drives a rack, which meshes with the third gear to drive the fifth rotating shaft to rotate, causing block L to abut against the filter plate for limiting and fixing, ensuring the stability of the filtration process. The filtered solution flows back to the second chamber through the groove at the bottom of the inner wall of the third and second chambers, realizing the recycling of the solution, reducing the treatment cost, and ensuring the cleanliness and effectiveness of the solution in the dissolving mechanism, maintaining the long-term stable operation of the equipment.

[0032] See Figure 12-14 Furthermore, based on Example 1, a filtration mechanism 7 was obtained.

[0033] Furthermore, the filtration mechanism 7 includes a third housing 71, which is fixedly connected to the top right side of the second housing 511.

[0036] In actual operation, when this device is used, the exhaust gas generated by steel smelting first enters the first chamber 2 through the air inlet pipe 3. Inside the first chamber 2, the dust removal mechanism 6 starts to function, the second servo motor 67 starts, driving the second rotating shaft 68 to rotate. The first bevel gear 69 on the second rotating shaft 68 meshes with the second bevel gear 612 on the third rotating shaft 611, causing the third rotating shaft 611 to rotate. The first gear 613 and the second gear 615 on the third rotating shaft 611 cooperate with each other to drive the four third rotating shafts 611 to rotate, thereby driving the limiting frame 616 to rotate. The limiting frame 616 cooperates with the limiting ring 66 on the surface of the dust removal cylinder 65 to limit the dust removal cylinder 65, ensuring that the dust removal cylinder 65 continuously and efficiently filters dust particles in the exhaust gas, thus achieving preliminary dust removal. After dust removal, the exhaust gas flows out of the first chamber 2 through the exhaust pipe 4 and enters the cooling component 52. At this time, the first servo motor 513 not only drives the stirring shaft 514 to stir the solution, but also drives the second sprocket 529 to rotate through the chain 5211 on the first sprocket 528 on its output shaft. This causes the fan blade assembly 527 on the first rotating shaft 526 to rotate. The airflow generated by the fan blade assembly 527 works in conjunction with the heat dissipation fins 523 on the surface of the exhaust pipe 4 and the heat dissipation holes 522 on the first fixed frame 521 to perform double cooling on the exhaust gas in the exhaust pipe 4, thereby reducing the exhaust gas temperature and creating suitable conditions for subsequent dissolution treatment. After cooling, the exhaust gas enters the dissolution component 51 of the second chamber 511 through the exhaust port 516 on the exhaust pipe 4. The first servo motor 513 drives the stirring shaft 514 and the spiral blade 515 to rotate, stirring the solution in the second chamber 511, so that the exhaust gas and the solution can fully contact and mix, accelerating the dissolution rate of soluble harmful components in the exhaust gas. The liquid injection pipe 517 can replenish the solution, and the exhaust pipe 518 can promptly discharge the gas generated during the dissolution process, ensuring that the dissolution process proceeds smoothly and achieving the purification treatment of the exhaust gas. After the waste gas is dissolved, the solution is pumped into the filter mechanism 7 of the third chamber 71 through the inlet pipe 74 via the pump body 73. The hydraulic cylinder 79 drives the rack 711 to move, and the rack 711 meshes with the third gear 712, which drives the fifth rotating shaft 77 to rotate, so that the L block 78 abuts against the filter plate 72 for limiting and fixing, ensuring the stability of the filtration process. After the solution is filtered through the filter plate 72, it flows back to the second chamber 511 through the groove at the bottom of the inner wall of the third chamber 71 and the second chamber 511, realizing the recycling of the solution and continuously providing a clean and effective solution for the dissolution of waste gas.
