Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment devices, and in particular to a waste gas treatment device using continuous rolling of special-shaped steel. Background Technology

[0002] Continuous rolling of special-shaped steel refers to a process in which steel billets of different shapes and specifications are gradually deformed through a series of roll passes arranged on a continuous rolling line, ultimately rolling them into special-shaped steel products of the required shape and size. These special-shaped steels typically have complex cross-sectional shapes that are not circular or square, such as I-beams, channel steel, H-beams, and angle steel. The continuous rolling process generates waste gas, which requires effective treatment to meet environmental protection requirements.

[0003] In existing technologies, traditional waste gas treatment devices may not be able to fully utilize the packing layer when spraying waste gas, easily resulting in spray dead zones, which affects waste gas treatment efficiency and the service life of the packing. Furthermore, in terms of equipment maintenance, disassembling critical components such as the packing layer can be cumbersome, potentially leading to prolonged equipment downtime and impacting the overall waste gas treatment process. This invention aims to overcome these problems in existing technologies and provide a more efficient and easier-to-maintain waste gas treatment device for continuous rolling mills of special-shaped steel.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Please see Figures 1-5This utility model provides a technical solution: a waste gas treatment device for continuous rolling of special-shaped steel, including a support 1 and a box 2. A liquid inlet pipe 3 is provided on the side of the box 2, a liquid outlet pipe 4 is provided on the lower surface of the box 2, a waste gas inlet pipe 5 is provided on the side of the box 2, a water guide pipe 6 is provided on the side of the box 2, and a hose 7 is fixedly connected to one end of the water guide pipe 6. A packing layer 8 is provided inside the box 2, a gas guide plate 9 is provided inside the box 2, a guide rod 10 is fixedly installed on the inner side of the box 2, an atomizing spray plate 11 is slidably connected to the surface of the guide rod 10, a motor A12 is fixedly installed on the side of the box 2, a threaded rod 13 is rotatably connected inside the box 2, a sliding strip 14 is fixedly connected to the side of the packing layer, an installation plate 15 is fixedly connected to the side of the box 2, a limiting block 16 is slidably connected inside the installation plate 15, a sliding rod 17 is fixedly installed inside the installation plate 15, a tension spring 18 is fixedly installed inside the installation plate 15, a tension spring 19 is fixedly installed inside the box 2, and a top block 20 is fixedly connected to one end of the tension spring 19.

[0026] like Figure 2 and Figure 5 As shown, one end of the hose 7 is fixedly connected to the water inlet of the atomizing spray plate 11, and the output end of the motor A12 is fixedly connected to one end of the threaded rod 13. The threaded rod 13 is threadedly connected to the atomizing spray plate 11.

[0027] The hose 7 allows external liquid to be smoothly delivered to the atomizing spray plate 11. The motor A12 causes the atomizing spray plate 11 to move horizontally, thereby spraying the filler layer 8 evenly, avoiding dead corners during spraying, improving the effective utilization rate of the filler and extending its service life.

[0028] like Figure 1 As shown, the slide bar 14 is slidably connected to the housing 2, and the limiting block 16 is slidably connected to the slide bar 14. Through the sliding cooperation between the limiting block 16 and the slide bar 14, the movement of the packing layer 8 can be limited and stabilized. The limiting block 16 can limit the movement of the packing layer 8.

[0029] like Figure 2 and Figure 5 As shown, the limiting block 16 is slidably connected to the slide rod 17, one end of the tension spring 18 is fixedly connected to the side of the limiting block 16, and the top block 20 is slidably connected to the housing 2. The slide rod 17 ensures that the limiting block 16 moves stably in the horizontal direction, and the tension spring 18 provides the limiting block 16 with the reset and clamping force.

[0030] like Figure 2As shown, a stirring rod 21 is rotatably connected inside the housing 2, and stirring blades 22 are fixedly installed on the surface of the stirring rod 21. A motor B23 is fixedly connected to the side of the housing 2. The motor drives the stirring rod 21 and stirring blades 22 to stir the waste gas, so that the waste gas and the spray liquid are fully mixed. For the neutralization reaction between acidic gas and alkaline spray liquid in the waste gas of special-shaped steel continuous rolling, stirring can greatly increase the contact opportunity of reactants, accelerate the reaction rate, and thus improve the purification effect of the entire waste gas treatment device.

[0031] like Figure 2 As shown, the output end of motor B23 is fixedly connected to one end of stirring rod 21. Motor B23 drives stirring rod 21 to rotate, thereby stirring the liquid and exhaust gas inside the tank 2.

[0032] The operating method and working principle of this device are as follows: During use, alkaline liquid is added to the inside of the tank 2 through the liquid inlet pipe 3. Then, waste gas is discharged into the tank 2 through the waste gas inlet pipe 5. At this time, the motor drives the stirring rod 21 and stirring blades 22 to stir the waste gas, ensuring thorough mixing between the waste gas and the spray liquid. For the neutralization reaction between acidic gases and alkaline spray liquid in the waste gas from the continuous rolling of special-shaped steel, stirring greatly increases the contact opportunities between the reactants, accelerates the reaction rate, and thus improves the purification effect of the entire waste gas treatment device.

[0033] The purified exhaust gas rises through the air guide plate 9 into the packing layer 8. At this point, the motor A12 can be started to rotate the threaded rod 13, thereby moving the atomizing spray plate 11 horizontally. Simultaneously, the atomizing spray plate 11 slides on the surface of the guide rod 10, making its movement more stable. This horizontal movement of the atomizing spray plate 11 ensures uniform spraying of the packing layer 8, avoiding spray dead zones, improving the effective utilization rate of the packing, and extending its service life. When it is necessary to release the packing layer 8, simply pull the limiting block 16, causing it to move along the sliding rod 17 and slide out from inside the sliding strip 14. At this time, the tension spring 19 provides an outward force, causing the top block 20 to push out of the packing layer 8.

[0034] It can unlock the packing layer 8, thereby enabling rapid disassembly of the packing layer 8, which reduces equipment downtime and ensures the continuous and efficient operation of the waste gas treatment device.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
