Description

Technical Field

[0001] The present invention belongs to the technical field of generator sets, and specifically relates to a generator set that utilizes the thermal energy of the off-gas from a submerged arc furnace. Background Art

[0002] Submerged arc furnaces are widely used in industries such as metallurgy and chemical engineering. However, during the production process, they generate a large amount of off-gas, which not only contains combustible gases such as carbon monoxide and hydrogen, but also carries a large amount of thermal energy.

[0003] However, when the existing submerged arc furnace off-gas is used to drive a generator set to operate, the water in the boiler body is often heated by the submerged arc furnace off-gas to generate steam, thereby driving the conversion component to operate, and the conversion component drives the generator to operate. However, when heating the water in the boiler, it is often necessary to heat the pipeline first and then heat the water in the boiler. This will cause the dust to adhere to the outer wall of the pipeline when the submerged arc furnace off-gas passes through the pipeline. After the outer wall of the pipeline is heated for a long time, it is easy to scale on the outer wall of the pipeline, thereby affecting the subsequent heating of the water in the pipeline.

The third cleaning ring 2044 and the fourth cleaning ring 2045 are symmetrical to each other. The third cleaning ring 2044 and the fourth cleaning ring 2045 are respectively sleeved on the outside of the water pipe 102. The driving component is used to drive the first cleaning ring 2041 and the second cleaning ring 2042 to move. The driving component can also be used to drive the two circular turntables 303 to rotate.First, when the off-gas of the submerged arc furnace is used to transmit gas, it can drive the driving component to operate at this time. When the driving component operates, it can drive the first guiding sleeve 2033 and the second guiding sleeve 2034 to move relatively in the vertical direction. When the first guiding sleeve 2033 and the second guiding sleeve 2034 move relative to each other, they can drive the first cleaning ring 2041 and the second cleaning ring 2042 to move, and when they move, they can scrape the dust on the outer wall of the water pipe 102. When the first cleaning ring 2041 and the second cleaning ring 2042 move, they can also drive the third cleaning ring 2044 and the fourth cleaning ring 2045 to move horizontally through the movable rod 2043, so as to clean the dust on the pipe wall of the water pipe 102 in the horizontal direction. At the same time, when the first guiding sleeve 2033 and the second guiding sleeve 2034 move, they can also drive the circular turntable 303 to rotate, and the knocking plate 3034 can be driven to knock on the water pipe 102, so that the dust can fall faster during the cleaning process, and there will be no situation where some dust adheres to the outer wall of the water pipe 102 and cannot fall off.

[0037] As Figures 2 to 3 and Figure 5 shown, in the specific implementation manner, the driving component includes a turning plate 201. The turning plate 201 is rotatably connected to the bottom of the boiler body 101. A first connecting plate 2025 is arranged above the turning plate 201, and the other end of the first connecting plate 2025 is connected to a rotating mechanism. In this setting, the installation position and components of the driving component are determined.

[0038] As Figures 2 to 7 shown, further, the rotating mechanism includes a rotating cylinder 202. A first bearing 2021 is arranged at the bottom of the rotating cylinder 202. An inclined surface 2022 is formed on one side wall of the rotating cylinder 202. An arc-shaped chute 2023 is formed on the inclined surface 2022. A moving slider 2024 is slidably installed in the inner cavity of the arc-shaped chute 2023. One end of the moving slider 2024 is fixedly connected to a first connecting plate 2025. In this setting, the installation position and components of the rotating mechanism are determined.

[0039] As Figures 2 to 7As shown in the figure, further, a rotating rod 203 is fixedly installed above the rotating cylinder 202. A first guiding chute 2031 and a second guiding chute 2032 are provided above the rotating rod 203. The first guiding chute 2031 and the second guiding chute 2032 are symmetrical to each other. Guide sliders are slidably installed in the inner cavities of the first guiding chute 2031 and the second guiding chute 2032. One ends of the two guide sliders are respectively fixedly connected with a first guiding sleeve 2033 and a second guiding sleeve 2034. The first guiding sleeve 2033 and the second guiding sleeve 2034 are symmetrical to each other. A first sliding mechanism is arranged on one side wall of the first guiding sleeve 2033 and the second guiding sleeve 2034. In this setting, it is ensured that when the rotating rod 203 rotates, the first guiding sleeve 2033 and the second guiding sleeve 2034 can be driven by the first guiding chute 2031 and the second guiding chute 2032 respectively to perform vertical relative movement with the assistance of the first chute 2035 and the first slider 2036.

[0040] As Figure 3 shown in the figure, further, the first sliding mechanism includes a first chute 2035. The first chute 2035 is opened on the inner wall of the boiler body 101. Two symmetrical first sliders 2036 are slidably installed in the inner cavity of the first chute 2035. One ends of the two first sliders 2036 are respectively fixedly connected with the first guiding sleeve 2033 and the second guiding sleeve 2034. In this setting, the installation position and components of the first sliding mechanism are determined.

[0041] As Figure 2 and Figures 3 to 7 shown in the figure, further, second connecting plates 204 are respectively fixedly connected to one side wall of the first guiding sleeve 2033 and the second guiding sleeve 2034. The two second connecting plates 204 are symmetrical to each other. One ends of the two second connecting plates 204 are respectively fixedly connected to the first cleaning ring 2041 and the second cleaning ring 2042. In this setting, it is ensured that when the first guiding sleeve 2033 and the second guiding sleeve 2034 perform vertical relative movement, the first cleaning ring 2041 and the second cleaning ring 2042 can be driven to perform relative movement through the second connecting plates 204 respectively.

[0042] Embodiment 2:

[0043] Based on the above embodiment, the difference from this embodiment is that as Figure 2 and Figures 3 to 7As shown in the figure, a power generation unit utilizing the waste heat of the exhaust gas of a submerged arc furnace is provided. On the opposite side walls of two second connecting plates 204, connecting rods 3012 are respectively arranged. The two connecting rods 3012 are symmetrical to each other. On one side wall of each of the two connecting rods 3012, a first moving plate 3011 is fixedly installed. The two first moving plates 3011 are symmetrical to each other. An irregular guide rod 301 passes through the two first moving plates 3011 movably. The two ends of the irregular guide rod 301 are respectively fixedly connected to the opposite side walls inside the boiler body 101. Two symmetrical guide rods 3013 pass through the two first moving plates 3011 movably. The two ends of the two guide rods 3013 are respectively fixedly connected to the upper and lower side walls of the boiler body 101. In this setting, when the first guide sleeve 2033 and the second guide sleeve 2034 move vertically relative to each other, they can respectively drive the connecting rods 3012 to move vertically relative to each other. When the connecting rods 3012 move relative to each other, they can drive the first moving plates 3011 to move horizontally relative to each other. When the two first moving plates 3011 move relative to each other, they can move back and forth with the assistance of the irregular guide rod 3013.

[0044] As Figure 2 and Figures 3 to 7 shown, in the specific implementation manner, two symmetrical positioning plates 3014 are respectively fixedly connected in the middle of the two guide rods 3013. On the opposite side walls of the two positioning plates 3014, return springs 3015 are fixedly installed. The other end of each return spring 3015 is respectively fixedly connected to the first moving plate 3011. In this setting, it is ensured that the first moving plate 3011 can be reset.

[0045] As Figure 2 and Figures 3 to 7 shown, further, two symmetrical push rods 3016 are fixedly installed on one side wall of the two first moving plates 3011. A moving mechanism is arranged at the end of each push rod 3016 away from the first moving plate 3011. In this setting, it is ensured that when the first moving plate 3011 moves forward, it can push the second moving plate 302 to move horizontally with the assistance of the slide rail 3021 through the push rod 3016.

[0046] As Figure 2 and Figures 3 to 7As shown in the figure, further, the moving mechanism includes a second moving plate 302. A push rod 3016 is attached to one side wall of the second moving plate 302. Above the second moving plate 302, there are two symmetrically arranged slide rails 3021, and the two slide rails 3021 are arranged on the inner wall of the boiler body 101. One side wall of the second moving plate 302 is also slidably connected to a driving rod 3033. In this setting, it is ensured that when the second moving plate 302 moves horizontally, it will be able to push the driving rod 3033 to drive the circular turntable 303 to rotate with the assistance of the rotating rod 3031. When the circular turntable 303 rotates, it can drive the knocking plate 3034 to knock on the water pipe 102, so that the dust will fall faster during the cleaning process, and there will be no situation where some dust adheres to the outer wall of the water pipe 102 and cannot fall off.

[0047] The implementation principle of a power generation unit using the waste heat of the submerged arc furnace tail gas of the present invention is as follows:

[0048] First, the staff filters the tail gas discharged from the submerged arc furnace through the filtering component, and then connects it to the boiler body 101 through the intake pipe 1013. Therefore, the filtered tail gas of the submerged arc furnace can enter the boiler body 101 (where the tail gas of the submerged arc furnace can first blow the turning plate 201 to open with the assistance of the rotating component. When the turning plate 201 opens, the tail gas of the submerged arc furnace can enter the boiler body 101).

[0049] At the same time, when the turning plate 201 opens, the turning plate 201 can press the first connecting plate 2025 to move horizontally, so that the rotating cylinder 202 can be driven to rotate with the assistance of the arc-shaped chute 2023 and the moving slider 2024. When the rotating cylinder 202 rotates, it can drive the rotating rod 203 to rotate.

[0050] When the rotating rod 203 rotates, it can drive the first guide sleeve 2033 and the second guide sleeve 2034 to move vertically relative to each other through the first guide chute 2031 and the second guide chute 2032 respectively, with the assistance of the first chute 2035 and the first slider 2036. When the first guide sleeve 2033 and the second guide sleeve 2034 move vertically relative to each other, they will be able to drive the first cleaning ring 2041 and the second cleaning ring 2042 to move relative to each other through the second connecting plate 204 respectively. When the first cleaning ring 2041 and the second cleaning ring 2042 move, they will be able to scrape the dust on the outer wall of the water pipe 102. When the first cleaning ring 2041 and the second cleaning ring 2042 move, they will also be able to drive the third cleaning ring 2044 and the fourth cleaning ring 2045 to move horizontally through the movable rod 2043. Therefore, the third cleaning ring 2044 and the fourth cleaning ring 2045 can clean the horizontal pipe wall of the water pipe 102, so that the cleaned dust can fall onto the inclined plate and be discharged from the blanking port 1015 through the inclined plate;

[0051] At the same time, when the first guide sleeve 2033 and the second guide sleeve 2034 move vertically relative to each other, they can also drive the connecting rods 3012 to move vertically relative to each other respectively. When the connecting rods 3012 move relative to each other, they will be able to drive the first moving plate 3011 to move horizontally relative to each other. When the two first moving plates 3011 move relative to each other, they will be able to move back and forth under the assistance of the special-shaped guide rod 3013. When the first moving plate 3011 moves forward, it will be able to push the second moving plate 302 to move horizontally with the assistance of the slide rail 3021 through the push rod 3016. When the second moving plate 302 moves horizontally, it will be able to push the driving rod 3033 to drive the circular turntable 303 to rotate with the assistance of the rotating rod 3031. When the circular turntable 303 rotates, it can drive the knocking plate 3034 to knock on the water pipe 102, so that the dust can fall faster during the cleaning process, and there will be no situation where some dust adheres to the outer wall of the water pipe 102 and cannot fall (because the turning plate 201 is affected by the exhaust gas of the submerged arc furnace, so it moves irregularly during operation. However, whether it is affected by large or small exhaust gas, the turning plate 201 can turn at this time, so the above steps can be completed).
