Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, specifically a desulfurization device for electric furnace exhaust gas in the comprehensive utilization of solid waste. Background Technology

[0002] Electric furnace exhaust gas refers to the high-temperature dust-laden exhaust gas (flue gas) generated during the production process of electric furnaces. Electric furnaces produce a large amount of waste gas during the smelting process. This waste gas contains sulfur dioxide (SO2), which is one of the main components of air pollution and can have a serious impact on the environment and human health. Electric furnace exhaust gas can be purified by a desulfurization device to remove dust and harmful substances.

[0003] According to the desulfurization device for methanol production from tail gas of ferroalloy electric furnace disclosed in application number CN201920242900.1, the device has a main body, and the central axis of the gas bladder inside the main body coincides with the central axis of the storage tank. When the raw material gas inside the conveying pipe passes through the first filter screen to the gas pump, it is conveyed to the gas bladder under the action of the gas pump. The gas bladder is squeezed, which squeezes out the chemical reagent inside the storage tank, making it easier to replenish the first sponge pad below it. However, it is inconvenient to disassemble and replace the adsorbent as needed, which may affect the desulfurization effect.

[0004] Therefore, we propose a desulfurization device for electric furnace tail gas in the comprehensive utilization of solid waste to improve the above-mentioned problems. Utility Model Content

The installation frames 8 are respectively provided with a filter screen 19, an activated carbon filter plate 20 and bamboo charcoal filter particles. A slot 24 is provided at the bottom of the inside of the installation plate 25, a locking block 21 is fixedly connected to the top of the installation frame 8, and an air inlet pipe 6 is fixedly connected to the left side of the filter box 5.

[0026] The card block 21 is set inside the card slot 24 and slides inside the card slot 24. A support plate 3 is fixedly connected between the filter box 5 and the treatment box 2. An air pump 4 is installed on the top of the support plate 3. The output end and input end of the air pump 4 are fixedly connected to fixed pipes respectively. The fixed pipes pass through the interior of the filter box 5 and the treatment box 2 respectively.

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the filter screen 19 and activated carbon filter plate 20 inside the mounting frame 8 can filter and purify the exhaust gas entering the filter box 5, adsorb sulfur dioxide in the exhaust gas, and prevent sulfur dioxide from being directly discharged and affecting the environment. When it is necessary to disassemble and replace the filter screen 19 and activated carbon filter plate 20 inside the mounting frame 8, pull the mounting frame 8. The mounting frame 8 will cause the locking block 21 at the top of the mounting frame 8 to slide inside the locking groove 24, thereby facilitating the disassembly and replacement of the filter screen 19 or activated carbon filter plate 20 inside the mounting frame 8.

[0028] A handle 9 is fixedly connected to the top of the top plate 7. A protective sleeve 22 is sleeved on the outside of the handle 9. Rotary grooves 28 are fixedly connected to both sides of the top of the filter box 5. Rotary blocks 23 are movably connected inside the rotary grooves 28. A limiting plate 27 is fixedly connected to the top of the rotating blocks 23. The bottom of the top plate 7 is embedded in the reserved groove 26. The limiting plate 27 is set on both sides of the top of the top of the top plate 7. The rotating blocks 23 rotate inside the rotary grooves 28.

[0029] Specifically, such as Figure 1, Figure 3 and Figure 5 As shown, when it is necessary to limit and fix the top plate 7, the bottom end of the top plate 7 is placed inside the reserved groove 26. After it is placed, the limiting plate 27 is rotated. The rotating block 23 at the bottom of the limiting plate 27 rotates inside the rotating groove 28, so that the limiting plate 27 can rotate to both sides of the top of the top plate 7 to limit and fix the top plate 7, preventing the top plate 7 from accidentally leaving the filter box 5. The handle 9 at the top of the top plate 7 can easily pull the top plate 7 and the filter box 5.

[0030] A drain pipe 17 is fixedly connected to the bottom right side of the treatment box 2. A valve 18 is provided at the front end of the drain pipe 17. A box body 10 is provided at the top left side of the treatment box 2. A water pump 11 is installed at the top of the box body 10. A connecting pipe 12 is fixedly connected to the output end and the input end of the water pump 11 respectively. A branch pipe 13 is installed on the right side of the connecting pipe 12. Pipes 14 are fixedly connected to the upper and lower ends of the right side of the branch pipe 13. A nozzle 15 is fixedly connected to the bottom end of the pipe 14. A limit frame 16 is installed on the right side inside the treatment box 2. The pipe 14 is located at the top inside the treatment box 2. The limit frame 16 is located on the right side outside the pipe 14.

[0031] Specifically, such as Figure 1 and Figure 3 As shown, the air pump 4 is started, and the air pump 4 draws the gas inside the filter box 5 into the treatment box 2. At the same time as the exhaust gas enters the treatment box 2, the water pump 11 is started. The water pump 11 draws the treatment liquid inside the box 10 into the pipe 14 through the connecting pipe 12 and the branch pipe 13, and then sprays it into the treatment box 2 through the pipe 14 and the nozzle 15, so that the exhaust gas can be further desulfurized.

[0032] Working Principle: In use, the filter screen 19 and activated carbon filter plate 20 inside the mounting frame 8 filter and purify the exhaust gas entering the filter box 5, adsorbing sulfur dioxide. The air pump 4 is activated, drawing gas from inside the filter box 5 into the treatment box 2. Simultaneously, the water pump 11 is activated, drawing the treatment liquid from inside the box 10 into the pipe 14 via the connecting pipe 12 and branch pipe 13. The liquid is then sprayed into the treatment box 2 through the pipe 14 and nozzle 15, further desulfurizing the exhaust gas. When the filter screen 19 and activated carbon filter plate 20 inside the mounting frame 8 need to be disassembled and replaced... Rotate the limiting plate 27 to move it away from the top of the top plate 7. Then, use the handle 9 to take the mounting bracket 8 out of the filter box 5. Pull the mounting bracket 8 again, and the mounting bracket 8 will cause the locking block 21 at the top of the mounting bracket 8 to slide inside the locking groove 24. This makes it easy to disassemble and replace the filter screen 19 or activated carbon filter plate 20 inside the mounting bracket 8. After replacement, put the bottom of the top plate 7 into the reserved groove 26. After it is in place, rotate the limiting plate 27. The rotating block 23 at the bottom of the limiting plate 27 will rotate inside the rotating groove 28. This will allow the limiting plate 27 to rotate to both sides of the top of the top plate 7 to limit and fix the top plate 7, preventing the top plate 7 from accidentally leaving the filter box 5.
