Description

Technical Field

[0001] The utility model relates to the field of gas purification, in particular to a full-process ultra-clean purification device for converter gas. Background Technique

[0002] Converter gas is a medium-calorific-value gaseous fuel within iron and steel enterprises, mainly generated during the converter steelmaking process. Converter gas usually sprays out from the furnace mouth and entangles a large amount of iron oxide dust. In order to safely and effectively utilize the sprayed converter gas, a full-process ultra-clean purification device is generally used to purify it.

[0003] Generally, when the full-process ultra-clean purification device for converter gas is in operation, the movable hood needs to be placed at the furnace mouth first, and then the gas is absorbed into the vaporization cooling flue through the movable hood. The cooling water is used to cool the gas for the first time. Then, the evaporated cooler uses water mist to cool the cooled flue gas again and achieve rough dust removal. Secondly, the dust collector is used to perform fine dust removal on the flue gas. Then, the flue gas is sent to the washing and cooling tower for further treatment. Finally, the purified gas is sent to the storage system for storage.

[0004] When the converter gas enters the interior of the vaporization cooling flue through the movable hood, a large amount of high-temperature dust carried in the gas is likely to cause blockage at the connection between the movable hood and the vaporization cooling flue. To alleviate this problem, a filter plate is usually installed at the movable hood to reduce the amount of dust entering the vaporization cooling flue, thereby reducing the phenomenon of pipeline blockage. Generally, in order to stably connect the filter plate to the movable hood, welding or multiple bolt connection methods are often used for fixation. However, this fixation method is prone to inconvenience in disassembly when the filter plate needs to be cleaned, thereby affecting the progress of the cleaning work. Therefore, a full-process ultra-clean purification device for converter gas is proposed to solve the above problems. Content of the Utility Model

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, Figure 5 As shown in Figure 5 , a converter gas full-process ultra-clean purification device includes a movable hood body 1 and a limiting component; a vaporization cooling flue 11 is connected to the top of the movable hood body 1; an installation groove 12 is formed in the middle of the movable hood body 1; a filter plate 13 is slidably connected to the middle of the installation groove 12; a bidirectional lead screw 14 is rotatably connected to the middle of the installation groove 12; two groups of sliders 15 are threadedly connected to the middle of the bidirectional lead screw 14; guide columns 16 are fixedly connected to the bottoms of the sliders 15; during operation, first place the filter plate 13 at the installation groove 12 to make it fit against the side wall of the installation groove 12, then hold the end of the bidirectional lead screw 14 and rotate it, so that it rotates in the middle of the movable hood body 1. The rotation of the bidirectional lead screw 14 will drive the sliders 15 to move. When the sliders 15 are moving, their movement trajectories will be affected by the limiting component, and the two groups of sliders 15 will slide in opposite directions respectively in the middle of the bidirectional lead screw 14. The sliding of the sliders 15 will drive the guide columns 16 to move synchronously until the ends of the guide columns 16 abut against both sides of the filter plate 13, then stop rotating the bidirectional lead screw 14. At this time, the operation of fixing the filter plate 13 is completed. When the filter plate 13 needs to be cleaned, rotate the bidirectional lead screw 14 in the reverse direction to make the filter plate 13 fall off from the installation groove 12. Compared with the traditional method of fixing the filter plate 13 by welding or using multiple bolts, this operation only needs to rotate the bidirectional lead screw 14 to complete the installation and disassembly work of the filter plate 13, so as to facilitate the cleaning of the filter plate 13, thereby reducing the situation that the complex disassembly process of the filter plate 13 is likely to affect the cleaning work process and lead to low production efficiency.

[0027] As Figure 3 , Figure 5 , Figure 6As shown in the figure, the limiting component includes an inclined rod 2, a U-shaped plate 21, a rotating shaft 22, a grooved roller 23, a cross bar 24, and a guide rail 25; inclined rods 2 are fixedly connected to both sides of the slider 15; U-shaped plates 21 are fixedly connected to the tops of the inclined rods 2; rotating shafts 22 are rotatably connected to the middles of the U-shaped plates 21; grooved rollers 23 are fixedly connected to the middles of the rotating shafts 22; two groups of cross bars 24 are fixedly connected to both sides of the installation groove 12; guide rails 25 are fixedly connected to the middles of the cross bars 24; the guide rails 25, the cross bars 24, and the grooved rollers 23 are mutually attached; during operation, when the bidirectional lead screw 14 rotates to drive the slider 15 to move, the movement of the slider 15 will drive the inclined rod 2, the U-shaped plate 21, and the grooved roller 23 to move synchronously, and when the grooved roller 23 moves, its movement is restricted by the guide rail 25, thereby changing the movement trajectory of the slider 15, causing the slider 15 to move linearly. At the same time, due to the contact between the grooved roller 23 and the cross bar 24, the movement of the grooved roller 23 will generate friction and interference with the cross bar 24, and then drive the rotating shaft 22 to rotate in the middle of the U-shaped plate 21 under the action of the frictional force, so that the grooved roller 23 rolls along the guide rail 25. This step can change the movement trajectory of the slider 15 through the mutual cooperation of the grooved roller 23 and the guide rail 25, thereby assisting the slider 15 to fix the filter plate 13. Through the rolling action of the grooved roller 23 during movement, the effect of reducing the frictional force between the movable hood body 1 and the cross bar 24 can be achieved, and further the resistance during the movement of the slider 15 can be reduced, making its movement smoother.

[0028] As Figure 3 , Figure 4 , Figure 5 , Figure 7 shown in the figure, two groups of L-shaped supports 3 are fixedly connected to both sides of the installation groove 12; hollow discs 31 are fixedly connected to the ends of the L-shaped supports 3; circular chutes 32 are formed in the middles of the hollow discs 31; multiple groups of balls 33 are rotatably connected to the middles of the circular chutes 32; during operation, the L-shaped supports 3 play a role in supporting the hollow discs 31. When the bidirectional lead screw 14 rotates, it will rotate in the middle of the hollow disc 31, and the bidirectional lead screw 14 will generate friction with the balls 33 during the rotation process. Under the action of the frictional force, it will drive the balls 33 to rotate in the middle of the circular chute 32. This step can support the bidirectional lead screw 14 through the mutual action of the L-shaped supports 3 and the hollow discs 31, thereby providing a support point for the bidirectional lead screw 14 and making it relatively more stable. Through the action of the balls 33, the friction between the bidirectional lead screw 14 and the inner side wall of the hollow disc 31 during rotation can be reduced, and further the rotation process of the bidirectional lead screw 14 can be made smoother.

[0029] As Figure 3 , Figure 4 , Figure 5As shown, L-shaped limit rods 4 are fixedly connected to one side of the hollow disc 31; first limit grooves 41 are provided at both ends of the bidirectional lead screw 14; the ends of the L-shaped limit rods 4 are in mutual contact with the first limit grooves 41; during operation, when the bidirectional lead screw 14 rotates, it will drive the first limit grooves 41 to rotate, and when the first limit grooves 41 rotate, they will rotate along the ends of the L-shaped limit rods 4. Through the mutual cooperation of the L-shaped limit rods 4 and the first limit grooves 41, this step can play a role in restricting the rotation trajectory of the bidirectional lead screw 14, thereby preventing the situation that when the bidirectional lead screw 14 rotates, it is prone to move forward and backward due to uneven force, and further affecting the normal movement of the slider 15.

[0030] As Figure 3 , Figure 4 , Figure 5 As shown, sliding rods 5 are fixedly connected to both sides of the slider 15; two groups of second limit grooves 51 are provided in the middle of the filter plate 13; the bottoms of the sliding rods 5 are in mutual contact with the second limit grooves 51; during operation, when the slider 15 moves, it will drive the sliding rods 5 to move synchronously, and when the sliding rods 5 move, their bottoms will slide along the middle of the second limit grooves 51. At the same time, through the mutual cooperation of the sliding rods 5 and the second limit grooves 51, the function of restricting the movement trajectory of the slider 15 can be achieved. Through the mutual action of the sliding rods 5 and the second limit grooves 51, this step can assist the limit component to restrict the slider 15, thereby stabilizing the movement trajectory of the slider 15 again and strengthening its function of moving in a straight line.

[0031] As Figure 3 , Figure 4 As shown, two groups of limit plates 6 are fixedly connected to the middle of the slider 15; during operation, when the slider 15 moves to a certain position, it will come into contact with the limit plates 6, and the limit plates 6 can play a role in preventing the slider 15 from continuing to move. Through the action of the limit plates 6, this step can restrict the movement trajectory of the slider 15, thereby reducing the movement length of the slider 15 in the middle of the bidirectional lead screw 14, and further reducing the friction length between the slider 15 and the bidirectional lead screw 14, so as to prevent the situation that the wear of the slider 15 is easily aggravated due to too long movement friction.

[0032] As Figure 3 , Figure 4 , Figure 5 As shown, extrusion plates 7 are fixedly connected to the ends of the guide posts 16; during operation, when the slider 15 drives the guide posts 16 to fix the filter plate 13, the guide posts 16 will drive the extrusion plates 7 to move synchronously, and the extrusion plates 7 will contact the filter plate 13 first and fix the filter plate 13 before the guide posts 16. Through the action of the extrusion plates 7, this step can increase the contact area between the guide posts 16 and the filter plate 13, and further increase the fixing effect of the guide posts 16 on the filter plate 13, making the fixing of the filter plate 13 more firm.

[0033] Working principle: During operation, first place the filter plate 13 at the installation groove 12 so that it fits against the side wall of the installation groove 12. Then, hold the end of the bidirectional lead screw 14 and rotate it, causing it to rotate in the middle of the movable hood body 1. The rotation of the bidirectional lead screw 14 will drive the slider 15 to move. When the slider 15 moves, its movement trajectory will be affected by the limit component, and the two sliders 15 will slide in opposite directions at the middle part of the bidirectional lead screw 14. The sliding of the slider 15 will drive the guide post 16 to move synchronously until the end of the guide post 16 abuts against both sides of the filter plate 13, then stop rotating the bidirectional lead screw 14. At this time, the operation of fixing the filter plate 13 is completed. When the filter plate 13 needs to be cleaned, rotate the bidirectional lead screw 14 in the reverse direction to make the filter plate 13 fall off from the installation groove 12. Compared with the traditional method of fixing the filter plate 13 by welding or using multiple bolts, this operation only requires rotating the bidirectional lead screw 14 to complete the installation and disassembly of the filter plate 13, which can facilitate the cleaning of the filter plate 13, thereby reducing the situation where the complex disassembly process of the filter plate 13 easily affects the cleaning process and leads to low production efficiency. During operation, when rotating the bidirectional lead screw 14 to drive the slider 15 to move, the movement of the slider 15 will drive the inclined rod 2, U-shaped plate 21, and groove roller 23 to move synchronously. When the groove roller 23 moves, its movement trajectory is restricted by the guide rail 25, causing the slider 15 to move in a straight line. At the same time, due to the contact between the groove roller 23 and the cross bar 24, the movement of the groove roller 23 will generate friction and interference with the cross bar 24. Then, under the action of the frictional force, the rotating shaft 22 will rotate in the middle of the U-shaped plate 21, causing the groove roller 23 to roll along the guide rail 25. This step can change the movement trajectory of the slider 15 through the mutual cooperation of the groove roller 23 and the guide rail 25, thereby assisting the slider 15 to fix the filter plate 13. Through the rolling action of the groove roller 23 during movement, the frictional force between the movable hood body 1 and the cross bar 24 can be reduced, thereby reducing the resistance during the movement of the slider 15 and making its movement smoother. During operation, the L-shaped support 3 plays a role in supporting the hollow disc 31. When the bidirectional lead screw 14 rotates, it will rotate in the middle of the hollow disc 31, and during the rotation process of the bidirectional lead screw 14, it will generate friction with the ball 33. Under the action of the frictional force, the ball 33 will rotate in the middle of the circular chute 32. This step can support the bidirectional lead screw 14 through the mutual action of the L-shaped support 3 and the hollow disc 31, thereby providing a support point for the bidirectional lead screw 14 to make it relatively more stable. Through the action of the ball 33, the friction between the bidirectional lead screw 14 and the inner side wall of the hollow disc 31 during rotation can be reduced, making the rotation process of the bidirectional lead screw 14 smoother. During operation, when the bidirectional lead screw 14 rotates, it will drive the first limit groove 41 to rotate, and when the first limit groove 41 rotates, it will rotate along the end of the L-shaped limit rod 4. This step is through the mutual cooperation of the L-shaped limit rod 4 and the first limit groove 41,It can play a role in restricting the rotation trajectory of the bidirectional lead screw 14, thereby preventing the situation that when the bidirectional lead screw 14 rotates, it is prone to move back and forth due to uneven force, which will affect the normal movement of the slider 15. During operation, when the slider 15 moves, it will drive the slide bar 5 to move synchronously. When the slide bar 5 moves, its bottom will slide along the middle of the second limit groove 51. At the same time, through the mutual cooperation of the slide bar 5 and the second limit groove 51, it can play a role in restricting the movement trajectory of the slider 15. Through the interaction of the slide bar 5 and the second limit groove 51 in this step, it can assist the limit component to restrict the slider 15, thereby stabilizing the movement trajectory of the slider 15 again and strengthening its function of moving in a straight line. During operation, when the slider 15 moves to a certain position, it will come into contact with the limit plate 6, and the limit plate 6 can play a role in preventing the slider 15 from continuing to move. Through the action of the limit plate 6 in this step, it can restrict the movement trajectory of the slider 15, thereby reducing the movement length of the slider 15 in the middle of the bidirectional lead screw 14, and further reducing the friction length between the slider 15 and the bidirectional lead screw 14, so as to prevent the situation that the wear of the slider 15 is easily aggravated due to excessive movement friction. During operation, when the slider 15 drives the guide post 16 to fix the filter plate 13, the guide post 16 will drive the pressing plate 7 to move synchronously, and the pressing plate 7 will contact the filter plate 13 first and fix the filter plate 13 before the guide post 16. Through the action of the pressing plate 7 in this step, it can increase the contact area between the guide post 16 and the filter plate 13, and further increase the fixing effect of the guide post 16 on the filter plate 13, making the filter plate 13 fixed more firmly.
