Description

Technical Field

[0001] The invention belongs to the technical field of boiler dust removal, in particular to a high-efficiency metallurgical boiler dust removal device. Background Art

[0002] Metallurgical boilers are industrial furnaces that perform heat treatment on various materials or workpieces during the metallurgical production process. Metallurgical boilers produce a large amount of flue gas during the combustion process. If these flue gases are directly discharged into the air, they will pollute the environment. Therefore, it is necessary to remove the dust from the flue gas generated by the metallurgical boiler before discharging it to reduce the impact of the flue gas on the environment.

[0003] The patent with announcement number CN216566326U discloses a steam boiler dust removal device, including a dust removal box, wherein the interior of the dust removal box is provided with a dust removal chamber and a purification chamber from left to right in sequence, wherein a circulating pump is arranged inside the dust removal chamber, wherein a liquid guide tube is fixedly connected to the output end of the circulating pump, wherein the end of the liquid guide tube away from the circulating pump is fixedly connected to a nozzle rack, wherein a spray head is fixedly connected to the outer surface of the nozzle rack, wherein a dust removal filter is plugged into the interior of the dust removal chamber, wherein an activated carbon adsorption plate and a sterilization plate are plugged into the interior of the purification chamber from left to right in sequence. In the steam boiler dust removal device, when gas enters the interior of the dust removal box and the circulating pump is started, water inside the dust removal chamber can be drawn out and sprayed out through the spray head, which can reduce dust in the gas, and dust will fall on the dust removal filter with the water sprayed from the spray head and be adsorbed by the dust removal filter, and dust can be cleaned by simply cleaning the dust removal filter, and the aqueous solution can be reused and recycled.

[0004] However, the above technical solution still has the following deficiencies in practical application: Although the flue gas can be extracted through the air intake pipe to enter the dust removal box and perform a series of dust removal operations, usually, the flue gas of the metallurgical boiler is discharged from the exhaust pipe of the metallurgical boiler, and in order to ensure the extraction effect of the flue gas, the air intake pipe and the flue gas exhaust pipe need to be connected. In the above technical solution, when it is necessary to remove dust from the flue gas emitted by different metallurgical boilers, the specifications of the flue gas exhaust pipes of different metallurgical boilers may be different, while the specifications of the air intake pipe are fixed. Therefore, when the air intake pipe and the flue gas exhaust pipe are connected, a gap may be generated between the two due to mismatched specifications, resulting in part of the flue gas being unable to smoothly enter the dust removal box through the air intake pipe, but being discharged into the air, which still pollutes the environment and affects the dust removal efficiency.

[0034] Specifically, when the existing boiler dust removal device is in use, although the flue gas can be extracted through the air intake pipe to enter the dust removal box 2 and perform a series of dust removal operations, usually, the flue gas of the metallurgical boiler is discharged from the exhaust pipe of the metallurgical boiler, and in order to ensure the extraction effect of the flue gas, the air intake pipe and the flue gas exhaust pipe need to be connected. In the prior art, when it is necessary to remove dust from the flue gas discharged by different metallurgical boilers, the specifications of the flue gas exhaust pipes of different metallurgical boilers may be different, while the specifications of the air intake pipe are fixed. Therefore, when the air intake pipe and the flue gas exhaust pipe are connected, a gap may be generated between the two due to mismatched specifications, resulting in part of the flue gas being unable to smoothly enter the dust removal box through the air intake pipe, but being discharged into the air, thereby still causing pollution to the environment and affecting the dust removal efficiency. Therefore, in order to solve the above problems, when the present embodiment is in use, the universal wheel 8 can be used to move the entire device and move it to the vicinity of the metallurgical boiler. Then, according to the height of the smoke exhaust pipe of the metallurgical boiler, the motor 9 is used to drive the threaded rod 10 to rotate, so that the lifting plate 11 slides up and down in the slide groove of the slide groove frame 7 to adjust the height of the hard pipe 12, and the universal wheel 8 is used to move the base 1 until the hard pipe 12 is aligned with the smoke exhaust pipe, and the axes of the two coincide, and the smoke exhaust pipe extends into the inner cavity of the sealing gasket 24. Then, according to the distance between the sealing gasket 24 and the outer wall of the smoke exhaust pipe at this time, the motor 5 30 is used to drive the threaded rod 3 29 to rotate, so that the adjusting ring 21 moves horizontally, and the connecting rod 23 Under the action of , the multiple adjustment rods 28 are simultaneously moved radially on the displacement ring 22, so that the sealing gasket 24 is close to the smoke exhaust pipe until the inner wall of the sealing gasket 24 fits with the outer wall of the smoke exhaust pipe, and the smoke exhaust pipe can be wrapped with the sealing gasket 24. At this time, the exhaust fan 4 is used to extract the smoke, and the sealing gasket 24 can intercept the smoke discharged from the smoke exhaust pipe, so that the smoke can smoothly enter the dust removal box 2, thereby avoiding the situation that when the smoke enters the hard pipe 12 through the smoke exhaust pipe, due to the mismatch of the specifications of the hard pipe 12 and the smoke exhaust pipe, a gap is generated between the two, and part of the smoke cannot smoothly enter the dust removal box 2, which still causes pollution to the environment and affects the dust removal efficiency; Although the gasket 24 can be used to wrap the smoke exhaust pipe in the above manner, after the gasket 24 has been used for a period of time, a certain amount of dust will adhere to its inner surface. When the dust accumulates on the inner surface of the gasket 24, it will not only affect the fit between the gasket 24 and the smoke exhaust pipe, thereby reducing the sealing effect, but also affect the elasticity of the gasket 24, which is not conducive to subsequent repeated use. Therefore, workers are required to clean the inner surface of the gasket 24 regularly. However, since the dust is on the inner surface of the gasket 24, it is not easy for workers to observe the location of the dust on the inner surface of the gasket 24, and it is not easy for workers to reach into the inner cavity of the gasket 24 with their hands, thereby affecting the cleaning effect. Therefore, in order to avoid this problem, when the dust adhering to the inner surface of the gasket 24 is needed, the gasket 24 is cleaned regularly. When cleaning the dust, the sealing gasket 24 can be stretched by the adjusting rod 28 first, so that the sealing gasket 24 can be expanded, and then the motor 17 is used to drive the threaded rod 16 to rotate, so that the displacement ring 22 moves horizontally and approaches the fixed plate 15, and one side of the sealing gasket 24 will be supported by the support ring 18, and the adjusting ring 21 and the displacement ring 22 can pass through the support ring 18 without conflict. When the displacement ring 22 moves to the fixed plate 15, the inner surface of the sealing gasket 24 is turned to the outside. At this time, the worker can clean the inner surface of the sealing gasket 24 turned to the outside, thereby avoiding the situation that the worker is not easy to observe the dust position on the inner surface of the sealing gasket 24, and the hand is not easy to reach into the inner cavity of the sealing gasket 24, thereby affecting the cleaning effect of the inner surface of the sealing gasket 24; Furthermore, since the sealing pad 24 is elastic, some dust may be hidden in the tiny gaps or depressions of the sealing pad 24, making it difficult for workers to find it, thereby affecting the cleaning effect. Therefore, in order to avoid this situation, when the sealing pad 24 is turned over, the sealing pad 24 will cover the push plate 19. When the worker determines the area that needs to be cleaned, the motor 3 25 is used to drive the gear 26 to rotate, so that the rotating ring 20 rotates, and the position of the push plate 19 is adjusted to make the push plate 19 align with the area of ​​the sealing pad 24 that needs to be cleaned, and then the electric push rod 31 is used to drive the push plate 19 to move, so that the push plate 19 pushes the sealing pad 24, so that the area of ​​the sealing pad 24 that needs to be cleaned forms a bulge, so that the gaps and depressions that were originally difficult to observe are enlarged, and the dust is easier to show, which is convenient for the worker to clean the sealing pad 24, and avoids the situation that some dust is hidden in the tiny gaps or depressions of the sealing pad 24, making it difficult for the workers to find it, thereby affecting the cleaning effect.

[0035] Working principle: the whole device can be moved by the universal wheel 8 and moved to the vicinity of the metallurgical boiler. Then, according to the height of the smoke exhaust pipe of the metallurgical boiler, the motor 9 is used to drive the threaded rod 10 to rotate, so that the lifting plate 11 slides up and down in the slide groove of the slide groove frame 7 to adjust the height of the hard pipe 12, and the universal wheel 8 is used to move the base 1 until the hard pipe 12 is aligned with the smoke exhaust pipe, and the axes of the two coincide, and the smoke exhaust pipe extends into the inner cavity of the sealing gasket 24. Then, according to the distance between the sealing gasket 24 and the outer wall of the smoke exhaust pipe at this time, the motor 5 30 is used to drive the threaded rod 3 29 to rotate, so that the adjusting ring 21 moves horizontally, and the connecting rod 23 can be adjusted. Under the action, the multiple adjustment rods 28 are simultaneously moved radially on the displacement ring 22, so that the sealing gasket 24 is close to the smoke exhaust pipe until the inner wall of the sealing gasket 24 fits with the outer wall of the smoke exhaust pipe, and the smoke exhaust pipe can be wrapped with the sealing gasket 24. At this time, the exhaust fan 4 is used to extract the smoke, and the sealing gasket 24 can intercept the smoke discharged from the smoke exhaust pipe, so that the smoke can smoothly enter the dust removal box 2, and the water in the inner cavity of the dust removal box 2 is pumped out by the pump body 14, so that the water flows through the water inlet pipe 40 and the water outlet pipe 3 and is sprayed from the spray hood 36, which can play a dust reduction role on the dust in the smoke, so that the dust in the smoke can be removed, and the dust will be blown away by the water. The water flows on the filter screen 37, and the water flows back to the lower side of the inner cavity of the dust removal box 2 through the filter screen 37. The spray water can be recycled, and the smoke after the spray dust reduction will be discharged through the discharge pipe 33, and the smoke will pass through the activated carbon adsorption plate 34 and the sterilization plate 35 on the inner wall of the discharge pipe 33. The activated carbon adsorption plate 34 and the sterilization plate 35 can further adsorb and sterilize the smoke, which can ensure that the smoke contains less harmful substances. In addition, when it is necessary to replace the spray water, the water flow can be discharged through the drain pipe 39; when it is necessary to clean the dust adhering to the inner surface of the sealing gasket 24, the sealing gasket 24 can be stretched by the adjusting rod 28 to make the sealing gasket 24 To expand, and then use the motor 2 17 to drive the threaded rod 2 16 to rotate, so that the displacement ring 22 moves horizontally and approaches the fixed plate 15, and one side of the sealing gasket 24 will be supported by the support ring 18, and the adjustment ring 21 and the displacement ring 22 can pass through the support ring 18 without conflict. When the displacement ring 22 moves to the fixed plate 15, the inner surface of the sealing gasket 24 is turned to the outside. At this time, the worker can clean the inner surface of the sealing gasket 24 turned to the outside, thereby avoiding the situation that the worker is not easy to observe the dust position on the inner surface of the sealing gasket 24, and the hand is not easy to reach into the inner cavity of the sealing gasket 24, thereby affecting the cleaning effect of the inner surface of the sealing gasket 24; Furthermore, since the sealing pad 24 is elastic, some dust may be hidden in the tiny gaps or depressions of the sealing pad 24, making it difficult for workers to find it, thereby affecting the cleaning effect. Therefore, in order to avoid this situation, when the sealing pad 24 is turned over, the sealing pad 24 will cover the push plate 19. When the worker determines the area that needs to be cleaned, the motor 3 25 is used to drive the gear 26 to rotate, so that the rotating ring 20 rotates, and the position of the push plate 19 is adjusted to make the push plate 19 align with the area of ​​the sealing pad 24 that needs to be cleaned, and then the electric push rod 31 is used to drive the push plate 19 to move, so that the push plate 19 pushes the sealing pad 24, so that the area of ​​the sealing pad 24 that needs to be cleaned forms a bulge, so that the gaps and depressions that were originally difficult to observe are enlarged, and the dust is easier to show, which is convenient for the worker to clean the sealing pad 24, and avoids the situation that some dust is hidden in the tiny gaps or depressions of the sealing pad 24, making it difficult for the workers to find it, thereby affecting the cleaning effect.
