Description

A wet dust removal device for steel slag production line Technical Field

[0001] This invention relates to the field of wet dust removal technology, and in particular to a wet dust removal device for a steel slag production line. Background Technology

[0002] The purpose of steel slag treatment is to cool, pulverize, and magnetically separate the high-temperature liquid steel slag produced in converters or electric furnaces during the steelmaking process. The cooling process of steel slag treatment is accompanied by the generation of a large amount of flue gas and dust.

[0003] Referring to patent application CN222342377U, a wet dust removal device for a steel slag production line is disclosed. The device includes a dust collector body, a dust-laden air shell on the top of one side of the body, and a clean air discharge port on the top of the other side. Inside the dust-laden air shell is a spray chamber with several atomizing nozzles installed on the top of its inner wall. A water supply pipe is located on the top of the dust-laden air shell. A dust removal chamber is located on one side of the dust collector body, and a dehydration chamber is located on the other side. An S-bend is located on one side of the inner wall of the dust removal chamber, and a rotating shaft is rotatably connected to the bottom of one side of the inner wall. An impeller is installed in the middle of the rotating shaft. Three layers of arc-shaped baffles are located on one side of the inner wall of the dehydration chamber, and a baffle plate is located above the three arc-shaped baffles on the inner wall of the dehydration chamber. This wet dust removal device for a steel slag production line treats the dust-laden gas in multiple ways, resulting in high efficiency and good dust removal effect.

[0004] Traditional wet dust removal systems in steel slag processing lines generally suffer from large instantaneous load impacts. Existing technologies mostly use a single main treatment tank to directly treat high-concentration flue gas. When dust suddenly rises during steel slag turning operations, the system's adjustment lag can easily lead to a sharp drop in dust removal efficiency and dust collection efficiency. Key parameters such as spray water volume and fan speed need to be manually adjusted. However, dust from turning operations is extremely sudden (usually reaching its peak within 10 to 30 seconds), and manual response cannot keep up with real-time changes.

[0005] Therefore, it is necessary to provide a wet dust removal device for steel slag production lines to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a wet dust removal device for steel slag production lines to solve the problems of the prior art mentioned in the background section.

[0015] As a further aspect of the present invention: a magnetic column is fixedly connected to one end of the cleaning frame, and multiple mounting cylinders are provided on the side of the filter plate away from the fixing ring. The multiple mounting cylinders are all fixedly connected to the inner wall of the processing tube, and a magnetic ball is provided inside the mounting cylinder. A fourth spring is fixedly connected between the magnetic ball and the mounting cylinder, and the magnetic ball and the magnetic column are attracted by magnetism.

[0016] As a further embodiment of the present invention: the liquid injection assembly includes a liquid suction bladder, one end of which is fixedly connected to a connecting frame, and the other end of which is fixedly connected to a metal plate. A second spring is fixedly connected between the metal plate and the connecting frame. A storage tank is fixedly connected to the outside of the air inlet pipe. The storage tank and the liquid suction bladder are connected through a branch pipe. When the sealing plate slides out of the connecting frame, it pushes the metal plate to move. The metal plate is magnetically attracted to the electromagnet plate after it is energized. A liquid outlet pipe is fixedly connected to the outside of the liquid suction bladder. One end of the liquid outlet pipe is fixedly connected to a fixed cylinder. A tactile switch is fixedly connected to one side of the connecting frame.

[0019] As a further aspect of the present invention: the inner side of the fixed disk is provided with multiple arc-shaped grooves, the inside of the fixed disk is rotatably connected to a cutting disk, the outer side of the cutting disk is provided with multiple cutting grooves, each of the multiple cutting grooves is provided with a dust sensor, the inside of the cutting disk is fixedly connected to a transmission rod, one end of the transmission rod is fixedly connected to an electromagnet sheet, the electromagnet sheet is magnetically attracted to the rotating disk after being energized, and the other end of the electromagnet sheet passes through the connecting disk and the mounting frame in sequence and is rotatably connected to the connecting disk and the mounting frame.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By connecting the flue gas through the trough, some of the flue gas enters the treatment pipe and undergoes pretreatment, which effectively reduces the instantaneous load on the main treatment tank and gives the equipment time to adjust and control. The flue gas that has been pretreated in the treatment pipe passes through the inlet frame and the connecting pipe and enters the annular pipe, so that the exhaust branch pipe on the outside of the annular pipe is discharged inside the treatment tank, where wet dust removal is performed.

[0022] 2. The channel between the connecting groove and the treatment pipe is exposed. At this time, the flue gas will enter the treatment pipe through the connecting frame via the connecting groove for pretreatment, achieving the effect of pressure division treatment. The rotating fan will rotate in response to the flue gas, and the rotating fan will agitate the flue gas movement. This purely mechanical response mechanism does not require external energy, ensuring the emergency reliability of sudden dust storm conditions.

[0023] 3. A magnetic column is fixedly connected to the outside of the cleaning frame. The magnetic column and the magnetic ball on one side of the filter plate are magnetically attracted. When the magnetic column rotates with the cleaning frame and moves to the vicinity of the magnetic ball, the cleaning frame is subjected to magnetic force, which compresses the third spring. This causes the brush on the cleaning frame to move back and forth on the filter plate repeatedly to clean the filter plate. At the same time, when the magnetic ball and the magnetic column are magnetically attracted, the magnetic ball will move towards the filter plate and knock the dust off. In addition, the dust collection device on the outside of the air outlet frame will clean the filtered dust.

[0024] 4. The intercepted flue gas is detected by a dust sensor. After the flue gas is detected, it passes through the rotating return pipe and is then introduced into the annular pipe for secondary treatment, forming a "detection-feedback" closed-loop system to ensure that the emission concentration meets the national standard limit. When the detected flue gas fails to meet the standard, the electromagnet is energized, and the electromagnet magnetically attracts the rotating disk, causing the rotating disk to rotate and align with the return pipe. The gas inside the exhaust pipe is then passed through the annular pipe for secondary treatment. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0041] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0042] As shown in Figures 1 to 13, a wet dust removal device for a steel slag production line includes the following embodiments:

[0043] Example 1: Includes a treatment tank 1, with a spray pipe 101 fixedly connected inside. Multiple spray heads 102 are fixedly connected to the outside of the spray pipe 101, arranged in a ring around the center of the treatment tank 1. An air inlet pipe 2 connects to the outside of the treatment tank 1, and an exhaust pipe 3 connects to the top of the treatment tank 1. When flue gas from the production line enters the treatment tank 1 through the air inlet pipe 2, an external water supply device supplies water to the spray pipe 101. Water is then sprayed through the spray pipe 101 and the outer spray heads 102, causing dust in the flue gas to be heavier and fall into the bottom of the treatment tank 1 for treatment, thus performing wet dust removal. The treated flue gas is discharged through the exhaust pipe 3. The system also includes:

[0044] The annular pipe 7 is fixedly connected to the outside of the treatment tank 1, and multiple exhaust branch pipes 701 are fixedly connected to the outside of the annular pipe 7. All the exhaust branch pipes 701 extend into the inside of the treatment tank 1.

[0045] Multiple processing pipes 4 are arranged in a ring around the outside of the air inlet pipe 2. Each processing pipe 4 has a through groove on its outer side. The air inlet pipe 2 has a connecting groove 201 that corresponds to each processing pipe 4 on its outer side. Each processing pipe 4 and the air inlet pipe 2 are fixedly connected by a connecting frame 401 for communication. The processing pipe 4 is equipped with a filter mechanism for flue gas pretreatment.

[0046] A sealing assembly is installed inside the air inlet pipe 2 to seal the connecting groove 201. When the flue gas suddenly increases, it pushes the sealing assembly to move, allowing the flue gas to pass through the connecting groove 201 into multiple treatment pipes 4 for pretreatment.

[0047] An air intake frame 702 is fixedly connected to the outside of the air intake pipe 2. A connecting pipe 703 is fixedly connected between the air intake frame 702 and the annular pipe 7. A one-way valve is installed on the outside of the connecting pipe 703. The air intake frame 702 is fixedly connected to one end of multiple processing pipes 4. An air outlet frame 704 is fixedly connected to the other end of the air intake pipe 2. The air outlet frame 704 is fixedly connected to multiple processing pipes 4 and is connected to the suction end of an external vacuum cleaner. An electromagnet plate 605 is fixedly connected to the outside of the air intake pipe 2.

[0048] In practical implementation, during the production process, if there is an explosive dust release due to the overturning of steel slag, the automatic system may be delayed by about 10 to 30 seconds due to hydraulic balance. The water volume sprayed by the spray head 102 inside the treatment tank 1 cannot be adjusted in time. At this time, a large amount of dust-laden flue gas will escape, causing the flue gas treated by the treatment tank 1 to fail to meet the standards in a short time. Therefore, in this solution, multiple treatment pipes 4 are set on the outside of the air inlet pipe 2. When the air pressure suddenly increases during the production process, the sealing component inside the air inlet pipe 2 will be pressured and will open the connecting groove 201 on the outside of the air inlet pipe 2. Through the connecting groove 201, some flue gas enters the treatment pipe 4 and is pre-treated through the treatment pipe 4, which effectively reduces the instantaneous load of the main treatment tank 1 and gives the equipment time to adjust and control. The flue gas that has been pre-treated in the treatment pipe 4 enters the annular pipe 7 through the air inlet frame 702 and the connecting pipe 703, so that the exhaust branch pipe 701 on the outside of the annular pipe 7 is discharged inside the treatment tank 1, and wet dust removal is performed inside the treatment tank 1.

[0049] Example 2: The sealing assembly includes a fixing frame 5, which is fixedly connected to the inside of the air intake pipe 2. A sliding plate 502 is slidably connected to the outside of the fixing frame 5. A first spring 504 is sleeved on the outside of the fixing frame 5. The two ends of the first spring 504 are fixedly connected to the fixing frame 5 and the sliding plate 502 respectively. A rotating fan 501 is rotatably connected to one side of the sliding plate 502. A sealing plate 505 is provided on the outside of the multiple connecting slots 201. The sealing plate 505 is in contact with the outside of the air intake pipe 2. The sealing plate 505 is slidably connected through the connecting frame 401. The sealing plate 505 is fixedly connected to the sliding plate 502 through the support rod 503.

[0050] In practical implementation, when the flue gas suddenly increases in pressure, it pushes the rotating fan 501, which in turn compresses the sliding disc 502. The sliding disc 502, via the support rod 503, causes multiple connecting frames 401 to slide internally, exposing the channel between the connecting groove 201 and the treatment pipe 4. The flue gas then passes through the connecting groove 201 and the connecting frame 401 into the treatment pipe 4 for pretreatment, achieving a pressure-splitting effect. Furthermore, the rotating fan 501 rotates in response to the flue gas, agitating its movement. This purely mechanical response mechanism requires no external energy, ensuring emergency reliability in sudden dust storm situations.

[0051] In this embodiment, the filtration mechanism includes a filter plate 402 slidably connected to the inside of the processing tube 4, a connecting plate 403 fixedly connected to the outside of the filter plate 402, the connecting plate 403 being fixedly connected to the sealing plate 505, and an elastic membrane 404 being provided inside the through groove. The two ends of the elastic membrane 404 are fixedly connected to the connecting plate 403 and one end of the through groove, respectively, while the two sides of the elastic membrane 404 are slidably disposed inside the through groove for sealing the through groove.

[0052] In practice, when the flue gas enters the treatment pipe 4 through the channel, the filter plate 402 inside the treatment pipe 4 pre-filters the dust in the flue gas, thereby alleviating the need for subsequent treatment. When the connecting plate 403 moves, the elastic membrane 404 slides, and the elastic membrane 404 seals the connecting frame 401 to prevent flue gas leakage.

[0053] The elastic membrane 404 is made of fluororubber and achieves dynamic sealing within the displacement range under the action of the connecting plate 403.

[0054] Example 3: A fixed ring 801 is fixedly connected to the filter plate 402 by multiple telescopic rods 802 and a third spring 803, with the third spring 803 sleeved on the outside of the telescopic rods 802. A fixed cylinder 804 is fixedly connected inside the fixed ring 801. A rotating rod 806 is provided inside the fixed cylinder 804. The rotating rod 806 passes through one side of the fixed cylinder 804 and is rotatably connected to the fixed cylinder 804. A cleaning frame 807 is fixedly connected to the end of the rotating rod 806 near the filter plate 402. An impeller 805 is provided inside the fixed cylinder 804. The impeller 805 is fixedly connected to the outside of the rotating rod 806. A liquid injection assembly is provided on the outside of the connecting frame 401. Liquid is discharged into the fixed cylinder 804 through the liquid injection assembly, driving the impeller 805 to rotate.

[0055] A magnetic column 809 is fixedly connected to one end of the cleaning frame 807. Multiple mounting cylinders 810 are provided on the side of the filter plate 402 away from the fixing ring 801. The multiple mounting cylinders 810 are fixedly connected to the inner wall of the treatment tube 4. A magnetic ball 811 is provided inside the mounting cylinder 810. A fourth spring 812 is fixedly connected between the magnetic ball 811 and the mounting cylinder 810. The magnetic ball 811 and the magnetic column 809 are attracted by magnetism.

[0056] In specific implementation, when the filter plate 402 moves together with the connecting plate 403, and the pressure in the flue gas recovers later, the filter plate 402 resets. After the connecting plate 403 resets, a fixing ring 801 is provided on one side of the filter plate 402. A third spring 803 and a telescopic rod 802 are fixedly connected between the fixing ring 801 and the filter plate 402. When the liquid injection assembly injects liquid into the fixed cylinder 804, the impeller 805 inside the fixed cylinder 804 will rotate due to the push of the liquid. At this time, the impeller 805 drives the rotating rod 806 to rotate, and the rotating rod 806 drives the cleaning frame 807 fixedly connected at one end to rotate. The brush on one side of the cleaning frame 807 will contact the filter plate 402, thereby cleaning the filter plate 402. 2. Rotation cleaning: In this solution, a magnetic column 809 is fixedly connected to the outside of the cleaning frame 807. The magnetic column 809 is magnetically attracted to the magnetic ball 811 on one side of the filter plate 402. When the magnetic column 809 rotates with the cleaning frame 807 to the vicinity of the magnetic ball 811, the cleaning frame 807 is subjected to magnetic force, which compresses the third spring 803, causing the brush on the cleaning frame 807 to move back and forth on the filter plate 402 repeatedly to clean the filter plate 402. At the same time, when the magnetic ball 811 is magnetically attracted to the magnetic column 809, the magnetic ball 811 will magnetically move towards the filter plate 402, knocking the dust off the filter plate 402. In conjunction with the dust collection device on the outside of the air outlet frame 704, the filtered dust is cleaned.

[0057] It can be divided into the following two steps:

[0058] Reset trigger cleaning

[0059] When the flue gas pressure recovers, the connecting plate 403 drives the filter plate 402 to reset, and the fixing ring 801 maintains structural stability through the third spring 803 and the telescopic rod 802. After the liquid injection assembly is started, the liquid drives the impeller 805 to rotate, which drives the cleaning frame 807 to complete 360° rotation cleaning through the rotating rod 806.

[0060] Magnetic Enhanced Cleaning

[0061] The periodic adsorption of the magnetic pillars 809 and magnetic balls 811 on the cleaning rack 807 produces two effects:

[0062] Axial vibration: The magnetic ball 811 impacts the surface of the filter plate 402, causing the attached dust to fall off;

[0063] Radial oscillation: The magnetic force compresses the third spring 803, causing the brush to reciprocate and improve cleaning coverage.

[0064] It is worth noting that during the reset process of filter plate 402, the brush on cleaning frame 807 will not come into contact with filter plate 402. Only after filter plate 402 is fully reset will the brush on cleaning frame 807 come into contact with filter plate 402 through the magnetism of magnetic column 809. This can prevent dust from falling into the air inlet pipe 2 during the cleaning process. At the same time, after the treatment pipe 4 is sealed with the air inlet pipe 2, the flue gas will not be sucked out by the dust collection equipment.

[0065] In this embodiment, the liquid injection assembly includes a liquid suction bladder 601. One end of the liquid suction bladder 601 is fixedly connected to the connecting frame 401, and the other end of the liquid suction bladder 601 is fixedly connected to a metal plate 603. A second spring 602 is fixedly connected between the metal plate 603 and the connecting frame 401. A storage tank 607 is fixedly connected to the outside of the air inlet pipe 2. The storage tank 607 and the liquid suction bladder 601 are connected through a branch pipe. When the sealing plate 505 slides out of the connecting frame 401, it pushes the metal plate 603 to move. The metal plate 603 is magnetically attracted to the energized electromagnet plate 605. An outlet pipe 606 is fixedly connected to the outside of the liquid suction bladder 601. One end of the outlet pipe 606 is fixedly connected to the fixed cylinder 804. A tactile switch is fixedly connected to one side of the connecting frame 401. When the connecting plate 403 contacts the tactile switch, the electromagnet plate 605 is de-energized.

[0066] A spray pipe 813 is fixedly connected to the side of the fixing ring 801 near the filter plate 402. The spray pipe 813 is fixedly connected to the fixing cylinder 804. Multiple spray heads 814 are fixedly connected to the outside of the spray pipe 813.

[0067] In practice, when the sealing plate 505 moves, it contacts one side of the metal plate 603, pushing the metal plate 603 to pull the liquid-absorbing bag 601 to expand and absorb liquid, causing the metal plate 603 to slide on the outside of the electromagnet plate 605. When the sealing plate 505 resets, the metal plate 603 and the electromagnet plate 605 are magnetically attracted, keeping the metal plate 603 suspended on the outside of the electromagnet plate 605. At this time, when the connecting plate 403 is fully reset, it contacts the tactile switch, and the electromagnet plate 605 is de-energized. At this time, the metal plate 603 is activated by the second spring 602. The liquid inside the second spring 602 is discharged into the fixed cylinder 804 through the liquid outlet pipe 606. The liquid is diverted through the fixed cylinder 804 to the spray pipe 813, forming an atomized liquid curtain through the conical spray head 814, which evenly covers the surface of the filter plate 402, dissolving the plated dust and thus spraying and washing the fixed cylinder 804, in conjunction with the cleaning frame 807 for cleaning.

[0068] The liquid can be an alkaline solution, adjusted according to actual needs.

[0069] Example 4: One end of the exhaust pipe 3 is fixedly connected to the mounting frame 9. The mounting frame 9 is provided with a rotating disk 901, a fixed disk 902 and a connecting disk 903 on one side. The fixed disk 902 and the connecting disk 903 are both fixedly connected to the mounting frame 9. The outside of the connecting disk 903 is fixedly connected to the exhaust pipe 904 and the return pipe 905. The return pipe 905 is fixedly connected to the annular pipe 7.

[0070] Multiple arc-shaped grooves 9021 are provided on the inner side of the fixed plate 902. A cutting plate 906 is rotatably connected inside the fixed plate 902. Multiple cutting slots 9061 are provided on the outer side of the cutting plate 906. Dust sensors are installed inside each of the multiple cutting slots 9061. A transmission rod 908 is fixedly connected inside the cutting plate 906. An electromagnet 907 is fixedly connected to one end of the transmission rod 908. When the electromagnet 907 is energized, it is magnetically attracted to the rotating plate 901. The other end of the electromagnet 907 passes through the connecting plate 903 and the mounting frame 9 in sequence and is rotatably connected to the connecting plate 903 and the mounting frame 9.

[0071] In specific implementation, to ensure the compliance of flue gas emissions, this solution includes an installation frame 9 at one end of the exhaust pipe 3. After the flue gas is treated, it is discharged through the rotating disk 901, the fixed disk 902, and the exhaust pipe 904 on one side of the connecting disk 903. During the discharge process, a drive motor is installed on one side of the installation frame 9. The output shaft of the drive motor is fixedly connected to the transmission rod 908. The transmission rod 908 drives the intercepting disk 906 to rotate inside the fixed disk 902, continuously intercepting a portion of the flue gas. A dust sensor is installed inside the intercepting groove 9061. The dust sensor detects the intercepted flue gas. After the flue gas is detected, it passes through the rotating return pipe 905 and is then introduced into the annular pipe 7 for secondary treatment, forming a "detection-feedback" closed-loop system to ensure that the emission concentration meets the national standard limit. When the detected flue gas fails to meet the standard, the electromagnet 907 is energized, and the electromagnet 907 is magnetically attracted to the rotating disk 901, causing the rotating disk 901 to rotate and align with the return pipe 905. This allows the gas inside the exhaust pipe 3 to undergo secondary treatment inside the annular pipe 7.
