The cooling process of slag treatment is accompanied by the generation of a large amount of smoke and dust.

[0004] Traditional wet dust removal systems in steel slag processing lines generally suffer from large instantaneous load shocks. Existing technologies mostly use a single main processing tank to directly treat high-concentration flue gas. When the steel slag turning operation suddenly generates dust, the system is prone to a sudden drop in dust removal efficiency due to adjustment lag, and the dust capture efficiency drops sharply. Key parameters such as spray water volume and fan speed need to be manually controlled. The dust generated by slag turning is extremely sudden (usually reaches a peak within 10 to 30 seconds), and manual response cannot match real-time changes.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0026] like Figures 1 to 13 As shown, a wet dust removal device for a steel slag production line includes the following embodiments: Embodiment 1: It includes a processing tank 1, a spray pipe 101 is fixedly connected to the inside of the processing tank 1, and multiple spray heads 102 for spraying are fixedly connected to the outside of the spray pipe 101. The multiple spray heads 102 are arranged in a ring around the center of the processing tank 1. The outside of the processing tank 1 is connected to an air intake pipe 2, and the top of the processing tank 1 is fixedly connected to an exhaust pipe 3. When the flue gas in the production line is discharged into the processing tank 1 through the air intake pipe 2, an external water supply device supplies water to the spray pipe 101, and the water is sprayed through the spray pipe 101 through the external spray heads 102, so that the dust in the flue gas is heavier and falls into the bottom end of the processing tank 1 for treatment, thereby performing wet dust removal on the flue gas. The treated flue gas is discharged through the exhaust pipe 3. It also includes: The annular pipe 7 is fixedly connected to the outside of the treatment tank 1, and multiple smoke exhaust branch pipes 701 are fixedly connected to the outside of the annular pipe 7. The multiple smoke exhaust branch pipes 701 are all extended to the inside of the treatment tank 1; Multiple processing tubes 4 are arranged in an annular manner around the outer side of the air inlet pipe 2. Through grooves are opened on the outer side of the multiple processing tubes 4. The outer side of the air inlet pipe 2 is opened with a communication groove 201 corresponding to the multiple processing tubes 4 one by one. A communication frame 401 is fixedly connected between the multiple processing tubes 4 and the air inlet pipe 2 for communication. A filtering mechanism for flue gas pretreatment is provided inside the processing tube 4; The sealing component is arranged inside the air inlet pipe 2 and is used to seal the connecting groove 201. When the flue gas suddenly increases, the sealing component is pushed to move, and the flue gas is passed through the connecting groove 201 into the multiple processing pipes 4 for pretreatment.

[0027] 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, and 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, and 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 the air outlet frame 704 is connected to the suction end of the external dust collection equipment, and an electromagnet plate 605 is fixedly connected to the outside of the air intake pipe 2.

[0028] During specific implementation, during the production process of the production line, if steel slag overturns and explodes, the automatic system may be delayed by about 10 to 30 seconds due to hydraulic balance, and the amount of water sprayed by the sprinkler head 102 inside the treatment tank 1 cannot be adjusted in time. At this time, a large amount of dust-carrying 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 arranged on the outside of the air intake pipe 2. When the air pressure suddenly increases during the production process, the sealing component inside the air intake pipe 2 is affected by the pressure and the connecting groove 201 opened on the outside of the air intake pipe 2 will be opened. Part of the flue gas enters the treatment pipe 4 through the connecting groove 201 and is pre-treated by the treatment pipe 4, effectively reducing the instantaneous load of the main treatment tank 1 and giving the equipment time to adjust and control. The flue gas that has been pre-treated in the treatment pipe 4 passes through the air intake frame 702 and the connecting pipe 703 and enters the annular pipe 7, so that the exhaust branch pipe 701 outside the annular pipe 7 is discharged inside the treatment tank 1, and wet dust removal is performed inside the treatment tank 1.

[0029] Embodiment 2: The sealing assembly includes a fixing frame 5, which is fixedly connected to the inside of the intake pipe 2, and a sliding disk 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, and both ends of the first spring 504 are fixedly connected to the fixing frame 5 and the sliding disk 502 respectively, and a rotating fan 501 is rotatably connected to one side of the sliding disk 502. A sealing plate 505 is provided on the outside of each of the multiple connecting grooves 201, and the sealing plate 505 is fitted with the outside of the intake pipe 2, and the sealing plates 505 are all slidably connected through the connecting frame 401, and the sealing plate 505 is fixedly connected to the sliding disk 502 through the support rod 503.

[0030] In specific implementation, when the flue gas suddenly increases in pressure, the flue gas will push the rotating fan 501, which will squeeze the sliding disk 502. The sliding disk 502 drives the multiple connecting frames 401 to slide inside through the support rod 503. At this time, the channel between the connecting groove 201 and the processing tube 4 is exposed. At this time, the flue gas will pass through the connecting groove 201 and the connecting frame 401 into the processing tube 4 for pretreatment, achieving the effect of pressure division treatment. In addition, the rotating fan 501 will rotate due to the flue gas, and the rotating fan 501 will stir the flue gas when it rotates. This purely mechanical response mechanism does not require external energy, ensuring the emergency reliability of sudden dust conditions. In this embodiment, the filtering mechanism includes a filter plate 402 that is slidably connected to the inside of the processing tube 4, a connecting plate 403 is fixedly connected to the outside of the filter plate 402, the connecting plate 403 is fixedly connected to the sealing plate 505, and an elastic membrane 404 is provided inside the through groove, the two ends of the elastic membrane 404 are respectively fixedly connected to the connecting plate 403 and one end of the through groove, and the two sides of the elastic membrane 404 are slidably provided inside the through groove for sealing the through groove.

[0031] In specific implementation, when the flue gas passes through the through slot into the inside of the treatment pipe 4, the filter plate 402 in the inside of the treatment pipe 4 pre-filters the dust in the flue gas, thereby relieving the later treatment, and when the connecting plate 403 moves, the elastic film 404 slides, the elastic film 404 seals the communication frame 401, and leakage of the flue gas is avoided.

[0032] The elastic film 404 is made of fluorine rubber material and realizes dynamic sealing in a displacement range under the driving of the connecting plate 403.

[0033] In the third embodiment, the fixed ring 801 is fixedly connected with the filter plate 402, a plurality of telescopic rods 802 and third springs 803 are fixedly connected between the fixed ring 801 and the filter plate 402, the third springs 803 are sleeved outside the telescopic rods 802, a fixed cylinder 804 is fixedly connected in the inside of the fixed ring 801, a rotating rod 806 is arranged in the inside of the fixed cylinder 804, penetrates through one side of the fixed cylinder 804 and is rotationally connected with the fixed cylinder 804, a cleaning frame 807 is fixedly connected to one end of the rotating rod 806 close to the filter plate 402, an impeller 805 is arranged in the inside of the fixed cylinder 804 and is fixedly connected to the outside of the rotating rod 806, a liquid injection assembly is arranged outside the communication frame 401, liquid is discharged into the inside of the fixed cylinder 804 through the liquid injection assembly, and the impeller 805 is driven to rotate.

[0034] One end of the cleaning frame 807 is fixedly connected with a magnetic column 809, a plurality of mounting cylinders 810 are arranged on the side, away from the fixed ring 801, of the filter plate 402, the mounting cylinders 810 are all fixedly connected with the inner wall of the treatment pipe 4, the inside of each mounting cylinder 810 is provided with a magnetic ball 811, a fourth spring 812 is fixedly connected between the magnetic ball 811 and the mounting cylinder 810, and the magnetic ball 811 and the magnetic column 809 are attracted to each other by magnetism.

[0035] In a specific implementation, when the filter plate 402 moves with the connecting plate 403, when the pressure in the flue gas is restored in the later stage, the filter plate 402 is reset. After the connecting plate 403 is reset, a fixing ring 801 is provided on one side of the filter plate 402, and 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 component injects liquid into the fixed cylinder 804, the impeller 805 inside the fixed cylinder 804 is pushed by the liquid to rotate. At this time, the impeller 805 drives the rotating rod 806 to rotate, and the rotating rod 806 drives the cleaning rack 807 fixedly connected at one end to rotate. The brush on one side of the cleaning rack 807 will contact the filter plate 402, thereby cleaning the filter plate 402. 2 Rotational cleaning, and in this solution, a magnetic column 809 is fixedly connected to the outside of the cleaning frame 807, and 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 the magnetic force to compress the third spring 803, so that the brush on the cleaning frame 807 continuously moves back and forth on the filter plate 402, repeatedly cleaning 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 toward the filter plate 402, knocking on the filter plate 402 to knock off the dust, and cooperate with the dust collection device outside the air outlet frame 704 to clean the filtered dust; It can be divided into the following two steps: Reset Trigger Cleaning‌ When the flue gas pressure is restored, 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, and the cleaning frame 807 is driven by the rotating rod 806 to complete a 360° rotation and cleaning.

[0036] Magnetic Enhanced Cleaning The periodic adsorption of the magnetic pillars 809 and the magnetic balls 811 of the cleaning rack 807 produces two effects: Axial vibration: The magnetic ball 811 hits the surface of the filter plate 402, causing the attached dust to fall off; ‌Radial Swing‌: The magnetic force compresses the third spring 803, causing the brush to move back and forth, thereby improving the cleaning coverage.

[0037] It is worth noting that during the resetting process of the filter plate 402, the brush of the cleaning rack 807 will not contact the filter plate 402. Only after the filter plate 402 is completely reset, the brush on the cleaning rack 807 will contact the filter plate 402 through the magnetism of the magnetic column 809, which can prevent dust from falling into the air inlet pipe 2 during the cleaning process. At the same time, after the processing pipe 4 and the air inlet pipe 2 are closed, the smoke will not be sucked out by the dust collection equipment.

[0038] In this embodiment, the liquid injection component includes a liquid suction bag 601, one end of the liquid suction bag 601 is fixedly connected to the connecting frame 401, and the other end of the liquid suction bag 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, and the storage tank 607 and the liquid suction bag 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, and the metal plate 603 is magnetically attracted to the energized electromagnet plate 605. The outside of the liquid suction bag 601 is fixedly connected to a liquid outlet pipe 606, and one end of the liquid outlet pipe 606 is fixedly connected to the fixed cylinder 804. A touch switch is fixedly connected to one side of the connecting frame 401. When the connecting plate 403 contacts the touch switch, the electromagnet plate 605 is de-energized.

[0039] A spraying pipe 813 is fixedly connected to one side of the fixing ring 801 close to the filter plate 402 . The spraying pipe 813 is fixedly connected to the fixing cylinder 804 . A plurality of spraying heads 814 are fixedly connected to the outside of the spraying pipe 813 .

[0040] During specific implementation, when the sealing plate 505 moves, it contacts one side of the metal plate 603, pushing the metal plate 603 to pull the liquid absorption bag 601 to expand and absorb liquid, so that the metal plate 603 slides on the outside of the electromagnet plate 605. When the sealing plate 505 is reset, the metal plate 603 is magnetically adsorbed with the electromagnet plate 605, so that the metal plate 603 remains suspended on the outside of the electromagnet plate 605. At this time, when the connecting plate 403 is completely reset, it contacts the touch switch, and the electromagnet plate 605 is powered off. At this time, the metal plate 603 is under the action of the second spring 602. At this time, the liquid inside the second spring 602 is discharged into the fixed cylinder 804 through the liquid outlet pipe 606. The liquid is diverted to the spray pipe 813 through the fixed cylinder 804, and an atomized liquid curtain is formed through the conical spray head 814, evenly covering the surface of the filter plate 402, dissolving the compacted dust, and spraying the fixed cylinder 804, and cooperating with the cleaning rack 807 for cleaning.

[0044] In the specific implementation, in order to ensure the qualified emission of flue gas, a mounting frame 9 is provided at one end of the exhaust pipe 3 in this solution.
