Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically a steel slag carbonization curing device. Background Technology

[0002] Steel slag is an alkaline industrial solid waste generated during steelmaking. Since steel slag must be cooled before further processing, the existing technology uses a box-type hot quenching method to cool it. This method involves pouring molten steel slag into a slag pot at high temperature and then transporting it to a closed hot quenching slag pit or slag box. Water is then pumped into the slag pot or slag box, and the residual heat of the steel slag is used to generate a large amount of saturated steam. The steel slag is then hot-quenched for a long time in a high-temperature and high-humidity environment. Although this method has the advantage of thorough cooling, the large amount of saturated steam generated by the residual heat of the steel slag also produces a large amount of CO2. The existing technology requires separating CO2 treatment and cooling treatment into two separate processes, which not only occupies space in the work area but also adds unnecessary work steps, making it impractical. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a steel slag carbonization curing device. The technical solution adopted by this utility model to solve its technical problem is as follows: a steel slag carbonization curing device includes a sedimentation tank, with several curing chambers fixedly connected to the top of the sedimentation tank. A steel slag material receiving frame and sealing partition are slidably connected to one side of each curing chamber. The steel slag material receiving frame and sealing partition are used to slide the formed steel slag into the connection between the sedimentation tank and the curing chambers. A water spraying mechanism is fixedly connected to the top of each curing chamber. An exhaust fan unit is installed at one end of the sedimentation tank to remove gas entering the sedimentation tank. A flow-slowing partition component is provided inside the sedimentation tank to separate the flow paths of gas between the various curing chambers.

[0004] Preferably, the steel slag loading rack sealing partition includes a sealing partition movable connecting frame and a sliding guide component. The sealing partition is fixedly connected to the movable connecting frame. Two perforated isolation frames are fixedly connected to one end of the sealing partition located inside the curing chamber. The sliding guide component is fixedly connected to the bottom of the movable connecting frame.

[0005] Preferably, the curing treatment chamber has a central channel, and the curing treatment chamber is interconnected with the sedimentation tank through the central channel.

[0006] Preferably, one end of the water spraying mechanism is fixedly connected to a connecting pipe, which is connected to an external CO gas emission end.

[0007] Preferably, the suction end of the exhaust fan unit extends to the inside of the sedimentation tank, and the output end of the exhaust fan unit is fixedly connected to a discharge end connecting pipe.

[0008] Preferably, the slow-flow separation component includes a tail end connecting plate and an intermediate partition plate, both of which are fixedly connected to the inner wall of the sedimentation tank, and the tail end connecting plate and the intermediate partition plate are staggered.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: After the steel slag is concentrated on the upper end of the perforated isolation frame, the perforated isolation frame is sent into the inner side of the curing treatment chamber through the sliding connecting frame of the sliding conductor. After the movable connecting frame closes the curing treatment chamber, the cooling water source output by the water spray mechanism cools the steel slag at the upper end of the perforated isolation frame. In the spraying state, the connecting pipe can output the solid medium in the residual gas from the exhaust gas discharge end of the heating furnace. As the cooling water sprayed by the water spray mechanism settles synchronously into the sedimentation bottom tank, the water source accumulated in the sedimentation bottom tank after spraying, as well as the restriction of the gas flow path by the tail connecting plate and the intermediate partition plate, ensure that the solid medium in the exhaust gas is fully filtered by water when it enters the bottom position of the sedimentation bottom tank. At the same time, the water-soluble toxic components in the gas are initially purified, achieving the purpose of synchronous operation while reducing the energy consumption of water purification.

[0018] In one optional embodiment of this example, the steel slag loading rack sealing partition 21 includes a sealing partition 21 movable connecting frame 22 and a sliding conductor 23. The sealing partition 21 is fixedly connected to the movable connecting frame 22. Two perforated isolation frames 211 are fixedly connected to one end of the sealing partition 21 located inside the curing chamber 3. The sliding conductor 23 is fixedly connected to the bottom of the movable connecting frame 22.

[0019] In this embodiment, the perforated isolation frame 211 is pushed to slide along the inner side of the curing chamber 3 by the sliding guide 23, thereby realizing the conveying and removal of steel slag. After the sliding guide 23 pushes the perforated isolation frame 211 into the inner side of the curing chamber 3, the sealing partition 21 is located at the opening end of the curing chamber 3, sealing the opening of the curing chamber 3 by the sealing partition 21, keeping the curing chamber 3 closed, and restricting the water spraying mechanism 4 from spraying water. The perforated isolation frame 211 is set to guide the downward flow of water sprayed by the water spraying mechanism 4, and the input end of the water spraying mechanism 4 is connected to an external water source through a hose.

[0020] In one optional embodiment of this example, the curing treatment chamber 3 is provided with a central channel 31, and the curing treatment chamber 3 is interconnected with the sedimentation bottom tank 1 through the central channel 31.

[0021] In this embodiment, the central channel 31 is used to connect the maintenance treatment chamber 3 and the sedimentation tank 1, so that the cooling water output by the water spraying mechanism 4 can flow directly into the inner side of the central channel 31 through the central channel 31. The bottom of the sedimentation tank 1 is equipped with a solenoid valve. After water accumulates inside the sedimentation tank 1, the cooling water that has settled inside the sedimentation tank 1 is discharged to the outside through the solenoid valve.

[0022] In one optional embodiment of this invention, one end of the water spraying mechanism 4 is fixedly connected to a connecting pipe 41, which is connected to an external gas emission end.

[0023] In one optional embodiment of this example, the suction end of the exhaust fan unit 5 extends to the inside of the sedimentation tank 1, and the output end of the exhaust fan unit 5 is fixedly connected to the discharge end connecting pipe 51.

[0024] In this embodiment, 41 is configured to input the residual gas into the interior of 3 through the exhaust pipe of the heating furnace, and after being sprayed by the water spraying mechanism 4, it is deposited inside the sedimentation bottom box 1.

After the movable connecting frame 22 closes the curing treatment chamber 3, the cooling water source output by the water spraying mechanism 4 cools the steel slag at the upper end of the perforated isolation frame 211. In the spraying state, the connecting pipe 41 can output the solid medium in the residual gas from the exhaust gas discharge end of the heating furnace into the chamber 3. As the cooling water sprayed by the water spraying mechanism 4 settles synchronously into the sedimentation bottom tank 1, the water source accumulated inside the sedimentation bottom tank 1 after spraying, as well as the restriction of the gas flow path by the tail connecting plate 61 and the intermediate partition plate 62, ensure that the solid medium in the exhaust gas is fully filtered by water when it enters the bottom position of the sedimentation bottom tank 1. At the same time, the toxic components that are soluble in water in the gas are initially purified, achieving the purpose of synchronous operation while reducing the energy consumption of water purification.
