[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Reference Figures 1-10 A steel slag carbonization reaction device includes a reactor 100, a heating unit 400 inside the reactor 100, a baffle 205 for placing carbon slag inside the reactor 100, a water storage pan 307 at the bottom of the baffle 205, and a pressure relief valve 108 at the top of the reactor 100; it also includes a gas supply cylinder 104 for inputting carbon dioxide gas into the reactor 100, a first air inlet 105 and an air outlet 106 on the reactor 100, the output end of the gas supply cylinder 104 being connected to the first air inlet 105; and a steam generator 103 for inputting steam into the reactor 100, a second air inlet 107 on the reactor 100, the output end of the steam generator 103 being connected to the second air inlet 107.

[0032] In this scheme, the heating unit 400 in the reactor 100 heats the reaction environment, the gas supply cylinder 104 introduces CO2 through the first air inlet 105, the steam generator 103 inputs steam through the second air inlet 107, the water in the water storage pan 307 is heated and vaporized, and together with CO2, it reacts with the steel slag on the baffle 205 to undergo a carbonation reaction. The pressure relief valve 108 automatically releases air when the internal pressure exceeds the limit. Through the synergistic effect of the heating unit 400, the gas supply cylinder 104, and the steam generator 103, the temperature, humidity, and gas flow rate can be controlled and adjusted. Combined with the vaporization and water replenishment in the water storage pan 307, the reaction efficiency of steel slag and CO2 is improved.

[0033] In one embodiment, the reactor 100 is provided with a controller for controlling the opening or closing of the heating unit 400, the steam generator 103 and the gas supply unit, and for setting the operating time of the heating unit 400, the steam generator 103 and the gas supply unit.

[0034] With this approach, the controller integrates control modules for the heating unit 400, steam generator 103, and gas supply unit. It can preset parameters such as heating temperature, steam generation time, and CO2 injection rate, and automatically start and stop each component according to the set program. Since the controller is a commonly used technology in this field and is not the key improvement point of this utility model, it will not be described in detail.

[0035] Alternatively, the reactor 100 may be connected to an internally interconnected box 101. The box 101 is provided with a box door 102. The carbon slag is placed on the partition 205 through the box door 102. The box 101 is connected to the reactor 100. After opening the box door 102, the steel slag can be placed on the partition 205 through the box door 102. Closing the box door 102 forms a closed reaction space.

[0036] In one embodiment, a first mounting base 201 and a second mounting base 202 are connected to the inner side of the housing 101. A first rotating shaft 203 is rotatably connected to the first mounting base 201, and a second rotating shaft 3071 is rotatably connected to the second mounting base 202. A first pin seat 204 is connected to the bottom of the partition 205. The first pin seat 204 is fixedly connected to the first rotating shaft 203. A drive unit 200 is connected to the outside of the reactor 100. The output end of the drive unit 200 is connected to the first rotating shaft 203. The drive unit 200 is used to drive the first rotating shaft 203 to reciprocate. A first limiting member is connected between the partition 205 and the first rotating shaft 203.

[0037] In this scheme, the drive unit 200 drives the first rotating shaft 203 to rotate back and forth, causing the partition 205 to swing synchronously through the first pin seat 204. The first limiting member restricts the swing angle of the partition 205, so that the steel slag swings evenly on the partition 205. The reciprocating swing of the partition 205 can increase the contact area between the steel slag and CO2 and water vapor, avoid material accumulation, and improve the gas-solid reaction rate.

[0038] In one embodiment, the second mounting base 202 is located below the first mounting base 201. A second rotating shaft 3071 is rotatably connected to the second mounting base 202. A second pin seat 3072 is fixedly connected to the second rotating shaft 3071. The second pin seat 3072 is fixedly connected to the bottom of the water storage tray 307. A second limiting member is provided between the water storage tray 307 and the second rotating shaft 3071. The limiting member is used to restrict the movement of the water storage tray 307 within a range of 15 degrees.

[0039] With this design, the water storage pan 307 is fixed to the second rotating shaft 3071 by the second pin seat 3072, and the second limiting member restricts its swing within a 15-degree range. It swings synchronously with the movement of the partition plate 205, increasing the surface area of ​​the water in the pan for uniform heating and vaporization. The limited swing of the water storage pan 307 can accelerate the evaporation of water vapor, allowing the water vapor to contact the steel slag more evenly through the partition plate 205.

[0040] In one embodiment, a water storage tank 300 is provided on the inner wall of the housing 101, and a water inlet 109 for filling the water storage tank 300 is provided on the outside of the housing 101. A first sealing cylinder 301 is installed inside the housing 101, and a first push rod 304 is connected to the first sealing cylinder 301. The lower end of the first push rod 304 is inserted into the first sealing cylinder 301 and connected to a first piston. A first pressure plate 306 is connected to the upper end of the first push rod 304, and a first spring 305 is sleeved on the first push rod 304. The ends of the first sealing cylinder 301 abut against the first pressure plate 306 and the first sealing cylinder 301 respectively. The inlet end of the first sealing cylinder 301 is connected to a first inlet pipe 302, and the other end of the first inlet pipe 302 is connected to the water storage tank 300. The outlet end of the first sealing cylinder 301 is connected to a first outlet pipe 303, and the other end of the first outlet pipe 303 is connected to the water storage pan 307 for replenishing water to the water storage pan 307. The side of the water storage pan 307 is provided with a return water box 308, and the top inner side of the return water box 308 is provided with multiple [unclear text - possibly related to the water storage pan 307]. 7. Through-holes are connected. When the water level in the water storage pan 307 reaches the positions of the multiple through-holes, water flows into the return water box 308 through the through-holes. A second sealing cylinder 309 is provided inside the housing 101. A second piston is slidably connected inside the second sealing cylinder 309. A second push rod 312 is connected to the second piston. A second pressure plate 314 is connected to the upper end of the second push rod 312. A second spring 313 is sleeved on the second push rod 312. The two ends of the second spring 313 abut against the second pressure plate 314 and the second sealing cylinder 309, respectively. A pressure roller 2041 is connected to one end of the first pin seat 204 near the first sealing cylinder 301 and the second sealing cylinder 309. When the first rotating shaft 203 rotates, the pressure roller 2041 abuts against the first pressure plate 306 and the second pressure plate 314. The water inlet end of the second sealing cylinder 309 is connected to a second water inlet pipe 311. The other end of the second water inlet pipe 311 is connected to the return water box 308. The water outlet end of the second sealing cylinder 309 is connected to a second water outlet pipe 310. The other end of the second water outlet pipe 310 is connected to the water storage tank 300.

[0041] In this scheme, when the first rotating shaft 203 rotates, the pressure roller 2041 presses the first pressure plate 306, pushing the first push rod 304 to compress the first spring 305, causing the first piston in the first sealing cylinder 301 to squeeze water into the water storage pan 307. When the first rotating shaft 203 rotates in the opposite direction, the first pressure plate 306 resets under the action of elasticity, and then the first piston draws water from the water storage tank 300. When the water level in the water storage pan 307 exceeds the through hole, water flows into the return water box 308. When the pressure roller 2041 presses the second pressure plate 314, the second sealing cylinder 309 draws the water from the return water box 308 back to the water storage tank 300 through the second water outlet pipe 310, forming a water circulation. Automatic water replenishment and return of the water storage pan 307 are achieved through mechanical linkage, without the need for external power, saving energy, while maintaining a stable water level, ensuring continuous water vapor generation, and improving the continuity of the reaction.

[0042] In one embodiment, the first pressure plate 306 and the second pressure plate 314 are located above the water storage pan 307. When the first pressure plate 306 and the second pressure plate 314 move, they cause the water storage pan 307 to rotate around the second rotating shaft 3071.

[0043] With this scheme, when the first pressure plate 306 and the second pressure plate 314 are pressed down, the water storage pan 307 is rotated around the second rotating shaft 3071, thereby further promoting water vapor evaporation.

[0044] In one embodiment, both the first limiting member and the second limiting member include a first baffle 500 for fixed installation on the first rotating shaft 203 and the second rotating shaft 3071; a U-shaped rod 501 for installation on the bottom of the partition 205 and the water storage tray 307; two second baffles 502 symmetrically installed on the U-shaped rod 501 and equidistantly distributed on both sides of the first baffle 500, wherein the first baffle 500 is slidably connected to the U-shaped rod 501; and two third springs 503, each sleeved on the U-shaped rod 501, wherein the two ends of the third springs 503 abut against the first baffle 500 and the second baffle 502 respectively.

[0045] In this scheme, the first baffle 500 is fixed on the first rotating shaft 203 and the second rotating shaft 3071, and the U-shaped rod 501 is connected to the partition 205 or the water storage tray 307. When the partition 205 or the water storage tray 307 swings, the first baffle 500 slides on the U-shaped rod 501 and compresses the third spring 503. The force of the third spring 503 and the two second baffles 502 limits its swing angle to within 15 degrees.

[0046] In one embodiment, the partition 205 is provided with a perforated portion 206, and the edge of the partition 205 extends upward to form an edge 207. The perforated portion 206 of the partition 205 allows water vapor to diffuse upward, while the edge 207 prevents steel slag from falling, ensuring that the steel slag is evenly spread and fully contacts the gas.

[0047] Optionally, the reactor 100 may be provided with a top cover 110.

[0048] In operation, the following steps are taken: First, open the box door 102 and lay gauze on the partition 205. Then, evenly place the steel slag on the gauze and inject water into the water storage tank 300 through the water inlet 109. Close the box door 102 to form a sealed space. Next, set the temperature of the heating unit 400, the working time of the steam generator 103, and the CO2 injection rate of the gas supply cylinder 104 using the controller. After startup, the heating unit 400 heats up, and the steam generator 103 inputs steam through the second air inlet 107. The water in the water storage pan 307 vaporizes upon heating. The steam diffuses upwards through the perforated portion 206 of the partition 205 and passes through the gauze to contact the steel slag. The CO2 is then introduced into the gas supply cylinder 104 through the first air inlet 105. O2 diffuses downwards from the top, and both react with the steel slag on the gauze to undergo a carbonation reaction. Simultaneously, the drive unit 200 drives the first rotating shaft 203 to rotate back and forth, causing the partition 205 to swing and press the first pressure plate 306 and the second pressure plate 314 through the pressure roller 2041, which in turn causes the water storage pan 307 to swing and rotate, accelerating the vaporization of the water. The first sealing cylinder 301 and the second sealing cylinder 309 work together to automatically replenish and return water to the water storage pan 307, forming a water cycle. During the reaction, the pressure relief valve 108 monitors the pressure in real time and automatically releases pressure when the limit is exceeded. After the set time is reached, all components are shut off, and after the pressure is released to normal pressure, the box door 102 is opened to remove the steel slag sample from the gauze, completing the carbon fixation reaction.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
