Description

Technical Field

[0001] This invention relates to the field of carbon neutrality technology, specifically to an experimental device for detecting the carbon sequestration efficiency of solid waste. Background Technology

[0002] The production of acetylene generates a large amount of calcium carbide slag waste. Even after dehydration, the moisture content of this waste is still as high as 40% to 50%, and it is in a paste-like state. This makes it very easy to leak during transportation, causing pollution to the road environment. At the same time, the long-term accumulation of calcium carbide slag not only occupies a large amount of land resources, but its strong alkaline properties also seriously erode the soil structure and damage the surrounding ecological environment, becoming a prominent problem restricting the green development of related industries. To achieve the goal of "turning harm into benefit and waste into treasure," the industry has explored various comprehensive utilization pathways for calcium carbide slag, including replacing limestone in cement production, producing quicklime for reuse as a raw material for calcium carbide, preparing chemical products, processing building materials, and applying them to environmental remediation. Among these, the technological path of reacting calcium carbide slag with CO2 to generate cementing substances can not only achieve the resource reuse of solid waste but also contribute to the achievement of carbon neutrality goals, making it a highly valuable development direction.

[0003] Current carbon sequestration experimental devices mostly employ simple kettle or tank structures. Solid waste is typically piled at the bottom of the reactor, with CO2 gas introduced from the bottom. Due to the high bulk density and low porosity of solid waste particles, gas easily forms short-circuit flow or channeling phenomena within the material layer. This means the gas tends to pass rapidly along the path of least resistance (such as the container wall edge), failing to penetrate evenly and sufficiently into the internal areas of the solid waste. This results in a small contact area between the solid waste and CO2, uneven reaction, and a large amount of solid waste located in the center of the material pile failing to participate in the reaction, leading to low carbon sequestration efficiency. Furthermore, these devices cannot simulate the reaction rate of solid waste under different loading conditions and with CO2. These problems directly restrict the efficiency and large-scale application of carbide slag waste treatment. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] The acetylene production process generates a large amount of calcium carbide slag waste. The technical path of reacting calcium carbide slag with CO2 to form cementing substances can not only realize the resource reuse of solid waste, but also help achieve the goal of carbon neutrality, making it a highly valuable development direction. Due to the huge volume of calcium carbide slag waste, it needs to be processed in large quantities. However, calcium carbide slag waste cannot fully react with high concentrations of CO2 when stockpiled, and the reaction rate of calcium carbide slag waste with CO2 under different stockpiling conditions is unknown. These problems directly restrict the efficiency and large-scale application of calcium carbide slag waste treatment.

[0020] Please see Figure 1-14 This invention provides a technical solution: an experimental device for detecting the carbon sequestration efficiency of solid waste, comprising: a tank 10, a handle 101 fixedly installed at the outer end of the tank 10 for easy movement of the tank 10 by gripping the handle 101, a pull-out plate 102 configurably installed on one side of the tank 10, the pull-out plate 102 being fixed to the tank 10 by a fixing component, a controller fixedly installed at the top of the tank 10, and an air inlet pipe 103 fixedly installed on the pull-out plate 102. The inner end of the inlet pipe 103 passes through the side wall of the pull-out plate 102 and is located inside the tank 10. The outer end of the inlet pipe 103 is connected to the CO2 delivery pipe and the CO2 concentration detector. The top of the tank 10 is fixedly installed with the outlet pipe 104. The inner end of the outlet pipe 104 is connected to the inner end of the tank 10, and the outer end is connected to the CO2 gas collection pipe and the CO2 concentration detector. The outlet pipe 104 is used to detect the CO2 concentration inside the tank 10 and the CO2 concentration outside the tank 10, so as to make a judgment on the degree of carbon fixation of solid waste.

[0021] The bottom plate 20 is installed on the inner wall of the bottom end of the tank 10 via a drawer rail, and one end is fixedly connected to the inner wall of the bottom end of the pull plate 102 via a connecting plate 202. The other end is fixedly installed with a docking plate 201. The upper end of the bottom plate 20 is fixedly installed with an mounting plate 203 via a column. The inner liner 60 is fixed on the mounting plate 203. When the pull plate 102 is fixed on the outer wall of the tank 10, the docking plate 201 contacts the inner wall of the other end of the tank 10. The inner liner 60 on the mounting plate 203 is located at the center of the tank 10 and directly below the adjustment component fixed at the upper end of the tank 10. By opening the pull plate 102 and pulling the mounting plate 203 outward, it is easy to remove the inner liner 60 and quickly replace the solid waste inside the inner liner 60.

[0022] The inner core component is fixed to the upper center of the mounting plate 203, and the outer wall component is fixed to the upper outer side of the mounting plate 203. Several holes are evenly opened on the side wall of the inner liner 60. A concentric perforated cylinder 602 is set in the middle of the inner liner 60. A circular hole 603 communicating with the perforated cylinder 602 is opened at the bottom of the inner liner 60. The inner liner 60 is filled with solid waste. When the inner liner 60 is placed on the upper end of the mounting plate 203, the perforated cylinder 602 is sleeved on the outer side of the inner core component. At the same time, the outer side of the inner liner 60 is in contact with the outer component. The inner core component heats and introduces CO2 into the solid waste in the inner liner 60 from the inside out, and the outer wall component heats and introduces CO2 into the solid waste in the inner liner 60 from the outside in. This can maintain a constant temperature reaction environment, avoid a large temperature gradient of the solid waste in the inner liner 60, and force the high concentration of CO2 to fully and deeply react with the solid waste material (such as carbide slag waste), thereby improving the accuracy of experimental data.

[0023] An adjusting component, installed at the upper end of the tank 10, is used to adjust the gaps and density of solid waste materials inside the inner liner 60. By squeezing the solid waste materials inside the inner liner 60 through the adjusting component, the gaps and density of the solid waste materials are adjusted, thereby determining the reaction rate of CO2 gas and solid waste materials at different densities. Different loading conditions can be simulated to study the effect of pressure on carbon fixation rate, so as to obtain the optimal loading capacity and improve the efficiency of carbide slag waste treatment.

[0024] In one embodiment, please refer to Figure 4 — Figure 8 The inner core component includes a core cylinder 401 fixed to the upper end of the mounting plate 203. Several cross-arranged second electric heating rods 402 and second gas boxes 403 are fixedly installed on the inner end of the core cylinder 401. The second electric heating rods 402 are connected to an external power supply and a thermostat for heating the interior of the inner liner 60. Several exhaust pipes 404 are evenly fixedly installed on the side wall of the second gas box 403. The exhaust pipes 404 pass through the side wall of the core cylinder 401, and the outer end of the exhaust pipes 404 is flush with the outer end of the core cylinder 401. A support pipe 405 is fixedly installed at the bottom end of each second gas box 403. The support pipe 405 passes through the mounting plate 203 and is fixedly connected to an annular diverter pipe 1031. The diverter pipe 1031 and the air inlet pipe 103 are fixedly connected and communicate with each other, allowing high concentrations of CO2 gas to pass through.

[0025] When a high concentration of CO2 is introduced into the inlet pipe 103 through the external CO2 gas supply pipe, the CO2 enters the diversion pipe 1031, then the support pipe 405, and finally the second gas box 403 and is exhausted into the orifice 602 inside the inner liner 60 through the exhaust pipe 404. The CO2 gas enters the inner liner 60 through the holes and reacts with the solid waste. At the same time, the second electric heating rod 402 is energized to heat the solid waste in the inner liner 60 from the inside out.

[0026] In one embodiment, please refer to Figure 6 — Figure 10 The outer wall component includes several arc-shaped fixing plates 301, which are arranged in a circle on the upper end of the mounting plate 203. Each fixing plate 301 has a clamping plate 303 elastically connected to its inner end. The clamping plate 303 and the mounting plate 203 are slidably connected. The upper end of the mounting plate 203 is provided with a sliding groove 309. The lower end of the clamping plate 303 is fixedly installed with a slider 308. Both the sliding groove 309 and the slider 308 are convex, and the lower end of the slider 308 is slidably inserted into the sliding groove 309, allowing the clamping plate 303 to slide on the mounting plate 203.

[0027] Each clamping plate 303 has an outwardly inclined guide plate 304 fixedly installed at its upper end to guide the inserted inner liner 60. Several air holes 305 are evenly opened on the side wall of the clamping plate 303. A first electric heating rod 319 and a first air box 306 are fixedly installed at the outer end of each clamping plate 303. The first electric heating rod 319 is connected to an external power supply and a thermostat. Several first springs 302 are evenly fixedly installed between the first air box 306 and the fixing plate 301. The clamping plate 303 can slide on the mounting plate 203 by squeezing the first springs 302.

[0028] Each first gas box 306 has a corresponding mounting hole 305 on its side wall, and the mounting hole and the gas hole 305 are concentric. A connecting pipe 307 is fixedly installed at the lower end of each first gas box 306. The outer end of the connecting pipe 307 is fixedly connected to and communicates with the diversion pipe 1031. When the external CO2 gas supply pipe inputs high concentration CO2 into the inlet pipe 103, the CO2 enters the diversion pipe 1031, then enters the connecting pipe 307, and finally enters the first gas box 306. The gas hole 305 enters the inner side of the inner liner 60 from the outer end and reacts with the solid waste. At the same time, the first electric heating rod 319 is energized to heat the solid waste in the inner liner 60 from the outside to the inside.

[0029] In one embodiment, please refer to Figure 7 — Figure 8 and Figure 11 —12, Each first gas box 306 is equipped with several air intake components. The air intake components include a fixed tube 310 fixed on the side wall of the first gas box 306. One end of the fixed tube 310 is inserted into the air hole 305 and is flush with the inner end of the clamping plate 303. The other end is inserted into the first gas box 306. Several air grooves 312 are evenly opened on the inner wall of one end of the fixed tube 310. Several air inlets 311 are evenly opened on the other end of the fixed tube 310. The high concentration of CO2 gas in the first gas box 306 enters the fixed tube 310 through the air inlets 311.

[0030] Each fixed tube 310 has a sliding tube 313 slidably installed at its inner end. A piston 314 is fixedly installed at one end of the sliding tube 313. A second spring 315 is fixedly installed between the piston 314 and the fixed tube 310. A sealing ring 316 is fixedly sleeved on the outer wall of the sliding tube 313. The outer sidewalls of the piston 314 and the sealing ring 316 are slidably connected to the inner wall of the fixed tube 310. Several strip-shaped holes are evenly opened on the sidewall of the sliding tube 313. The strip-shaped holes are located between the piston 314 and the sealing ring 316. The sliding tube 313 can slide in the fixed tube 310 by stretching the second spring 315. Several strip-shaped exhaust holes 318 are opened on the outer sidewall of each sliding tube 313. A cone head 317 is fixedly installed at the end of each sliding tube 313 away from the piston 314. When the second spring 315 is in a balanced state, the cone head 317 is located inside the fixed tube 310.

[0031] When CO2 gas enters the first gas box 306, it enters the fixed tube 310. As the amount of CO2 gas entering increases, it applies a thrust to the piston 314. The piston 314 slides the sliding tube 313 in the fixed tube 310 by stretching the second spring 315, and passes through the hole on the inner liner 60 through the cone head 317 and is inserted into the inner liner 60. At the same time, the piston 314 slides to the inside of the gas groove 312. The CO2 gas enters the sliding tube 313 through the gas groove 312 and the strip hole, and then enters the solid waste in the inner liner 60 through the exhaust hole 318, so that the high concentration of CO2 comes into full contact with the solid waste material.

[0032] In one embodiment, please refer to Figure 9 and Figure 12 — Figure 13 Several positioning posts 604 are evenly fixedly installed at the bottom of the inner liner 60. The mounting plate 203 has positioning holes 204 corresponding to the positioning posts 604. When the inner liner 60 is placed on the upper end of the mounting plate 203, the positioning posts 604 are inserted into the positioning holes 204 to complete the positioning of the inner liner 60. At the same time, the sliding tube 313 is located at the outer end of the hole in the inner liner 60, so that the sliding tube 313 can be accurately inserted into the inner liner 60. A handle 601 is fixedly installed at the upper end of the inner liner 60, which facilitates the taking and putting away of the inner liner 60.

[0033] In one embodiment, please refer to Figure 1 — Figure 4The adjusting component includes two parallel perforated plates 501, each in an annular shape. A horizontal plate is fixedly mounted on the upper end of one of the perforated plates 501 via a support rod 503. A threaded rod 504 is rotatably connected to the upper end of the horizontal plate, threaded through the upper side wall of the tank body 10. The other perforated plate 501 is slidably connected to the lower end of the first perforated plate 501 via a limiting post 502. The limiting post 502 has a convex cross-section and slides through the side wall of the upper perforated plate 501, fixing it to the lower perforated plate 501, allowing the lower perforated plate 501 to be positioned relative to the upper perforated plate. The lower end of 501 slides, and a pressure sensor (not shown in the figure) is installed between the two orifice plates 501. The controller, pressure sensor and temperature controller are electrically connected. By rotating the threaded rod 504, the orifice plate 501 can be driven to move inside the tank 10. When the orifice plate 501 moves towards the inner liner 60, the outer wall of the orifice plate 501 is located inside the inner liner 60. At the same time, the inner end of the orifice plate 501 is sleeved on the outer end of the orifice cylinder 602 to compress the solid waste located in the inner liner 60, simulating the solid waste under different loading conditions and CO2 reaction rate, so as to obtain the optimal loading capacity and improve the efficiency of carbide slag waste treatment.

[0034] When this device is in operation, the pull plate 102 is pulled outward by pulling the handle on the pull plate 102, which causes the bottom plate 20 to slide outward through the rails from the outside of the tank 10. The inner liner 60 containing solid waste is inserted into the upper end of the mounting plate 203. At the same time, the inner core component is inserted into the orifice 602, and the outer wall component is attached to the outer end of the inner liner 60. High-concentration carbon dioxide gas is introduced through the air inlet pipe 103, and the electric heating rod is activated by the controller to heat the solid waste from the inside out and from the outside in, while also introducing high-concentration carbon dioxide gas. At the same time, the threaded rod 504 can be rotated to compress the solid waste with the orifice plate 501, simulating the solid waste under different loading conditions and CO2 reaction rates. By detecting the CO2 concentration inside the tank 10 and the CO2 concentration outside the tank 10, the degree of carbon fixation of the solid waste can be judged to determine the optimal loading capacity and improve the efficiency of carbide slag waste treatment.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
