[0045] The technical solutions of the embodiments of this application 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 this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0046] This application provides a carbon removal device that can be used to remove carbon elements adhering to materials. For example, the carbon removal device can be a glass fiber carbon removal device. Glass fiber is obtained by pyrolysis of wind turbine blades. The carbon removal device can remove the carbon elements adhering to the glass fiber, transforming the black glass fiber obtained after the pyrolysis of wind turbine blades into white glass fiber, thereby obtaining glass fiber that meets market demands and achieving effective recycling of wind turbine blades.

[0047] refer to Figure 1 and Figure 2 The carbon removal equipment 100 includes a reaction chamber 10, a material conveying device 20, an air inlet pipe 30, a feeding device 40, a heating module 50, and a discharge port 60.

[0048] The reaction chamber 10 is a sealed cavity where the oxidation and decarbonization of the material takes place. The reaction chamber 10 includes a first end 11 and a second end 12. The first end 11 is the feed inlet, and the second end 12 is the discharge outlet.

[0049] A material conveying device 20 is disposed within the reaction chamber 10. The material conveying device 10 is used to carry and convey the material from the first end 11 to the second end 12. In some embodiments, the material may be glass fiber obtained from the pyrolysis of wind turbine blades, on which carbon elements are attached and require decarbonization. In other embodiments, the material may be other materials that require decarbonization.

[0050] The air intake pipe 30 is connected to the reaction chamber 10 and is used to introduce air into the reaction chamber 10. The air is used to react with the carbon elements attached to the material in an oxidation reaction. The position of the air intake pipe 30 can be set according to actual needs. Understandably, if the air intake volume of the air intake pipe 30 is too large, too much cold air entering the reaction chamber 10 will cause the temperature to drop; while if the air intake volume is too small, it cannot guarantee that there is enough oxygen inside the reaction chamber 10. Therefore, the air intake volume of the air intake pipe 30 can be adjusted according to needs to achieve intelligent control of the air intake volume.

[0051] The feeding device 40 is located at the first end 11 of the reaction chamber 10. The feeding device 40 is used to distribute the material onto the material conveying device 20. In practical applications, the feeding device 40 can be a feeding and spreading machine.

[0052] Heating modules 50 may be one or more, for example Figure 1 and Figure 2 As shown, it includes four heating modules 50. In practical applications, the number of heating modules 50 can be increased or decreased according to different material processing volumes. Understandably, the heating modules 50 adopt a modular design, each of which can be independently disassembled and assembled, facilitating maintenance and repair.

[0053] The heating module 50 is disposed within the reaction chamber 10 and located above the material conveying device 20. The heating module 50 is used to heat the material on the material conveying device 20, causing the carbon elements on the material to be oxidized and removed. It can be understood that since the heating module 50 does not directly contact the material, it actually heats the interior of the reaction chamber 10, maintaining a certain temperature inside the chamber, thereby indirectly heating the material. This allows the carbon elements adhering to the material to react with oxygen in the air, generating gaseous carbon dioxide, thus achieving the oxidation and removal of the carbon elements from the material.

[0054] The discharge port 60 is connected to the second end 12 of the reaction chamber 10 and is used to discharge the decarbonized material, such as decarbonized white glass fiber. In practical applications, an airlock device can be installed at the location of the discharge port 60 to achieve an airtight seal and prevent air from entering the reaction chamber 10 from the discharge port.

[0055] The carbon removal device 100 of this application embodiment can maintain an oxidizing atmosphere at a certain temperature inside the reaction chamber 10, so that the carbon elements attached to the material can react with oxygen in the air to generate gaseous carbon dioxide, thereby achieving the oxidation and removal of carbon elements on the material. For example, the carbon elements attached to glass fiber can be oxidized and removed, thereby realizing the transformation of black glass fiber obtained from the pyrolysis of wind turbine blades into white glass fiber, and the final glass fiber meets the market demand.

[0056] In some embodiments, continue to refer to Figure 1 andFigure 2 A gas outlet pipe 70 is arranged above each heating module 50 and outside the reaction chamber 10. The gas outlet pipe 70 is in communication with the inside of the reaction chamber 10 and is used to discharge the flue gas generated by the oxidation of carbon elements on the material. It can be understood that the flue gas contains carbon dioxide generated by the oxidation of carbon elements. In actual application, a valve can be arranged on the gas outlet pipe 70 to adjust the gas outlet amount.

[0057] In some embodiments, as shown in Figure 1 , the carbon removal device 100 further comprises a power structure 81, a skid 82, and a control box 83. The power structure 81 and the control box 83 can be arranged at the second end portion 12 of the reaction chamber 10, and the skid 82 is arranged at the bottom of the reaction chamber 10 to form the base of the reaction chamber 10. The power structure 81 is connected with the material conveying device 20 and is used to drive the material conveying device 20 to convey the material from the first end portion 11 to the second end portion 12. The power structure 81 can adjust the rotating speed according to the processing amount of the material to control the running speed of the material conveying device 20. The control box 83 is used to monitor and control the whole carbon removal device 100.

[0058] In some embodiments, referring to Figure 2 , the reaction chamber 10 is internally provided with a first shaft 13 and a second shaft 14, and the first shaft 13 and the second shaft 14 are both arranged in the horizontal direction. In some embodiments, the first shaft 13 can be arranged at the first end portion 11, and the second shaft 14 can be arranged at the second end portion 12. The material conveying device 20 comprises a chain plate conveying mechanism 21. The chain plate conveying mechanism 21 can be a closed loop chain structure formed by sequentially connecting a plurality of chain links. The material of the chain plate conveying mechanism 21 can be stainless steel or other high-temperature-resistant materials, which can withstand a high temperature of 700°C or below. One end of the chain plate conveying mechanism 21 is arranged around the first shaft 13, and the other end is arranged around the second shaft 14. The chain plate conveying mechanism 21 rotates around the first shaft 13 and the second shaft 14, for example, rotates in the clockwise direction from the perspective shown in Figure 2 , so as to convey the material from the first end portion 11 to the second end portion 12.

[0059] In some embodiments, at least one scraper 211 is arranged on the chain plate conveying mechanism 21. The scraper 211 is arranged in the vertical direction or forms a preset angle with the vertical direction, for example, forms a small angle with the vertical direction, that is, is slightly inclined in the vertical direction. In the process of rotating the chain plate conveying mechanism 21, the scraper 211 also rotates together, so as to scrape the material accumulated at the bottom of the reaction chamber 10 to the first end portion 11.

[0060] It can be understood that when the material enters the inside of the carbon removal device 100, a part of the material inevitably falls into the bottom of the reaction cavity 10, and accumulates over time. When the material falling into the bottom of the reaction cavity 10 accumulates to a certain thickness, the scraper 211 can scrape the falling material to the direction of the first end portion 11, that is, to the direction of the feeding device 40, and finally scrape the material to the chain plate conveying mechanism 21 at the material collecting port position of the first end portion 11, so that the material is re-conveyed on the chain plate conveying mechanism 21.

[0061] In some embodiments, an observation window can be provided on the reaction cavity 10, for example, an observation window such as a transparent glass window is provided at the position of the first end portion 11, which can be used to observe the material inside the reaction cavity 10.

[0062] In some embodiments, referring to Figures 3 to 5 The feeding device 40 includes a first cavity 41, a second cavity 42, a driving mechanism 43, and a transmission mechanism 44. The second cavity 42 is arranged below the first cavity 41 and communicates with the first cavity 41. It can be understood that the outside of the first cavity 41 and the second cavity 42 is also provided with a shell. The first cavity 41 is an air locking cavity, and the second cavity 42 is a material distribution cavity. The function of the air locking cavity is to prevent air from entering the inside of the reaction cavity 10 from the feeding port at the same time of feeding, so as to affect the carbon removal effect. The function of the material distribution cavity is to uniformly distribute the material on the chain plate conveying mechanism 21. Among them, the first cavity 41 is provided with an impeller 411, and the second cavity 42 is provided with a spiral structure 421. The driving mechanism 43 is connected with the impeller 411 and the spiral structure 421 through the transmission mechanism 44, for driving the impeller 411 and the spiral structure 421 to rotate. In actual application, the driving mechanism 43 can be a motor, the transmission mechanism 44 can include a chain or a belt, and a protective cover arranged outside the chain or the belt.

[0063] The spiral structure 421 can rotate around its central axis to distribute the material on the material conveying device 20, for example, to distribute the material on the chain plate conveying mechanism 21. The spiral structure 421 can uniformly distribute the material from the middle to both sides, and can also scatter the material into a loose state, increase the contact area of the material and oxygen in the air, and improve the oxidation efficiency of the carbon elements attached to the material. In addition, the spiral structure 421 can also form a closed structure inside the feeding device 40, so as to avoid external air entering the inside of the reaction cavity 10 through the feeding device 40 to affect the control of the air inlet amount.

[0064] In some embodiments, referring to Figure 6The chain plate conveying mechanism 21 is provided with a material height control device 22 above it, which can be a scraper, for example. The material height control device 22 is arranged at the material inlet end of the reaction cavity 10, which can prevent the material from accumulating too high and affecting the carbon removal efficiency. The chain plate conveying mechanism 21 is provided with a material blocking plate 23 on both sides, which can prevent the material from falling off from both sides of the chain plate conveying mechanism 21. The chain plate conveying mechanism 21 is provided with a perforated baffle 24 on both sides, which can move synchronously with the chain plate conveying mechanism 21 and has a material blocking effect. The baffle 24 can be uniformly distributed with a plurality of air holes, which can increase the contact area between the material and oxygen in the air and improve the oxidation efficiency of the carbon elements attached to the material.

[0065] In some embodiments, the side wall and the bottom wall of the reaction cavity 10 are provided with a plurality of air inlets, such as a plurality of air inlets 25 arranged on the side wall and a plurality of air inlets 26 arranged on the bottom wall. The plurality of air inlets are communicated with an air inlet pipeline 30 for inputting air into the reaction cavity 10. In practical applications, the plurality of air inlets 25 on the side wall and the plurality of air inlets 26 on the bottom wall can be uniformly distributed to ensure the uniformity of air inlet, which can ensure that the material at each position can be uniformly contacted with air, thereby improving the oxidation carbon removal efficiency.

[0066] In some embodiments, the air inlet pipeline connected with the air inlets 25 on the side wall and the air inlet pipeline connected with the air inlets 26 on the bottom wall can be provided with a flow detection device 27 and a valve for real-time control of the air inlet amount of each air inlet, so that the material in the equipment can be oxidized in an oxygen-rich environment to ensure the oxidation carbon removal efficiency.

[0067] In some embodiments, the carbon removal equipment 100 further comprises a chain plate tensioning device 28. The chain plate tensioning device 28 is arranged at the first end portion 11 of the reaction cavity 10, such as being mounted on the skid 82. The chain plate tensioning device 28 is used to keep the chain plate conveying mechanism 21 in tension. In some embodiments, the cooperation position of the chain plate tensioning device 28 and the skid 82 is provided with a sealing structure, so as to keep the reaction cavity 10 sealed and ensure the sealing of the inside of the carbon removal equipment 100.

[0068] In some embodiments, the carbon removal equipment 100 further comprises a micro differential pressure detection device 29. The micro differential pressure detection device 29 is arranged at the first end portion 11 of the reaction cavity 10 for real-time detection of the pressure inside the reaction cavity 10, real-time adjustment of the air inlet speed and air outlet speed according to the detected pressure, and guarantee of the pressure condition inside the carbon removal equipment 100.

[0069] In some embodiments, the second end portion 12 of the reaction cavity 10 can also be provided with a micro differential pressure detection device 29. That is, the first end portion 11 and the second end portion 12 of the reaction cavity 10 are both provided with a micro differential pressure detection device 29 for jointly detecting the pressure inside the reaction cavity 10.

[0070] In some embodiments, referenceFigure 7 and Figure 8 The heating module 50 comprises an upper cover 51, a heat preservation layer 52, and a plurality of heating resistors 53. The plurality of heating resistors 53 are arranged at intervals, and the heating resistors 53 are used to heat the material on the material conveying device 20, which can be indirect heating. The upper cover 51 is arranged above the plurality of heating resistors 53. The heat preservation layer 52 is arranged between the upper cover 51 and the plurality of heating resistors 53, and is used to achieve heat preservation. In actual application, the heating resistor 53 is internally designed with a heat detection system, which detects the temperature of the heating resistor 53 in real time, realizes high-temperature alarm and automatic power-off, and prevents damage of the resistance wire due to high temperature.

[0071] In some embodiments, the heating module 50 further comprises a plurality of electric heating protection tubes 54. The electric heating protection tube 54 is installed on the upper cover 51. For example, one end of the electric heating protection tube 54 is installed on one side of the upper cover 51 through a flange. The other side of the upper cover 51 can also be provided with a supporting device 55, and the other end of the electric heating protection tube 54 is installed in the supporting device 55. Each heating resistor 53 is installed inside one electric heating protection tube 54, which can increase the heat dissipation uniformity of the heating resistor 53, and can prevent the corrosion gas from affecting the service life of the resistance wire. The heating resistor 53 can be directly extracted from the electric heating protection tube 54 for replacement, which is convenient for maintenance.

[0072] In some embodiments, a thermocouple can also be arranged in each heating module 50 for real-time monitoring of the temperature of the heating module 50. When the temperature is detected to be too high, the heating module 50 is stopped to heat, which improves the safety of the equipment.

[0073] In some embodiments, as shown in Figure 8 The upper cover 51 is provided with a gas outlet 511.

The sealing box 283 is installed on the support frame 289 and is in a U-shaped groove structure and can be replaced. The sprocket shaft 284 is placed in the second bearing 288. The tension of the chain plate conveying mechanism 21 is adjusted by the screw rod 287. During the adjustment of the tension, the graphite packing 282 slides in the U-shaped groove of the sealing box 283, so that the opening position is always completely blocked, and the overall sealing performance of the carbon removal equipment 100 is ensured. The chain break detection device 285 is connected with the sprocket shaft 284 through the first bearing 286, so that the chain break detection can be performed in real time, and the safety of the carbon removal equipment 100 is improved.
