[0038] Embodiment 1

[0039] Reference Figure 1 For the first embodiment of the present application, a carbon fiber material microwave pyrolysis and tail gas purification treatment device is provided, which comprises a burning assembly 100, a detection assembly 200 and a purification assembly 300. The burning assembly 100 comprises an incinerator 101, a heat dissipation pipe 102 arranged in the incinerator 101, an air inlet pipe 103 communicated with the incinerator 101, a gas processor 104 connected with the air inlet pipe 103, a combustion chamber 105 connected with the gas processor 104, an air outlet pipe 106 communicated with the combustion chamber 105 and the incinerator 101, and a microwave output cabinet 107 communicated into the incinerator 101. The heat dissipation pipe 102 is symmetrically arranged at the front and rear ends of the incinerator 101, the gas processor 104 is a magnetized and ionized gas processor, and the exhaust gas is magnetized and ionized; natural gas is also introduced into the combustion chamber 105 for combustion support; the microwave output cabinet 107 is provided with a plurality of microwave output cabinets 107, and the microwave output cabinet 107 supplies heat into the incinerator 101.

[0040] After the material is fed into the incinerator 101, the microwave output cabinet 107 is started, which can generate a preheating zone and a high-temperature pyrolysis zone. The preheating zone has a temperature of 350 degrees, which is heated by natural gas heating and waste gas combustion heat. The high-temperature pyrolysis zone uses high-power microwaves of 915 MHz and 2450 MHz to instantaneously heat the material, causing the surface resin and fiber to separate and produce waste gas. At this time, the waste gas enters the gas processor 104 through the gas inlet pipe 103. The magnetized and ionized gas processor 104 rearranges the molecular structure, making the gas more combustible. After magnetization and ionization, the waste gas enters the combustion chamber 105, where natural gas is introduced to assist combustion. The waste gas produces heat after combustion, which is reused to heat the incinerator 101 through the gas outlet pipe 106, forming a closed loop of heat energy recycling. The pyrolyzed material is cooled by the heat dissipation pipe 102 and then taken out.

[0041] The microwave output cabinet 107 uses a high-power power supply of 915-2450 MHz. High-frequency microwaves pass through the generator box, enter the microwave converter, and then sequentially enter the microwave adjustment device to directly act on the surface of the product. This allows the product to instantaneously reach a high temperature (around 800-850 degrees) and undergo pyrolysis, causing the resin and product to separate.

[0042] The process flow is as follows: The material is automatically transported to the preheating zone by the stainless steel mesh belt system. In the preheating zone, the material is heated to 350 degrees using natural gas heating and waste gas combustion heat to ensure uniform heating, preparing for the high-temperature pyrolysis stage. Next, the material is transported to the high-temperature pyrolysis zone, where high-power microwaves of 915 MHz and 2450 MHz are used for instantaneous heating, achieving an efficient and uniform pyrolysis process. At this time, the fiber in the material begins to separate from the surface resin, producing pyrolysis gas.

[0043] During the pyrolysis process, the generated waste gas first passes through a magnetization and ionization device for ionization treatment. This process makes the composition of the pyrolysis gas more pure, which helps subsequent energy recovery. The ionized gas is then burned with natural gas, and the released heat energy is effectively recycled to the preheating zone, forming a high-efficiency heat energy recycling system that maximizes energy utilization throughout the entire process.

[0044] After pyrolysis and heat treatment, the product enters the cooling stage, where the cooling system is designed to effectively remove residual heat, ensuring stable and safe material temperature. The cooled product then undergoes physical processing, resulting in high-quality carbon fiber. This process not only achieves efficient material conversion and heat energy recovery but also enhances resource utilization efficiency.

[0045] Reference Figure 14The heating process of the microwave output cabinet 107 starts from the magnetron generating high-frequency microwaves, which are uniformly propagated into the incinerator 101. When the material is exposed to microwaves, the water molecules inside the material absorb microwave energy, rapidly vibrate and convert into heat energy, so that the material rapidly heats up. Since microwaves can penetrate materials and achieve uniform heating, the heating efficiency is effectively improved and thermal stress is reduced. After heating is completed, the material reaches the preset processing temperature, and then cooling and subsequent processes are performed.

[0046] Embodiment 2

[0047] With reference to Figures 2-13 For the second embodiment of the present application, in order to treat the waste gas generated after pyrolysis, a detection assembly 200 is arranged in the device, which includes an exhaust pipe 201 connected with the incinerator 101, a spray tower 202 connected with the exhaust pipe 201, a treatment chamber 203 connected with the spray tower 202, a probe 204 and an exhaust fan 205 arranged in the treatment chamber 203, a drive box 206 arranged outside the treatment chamber 203, a first sprocket 207 and a second sprocket 208 symmetrically arranged in the drive box 206, a chain 209 meshing with the first sprocket 207 and the second sprocket 208, a drive rod 210 connecting the exhaust fan 205 and the first sprocket 207, a fixed block 211 arranged on the chain 209, a sliding block 212 slidingly connected with the drive box 206, a sliding frame 213 and a connecting rod 214 fixedly arranged on the sliding block 212. The spray tower 202 is a desulfurization and dust removal spray tower, the bottom of the treatment chamber 203 is communicated with a smoke inlet pipe 203a, and the top of the treatment chamber 203 is communicated with a chimney 203b; the probe 204 is arranged at the outlet of the smoke inlet pipe 203a to monitor the waste gas index, and the exhaust fan 205 is arranged in the treatment chamber 203, and a spiral guide groove 203c is further arranged on the inner wall of the treatment chamber 203. The rotating shaft of the exhaust fan 205 is fixedly connected with one end of the drive rod 210, and the other end of the drive rod 210 is fixedly connected with the rotating shaft of the first sprocket 207; a sliding groove 206a is formed on the inner wall of the drive box 206, and the sliding block 212 is embedded in the sliding groove 206a; the sliding groove 206a is horizontally arranged transversely, the sliding frame 213 is rectangular, the sliding frame 213 is vertically fixed on the sliding block 212, the fixed block 211 is rotatably arranged on the chain 209, and the fixed block 211 is embedded in the sliding frame 213. The connecting rod 214 is fixed on the side wall of the sliding block 212, the connecting rod 214 extends out of the drive box 206, and the end of the connecting rod 214 is fixedly connected with the end of the piston 308.

[0048] Through the above scheme, with reference to Figures 2-11, the exhaust gas is discharged from the incinerator 101 through the exhaust pipe 201 to the spray tower 202, and is desulfurized by the desulfurization and dust removal spray tower, and then enters the treatment chamber 203 through the smoke inlet pipe 203a for deep purification; a detector 204 is arranged at the outlet of the smoke inlet pipe 203a to monitor harmful substances, and after the monitoring exceeds the standard, the upper computer starts the exhaust fan 205 to start rotating, the detector 204 sends an electrical signal to the upper computer and controls the exhaust fan 205 to start as a conventional technical means, which will not be described here. The exhaust fan 205 can adjust the speed and wind power according to the size of the exhaust gas index. In order to adjust the input amount of catalyst according to the speed of the exhaust fan 205, a driving rod 210 is fixed on the exhaust fan 205, and the exhaust fan 205 can drive the first sprocket 207 at the other end of the driving rod 210 to rotate synchronously, that is, the driving chain 209 starts to move. The fixed block 211 is fixed on the chain 209, which can be approximately considered as fixed on a point of the chain 209. The fixed block 211 moves in a circular path with the chain 209, and the fixed block 211 is embedded in the sliding frame 213. The up and down movement of the fixed block 211 does not affect the vertically arranged sliding frame 213. Therefore, the left and right movement of the fixed block 211 will exert force on the sliding frame 213, that is, the fixed block 211 moves with the chain 209 to drive the sliding frame 213 to move horizontally. The sliding frame 213 is fixed with the sliding block 212, and the sliding frame 213 can make the sliding block 212 move horizontally left and right in the sliding groove 206a, and drive the connecting rod 214 on the sliding block 212 to extend into and out of the driving box 206, converting the rotating force of the exhaust fan 205 into the horizontal movement of the connecting rod 214. The extension and retraction frequency of the connecting rod 214 can be adjusted according to the speed of the exhaust fan 205.

[0049] In order to add catalyst to the treatment chamber 203, refer to Figures 12-13The device is provided with a purification assembly 300, including a purification chamber 301, liquid inlet pipe 302 and liquid outlet pipe 303 opened in front and back of the purification chamber 301, liquid storage tank 304 communicated with the liquid inlet pipe 302, nozzle 305 communicated to the processing chamber 203 from the liquid outlet pipe 303, transfer cavity 306 opened in the purification chamber 301, connecting cavity 307 communicated with the transfer cavity 306 and the liquid inlet pipe 302, piston 308 fixedly connected with the connecting rod 214, channel 309 opened in the center of the piston 308, through hole 310 opened in the rod part of the piston 308, movable part 311 arranged at the channel 309 and the liquid inlet pipe 302, the movable part 311 including plug ball 312 and spring 313. The liquid storage tank 304 inputs catalyst into the purification chamber 301 from the liquid inlet pipe 302; the liquid outlet pipe 303 is connected out from the transfer cavity 306. The piston 308 is slidingly arranged in the transfer cavity 306, the radial diameter of the rod part of the piston 308 is smaller than the radial diameter of the end part of the piston 308; the channel 309 extends inward from the top of the piston 308, and is in a cylindrical shape, and the channel 309 at the end part of the piston 308 is narrower than the channel 309 at the rod part of the piston 308. The through hole 310 is arranged with a plurality of through holes, which are uniformly distributed on the side wall of the rod part of the piston 308. The movable part 311 is arranged with two, one is arranged at the rod part of the piston 308, and the other is arranged at the pipe opening of the liquid inlet pipe 302 in the purification chamber 301. In the movable part 311 in the channel 309, the plug ball 312 is in the channel 309 at the rod part of the piston 308, the radial diameter of the plug ball 312 is larger than the radial diameter of the channel 309 at the end part of the piston 308, one end of the spring 313 is connected with the plug ball 312, and the other end is connected with the inner wall of the channel 309; in the movable part 311 at the liquid inlet pipe 302, the plug ball 312 is at the pipe opening of the liquid inlet pipe 302, the radial diameter of the plug ball 312 is larger than the radial diameter of the inner wall of the liquid inlet pipe 302, one end of the spring 313 is connected with the plug ball 312, and the other end is connected with the inner wall of the purification chamber 301, the springs 313 in the two movable parts 311 are in compressed state in natural state.

[0050] By the above scheme, the piston 308 is fixedly connected with the connecting rod 214, and the extension and contraction of the connecting rod 214 is the extension and contraction of the piston 308 in the transfer cavity 306. In the natural state, the catalyst in the liquid storage tank 304 flows into the liquid inlet pipe 302, and the pipe opening of the liquid inlet pipe 302 and the blocking ball 312 in the channel 309 close the pipeline, so that the catalyst cannot normally flow. The piston 308 extends into the liquid inlet pipe 302, and the piston 308 approaches the connecting cavity 307. The space between the two blocking balls 312, i.e. the space between the connecting cavity 307 and the end channel 309 of the piston 308, becomes smaller, the internal gas pressure increases, the catalyst is discharged outward, the blocking ball 312 at the pipe opening of the liquid inlet pipe 302 is pushed to death at the pipe opening, and the space is still closed, while the blocking ball 312 in the channel 309 is pushed open and squeezes the spring 313 connected thereto. The catalyst between the two blocking balls 312 is discharged to the transfer cavity 306 through the through hole 310 and moves along the liquid outlet pipe 303 until it is injected into the treatment chamber 203 from the nozzle 305. When the piston 308 moves away from the liquid inlet pipe 302 and contracts in the transfer cavity 306, the space between the two blocking balls 312 becomes larger, the gas pressure becomes smaller, and the relative two blocking balls 312, i.e. the relative gas pressure in the liquid inlet pipe 302 and the transfer cavity 306, exerts a force on the two blocking balls 312. The blocking ball 312 in the channel 309 is abutted at the channel opening 309 to close the channel 309, and the blocking ball 312 at the pipe opening of the liquid inlet pipe 302 is abutted open and squeezes the spring 313 below it. The catalyst in the liquid inlet pipe 302 is sucked into the connecting cavity 307. The two movement processes can be divided into: when the piston 308 extends into the purification chamber 301, the catalyst between the two blocking balls 312 is discharged to the liquid outlet pipe 303 and discharged through the nozzle 305, and when the piston 308 contracts in the purification chamber 301, the catalyst in the liquid storage tank 304 is sucked between the two blocking balls 312. When the connecting rod 214 cyclically drives the piston 308 to extend and contract, the catalyst in the liquid storage tank 304 can be continuously extracted and discharged into the treatment chamber 203. Referring to Figure 13 the arrow direction, this process can also be accelerated according to the extension and contraction frequency of the piston 308, i.e. the higher the exhaust gas index, the faster the rotation speed of the exhaust fan 205, so that the catalyst in the nozzle 305 can be sprayed faster. The exhaust gas enters the treatment chamber 203 from the smoke inlet pipe 203a and is finally discharged from the chimney 203b connected at the top. When harmful substances are monitored, the exhaust fan 205 blows the exhaust gas vertically upward from the side, so that the exhaust gas flow is disturbed and fully mixed with the catalyst, improving the catalytic efficiency and making the exhaust gas move along the inner wall to the spiral guide groove 203c, forming a turbine to accelerate the discharge of the chimney 203b.

[0051] It should be noted that the above examples are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced, without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
