DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0037] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0038] Example 1

[0039] Reference Figure 1 The first embodiment of the present invention provides a carbon fiber material microwave cracking and exhaust gas purification device, comprising an incineration assembly 100, a detection assembly 200, and a purification assembly 300. The incineration assembly 100 comprises an incinerator 101, a heat dissipation pipe 102 disposed within the incinerator 101, an air inlet pipe 103 communicating with the incinerator 101, a gas processor 104 connected to the air inlet pipe 103, a combustion chamber 105 connected to the gas processor 104, an air outlet pipe 106 connecting the combustion chamber 105 and the incinerator 101, and a microwave output cabinet 107 connected to the incinerator 101. The heat dissipation pipes 102 are symmetrically disposed at the front and rear ends of the incinerator 101. The gas processor 104 is a magnetized ionization gas processor that magnetizes and ionizes the exhaust gas. Natural gas is also introduced into the combustion chamber 105 to assist combustion. A plurality of microwave output cabinets 107 are provided to supply heat to the incinerator 101.

[0040] After the material is fed into the incinerator 101, the microwave output cabinet 107 is activated, creating a preheating zone and a high-temperature cracking zone. The preheating zone is heated at 350°C using natural gas and heat from exhaust gas combustion. The high-temperature cracking zone uses high-power microwaves at 915 MHz and 2450 MHz, instantly heating the material and causing pyrolysis. This separates the surface resin from the fibers and produces exhaust gas. The exhaust gas then enters the gas processor 104 through the inlet pipe 103. The magnetized and ionized gas processor 104 rearranges the molecular structure, making the gas more combustible. After magnetization and ionization, the exhaust gas enters the combustion chamber 105, where natural gas is introduced to assist combustion. The exhaust gas combustion generates heat, which is then returned to the incinerator 101 through the outlet pipe 106 to provide heat, forming a closed loop for heat energy reuse. The pyrolyzed material is then cooled through the heat pipe 102 before being removed.

[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 continuously enter the microwave conditioning device in sequence before directly acting on the surface of the product. This instantly heats the product to a high temperature (around 800-850 degrees Celsius), causing it to crack and separate the resin from the product.

[0042] The process flow is as follows: the material is automatically conveyed to the preheating zone via a stainless steel mesh belt system. There, the material is heated to 350°C, using natural gas heating and waste gas combustion to ensure uniform heating, preparing for the pyrolysis stage. Next, the material is conveyed to the pyrolysis zone, where high-power microwaves at 915MHz and 2450MHz provide instantaneous heating, achieving efficient and uniform pyrolysis. At this point, the fibers in the material begin to separate from the resin on the surface, producing pyrolysis gases.

[0043] During the cracking process, the waste gas first passes through a magnetized ionization device to ionize the gas. This process purifies the cracked gas, facilitating subsequent energy recovery. The ionized gas is then burned with natural gas, and the released heat is effectively recovered in the preheating area, forming a highly efficient heat cycle system that maximizes energy utilization throughout the entire process.

[0044] After pyrolysis and cracking, the product enters a cooling phase. A cooling system is designed to effectively remove residual heat, ensuring a stable and safe material temperature. The cooled product then undergoes physical processing, ultimately yielding high-quality carbon fiber. This process not only achieves efficient material conversion and heat recovery, but also enhances resource utilization.

[0045] refer to Figure 14The heating process in the microwave output cabinet 107 begins with the magnetron generating high-frequency microwaves, which are evenly transmitted into the incinerator 101. When the material is exposed to the microwaves, the water molecules within it absorb the microwave energy, rapidly vibrating and converting it into heat, rapidly heating the material. Because microwaves penetrate the material, achieving uniform heating, this effectively improves heating efficiency and reduces thermal stress. After heating is complete, the material reaches the preset processing temperature and is then cooled and processed.

[0046] Example 2

[0047] Reference Figures 2 to 13 , which is a second embodiment of the present invention. In order to treat the exhaust gas generated after the above-mentioned pyrolysis, a detection component 200 is set in the device, including an exhaust pipe 201 connected to the incinerator 101, a spray tower 202 connected to the exhaust pipe 201, a treatment chamber 203 connected to the spray tower 202, a detector 204 and an exhaust fan 205 arranged in the treatment chamber 203, a driving box 206 arranged outside the treatment chamber 203, a first sprocket 207 and a second sprocket 208 symmetrically rotated in the driving box 206, a chain 209 engaged with the first sprocket 207 and the second sprocket 208, a driving rod 210 connecting the exhaust fan 205 and the first sprocket 207, a fixed block 211 set on the chain 209, a slider 212 slidably connected to the driving box 206, and a sliding frame 213 and a connecting rod 214 fixed on the slider 212. The spray tower 202 is a desulfurization and dust removal spray tower. The bottom of the treatment chamber 203 is connected to a smoke inlet pipe 203a, and the top of the treatment chamber 203 is connected to a chimney 203b. A detector 204 is installed at the outlet of the smoke inlet pipe 203a to monitor exhaust gas indicators. An exhaust fan 205 is installed in the treatment chamber 203, and the inner wall of the treatment chamber 203 is also provided with a spiral guide groove 203c. The rotating shaft of the exhaust fan 205 is fixedly connected to one end of a drive rod 210, and the other end of the drive rod 210 is fixedly connected to the rotating shaft of the first sprocket 207. A slide groove 206a is defined on the inner wall of the drive box 206, and a slider 212 is inserted into the slide groove 206a. The slide groove 206a is horizontally arranged, and the sliding frame 213 is rectangular and vertically fixed to the slider 212. The fixed block 211 is rotatably mounted on the chain 209 and inserted into the sliding frame 213. The connecting rod 214 is fixed on the side wall of the slider 212 . The connecting rod 214 extends outside the drive box 206 . The end of the connecting rod 214 is fixedly connected to the end of the piston 308 .

[0048] Through the above scheme, reference Figures 2 to 11The waste gas is discharged from the incinerator 101 through the exhaust pipe 201 to the spray tower 202, 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 set at the outlet of the smoke inlet pipe 203a to monitor harmful substances. After detecting that the harmful substances exceed the standard, the host computer starts the exhaust fan 205 to start rotating. The detector 204 sends an electrical signal to the host computer and controls the exhaust fan 205 to start. This is a conventional technical means and will not be repeated here. The exhaust fan 205 can adjust the speed and wind force according to the size of the waste gas index. In order to adjust the amount of catalyst input according to the rotation speed of the exhaust fan 205, a driving rod 210 is fixed on the exhaust fan 205. 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. A fixed block 211 is fixed on the chain 209. The fixed block 211 can be approximately considered to be fixed at a point on the chain 209. The fixed block 211 moves in a circular path with the chain 209. 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 vertical setting The sliding frame 213 of the fixed block 211 is configured so that only the left and right movement of the fixed block 211 will exert force on the sliding frame 213, that is, the fixed block 211 drives the sliding frame 213 to move horizontally when it moves with the chain 209, and the sliding frame 213 is fixed to the slider 212. The sliding frame 213 can make the slider 212 move horizontally left and right in the slide groove 206a, driving the connecting rod 214 on the slider 212 to extend into and out of the drive box 206, and converting the rotational force of the exhaust fan 205 into the horizontal movement of the connecting rod 214, and the extension and retraction frequency of the connecting rod 214 can be adjusted according to the rotational speed of the exhaust fan 205.

[0049] To add catalyst to the process chamber 203, refer to Figures 12 and 13The device includes a purification assembly 300, which includes a purification chamber 301, a liquid inlet pipe 302 and a liquid outlet pipe 303 disposed at the front and rear ends of the purification chamber 301, the liquid inlet pipe 302 connected to a liquid storage tank 304, the liquid outlet pipe 303 connected to a nozzle 305 in the treatment chamber 203, a transfer chamber 306 disposed within the purification chamber 301, a connecting chamber 307 connecting the transfer chamber 306 and the liquid inlet pipe 302, a piston 308 fixedly connected to the connecting rod 214, a channel 309 disposed in the center of the piston 308, a through hole 310 disposed in the rod of the piston 308, and a movable member 311 disposed between the channel 309 and the liquid inlet pipe 302. The movable member 311 includes a ball 312 and a spring 313. The liquid storage tank 304 supplies catalyst to the purification chamber 301 via the liquid inlet pipe 302, and the liquid outlet pipe 303 is connected to the transfer chamber 306. A piston 308 slides within the transfer chamber 306. The radial diameter of the piston 308's rod is smaller than the radial diameter of the piston's end. A channel 309 extends inward from the top of the piston 308 and is generally cylindrical. The channel 309 at the piston's end is narrower than the channel 309 at the piston's rod. Several through-holes 310 are evenly distributed along the sidewall of the piston's rod. Two movable members 311 are provided: one at the piston's rod and the other at the opening of the liquid inlet pipe 302 within the purification chamber 301. In the movable part 311 located in the channel 309, the blocking ball 312 is in the channel 309 of the rod of the piston 308, the radial diameter of the blocking ball 312 is larger than the radial diameter of the channel 309 at the end of the piston 308, one end of the spring 313 is connected to the blocking ball 312, and the other end is connected to the inner wall of the channel 309; in the movable part 311 located at the liquid inlet pipe 302, the blocking ball 312 is at the pipe mouth of the liquid inlet pipe 302, the radial diameter of the blocking 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 to the blocking ball 312, and the other end is connected to the inner wall of the purification chamber 301, and the springs 313 in the two movable parts 311 are both in a compressed state in their natural state.

[0050] By the above scheme, the piston 308 is fixedly connected to the connecting rod 214, and the expansion and contraction of the connecting rod 214 is also the expansion and contraction of the piston 308 in the transfer chamber 306. In the natural state, the catalyst in the liquid storage tank 304 flows into the liquid inlet pipe 302, and the blocking ball 312 in the liquid inlet pipe 302 and the channel 309 closes the pipeline, and the catalyst cannot flow normally. The piston 308 expands and contracts in the transfer chamber 306. When the piston 308 extends toward the liquid inlet pipe 302, the piston 308 approaches the connecting chamber 307, and the two blocking balls 312 are closed. The space between the balls 312, that is, between the connecting chamber 307 and the channel 309 at the end of the piston 308, becomes smaller and smaller, the internal air pressure increases, and the catalyst is discharged outward, so that the blocking ball 312 at the mouth of the liquid inlet pipe 302 is stuck at the mouth of the pipe, and this place is still in a closed state, while the blocking ball 312 located in the channel 309 will be pushed open, squeezing the spring 313 connected to it, and the catalyst between the two blocking balls 312 will be discharged from the through hole 310 to the transfer chamber 306, and move along the liquid outlet pipe 303 until it is ejected from the nozzle 305. 309 ; when the piston 308 moves away from the liquid inlet pipe 302 and contracts in the transfer chamber 306, the space between the two blocking balls 312 becomes larger and the air pressure becomes smaller. The relative air pressure outside the two blocking balls 312, that is, the relative air pressure inside the liquid inlet pipe 302 and the transfer chamber 306 is large, will apply force to the two blocking balls 312, and the blocking ball 312 located in the channel 309 will be pressed against the channel opening 309, closing the road in the channel 309, while the blocking ball 312 at the opening of the liquid inlet pipe 302 will be pushed open and squeeze the spring 31 below it. 3. The catalyst in the liquid inlet pipe 302 is sucked into the connecting chamber 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; 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 drives the piston 308 to extend and retract, the catalyst in the liquid storage tank 304 can be continuously extracted and discharged into the treatment chamber 203. Figure 13 In the direction of the middle arrow, this process can also be accelerated according to the expansion and contraction frequency of the piston 308, that is, the rotation speed of the exhaust fan 205. The higher the exhaust gas index, the faster the rotation speed of the exhaust fan 205, and the faster the catalyst in the nozzle 305 can be ejected. The exhaust gas enters the treatment chamber 203 through the smoke inlet pipe 203a and is finally discharged from the chimney 203b connected to the top. When harmful substances are detected, the exhaust fan 205 blows air to the vertically rising exhaust gas from the side to disturb the exhaust gas flow and fully mix it with the catalyst to improve the catalytic efficiency. It also causes the exhaust gas to move along the inner wall toward the spiral guide groove 203c, forming a turbine to accelerate the discharge of the chimney 203b.
