[0024] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0025] like Figures 1 to 3 As shown, a recycling and reuse device based on carbonization cracking includes:

[0026] Two carbonization cracking furnaces 1 are arranged up and down, and the carbonization cracking furnace 1 includes a combustion heating component, a base 12, a furnace barrel 13 and a rotating driving component 14. The furnace barrel 13 is rotatably connected to the base 12, and the rotating driving component 14 is connected to the furnace barrel 13 to drive the furnace barrel 13 to rotate. A furnace cavity with a shovel plate on the inner wall is provided in the furnace barrel 13, and the combustion heating component is suitable for heating the furnace cavity. One end of the furnace barrel 13 is provided with a feed port 13a connected to the furnace cavity, and the other end of the furnace barrel 13 is provided with a feed port 13a connected to the furnace cavity. The discharge port 13b is provided with a feed device corresponding to the feed port 13a, and a discharge device is provided corresponding to the discharge port 13b. When the furnace drum 13 rotates, it is suitable for conveying the material in the furnace cavity from the feed port end to the discharge port end. The discharge ports 13b and the corresponding discharge devices of the upper and lower carbonization cracking furnaces 1 are staggered, and in adjacent carbonization cracking furnaces 1, the discharge device of one carbonization cracking furnace 1 is connected to the feed device of another carbonization cracking furnace 1 to introduce materials;

[0027] The cooling furnace 2 is located below the carbonization and cracking furnace 1 at the lowest end, and an inlet is provided at one end of the cooling furnace 2, and an outlet is provided at the other end of the cooling furnace 2. A material conveying component for conveying materials from the inlet end to the outlet end is provided in the cooling furnace 2, and the inlet of the cooling furnace 2 is connected to the discharge device of the carbonization and cracking furnace 1 at the lowest end.

[0028] In this embodiment, the rotating drive component 14 can be the following structure, including a ring gear installed outside the furnace drum 13, a gear meshing with the ring gear, and a driving component connected to the gear and driving the gear to rotate. The driving component can specifically be a transmission mechanism + motor. A rotating support wheel can be set on the base 12, and the furnace drum 13 is supported on the support wheel to achieve a rotating connection between the furnace drum 13 and the base 12. The rotating drive component 14 can also be other existing structures, which will not be described in detail in this embodiment.

[0029] Specifically, in order to reasonably utilize heat, a jacket 15 is provided outside the furnace barrel 13. The combustion and heat supply component is suitable for heating the jacket 15 and transferring heat to the furnace chamber through the jacket 15. The jackets 15 of adjacent carbonization and cracking furnaces 1 are connected through channel pipes 15a.

[0030] In this embodiment, if Figure 2 As shown, the combustion and heating components are multiple natural gas nozzles 11 arranged on the periphery of the carbonization cracking furnace 1, and the natural gas nozzles 11 partially extend into its jacket 15. The natural gas can come from the natural gas collected by the subsequent tail gas collection and processing components, and of course it can also come from commercially available natural gas.

[0031] Specifically, in order to avoid pollution caused by the discharged gas, the recycling and reuse equipment based on carbonization cracking also includes a jacket 15 tail gas emission treatment component, which is connected to the tail gas emission port of the jacket 15 of the uppermost carbonization cracking furnace 1. The jacket 15 tail gas emission treatment component includes a water cooler 32, an induced draft fan 33 and an exhaust pipe 34 connected in sequence. The tail gas after combustion in the carbonization cracking furnace 1 is led to the exhaust pipe 34 through the induced draft fan 33 in the jacket 15 for discharge. A water cooler 32 can be installed in front of the induced draft fan 33 for cooling. Whether a denitration device 31 is installed before the water cooler 32 depends on environmental protection requirements.

[0032] Specifically, in the present embodiment, there are two carbonization cracking furnaces 1 arranged in an upper and lower manner; thus, the feeding device of the uppermost carbonization cracking furnace 1 includes a screw conveyor, which is suitable for conveying materials forward to the feeding port 13a of the furnace drum 13, and the discharging device of the uppermost carbonization cracking furnace 1 includes a discharging pipe 41, which is rotatably connected to the corresponding discharging port 13b; the feeding device of the lowermost carbonization cracking furnace 1 includes a feeding pipe 42; the discharging device of the lowermost carbonization cracking furnace 1 includes a rotary discharger 44; of course, in some embodiments, when there are more than three carbonization cracking furnaces 1 arranged in an upper and lower manner, except for the uppermost and Outside the carbonization and cracking furnace 1 at the lowermost end, the feeding device of the middle carbonization and cracking furnace 1 includes a feeding pipe 42, and the discharging device of the middle carbonization and cracking furnace 1 includes a discharging pipe 41; in adjacent carbonization and cracking furnaces 1, the discharging pipe 41 of the upper carbonization and cracking furnace 1 is connected to the feeding pipe 42 of the lower carbonization and cracking furnace 1 through a bellows 43 to introduce materials; wherein, the feeding pipe 42 and the corresponding feeding port 13a can be rotatably connected through a rotating joint, the discharging pipe 41 and the corresponding discharging port 13b can be rotatably connected through a rotating joint, and the rotary discharger 44 and the corresponding discharging port 13b can also be rotatably connected through a rotating joint.

[0033] Specifically, the recycling and reuse equipment based on carbonization and cracking also includes a feeding component, which is arranged corresponding to the feeding device of the uppermost carbonization and cracking furnace 1, and the feeding device transports the material coming out of the feeding component to the feeding port 13a of the furnace drum 13.

[0034] Specifically, in order to minimize the amount of oxygen brought into the material when it enters the furnace, the feeding component includes a first hopper 51 and a second hopper 52. The first hopper 51 is provided with a first material inlet and a first material outlet suitable for opening or closing, and the second hopper 52 is provided with a second material inlet and a second material outlet suitable for opening or closing. The first material outlet is connected to the second material inlet. When the first material inlet is opened, the second material inlet is closed; when the first material inlet is closed, the second material inlet is suitable for opening.

[0035] Specifically, in order to ensure that the materials entering the furnace are carbonized and cracked in an oxygen-free condition, the second hopper 52 is provided with an air outlet 53 and an air inlet 54 which are suitable for opening or closing. Gas is rushed into the materials in the second hopper 52 from the air inlet 54 before entering the furnace, and the air outlet 53 is opened until no gas is discharged from the air outlet 53, and then the air inlet 54 and the air outlet 53 are closed to ensure that the materials entering the furnace are in an oxygen-free condition.

[0036] In this embodiment, the raw material is torn into small pieces of about 1.5 cm by a shredder and is put into the first hopper 51 through an elevator, and then goes down to the second hopper 52. When entering the first hopper 51, the second material inlet of the second hopper 52 is closed. When there is no material in the second hopper 52, the second material inlet of the second hopper 52 is opened and the first material inlet of the first hopper 51 is closed. In this way, the oxygen brought into the material when entering the furnace is reduced as much as possible. Before the material in the second hopper 52 enters the furnace, nitrogen is flushed into the air inlet 54 from the air inlet 54, and the air outlet 53 is opened to ensure that there is no air and only nitrogen at the air outlet 53. Then, the air outlet 53 and the air inlet 54 are closed, and then the screw conveyor is turned on to allow the material in the second hopper 52 to slowly enter the furnace. This operation ensures that the materials entering the furnace are carbonized and cracked under oxygen-free conditions.

[0037] Specifically, in order to process the material after carbonization and cracking to obtain the required recycled material, the recycling and reuse equipment based on carbonization and cracking also includes a material post-processing component, which includes an eddy current separator 62 and a vibrating screen 63 for correspondingly processing the material coming out of the outlet of the cooling furnace 2; of course, a belt conveyor 61 can be set between the outlet of the cooling furnace 2 and the eddy current separator 62, and the material screened by the vibrating screen 63 can be transported out through another belt conveyor 61.

[0038] In this embodiment, due to the diversity of raw materials, two-stage carbonization cracking furnaces 1 are selected and placed up and down. The furnace drum 13 of the carbonization cracking furnace 1 is made of stainless steel 310S. The internal rotating shaft is driven by a motor to slowly rotate. The rotation speed can be adjusted to a suitable speed by adjusting the motor frequency. The natural gas nozzle 11 is jet-burned below the carbonization cracking furnace 1. The furnace drum 13 and the base 12 are made of refractory bricks for fireproofing and heat preservation. No transmission device is set between the two carbonization cracking furnaces 1. The material falls naturally from the discharge device of the upper carbonization cracking furnace 1 to the feeding device of the next carbonization cracking furnace 1 by gravity. The hot gas generated by the combustion of natural gas below the lower carbonization cracking furnace 1 enters the jacket 15 of the upper carbonization cracking furnace 1 through its jacket 15 for heating. According to the furnace temperature display of the upper carbonization cracking furnace 1, several natural gas nozzles 11 corresponding to the upper carbonization cracking furnace 1 are appropriately opened as required to make the temperature reach the requirement.

[0039] In addition, in this embodiment, the types and contents of resins contained in the raw materials are different, some have long carbonization and cracking time and some have short carbonization and cracking time, and they are made into two-stage type, which can meet the requirements of long-term carbonization and cracking. The short carbonization and cracking time can increase the motor speed and increase the output without affecting the production. The carbonization time of the carbonization and cracking furnace 1 is generally controlled to be 1-4 hours, and the temperature control is generally controlled between 500-900. After the carbonization and cracking is completed, the material falls into the cooling furnace 2 for cooling, and the material is discharged when the temperature is cooled to below 50 degrees. A rotating rotor (i.e., a rotating discharger 44) is used between the bottom carbonization and cracking furnace 1 and the cooling furnace 2 to ensure that only material is transported but not ventilated between the bottom carbonization and cracking furnace 1 and the cooling furnace 2, and the cooling The materials discharged from furnace 2 are directly passed through an eddy current separator 62 to separate conductive metals from non-conductive non-metals. The non-metals are separated from bulk glass fiber cloth and powdered carbon powder and silicon dioxide powder through a vibrating screen 63. The powdered carbon powder and silicon dioxide powder can be sent to a cement plant to replace clay and coal, and can also be used to make bricks. The bulk glass fiber cloth and thermosetting resin are mixed in a certain ratio and then put into a hot press to be hot-pressed to form glass fiber composite products for sale. A small amount of carbon powder and silicon dioxide powder can also be added to the glass fiber cloth and resin for hot-pressing. If the waste fiberglass products do not contain metal parts, the eddy current separator 62 is not required in the processing flow, and the glass fiber cloth, carbon powder and silicon dioxide powder are directly put into the vibrating screen 63 to be sorted out.

[0040] Specifically, in order to recycle the generated gas, the recycling and reuse equipment based on carbonization cracking also includes a tail gas collection and processing component, which includes a tail gas heating furnace 71, a spray tank 72, a vortex pump 74 and a buffer tank 75 connected in sequence. The tail gas heating furnace 71 is connected to the tail gas collection port of the carbonization cracking furnace 1; of course, multiple condensers 73 can be connected between the spray tank 72 and the vortex pump 74 for condensation treatment. The gas generated by the carbonization cracking of the resin in the furnace is treated by the tail gas heating furnace 71; wherein, the tail gas heating temperature is controlled between 750-800 degrees, and the heating is heated by the jet combustion of the jacket 15 natural gas nozzle 11. In the tail gas heating furnace 71, the multi-carbon structure tar in the tail gas is converted into single-carbon methane gas, and the generation of dioxins is also eliminated. Then, the absorption tower containing bromine atoms and sulfur adsorbents can be used for adsorption. The gas passes through the spray tank 72, dust removal and cooling into clean and qualified natural gas, and enters the buffer tank 75 for standby after being pressurized by the vortex pump 74.

[0041] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
