[0109] When the present embodiment is in use, first, the push rods of all the clamping oil cylinders 33 are pushed so that all the hooks 34 are opened, and the door body 30 can be opened. Then, all the inner material discharging boxes 100 that need to be processed are moved to the left along the guide wheel 1003 on the corresponding guide rail 21, and all the inner material discharging boxes 100 are placed in the inner box body 20. The left side plate of the leftmost inner material discharging box 100 is pressed against the right end surface of the left end plate 11.

[0110] Then, the control valve connected to the gas outlet of the nitrogen tank 80 is opened, and the control valve on the nitrogen inlet pipe 6 is opened, and the nitrogen enters the carbonization box 1000 from the gas inlet end of the nitrogen inlet pipe 6, and the gas in the inner box 20 of the carbonization box 1000 is discharged. Generally, the gas is inflated for a certain time (such as about 10 minutes), and then, after the door body 30 is closed, the push rods of all the pressing cylinders 33 will shrink, so that the hook 34 will flip back to its original position, and the door body 30 and the right door frame 12 are connected and fixed; at this time, the inner box 20 and the connected pipelines are filled with nitrogen, and then, the control valve connected to the gas outlet of the nitrogen tank 80 is closed, and the control valve on the nitrogen inlet pipe 6 is closed;

[0111] Then, the thermal energy furnace 200 is turned on, and the blower connected to its return air port is turned on to realize the circulation of nitrogen. Since the present application has two carbonization boxes 1000, the control valve at the first main connecting pipe 201 and the first main air inlet pipe 161 of the rear carbonization box 1000 is closed, and the control valve connecting the second main connecting pipe 202 and the air outlet end of the main air outlet pipe 13 of the rear carbonization box 1000 is closed, that is, the thermal energy furnace 200 at this time provides heat energy for the front carbonization box 1000.

[0112] It is heated by the thermal energy furnace 200, and the high-temperature nitrogen enters into the left cover body 16 from the first main air inlet pipe 161, and then enters into all the middle ventilation connecting pipes 1001, and then is discharged from the corresponding side air outlet holes and ends. The gas discharged from the side air outlet holes is blown onto the materials placed on the middle ventilation connecting pipe 1001 and the air guide pipe 1002, providing heat for heating, drying and carbonizing the materials. Then, part of it is discharged from the flow holes and the top of the inner discharge box 100, and part of it enters from the side air inlet holes of the air guide pipe 1002, and then is discharged from both ends of the air guide pipe 1002, thereby increasing the flow time of the hot air in the inner discharge box 100. Moreover, since the air guide pipe 1002 and the middle ventilation connecting pipe 1001 are staggered, the materials thereon are heated uniformly, thereby improving the uniformity of the carbonization and the effect.

[0113] During the heating process, nitrogen is passed through the spiral channel 1, and a control valve (which is a conventional structure and is omitted in the drawings) is connected to the top of the exhaust pipe 15. When it is closed, the blowing device stops running to ensure that the nitrogen in the spiral channel 1 does not flow. Of course, a control valve can be connected to the air outlet of the blowing device to communicate with the cooling air inlet pipe 14. When not in use, the control valve is closed (the control valve is not installed in this embodiment); when flushing nitrogen, nitrogen is introduced through the top of the exhaust pipe 15 (a connecting pipe on the nitrogen tank is connected to the control valve at the top of the exhaust pipe 15). When introducing nitrogen, the blowing device stops running. After the addition is completed, the control valve at the top of the exhaust pipe 15 is closed and the connected connecting pipe can be pulled out.

[0114] Then, the hot air in the inner box 20 flows back to the lower extension sleeve 131 from the side return air hole of the lower extension sleeve 131, and then flows into the main outlet pipe 13, and then flows from the main outlet pipe 13 to the first ash remover 300. After ash removal by the first ash remover 300, it returns from the first return air pipe 301 to the air inlet of the blower connected to the return air port of the thermal energy furnace 200, realizing a circulating flow, and then realizes circulating heating through the thermal energy furnace 200 to provide heat energy for the inner box 20; the bottom of the discharge control valve 67 at the bottom of the first ash remover 300 can be connected to a dust collection device such as a cloth bag to collect dust for treatment. This is a conventional structure and will not be described in detail here.

[0115] During this process, the control valve of the air intake pipe 600 is opened and closed at a fixed time, and oxygen is added to the inner box 20 at a fixed time and in a fixed quantity, so that the material can be burned fully.

[0116] After being heated to a certain temperature, such as 150° (the temperature is sensed by the temperature sensor 3 and the data is transmitted to the control host), the control valves provided at the main air outlet pipe 13 and the first main air inlet pipe 161 of the carbonization box 1000 at the front are closed, and the control valves provided at the main air outlet pipe 13 and the first main air inlet pipe 161 of the carbonization box 1000 at the rear are opened, so that the thermal energy furnace 200 provides heat for the carbonization box 1000 at the rear, and the remaining operations are the same as the heating process of the carbonization box 1000 at the front;

[0117] At this time, the control valve at the air inlet of the first circulation outlet pipe 17 of the front carbonization box 1000 is opened, and the control valve at the first circulation air inlet pipe 162 is opened. At the same time, the control valve of the air inlet pipe 600 continues to open and close regularly to quantitatively introduce oxygen into the left cover body 16, thereby providing oxygen to the inner box 20, so that the materials inside it are fully burned and carbonized. During the combustion process, the circulation fan 61 is operated to allow the hot air in the inner box 20 to enter the dust collector 60, and then enter the condenser 40 after dust removal. At this time, the cooling water in the condenser 40 does not flow, so the gas is not condensed, and then returns to the inner box 20 for combustion. When its temperature reaches 450°, the control valve of the air inlet pipe 600 is closed, oxygen stops being added, and the gas continues to flow;

[0118] During the entire heating process or gas circulation process, when the pressure is too high (when it exceeds 2 kPa, it is sensed by the pressure sensor 4), at this time, it is necessary to open the control valve on the connecting pipe connecting the outlet end of the cooling gas outlet pipe 432 of the condenser 40 and the air inlet connector of the negative pressure tank 50. At the same time, the cooling water in the condenser 40 flows. At this time, after the gas passes through the condenser 40, the gas temperature will be greatly reduced, and the water, oil and other substances in the hot gas will be discharged, and part of the gas discharged from the condenser 40 will enter the negative pressure tank 50 from the cooling gas outlet pipe 432 to be stored, thereby reducing the pressure of the inner box 20. When the pressure is less than 2 kPa, the control valve on the connecting pipe connecting the outlet end of the cooling gas outlet pipe 432 and the air inlet connector of the negative pressure tank 50 is closed. At this time, the control valve on the second branch exhaust pipe 57 is opened, and the second vacuum pump 59 is running, thereby sucking the gas absorbed in the negative pressure tank 50 into the first exhaust gas storage In the gas tank 700, when the first waste gas storage tank 700 is full, it will flow into the second waste gas storage tank 800. When the second waste gas storage tank 800 is full, the control valve on the connecting pipe connected to the gas connecting pipe of the thermal energy furnace 200 can be opened, so that the inhaled gas enters the gas connecting pipe of the energy furnace 200 and is used as an auxiliary fuel (the gas absorbed by the negative pressure tank 700 is the gas of material combustion, which contains a large amount of organic matter and other substances that can be used as auxiliary fuel), and also reduces emissions. At the same time, the operation of the second vacuum pump 59 can keep the negative pressure tank 50 in a negative pressure state. After running for a certain period of time, the second vacuum pump 59 stops running, the control valve on the connecting pipe connected to the gas connecting pipe of the thermal energy furnace 200 is closed, the control valve on the second branch exhaust pipe 57 is closed, and the control valve on the connecting pipe where the outlet end of the cooling gas outlet pipe 432 is connected to the air inlet connector of the negative pressure tank 50 is opened to continue to adsorb excess gas.

[0119] After running at 450° for a certain period of time, carbonization is basically completed, and the control valve at the second connecting pipe is opened, so that the carbon dioxide in the exhaust connector 401 of the carbon dioxide storage tank 400 can enter the corresponding first main air intake pipe 161, and then enter the inner box body 20). At the same time, steam is introduced into the steam intake pipe 5 (the steam is opened by the second angle seat valve of the corresponding fourth connecting pipe of the steam tank 500, and steam can be added to the steam intake pipe 5). The steam first enters the annular pipe 1631, and then is discharged from the multiple steam distribution holes on the extension pipe 1632 and enters the inner box body 20. Together with the carbon dioxide, the material in the inner discharge box 100 is activated. After a certain period of time, the activation is completed, and then the addition of steam and carbon dioxide is stopped.

[0120] Then, the temperature is lowered. When lowering the temperature, the control valve connected to the top of the exhaust pipe 15 is opened, the blowing device is turned on, the external gas is passed into the spiral channel 1, the nitrogen inside is discharged, and the main box body 10 and the inner box body 20 are quickly cooled. At this time, the control valves arranged at the main outlet pipe 13 and the first main air inlet pipe 161 are still closed. At the same time, the control valve at the air inlet of the first circulation outlet pipe 17 is still opened, the control valve at the first circulation air inlet pipe 162 is opened, and the circulation fan 61 is operated, so that the hot air in the inner box body 20 enters the dust collector 60, and after dust removal, enters the condenser 40 for condensation. At this time, the condenser 4 0 is still flowing, thereby continuing to cool the gas and materials in the inner box body 20 until the temperature drops to about 80°, then the door body 30 can be opened, and then the door cover 165 can be opened, the pin 181 can be pulled out, and the two locking nuts can be removed. Then, the transverse connecting shaft 48 can be pulled out to the left from the disassembly through-tube 164 (it is necessary to use a manipulator or a clamp to extend into the disassembly through-tube 164, and its end is screwed to the screwed portion at the left end of the transverse connecting shaft 48, and the transverse connecting shaft 48 can be pulled out by pulling outward). At this time, all the inner discharge boxes 100 can be removed from the inner box body 20. It is easy to operate and has a good use effect.

[0121] After one carbonization box 1000 is completed, the other carbonization box 1000 at the rear is operated in the same way. When the two carbonization boxes 1000 do not need the heat provided by the thermal energy furnace 200, the thermal energy furnace 200 can reduce the combustion volume, but it is still necessary to ensure that it is in a combustion state. Because, during the heating process from 150° to 450°, when the temperature in the carbonization box 1000 cannot be heated up any further, the corresponding two control valves need to be opened so that the gas in the inner box 20 of the corresponding carbonization box 1000 passes through the thermal energy furnace 200 again to achieve heating to increase its temperature. After running for a certain period of time, the corresponding two control valves are closed to achieve self-circulation of the carbonization box 1000 and the corresponding condenser 40 and dust collector 60 to continue heating.

[0122] In this embodiment, when the condenser 40 is in use, the first heat exchange water outlet connecting pipe 4112 is connected to the water return pipe, and the first heat exchange water inlet connecting pipe 4121 is connected to the cooling water outlet pipe, and the cooling water outlet pipe and the water return pipe are connected to a water-cooled chiller (which is a conventional structure and can be purchased directly, and will not be described in detail here), and the sum of the cross-sectional areas of the inner flow cavities of all inner tube bodies 414 is greater than or equal to the cross-sectional area of ​​the inner flow cavities of the total air outlet connecting pipe head 431 or the total air inlet connecting pipe head 421, and the cross-sectional areas of the inner flow cavities of the total air outlet connecting pipe head 431 and the total air inlet connecting pipe head 421 are equal.

[0123] The hot air from the furnace body enters from the main air inlet connecting pipe head 421, reaches the bottom air inlet shell 420, and then enters all the inner tube bodies 414. The cooling water enters the lower shell 412 from the first heat exchange water inlet connecting pipe 4121, and then enters the outer tube body 413, so that the gas in the inner tube body 414 and the water in the outer tube body 413 exchange heat, thereby cooling the gas. The cooled gas enters the upper air outlet shell 430, and then is discharged from the main air outlet connecting pipe head 431 and enters the inner box body 20.

[0124] The water after heat exchange enters the upper shell 411 and then flows out from the first heat exchange water outlet connecting pipe 4112;

[0125] Some water droplets or oil will be formed in the cooled gas, which will fall along the inner tube body 414 and enter the lower cylindrical body 422 from the lower part of the bottom air inlet shell 420. The liquid level in the lower cylindrical body 422 can be checked by the liquid level gauge 425. When the liquid exceeds the sensing end of the liquid level sensor 426 (the liquid level sensor 426 in this embodiment is a photoelectric liquid level sensor, which uses the principle of reflection and refraction of light at the interface of two different media to achieve sensing), the liquid is sensed by the sensing end of the liquid level sensor 426. When it senses the liquid, the control host receives the signal transmitted by the liquid level sensor 426 and processes it, and then opens the first solenoid valve at the oil outlet pipe 424 until the liquid level sensor 426 is filled. When liquid is sensed, the first solenoid valve at the oil outlet pipe 424 is closed, and then the control host controls the first solenoid valve at the liquid outlet connecting pipe 423 to open, so that water can flow out from the liquid outlet connecting pipe 423. It is usually opened for about 60 seconds. The liquid level gauge 425 is also manually observed. According to the decrease in the liquid level of the liquid level gauge 425, the first solenoid valve at the liquid outlet connecting pipe 423 is manually closed. The oil and part of the water above the sensing end of the liquid level sensor 426 can be discharged from the oil outlet pipe 424 (usually it is oil, and occasionally there will be part of water, but it will not affect the discharge); the rest of the water is discharged from the liquid outlet connecting pipe 423 (a small amount of oil may occasionally be mixed in the liquid outlet connecting pipe 423, but it will not affect the discharge).

[0126] The liquid discharged from the liquid outlet connecting pipe 423 and the oil outlet pipe 424 can be subsequently processed and reused.

[0127] It can automatically discharge the water and oil generated by cooling in real time, reduce accumulation, ensure the normal operation of the equipment, and have a good use effect. Among them, the oil outlet pipe 424 and the liquid outlet connecting pipe 423 can be connected to the discharge tank to store the discharged liquid.

[0128] When the dust collector 60 of this embodiment is in use, after the hot air enters from the right air inlet connector 63, it is blocked by multiple middle partitions 621 to increase the circulation time in the dust collector 60 (wherein, multiple through holes are formed on the middle partition 621, so as to ensure that the hot air can flow out from the through holes and achieve guidance), and then, after being filtered by the filter screens of all the filter screens 66 with gradually increasing mesh numbers, the dust particles of corresponding sizes can fall into the corresponding dust collection cylinder 65, and the discharge control valve 67 at the bottom thereof is opened, so that the dust can fall into the discharge control valve 67 at the bottom thereof. The storage bag is a conventional structure and will not be described in detail here. Before the dust is discharged from the discharge control valve 67, it passes through the cooling ring assembly 66. One end of the two water-passing connectors of the cooling ring assembly 66 is connected to the water inlet pipe and the other end is connected to the water outlet pipe (the water inlet pipe and the water outlet pipe are connected to a water-cooled chiller, which is a conventional structure and can be directly purchased and will not be described in detail here), so that cooling water passes through the cooling ring assembly 66, and the dust passing through the cooling ring assembly 66 is cooled to ensure that the temperature of the dust entering the storage bag is not high, and the safety is high.

[0129] At the same time, when in use, the timed vibration of the vibration motor 68 can prevent dust accumulation in the dust collection tube 65 and ensure normal material dropping. At the same time, the vibration is transmitted to the dust removal main box 62, and the corresponding filter screen plate 66 can also be vibrated, so that the accumulated dust placed thereon will not fall off, thereby improving the dust removal effect.

[0130] In this embodiment, the first vacuum pump 58 is used when the negative pressure tank 50 is repaired and maintained or is shut down. The control valve of the first sub-exhaust pipe 56 needs to be opened, and the first vacuum pump 58 is turned on to achieve air extraction, so as to discharge the gas in the negative pressure tank 50 and achieve negative pressure to ensure that there is no other gas inside. Then, the control valve of the first sub-exhaust pipe 56 is closed to complete the air extraction. This operation is to prevent the negative pressure tank 50 from mixing with the subsequent gas during subsequent use due to the mixture of air and combustion or even explosion, thereby improving the safety protection effect.
