Description

Technical Field

[0001] This invention relates to the field of carbonization processing equipment technology, and more specifically to a carbonization system. Background Technology

[0002] Carbonization, also known as dry distillation, carbonization, or coking, refers to the reaction process of heating and decomposing solid or organic matter under air-isolated conditions, or a method of heating solid substances to produce liquid or gaseous products (usually turning them into solids).

[0003] Existing carbonization processes, such as carbonization of wood or bamboo, typically involve carbonization furnaces or boxes. These furnaces require heat from a thermal furnace, which is usually set up one-to-one, resulting in low utilization. Furthermore, the exhaust gas from these furnaces is directly emitted without recycling, limiting their effectiveness and energy conservation. Additionally, the water vapor and nitrogen dioxide required for subsequent activation in the carbonization box are supplied by other equipment, leading to high costs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a carbonization system that can provide heat for multiple carbonization chambers from a single thermal furnace, resulting in high utilization. Furthermore, the carbon dioxide waste gas generated by the thermal furnace and the steam generated by the bottom steam cylinder can be used for carbonization of materials in the carbonization chambers, thereby improving utilization, greatly reducing production costs, and achieving good results.

[0049] For example, see below. Figures 1 to 27 As shown ( Figure 1 Components such as the air intake pipe and nitrogen intake pipe are omitted and not shown. Figure 19 (The outer annular sleeve 662 and other components of one of the cooling ring components 66 are omitted). A carbonization system includes a thermal furnace 200 (which can be an existing common thermal furnace, or a structure similar to that of a high-efficiency hot air device with precise oxygen distribution in a pipe and two-stage catalytic combustion disclosed in Chinese patent application No. 202110193078.X, which will not be described in detail here) and at least one carbonization box 1000. The circulating hot gas outlet of the thermal furnace 200 is connected to a first main connecting pipe 201, and one outlet of the first main connecting pipe 201 is connected to a control valve. The first main air inlet pipe 161 of the carbonization box 1000 is connected to the main air outlet pipe 13 of the carbonization box 1000. The air outlet of the main air outlet pipe 13 of the carbonization box 1000 is connected to an air inlet of the second main connecting pipe 202 through a control valve. The air outlet of the second main connecting pipe 202 is connected to the air inlet of the first ash remover 300. The air outlet of the first ash remover 300 is connected to one end of the first return air pipe 301. The other end of the first return air pipe 301 is connected to the return air port of the thermal furnace 200, which is connected to the air inlet of the blower.

[0052] A steam tank 500 is fixed or placed on the ground on one side of the thermal furnace 200. A steam outlet is connected to the side wall of the steam cylinder 205 at the bottom of the thermal furnace 200. The steam outlet is connected to the steam inlet of the steam tank 500 through a third connecting pipe. A first angle seat valve with a solenoid valve is installed on the third connecting pipe. The steam outlet of the steam tank 500 is connected to the steam inlet pipe 5 of the carbonization box 1000 through a fourth connecting pipe. A second angle seat valve with a solenoid valve is installed on the fourth connecting pipe.

[0053] An air intake pipe 600 is connected to the side wall of the first main air intake pipe 161. A control valve is installed on the air intake pipe 600. The air intake end of the air intake pipe 600 is connected to an air source (the air source is an air tank connected to the air outlet of the air compressor 900, and the air outlet of the air tank is connected to the air intake end of the air intake pipe 600. This is a conventional structure and will not be described in detail).

[0054] Furthermore, two carbonization chambers 1000 are fixed on the ground to the right of the thermal furnace 200. The first main connecting pipe 201 is a three-way connecting pipe. The two air outlets of the first main connecting pipe 201 are respectively connected to the first main air inlet pipe 161 of the two carbonization chambers 1000 through control valves.

[0055] The second main connecting pipe 202 is a three-way connecting pipe, and the outlet ends of the main air outlet pipes 13 of the two carbonization chambers 1000 are connected to a corresponding air inlet of the second main connecting pipe 202 through a control valve.

[0056] Furthermore, the carbon dioxide storage tank 400 is connected to two exhaust connectors 401. The exhaust connectors 401 are fixed to the side wall of the first main air inlet pipe 161 of the corresponding carbonization box 1000 through the second connecting pipe and communicate with the corresponding side through hole on the side wall of the first main air inlet pipe 161 of the corresponding carbonization box 1000.

[0057] Furthermore, the bottom exhaust casing 206 of the thermal furnace 200 has multiple upper through holes formed on its bottom plate. The tops of multiple vertical exhaust pipes 207 are inserted into the corresponding upper through holes, and their outer walls are welded and fixed to the inner walls of the corresponding upper through holes. Below all the vertical exhaust pipes 207, there is an exhaust transition casing 208. The top plate of the exhaust transition casing 208 has multiple lower through holes formed on its top plate. The bottoms of all the vertical exhaust pipes 207 are inserted into the corresponding lower through holes, and the outer walls of the bottoms of all the vertical exhaust pipes 207 are welded and fixed to the inner walls of the corresponding lower through holes. A steam cylinder 205 is welded and fixed to the bottom surface of the base plate of the exhaust housing 206. The bottom end of the steam cylinder 205 is welded and fixed to the top surface of the top plate of the exhaust transition housing 208. All the vertical exhaust pipes 207 are located in the steam cylinder 205. An exhaust end is connected to one side wall of the steam cylinder 205, and a water inlet end is connected to the other side wall. A main exhaust pipe 203 is fixed to the top surface of the top plate of the exhaust transition housing 208. The main exhaust pipe 203 communicates with the through hole formed on the top plate of the exhaust transition housing 208. A water pipe is connected to the water inlet end, and a control valve is installed on the water pipe. This structure allows the control valve on the water pipe to open after the thermal furnace 200 starts heating, enabling liquid water to enter the steam cylinder 205. Exhaust gas flows downwards from the top of all the vertical exhaust pipes 207, exchanging heat with the water and turning it into steam. This steam is then discharged through the exhaust end. The first angle seat valve on the third connecting pipe opens, allowing the steam to enter the steam tank 500 for storage. The steam tank 500 is equipped with a pressure gauge; when the pressure reaches a certain limit, the first angle seat valve closes, and the control valve on the water pipe also closes, stopping water intake. The exhaust gas from the main exhaust pipe 203 is primarily carbon dioxide. This carbon dioxide can be drawn into the carbon dioxide storage tank 400 for storage by opening the control valve on the first connecting pipe and starting the first blower.

[0058] Furthermore, a nitrogen inlet pipe 6 is connected to the side wall of the first main air inlet pipe 161. The inlet end of the nitrogen inlet pipe 6 is connected to the outlet end of the control valve at the outlet of the nitrogen tank 80 on one side of the carbonization box 1000 (the pipeline structure connecting the nitrogen inlet pipe 6 and the nitrogen tank 80 is omitted in the attached figure to make other parts clearer). A control valve is installed on the nitrogen inlet pipe 6.

[0059] Furthermore, a condenser 40 and a dust collector 60 are installed on one side of each of the two carbonization chambers 1000. The outlet of the first circulating air outlet pipe 17 of the carbonization chamber 1000 is connected to the inlet of the corresponding dust collector 60 through a connecting pipe. A control valve is connected between the connecting pipe and the outlet of the first circulating air outlet pipe 17. The outlet of the dust collector 60 is connected to the inlet of the circulating fan 61 through a connecting pipe. The outlet of the circulating fan 61 is connected to the main air inlet connecting pipe 421 of the condenser 40 through a connecting pipe. The main air outlet connecting pipe 431 of the condenser 40 is connected to the inlet of the first circulating air inlet pipe 162 of the corresponding carbonization chamber 1000 through a connecting pipe. A control valve is connected between the inlet of the first circulating air inlet pipe 162 and the connecting pipe.

[0060] Furthermore, a negative pressure tank 50 is provided above the carbonization box 1000. The outlet end of the cooling gas outlet pipe 432 of the condenser 40 is connected to the inlet connector of the negative pressure tank 50 through a connecting pipe, and a control valve is installed on the connecting pipe.

[0061] Furthermore, both negative pressure tanks 50 are connected to suction pipes 55, and each suction pipe 55 is equipped with a control valve. The outlet of each suction pipe 55 is connected to both ends of a three-way connector. One end of the three-way connector is connected to one end of a fifth connecting pipe, and the other end of the fifth connecting pipe is connected to one end of a second three-way connector. The other two ends of the second three-way connector are respectively connected to the first branch suction pipe 56 and the second branch suction pipe 57. The other end of the first branch suction pipe 56 is connected to the inlet of the first vacuum pump 58, and the outlet of the first vacuum pump 58 is open to the outside. The other end of the second branch suction pipe 57 is connected to the inlet of the second vacuum pump 59, and the outlet of the second vacuum pump 59 is connected to the inlet of the first waste gas storage tank 700 placed or fixed around the carbonization box 1000 through a connecting pipe. Both the first branch suction pipe 56 and the second branch suction pipe 57 are equipped with control valves.

[0062] Furthermore, a second waste gas storage tank 800 is vertically located on one side of the first waste gas storage tank 700. The outlet of the first waste gas storage tank 700 is connected to the inlet of the second waste gas storage tank 800 via a connecting pipe. The outlet of the second waste gas storage tank 800 is connected to the gas connection pipe of the thermal furnace 200 (not shown in the attached figure) via a connecting pipe. A control valve is installed on this connecting pipe.

[0063] The carbonization box 1000 in this embodiment includes a main box 10. The main box 10 has an inner box 20 inside. The left ends of the inner box 20 and the main box 10 are fixed on the same left end plate 11. The left end plate 11 covers the left ends of the inner box 20 and the main box 10. The right ends of the inner box 20 and the main box 10 are fixed on the same right door frame 12. One side of the door 30 is movably connected to the right door frame 12 by a hinge. The door 30 is located on the right side of the right door frame 12 and covers the middle through groove of the right door frame 12. The edge of the door 30 is pressed and fixed to the right door frame 12 by multiple door locking devices 31.

[0064] The left end plate 11 has a main air inlet hole 111 formed in the middle. The outer wall of the main air outlet pipe 13 is welded and fixed to the inner wall of the vertical through hole formed on the right top plate of the inner box 20 and the right top plate of the main box 10. The top of the main air outlet pipe 13 extends out of the top surface of the top plate of the main box 10, and the bottom end of the main air outlet pipe 13 extends out of the bottom surface of the top plate of the inner box 20. Multiple protrusions are formed on the outer wall of the bottom end of the main air outlet pipe 13. All protrusions are evenly distributed on the outer wall of the bottom end of the main air outlet pipe 13 with the central axis of the main air outlet pipe 13 as the center. The lower extension sleeve 131 is located at the lower part of the main air outlet pipe 13 and is located in the inner box 20. The upper outer wall of the lower extension sleeve 131 has radial extensions. The annular body has an annular groove formed on its inner sidewall, and multiple upper protrusions are formed on the top inner sidewall of the annular groove. All the upper protrusions are evenly distributed on the top inner sidewall of the annular groove with the central axis of the lower extension sleeve 131 as the center. A slot is formed between two adjacent upper protrusions. The protrusion is first inserted into the corresponding slot and then rotated so that the protrusion is between the corresponding upper protrusion and the bottom surface of the annular groove. At the same time, an upper extension is formed on the top surface of one side of the protrusion. One side of the upper extension rests against the side of the corresponding slot to achieve a limit, thereby realizing the connection between the lower extension sleeve 131 and the bottom end of the main air outlet pipe 13. Multiple side return air passages are formed on the side plate of the lower extension sleeve 131. When the inner material box 100 placed in the inner casing 20 needs to be removed, rotate the lower extension sleeve 131 so that the protrusion faces the corresponding slot. At this time, the upper extension rests against the other side of the corresponding slot, moving it into place and ensuring that the entire protrusion is in the corresponding slot. Then, the lower extension sleeve 131 can be lowered and separated from the main air outlet pipe 13, at which point the inner material box 100 can be removed. Moreover, the lower extension sleeve 131 can be easily cleaned, repaired, and maintained after disassembly. The upper part of the outer side wall of the front and rear of the lower extension sleeve 131 is fixed with a grip for easy operation.

[0065] The inner box 20 is provided with a plurality of inner material boxes 100 arranged in the left and right directions. The inner material boxes 100 are provided with a plurality of central ventilation connecting pipes 1001 extending in the left and right directions. The left and right ends of the central ventilation connecting pipes 1001 are fixed to the left and right side plates of the inner material boxes 100 and communicate with the corresponding through holes on the left and right side plates of the inner material boxes 100 (the end of the central ventilation connecting pipe 1001 is inserted into the corresponding through hole, and its outer side wall is welded and fixed to the inner side wall of the corresponding through hole). A plurality of side air outlet holes are formed on the side wall of the central ventilation connecting pipes 1001.

[0066] A frame plate 2000 is provided between each pair of adjacent inner feeding boxes 100. Two nested frame-shaped sealing rings 2001 are fixed to the left and right walls of the frame plate 2000 (i.e., one frame-shaped sealing ring 2001 on the same side is smaller than the other, with the smaller ring nested within the larger one, achieving double sealing). The frame-shaped sealing rings are made of mica. The left wall of the left frame-shaped sealing ring presses against the right wall of the right side plate of the left inner feeding box 100, and the right wall of the right frame-shaped sealing ring presses against the left wall of the left side plate of the right inner feeding box 100. The left ends of all the central venting connecting pipes 1001 of the inner feeding box 100 face the central through groove of the smaller frame-shaped sealing ring on the left, and the right ends of all the central venting connecting pipes 1001 of the inner feeding box 100 face the central through groove of the smaller frame-shaped sealing ring on the right. The central through groove of the sealing ring, that is, the frame plate 2000 and the frame sealing rings 2001 on both sides between two adjacent inner material boxes 100, enable all the central ventilation connection pipes 1001 between the two adjacent inner material boxes 100 to be connected and isolated from the outside. The left side plate of the leftmost inner material box 100 presses against the right end face of the left end plate 11, and the through hole on the left side plate of the leftmost inner material box 100 is connected to the main air inlet hole 111. A right baffle 1004 is fixed on the right side wall of the inner material box 100 at the far right end. Two frame-shaped sealing rings 2001 that fit together are fixed on the left side wall of the right baffle 1004. Their left end faces press against the right side wall of the inner material box 100 at the far right end. The right ends of all the middle ventilation connecting pipes 1001 of the inner material box 100 at the far right end face the middle through groove of the smaller frame-shaped sealing ring 2001 on the left side of the right baffle 1004.

[0067] In this embodiment, except for the leftmost inner material box 100, the left side wall of the left side plate of each inner material box 100 is fixed with the corresponding frame plate 2000 by bolts.

[0068] By using a frame plate 2000 and a frame sealing ring 2001, the hot air coming out of the main air inlet 111 can only flow into the central ventilation connection pipe 1001 of all the inner discharge boxes 100, and finally be discharged into the inner discharge box 100 through the side air outlet of the central ventilation connection pipe 1001. Moreover, it can ensure that enough hot air can flow from the central ventilation connection pipe 1001 of the leftmost inner discharge box 100 to the central ventilation connection pipe 1001 of the rightmost inner discharge box 100, and be discharged through the corresponding side air outlet, ensuring that the material in each inner discharge box 100 can be heated, burned and carbonized by hot air.

[0069] Alternatively, the left side wall of the left side plate of each inner material box 100 can be fixed with the corresponding frame plate 2000 by bolts. In this case, the left side wall of the two frame-shaped sealing rings 2001 on the left side of the frame plate 2000 of the leftmost inner material box 100 presses against the right end face of the left end plate 11 to achieve sealing and ensure that the through hole on the left side plate of the leftmost inner material box 100 is connected to the main air inlet hole 111.

[0070] The inner feeding box 100 is fixed with a plurality of front and rear extending air guide pipes 1002. The front and rear ends of the air guide pipes 1002 are fixed to the front and rear side plates of the inner feeding box 100 and communicate with the corresponding through holes on the front and rear side plates (the end of the air guide pipe 1002 is inserted into the corresponding through hole, and its outer side wall is welded and fixed to the inner side wall of the corresponding through hole). A plurality of side air inlet through holes are formed on the side wall of the air guide pipe 1002.

[0101] Furthermore, the bottom cavity of the bottom air intake housing 420 has a triangular cross-section, and the distance between the upper parts of the two inclined inner walls is less than the distance between the lower parts of the two inclined inner walls.

[0107] In this embodiment, the outer wall of the main housing 10, as well as the outer wall of all exposed components, pipes, and housings, are all fixed with asbestos insulation layers to ensure heat preservation during equipment operation and reduce heat loss.

[0108] The fans and blowers used in this embodiment are all high-temperature resistant fans, which can be a high-temperature magnetic levitation circulating fan as described in Chinese patent application number 202410001217.8, which will not be described in detail here.

[0109] In this embodiment, during use, firstly, the push rods of all the clamping cylinders 33 are pushed, causing all the hooks 34 to open, thus opening the door 30. Then, all the inner material boxes 100 to be processed are moved to the left along the guide wheels 1003 on the corresponding guide rails 21, placing all the inner material boxes 100 into the inner box 20. The left side plate of the leftmost inner material box 100 is pressed against the right end face of the left end plate 11. Then, the door cover 165 is opened, and the transverse connecting shaft 18 is inserted into the corresponding central through hole. The left end of the transverse connecting shaft 18 extends out of the left end of the corresponding central through hole. A radially extending edge is formed on the outer side wall of the left end of the transverse connecting shaft 18, and the right end face of the radially extending edge is pressed against the left side wall of the support frame 163. The connecting shaft 18 is inserted into the corresponding central ventilation connecting pipe 1001 in the middle of all the inner material boxes 100. Its right end extends out of the through hole on the right side plate of the rightmost inner material box 100 and the central through hole of the right baffle 1004 installed on the right side wall of the right side plate of the rightmost inner material box 100. Then, the pin 181 is inserted into the corresponding two positioning pin through holes and radial through holes. The pressing part formed at the top of the pin 181 presses against the top surface of the guide sleeve 1005. The threaded part formed in the middle of the right end face of the transverse connecting shaft 18 extends out of the right end face of the guide sleeve 1005 and is threaded with two mutually pressing lock nuts. The left end face of the lock nut on the left side presses against the right end face of the guide sleeve 1005 to achieve fixation.

[0110] Then, the control valve connected to the outlet of nitrogen tank 80 is opened, and the control valve on nitrogen inlet pipe 6 is opened, allowing nitrogen to enter the carbonization chamber 1000 from the inlet end of nitrogen inlet pipe 6, venting the gas in the inner chamber 20 of carbonization chamber 1000. Generally, the gas is filled for a certain period of time (such as about 10 minutes). Then, after the door 30 is closed, the push rods of all the clamping cylinders 33 will retract, causing the hook 34 to flip back to its original position, connecting and fixing the door 30 and the right door frame 12. At this time, the inner chamber 20 and the connected pipelines are filled with nitrogen. Then, the control valve connected to the outlet of nitrogen tank 80 is closed, and the control valve on nitrogen inlet pipe 6 is closed.

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

[0112] The material is heated by a thermal furnace 200. High-temperature nitrogen gas enters the left cover 16 from the first main air inlet pipe 161, then enters all the middle ventilation connecting pipes 1001, and then exits from the corresponding side air outlets and ends. The gas exiting from the side air outlets blows onto the material placed on the middle ventilation connecting pipes 1001 and the air guide pipes 1002, providing heat for the material heating, drying and carbonization. Then, part of it is discharged from the flow holes and top of the inner discharge box 100, and part of it enters from the side air inlet holes of the air guide pipes 1002 and is discharged from both ends of the air guide pipes 1002, which increases the flow time of hot gas in the inner discharge box 100. Moreover, since the air guide pipes 1002 and the middle ventilation connecting pipes 1001 are staggered, the material on them is heated evenly, which improves the uniformity of carbonization and enhances the effect.

[0113] During the heating process, nitrogen gas flows through the spiral channel 1. A control valve (of conventional structure, omitted from the attached diagram) is connected to the top of the exhaust pipe 15. When the control valve is closed, the blower stops operating, ensuring that the nitrogen gas in the spiral channel 1 does not flow. Alternatively, a control valve can be connected to the air outlet of the blower and connected to the cooling air inlet pipe 14. When not in use, the control valve is closed (no control valve is installed in this embodiment). Nitrogen gas is introduced into the exhaust pipe 15 by introducing nitrogen gas into the top of the exhaust pipe 15 (by inserting a connecting pipe from the nitrogen tank into the control valve at the top of the exhaust pipe 15). When introducing nitrogen gas, the blower stops operating. After the nitrogen is introduced, the control valve at the top of the exhaust pipe 15 is closed, and the connecting pipe is pulled out.

[0114] Then, the hot air in the inner box 20 flows back to the lower extension sleeve 131 through the side return air passage, then flows to the main air outlet pipe 13, and then flows to the first ash remover 300. After being removed by the first ash remover 300, it returns to the air inlet of the blower connected to the return air port of the thermal furnace 200 through the first return air pipe 301, realizing circulation. It is then circulated and heated by the thermal 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 filter bag for dust collection and 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 regular intervals to replenish oxygen to the inner chamber 20 at regular intervals and in a quantitative manner, so that the material can be fully combusted.

[0116] After heating to a certain temperature, such as 150°C (the temperature is sensed by temperature sensor 3 and the data is transmitted to the control host), the control valves set at the main exhaust pipe 13 and the first main intake pipe 161 of the carbonization box 1000 at the front are closed. At this time, the control valves set at the main exhaust pipe 13 and the first main intake pipe 161 of the carbonization box 1000 at the rear are opened, so that the thermal furnace 200 supplies heat to the carbonization box 1000 at the rear. 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 air outlet 17 of the carbonization chamber 1000 is opened, and the control valve at the first circulation air inlet 162 is opened. At the same time, the control valve of the air inlet 600 continues to open and close at regular intervals to introduce oxygen into the left cover 16, thereby providing oxygen to the inner chamber 20 so that the material inside can be fully burned and carbonized. During the combustion process, the circulating fan 61 runs, causing the hot gas in the inner chamber 20 to enter the dust collector 60. After dust removal, it enters the condenser 40. At this time, the cooling water in the condenser 40 does not flow, so the gas does not condense. Then, it returns to the inner chamber 20 for combustion. When the temperature reaches 450°, the control valve of the air inlet 60 closes, oxygen supply stops, and the gas continues to flow.

[0118] During the entire heating or gas circulation process, when the pressure becomes too high (exceeding 2 kPa, as sensed by pressure sensor 4), the control valve on the connecting pipe between the outlet of the cooling gas outlet pipe 432 of the condenser 40 and the inlet of the negative pressure tank 50 needs to be opened. Simultaneously, the cooling water in the condenser 40 flows. As the gas passes through the condenser 40, its temperature drops significantly, and substances such as water and grease in the hot gas are discharged. A portion of the gas exiting the condenser 40 enters the negative pressure tank 50 through the cooling gas outlet pipe 432 for storage, thereby reducing the pressure in the inner casing 20. When the pressure is less than 2 kPa, the control valve on the connecting pipe between the outlet of the cooling gas outlet pipe 432 and the inlet of the negative pressure tank 50 closes. At this time, the control valve on the second extraction pipe 57 opens, and the second vacuum pump 59 operates, drawing the gas absorbed from the negative pressure tank 50 into the first waste gas storage tank. In the gas tank 700, when the first waste gas storage tank 700 is full, it flows 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 that connects it to the gas connection pipe of the thermal furnace 200 can be opened, allowing the sucked-in gas to enter the gas connection pipe of the thermal furnace 200 and be used as auxiliary fuel (the gas sucked in by the negative pressure tank 700 is the gas from the combustion of materials, which contains a large amount of organic matter and other substances that can be used as auxiliary fuel), thus reducing 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 that connects to the gas connection pipe of the thermal furnace 200 is closed, the control valve on the second gas extraction pipe 57 is closed, and the control valve on the connecting pipe that connects the outlet end of the cooling gas outlet pipe 432 to the inlet connector of the negative pressure tank 50 is opened to continue to adsorb and use excess gas.

[0119] After running at 450° for a certain period of time, carbonization is basically completed. The control valve at the second connecting pipe is opened, allowing carbon dioxide from the exhaust connector 401 of the carbon dioxide storage tank 400 to enter the corresponding first main air inlet pipe 161, and then into the inner box 20. At the same time, steam is introduced into the steam inlet pipe 5 (the steam is introduced by opening the second angle seat valve of the corresponding fourth connecting pipe of the steam tank 500). The steam first enters the annular pipe 1631, and then exits from the multiple steam branch holes on the extension pipe 1632, entering the inner box 20. Together with the carbon dioxide, it activates the material in the inner discharge box 100. After a certain period of time, the activation is completed, and then both steam and carbon dioxide are stopped being added.

[0120] Then, cooling is performed. During cooling, the control valve connected to the top of the exhaust pipe 15 is opened, the blower is turned on, and external gas is introduced into the spiral channel 1 to expel the nitrogen inside, and to rapidly cool the main chamber 10 and the inner chamber 20. At this time, the control valves at the main exhaust pipe 13 and the first main intake pipe 161 are still closed, while the control valve at the air inlet of the first circulating air outlet pipe 17 is still open, and the control valve at the first circulating air inlet pipe 162 is open. The circulating fan 61 runs, allowing the hot air in the inner chamber 20 to enter the dust collector 60 for dust removal, and then enter the condenser 40 for condensation. At this time, the condenser 4... The cooling water in chamber 0 continues to flow, thus continuing to cool the gas and materials in the inner chamber 20 until the temperature drops to about 80°C. Then, the door 30 can be opened, and 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 pipe 164 (it requires a robot or clamp to be inserted into the disassembly pipe 164, and its end is screwed onto the screwed part at the left end of the transverse connecting shaft 48. Pull it outward to pull out the transverse connecting shaft 48). At this time, all the inner material boxes 100 can be removed from the inner chamber 20. The operation is convenient and the effect is good.

[0121] After one carbonization chamber 1000 is completed, the other carbonization chamber 1000 is operated in the same way. When neither of the two carbonization chambers 1000 needs heat from the thermal furnace 200, the thermal furnace 200 can reduce its combustion rate, but it still needs to be kept in combustion state. This is because, during the heating process from 150° to 450°, when the temperature inside the carbonization chamber 1000 can no longer rise, the corresponding two control valves need to be opened so that the gas in the inner chamber 20 of the corresponding carbonization chamber 1000 passes through the thermal furnace 200 again to raise its temperature. After running for a certain period of time, the corresponding two control valves are closed to achieve self-circulation between the carbonization chamber 1000 and the corresponding condenser 40 and dust collector 60, so as to continue to raise the temperature.

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

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

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

[0125] After cooling, some water droplets or oil will form in the gas, which will fall down the inner tube 414 and enter the lower cylindrical body 422 from the bottom air inlet shell 420. The liquid level in the lower cylindrical body 422 can be viewed through the level gauge 425. When the liquid exceeds the sensing end of the level sensor 426 (in this embodiment, the level sensor 426 is a photoelectric level sensor, which uses the principle of reflection and refraction of light at the interface of two different media to achieve sensing), the level sensor 426 senses the liquid. When it senses the liquid, the control host receives the signal transmitted by the level sensor 426 and processes it. Then, it opens the first solenoid valve at the oil outlet pipe 424 until the level sensor 426 is no longer in use. When liquid is detected, the first solenoid valve at the oil outlet pipe 424 closes. Then, the control unit controls the first solenoid valve at the liquid outlet connection pipe 423 to open, allowing water to flow out from the liquid outlet connection pipe 423. This usually lasts for about 60 seconds. Alternatively, the first solenoid valve at the liquid outlet connection pipe 423 can be manually closed based on the decrease in the liquid level at the liquid level gauge 425. The oil and some water above the sensing end of the liquid level sensor 426 can be discharged from the oil outlet pipe 424 (usually oil, occasionally some water, but this does not affect the discharge); the remaining water is discharged from the liquid outlet connection pipe 423 (occasionally a small amount of oil may be mixed in the liquid outlet connection pipe 423, but this does not affect the discharge).

[0126] The liquid discharged from its liquid outlet connection pipe 423 and oil outlet pipe 424 can be further processed and reused.

[0127] It can automatically discharge the water and oil generated during cooling in real time, reducing accumulation, ensuring normal operation of the equipment, and providing good performance. Among them, the oil outlet pipe 424 and the liquid outlet connection pipe 423 can be connected to the discharge tank or other containers to store the discharged liquid.

[0128] In this embodiment, when the dust collector 60 is in use, hot air enters through the right air inlet connector 63. The airflow time within the dust collector 60 is increased by the obstruction of multiple intermediate partitions 621 (each partition 621 has multiple through holes to ensure the hot air can flow out and be guided). Then, after being filtered through the filter screens 66 with progressively increasing mesh sizes, dust particles of the corresponding size fall into the corresponding dust collection cylinder 65, at which point the discharge control valve 67 at the bottom opens. Dust can simply fall into the storage bag connected to the bottom of the discharge control valve 67. The storage bag has 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 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 and outlet pipes are connected to the water-cooled chiller unit, which has a conventional structure and can be purchased directly, and will not be described in detail here). This allows cooling water to circulate in the cooling ring assembly 66, cooling the dust passing through the cooling ring assembly 66 and ensuring that the temperature of the dust entering the storage bag is not high, thus ensuring high safety.

[0129] Meanwhile, during use, the timed vibration of the vibration motor 68 can prevent dust accumulation in the dust collection cylinder 65 and ensure normal material discharge. At the same time, the vibration transmission to the dust collection main box 62 can also vibrate the corresponding filter screen 66, preventing the dust accumulation on it from falling off and improving the dust removal effect.

[0130] In this embodiment, the first vacuum pump 58 is activated when the negative pressure tank 50 is used after maintenance or shutdown. The control valve of the first branch suction pipe 56 is opened, and the first vacuum pump 58 is turned on to pump out the gas in the negative pressure tank 50, creating a negative pressure and ensuring that there is no other gas inside. Then, the control valve of the first branch suction pipe 56 is closed to complete the pumping. This operation is to prevent the negative pressure tank 50 from mixing with the gas that enters later due to the presence of air, which could cause combustion or even explosion, thus improving the safety protection effect.
