Description

Technical Field

[0001] The present invention relates to the technical field of biochar preparation, and in particular to a biochar preparation device based on charcoal-gas cogeneration. Background Art

[0002] The process of preparing biochar through dry distillation and pyrolysis of biomass agricultural and forestry waste after crushing and drying is a systematic, multi-step thermochemical conversion process. Before dry distillation, the biomass raw materials need to be crushed and dried to ensure that their physical and chemical properties are suitable for the subsequent pyrolysis reaction. During the dry distillation process, the dried biomass raw materials are heated to a high temperature under anaerobic or anoxic conditions to cause thermal decomposition to produce solid biochar and gaseous combustible gas products. Heat transfer is carried out through conduction, convection and radiation. Heat conduction affects the adequacy of the biomass raw material dry distillation process.

[0003] For example, the patent with publication number CN212357142U discloses a biomass pyrolysis system, which includes a biomass drying tube, a carrier heating tube, a pyrolysis reactor, a first cyclone separator, a second cyclone separator, a waste heat boiler, a bio-oil spray tower and an oil and gas hot air furnace; the air outlet end of the biomass drying tube is connected to the first cyclone separator, and the air inlet end of the biomass drying tube is connected to the air outlet end of the flue gas in the waste heat boiler. The biomass drying tube contains biomass, and the flue gas discharged by the waste heat boiler is used to dry the biomass in the biomass drying tube; the air inlet end of the flue gas in the waste heat boiler is connected to the upper end of the carrier heating tube, and the waste heat boiler is used to absorb the heat of the hot air transported by the carrier heating tube to generate steam. At the same time, the cooled hot air is transported to the air inlet end of the biomass drying tube by the waste heat boiler, thereby improving the heat utilization rate of the pyrolysis system.

[0004] For example, the patent with publication number CN112430470A discloses a pyrolysis furnace for pyrolyzing biomass, which includes an inner liner, a support member and an insulation layer. The inner liner is placed horizontally in the support member and is located inside the insulation layer. A combustion chamber is provided between the inner liner and the insulation layer, and a filling port is provided at the end of the inner liner; a combustion point is provided at the bottom of the insulation layer, and the combustion points are evenly distributed at the bottom of the insulation layer; such a biomass pyrolysis furnace adds biomass, such as fruit wood, through the filling port located at the end of the inner liner. The filling is convenient and low-cost, which can reduce the pyrolysis cost of the biomass; in addition, a combustion chamber is provided between the inner liner and the insulation layer of the biomass pyrolysis furnace, so that the biomass in the inner liner can be directly heated, thereby improving the thermal utilization rate of fuel combustion and effectively reducing the pyrolysis cost of the biomass.

[0005] For example, the patent with publication number CN117987157A discloses a biomass pyrolysis furnace, which includes a furnace body, a return air pipe and a recovery pipe. The return air pipe is located above the furnace body and is connected to the inner cavity of the furnace body. The return air pipe is unidirectionally connected to the recovery pipe through a connection control mechanism. The biomass pyrolysis furnace is provided with a connection control mechanism between the return air pipe and the recovery pipe, so that the connection and disconnection between the return air pipe and the recovery pipe can be controlled by the connection control mechanism as needed to prevent the combustible gas in the recovery pipe from flowing back into the furnace body through the return air pipe, thereby affecting the recovery efficiency of the combustible gas.

[0006] Due to the large internal space of the barrel, the temperature distribution of the biomass raw materials is uneven. The biomass raw materials near the inner wall of the barrel have a higher temperature due to faster heat conduction and a faster reaction rate. They may be more likely to undergo cracking reactions and generate more volatile products. However, the biomass near the center of the barrel has a longer heat conduction path and a lag in heat conduction, resulting in a lower temperature and a slower reaction rate. Dehydration, decarbonylation and other reactions may occur, and the generated products may be more solid or semi-solid. This temperature gradient may cause the biomass raw materials near the center of the barrel to fail to reach a sufficient reaction temperature, thereby affecting the depth of its dry distillation and pyrolysis reaction and the efficiency of product generation.

[0007] In response to the above problems, there is an urgent need to carry out innovative designs based on the original biochar preparation equipment. Summary of the Invention

[0013] Preferably, a mounting frame is fixedly installed in the pyrolysis furnace, a driving gear is rotatably connected to the mounting frame, and the driving gear is meshed with the ring gear.

[0014] Preferably, a plurality of hot air pipes are slidably connected to the side wall of the barrel at equal intervals, the air inlets of the hot air pipes are connected to the interior of the pyrolysis furnace, and a flap is fixedly sleeved on the plurality of hot air pipes to disperse the biomass waste at the center of the barrel; a transmission mechanism is provided in the pyrolysis furnace to drive the hot air pipes and the flap to push the biomass waste back and forth, and the transmission mechanism drives the hot air pipes to move back and forth to keep the heat evenly distributed in the biomass waste.

[0016] Preferably, a rack is fixedly connected to one side of the rectangular frame close to the barrel, and the rack is meshed with the gear ring.

[0018] Preferably, a transmission rod is rotatably connected to the vibration ring, and the other end of the transmission rod is rotatably connected to the cross bar.

[0019] Compared with the prior art, the beneficial effects of the present invention are: when preparing biochar by carbon-gas co-production, the biochar preparation device based on carbon-gas co-production can rotate, shake and disperse the biomass waste in the barrel, and can synchronously push the biomass raw materials at the center of the barrel, so that the biomass raw materials on the inner wall and the center of the barrel can be moved and dispersed, the fluidity of the biomass raw materials in the barrel is enhanced, and the efficiency and effect of the dry distillation and pyrolysis processing are effectively improved.

[0020] Furthermore, the barrel is provided with a driving mechanism for driving the arc plate and the mesh plate to rotate back and forth and vibrate to disperse the biomass waste. The biomass waste is distributed on the arc plate and the mesh plate. During the pyrolysis process, the arc plate and the mesh plate can be controlled to rotate back and forth through the meshing transmission of the driving gear and the ring gear, so that the biomass waste at the center of the barrel and the biomass waste near the inner wall are exchanged. Under the transmission of the slide rod and the arc-shaped groove, the arc plate and the mesh plate can be controlled to vibrate back and forth, so that the biomass waste in the upper and lower directions of the barrel moves and exchanges positions, thereby enhancing the uniformity of the distribution of the biomass waste in the barrel, so that the biomass waste at different positions can effectively absorb the heat in the pyrolysis furnace, and improve the pyrolysis carbonization effect.

[0021] There are multiple hot air pipes slidingly connected at equal intervals on the side wall of the barrel. The hot air pipes can transfer the heat in the pyrolysis furnace to the center of the barrel, thereby improving the heat transfer effect. At the same time, the rotation and vibration of the biomass waste can be controlled. Under the meshing transmission of the rack and the ring gear, the hot air pipes and the flap can be controlled to move back and forth laterally in the barrel. The reciprocating movement of the hot air pipe can effectively transfer heat, and the reciprocating movement of the flap can push the biomass raw materials at the center of the barrel, thereby improving the fluidity of the biomass raw materials at the center of the barrel and the biomass raw materials at the barrel wall, thereby further improving the uniform pyrolysis processing of the biomass raw materials.

[0022] Furthermore, a material separation mechanism for treating biomass particles in the flue gas is provided in the flue gas treatment channel. During the pyrolysis process of biomass waste, some lightweight particles are mixed in the flue gas due to rotation and vibration. When the flue gas is discharged, the lightweight particles can be isolated through the filter, thereby reducing charcoal production losses and also reducing the pollution of the flue gas.

[0023] When the biomass waste rotates back and forth, the cross bar rotates back and forth along the circumferential direction of the barrel, and the two ends of the transmission rod connected between the cross bar and the vibration ring rotate. The rotating transmission rod can push the vibration ring and the vibration frame to move up and down, so that the vibration frame vibrates on the surface of the filter screen, maintaining the continuity of the filter screen in filtering the flue gas.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solutions: a biochar preparation device based on carbon-gas cogeneration, comprising a pyrolysis furnace 1 for providing heat for biomass waste, a barrel 2 is fixedly installed through the pyrolysis furnace 1, and sealing doors 3 are rotatably installed at the front and rear ends of the barrel 2, a flue gas treatment channel 4 is fixedly installed between the barrel 2 and the pyrolysis furnace 1, and an exhaust pipe 5 is connected to the top of the flue gas treatment channel 4; a rotating ring 6 is rotatably installed in the barrel 2, and a guide column 7 is fixedly connected next to the rotating ring 6, and a positioning ring 8 is slidably sleeved on the guide column 7, and arc plates 9 are fixedly installed at the upper and lower ends of the positioning ring 8, and two groups of mesh plates 10 are arranged between the upper and lower arc plates 9, and the mesh plates 10 are fixedly installed on the positioning ring 8; a driving mechanism for driving the arc plates 9 and the mesh plates 10 to reciprocate and vibrate to disperse the biomass waste is provided on the barrel 2; a material separation mechanism for treating biomass particles in the flue gas is provided in the flue gas treatment channel 4.

[0042] See also Figures 4-10 The drive mechanism includes a rectangular slot 91 formed in the upper arc plate 9. A crossbar 92 is fixedly connected transversely to the rectangular slot 91. A vertical rod 93 is fixed vertically to the crossbar 92. The barrel 2 is provided with an arcuate slot 931 that slidably engages with the vertical rod 93. A fixed ring 94 is fixedly sleeved on the outside of the barrel 2. A gear ring 95 is rotatably connected to the fixing ring 94 and rotatably sleeved on the outside of the barrel 2. A shielding piece 96 is fixedly connected to the gear ring 95. The shielding piece 96 blocks and protects the outside of the arcuate slot 931. A connecting rod 961 is fixedly connected between two horizontally adjacent shielding pieces 96. The vertical rod 93 passes through and slides in the shielding piece 96.

[0043] See also Figure 5-Figure 12 A support plate 97 is fixedly connected to the fixing ring 94. The support plate 97 has an arc-shaped groove 98. A slide rod 99 is slidably connected through the arc-shaped groove 98. The slide rod 99 is vertically fixed to the vertical rod 93. A mounting frame 951 is fixedly installed in the pyrolysis furnace 1. A driving gear 952 is rotatably connected to the mounting frame 951. The driving gear 952 is meshed with the ring gear 95.

[0044] After the biomass agricultural and forestry waste is crushed and dried, it is introduced into the barrel 2. The biomass waste is layered on the mesh plate 10 and the arc plate 9 so that heat can circulate in the barrel 2. The pipe wall sealing door 3 is rotated, and the high-temperature heat generated by the pyrolysis furnace 1 is transferred to the barrel 2, so that the biomass waste inside the barrel 2 is pyrolyzed to produce biochar and flue gas. The biochar is retained on the mesh plate 10 and the arc plate 9, and the flue gas is discharged outward through the flue gas treatment channel 4 and the exhaust pipe 5.

[0045] During pyrolysis processing, the motor next to the operating mounting frame 951 controls the drive gear 952 to rotate back and forth, and the drive gear 952 is meshed and connected with the ring gear 95 on the outside of the barrel 2. Under the meshing transmission, the ring gear 95 can be controlled to be sleeved on the outside of the barrel 2 to rotate back and forth, and the ring gear 95 drives the shielding piece 96 fixed on the side to rotate synchronously. The shielding piece 96 drives the vertical rod 93, the horizontal rod 92, and the arc plate 9 to rotate synchronously. The arc plate 9 controls the positioning ring 8 and the rotating ring 6 to rotate correspondingly inside the barrel 2. The arc plate 9 and the mesh plate 10 fixed on the positioning ring 8 rotate synchronously, so that the biomass waste on the arc plate 9 and the mesh plate 10 rotate back and forth, so that the biomass waste on the inner wall and the center position of the barrel 2 moves to alternate positions, so as to ensure that the biomass waste absorbs heat evenly.

[0046] When the arc plate 9 and the vertical rod 93 rotate back and forth, the sliding rod 99 on the vertical rod 93 slides through the arc-shaped groove 98. When the sliding rod 99 moves along the direction of the arc-shaped groove 98, it can drive the reciprocating arc plate 9 to move back and forth longitudinally. The arc plate 9 drives the positioning ring 8 mounted on the outside of the guide column 7 to move longitudinally. The positioning ring 8 drives the arc plate 9 and the mesh plate 10 to move back and forth longitudinally synchronously, which has a shaking effect on the biomass waste on the arc plate 9 and the mesh plate 10, so that the biomass waste is shaken and dispersed longitudinally, so that heat can be better transferred to the biomass waste. At the same time, the longitudinally shaken biomass waste moves to alternate positions, further maintaining the uniformity of the distribution of the biomass waste in the barrel 2.

[0047] Example 2: Please refer to Figure 3 、 Figure 11-13On the basis of the first embodiment, a hot air pipe 11 is further disclosed, and its specific structure is as follows: a plurality of hot air pipes 11 are slidably connected to the side wall of the barrel 2 at equal intervals, and the air inlet of the hot air pipe 11 is connected to the interior of the pyrolysis furnace 1, and a flap 12 for dispersing the biomass waste at the center of the barrel 2 is fixedly sleeved on the plurality of hot air pipes 11; a transmission mechanism is provided in the pyrolysis furnace 1 to drive the hot air pipe 11 and the flap 12 to reciprocate and push the biomass waste, and the transmission mechanism drives the hot air pipe 11 to move back and forth to keep the heat evenly distributed in the biomass waste.

[0048] See also Figure 11-13 The transmission mechanism includes a lifting frame 111 fixedly connected to the mounting frame 951. A rectangular frame 112 is fixedly mounted on the lifting end of the lifting frame 111, and a rotating support rod 114 is rotatably connected to the rectangular frame 112. A shift plate 115 is fixedly mounted on the outside of the two adjacent hot gas pipes 11 in the middle, and the shift plate 115 is rotatably connected to the rotating support rod 114. A rack 113 is fixedly connected to the side of the rectangular frame 112 near the barrel 2, and the rack 113 is meshed with the ring gear 95.

[0049] The hot air pipe 11 can absorb and transfer the heat in the pyrolysis furnace 1 and transfer the heat to the center of the barrel 2. At the same time, when the arc plate 9 and the mesh plate 10 are controlled to rotate back and forth and shake longitudinally, the gear ring 95 outside the barrel 2 rotates back and forth, and the gear ring 95 is engaged with the rack 113. Under the meshing transmission, the rack 113 and the rectangular frame 112 can be controlled to move back and forth longitudinally. The two ends of the rotating support rod 114 connected between the rectangular frame 112 and the shift plate 115 rotate accordingly, and the rotating rotating support rod 114 pushes the shift plate 115 to move back and forth laterally. The shift plate 115 controls the hot air pipe 11 to move back and forth laterally through the inner wall of the barrel 2. The lateral movement of the hot air pipe 11 can improve the heat transfer effect and keep the heat evenly distributed in the barrel 2. At the same time, the hot air pipe 11 drives the flap 12 to move back and forth laterally. The flap 12 is close to the central axis of the barrel 2. The lateral reciprocating movement of the flap 12 can further assist the biomass waste at the center position of the barrel 2 and the biomass waste at the barrel wall position to move to alternate positions, so as to ensure that the biomass waste at various locations in the barrel 2 fully absorbs heat to complete the pyrolysis process.

[0050] Example 3: Please refer to Figure 14 and Figure 15 In addition to the first and second embodiments, a material separation mechanism is also disclosed. Its specific structure is as follows: the material separation mechanism includes a filter screen 13 embedded and fixed in the flue gas treatment channel 4. Filter screen 13 is used to isolate biomass particles mixed in the flue gas. A vibrating ring 14 is slidably installed in the flue gas treatment channel 4 along the direction of flue gas flow. Vibrating ring 14 is positioned directly below filter screen 13, and a vibrating frame 15 is fixedly mounted on the upper end surface of vibration ring 14 to vibrate filter screen 13. A transmission rod 16 is rotatably connected to vibration ring 14, and the other end of transmission rod 16 is rotatably connected to crossbar 92.

[0051] The flue gas generated by the pyrolysis process is discharged outward through the flue gas treatment channel 4 and the exhaust pipe 5. Since the biomass raw materials in the barrel 2 are rotated and shaken, some lightweight particulate matter will be mixed in the flue gas. The filter 13 in the flue gas treatment channel 4 can isolate and filter the particulate matter in the flue gas, reduce the loss in the preparation of biochar, and also reduce the pollution of the flue gas discharge.

[0052] When the cross bar 92 and the vertical bar 93 rotate back and forth, both ends of the transmission rod 16 connected between the cross bar 92 and the vibration ring 14 rotate, and the rotating transmission rod 16 pushes the vibration ring 14 to move longitudinally inside the flue gas treatment channel 4. When the vibration ring 14 moves longitudinally, it can drive the vibration frame 15 to move back and forth synchronously. The reciprocating movement of the vibration frame 15 acts on the surface of the filter 13, keeping the filter 13 continuously filtering and isolating particulate matter in the flue gas.

For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
