Description

Technical Field

[0001] This invention belongs to the technical field of laboratory biomass carbonization instruments, and particularly relates to an electromagnetic instantaneous heating experimental batch carbonization instrument. 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 (usually solid) products.

[0003] Currently, there are no dedicated instruments and equipment for biochar preparation from biomass in domestic and international research laboratories. The main equipment used in existing laboratories for biochar preparation is the muffle furnace and the tube furnace. However, both have the following obvious disadvantages in actual production: low output (basically 200g / day), long heating and cooling time during carbonization, small carbonization amount, environmentally unfriendly, strong exhaust odor, and accumulation of tar, wood vinegar, etc., which do not meet environmental emission requirements.

[0004] Therefore, it is necessary to invent an electromagnetic instantaneous heating experimental batch carbonization instrument to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an electromagnetic instantaneous heating experimental batch carbonization instrument to solve the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electromagnetic instantaneous heating experimental batch carbonization instrument, comprising a carbonization box, wherein both sides of the carbonization box are provided with placement openings, and insulated doors are installed at the placement openings; two carbonization tubes are arranged side by side inside the carbonization box, and both ends of the carbonization tubes are designed to be open; a U-shaped buckle is fixedly connected to the carbonization tube, and the buckle is fixedly connected to the bottom inner wall of the carbonization box; a U-shaped tube is connected to the top of the carbonization tube, and multiple exhaust pipes are vertically connected to the top of the U-shaped tube; an electromagnetic coil is sleeved on the outside of the carbonization tube; an inner liner is inserted into both ends of the carbonization tube, and several through holes are opened through the top of the inner liner, and the several through holes are all located on the same straight line; a sealing component is provided inside the inner liner, and the ends of the two inner liners located on the same side are sleeved with the same sealing cap;

[0007] The top of the carbonization box is fixedly connected to a flue gas combustion box, and the top of the exhaust pipe is inserted through the flue gas combustion box. An igniter is installed on the inner wall of the flue gas combustion box, the top of the flue gas combustion box is connected to an exhaust pipe, and an air inlet valve is connected to one side of the flue gas combustion box.

[0008] Furthermore, the sealing assembly includes a rotating shaft inserted into the inner liner. A circular plate is fixedly sleeved on one end of the rotating shaft. Sealing strips are symmetrically arranged at the top and bottom of the rotating shaft within the inner liner, and the length of the sealing strips is greater than the distribution length of the multiple through holes. Multiple connecting rods are vertically fixedly connected between the sealing strips and the rotating shaft. A handle is fixedly connected to the other end of the rotating shaft. A sealing ring is sleeved on the end of the rotating shaft near the handle. A fixing rod is fixedly connected to the inner side of the sealing ring, located on the diameter of the sealing ring and fixedly sleeved on the rotating shaft. Fan-shaped sealing plates are symmetrically arranged on the front and rear sides of the fixing rod, and two of the sealing... The sum of the areas of the sealing plates and the fixing rod is equal to the cross-sectional area of ​​the inner side of the liner. A fixing shaft is fixedly connected between the two opposite sides of the sealing plates. The fixing shaft is inserted into the fixing rod in the front-back direction. Limiting blocks are fixedly connected to the top and bottom of the sealing ring. Limiting grooves are opened on the inner walls of the top and bottom of the liner at positions opposite to the two limiting blocks. The limiting grooves are parallel to the fixing rod, and the side of the limiting groove near the opening of the liner is connected to the end of the liner. The same annular groove is opened on the inner wall of the liner on the other side of the two limiting grooves, and the annular groove is connected to the limiting groove. A locking component is provided on the side of the sealing ring near the handle.

[0009] Furthermore, the locking assembly includes two L-shaped blocks, which are respectively fixedly connected to the side of the sealing plate near the handle, and the top of the L-shaped block protrudes beyond the top of the sealing plate. An arc-shaped protrusion is fixedly connected to the side of the sealing ring near the handle, and the center of the arc-shaped protrusion is the same as the center of the sealing ring. An arc-shaped strip is slidably installed on the arc-shaped protrusion, and the L-shaped block is located between the arc-shaped strip and the sealing ring. A lever is vertically fixedly connected to the side of the arc-shaped strip away from the sealing ring.

[0010] Furthermore, several temperature sensors are installed inside the electromagnetic coil and the flue gas combustion chamber. Air intake fans are installed on the front and rear sides of the carbonization chamber. A heat dissipation vent is opened at the bottom of the carbonization chamber. A heat dissipation valve is installed at the bottom of the heat dissipation vent. The heat dissipation valve, electromagnetic coil, air intake valve, igniter, temperature sensors, and air intake fans are all connected to the computer host in the background.

[0011] Furthermore, a number of levers are symmetrically fixedly connected to the top and bottom of the rotating shaft, and a scraper is fixedly connected to the side of the lever away from the rotating shaft. The scraper on the lever at the top of the rotating shaft and the scraper on the lever at the bottom of the rotating shaft are rotationally symmetrical about the rotating shaft.

[0012] Furthermore, a number of strip-shaped protrusions are fixedly connected to the side of the sealing strip near the rotating shaft. One end of each strip-shaped protrusion is inclined towards the sealing plate, and the strip-shaped protrusions on the two sealing strips are rotationally symmetrical about the rotating shaft.

[0013] Furthermore, the diameter of the inner liner opening is larger than its overall diameter, and the diameters of the sealing ring and the circular plate are respectively matched with the inner liner opening and the overall diameter of the inner liner.

[0014] Furthermore, the sealing strip is fixedly connected to the circular plate on the side closest to the circular plate. The side view of the sealing plate is arc-shaped, and the center of the sealing plate coincides with the axis of the rotating shaft. The maximum distance between the two sealing strips on opposite sides is equal to the diameter of the circular plate, and the width of the sealing plate is greater than the diameter of the through hole.

[0015] Furthermore, an annular plate is fixedly sleeved at one end of the inner liner near its opening, and the distance from the annular plate to the opening of the inner liner is equal to the depth of the sealing cap.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. Compared with most existing laboratory muffle furnaces or tube furnaces, this invention uses dual carbonization tubes for simultaneous carbonization, and the same biomass material or four different biomass materials can be placed in the four inner liner at the same time for carbonization, thereby increasing the amount of carbonization per batch. In addition, since oxygen is isolated throughout the carbonization process, the quality of the biochar obtained is also relatively high. The flue gas generated during the carbonization process can be completely burned in the combustion chamber, thereby avoiding the production of wood vinegar and tar during the carbonization of biomass materials, and also avoiding environmental pollution.

[0018] 2. This invention features a sealing assembly. When biomass is added to the inner liner, the sealing strip blocks the through-hole, preventing leakage of biomass during loading. After the biomass is added, the sealing plate seals the opening of the inner liner, preventing accidental opening during movement. After carbonization, the sealing cap is removed, and the handle is rotated to reseal the through-hole, preventing air from entering and causing spontaneous combustion of the biochar when the inner liner is removed. Once the biochar in the inner liner has completely cooled, the handle is pulled to move the rotating shaft, causing the circular plate to move outward. As the circular plate moves out of the inner liner, it carries the biochar out with it, improving biochar removal efficiency.

[0019] 3. This invention features strip-shaped protrusions on the sealing strips. When the inner liner is in a horizontal state, there is a gap between the top of the biomass material and the top inner wall of the horizontal inner liner. At this time, the handle can be held and the shaft can be rotated by the handle. As the shaft rotates, the two sealing strips can agitate the biomass material in the inner liner. During the agitation process, the strip-shaped protrusions on the sealing strips can push the biomass material gathered at the end of the inner liner away from the opening towards the opening of the inner liner, thereby making the distribution of biomass material in the inner liner more uniform, and thus improving the carbonization efficiency and carbonization effect of the biomass material.

[0020] 4. This invention features a paddle plate. After the biomass material in the inner liner is evenly distributed by the strip-shaped protrusions, the paddle plate is rotated by the handle towards the scraper, thus turning the paddle plate from its original vertical position to a horizontal position. As the paddle plate gradually turns to a horizontal position, the scraper can scoop some of the biomass material to the top of the horizontal paddle plate, resulting in a vertical distribution of the biomass material in the inner liner. This reduces the thickness of the biomass material during carbonization, thereby further improving the carbonization efficiency of the biomass material in the subsequent carbonization process.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0033] Example 1:

[0034] This invention provides, for example Figures 1 to 10 The electromagnetic instantaneous heating experimental batch carbonization instrument shown includes a carbonization box 1. The carbonization box 1 has placement openings on both sides, and insulation doors 2 are installed at the placement openings. Two carbonization tubes 3 are arranged side by side inside the carbonization box 1, and both ends of the carbonization tubes 3 are designed to be open. A U-shaped buckle is fixedly connected to the carbonization tube 3 and is fixedly connected to the bottom inner wall of the carbonization box 1. A U-shaped tube 4 is connected to the top of the carbonization tube 3, and multiple exhaust pipes 5 are vertically connected to the top of the U-shaped tube 4. An electromagnetic coil 6 is sleeved on the outside of the carbonization tube 3. An inner liner 7 is inserted into both ends of the carbonization tube 3, and several through holes are opened through the top of the inner liner 7, and the several through holes are all located on the same straight line. A sealing component 8 is provided inside the inner liner 7, and the ends of the two inner liners 7 located on the same side are sleeved with the same sealing cap 9.

[0035] A flue gas combustion chamber 10 is fixedly connected to the top of the carbonization chamber 1, and the top of the exhaust pipe 5 is inserted through the flue gas combustion chamber 10. An igniter 11 is installed on the inner wall of the flue gas combustion chamber 10. A smoke exhaust pipe 12 is connected to the top of the flue gas combustion chamber 10. An air inlet valve 13 is connected to one side of the flue gas combustion chamber 10. An annular plate 20 is fixedly fitted to the end of the inner liner 7 near its opening, and the distance from the annular plate 20 to the opening of the inner liner 7 is equal to the depth of the sealing cover 9. Both the electromagnetic coil 6 and the inside of the flue gas combustion chamber 10 are equipped with... The carbonization box 1 is equipped with several temperature sensors. Air intake fans 15 are installed on both the front and rear sides of the carbonization box 1. A heat dissipation vent 16 is opened at the bottom of the carbonization box 1. A heat dissipation valve is installed at the bottom of the heat dissipation vent 16. The heat dissipation valve, electromagnetic coil 6, air intake valve 13, igniter 11, temperature sensors and air intake fans 15 are all connected to the computer host in the background. The diameter of the opening of the inner liner 7 is larger than its overall diameter. The diameters of the sealing ring 806 and the circular plate 802 are respectively matched with the opening of the inner liner 7 and the overall diameter of the inner liner 7.

[0036] When preparing biochar, the sealing component 8 is first placed into the inner liner 7, and then the biomass material is placed into the inner liner 7 and the sealing component 8 is used to seal the biomass material in the inner liner 7 to prevent leakage during the process of placing it into the carbonization box 1. When adding biomass material to the inner liner 7, the same type of biomass material can be placed in all four inner liner 7 at the same time, or four different types of biomass material can be placed in at the same time for carbonization. In addition, the four inner liner 7 can carbonize three kilograms of material at a time to produce one kilogram of biochar, thus increasing the single carbonization capacity compared with the existing muffle furnace and tube furnace.

[0037] After the biomass material is prepared, open the insulation doors 2 on both sides of the carbonization box 1 and remove the sealing caps 9. Then, insert the four inner liner 7 containing the biomass material into the carbonization tubes 3 through both ends of the two carbonization tubes 3. Next, rotate the sealing assembly 8 to open the through holes on the inner liner 7. Then, put the sealing caps 9 onto the opening of the inner liner 7, so that the sealing caps 9, together with the annular plate 20, further seal the inner liner 7. Then close the insulation doors 2.

[0038] Next, the heating temperature of the electromagnetic coil 6 is set to 300 to 650 degrees Celsius by the back-end computer host, thereby instantly heating and carbonizing the biomass material in the inner liner 7. During the carbonization process, the biomass material in the inner liner 7 begins to decompose after being heated. At the same time, the biomass material releases combustible decomposition gas during the decomposition process. At this time, the decomposition gas can enter the carbonization tube 3 through the through hole at the top of the inner liner 7. Subsequently, the decomposition gas enters the flue gas combustion chamber 10 through the U-shaped pipe 4 at the top of the carbonization tube 3 and the exhaust pipe 5. At this time, the igniter 11 is turned on under the control of the computer host, thereby igniting the decomposition gas that enters the flue gas combustion chamber 10. At the same time, the intake valve 13 is also turned on under the control of the computer host, thereby providing oxygen for combustion. The exhaust heat wave generated by combustion can be discharged through the exhaust pipe 12. Since the decomposition gas can be completely burned in the flue gas combustion chamber 10 under the action of the igniter 11, the production of wood vinegar and tar during the carbonization process of biomass material is avoided, and environmental pollution is also avoided.

[0039] In addition, by installing an air intake fan 15 on the inner wall of the carbonization box 1, when the temperature sensor detects that the temperature inside the carbonization box 1 has risen to the upper limit of the protection temperature during the carbonization process of biomass materials, the heat dissipation valve is automatically opened under the operation of the computer host, and the air intake fan 15 also starts to work at the same time, thereby dissipating the heat through the heat dissipation port 16, thus cooling the carbonization box 1.

[0040] After carbonization for several minutes, the electromagnetic coil 6 is de-energized and allowed to cool naturally for 20 minutes. Wearing heat-resistant gloves, open the insulated doors 2 at both ends, remove the sealing cap 9, and rotate the sealing assembly 8 to seal the through holes on the inner liner 7. This prevents air from entering the inner liner 7 when it is removed, which could cause the biochar to spontaneously combust. Because the biomass material in the inner liner 7 is in an oxygen-free state throughout the carbonization process, the biochar produced is of extremely high quality.

[0041] Example 2:

[0042] like Figures 5 to 10As shown, the sealing assembly 8 includes a rotating shaft 801, which is inserted into the inner liner 7. A circular plate 802 is fixedly sleeved on one end of the rotating shaft 801. Sealing strips 803 are symmetrically arranged at the top and bottom of the rotating shaft 801 within the inner liner 7, and the length of the sealing strips 803 is greater than the distribution length of the multiple through holes. Multiple connecting rods 804 are vertically fixedly connected between the sealing strips 803 and the rotating shaft 801. A handle 805 is fixedly connected to the other end of the rotating shaft 801. The rotating shaft 801 is located near the handle. A sealing ring 806 is fitted onto one end of 805. A fixing rod 807 is fixedly connected to the inner side of the sealing ring 806. The fixing rod 807 is located on the diameter of the sealing ring 806 and is fixedly fitted onto the rotating shaft 801. Fan-shaped sealing plates 808 are symmetrically arranged on the front and rear sides of the fixing rod 807. The sum of the areas of the two sealing plates 808 and the fixing rod 807 is equal to the cross-sectional area of ​​the inner side of the inner liner 7. A fixing shaft 809 is fixedly connected between the opposite sides of the two sealing plates 808. The fixed shaft 809 is rotatably inserted into the fixed rod 807 in the front-to-back direction. Limiting blocks 810 are fixedly connected to the top and bottom of the sealing ring 806. Limiting grooves 811 are formed on the inner walls of the top and bottom of the inner liner 7 at positions opposite to the two limiting blocks 810. The limiting grooves 811 are parallel to the fixed rod 807, and the side of the limiting groove 811 closest to the opening of the inner liner 7 communicates with the end of the inner liner 7. The other side of the two limiting grooves 811 has the same... An annular groove 812 is provided, and the annular groove 812 is connected to the limiting groove 811. A locking component 14 is provided on the side of the sealing ring 806 near the handle 805. The sealing strip 803 is fixedly connected to the circular plate 802 on the side near the circular plate 802. The side view of the sealing plate 808 is arc-shaped, and the center of the sealing plate 808 coincides with the axis of the rotating shaft 801. The maximum distance between the two sealing strips 803 on the opposite side is equal to the diameter of the circular plate 802, and the width of the sealing plate 808 is greater than the diameter of the through hole.

[0043] The locking assembly 14 includes two L-shaped blocks 141, which are fixedly connected to the side of the sealing plate 808 near the handle 805. The top of the L-shaped block 141 protrudes beyond the top of the sealing plate 808. A section of arc-shaped protrusion 142 is fixedly connected to the side of the sealing ring 806 near the handle 805. The center of the arc-shaped protrusion 142 is the same as the center of the sealing ring 806. An arc-shaped strip 143 is slidably installed on the arc-shaped protrusion 142. The L-shaped block 141 is located between the arc-shaped strip 143 and the sealing ring 806. A lever 144 is vertically fixedly connected to the side of the arc-shaped strip 143 away from the sealing ring 806.

[0044] With the sealing assembly 8 in place, when adding biomass material to the inner liner 7, the rotating shaft 801, together with the circular plate 802, is first inserted into the inner liner 7, and the two limiting blocks 810 on the sealing ring 806 are respectively inserted into the two limiting grooves 811 on the inner wall of the inner liner 7. After the rotating shaft 801 is fully inserted into the inner liner 7, the two sealing strips 803 on the rotating shaft 801 can be supported on the inner wall of the inner liner 7, thereby making the rotating shaft 801 coincide with the axis of the inner liner 7. In addition, the sealing strip 803 opposite to the through hole can seal the through hole. The sealing plate 808 is then pressed away from the L-shaped block 141, so that the two sealing plates 808 can be deflected about the fixed shaft 809. When the sealing plate 808 is deflected by ninety degrees, the opening of the inner liner 7 is open, and biomass material can be added to the inner liner 7. Since the inner diameter of the opening of the inner liner 7 is large, the convenience of filling biomass material can be improved. During the process of adding biomass material, since the through hole is closed, the biomass material can be prevented from leaking out of the through hole.

[0045] After the biomass material is added, press the sealing plate 808 on the side near the L-shaped block 141, so that the two sealing plates 808 can be reset and cooperate with the sealing ring 806 to achieve the sealing operation of the opening of the inner liner 7. When the two L-shaped blocks 141 are close to the sealing ring 806, the lever 144 moves the arc strip 143 to move it along the arc protrusion 142 towards the L-shaped block 141. When the arc strip 143 presses down the two L-shaped blocks 141, stop moving the lever 144. At this time, the two sealing plates 808 can be locked under the restriction of the arc strip 143 on the L-shaped blocks 141, thus preventing the sealing plates 808 from being accidentally opened during the movement of the inner liner 7.

[0046] Next, the inner liner 7 containing biomass material is inserted into the carbonization tube 3. After the inner liner 7 is fully inserted into the carbonization tube 3, the shaft 801 is rotated by the handle 805. As the shaft 801 rotates, the sealing ring 806 and the two sealing plates 808 can drive the two limiting blocks 810 to rotate along the annular groove 812, while the sealing strip 803 gradually shifts away from the through hole, thus opening the through hole. This allows the pyrolysis gas generated during the carbonization of the biomass material to enter the carbonization tube 3 through the through hole, and finally enter the flue gas combustion chamber 10 through the U-shaped pipe 4 and the exhaust pipe 5 on the carbonization tube 3 for combustion. Finally, the sealing cover 9 is closed and the insulation door 2 is shut off, thus starting the carbonization of the biomass material.

[0047] After carbonization for several minutes, after the electromagnetic coil 6 is de-energized and allowed to cool naturally for 20 minutes, wear heat-resistant gloves to open the insulated door 2 at both ends, remove the sealing cover 9, and then rotate the handle 805 so that the rotating shaft 801 drives the sealing strip 803 to re-seal the through hole, thereby preventing the biochar from spontaneously combusting when the inner liner 7 is removed due to air entering the inner liner 7.

[0048] Once the biochar in the inner liner 7 has completely cooled, the handle 805 pulls the rotating shaft 801, causing it to move the circular plate 802 outward. As the circular plate 802 moves out of the inner liner 7, it can also carry the biochar out of the inner liner 7, thereby improving the biochar removal efficiency.

[0049] like Figure 7 As shown, a number of levers 17 are symmetrically fixedly connected to the top and bottom of the rotating shaft 801. A scraper 18 is fixedly connected to the side of the lever 17 away from the rotating shaft 801. The scraper 18 on the top lever 17 of the rotating shaft 801 and the scraper 18 on the bottom lever 17 of the rotating shaft 801 are rotationally symmetrical about the rotating shaft 801. A number of strip-shaped protrusions 19 are fixedly connected to the side of the sealing strip 803 close to the rotating shaft 801. One end of the strip-shaped protrusions 19 is inclined towards the sealing plate 808. The strip-shaped protrusions 19 on the two sealing strips 803 are rotationally symmetrical about the rotating shaft 801.

[0050] Since the inner liner 7 is in a vertical position when biomass material is added, the biomass material will accumulate at the end of the inner liner 7 away from the opening after the inner liner 7 is horizontally inserted into the carbonization tube 3. In addition, in order to ensure the carbonization effect, the biomass material in the inner liner 7 will not be filled completely. Therefore, when the inner liner 7 is in a horizontal position, there is a gap between the top of the biomass material and the top inner wall of the inner liner 7 in the horizontal position. At this time, the handle 805 can be held and the rotating shaft 801 can be rotated by the handle 805. As the rotating shaft 801 rotates, the two sealing strips 803 can stir the biomass material in the inner liner 7. During the stirring process, the strip-shaped protrusions 19 on the sealing strips 803 can push the biomass material accumulated at the end of the inner liner 7 away from the opening towards the opening of the inner liner 7, so that the biomass material in the inner liner 7 is more evenly distributed, thereby improving the carbonization efficiency and carbonization effect of the biomass material.

[0051] Furthermore, by providing a deflector plate 17, after the biomass material in the inner liner 7 is roughly evenly distributed by the strip-shaped protrusions 19, the handle 805 drives the rotating shaft 801 to rotate towards the scraper plate 18, thereby turning the deflector plate 17, which was originally in a vertical state, into a horizontal state. As the deflector plate 17 gradually turns into a horizontal state, the scraper plate 18 can scoop some of the biomass material to the top of the horizontal deflector plate 17, thereby making the biomass material in the inner liner 7 distributed vertically, reducing the thickness of the biomass material during carbonization, and further improving the carbonization efficiency of the biomass material in the subsequent carbonization process.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
