Description

A system for recycling waste gas and waste heat in the process of preparing carbon sources from kitchen waste Technical Field

[0001] The present invention relates to the technical field of carbon source preparation, and in particular to a system for recycling waste heat from waste gas during the preparation of carbon sources from kitchen waste. Background Art

[0002] Food waste can be converted into a carbon source for wastewater treatment, namely leachate, through hydrothermal liquefaction or fermentation to produce lactic acid and reducing sugars, and hydrothermal carbonization to produce functional carbon materials. A screw extruder processes the food waste to produce solid and liquid phases. The solid phase is then removed from the solid phase and heated in a digester.

[0003] The carbonization technology of food waste can be divided into three categories: physical method, chemical method and biological method. The physical method mainly includes processes such as pressing, drying, crushing and separation. Its advantages are simple and efficient treatment process, and the ability to significantly reduce the moisture content of food waste through heating devices. Hot steam is generated during the drying process. It is a high-temperature and smelly waste gas. The waste gas needs to be deodorized and the waste heat recovered before being discharged to the outside. Common drying methods include heating block drying and hot air drying. During the drying process, hot air will be continuously discharged to the outside. The air flow contains heat and odor. If it is discharged directly into the air, it will lead to a waste of heat resources. The odor will also pollute the air, causing the air to be full of the odor of garbage.

[0004] In the existing waste gas waste heat recycling system, the odorous air flow containing heat is first passed through the heat exchanger to recover the heat in the waste gas, and then a spray reaction liquid is used to react with the odorous air flow to remove part of the odor. Finally, the air flow is passed through the packing to react and remove water vapor and remaining odor in the air flow. The waste gas enters from the bottom of the packing and flows out from the top of the packing. This will cause the packing below to absorb more water vapor and odor than the packing above. When the packing below reaches the maximum absorption capacity, all the packing needs to be replaced, resulting in a low utilization rate of the upper packing, causing waste of resources and manpower.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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.

[0045] Referring to Figures 1-7, the present invention provides a technical solution: a system for recycling waste heat from waste gas during the preparation of a carbon source from food waste, comprising a cylinder 1; and a reaction chamber 2, wherein the reaction chamber 2 is located on the inner wall of the cylinder 1. A filling cylinder 3, a liquid outlet pipe 4, and a rotating shaft 5 are concentrically arranged within the reaction chamber 2. The outer wall of the liquid outlet pipe 4 is provided with a plurality of nozzles, through which a reaction liquid is sprayed downwardly, and the reaction liquid reacts with an upwardly drifting odorous airflow. A motor 6 is provided at the bottom of the cylinder 1, which drives the rotating shaft 5 to rotate.

[0046] And, a barrier assembly, the barrier assembly is located on the inner wall of the filling cylinder 3, several of the barrier assemblies are arranged longitudinally, and the center of the barrier assembly is rotatably connected to the rotating shaft 5; several barrier assemblies separate the inner wall of the filling cylinder 3 into several filling cavities, each of which is filled with filler, which is particulate matter, and the several filling cavities are marked from bottom to top as filling cavity one, filling cavity two, filling cavity three and filling cavity four.

[0047] The baffle assembly includes a baffle 1 7 and a baffle 2 10. The baffle 1 7 is fixedly mounted on the inner wall of the filling cylinder 3. A cavity 8 is provided inside the baffle 1 7. An opening 9 is provided on the inner wall of the baffle 1 7 and is connected to the inner wall of the filling cylinder 3. A baffle 2 10 is slidably mounted on the inner wall of the cavity 8. The opening 9 is closed or opened by the baffle 2 10. The outer edge of the baffle 1 7 is high and the inner edge is low. When the opening 9 is opened, the filler in the corresponding filling cavity will flow downward.

[0048] Several barrier assemblies are marked from bottom to top as the first barrier assembly, the second barrier assembly, the third barrier assembly, and the fourth barrier assembly. When the opening 9 of the first barrier assembly is opened, the particles in the filling chamber 1 are discharged downward through the discharge pipe 15. At this time, the discharge port 20 of the discharge pipe 15 is closed by the baffle 18, and the particles will accumulate in the discharge pipe 15. The capacity of the discharge pipe 15 is just equal to the capacity of the filling chamber 1. By cooperating with the clamping assembly and the transmission assembly, the second opening 9, the third opening 9 and the fourth opening 9 are opened in sequence, so that the particles in the second filling chamber fall into the first filling chamber, the particles in the third filling chamber fall into the second filling chamber, the particles in the fourth filling chamber fall into the third filling chamber, and the particles in the material box 16 fall into the fourth filling chamber. The position of the particles in the filling cylinder 3 can be adjusted so that the particles move downward in the filling cylinder 3 in sequence, and the particles in the filling cylinder 3 are moved to the lowermost end of the filling cylinder 3 in sequence, so that the particles in the filling cylinder 3 are evenly contacted with the airflow, thereby improving the utilization rate of the particles. Then, the rotating shaft 5 rotates counterclockwise, driving the partition 2 10 to close the opening 9, and the electric push rod 19 extends to drive the baffle 18 to move upward to separate from the discharge port 20 of the discharge pipe 15, thereby discharging the ineffective particles in the reaction discharge pipe 15. The particle loss rate at the bottom of the filling cylinder 3 is higher and the particle loss at the top of the filling cylinder 3 is lower. The particles at the bottom of the filling cylinder 3 can be accurately separated, and the particles at the bottom of the filling cylinder 3 can be replenished in time, and the particles in the filling cylinder 3 can be filled at a specific position.

[0049] As well as a clamping assembly and a transmission assembly, the clamping assembly is located on the inner wall of the partition 2 10, the transmission assembly is located on the outer wall of the rotating shaft 5, the clamping assembly extends into the cavity 8, and the clamping assembly is driven to rotate by the transmission assembly.

[0050] The output shaft of the motor 6 is fixedly connected to the bottom end of the rotating shaft 5, the top end of the rotating shaft 5 extends to the top of the filling cylinder 3, the inner wall of the partition 2 10 is slidingly connected to the rotating shaft 5 through a slider 11, and the outer wall of the partition 2 10 is slidingly connected to the filling cylinder 3 through a slider 2 12.

[0051] Figure 8, the cavity 8 includes a rotating groove 1 80, a rotating groove 2 81, a limiting groove 1 82, a limiting groove 2 83 and a receiving groove 84 that are connected to each other. The openings 9 are arranged clockwise from bottom to top. The partition 2 10 is slidingly connected to the receiving groove 84. The limiting groove 1 82 is located on one side of the opening 9, and the limiting groove 2 83 is located on the other side of the opening 9. The height of the limiting groove 1 82 is less than the height of the limiting groove 2 83.

[0052] 9-13 , the snap-fit ​​assembly includes a groove 100 , a spring 101 and an insert 102 . The groove 100 is provided on the inner wall of the partition 2 10 . The inner wall of the groove 100 is connected to the insert 102 via the spring 101 . The insert 102 is slidably connected to the groove 100 .

[0053] When the spring 101 is in a balanced state, the insert 102 extends into the limiting groove 83, and the opening 9 is closed by the partition 10. When the spring 101 is in a squeezed state, the insert 102 extends into the limiting groove 82, and the opening 9 is opened.

[0054] The connecting assembly includes a power rod 50, a rotating shaft 51 and a power plate 52. The power rod 50 is fixed to the outer wall of the rotating shaft 5, and the power rod 50 pushes the plug 102 to rotate clockwise. The outer wall of the power rod 50 is connected to the power plate 52 through the rotating shaft 51, and the power plate 52 pushes the plug 102 to rotate counterclockwise. The rotating shaft 51 is located in the middle or top of the power plate 52. The outer wall of the rotating shaft 5 is provided with a stirring rod 53 above the partition 1 7. A stirring rod 53 is provided in each filling chamber 1, filling chamber 2, filling chamber 3 and filling chamber 4, and the stirring rod 53 can rotate in the filling chamber. When the rotating shaft 5 rotates, the stirring rod 53 is driven to rotate, thereby changing the position of the particles in the filling chamber; when loading, the particles are prevented from accumulating below the opening 9, and when discharging, the particles in the filling chamber are promoted to reach the opening 9, thereby being discharged to the outside. The power rod 50 is located in the rotating groove 1 80, the power plate 52 is located in the rotating groove 2 81, and the top of the insert 102 is provided with an inclined surface 103 and a straight surface 104. A feed pipe 14 and a discharge pipe 15 are provided through the inner wall of the cylinder body 1. The feed pipe 14 is connected to the top of the filling cylinder 3, and the discharge pipe 15 is connected to the lowermost opening 9. The outer ends of the feed pipe 14 and the discharge pipe 15 are respectively provided with a material box 16 and a material box 2 17. The inner wall of the material box 2 17 is plugged with a baffle 18. The outer wall of the material box 2 17 is provided with an electric push rod 19. The telescopic end of the electric push rod 19 is fixedly connected to the baffle 18. The baffle 18 is used to open or close the discharge port 20 of the discharge pipe 15. The filling cylinder 3, the feed pipe 14, the discharge pipe 15 and the baffle assembly are all provided with a plurality of through holes to facilitate the airflow to flow upward through the through holes.

[0055] Since the openings 9 are arranged clockwise from bottom to top, and the power rods 50 are on the same vertical line, the power rods 50 will contact the corresponding inserts 102 one by one from bottom to top.

[0056] The rotating shaft 5 drives the power rod 50 to rotate clockwise. At this time, the power rod 50 contacts the straight surface 104 of the insert block 102. The power rod 50 pushes the insert block 102 clockwise, and the insert block 102 drives the partition plate 2 10 to rotate clockwise synchronously. The partition plate 2 10 gradually enters the storage groove 84. Since the lowest end of the inclined surface 103 is lower than the highest end of the limiting groove 1 82, when the inclined surface 103 of the insert block 102 contacts the limiting groove 1 82, the inclined surface 103 of the insert block 102 will be blocked by the partition plate 1 7. The power rod 50 continues to push the insert block 102 clockwise. Under the guidance of the inclined surface 103, the insert block 102 moves downward while entering the limiting groove 1 82. During the downward movement of the insert block 102, the spring 101 is squeezed until the highest point of the insert block 102 is lower than the power rod 50.

[0057] Then, the power rod 50 continues to rotate clockwise, and the power rod 50 will always drive the power plate 52 to rotate synchronously during the rotation process. At this time, the power rod 50 can no longer push the plug block 102 clockwise, and the power rod 50 passes through the plug block 102 from above the plug block 102. When the power plate 52 passes through the plug block 102, it is blocked by the plug block 102, and the power plate 52 will rotate upward. The power plate 52 rotates from a vertical position to an inclined position. The power plate 52 rotates into the rotating groove 2 81 in the inclined state and passes through the plug block 102 from above the plug block 102. After the power plate 52 and the plug block 102 are staggered, the bottom of the power plate 52 loses the obstruction of the plug block 102. Under the action of the gravity of the power plate 52, the power rod 50 rotates downward to reset, and the power plate 52 returns to the vertical state.

[0058] In Figures 14 and 15, the cylinder body 1 includes an inner cylinder 110, an outer cylinder 111, a plug-in plate 112, an odorous air duct 113, a clean air duct 114, an air storage box 115, an air inlet pipe 116 and an air collecting cover 117. A heat transfer cavity is provided between the inner cylinder 110 and the outer cylinder 111. A plurality of plug-in plates 112 are plugged into the inner wall of the heat transfer cavity. The inner wall of the outer cylinder 111 is provided with a plurality of groups of slots. The plug-in plates 112 are plugged into the slots. The heat transfer cavity is divided into the odorous air duct 113 and the clean air duct 114 by the plug-in plates 112. 14. The bottom of the odorous air duct 113 is connected to the inner wall of the inner cylinder 110. The outer wall of the outer cylinder 111 is fixedly provided with an air storage box 115. The interior of the air storage box 115 is connected to the clean air duct 114. The top of the odorous air duct 113 is provided with an air inlet pipe 116. The top of the inner cylinder 110 is fixedly provided with an air collecting hood 117. The top of the air collecting hood 117 is connected to the air storage box 115 through a return pipe 118. The top of the outer cylinder 111 is provided with an air outlet 119.

[0059] The inner cylinder 110 is located at the top of the outer cylinder 111 , the liquid outlet pipe 4 is located in the middle of the inner cylinder 110 , the filling cylinder 3 is located at the top of the inner cylinder 110 , and the bottom of the outer cylinder 111 is a liquid collecting portion.

[0060] The specific implementation is as follows: when in use, several barrier assemblies separate the inner wall of the filling cylinder 3 into several filling cavities, each of which is filled with filler, which is particulate matter, and the several filling cavities are marked from bottom to top as filling cavity one, filling cavity two, filling cavity three and filling cavity four; several barrier assemblies are marked from bottom to top as the first barrier assembly, the second barrier assembly, the third barrier assembly and the fourth barrier assembly; in the initial state, the electric push rod 19 is in a retracted state, the baffle 18 blocks the discharge port 20 of the discharge pipe 15, and the discharge port 20 of the discharge pipe 15 is closed.

[0061] Step 1: Open the first opening 9: The output shaft of the motor 6 drives the rotating shaft 5 to rotate clockwise. In the first baffle assembly, the rotating shaft 5 drives the power rod 50 to rotate clockwise. At this time, the power rod 50 contacts the straight surface 104 of the insert block 102. The power rod 50 pushes the insert block 102 clockwise, and the insert block 102 drives the second partition 10 to rotate clockwise synchronously. The second partition 10 gradually enters the receiving groove 84, and the opening 9 is gradually opened. The particles in the filling chamber 1 fall into the discharge pipe 15 through the opening 9;

[0062] Because the lowest end of the inclined surface 103 is lower than the highest end of the limiting groove 1 82, when the inclined surface 103 of the insert block 102 contacts the limiting groove 1 82, the inclined surface 103 of the insert block 102 is blocked by the partition 1 7. The power rod 50 continues to push the insert block 102 clockwise. Under the guidance of the inclined surface 103, the insert block 102 moves downward while entering the limiting groove 1 82. During the downward movement of the insert block 102, the spring 101 is compressed until the highest point of the insert block 102 is lower than the power rod 50. At this time, a gap is left between the lowest point of the inclined surface 103 and the upper surface of the partition 2 10.

[0063] Then, the power rod 50 continues to rotate clockwise, and the power rod 50 will always drive the power plate 52 to rotate synchronously during the rotation process. At this time, the power rod 50 can no longer push the plug block 102 clockwise, and the power rod 50 passes the plug block 102 from above the plug block 102. When the power plate 52 passes the plug block 102, it is blocked by the plug block 102, and the power plate 52 will rotate upward, and the power plate 52 rotates from the vertical to the inclined position. The power plate 52 rotates into the second rotation slot 81 in the inclined state and passes the plug block 102 from above the plug block 102. After the power plate 52 and the plug block 102 are staggered, the bottom of the power plate 52 loses the obstruction of the plug block 102. Under the action of the self-gravity of the power plate 52, the power rod 50 rotates downward to reset, and the power plate 52 returns to the vertical state, which is marked here as the first power rod 50 and the first power plate 52.

[0064] Step 2: Open the second opening 9: The output shaft of the motor 6 continues to drive the rotating shaft 5 to rotate clockwise. Similarly, in the second baffle assembly, the opening 9 is opened, and the particles in the filling chamber 2 fall into the filling chamber 1 through the opening 9, which is marked as the second power rod 50 and the second power plate 52;

[0065] Step 3: Open the third opening 9: The output shaft of the motor 6 continues to drive the rotating shaft 5 to rotate clockwise. Similarly, in the third baffle assembly, the opening 9 is opened, and the particles in the filling chamber 3 fall into the filling chamber 2 through the opening 9, which is marked as the third power rod 50 and the third power plate 52;

[0066] Step 4: Open the fourth opening 9: The output shaft of the motor 6 continues to drive the rotating shaft 5 to rotate clockwise. Similarly, in the fourth baffle assembly, the opening 9 is opened, and the particles in the filling chamber 4 fall into the filling chamber 3 through the opening 9, which is marked here as the fourth power rod 50 and the fourth power plate 52. At this time, the space in the filling chamber 4 is vacated, and the particles in the material box 16 fall into the filling chamber 4 through the feeding pipe 14, thereby replenishing new particles into the filling cylinder 3. When this step is completed, the output shaft of the motor 6 has made a complete clockwise rotation.

[0067] After the cam 102 is in the stop groove 83, the motor 6 stops rotating, and the output shaft of the motor 6 rotates clockwise, and the rotating shaft 5 drives the power rod 50 and the power plate 52 to rotate counterclockwise synchronously. When the power plate 52 reaches the limit groove 1 82, there is a gap between the lowest point of the inclined surface 103 and the upper surface of the partition plate 2 10 in the limit groove 1 82. The power rod 50 blocks the counterclockwise rotating power plate 52. At this time, the power plate 52 is located on the side of the plug block 102 close to the lowest point of the inclined surface 103. The power plate 52 can use the above gap to push the plug block 102 to rotate counterclockwise until the plug block 102 enters the limit groove 2 83 and the motor 6 stops rotating after reset. Then the output shaft of the motor 6 rotates clockwise, and the rotating shaft 5 drives the power rod 50 and the power plate 52 to disengage from the plug block 102 until the power rod 50 and the power plate 52 rotate to the side of the plug block 102 with the straight surface 104 again, completing the reset.

[0068] Step 6: Deodorizing the waste gas: The operation of the heating device in the food waste treatment process generates waste gas with a foul odor. The waste gas with a foul odor enters the odor flow channel 113 through the air inlet pipe 116, flows downward along the odor flow channel 113, and is finally discharged from the bottom end of the odor flow channel 113 to the bottom of the outer cylinder 111. The opening 9 of the odor flow channel 113 is downward, and the waste gas will impact downward for a distance under the action of inertia, thereby extending the residence time of the waste gas in the reaction chamber 2, increasing the reaction time between the waste gas and the spray liquid, and improving the effect of waste gas treatment. After the reaction, the clean air flow floats upward through the filling cylinder 3 and reacts with the particulate matter in the filling cylinder 3.

[0069] Step seven, waste heat recycling; the clean airflow passes through the air collecting hood 117 and the return pipe 118 into the air storage box 115, and then enters the clean air flow duct 114 from the air storage box 115. The clean airflow enters from the bottom of the clean air flow duct 114 and flows upward along the clean air flow duct 114. Because the clean air flow duct 114 and the odorous air flow duct 113 are arranged alternately, heat exchange is performed in the process of the odorous waste gas flowing downward and the clean air flow flowing upward, thereby transferring the heat in the waste gas to the clean airflow. When the clean airflow reaches the top of the clean airflow duct 114, the clean airflow already has heat. Because the air outlet 119 is connected to the heating device in the food waste treatment through an external pipe, the clean airflow containing heat flows back to the heating device from the air outlet 119, thereby realizing the recycling of the waste gas.
