The device includes a support frame, a pyrolysis furnace mounted on the support frame, a combustion furnace positioned above the pyrolysis furnace, a first valve connected to a first pipe, and a movable block for opening or closing the first pipe within the first valve. A second valve, identical to the first valve, is mounted on a second pipe and includes a movable block for unblocking the second pipe.

Description

Technical Field

[0001] This invention relates to the field of waste treatment equipment technology, specifically a high-temperature pyrolysis device for municipal solid waste treatment. Background Technology

[0002] High-temperature pyrolysis technology for municipal solid waste decomposes waste into a series of combustible gases, such as methane, hydrogen, and carbon monoxide, in a low-temperature decomposition furnace. These combustible gases are then piped into a combustion furnace where they are burned. The heat released from the combustion is then piped back into the decomposition furnace to heat the waste. No additional fuel is needed in this process, thus achieving waste-to-waste treatment. Compared to directly incinerating waste, dioxin emissions are significantly reduced after high-temperature pyrolysis.

[0003] Existing high-temperature pyrolysis equipment for municipal solid waste treatment produces combustible gases with high carbon content in the decomposition furnace. This can easily lead to carbon buildup in the pipes connecting the decomposition furnace and the combustion furnace, causing blockages and hindering gas circulation between them. Consequently, the gases cannot burn completely, resulting in high dioxin levels in the emissions, which is not environmentally friendly. Therefore, this equipment does not meet current requirements. To address this, we propose a new high-temperature pyrolysis device for municipal solid waste treatment. Summary of the Invention

[0004] This invention provides a high-temperature pyrolysis device for municipal solid waste treatment. It features bidirectional gas circulation in the pipeline between the decomposition furnace and the combustion furnace. The circulating gas effectively oxidizes carbon deposits in the pipeline, preventing blockages and facilitating gas circulation between the two furnaces. This results in lower dioxin levels in the emitted gases, making it more environmentally friendly. This invention addresses the problem mentioned in the background section of existing high-temperature pyrolysis devices for municipal solid waste treatment, where the combustible gases produced during waste decomposition in the decomposition furnace have a high carbon content, easily causing carbon buildup in the pipeline connecting the decomposition furnace and the combustion furnace, leading to blockages and hindering gas circulation. This results in incomplete combustion, higher dioxin levels in the emitted gases, and a less environmentally friendly outcome.

[0005] The present invention provides the following technical solution: a high-temperature pyrolysis device for municipal solid waste treatment, comprising a support frame, a pyrolysis furnace mounted on the support frame, a combustion furnace disposed above the pyrolysis furnace, a first pipe and a second pipe connected between the combustion furnace and the pyrolysis furnace, a motor mounted on the support frame, a rotating shaft mounted on the motor, a plurality of stirring rods for stirring the waste mounted on the rotating shaft, a first valve disposed on the first pipe, the first valve being configured as a tee pipe, the first valve communicating with the first pipe, and a first movable block disposed in the first valve for opening or closing the first pipe;

A compression spring is provided in the first sleeve, and one end of the compression spring abuts against the first moving plate.

[0014] A second reset mechanism is installed at one end of the second moving rod, and the second reset mechanism is configured the same as the first reset mechanism.

[0015] As an optional solution for a high-temperature pyrolysis device for municipal solid waste treatment according to the present invention, a second sleeve is installed on both the first moving rod and the second moving rod, and a first pull rod is installed at one end of both the first moving block and the second moving block. The first pull rod is slidably installed in the second sleeve, and a first tension spring is provided in the second sleeve. One end of the first tension spring is fixedly connected to the first pull rod.

[0016] As an optional solution for a high-temperature pyrolysis device for municipal solid waste treatment according to the present invention, a third pipe is installed on the combustion furnace. The third pipe is installed in the middle of the combustion furnace along its length, and one end of the third pipe is connected to the pyrolysis furnace.

[0017] The third pipe opens when the first pipe and the second pipe are closed simultaneously.

[0018] As an optional solution for a high-temperature pyrolysis device for municipal solid waste treatment according to the present invention, a third valve and a fourth valve are installed on the third pipeline, and the third valve and the fourth valve are configured the same as the first valve.

[0019] The third valve is located on the third pipeline on the side adjacent to the first reset mechanism. A third moving block is installed in the third valve. A third moving rod is installed on one side of the third moving block. The third moving rod passes through the first sleeve, and one end of the third moving rod is fixedly installed on the first moving plate.

[0020] The second reset mechanism includes a third sleeve and a second moving plate. The third sleeve is configured the same as the first sleeve, and the second moving plate is configured the same as the first moving plate.

[0021] The fourth valve is located on the third pipe on the side adjacent to the second reset mechanism. The fourth valve is equipped with a fourth moving block, and a fourth moving rod is installed on one side of the fourth moving block. The fourth moving rod passes through the third sleeve, and one end of the fourth moving rod is fixedly installed on the second moving plate.

[0022] As an alternative solution to the high-temperature pyrolysis equipment for municipal solid waste treatment described in this invention, one end of the third pipe is installed at the bottom of the pyrolysis furnace, and multiple fourth pipes are installed on the third pipe. The multiple fourth pipes are vertically arranged and evenly distributed along the length of the pyrolysis furnace.

[0023] As an alternative solution to the high-temperature pyrolysis equipment for municipal solid waste treatment described in this invention, a movable sleeve is slidably installed on the fourth pipe, the movable sleeve slidably passes through the pyrolysis furnace, a movable plate is installed at the bottom of the movable sleeve, a fixed plate is installed on the fourth pipe, a second tension spring is installed on the fixed plate, one end of the second tension spring is fixedly connected to the movable plate, and the second tension spring is located outside the pyrolysis furnace.

[0024] The movable sleeve has a slot for outputting hot air, and a push plate for lifting solid waste is installed at the top of the movable sleeve. A vertical plate is installed on the push plate, and an arc-shaped plate is installed on the vertical plate. A lifting rod is installed on the stirring rod, and the lifting rod slides in contact with the arc-shaped plate.

[0025] When the third pipe is opened, the lifting rod lifts the push plate through the arc-shaped plate.

[0026] The present invention has the following beneficial effects:

[0027] 1. This high-temperature pyrolysis equipment for municipal solid waste treatment, when the rotating rod rotates, will intermittently mesh with the first gear and the second gear and the second rack. When the first gear and the first rack are meshed, the second gear and the second rack are not meshed. At this time, the first moving rod drives the first moving block to move to the outside of the first valve, opening the first pipe and opening the one-way valve on the second moving block. Similarly, when the first gear and the first rack are not meshed, and the second gear and the second rack are meshed, the first pipe is closed and the one-way valve on the first moving block is opened. This allows the gas in the first and second pipes to flow bidirectionally intermittently, enabling bidirectional circulation of the gas flow between the combustion furnace and the pyrolysis furnace. The high-temperature gas from the combustion furnace can oxidize and remove the carbon deposits generated in the first and second pipes, thus preventing blockage of either pipe. This facilitates full circulation of gas between the first and second pipes, allowing for the full decomposition of gases produced during waste decomposition, reducing the dioxin content in the emitted gases, and making the system more environmentally friendly.

[0028] 2. This high-temperature pyrolysis equipment for municipal solid waste treatment, when the first and second valves are closed simultaneously, moves the first moving rod to one side via the first moving plate, and the second moving rod to one side via the second moving plate, thereby opening the third and fourth valves simultaneously. Gas from the combustion furnace enters the pyrolysis furnace through the third pipe, which is located in the middle of the combustion furnace. During the period when the third and fourth valves are closed simultaneously, the third pipe provides a heat source for auxiliary heating of the gas entering the pyrolysis furnace. Furthermore, fully combusted gas from the combustion furnace enters the pyrolysis furnace, preventing gas from entering the pyrolysis furnace without complete combustion during the alternating opening and closing of the first and second pipes, thus improving the reliability of the device.

[0029] 3. The high-temperature pyrolysis equipment for municipal solid waste treatment has a fourth pipe that is evenly arranged along the length of the pyrolysis furnace to heat the bottom of the solid waste in the pyrolysis furnace, thereby rapidly decomposing the solid waste. In addition, a movable sleeve is slidably installed on the fourth pipe. When the third pipe is opened, gas enters the pyrolysis furnace through the through-slot. Furthermore, a push plate is installed at the top of the movable sleeve. When the push plate moves upward, it pushes up the solid waste around the through-slot to prevent the solid waste from clogging the through-slot. Attached Figure Description

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1: This example aims to address the problem of existing high-temperature pyrolysis equipment for municipal solid waste treatment. The combustible gases produced during waste decomposition in the decomposition furnace have a high carbon content, easily causing carbon buildup in the pipes connecting the decomposition furnace and the combustion furnace, leading to pipe blockage. This hinders gas circulation between the decomposition furnace and the combustion furnace, resulting in incomplete combustion and high dioxin levels in the emitted gases, which is environmentally unfriendly. Please refer to [link to relevant documentation]. Figures 1 to 10A high-temperature pyrolysis device for municipal solid waste treatment includes a support frame 107, on which a pyrolysis furnace 103 is mounted. A combustion furnace 102 is positioned above the pyrolysis furnace 103. A first pipe 105 is installed at one end of the combustion furnace 102, and a second pipe 106 is installed at the other end of the combustion furnace 102. The first pipe 105 and the second pipe 106 are respectively connected to the pyrolysis furnace 103. A motor 101 is also mounted on the support frame 107. A rotating shaft 108 is mounted on the motor 101. Multiple stirring rods 109 for stirring the waste are mounted on the rotating shaft 108. It should be noted that a blower for supplementing oxygen is provided on the combustion furnace 102. A pressure relief valve (not shown in the figure) is also provided on the combustion furnace 102 to prevent excessive pressure. The blower and the pressure relief valve are existing technologies in the field and will not be described in detail here.

[0043] Please refer to the following: Figure 1 , Figure 5 A first valve 201 is installed on the first pipe 105. The first valve 201 is a tee pipe and is connected to the first pipe 105. The first valve 201 has a first moving block 213 for opening or closing the first pipe 105. A second valve 226 is installed on the second pipe 106. The second valve 226 is the same as the first valve 201. The second valve 226 has a second moving block 218 for controlling the opening and closing of the second pipe 106. Both the moving block 218 and the first moving block 213 are provided with through holes 224. A one-way valve 225 is provided in the through hole 224. The one-way valve 225 only allows gas to enter the combustion furnace 102 from the pyrolysis furnace 103 in one direction. It should be noted that the one-way valve 225 includes a baffle hinged in the through hole 224. A tension spring is provided on the side of the baffle. The baffle can only deflect in one direction, so that the gas can only pass through in one direction. The specific structure and principle of the one-way valve 225 are well known to those skilled in the art and will not be described in detail here.

[0044] For details, please refer to Figure 3 , Figure 4 The first valve 201 and the second valve 226 are opened alternately. When the first valve 201 is open, the one-way valve 225 on the second moving block 218 is opened, and the high-temperature gas in the combustion furnace 102 enters the pyrolysis furnace 103 through the first pipe 105. The combustible gas in the pyrolysis furnace 103 enters the combustion furnace 102 through the second pipe 106 and the one-way valve 225 on the second moving block 218. Conversely, when the second valve 226 is open, the one-way valve 225 on the first moving block 213 is opened, and the high-temperature gas in the combustion furnace 102 enters the pyrolysis furnace 103 through the second pipe 106. At this time, the combustible gas entering the pyrolysis furnace 103 enters the combustion furnace 102 through the first pipe 105 and the one-way valve 225 on the first moving block 213.

[0045] Please refer to the following: Figure 4 , Figure 5 One end of the first moving block 213 is equipped with a first moving rod 202, and a first rack 212 is provided on the first moving rod 202. A fixed block 208 is installed on the pyrolysis furnace 103, and a rotating rod 209 is rotatably installed on the fixed block 208. The rotating rod 209 is connected to the motor 101 for transmission. A first gear 211 is provided on the rotating rod 209, and the first gear 211 and the first rack 212 mesh intermittently.

[0046] Please refer to the following: Figure 7 , Figure 8 A second moving rod 219 is installed at one end of the second moving block 218. A second rack 221 is provided on the second moving rod 219. A second gear 220 is provided on the rotating rod 209. The second gear 220 and the second rack 221 mesh intermittently. The first gear 211 and the second gear 220 are set as incomplete gears. When the first gear 211 meshes with the first rack 212, the second gear 220 and the second rack 221 do not mesh.

[0047] For details, please refer to Figure 1 A flange 203 is provided on the rotating shaft 108. A first roller 204 with a groove is detachably installed on the flange 203 by bolts and nuts. A second roller 206 with a groove is installed on one end of the rotating rod 209. A belt 205 is provided on the second roller 206. One end of the belt 205 is installed on the first roller 204.

[0048] Additionally, please refer to the following: Figure 5 , Figure 6 One end of the first moving rod 202 is provided with a first reset mechanism 2200 for resetting the first moving rod 202. The first reset mechanism 2200 includes a first sleeve 210, in which a first moving plate 223 is slidably installed. The first moving plate 223 is fixedly connected to the first moving rod 202. A compression spring 217 is provided in the first sleeve 210, and one end of the compression spring 217 abuts against the first moving plate 223. One end of the second moving rod 219 is provided with a second reset mechanism 2400, which is the same as the first reset mechanism 2200.

[0049] Additionally, please refer to Figure 5 A second sleeve 216 is installed on both the first moving rod 202 and the second moving rod 219. A first pull rod 214 is installed on one end of both the first moving block 213 and the second moving block 218. The first pull rod 214 is slidably installed in the second sleeve 216. A first tension spring 215 is provided in the second sleeve 216. One end of the first tension spring 215 is fixedly connected to the first pull rod 214.

[0050] It should be noted that the design of the second sleeve 216 and the first pull rod 214 helps to extend the opening time of the first valve 201 or the second valve 226. Specifically, when the first gear 211 meshes with the first rack 212, the first moving rod 202 pulls the first moving block 213 through the first tension spring 215, thereby opening the first valve 201 or the second valve 226. At this time, the first gear 211 and the first rack 212 are still meshed, while the first moving block 213 stops moving. The first tension spring 215 is stretched under the action of the first moving rod 202, thereby extending the opening time of the first valve 201 or the second valve 226.

[0051] In this embodiment: As the motor 101 operates, the motor 101 drives the second roller 206 to rotate via the first roller 204, further driving the rotating rod 209 to rotate. When the rotating rod 209 rotates, the first gear 211 intermittently meshes with the first rack 212, and the second gear 220 intermittently meshes with the second rack 221. When the first gear 211 meshes with the first rack 212, the second gear 220 does not mesh with the second rack 221. At this time, the first moving rod 2... 02 drives the first moving block 213 to move outside the first valve 201, opening the first pipe 105 and the one-way valve 225 on the second moving block 218. High-temperature gas in the combustion furnace 102 enters the pyrolysis furnace 103 through the first pipe 105, and combustible gas in the pyrolysis furnace 103 enters the combustion furnace 102 through the second pipe 106 and the one-way valve 225 on the second moving block 218. Similarly, when the first gear 211 and the first rack 212 are not meshed, and the second gear... When 220 meshes with the second rack 221, the first pipe 105 is closed, and the one-way valve 225 on the first moving block 213 is opened. The high-temperature gas in the combustion furnace 102 enters the pyrolysis furnace 103 through the second pipe 106. At this time, the combustible gas entering the pyrolysis furnace 103 enters the combustion furnace 102 through the first pipe 105 and the one-way valve 225 on the first moving block 213. This enables the gas in the first pipe 105 and the second pipe 106 to flow bidirectionally intermittently, allowing the airflow to circulate bidirectionally between the combustion furnace 102 and the pyrolysis furnace 103. The high-temperature gas coming out of the combustion furnace 102 can oxidize and remove the carbon deposits generated in the first pipe 105 and the second pipe 106, thereby preventing the first pipe 105 or the second pipe 106 from being blocked. This facilitates the full circulation of gas between the first pipe 105 and the second pipe 106, allowing the gas generated by waste decomposition to be fully decomposed, reducing the dioxin content in the emitted gas, and thus making it more environmentally friendly.

[0052] Example 2 aims to address the problem that when the first pipe 105 and the second pipe 106 are alternately opened, the gas that has just entered the combustion furnace 102 immediately returns to the pyrolysis furnace 103, resulting in incomplete combustion of the circulating gas. This example is an improvement upon Example 1. For details, please refer to [link to example 1]. Figures 1 to 10 A third pipe 301 is installed on the combustion furnace 102. The third pipe 301 is installed in the middle of the combustion furnace 102 along its length. The other end of the third pipe 301 is connected to the pyrolysis furnace 103. When the first pipe 105 and the second pipe 106 are closed at the same time, the third pipe 301 is opened.

[0053] For details, please refer to Figure 3 , Figure 6 A third valve 309 and a fourth valve 310 are installed on the third pipe 301. The third valve 309 and the fourth valve 310 are set in the same way as the first valve 201. The third valve 309 is set on the third pipe 301 on the side adjacent to the first reset mechanism 2200. A third moving block 318 is installed in the third valve 309. A third moving rod 307 is installed on one side of the third moving block 318. The third moving rod 307 passes through the first sleeve 210, and one end of the third moving rod 307 is fixedly installed on the first moving plate 223.

[0054] Additionally, please refer to Figure 7 , Figure 8 The second reset mechanism 2400 includes a third sleeve 207 and a second moving plate 222. The third sleeve 207 is configured the same as the first sleeve 210, and the second moving plate 222 is configured the same as the first moving plate 223. The fourth valve 310 is located on the third pipe 301 on one side adjacent to the second reset mechanism 2400. A fourth moving block 319 is installed in the fourth valve 310. A fourth moving rod 304 is installed on one side of the fourth moving block 319. The fourth moving rod 304 passes through the third sleeve 207, and one end of the fourth moving rod 304 is fixedly installed on the second moving plate 222.

[0055] In this embodiment: A third pipe 301 is installed on the combustion furnace 102. When the first valve 201 and the second valve 226 are closed simultaneously, the first moving rod 202 drives the third moving rod 307 to one side through the first moving plate 223, and the second moving rod 219 drives the fourth moving rod 304 to one side through the second moving plate 222. This causes the third valve 309 and the fourth valve 310 to open simultaneously, and the gas in the combustion furnace 102 enters the pyrolysis furnace 103 through the third pipe 301. Moreover, the third pipe 301 is located in the middle of the combustion furnace 102. During the period when the third valve 309 and the fourth valve 310 are closed simultaneously, the third pipe 301 provides a heat source for auxiliary heating to the gas entering the pyrolysis furnace 103. In addition, the gas that has been fully combusted in the combustion furnace 102 enters the pyrolysis furnace 103, preventing the gas from entering the pyrolysis furnace 103 without being fully combusted during the intervals between the alternating opening of the first pipe 105 and the second pipe 106, thus improving the reliability of this device.

[0056] Example 3 aims to address the problem that the high-temperature gas exiting the first pipe 105 and the second pipe 106 can only reach the upper surface of the solid waste and cannot heat the bottom of the solid waste. This example is an improvement on Example 2. For details, please refer to Example 2. Figures 1 to 10 One end of the third pipe 301 is installed at the bottom of the pyrolysis furnace 103, and multiple fourth pipes 313 are installed on the third pipe 301. The multiple fourth pipes 313 are vertically arranged and evenly distributed along the length of the pyrolysis furnace 103.

[0057] It should be noted that although the stirring rod 109 can agitate the solid waste in the pyrolysis furnace 103, the effect of the stirring rod 109 is limited, which means that the high-temperature gas coming out of the combustion furnace 102 cannot fully contact the waste at the bottom of the pyrolysis furnace 103.

[0058] Please refer to the following: Figure 9 , Figure 10A movable sleeve 305 is slidably installed on the fourth pipe 313, and the movable sleeve 305 slides through the pyrolysis furnace 103. A movable plate 306 is installed at the bottom of the movable sleeve 305. A fixed plate 302 is installed on the fourth pipe 313, and a second tension spring 303 is installed on the fixed plate 302. One end of the second tension spring 303 is fixedly connected to the movable plate 306, and the second tension spring 303 is located outside the pyrolysis furnace 103. A through slot 314 for outputting hot gas is opened on the movable sleeve 305. The top of the moving sleeve 305 is equipped with a push plate 308 for lifting solid waste. A vertical plate 315 is installed on the push plate 308, and an arc plate 316 is installed on the vertical plate 315. A lifting rod 317 is installed on the stirring rod 109. The lifting rod 317 slides in contact with the arc plate 316. When the third pipe 301 is opened, the lifting rod 317 lifts the push plate 308 through the arc plate 316. The high-temperature gas in the fourth pipe 313 enters the pyrolysis furnace 103 through the through groove 314.

[0059] In this embodiment: the fourth pipe 313 is evenly arranged along the length of the pyrolysis furnace 103, thereby heating the bottom of the solid waste in the pyrolysis furnace 103 and causing the solid waste to decompose rapidly. Moreover, a movable sleeve 305 is slidably installed on the fourth pipe 313. When the third pipe 301 is opened, gas enters the pyrolysis furnace 103 through the through groove 314. In addition, a push plate 308 is installed at the top of the movable sleeve 305. When the push plate 308 moves upward, it will push up the solid waste around the through groove 314 to prevent the solid waste from clogging the through groove 314.
