Description

Technical Field

[0001] The invention relates to the technical field of garbage treatment equipment, in particular to a high-temperature cracking device for treating domestic garbage. Background Art

[0002] The high-temperature cracking technology of domestic waste is to decompose the waste into a series of combustible gases, such as methane, hydrogen, carbon monoxide, etc. in a low-temperature decomposition furnace. The combustible gases enter the combustion furnace through pipes and burn in the combustion furnace. The heat released by the gas combustion enters the decomposition furnace through another pipe to provide heat for the decomposition of the waste. In this process, no additional fuel is required, thereby achieving the goal of using waste to manage waste. Compared with direct incineration of waste, dioxin emissions are greatly reduced after the waste is treated with high-temperature cracking.

[0003] In the existing high-temperature cracking equipment for domestic waste treatment, the combustible gas produced by the decomposition of waste in the decomposition furnace has a high carbon content, which can easily cause carbon deposition in the pipeline connecting the decomposition furnace and the combustion furnace, causing pipeline blockage, which is not conducive to the circulation of gas between the decomposition furnace and the combustion furnace, making it impossible for the gas to be fully burned, resulting in a high dioxin content in the emitted gas, which is not environmentally friendly; therefore, it does not meet the existing needs. In this regard, we propose a high-temperature cracking equipment for domestic waste treatment. Summary of the invention

[0004] The present invention provides a high-temperature cracking device for treating domestic waste, which is equipped with a two-way circulation of gas in a pipeline between a decomposition furnace and a combustion furnace. The circulating gas can fully oxidize carbon deposits in the pipeline to prevent pipeline blockage, which is conducive to the circulation of gas between the decomposition furnace and the combustion furnace, thereby making the discharged gas have a lower dioxin content and a more environmentally friendly beneficial effect. The invention solves the problem that the existing high-temperature cracking device for treating domestic waste mentioned in the above background technology, in which the combustible gas generated by the decomposition of garbage in the decomposition furnace has a high carbon content, which easily causes carbon deposits in the pipeline connecting the decomposition furnace and the combustion furnace, causing pipeline blockage, which is not conducive to the circulation of gas between the decomposition furnace and the combustion furnace, so that the gas cannot be fully burned, resulting in a high dioxin content in the discharged gas and not being environmentally friendly.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0030] Example 1: This example aims to promote the solution of the existing high-temperature cracking equipment for domestic waste treatment. The combustible gas produced by the decomposition of garbage in the decomposition furnace has a high carbon content, which easily causes carbon deposition in the pipeline connecting the decomposition furnace and the combustion furnace, causing the pipeline to be blocked, which is not conducive to the circulation of gas between the decomposition furnace and the combustion furnace, so that the gas cannot be fully burned, resulting in a high dioxin content in the discharged gas, which is not environmentally friendly. Please refer to Figures 1 to 10A high-temperature cracking device for treating domestic waste includes a bracket 107, a cracking furnace 103 is installed on the bracket 107, a combustion furnace 102 is arranged above the cracking 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 cracking furnace 103, a motor 101 is also installed on the bracket 107, a rotating shaft 108 is installed on the motor 101, and a plurality of stirring rods 109 for stirring garbage are arranged on the rotating shaft 108. It should be noted that a blower for supplementing oxygen is arranged on the combustion furnace 102, and a pressure relief valve (not shown in the figure) is also arranged on the combustion furnace 102 to prevent the combustion furnace 102 from being over-pressured. The blower and the pressure relief valve are both existing technical means in this field and are not described in detail here.

[0031] Among them, please refer to Figure 1 , Figure 5 The first pipeline 105 is provided with a first valve 201, which is configured as a three-way pipe. The first valve 201 is connected to the first pipeline 105, and the first valve 201 is provided with a first moving block 213 for opening or closing the first pipeline 105.

Both the moving block 218 and the moving block No. 1 213 are provided with a through hole 224, and a one-way valve 225 is arranged in the through hole 224. The one-way valve 225 only allows the gas to enter the combustion furnace 102 from the cracking furnace 103 in one direction. It should be noted that the one-way valve 225 includes a baffle hinged in the through hole 224, and a tension spring is arranged on the side of the baffle. The baffle can only be deflected in one direction, so that the gas can only pass 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 elaborated here.

[0032] 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 opened, 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 cracking furnace 103 through the first pipeline 105, and the combustible gas in the cracking furnace 103 enters the combustion furnace 102 through the second pipeline 106 and the one-way valve 225 on the second moving block 218. Conversely, when the second valve 226 is opened, 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 cracking furnace 103 through the second pipeline 106. At this time, the combustible gas entering the cracking furnace 103 enters the combustion furnace 102 through the first pipeline 105 and the one-way valve 225 on the first moving block 213.

[0033] Among them, please refer to Figure 4 , Figure 5 A moving rod 202 is installed at one end of the moving block 213, and a rack 212 is arranged on the moving rod 202. A fixed block 208 is installed on the cracking 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 in transmission, and a gear 211 is arranged on the rotating rod 209. The gear 211 is intermittently meshed with the rack 212.

[0034] Among them, please refer to Figure 7 , Figure 8 A No. 2 moving rod 219 is installed at one end of the No. 2 moving block 218, and a second rack 221 is arranged on the No. 2 moving rod 219. A second gear 220 is arranged on the rotating rod 209. The second gear 220 is intermittently meshed with the second rack 221. The No. 1 gear 211 and the second gear 220 are set as incomplete gears. When the No. 1 gear 211 is meshed with the No. 1 rack 212, the second gear 220 is not meshed with the second rack 221.

[0035] For details, please refer to Figure 1 A flange 203 is provided on the rotating shaft 108, and a first roller 204 with a groove is detachably mounted on the flange 203 through bolts and nuts. A second roller 206 with a groove is mounted on one end of the rotating rod 209, and a belt 205 is provided on the second roller 206, and one end of the belt 205 is mounted on the first roller 204.

[0036] Also, please refer to, Figure 5 , Figure 6 A No. 1 reset mechanism 2200 for resetting the No. 1 moving rod 202 is provided at one end of the No. 1 moving rod 202. The No. 1 reset mechanism 2200 includes a No. 1 sleeve 210. A No. 1 moving plate 223 is slidably installed in the No. 1 sleeve 210. The No. 1 moving plate 223 is fixedly connected to the No. 1 moving rod 202. A compression spring 217 is provided in the No. 1 sleeve 210. One end of the compression spring 217 is in contact with the No. 1 moving plate 223. A No. 2 reset mechanism 2400 is installed at one end of the No. 2 moving rod 219. The No. 2 reset mechanism 2400 is configured in the same manner as the No. 1 reset mechanism 2200.

[0037] Also, please refer to Figure 5 A No. 2 sleeve 216 is installed on both the No. 1 moving rod 202 and the No. 2 moving rod 219, and a No. 1 pull rod 214 is installed on one end of the No. 1 moving block 213 and the No. 2 moving block 218. The No. 1 pull rod 214 is slidably installed in the No. 2 sleeve 216, and a No. 1 tension spring 215 is arranged in the No. 2 sleeve 216, and one end of the No. 1 tension spring 215 is fixedly connected to the No. 1 pull rod 214.

[0038] It should be noted that the design of the No. 2 sleeve 216 and the No. 1 pull rod 214 helps to extend the opening time of the first valve 201 or the second valve 226. Specifically, when the No. 1 gear 211 is meshed with the No. 1 rack 212, the No. 1 moving rod 202 pulls the No. 1 moving block 213 through the No. 1 tension spring 215, thereby opening the first valve 201 or the second valve 226. At this time, the No. 1 gear 211 is still meshed with the No. 1 rack 212, and the No. 1 moving block 213 stops moving. The No. 1 tension spring 215 is stretched under the action of the No. 1 moving rod 202, thereby extending the opening time of the first valve 201 or the second valve 226.

[0039] In this embodiment, as the motor 101 runs, the motor 101 drives the second roller 206 to rotate through the first roller 204, and further drives the rotating rod 209 to rotate. When the rotating rod 209 rotates, the first gear 211 will intermittently mesh with the first rack 212, and the second gear 220 will intermittently mesh with the second rack 221. When the first gear 211 is meshed with the first rack 212, the second gear 220 is not meshed with the second rack 221. At this time, the first moving rod 2 02 drives the No. 1 moving block 213 to move to the outside of the first valve 201, the first pipeline 105 is opened, the one-way valve 225 on the No. 2 moving block 218 is opened, and the high-temperature gas in the combustion furnace 102 enters the cracking furnace 103 through the first pipeline 105, and the combustible gas in the cracking furnace 103 enters the combustion furnace 102 through the second pipeline 106 and the one-way valve 225 on the No. 2 moving block 218. Similarly, when the No. 1 gear 211 is not meshed with the No. 1 rack 212, and the second gear When the rack 220 is meshed with the second rack 221, the first pipeline 105 is closed, and the one-way valve 225 on the No. 1 moving block 213 is opened, and the high-temperature gas in the combustion furnace 102 enters the cracking furnace 103 through the second pipeline 106. At this time, the combustible gas entering the cracking furnace 103 enters the combustion furnace 102 through the first pipeline 105 and the one-way valve 225 on the No. 1 moving block 213, thereby realizing that the gas in the first pipeline 105 and the second pipeline 106 can intermittently flow in both directions, so that the airflow can circulate in both directions between the combustion furnace 102 and the cracking furnace 103. The high-temperature gas coming out of the combustion furnace 102 can oxidize and remove the carbon deposits generated in the first pipeline 105 and the second pipeline 106, thereby preventing the first pipeline 105 or the second pipeline 106 from being blocked, which is conducive to the full circulation of the gas between the first pipeline 105 and the second pipeline 106, so that the gas generated by the decomposition of garbage is fully decomposed, and the dioxin content of the exhaust gas is reduced, which is more environmentally friendly.

[0040] Embodiment 2: This embodiment is intended to solve the problem that when the first pipeline 105 and the second pipeline 106 are opened alternately, the gas that has just entered the combustion furnace 102 immediately returns to the cracking furnace 103, and the circulating gas cannot be fully burned. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 10 A third pipeline 301 is installed on the combustion furnace 102. The third pipeline 301 is installed in the middle of the combustion furnace 102 along the length direction. The other end of the third pipeline 301 is connected to the cracking furnace 103. When the first pipeline 105 and the second pipeline 106 are closed at the same time, the third pipeline 301 is opened.

[0041] For details, please refer to Figure 3 , Figure 6 A third valve 309 and a fourth valve 310 are installed on the third pipeline 301. The third valve 309 and the fourth valve 310 are arranged in the same manner as the first valve 201. The third valve 309 is arranged on a side of the third pipeline 301 adjacent to the No. 1 reset mechanism 2200. A No. 3 moving block 318 is installed in the third valve 309. A No. 3 moving rod 307 is installed on one side of the No. 3 moving block 318. The No. 3 moving rod 307 passes through the No. 1 sleeve 210, and one end of the No. 3 moving rod 307 is fixedly installed on the No. 1 moving plate 223.

[0042] Also, please refer to Figure 7 , Figure 8 The No. 2 reset mechanism 2400 includes a No. 3 sleeve 207, and the No. 2 reset mechanism 2400 also includes a No. 2 moving plate 222. The No. 3 sleeve 207 is configured the same as the No. 1 sleeve 210, and the No. 2 moving plate 222 is configured the same as the No. 1 moving plate 223. The fourth valve 310 is disposed on a side of the third pipeline 301 adjacent to the No. 2 reset mechanism 2400, and a No. 4 moving block 319 is installed in the fourth valve 310, and a No. 4 moving rod 304 is installed on one side of the No. 4 moving block 319, and the No. 4 moving rod 304 passes through the No. 3 sleeve 207, and one end of the No. 4 moving rod 304 is fixedly installed on the No. 2 moving plate 222.

[0043] In this embodiment: the third pipeline 301 is installed on the combustion furnace 102. When the first valve 201 and the second valve 226 are closed at the same time, the No. 1 moving rod 202 drives the No. 3 moving rod 307 to move to one side through the No. 1 moving plate 223, and the No. 2 moving rod 219 drives the No. 4 moving rod 304 to move to one side through the No. 2 moving plate 222, so that the third valve 309 and the fourth valve 310 are opened at the same time, and the gas in the combustion furnace 102 enters the cracking furnace 103 through the third pipeline 301, and the third pipeline 301 is arranged in the middle position of the combustion furnace 102. In the time period when the third valve 309 and the fourth valve 310 are closed at the same time, the third pipeline 301 provides a heat source for the gas entering the cracking furnace 103 for auxiliary heating. In addition, the gas fully burned in the combustion furnace 102 enters the cracking furnace 103, preventing the first pipeline 105 and the second pipeline 106 from entering the cracking furnace 103 without being fully burned during the gap between the alternate openings, thereby improving the reliability of the device.

[0044] Embodiment 3: This embodiment is intended to promote the solution of the problem that the high temperature gas from the first pipe 105 and the second pipe 106 can only contact the upper surface of the solid waste and cannot heat the bottom of the solid waste. This embodiment is an improvement made on the basis of embodiment 2.
