Description

Technical Field

[0002] Garbage pyrolysis technology is a process in which municipal solid waste is heated under oxygen-free or anoxic conditions to cause thermal cracking of the organic matter in the waste, converting it into gas, liquid, and solid residues.

Pyrolysis technology can effectively reduce the emission of harmful substances such as dioxins produced during the incineration process and is a more environmentally friendly treatment method. Tar is a mixture of oil and dust produced during the waste incineration process. It has no fluidity at medium and low temperatures and has strong adhesion. If it is not treated at high temperature, it needs to be shut down and cleaned regularly, which is relatively labor-intensive. In addition, some existing pyrolysis furnaces do not have the structure to process tar at high temperature and require a separate heat source for treatment, which is energy-consuming and inconvenient to use.

[0031] Specifically, a cleaning rod 121 is slidably connected to the inside of the treatment tube 12, and part of the heat generated by the garbage combustion is guided to the treatment tube 12 through the heat conduction plate 131, so that the smoke can be automatically pyrolyzed after passing through the treatment tube 12, without the need for an external heat source, saving energy. After the smoke is treated, it climbs through the spiral tube 101 and is then discharged. The heat can be used to enhance the insulation effect of the pyrolysis cylinder 10, realizing full utilization of the heat of garbage combustion.

[0032] Example 1

[0033] like Figure 2-3 As shown, in this embodiment, a base 13 is provided below the pyrolysis cylinder 10, and the top of the base 13 is fixedly connected to a limiting shell 134, and two hydraulic rods 135 are fixedly embedded in the top of the limiting shell 134. The top of the heat conducting plate 131 is fixedly connected to a plurality of heat conducting rods 1371, and the top ends of the plurality of heat conducting rods 1371 are fixedly connected to a supporting plate 137, and the bottom of the heat conducting plate 131 is fixedly connected to a fixing plate 136.

[0034] In this embodiment, the pyrolysis cylinder 10 and other components are supported by the base 13, and the hydraulic rod 135 is started to move the supporting plate 137 and the heat conducting plate 131 and other components out of the pyrolysis cylinder 10, so that the waste incineration residue is poured out. The heat generated by the burning of the waste is conducted through the supporting plate 137, the heat conducting rod 1371 and the heat conducting plate 131, and is guided to the inside of the treatment tube 12 through the rectangular plate 132 and the heat conducting pipe 133, so that the inside of the treatment tube 12 is locally overheated, and the smoke will be pyrolyzed when it moves down along the treatment tube 12, without the need for external The tar in the flue gas is treated by connecting to a heat source to prevent the tar from condensing, and the tar is decomposed into harmless gas which enters the interior of the spiral tube 101 and is discharged to the outside through the spiral tube 101 and the exhaust pipe 103. During the process, the heat of the gas can be conducted to the interior of the pyrolysis cylinder 10 through the exhaust pipe 103 for insulation, thereby realizing heat recycling. The heat conducting plate 131 absorbs the heat of the garbage combustion and guides it to the heat conducting pipe 133 through the rectangular plate 132. The heat conducting pipe 133 heats the treatment tube 12, so that the flue gas passes through the interior of the treatment tube 12 for pyrolysis.

[0035] like Figure 2 As shown, in this embodiment, a heat-insulating sleeve 102 is fixedly sleeved on the outer wall of the pyrolysis cylinder 10, and two regulating plates 104 are symmetrically rotatably connected to the top of the pyrolysis cylinder 10 through hinges.

[0036] In specific implementation, the insulation sleeve 102 uses polyurethane foam, which is a highly efficient insulation material with extremely high thermal resistance, light weight, and good adhesion. It can enhance the insulation performance of the pyrolysis cylinder 10, reduce heat loss, and enhance the utilization of heat from garbage combustion, making garbage incineration more thorough. By opening the control panel 104, garbage that needs to be incinerated can be added to the inside of the pyrolysis cylinder 10.

[0037] Example 2

[0038] On the basis of the first embodiment, in order to be able to automatically clean the multiple processing tubes 12, it is to prevent the processing tubes 12 from being blocked and affecting subsequent use.

[0039] like Figure 1 As shown, in this embodiment, a plurality of filter plates 114 are fixedly connected to the inner top wall of the diversion cylinder 11, two partitions 113 are slidably connected to the inside of the diversion cylinder 11, two hydraulic rods 112 are fixedly connected to the outer wall of the diversion cylinder 11, and the output end of the hydraulic rod 112 is fixedly connected to the adjacent partition 113. The top of the pyrolysis cylinder 10 is fixedly connected to the connecting cylinder 115, and the top of the connecting cylinder 115 passes through the diversion cylinder 11 and is fixedly connected thereto.

Multiple hydraulic rods 144 are provided, and hydraulic rods 144 are fixedly connected to adjacent insulation seats 105. A baffle 145 is fixedly connected between the output ends of two adjacent hydraulic rods 144.

[0040] In specific implementation, the filter plate 114 uses an activated carbon mesh plate to initially filter the smoke and dust. The hydraulic rod 112 is started to regulate the partition 113. After the partition 113 is opened, the smoke enters the inside of the diversion cylinder 11 through the connecting cylinder 115, and enters the inside of the designated rectangular cylinder 111 through the diversion cylinder 11. The two rectangular cylinders 111 are used alternately. When one rectangular cylinder 111 is used, the processing pipe 12 inside the other rectangular cylinder 111 can be cleaned. By setting the two partitions 113, the two The rectangular cylinders 111 can be used alternately, because even after filtering and pyrolysis, some tar will adhere to the inner wall of the treatment tube 12. After the garbage is incinerated, the two hydraulic rods 144 can be started to drive the baffle 145 away from the bottom of the treatment tube 12, and the two hydraulic rods 143 can be started to make multiple cleaning rods 121 move downward synchronously. The bottom end of the cleaning rod 121 is used to scrape the inside of the treatment tube 12, and the residual tar and impurities on the inner wall of the treatment tube 12 are pushed out from the bottom end of the treatment tube 12 for cleaning.
