As shown in fig. 1 to 13, the present invention provides a two-stage waste drying and incineration disposal system, comprising an incineration apparatus 10 and a residue disposal apparatus 20.
The incineration device 10 comprises a first bracket 11, a hollow blade shaft 12, a cylinder 13, a hollow blade 14, a kiln hood 15, a kiln tail hood 16, a rotary joint 17 and a first motor 18. The hollow blade shaft 12 is obliquely disposed on the first bracket 11, and the hollow blade shaft 12 has a first cavity 121 extending in the axial direction inside and a second cavity 122 located at the periphery of the first cavity 121. The cylinder 13 is fitted over the outside of the hollow blade shaft 12 in the extending direction of the hollow blade shaft 12. The cylinder 13 comprises a drying section 131 and an incineration section 132, the incineration section 132 being located below the drying section 131.
A plurality of hollow paddles 14 are spaced apart on the hollow paddle shaft 12 at the drying section 131. The hollow blades 14 communicate with the second cavities 122 inside the corresponding hollow blade shafts 12 through the first conduit 100, and also communicate with the first cavities 121 inside the corresponding hollow blade shafts 12 through the second conduit 110. The pressurized heat medium enters the second cavity 122 in the hollow blade shaft 12 from the heat medium rotary joint 17 at one end, gradually flows to the hollow blade 14 through the first pipeline 100, then flows back to the first cavity 121 through the second pipeline 110, and finally is discharged from the rotary joint 16. This achieves internal heating of the waste from the inside.
The kiln head cover 15 is sleeved at one end of the cylinder 13 close to the drying section 131, and the kiln head cover 15 is provided with a feed inlet 151 communicated with the inside of the cylinder 13. An igniter 163 is arranged in the kiln tail hood 16, the kiln tail hood 16 is sleeved at one end of the cylinder 13 close to the incineration section 132, and a discharge hole 161 communicated with the inside of the cylinder 13 is formed in the kiln tail hood 16. The rotary joint 17 is provided at one end of the hollow blade shaft 12 and is rotatably connected to the first bracket 11 through a bearing housing. The first motor 18 is arranged on the first bracket 11, and drives the hollow blade shaft 12 to rotate through the transmission of the gear set.
The residue processing apparatus 20 includes a screw feeder 21 and a second motor 22. The screw feeder 21 is arranged obliquely, the lower end of the screw feeder 21 is positioned below the kiln tail hood 16 and is communicated with a discharge hole 161 on the kiln tail hood 16, the lower end of the screw feeder 21 is provided with a water storage tank 211, and the upper end of the screw feeder is provided with a slag hole 212. The second motor 22 is used for controlling the rotation of a feed shaft 213 in the screw feeder 21, and the feed shaft 213 is provided with screw blades 214 in the extending direction.
The residue falling from the discharge port 161 of the kiln tail hood 16 enters the lower end of the screw feeder 21 from the discharge port 161 and is mixed with water in the water storage tank 211. The design of the water storage tank 211 prevents the residue from generating dust when falling out, thereby improving the working environment. After the residue is mixed with water, the residue moves upward by the rotation of the feed shaft 213 and the screw blade 214, and the water adhered to the residue flows back to the water storage tank 211 from the gap between the screw blade 214 and the housing, and when the residue moves to the upper end of the screw feeder 21, the residue falls out from the slag hole 212.
The waste heat recovery device sends waste heat of residues in the spiral feeder 21 into the cylinder 13 through the kiln tail cover 16, and drying and burning of waste in the cylinder 13 are promoted. The dried waste enters the incineration section 132, is incinerated under the ignition action of the igniter 163 in the kiln tail hood 16, and the residue after the incineration of the waste falls out from the discharge port 161 under the action of gravity.
In one embodiment, the interior of the cylinder 13 has a first jacket 133 for containing a thermal medium. The kiln head cover 15 and the kiln tail cover 16 are in sealing connection with the cylinder 13.

The heat medium inlet 162 and the heat medium outlet 152 are both in communication with the first jacket 133 through the cavity.
The pressurized heat medium enters the first jacket 133 of the cylinder 13 from the heat medium inlet 162 of the kiln tail hood 16 and moves towards the kiln head hood 15 through a pressurizing device, preferably a pressure pump. The heat medium entering the first jacket 133 first passes through the incineration section 132, and the incineration of the waste in the incineration section 132 further adds heat to the heat medium in the first jacket 133. The heat medium then enters the drying section 131 to exchange heat with the waste in the drying section 131, thereby drying the waste in the drying section 131 by means of external heating. The external heating mode of the first jacket 133 is combined with the internal heating mode of the hollow blade shaft 12 and the hollow blade 14, so that the drying effect of the waste is better, and the subsequent incineration of the waste is facilitated.
In one embodiment, a guide cylinder 40 is arranged in the cavity, preferably the guide cylinder 40 is of an H-shaped structure, and two sides of the guide cylinder 40 are in sealing connection with the kiln head cover 15 or the kiln tail cover 16 through sealing rings 90. The guide shell 40 is fixedly connected with the kiln head cover 15 or the kiln tail cover 16. The guide cylinder 40 divides the cavity into a third cavity 31 and a fourth cavity 32 located inside the third cavity 31. The guide cylinder 40 is uniformly provided with a plurality of first through holes 41 which are used for communicating the third cavity 31 with the fourth cavity 32 along the circumferential direction, and the cylinder 13 is provided with a plurality of second through holes 134 which are used for communicating the fourth cavity 32 with the first jacket 133.
The heat medium enters the cavity at the kiln tail hood 16 from the heat medium inlet 162, diffuses into the whole third cavity 31, further diffuses into the fourth cavity 32 through the first through holes 41 on the guide cylinder 40, passes through the second through holes 134 on the first jacket 133 at the kiln tail hood 16, and finally enters the first jacket 133, so that heat exchange is carried out with the materials in the cylinder 13. The heat medium having completed the heat exchange passes through the opposite path and finally flows out of the heat medium outlet 152 on the kiln head cover 15. The guide cylinder 40 guides the flow of the heat medium, and the heat medium is uniformly diffused to the third cavity 31 and the fourth cavity 32 after being guided by the guide cylinder 40, so that the speed of the heat medium entering and exiting the first jacket 133 is more stable, and the drying of the waste is more uniform.
