Embodiment 1

[0042] Rotary kiln for hazardous waste incineration, basically as attached figure 1 As shown, it includes a support frame and a cylinder body 1 that is rotatably connected to the support frame. The cylinder body 1 is inclined downward from left to right, and the inclination angle of the cylinder body 1 is set according to actual needs. In this embodiment, the cylinder body 1 The angle of inclination is 10°. A motor is also fixed on the support frame, a driving gear is coaxially fixed on the drive shaft of the motor, and a driven ring gear meshed with the driving gear is fixed coaxially outside the cylinder body 1, so that the motor can drive the driving gear to rotate, and through The transmission of the movable ring gear realizes the rotation of the cylinder body 1 .

[0043]The left end of the cylinder body 1 is rotatably connected with a kiln head cover 11, and the right end of the cylinder body 1 is rotatably connected with a kiln tail cover 12. There is a ring of static ...

Embodiment 2

[0054] The difference between embodiment 2 and embodiment 1 is that each material dispersion structure in this embodiment includes 11 groups of refractory bricks, and each group of refractory bricks includes a higher refractory brick 2 and a lower refractory brick. Brick 2, the height difference between the higher refractory brick 2 and the lower refractory brick 2 is 100mm, and all adjacent to the higher refractory brick 2 are lower refractory bricks 2; that is, each material dispersion structure The refractory bricks 2 are arranged in cycles according to the manner of a, a+100mm, a...a, a+100mm.

[0055] In this embodiment, each group of material dispersion structures includes a higher material dispersion structure and a lower material dispersion structure, and the height difference between the higher material dispersion structure and the lower material dispersion structure is 100mm; The adjacent material dispersion structures are all lower material dispersion structures. T...

Embodiment 3

[0058] Embodiment 3 differs from Embodiment 1 only in that, as Figure 4 As shown, in this embodiment, each material dispersion structure includes 8 groups of refractory bricks, and each group of refractory bricks includes a higher refractory brick 2 and three lower refractory bricks 2, and the higher refractory brick 2 and The height difference of the lower refractory bricks 2 is 50mm, and all the adjacent refractory bricks 2 are lower refractory bricks 2; , a+50mm, a.....a+50mm, a, a, a, a+50mm cycle setting.

[0059] to combine image 3 As shown, each group of material dispersion structures in this embodiment includes a higher material dispersion structure and three lower material dispersion structures, and the height difference between the higher material dispersion structure and the lower material dispersion structure is 50 mm. And adjacent to the higher material dispersion structure are lower material dispersion structures. Mark a lower material dispersion structure a...

Abstract

The invention belongs to the technical field of equipment for incinerating waste in a rotary barrel body or a vibration barrel, and discloses a rotary kiln for hazardous waste incineration. The rotarykiln comprises a support frame and a barrel body rotationally connected to the support frame, a motor for driving the barrel body to rotate is also fixed on the support frame, and a kiln head cover and a kiln tail cover are respectively arranged at the two ends of the barrel body; the barrel body is rotatably and hermetically connected with the kiln head cover and the kiln tail cover, an incineration pipe for incinerating the hazardous waste is arranged on the kiln tail cover, a slag outlet is formed in the lower part of the kiln tail cover, multiple groups of material dispersion structures are arranged on the inner wall of the barrel body in the length direction, and each group of material dispersion structure comprises multiple groups of refractory brick groups arranged in the circumferential direction of the inner wall of the barrel body; and the plurality of groups of material dispersion structures are convex-tooth-shaped. The rotary kiln solves the problems that the inner wall ofa barrel body of an existing rotary kiln is smooth and round, the hazardous waste can be accumulated at the same position during operation, stirring and mixing cannot be achieved, then the hazardouswaste is heated unevenly, and the hazardous waste incineration efficiency is affected.

Description

technical field [0001] The invention belongs to the technical field of equipment for incinerating waste in a rotary cylinder or a vibrating cylinder, and in particular relates to a rotary kiln for hazardous waste incineration. Background technique [0002] Hazardous waste is the abbreviation of hazardous waste, which refers to waste that is included in the national hazardous waste list or identified according to the national hazardous waste identification standards and identification methods with hazardous waste characteristics. Most hazardous wastes contain toxic and harmful substances, which will pollute the environment if they are discharged randomly, so they usually need to be treated before they are discharged. [0003] The current treatment method for hazardous waste is to put it into the rotary kiln, perform high-temperature incineration treatment in the rotary kiln, and then discharge the ash after incineration. During the operation of the rotary kiln, it needs to b...
