Embodiment 1

[0033] The structure of the inner wall of the rotary kiln for hazardous waste incineration is basically as attached figure 1 As shown, it includes multiple sets of material dispersion structures arranged in sequence from left to right, combined with figure 2 As shown, the material dispersion structure includes a plurality of refractory bumps 1 arranged circumferentially along the inner wall of the cylinder 3 of the rotary kiln. The number of refractory bumps 1 is set according to actual needs. In this embodiment, there are 22 refractory bumps 1 ; The refractory bumps 1 of the material dispersion structure are connected end to end, and the refractory bumps 1 use refractory bricks.

[0034] The refractory bumps 1 of the material dispersing structure are all arranged in a dislocation in height, and each group of material dispersing structures are arranged in a dislocation in height. In this embodiment, the dislocation arrangement of the refractory bump 1 of the material dispers...

Embodiment 2

[0041] The difference between embodiment 2 and embodiment 1 is that in this embodiment, the dislocation arrangement of the refractory bumps 1 of the material dispersion structure is that the material dispersion structure includes multiple sets of refractory bump groups, and the refractory bump groups include A high refractory bump and a low refractory bump, the thickness difference between two adjacent refractory bumps 1 is 100mm, and the thickness of the two adjacent refractory bumps 1 with a larger thickness is the same, that is, the dispersed structure of each group of materials The thickness of the refractory bump 1 is set according to the cycle of a, a+100mm, a...a, a+100mm.

[0042]The dislocation method of the material dispersion structure is that the thickness difference between two adjacent groups of material dispersion structures is 100 mm, that is, the thickness difference between two adjacent refractory bumps 1 of the adjacent two groups of material dispersion struc...

Embodiment 3

[0045] Embodiment 3 differs from Embodiment 1 only in that, as image 3 As shown, in this embodiment, each group of material dispersion structure is provided with 32 pieces of refractory bumps 1, and the dislocation arrangement of the refractory bumps 1 of the material dispersion structure is that the 4 pieces of refractory bumps adjacent to each group of material dispersion structure The block 1 is marked as A, and the refractory bump 1 adjacent to A is marked as B, and the thickness of B is 50mm larger than that of A, that is, the refractory bump 1 of each group of material dispersion structure is in accordance with A, B, A. ..... Cycle settings for A and B.

[0046] The dislocation setting method of the material dispersion structure is as follows: Figure 4 As shown, the adjacent four groups of material dispersion structures are marked as X, and the group of material dispersion structures adjacent to X is marked as Y. The thickness of Y is 50mm larger than the thickness of...

Abstract

The invention belongs to the technical field of structures for driving incineration materials to rotate and mix, and discloses an inner wall structure of a hazardous waste incineration rotary kiln. The inner wall structure comprises a plurality of sets of material dispersing structures sequentially arranged in the length direction of the cylinder body of the rotary kiln, and each material dispersing structure comprises fireproof protruding blocks sequentially arranged in the circumferential direction of the inner wall of the cylinder body of the rotary kiln; and the fireproof protruding blocksof each set of material dispersing structure are staggered in the height direction, and the material dispersing structures are also staggered in the height direction. The inner wall structure solvesthe problems that when the cylinder body of an existing rotary kiln rotates, hazardous waste can be accumulated at the same position, the stirring effect is poor, the hazardous waste is heated unevenly, and the incineration effect is affected.

Description

technical field [0001] The invention belongs to the technical field of structures that drive incineration materials to rotate and mix, and in particular relates to an inner wall structure of 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. At present, rotary kilns are usually used to incinerate hazardous waste, and then the ash after incineration is discharged. During the operation of the rotary kiln, it needs to be continuously rotated and kept at a high temperature, so that the objec...
