[0052] The present invention application also provides a hazardous waste heat treatment process, using any of the above hazardous waste heat treatment equipment, comprising the following steps:

[0053] S1. Before crushing the solid waste, the solid matter is placed into the reactor 1 through the discharge box 4 and then the discharge box 4 is closed. Large solid waste is accumulated on the discharge net 15 to facilitate subsequent cutting processing.

[0054] S2. During cutting, the second cutting blade 39 and the first cutting blade 14 are reversed and matched to each other to crush the solid in the reactor 1, and the combustion and heating box 10 burns and heats the objects placed in the reactor 1;

[0055] Specifically, during cutting, the motor 6 is started, and the output end of the motor 6 drives the linkage shaft 13 to rotate, the linkage shaft 13 rotates to drive the first gear 28 and multiple first cutting knives 14 to rotate, the first gear 28 rotates to drive the second gear 29 to rotate, the second gear 29 rotates to drive the fourth gear 30 to rotate, the fourth gear 30 rotates to drive the third gear 32 to rotate, the third gear 32 rotates to drive the sleeve 11 to rotate, the sleeve 11 rotates to drive multiple second cutting knives 39 to rotate, the second cutting knives 39 and the first cutting knives 14 rotate in reverse to crush the solid in the reactor 1.

[0056] S3, the fully burned powder after cutting falls through the discharge net 15 and can be discharged by opening the sealing plate 3;

[0057] Specifically, in order to achieve better crushing, the linkage shaft 13 rotates to drive the driving column 36, and the driving column 36 rotates to drive the V-shaped annular groove 37 to rotate. At this time, the convex shaft 35 moves in the V-shaped annular groove 37, driving the feeding net 15 to move up and down, so that the second cutting knife 39 and the first cutting knife 14 can be better cut. After cutting, the fully burned powder falls through the feeding net 15 and can be discharged by opening the sealing plate 3.

[0058] S4. A large amount of smoke is generated during combustion and is discharged through the exhaust pipe 7. The water absorption filter plate 27 filters the smoke contained in the air and squeezes out the sewage attached to the surface of the water absorption filter plate 27 by the absorption gas.

[0059] Specifically, a large amount of smoke is generated during combustion and discharged through the exhaust pipe 7. The water absorption filter plate 27 filters the smoke contained in the air. The sleeve 11 drives the cam 31 to rotate when rotating. The cam 31 rotates through the guide groove 38 to change the position of the driving shaft 33, and then reciprocates to push and pull to change the position of the Z-shaped plate 17. When the Z-shaped plate 17 moves, it drives the blocking plate 19 and the L-shaped plate 18 to move. When the blocking plate 19 reciprocates, the water source above the water-blocking plate 9 is discharged through the through hole 20. When it is not moving, the oblique water hole 21 is blocked.

[0060] In the present application, the second cutting knife 39 and the first cutting knife 14 are reversely matched to each other to crush the solid in the reactor 1, and the feeding net 15 moves up and down to better enable the second cutting knife 39 and the first cutting knife 14 to cut. After cutting, the fully burned powder falls through the feeding net 15 and can be discharged by opening the sealing plate 3. A large amount of smoke will be generated during combustion, which will be discharged through the exhaust pipe 7. The water absorption filter plate 27 filters the smoke contained in the air; at the same time, the L-shaped plate 18 drives the L-shaped plate 18 to move through the Z-shaped plate 17, and the connecting shaft 22 drives the slide 23, the sleeve plate 25, and the extrusion shaft 26 to move together. The extrusion shaft 26 presses the surface of the water absorption filter plate 27 and moves along the surface of the arc surface 42. The stretching spring 24 becomes longer, and the sewage attached to the surface of the water absorption filter plate 27 by the absorption gas is squeezed out for subsequent long-term cleaning. In this way, larger solid hazardous wastes can be fully burned and the harmful gases generated during combustion can be filtered.
