Description

[0002] The existing medical waste is first poured into the incinerator by the feeding elevator during the treatment, and the waste in the furnace is dried and then pyrolyzed at a temperature of 600-750 DEG C. The main pyrolysis products include residual carbon (fixed carbon), hydrogen, methane, carbon monoxide, CO2, liquid tar, oil compounds (acetic acid, acetone, and complex hydrocarbons), etc. The residual carbon and other residues are burned in the combustion zone at the lower part of the furnace body, and the coking residues after burning are crushed into 100mm or less by the mechanical extrusion of the furnace grate and discharged into the water seal tank at the bottom of the furnace, and then discharged through the wet slagging system. The mixed flue gas generated by the pyrolysis gasifier enters the secondary combustion chamber, and is fully burned by adding oxygen through the secondary air. The temperature in the furnace is controlled at 1100 DEG C. After the high-temperature flue gas is cooled by the flue-type waste heat boiler and the quencher, the temperature is reduced to 200 DEG C. The flue gas enters the tail gas treatment system, and the quencher can make the flue gas temperature drop from 510 DEG C to 200 DEG C in less than 1 second. The flue gas is treated by the tail gas treatment system and discharged into the atmosphere after reaching the standard.

[0030] The positioning scraping piece 75 comprises fixed rotating plates 751, positioning side plates 752, positioning shafts 753 and scraping plates 754, the fixed rotating plates 751 are provided with two, the two fixed rotating plates 751 are fixedly connected at the two ends of the fixed shaft 74 respectively, the bottom of the fixed rotating plate 751 is provided with a limiting convex strip, the positioning side plate 752 is provided with a guide groove corresponding to the position of the limiting convex strip, the positioning side plate 752 is provided with two, and the scraping plate 754 is fixedly installed at the bottom of the two positioning side plates 752.

[0031] Specific implementation process: the medical waste enters the bottommost fixed step 3 through the inlet 11 and the material inclined plate 2, and due to the arrangement of the material guide inclined surface 5 of the fixed step 3, the medical waste enters the bottom movable step 4 during the combustion process. During the combustion process, the movable step 4 is driven by the reciprocating lifting mechanism 6 to move downward relative to the two fixed steps 3 on both sides, and the air outlet 313 on the two fixed steps 3 supplies oxygen to the medical waste during the combustion process, thereby ensuring that the medical waste is fully combusted.

[0032] Subsequently, the movable step 4 moves upward relative to the two fixed steps 3, and the movable step 4 moves upward at the same time, thereby synchronously driving the two support side plates 71 to move upward, and when the support side plates 71 move upward, the guide plate 722 is synchronously driven to move vertically upward. In the initial state, the plurality of dispersion rods 733 are not in contact with the material guide inclined surface 5 on the movable step 4, which can ensure that the medical waste can completely enter the movable step 4. With the continuous upward movement of the movable step 4, the material guide inclined surface 5 of the movable step 4 is in contact with the plurality of dispersion rods 733, and with the upward movement of the movable step 4, the guide plate 722 is moved upward, the guide plate 722 guides and limits the plurality of contact rods 734 through the guide inclined mouth 7221, and the dispersion rods 733 are driven to move relative to the material guide inclined surface 5 of the fixed step 3 through the support sleeve 732, thereby realizing the dispersion of the medical waste combusted on the material guide inclined surface 5, so that the medical waste is fully combusted.

[0033] Until the movable step 4 moves to the side of the fixed step 3 on the other side, and the two material guide inclined surfaces 5 are on the same straight line, the combusted medical waste enters the next fixed step 3.

[0034] At the same time, as the movable step 4 continues to move up to the point where the scraping plate 754 is in contact with the material guiding slope 5 of the movable step 4, the limiting shaft 82 moves up to the inclined position of the limiting groove 13. At this time, the limiting shaft 82 is pulled by the limiting plate 81 to rotate the guide plate 722 relative to the supporting shaft 721. When the guide plate 722 rotates, the supporting sleeve 732 and the dispersing rod 733 are rotated relative to the material guiding slope 5 through the contact rod 734 and the contact plate. At the same time, the dispersing rod 733 pushes the remaining residue on the material guiding slope 5.

[0035] At the same time, when the dispersing rod 733 and the supporting sleeve 732 rotate, the fixed shaft 74 is synchronously rotated by the supporting block 731 and the clamping block 735, and the two fixed rotating plates 751 at both ends of the fixed shaft 74 rotate the positioning side plate 752. Since the positioning side plate 752 is limited by the positioning shaft 753 and the positioning groove 14, the scraping plate 754 moves relative to the material guiding slope 5 of the upward movable step 4 to scrape and prevent residue accumulation on the material guiding slope 5, facilitating the guiding and conveying of burning medical waste until the remaining residue after burning is guided by the top fixed step 3 to the discharging mechanism 12.

[0036] Embodiment Two Please refer to Figures 3 to 5 Embodiment Two is a further supplement to Embodiment One, specifically: the incinerator body 1 is provided with a reciprocating lifting mechanism 6 for synchronously reciprocating lifting the plurality of movable steps 4. The reciprocating lifting mechanism 6 includes a servo motor 61, a rotating rod 62, rotating gears 63, a guide rack 64, and a reciprocating frame 65. The rotating rod 62 penetrates through one side of the incinerator body 1 and is rotatably connected to the incinerator body 1. The servo motor 61 is installed outside the incinerator body 1 and is used to drive the rotating rod 62. The rotating gears 63 are provided in multiple numbers and are equally distributed on the rotating rod 62.

The guide rack 64 is fixedly installed on the reciprocating frame 65, and the reciprocating frame 65 is fixedly installed at the bottom of the movable step 4.

[0037] When reciprocating pushing is performed on the movable step 4, the movable step 4 moves up and down relative to the two fixed steps 3, then the servo motor 61 operates, the rotating rod 62 rotates, when the rotating rod 62 rotates, the plurality of rotating gears 63 on the rotating rod 62 synchronously rotate, when the rotating gears 63 rotate, the guide rack 64 moves relative, further the reciprocating frame 65 drives the movable step 4 to move up and down relative to the fixed step 3.
