Problems solved by technology
[0002] Medical waste is a high-risk waste. Currently, the main treatment method is incineration. Incineration of medical waste not only requires high investment (2 million yuan per ton of medical waste incineration), but also the waste gas generated during the incineration process will cause pollution to the atmosphere. Pollution (dioxins and PM2.5), there is currently no more effective way to dispose of medical waste

Embodiment Construction
[0008] As shown in the figure: the present invention comprises feed inlet (9), kettle body (10), crankshaft (2), band shift fork connecting rod (11), driving wheel (4), chain (12), driven wheel (5 ), screw conveyor (6), air outlet (13), moving knife (14), static knife (8)
[0009] The working process of this embodiment is as follows:
[0010] Put the medical waste into the kettle from the charging port (1) with a grab machine, break the bag with the moving knife (14) and the static knife (8), and wait until the waste in the kettle is filled to 1 / 2 of the volume of the kettle body , close the charging port, heat the bottom of the kettle body, start the crankshaft (2) and the screw conveyor (6), and before the temperature in the kettle rises to 150°C, all the generated gas will return to the combustion chamber at the bottom for combustion (the main component is water vapor) to wait The kettle temperature continues to heat up, and the gas produced enters the cooler (15) for cool...

The invention discloses a high-temperature thermal cracking device for medical waste. The high-temperature thermal cracking device comprises a kettle and a spiral conveyor. The spiral conveyor is positioned in the inner middle lower portion of the kettle and is driven by a motor, crankshafts driven by motors are arranged in the middle upper portion of the kettle and can drive connecting rod structures with shifting forks, and connecting rods with the shifting forks drive the lower spiral conveyor to reciprocate along the bottom of the kettle. When the high-temperature thermal cracking device is used, the medical waste is loaded into the kettle from a loading opening, the bottom of the kettle is heated, and the crankshafts in the kettle drive the spiral conveyor of the kettle via the connecting rods with the shifting forks, so that the spiral conveyor reciprocates along the bottom of the kettle while the spiral conveyor automatically continuously rotates, generated gas is exhausted from an outlet and completely returns to a heating furnace to be combusted, generated liquid is used as a heat source for the heating furnace, and ash is discharged from ash discharge outlets. The high-temperature thermal cracking device has the advantages that integral disposal procedures are carried out in the airtight kettle under the condition that air is fundamentally isolated, accordingly, environmental pollution can be prevented, the problem of environmental pollution due to dioxin generated when medical waste is incinerated can be completely solved, and carbon emission can be reduced.
Description
1. Technical field [0001] The invention belongs to the technical field of hazardous waste treatment, and in particular relates to a high-temperature pyrolysis device for medical waste. 2. Technical Background [0002] Medical waste is a high-risk waste. Currently, the main treatment method is incineration. Incineration of medical waste not only requires a high investment (2 million yuan per ton of medical waste incineration), but also the waste gas generated during the incineration process will cause pollution to the atmosphere. Pollution (dioxin and PM2.5), there is currently no more effective way to deal with medical waste. 3. Contents of the invention [0003] The purpose of the present invention is to provide a medical waste pyrolysis device with simple structure and reasonable design, which can not only effectively process medical waste, but also avoid pollution to the environment. [0004] In order to achieve the above object, the technical solution adopted by the p...
