Description

Technical Field

[0001] This utility model relates to the field of medical waste treatment technology, specifically to a device for treating medical waste using pyrolysis. Background Technology

[0002] Medical waste (such as infectious waste, pathological waste, and sharps waste) carries pathogens, toxins, and other harmful substances, and improper handling can easily cause environmental pollution and public health risks. Pyrolysis technology, as a treatment method that combines "volume reduction, harmlessness, and resource recovery," transforms medical waste into usable energy (such as pyrolysis gas and fuel oil) or harmless residue through thermochemical reactions in a high-temperature, anaerobic / oxygen-deficient environment. Traditional pyrolysis equipment requires manual delivery of medical waste into the processing tank. If waste accumulates during this process, incomplete material processing can easily occur, making it inconvenient to use. Utility Model Content
