Abstract

The invention relates to a medical incineration fly ash treatment device. The medical incineration fly ash treatment device comprises a high-pressure reaction kettle, an upper filtering chamber and a lower filtering chamber. By arranging all the components, medical incineration fly ash treated through a supercritical water oxidation technology can be efficiently separated from water, the treating water can be converted into circulating water through further reaction and high-efficiency filtering, and accordingly, high harmless treatment of medical waste is achieved.

Description

technical field [0001] The invention belongs to the field of processing equipment for medical equipment, and in particular relates to a medical waste processing device, in particular to a medical incineration fly ash processing device. Background technique [0002] The most conventional treatment method for medical waste is to incinerate after classification, but the fly ash after incineration contains a lot of heavy metals. If the incineration fly ash is directly disposed of in landfill, it will greatly increase the concentration of heavy metals in the land. Therefore, the heavy metal removal treatment of incineration fly ash is the research focus of existing medical waste treatment. Supercritical water oxidation technology means that when the temperature reaches 374.2°C and the pressure reaches 22.1MPa, water will form supercritical water, and when solid matter is in contact with supercritical water, supercritical water will dissolve organic matter, oxygen and heavy metal ...
