Research on the Application of Low-Temperature Pyrolysis Technology for Medical Waste
[Purposes]In recent years,the amount of medical waste generated in China has been continu-ously increasing,and there is an urgent need to improve the problems of traditional technologies through the application of new technologies,enhance the comprehensive disposal capacity of medical waste,and enhance energy utilization efficiency.[Methods]The use of low-temperature pyrolysis technology can convert hydrocarbons in plastic-containing solid waste into high-value by-products.This experiment employs various analytical and detection methods to demonstrate the feasibility of pyrolysis of medical waste disinfection tailings,explore the optimal pyrolysis conditions,and analyze the basic characteristics of pyrolysis products.[Findings]Medical waste disinfection tailings have high calorific value,low mois-ture content,and high volatile content.In a nitrogen atmosphere,after 90 min at 500℃in a pyrolysis sys-tem,a high proportion of combustible gas,pyrolysis oil,pyrolysis carbon residue,and pyrolysis water can be obtained.[Conclusions]The application of low-temperature pyrolysis technology in the field of medi-cal waste treatment and disposal changes various problems existing in traditional disposal technologies,achieves resource utilization,harmless treatment,and reduction in the medical waste treatment process,conforms to the"dual carbon"development plan,and is conducive to building a green,low-carbon,and circular development system.
