Embodiment 1
[0049] According to the above process, this embodiment provides a high-temperature pyrolysis polyoxygen incineration treatment system for medical waste. This system utilizes the residual energy of liquid oxygen refrigeration commonly used in hospitals to make the medical waste storage tank into a storage tank with a freezing function (-10°C The following), on the one hand, reduces the activity of germs, on the other hand, the collection is timely, does not involve transportation and storage, and reduces costs; through the design of a crushing mechanism at the lower part of the garbage storage box, the frozen medical waste is crushed and sterilized with ozone; Automatic screening, to separate a very small amount of metal, glass and other sundries among them, and then discharge the system after further high-temperature steam sterilization, and then dispose of it separately; the medical waste that has been crushed and sterilized by ozone is airtightly transported to the anti-burnin...

The invention provides a high-temperature pyrolysis and oxygen-rich incineration treatment process and system for medical waste. According to the process, the medical waste is crushed after being frozen, and then is screened; during screening, inorganic matter-like substances in the medical waste are separated, and are discharged after being sterilized; reversal combustion gasification and oxygen-rich incineration is performed on remaining organic matter; waste heat utilization is firstly performed on produced gasified gas, and low-pressure steam generated by waste heat utilization is used formedical institutions, and produced low-temperature flue gas is used for performing backflow regulation on the oxygen-rich concentration of reversal combustion gasification and oxygen-rich incineration; ash and slag disposal is performed on solid products of reversal combustion gasification and oxygen-rich incineration; and oxygen during reversal combustion gasification and oxygen-rich incineration is supplied by surplus oxygen in a liquid oxygen production link. The process system provided by the invention has the characteristic of distributed miniaturization, is quickly started and stopped,is ready to start and use, can stop at any time, and reasonably utilizes surplus cold energy in gasification of liquid oxygen of a hospital, reasonably utilizes energy, meets the oxygen demand for oxygen-rich incineration, and is a distributed comprehensive utilization system for waste of comprehensive medical institutions.
Description
technical field [0001] The invention relates to medical waste treatment, in particular to a high-temperature pyrolysis method for treating medical waste. Background technique [0002] In the operation of medical institutions, a large amount of medical waste will be generated, forming solid waste that may contain bacteria, viruses, and pollutants. Governments of all countries attach great importance to the classification, storage, transportation, and disposal management of medical waste. [0003] Medical waste mainly refers to the garbage and waste materials generated in the whole process of medical treatment, mainly composed of plastic, waste paper, kitchen waste, wood and bamboo, fiber, leather, rubber, surgical resection, glassware, etc. Most of these wastes are organic hydrocarbons, which can be completely burned into ashes under certain temperature and sufficient oxygen conditions. After medical waste is incinerated, it can not only completely kill bacteria and viruses,...
