Embodiment Construction

[0054] The invention relates to an on-site disposal method of medical solid waste, using the same closed container as a high-temperature and high-pressure reaction kettle and a plasma reactor; the container is connected with a plasma generator, a vacuum device, a steam generator and an exhaust gas purification system.

[0055] First, put the medical solid waste that needs to be disposed into a closed container; start the vacuum device, and when the vacuum degree in the closed container is 3Pa ~ 40Pa, the plasma generator will enter the working state, and the plasma will act for 5 ~ 10 minutes , preferably after 8 to 10 minutes to complete the first sterilization of medical solid waste;

[0056] Then, use a steam generator to send steam into the container to keep the container at 128°C, absolute pressure 250-260p / kPa, and steam density 1.35---1.45ρ / kg·m -3 , after maintaining for 12 to 15 minutes, complete the second sterilization purpose;

[0057] Then, exhaust the air to mak...

Abstract

The invention discloses a medical solid waste on-site handling method. In the method, a closed container which also serves as a high-temperature and high-pressure kettle and a plasma reactor is adopted, and the container is connected with a plasma generator, a vacuumizing device, a vapor generator and an exhaust and purification system. The closed container is used for performing plasma sterilization and high-temperature vapor sterilization. The two means are combined, the two sterilization means act on the medical solid waste in turn, the comprehensive effect of the sequential coordinated actions of the two sterilization means instead of the effect of a single action is achieved, and the final effect is complete due to the complementation of the two means. And the method is particularly applicable to medical solid waste.

Description

technical field [0001] The invention relates to a treatment method for medical solid waste, in particular to an in-situ treatment method for medical solid waste in a hospital. Background technique [0002] The total annual production of medical waste in my country is as high as 680,000 tons [10,11]. Medical waste refers to directly or indirectly infectious, toxic and other hazardous waste produced by medical and health institutions in the course of medical treatment, prevention, health care and other related activities. Medical waste is divided into infectious, pathological, sharps, pharmaceuticals, genetic pollutants, chemical waste and radioactive waste [1]. Medical waste contains a variety of main pathogens that cause infection, such as: bacteria, viruses, fungi, actinomycetes, mycoplasma, spirochetes, chlamydia, rickettsia, etc. Some medical wastes are sampled and tested, and the amount of bacteria in medical wastes is large , the number of Escherichia coli is as high ...
