Description

[Detailed description of the invention]

[Industrial Application Field] The present invention stores waste generated from hospitals, clinics, pharmaceutical companies, medical testing institutions, etc. (hereinafter referred to as hospitals, etc.) in a strong metal container with a lid, and stores the waste in a sealed metal container with a lid. The present invention relates to a method for disposing of waste in which the waste is collected and then directly charged into a metal melting furnace together with the container and melted, thereby preventing the waste from coming into contact with the human body. [Conventional technology] Unlike general garbage, waste generated from hospitals, etc. undergoes safe processing such as incineration, cleaning, and sterilization at the hospital, and then either disposes of it themselves as waste, or disposes of it safely. Regarding waste, waste disposal is outsourced to a specialized company that has a disposal license in accordance with the standards of the "Waste Disposal and Cleaning Act" (Act No. 137 of 1970). A common disposal method is to take the container home, remove the waste, and then collect the container again and return it to a hospital or the like for repeated use. [Problem to be solved by the invention] However, in both conventional treatment methods (methods carried out by hospitals, etc., methods in which disposal is outsourced to specialized companies), there is a problem that waste comes into direct contact with the human body during treatment. There is. (This means that B
There is a risk of secondary infections such as hepatitis and AIDS. )
Furthermore, there is a risk that syringe needles and the like may be disposed of by themselves at hospitals, etc., and then handed over to a third party and reused when stored, making storage management difficult. On the other hand, specialized companies also face similar problems during processing after collection from hospitals and the like. In order to solve the above-mentioned problems, the present invention stores waste in a robust metal container with a lid, stores the waste in a sealed manner, and directly charges the entire container into a metal melting furnace, thereby simultaneously storing the waste and the metal container with a lid. The purpose of the present invention is to provide a waste disposal method that is safe and completely controlled during storage by incinerating or dissolving the waste so that the waste does not come into contact with the human body. [Means for Solving the Problems] In order to achieve the above object, the present invention provides syringes (glass, plastic), syringes (metal), drug containers (glass, plastic, metal) discharged from hospitals, etc. Testing equipment, gauze, cotton, bandages, medical equipment (equipment with test material attached, ,
Waste materials (hereinafter referred to as "waste") such as liquids), test samples (urine, stool, blood, tissue), disposable diapers, paper, kitchen miscellaneous goods, etc. are stored in tightly sealed metal containers with lids. The containers in the storage state are collected by a special vehicle, lowered to a designated location indoors using a receiving magnetic crane, a fork lift, etc., and then stored in a metal melting furnace such as an electric furnace (hereinafter referred to as a metal melting furnace). Either directly or by charging the metal container with a lid together with other scrap into a charging scrap bucket using a magnetic crane or the like, and then charging the scrap into the metal melting furnace using the scrap bucket to remove the waste and containers. It burns and dissolves at the same time. Therefore, the metal container with a lid used in the present invention is one
It is not collected and reused in the traditional way.
Furthermore, in order to ensure safe and secure storage, the outer shell of the metal container with a lid is not particularly limited in shape as long as it is made of metal and is robust. The reason it is made of metal is that it also has the advantage of being easier to charge since a magnetic crane is used to charge it simultaneously with other scrap. [Operation] Next, the operation of the present invention will be explained. Type B is used because waste is sealed in a sturdy metal container with a lid and can be collected, transported, and loaded using mechanical means such as a lift or magnetic crane, so it never comes into contact with the human body. Not only can the risk of secondary infections such as hepatitis and AIDS be completely prevented, but metal objects such as syringe needles and drug containers will completely dissolve as they are processed at a high temperature of at least 1400°C. Since other wastes are also burned, they can be completely rendered harmless. [Example] Metal containers with lids for waste collection with iron plate thickness: 0.4 mm, diameter: 30φcm, and height: 36 cm will be placed in each hospital, etc., and waste such as syringe needles will be placed in the containers each time they are generated. I discarded it and stored it with the lid completely sealed with wire. The sealed containers were loaded onto a special vehicle using a lift and recovered. Collected containers will be strictly stored in a designated storage area indoors. The stored containers were loaded into a clam cell-type charging bucket with other scrap metal containers with lids using a magnetic crane, and then heated to 1600 m in a 50T electric furnace.
Conventional melting and refining was carried out at high temperatures above ℃. The loaded syringe needles and other waste materials and metal containers with lids were completely burnt or melted. For reference, we sampled and analyzed the molten steel after tapping, but the amount of waste processed was at most 0.5% or less of the total scrap charge, and no effect on the molten steel composition was observed. . As described above, in the process of the waste treatment method of the present invention, since there is no contact between the waste and the human body, complete detoxification treatment could be established. Table 1 summarizes a comparison between the conventional treatment method for waste generated from hospitals and the like and the treatment method of the present invention.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the following effects. Waste generated from hospitals, etc. is stored in tightly sealed metal containers with lids, and after the containers are collected and transported by mechanical means such as lifts, they are charged into metal melting furnaces by electromagnetic means such as magnetic cranes. rear
Since it is completely burned and melted at a high temperature of 1,400°C or higher, there is no contact with the human body and no residue is generated after treatment, making it possible to perform safe and completely harmless treatment.
