In Japanese Patent No. 413G32, it is proposed that-- The waste generated from hospitals is kept in a sealed storage and is treated with other waste materials—a method of dissolving with a metal dissolving furnace as a waste material treatment method. In Japanese Patent Publication No. 5-69596, another proposal is to pulverize infectious medical waste by a pulverizer and mix it with a gas adsorbent generated from infectious medical waste in a blender, and then heat it with a temperature of 180 ° C or more. A device for manufacturing bone material for building materials from infectious medical waste is regarded as a device for manufacturing bone material for building materials from infectious medical waste. [Problems to be Solved by the Invention] It is known that in the treatment of medical waste, in order to completely sterilize infectious pathogenic bacteria, these infectious pathogenic bacteria are completely heated at a heating temperature of 180 ° C or higher for a predetermined time. The treatment method for killing is approved by the Ministry of Health, Labour and Welfare (Ministry of Health of Japan). Therefore, in the treatment of medical waste, the heat treatment of related infectious pathogenic bacteria is necessary. Therefore, the conventional medical waste treatment method is generally treated by sterilizing and burning by heat treatment, and then burying ashes in the ground. However, this medical waste must be made of plastic materials, such as syringes, medicaments, gold liquid preparations, and discarded sealed containers. Because plastic products must be used, the conventional heat treatment and burn-out treatment apply medical waste to the paper size.

Description of the invention (3) The printed materials of the consumer cooperatives of the employees of the Intellectual Property Bureau of the Ministry of Economic Affairs can be directly or sealed in a container for heating treatment or incineration treatment as usual. Μ Heating and incineration in oxygen, so this type of medical waste must be used in plastics, especially in chlorine-based plastics. No matter the heat treatment or burning treatment of any device is used, there is a problem that the dioxin formation of organic gas compounds cannot be completely ruled out. . In particular, dioxin, an organochlorine-based compound, is a widely used plastic worldwide. Especially chlorine-based plastics are accused of being the biggest cause of substances that damage the modern social environment, and very small amounts can also become carcinogens in humans. It is severely restricted internationally, but it is known that it is impossible to completely eliminate the problems that can cause dioxin in the air and oxygen environment. In the post-use injection container treatment method of Japanese Patent No. 3-31515, the post-use synthetic resin injection container and injection needle are stored in a heat-resistant container 'and heated and dissolved and sterilized in a heating furnace at 18 (rc to 20 (rc or more) Therefore, infectious pathogenic bacteria can be sterilized by heat treatment. However, chlorine-based synthetic resins such as vaporized vinyl resins used as synthetic resin injection containers are generally used because of heating and dissolving. There is a problem that toxic substances such as dioxin cannot be removed. In the waste treatment method of Japanese Special Fair No. 4-13032, medical wastes and wastes are subjected to a waste preheating project and then dissolved by a metal dissolving furnace or directly in a metal dissolving furnace, so it cannot be completely removed. During the preheating of waste materials or in the metal dissolution furnace during the heat treatment, toxic substances such as dioxin produced from gas and plastic, and impurities generated by medical waste are mixed into the dissolved material in the metal furnace that has not been easily dissolved.

Description of the invention (14) After 300 hours in a secondary heating furnace, The temperature was gradually raised to a heating temperature of 500 ° C for 2 hours. In this heat treatment project, the hydrogenation reaction of gas-based plastics such as vinyl chloride resin (PVC) contained in medical waste (evaporation of gas and gas components in the resin) will occur at 200 ° C to 300 ° C. A well-known experimental example knows that by heat treatment at a heating temperature of about 300 ° C, more than 99% of the hydrogen chloride of chlorine-based plastics will be removed, so the 300 ° C is the heating limit. The primary heating furnace continued to heat-treat for 2 hours at a heating temperature range of 300 ° C, because if the previous stage was sterilized and dried in the heating furnace, the plastics in the heat-treatment process were dissolved in the heat-treatment process but failed to anneal in the moon. The moisture is completely evaporated and there is residual moisture. I am afraid that the gas generated by the gasification hydrogen reaction of gas-based plastics will combine with moisture to form hydrochloric acid. I am more worried about dioxin. Therefore, from 180 ° C to 300t: This method completely evaporates the moisture of resin annealing, and completely eliminates the risk of generating hydrochloric acid and dioxin. In all the heating furnaces used in the heating treatment project of the present invention, since the inert gas is continuously supplied with nitrogen, the gas generated in the heating treatment project is continuously discharged, and the heating treatment is performed at the same time, that is, all the heating furnaces will be filled with inert gas. Heat treatment in nitrogen environment, so there is almost no residual oxygen in the heating furnace and it becomes a very low-oxygen environment, and the combination of oxygen and gas in the heating furnace will rarely generate hydrochloric acid. When it is completely evaporated, the vaporized moisture and gas of the resin annealing in the heating furnace will be directly combined, and hydrochloric acid or dioxin may be generated. Therefore, the internal moisture evaporation of the resin annealing will still be performed at this stage (please read the precautions on the back first) Page) Packing _ Line-This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) 313277 14 531626 A7 V.

The medical waste was heated in the primary heating furnace at a heating temperature of 30 ° C for 2 hours, and then gradually heated up in a secondary heating furnace at a heating temperature of 300 ° C to 50 ° C and 50 ° C. The heating temperature is continued for 2 hours. Μ The secondary heating furnace uses a heating treatment at a heating temperature of 50 (rc) to thermally decompose the oily components of the plastics contained in the medical waste, and the oily components are based on The material is separated and recovered, and the residue is carbonized. Above about 340 C will cause the main chain cutting reaction of the chemical bond of vinyl chloride resin (PvC), and the decomposition gas containing petroleum components will occur, except for special resins such as rubber and nylon, Most thermoplastic resins will decompose at 500 ° C. Undecomposed residues remain in the heating furnace for carbonization. The lignin of lignin series begins to decompose at 280 ° C, and the decomposition is increased at 370 ° C, and continues to 500 ° C. However, the woody system started to carbonize from 40 ° C, and most of the woody materials were carbonized at 500 ° C. These secondary heating furnaces are generated from plastic materials contained in medical waste due to thermal decomposition of heat treatment. The oil component gas will be discharged to the outside of the heating furnace together with nitrogen. After cooling and removing the oily components with a Dirham condenser (oil separation material), it will be harmful by a well-known scrubber (exhaust gas removal device). The gas is completely removed, and only the harmless inert gas nitrogen is released into the atmosphere.

Then in the second stage, the tray is placed on the discharge conveyor, and it is left at room temperature for 1 to 2 hours. And cooling. The first stage of cooling should be at 200 ° C to 30 ° C for more than 1 hour, because in an oxygen environment, 300 ° C to 320 ° C will generate a maximum of dioxin, and 250 ° C will not increase the production of dioxin. 20 (rc will decrease, but when sprayed with gas, 'Diocin will decompose at 300 ° C (a well-known fact based on experiments by Swedish Labei et al.).

In the secondary heating furnace, most of the medical waste contained in the wood-based substances will be decomposed and gasified. The oily components contained in the decomposed gas are discharged from the filter dust collection device that collects oil mist, wet mist and high-temperature dust. Nitrogen is removed, it will not be adsorbed in the absorption tower, and the gas left in the water tank may generate hydrochloric acid. Therefore, it is necessary to periodically perform a pH test and add an alkaline solution to neutralize it. The oily components produced by the decomposition and decomposition of plastics are heated. Although the recovered oily components are mixed with wood-based and petroleum-based decomposed oils, it is difficult to separate them based on the components and they may contain harmful substances, so they cannot be used directly as heavy oil. And other alternative oils, and because it is a dangerous acid oil mixed with light oil with low ignition point, other chemical processing equipment must be used as fuel, and sometimes it must be treated as waste oil. Although mussel-based oily components (pyanoic acid-like) are recovered, in general, pyromylic acid is natural and harmless. When analyzing thermally decomposed gases, a variety of harmful chemicals will be detected. 'Sometimes they will become strongly acidic liquids. It is a tree, and the components of the recovered woody oily component (pyanoic acid-like) also vary depending on the carbonization time or carbonization temperature, and carcinogenic substances are also excreted in it. Therefore, the woody oily component (pyronic acid-like) It cannot be reused as such. The decomposed gas is cooled by a condenser, and is divided into a liquid substance and a gaseous substance. The liquid substance is an oily component. The plastics of medical waste, except ethylene chloride resin, will be gasified in this project. Because the liquid (oily component) and gas cannot be completely separated during cooling, the gas is again impacted and separated in the dust collecting device formed by the honeycomb filter.
