<P>PROBLEM TO BE SOLVED: To provide the waste treatment equipment for crushing infectious wastes including substances which are hardly crushed or melted such as metallic pieces, or treating them at high temperature without performing the previous combustion, and to economically prepare an ultra high temperature field suitable for the complete sterilization of the infectious wastes. <P>SOLUTION: This waste treatment device has the primary to tertiary combustion chambers, the waste is heated into small pieces in the primary combustion chamber, the combustible matters is burned to gasify thermal decomposable solid matters and to prepare the molten slag of thermal meltable solid matters in a main chamber of the secondary combustion chamber, and the gasified gas in the secondary combustion chamber is completely burned in the tertiary combustion chamber. The secondary combustion chamber has a sub-chamber for supplying the gasified gas in the main chamber to the tertiary combustion chamber, and an upstream end opening part of the sub-chamber is formed on a furnace wall of the main chamber. The main chamber has a high-temperature oxidant injecting device for injecting high-speed jet flow of high-temperature oxidant into the main chamber, and an injection port of the injection device is formed in adjacent to the opening part of the sub-chamber, so that the high-speed jet flow is injected in a state of crossing the opening part. An in-furnace area of the main chamber is kept at a temperature of 1000°C or more by the heat generated from the wastes. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
