摘要： PROBLEM TO BE SOLVED: To reduce volume of the equipment and also to reduce waste heat by placing electric heaters used as heating means of a combustion furnace in the equipment. SOLUTION: In this equipment, the heating of a carbonization furnace 1 and a combustion furnace 11 is performed with electric heaters 41 and 42, respectively, each of which is controlled by a temp. control device 44, to surely perform temp. control of these furnaces 1 and 11. Also, the amount of air supplied to the inside of the combustion furnace 11 through a combustion air blowing pipe 45, is adjusted so as to correspond to the oxygen concn. of the exhaust gas, to maintain a prescribed oxygen concn. of the exhaust gas and to enable efficient operation. Under such heating conditions, steam in a heat source introducing pipe 9 is supplied to waste 8 that consists of a thermoplastic component and a metal component and is placed within a bucket 7, while spraying the steam on the waste 8 from heat source spray nozzles 10, to carbonize the waste 8. As a result, the thermoplastic component of the waste 8 is melted while being subjected to partial thermal decomposition, and then, falls from the bucket 7 and is withdrawn out of the system. The valuable metal component of the waste 8, such as nichrome wire or brass, remains within the bucket 7 and is separated from the thermoplastic component.

摘要： PROBLEM TO BE SOLVED: To recover a valuable metal(s) from the subject waste composite material by generating superheated steam of a specified temp. or higher in a combustion furnace and heating waste of a composite material consisting of a metal(s) and rubber with this superheated steam as a heat source in the absence of oxygen to subject the rubber to thermal decomposition. SOLUTION: This treatment comprises: introducing superheated steam of >=300 deg.C, generated in a combustion furnace 11, into a heat source introducing pipe 9 placed within a carbonization furnace 1, and concurrently, supplying an exhaust gas generated in the combustion furnace 11 to a space between a furnace wall 2 of the carbonization furnace 1 and a waste receiving chamber 3 placed within the carbonization furnace 1, to heat the waste receiving chamber 3 and a coil 13; and supplying the steam in the heat source introducing pipe 9 into waste 8 that consists of a metal(s) and rubber and placed within a bucket 7, while spraying the steam on the waste 8 from heat source spray nozzles 10, to carbonizing the waste 8 and to subject the rubber component of the waste 8 to thermal decomposition, wherein organic gas generated by this thermal decomposition is completely burned in the combustion furnace 11. At this time, the valuable metal component of the waste 8 remains in the bucket 7 and is separated from the carbonized waste 8. Partly remaining residual carbon on the valuable metal(s) thus obtained, is swept away from the metal(s) and, thereafter, the valuable metal(s) is reused as a metallic material which is not subjected to oxidation and structure change and used for a metallic product.

摘要： PROBLEM TO BE SOLVED: To continuously measure a temperature and a concentration of exhaust gas even in a high-temperature ambiance, by loosely fitting a heatproof pipe in a sensor main body, and supplying cool air into a furnace through a gap between the heatproof pipe and the sensor main body. SOLUTION: A heatproof pipe 13 is loosely fitted from a central part to a base end part of a water-cooled sensor main body 9. The heatproof pipe 13 is fixedly set to a furnace wall 2a. A cool air (b) is supplied into a secondary combustion furnace 2 through a gap 14 between the heatproof pipe 13 and the water-cooled sensor main body 9. Since the sensor main body 9 is cooled by the supplied cool air (b), a cool water (a) circulating in the main body 9 is prevented from boiling, and cooling efficiency from deteriorating. A temperature can be continuously measured by an R thermocouple 11 inserted into a penetrating pipe 9B. The heatproof pipe 13 is preferably formed of ceramic. The heatproof pipe 13 is resistive to damage and deterioration by a high- temperature ambiance, and therefore the temperature and a concentration of exhaust gas can be measured for a further longer time continuously.

摘要： PROBLEM TO BE SOLVED: To control generation of hazardous materials and growth of clinker by providing a mixing tank to mix waste plastics with sludge and a feeding machine to feed the mixture of waste plastics with sludge from the tank into a rotary incinerator. SOLUTION: Pulverized waste plastics A and sludge B are fed into a mixing tank 15 through screw feeders 13, 14 respectively, and stirred and mixed with each other by a stirring machine 18. The mixture C is fed into a rotary incinerator 1 through a third screw feeder 16 and a feeding chute 17, and burned. The temperature in the incinerator is dropped by the heat absorption caused by evaporation of water content in sludge by mixing sludge containing much water with waste plastics of high heat generation, and the rapid thermal decomposition and combustion are controlled. Because the waste plastics are gradually burned, no local deposition of plastics on an inner wall surface of the rotary incinerator 1 is eliminated, and growth of the clinker is prevented.
