PROCESS AND DEVICE FOR THE THERMAL DESTRUCTION OF WASTE

摘要

A process and device are proposed for the thermal destruction of waste on the surface of a bath of molten metal and slag through heating in plasma streams and passing the waste gases through the molten metal. The procedure involves the creation of a plasma sleeve in the area where the waste is introduced, the said sleeve isolating the introduced waste from any contact with those parts of the equipment to be cooled. This arrangement facilitates the safe destruction of bacteriologically dangerous and highly toxic waste. The plasma sleeve is created by a coaxial plasmatron provided with a hollow central electrode through which waste is introduced. In addition, means are provided for carrying out systematic bacteriological monitoring of the products recycled from the waste where it comprises septic waste from medical and veterinary establishments.
