Abstract
Thermal destruction of waste includes forming a bath of a melted slag, heating the waste and introducing the waste onto a surface of the bath, passing produced off-gasses through the melted slag, discharging the off-gasses, releasing produced metal and slag from the bath, forming in the closed volume a plasma hose over the surface of the bath by a coaxial electric arc plasma torch by two tubular electrodes located one inside the other, and introducing the waste through an interior of the inner electrode and then through the plasma hose.
Claims7
A method of thermal destruction of waste, comprising the steps of forming a bath of a melted slag in a closed volume;
- heating the waste and introducing the waste onto a surface of said bath;
- passing produced off-gasses through the melted slag;
- discharging the off-gasses;
- releasing a produced metal and the slag from the bath;
- forming in the closed volume a plasma hose over the surface of said bath by a coaxial electrical arc plasma torch with two tubular electrodes placed one inside the other, so that a gap is formed between said tubular electrodes through which a plasma forming gas is introduced to form the plasma hose;
- and introducing the waste through an interior of an inner one of said electrodes and thereafter through said plasma hose.
An apparatus for thermal destruction of waste, comprising a reaction chamber formed as a closed volume with a bath of a melted slag inside;
- and means for forming in the closed volume a plasma hose over the surface of said bath by a coaxial electric arc plasma torch with two tubular electrodes placed one inside the other, so that a gap is formed between said tubular electrodes through which a plasma forming gas is introduced to form the plasma hose;
- and a loading device for introducing the waste through an interior of an inner one of said electrodes and thereafter through said plasma hose, so that the waste is introduced through an inner one of said electrodes and thereafter through said plasma hose.
