Abstract:
An apparatus for plasma treatment of gas for transformation, passivation and stabilization of polluting and toxic admixtures, comprising generator means, particle filter means, solid state catalyst means and means for heating and/or cooling, whereinthe apparatus comprising at least one hollow cathode connected to a first means for heating and/or cooling, the hollow cathode having a length longer than a distance between opposite facing walls and being disposed for generation of a hollow cathode discharge plasma by means of the generator means connected to the hollow cathode and to a counter electrode, the counter electrode further being disposed as an inlet means of a flowing gas to be treated in said hollow cathode discharge plasma generated in this flowing gas;the particle filter means is connected to a second means for heating and/or cooling being disposed in said counter electrode for filtering the flowing gas to be treated, said particle filter means being installed upstream said flowing gas before the hollow cathode and a quenching electrode connected to a further means installed downstream a transformed flowing gas after the hollow cathode and a solid state catalyst for additional treatment of the transformed flowing gas.
