Title: Destruction of toxic waste in plasma jet
Inventor: RAYMOND GERALD
IPC: H05H1/42
Filed: 1998-06-22
Abstract: The method involves injecting waste, in fluid form, into the center of a plasma jet against the flow.- DETAILED DESCRIPTION - Fluid (F) to be treated is forced under pressure, at supersonic speed, through a nozzle (3) located on the axis (4) of a plasma jet (2) and directed towards the discharge orifice of a plasma torch (1). The torch produces a symmetrical, concentrated flow with extremely high central temperatures, over 4000 degrees C, in view of which the injecting nozzle is cooled by water circulation. During injection the fluid is vaporized as fine droplets, maximizing the surface area available for heat transfer. Typically, the equipment forms part of a treatment plant for the destruction of chemical warfare weapons, other means being provided for reducing solid wastes. The fluid/plasma mass ratio, in the range 0.1-1, and type of plasma gas are chosen to suit the type of waste, as is the distance (d) of the nozzle from the originating torch, which ranges from 10 to 50 cm with torch powers between 200 and 700 kW. In the complete plant, fluid and solid materials are produced from the weapons material in a detonation chamber. Fluids undergo the plasma process and the solids are heated to recover metals, producing also gases which are further treated to extract pollutants in condensate form
