Abstract
The invention provides a method and apparatus for generating large quantities of singlet oxygen and/or ozone at unexpectedly high efficiencies. An electron beam generated by a hollow cathode plasma discharge device (HCD) is spread by disclosed means over an electron-transmissive window past which is flowing an oxygen-containing atmosphere at a high velocity.
Claims10
Apparatus for generating ozone, comprising:
- a vessel enclosing a volume maintained at an appropriate subatmospheric pressure;
- a hollow cathode plasma discharge device disposed within the vessel for producing a beam of electrons;
- an electron-transmissive window in the wall of the vessel positioned to receive the beam of electrons and communicating with an oxygen-containing atmosphere;
- means within the vessel for speading the beam of electrons produced by the hollow cathode plasma discharge device over substantially the entire surface of the electron-transmissive window to provide an electron beam density below about 0.1mA/cm.sup.2 ;
- and
- means for moving the oxygen-containing atmosphere past said window and within a suitable distance therefrom at velocities in excess of about 4000 feet per minute.
