ABSTRACT:
A flood beam electron gun is provided for use in remediation of hazardous volatile organic compounds (VOC) contained within a detoxification vessel. The flood beam electron gun comprises an electron emitter having a rounded emitting surface providing a conical electron beam. A control grid is spaced from and disposed substantially parallel to the emitting surface. The control grid has a plurality of holes disposed in a first pattern providing an array of individual electron beams from the conical electron beam of the emitter. An intermediate electrode is spaced from the emitter and the control grid, and has an aperture therethrough providing a substantially parallel flow of the array of individual electron beams. A target grid is spaced from the intermediate electrode and opposite from the cathode and control grid. The target grid has a plurality of holes disposed in a second pattern that is proportional to and substantially larger than the first pattern. Each of the individual electron beams pass through respective ones of the plurality of holes in registration thereof. A vacuum barrier is provided on a downstream side of the target grid to separate the electron gun from the vessel. The individual electron beams pass through the vacuum barrier into the vessel. Within the vessel, the electrons of the individual beams impact the VOCs, converting the VOCs to less hazardous organic compounds.
