Decomposition cell
A decomposition cell having a first metal plate with a first layer of dielectric and a second metal plate with a second layer of dielectric wherein each layer of dielectric is sprayed onto the metal plates in molten form using a thermal plasma spray process. The plates are placed in parallel spaced relation forming a discharge area therebetween. One of the metal plates is then attached to a high voltage high frequency source that when actuated causes a discharge within the discharge area.
1. A flow-through decomposition unit comprising a plurality of parallel plate decomposition cells, assembled in a honeycomb configuration between first and second side walls, and separated from one another by insulators, wherein each decomposition cell comprises:
a first metal plate having first layer of dielectric material;
a second metal place in parallel spaced relation to the first metal plate and having a second layer of dielectric material thereon to form a discharge area between the first and second metal plates, wherein the first layer of dielectric material and the second layer of dielectric material face one another, and together form a plurality of flow path discharge areas.
2. The decomposition unit of claim 1 wherein the first and second metal plates are made from copper.
3. The decomposition unit of claim 1 wherein the first and second layers of dielectric material are made from alumina.
4. The decomposition unit of claim 1 further comprising a high voltage source electrically connected to the first metal plates.
5. The decomposition unit of claim 4 wherein the high voltage source is a circuit integrated into the first metal plates.
6. The decomposition unit of claim 1 , wherein the first layer of dielectric material and the second layer of dielectric material are applied by spraying a molten dielectric material onto surfaces of said metal plates.
7. The decomposition unit of claim 6 wherein the molten dielectric material is doped with magnesium.
