Treatment System Comprising a Dielectric Barrier Discharge Lamp

摘要

A treatment system or treatment reactor ( 1 ) comprising at least one dielectric barrier discharge lamp ( 2 ) with a first electrode ( 20 ) and a housing ( 10 ) for containing a medium ( 3 ) like a fluid and/or a gas and/or a solid material which is to be treated by means of the radiation generated by the lamp ( 2 ) is disclosed which is especially characterized in that at least one second electrode of at least one lamp ( 2 ) is provided in the form of at least one intermediate counter electrode ( 3, 4 ) which is positioned within a volume ( 31 ) between at least one dielectric barrier discharge lamp ( 2 ) and the housing ( 10 ). By this, influences of the treated medium on the electrical behavior of the treatment system or reactor ( 1 ) and especially power losses in the medium can be avoided or considerably be decreased. Furthermore, losses of the lamp light due to absorption and/or shadowing at an outer electrode surrounding the lamp are avoided as well.
