Device and method for generating an electrical discharge in hollow bodies

摘要

A device and method for generating a physical plasma in hoses of long and simultaneously constricted lumen, flexible or rigid dielectric hoses, tubes or other hollow bodies in the low, normal or overpressure range, which are partially or completely filled or flushed by process medium of gas or gas mixtures, one or more liquids, liquids including gas bubbles, liquid-gas mixtures, aerosols and/or foam, for purposes of cleaning, activating, coating, modifying and biologically decontaminating, disinfecting, sterilizing the inner walls of the hoses or the process medium itself. The device includes a high voltage supply and a process medium supply, at least one electrically conductive grounded electrode and at least one electrically conductive high voltage electrode, both embedded in the wall of the hose.

1. A tubular device, comprising:
an internal tube having dielectric properties and having an inner surface and an outer surface; an external insulation tube enclosing the inner tube; an electrically conductive electrode wire; one electrically conductive grounded electrode wire; a voltage supply; and a process medium inlet; wherein the electrically conductive electrode wire and electrically conductive grounded electrode wire are spatially arranged on the outer surface of the internal tube and/or embedded in the internal tube, the electrically conductive electrode and electrically conductive grounded electrode are covered by the external insulation tube, and when voltage is applied across the electrically conductive electrode and electrically conductive grounded electrode a process medium within the internal tube is converted to a physical plasma.
