Verfahren und Vorrichtung zur Erzeugung von gasförmigen Sauerstoffanionenradikalen unter atmosphärischen Druckbedingungen mit einer aus Kohlenstoffasern bestehenden Ionisationselektrode

摘要

The invention relates to a process and device for generating gaseous oxygen anionic radicals under atmospheric pressure with a carbon fibre ionisation electrode. The aim of the invention is to provide a process and device as described which prevent any damaging contamination by health-threatening by-products of the ionisation process in the ionisation of air or medical oxygen. With regard to the process, this is attained in that uncharged by-products of the ionisation process, like nitric oxide and ozone, are separated by suction from the oxygen anionic radicals generated. In an advantageous embodiment an annular counter-electrode (7) is used which affects the whole region of the ionisation electrode (4) and permits the production of an electric field with defined geometry and voltage. In the device of the invention the aforementioned problem is correspondingly solved in that there is a suction device (11, 12, 13) by means of which the uncharged by-products of the ionisation process can be separated from the oxygen anionic radicals produced.
