Abstract

For the purposes of environmental protection, it is increasingly necessary to remove nitrogen oxides from an air flow at an ambient or outer air temperature. While NO2 can be separated from a gas flow by means of methods known per se, whereby the carbon is washed out or absorbed, it is not possible to separate NO using said methods. Hitherto known methods exhibit deficiencies that make it impossible to use them on a widespread scale. The present invention solves this problem in a simple and inexpensive manner. Short pulses lasting up to a few nanoseconds allow for higher electrical voltages inside the ionizer (4) than direct current, without resulting in electrical flashovers. Tests have shown that ozone is formed inside the gas flow to such an extent that nitrogen monoxide present in said gas flow is substantially oxidized. The NO2 formed in the ionizer can subsequently be removed from the gas flow using a known method. A further advantage of the invention is that a pre-ionizer can be arranged upstream from said ionizer, whereby gas molecules and particles can be electrically charged before they enter the ionizer. The filter system to which claim is laid can also be used without a separator for NO2 for the separation of particles only from a gas flow. One particularly advantageous application of the invention is the use thereof in the removal of smoke, especially smoke emanating from fires, from a flow of air or gas.
