Air disinfection method and a device for implementation thereof

Abstract

The invention relates to methods for air disinfection of microorganisms and biological agents by the method of their inactivation by electrostatic fields and filtering by the method of electrostatic precipitation. The method comprises the steps of creating a flow (A) of air to be disinfected; subjecting said flow to constant with electrostatic fields alternating in direction of intensity vector, said electrostatic fields being sequentially arranged along the flow, and created by transversely spaced air permeable electrodes (); and filtering the treated flow with an electrostatic filter. Electrostatic field concentrators in the form of projections () are located on the surface of the electrodes (), in particular nanoscale projections, and the intensity of each of the alternating electrostatic fields between the electrodes is selected in accordance with the condition of electroporation of microorganism cells or their inactivation. A device for implementing this method is also claimed. The use of the invention provides a fast, effective, and reliable cleaning of air from any kind of microorganisms and viruses, as well as the aerosol particles having size of 0.08 μm. The invention also provides improved hygienic safety due to microorganism inactivation before the filtration step, and because of the absence of dangerous concentrations of ozone and other harmful substances.
