Abstract:
1. An apparatus for the inactivation and fine filtration of viruses and microorganisms in an air flow comprising a high-voltage power supply ( 4 ) and, in series along the air flow: an air flow pretreatment means ( 1 ) formed of oppositely charged current-conductive filtering units ( 7 , 7 ′) with a plate ( 5 ) made of a permeable high-porosity insulating material installed between the filtering units; a two-compartment inactivation chamber ( 2 ), each compartment whereof being embodied as a needle corona electrode ( 12 ) and a cylinder non-corona electrode ( 10 ) arranged coaxially to each other and each being electrically connected to the corresponding plate ( 13 ) made of a current-conductive filtering material; and a precipitator ( 3 ) embodied as oppositely charged plates ( 14 ) arranged in parallel to each other and made of a high-porosity current-conductive material, with plates ( 15 ) between them made of a permeable high-porosity insulating material, the apparatus being characterized in that: at least the first (along the air flow) current-conductive filtering unit ( 7 ) of the pretreatment means ( 1 ) is embodied as a cylinder electrode ( 6 ) having a base in the form of a plate ( 7 ) made of a permeable porous current-conductive material and positioned adjacent to the plate ( 5 ), which is made of a permeable high-porosity insulating material, and a plate ( 9 ), which is made of a high-porosity current-conductive material, arranged at a distance from the free end of the cylinder electrode, and to which adjacent is a needle electrode ( 8 ), the electrode 8 being electrically connected to the plate ( 9 ), being arranged coaxially to the cylinder electrode ( 6 ), and having its point directed toward the insulating plate ( 5 ), wherein the cylinder electrode ( 6 ) and the needle electrode ( 8 ) are connected to the opposite poles of the power supply ( 4 ).
