AIR FILTRATION DEVICE FOR CLOSED SPACES Russian patent published in 2011 - IPC F24F3/16 

FIELD: power industry.

SUBSTANCE: air filtration device for elimination of biological contaminations for closed spaces, which is connected to outlet air holes in ventilation systems, climate control systems and similar devices and systems, which contains at least one housing in the form of box at least with one inlet hole for filtered air, on which there located is at least one perforated conducting grid having the specified negative electrical potential provided with possibility of electron emission at air flow passage in order to provide negative electrical charge to particles to which microorganisms contained in the air stick; at that, the above device forms from the inside at least one air passage channel that is formed at least between one plate for deposition of negative charged particles to which microorganisms stick; at that, the above settling plate has the specified positive potential, and at least one diverting plate having negative potential and provided with possibility of particle deflection, to which microorganisms stick, at that, electrical field is generated between the above settling plate and diverting plate, which face each other; at that, the above field is intended to divert and deposit particles to which microorganisms stick, on the above settling plate there provided are devices for activation of microorganisms and at least one outlet hole for filtered air. The above grid includes a row of pointed projections for dissipation of electrons when the air flows through the above grid; at that, it contains three settling plates and eight diverting plates; at that, two of the above settling plates are located in upper and lower part respectively inside the above housing in the form of box; at that, each plate faces two corresponding diverting plates located in series; at that, the third settling plate is mainly located on central line in the above housing in the form of box; at that, each side of the above third settling plate faces two diverting plates located in series; at that, the above diverting plates are located in pairs that are located in series between the above settling plates; at that, the above devices for microorganism deactivation include two bactericidal lamps one of which is located between pair of two above diverting plates located in series.

EFFECT: invention allows increasing air filtration, providing complete elimination and guaranteed deactivation of microorganisms.
