AIR DISINFECTION DEVICE Russian patent published in 2014 - IPC F24F3/16 

FIELD: ventilation.

SUBSTANCE: invention refers to disinfection devices. An air disinfection device including a housing having an air intake compartment with an inlet opening and an outlet compartment with an outlet opening, between which there is an irradiation chamber separated with labyrinth partition walls-screens, in which there installed are lamps and a power supply unit electrically connected to a control and indication unit; a filter element is arranged in the air intake compartment, and a fan is installed in the outlet compartment; besides, the housing is made in the form of a thin-wall box-like body from bactericide polymer plastic with bacteriostats, which consists of two semi-housings connected along the perimetre; gas-discharge mercury lamps are fixed with a gap on bosses; longitudinal axis of the above lamps is offset relative to a connection-disconnection plane towards another semi-housing; on the side of the irradiation chamber, symmetrically located central transverse plates are attached to the base of each semi-housing and have folds on edges, which are directed towards the corresponding compartment, and on the side of each compartment, two side transverse plates are oppositely attached in one plane to the base of each semi-housing and to side walls and have folds on edges, which are directed to the irradiation chamber, the distance between which is less than width of central transverse plates, which is less than width of transverse size of the housing; when attaching the semi-housings, the central plates form labyrinth screens with partition walls.

EFFECT: invention allows improving efficiency of bactericide air disinfection using ultraviolet irradiation.
