DEVICE FOR HEAT AND MOISTURE TREATMENT OF AIR Russian patent published in 2012 - IPC F24F5/00 

FIELD: ventilation.

SUBSTANCE: device for heat and moisture treatment of air comprises a mixing chamber, a heater and an irrigation unit, there are two stages, besides, the first stage is a multifunctional device with opposite twisted flows and is designed to clean recirculating air arriving from a room and having positive temperature from dust, and also to moisten air, and comprises a body with a reservoir to collect fluid, where a pump is installed with a filter for fluid recirculation along a pipeline and its supply into the irrigation unit, which is arranged in the form of at least two circular tubular headers with centrifugal nozzles evenly arranged along the inner surface, besides, in the lower part of the body there is a lower input nozzle, and in the upper part - an upper input nozzle, and in the nozzles there is accordingly a lower tangential swirler and an upper tangential swirler, at the same time an exhaust nozzle connects the first stage of the device with the second stage of the device designed to mix air flows arriving from the first stage with a flow of outside air, besides, the second stage of the device is arranged in the form of a heat and mass exchange mixing device and comprises an input nozzle of the mixing chamber, a centrifugal mixing chamber, a diffusor, a confusor, an untwister, an output nozzle, at the same time the body of each nozzle is arranged as hollow, axisymmetric, the axis of which is perpendicular to the axis of the header pipe opening, and the body shape is a solid of revolution formed by a second order curve, for instance, spherical one, in the form of a truncated ellipsoid or a paraboloid of revolution, and at the side of a flow hole of the header pipe in the nozzle there is a straightening element arranged in the form of a ring, comprising a central bushing, with which at least three blades being radially arranged are rigidly connected, being joint with the nozzle body, besides, the body is made with two ledges oppositely arranged perpendicularly to the nozzle axis, and by means of these ledges via yokes with locks the nozzle is fixed on the header, besides, in the lower part of the nozzle body there is a conical throttle opening connected to the mixing chamber, which is installed between the throttle opening and the straightening element, and on the inner surface of the mixing chamber there are helical grooves.

EFFECT: increased efficiency of heat and moisture air treatment.
