INJECTOR FOR SPRAYING LIQUID IN GASEOUS ATMOSPHERE Russian patent published in 1999 - IPC

FIELD: devices for spraying liquids in flow of gas (air); cleaning of gas; ventilation and air-conditioning systems; heat and moisture treatment of air in sprinkling injector chambers on central air conditioner to increase degree of dispersion of liquid in gaseous atmosphere. SUBSTANCE: injector has housing with cylindrical axial passage for liquid; washer-bush with calibrated orifice is fitted at this outlet. Located coaxially after bush has ejector member made in form of Venturi tube having inlet part-confuser, center cylindrical part - neck and outlet part - diffuser. Edges of diffuser have triangular cuts and are framed over perimeter. Through cylindrical passages are located over perimeter of confuser in parallel with its axis. Hollow cylinder - guide device is mounted on the outside of diffuser coaxially relative to its outer surface. Structurally, guide device is made integral with nut used for assembling and securing the injector elements. Dispersion of water flow is effected due to the following three facto: translational and rotary motion of water and dispersion effect of gas jets ejected by water jet from gas flow. EFFECT: increased degree of dispersion of liquid in gaseous atmosphere. 2 cl, 1 dwg
