Abstract RU 2668032 C1

FIELD: devices for liquid atomization.

SUBSTANCE: invention relates to equipment for liquid atomization and can be used in fire fighting, agriculture, chemical industry and heat power engineering. Vortex nozzle contains a hollow body with a nozzle and a central core. Body is made with a fluid supply channel and contains coaxial, rigidly coupled with body bushing with a nozzle fixed at its lower part, made in the form of a cylindrical two-stage bushing. Upper cylindrical stage of bushing is connected by a threaded connection to a central cylindrical core having a through inner central hole and installed with an annular gap with respect to an inner surface of the cylindrical bushing. Said circular clearance is communicated with, at least, three radial channels made in said two-step sleeve to communicate with circular cavity formed by sleeve inner surface and top cylindrical step outer surface. Annular cavity is interconnected with the housing channel for liquid supply. In central cylindrical core lower part hollow cone swirler is attached. Conical shell of swirler is fixed by means of at least three spokes fixed with one end to the conical shell of the swirler in its upper part, and by other end is in annular groove, made on central cylindrical core inner surface. On the external surface of the hollow cone swirler a screw thread is cut. Diffuser is connected to the end lower part of the bush, coaxially and rigidly connected with the body and with the nozzle fixed in its lower part, enclosing a cylindrical core with a hollow conical swirler fixed in its lower part. At the top of the diffuser, at least three ejection openings are provided.

EFFECT: higher efficiency of liquid atomization.
