Two-fluid atomizing nozzle

The utility model discloses a two-fluid atomizing nozzle which is used in a spraying drying device. The two-fluid atomizing nozzle comprises a distribution base and a spraying nozzle; the distribution base and the spraying nozzle are fixed through a nut; an adjustable spraying core is arranged between the distribution base and the spraying nozzle; distribution of feed liquid is achieved through the spring core. According to the two-fluid atomizing nozzle, increasing of feed liquid spraying angles is achieved through the spraying core, so that the atomizing diameter is large, the granularity reduces, instant drying is generated when the feed liquid is in contact with hot air, the small water content is achieved, heat exchanging between fog drops and the hot air is full, and sticking and caking are prevented.
