Abstract

The invention discloses a high-flow ultrasonic fine atomization nozzle, and relates to an atomization nozzle. The high-flow ultrasonic fine atomization nozzle aims at solving the problems of non-uniform particle size distribution and non-uniform space distribution of the existing high-flow wet saturated steam water drops. The high-flow ultrasonic fine atomization nozzle disclosed by the inventionis composed of an outer ring of the nozzle, centrifugal nozzles, an ultrasonic generator and a nozzle body, wherein high-pressure water is sprayed out from the outlets of the centrifugal nozzles to form primarily-atomized water drops; auxiliary atomization steam enters the nozzle via an auxiliary atomization steam through hole in the nozzle body, and generates high-frequency resonance with the primarily-atomized water drops at a resonant cavity to form secondarily-atomized water drops with uniform particle sizes; and the steam is adequately mixed with the finely-atomized water drops to form wet saturated steam meeting the requirements. 25 small centrifugal nozzles are circumferentially arranged in the nozzle disclosed by the invention, and carry out mist spray, atomization and diffusion simultaneously, so that the problems of non-uniform particle sizes and non-uniform space distribution of water drops in the traditional method for preparing wet steam are effectively solved. The high-flow ultrasonic fine atomization nozzle disclosed by the invention is applicable to preparation for the high-flow wet saturated steam.

Description

technical field [0001] The invention relates to an atomizing nozzle. Background technique [0002] In many fields of modern industrial production and national defense construction, such as petrochemical, pharmaceutical, printing and dyeing, steam power and other industries, wet saturated steam has a wide range of applications, often in these fields require large flow and fine atomization particle size Wet saturated steam to ensure production quality. Especially in the field of wet steam research, so far there is no effective method to prepare wet saturated steam with known humidity and particle size, and to carry out in-depth research and calibration on some test devices and humidity measurement devices. At present, the preparation of large-flow wet saturated steam is generally achieved by reducing the temperature and pressure of superheated steam, but the wet steam obtained from this has the disadvantages of uneven particle size distribution and spatial distribution of wat...
