LOW PRESSURE LOSS/ REDUCED DEPOSITION ATOMIZER

摘要

An atomizer for discharging a jet of one fluid in another fluid, comprises a nozzle head having at least one nozzle hole therein for discharging the jet. The nozzle hole has an inwardly tapering inlet end and an outwardly tapering outlet end for reducing recirculation and wetting at the exit of the hole. The outlet end tapers at an angle of no greater than 14.degree. and the inlet end is advantageously curved at a radius which is from 2 to 10 times the diameter of the inlet end. The diameter inlet end should also be from 1 to 5 times the length of the hole.
