The change from large to small diameter results in a large increase in the liquid's velocity, which in turn causes the stream of liquid exiting the nozzle to become unstable and to break up into small drops. The liquid, which can be under pressure or drawn into the nozzle by siphoning, is introduced into an air or gas stream and sheared into drops by the energy contained within the gas stream. This produces drops that are finer than can be achieved with hydraulic nozzles. Ultrasonic Nozzles are electrically driven and operate on an entirely different principle. A titanium nozzle body vibrates at ultrasonic frequencies, driven by an electronic power generator.
Higher frequencies produce smaller drops.
The atomization process is virtually unpressurized. Industrial Tank-Washing Nozzles for the efficient cleaning of processing and storage tanks with a minimum of effluent. We offer a wide variety of nozzle configurations to fit specific applications. Spray Dry Nozzles for excellent performance in spray drying, in both large and small scale applications. Evaporative Cooling Lances for quenching hot gases in a variety of applications, including combustion and chemical processing.
