Air atomizing nozzle droplet size

The air atomizing nozzle can spray mist-like droplets, the diameter of the droplets is uniform and small, so it is often used in spray cooling, spray humidification, spray dust suppression and other fields.

The diameter of the droplets produced by the air atomizing nozzle is changed according to the type of nozzle and the change of the pressure. The diameter of the droplets ranges from 2 microns to 150 microns. First of all, the structure of the nozzle has a great influence on the size of the droplets. For example, the droplets produced by ordinary air atomizing nozzles are generally larger than that of ultrasonic air atomizing nozzles. This is because the ultrasonic air atomizing nozzles are at the gas-liquid mixing nozzle. There is a hat that can generate high-frequency vibration. When the gas-liquid mixture hits the hat, the originally atomized droplets will be further atomized to form a smaller droplet diameter than the original droplet. 40430_2020_2411_Fig15_HTML The atomizing particle size of general-purpose air atomizing nozzles is closely related to air pressure and liquid pressure. They follow the rule that the greater the pressure of compressed air, the smaller the atomized particle size, and the greater the liquid pressure, the atomized particles The larger the diameter. This makes the purchase of nozzles very difficult, because it involves a lot of professional knowledge of nozzle working conditions, so I hope you can tell us the particle size range you need, and we can recommend suitable products for you according to your requirements.
