Abstract

The invention provides a multistage ultrasonic atomizing spraying device. The multistage ultrasonic atomizing spraying device comprises a gas inlet, a plurality of resonating tube structures, a hemispherical focusing structure, a gas-liquid mixing room, a liquid inlet, a guider and a spray nozzle device, wherein the hemispherical focusing structure is arranged in the gas-liquid mixing room. Afterpassing through the resonating tube structures, gas generates ultrasonic waves, and obtains supersonic speed, so that primary atomizing is accomplished in the gas-liquid mixing room. Through the hemispherical focusing structure, secondary atomizing is accomplished. Atomized liquid and gas are mixed to accomplish tertiary atomizing through the guider and the spray nozzle device. The multistage ultrasonic atomizing spraying device is simple in structure, is reasonable in design, adopts a multistage ultrasonic atomizing technology, is good in atomizing effect, and can obtain smaller fog drops with more uniform atomizing particle diameters.

Description

technical field [0001] The invention belongs to the technical field of nozzles, and in particular relates to a multi-stage ultrasonic atomization injection device. Background technique [0002] An atomizing nozzle is a device that disperses liquid in the form of mist. At present, there are various atomizing nozzles, which are widely used in the fields of aerospace, combustion engineering, agricultural irrigation, mechanical processing and chemical industry. At the same time, it is easy to have small droplets dripping, which is caused by insufficient atomization. In addition, there are deficiencies such as difficulty in controlling the atomization effect, uneven atomization, and large atomized particle size. [0003] In the prior art, traditional air atomization nozzles are mainly used. As far as the air atomization nozzles currently used in China are concerned, they are mainly used in working scenarios with large flow rates and large atomization particle sizes. At present...
