Description
Technical Field

Background
The atomization device is mainly used for atomizing liquid and then spraying the atomized liquid, and is widely applied to the fields of dust removal, combustion, sand blasting and the like. Generally, the atomization device can be classified into two atomization modes, mechanical atomization and medium atomization according to the atomization principle. Mechanical atomization is self-atomization by means of high-speed jet flow produced by liquid under the action of pressure difference. Medium atomization is achieved by using gas with a certain pressure to form high-pressure airflow so as to break up liquid sprayed out at a low pressure.
In the related art, the medium atomizing device is generally a nozzle having a cylindrical structure, and the nozzle has a liquid passage and a high-pressure air flow passage isolated from each other inside the nozzle. The liquid channel is located in the middle. The high-pressure airflow channel is positioned at one side of the liquid channel. The high-pressure airflow blows out from the high-pressure airflow channel, the liquid is sprayed out from the liquid channel, the gas and the liquid are in cross collision at the outlet, and the atomization is completed after the liquid is collided by the high-speed gas.
However, when the gas pressure is too high, the liquid column flowing out along the liquid passage is easily broken up excessively, resulting in a situation where the liquid is sprayed to the surroundings and becomes hollow at the center of the spray. If the gas pressure is reduced, the atomization is easy to be uneven.
