Description

Aerosol atomizing device

Technical Field

The invention belongs to the technical field of high-pressure devices, and particularly relates to an aerosol atomization device.

Background

Rayleigh proposed in 1882 that the charged droplets were stable under the condition that the charge did not exceed a certain level, and above that the droplets did not remain stable and were broken into droplets. This value is referred to as the Rayleigh limit.

The concept of limit charge proposed by Rayleigh lays a foundation for the research of electrostatic atomization mechanism. Zeleny in 1915 introduced in his research report that adjusting the charge-to-surface tension ratio of a liquid can destabilize a small liquid column at the nozzle tip and break up into ions or droplets. He notes that a more uniform droplet is continuously obtained as long as it is ensured that the force of the supplied electric field is adapted to the amount of liquid to be atomized.

In 1925, wilson and Taytor discovered another phenomenon of atomization due to electrostatic force, i.e., a soap bubble without charge would break up in a strong electric field, breaking up into small droplets.

In 1931, Macky studied the behavior of uncharged water drops with the radius of 0.085-0.26 cm under the action of a uniform electric field, and found that the water drops are elongated along the direction of the electric field under the action of the electric field force, the two ends of the water drops become sharp, and filaments are pulled out from the tips of the water drops.

On the basis of the discovery of Rayleigh, chinese patent application No. CN100475353C discloses an electrostatic atomizing apparatus, comprising: the water supply device includes an emitter electrode, an opposite electrode opposite to the discharge electrode, a water feeder configured to supply water onto the emitter electrode, and a high voltage source configured to apply a high voltage to the emitter electrode and the opposite electrode, thereby electrostatically charging the water on the emitter electrode by applying the high voltage and ejecting charged water particles from a discharge end of the emitter electrode. The water feeder of the electrostatically atomizing device is configured to condense water in the ambient air on the emitter electrode, so that water can be supplied to the emitter electrode in a short time without depending on an additional water tank. Therefore, the charged minute water particles can be immediately atomized by using the device. The electrostatic atomization devices following the aforementioned patents continue to take water and charge the water.

The electrostatic atomization device disclosed in the above-mentioned patent publication and later needs to be equipped with a water supply unit, which is a separate water tank or water generated by condensation, and thus the structure is more complicated, the manufacturing difficulty is increased, and the cost is increased. The electrostatic atomization apparatuses disclosed in the above-mentioned patent publications and those described later require an additional charge to condensate water or the like, and further complicate the structure.
