Induction electrostatic atomization nozzle

Abstract

The invention relates to an induction electrostatic atomization nozzle. The induction electrostatic atomization nozzle comprises a nozzle body, wherein the nozzle body is provided with an internal gasflow channel, the liquid flow channel is located at the inlet of a liquid flow channel, and the liquid flow channel is provided with an electrode ring. According to the induction electrostatic atomization nozzle, the electrode ring is arranged at the inlet end of the liquid flow passage, the position of the electrode ring far away from the induction electrostatic atomization nozzle is guaranteed,and thus the electric field intensity at the position of an induction electrostatic atomization spray head is reduced, and the fog drop adsorption phenomenon is avoided to a certain extent.

Problems solved by technology

During the spraying process, because the charge carried by the high-voltage electrode device and the charge of the liquid droplets are different charges, part of the liquid droplets sprayed from the nozzle will be directly adsorbed on the surface of the high-voltage electrode device, and some liquid droplets will be on the surface of the high-voltage electrode device. Under the action of electric charge attraction (external electric field), after going back from the outer space of the nozzle body, it is adsorbed on the outer surface of the nozzle body. This phenomenon that the charged droplets are adsorbed on the surface of the high-voltage electrode device and the outer surface of the nozzle body is called the droplet adsorption phenomenon. It is easy to cause problems such as unstable charging effect, liquid leakage and high-voltage discharge in the electrostatic spray system, forming electrical safety hazards and endangering the safety of operators

At present, some domestic patents have designed a special coating structure such as an insulating layer on the outside of the electrode device to enhance the insulation effect of the high-voltage electrode device, but the impact of the coating structure such as the insulating layer on the external electric field strength of the electrode is very small, and there is no improvement. droplet adsorption
