Abstract

The invention discloses a magnetic-control high-voltage electromagnetic atomizing device. The magnetic-control high-voltage electromagnetic atomizing device comprises a liquid storage tank, a metering pump, a liquid conveying guide tube and a spray nozzle, wherein the suction end of the metering pump is connected to the liquid storage tank through the liquid conveying guide tube; and the output end of the metering pump is connected to the spray nozzle through another liquid conveying guide tube. The spray nozzle comprises an atomizing site, an atomizing electrode, a reference electrode, a voltage source, a direct-current voltage source and a superconducting coil. According to the device, the atomizing electrode of the spray nozzle is wrapped up by an insulating sleeve, and only the top part of the atomizing electrode is needed to be exposed, so that the ionization effect of the liquid is strengthened; electromagnetic coils are arranged, so that one magnetic field perpendicular to the direction of electric fields is formed in an electric field area; electrons emitted by the atomizing electrode move under the action of electric field force, and also bear Lorentz force from the magnetic field, so that the electrons move along a spiral path in a process of moving to the reference electrode from the atomizing electrode, the acting path, in the liquid, of the electrodes, is increased, namely, the previous linear motion from an emitter electrode to the reference electrode is changed into current spiral motion under the action of the Lorentz force.

Description

technical field [0001] The invention relates to a magnetically controlled high-voltage electrostatic atomization device. Background technique [0002] A large number of studies have shown that charging can reduce the surface tension of the liquid and the atomization resistance, and the droplets with the same charge will be broken into smaller droplets under the action of the electric field force, and the diameter distribution of the droplets will become more uniform. Static electricity increases the control parameters of the atomization flow field, that is, in the case of certain parameters such as flow rate, pressure, and nozzle diameter, the atomization flow field (such as droplet size, atomization angle, range, droplet size, etc.) can be controlled by changing the parameters of the electric field. running trajectory, etc.) play a certain role in regulation. Electrostatic atomization has been widely used in many aspects such as pesticide spraying, industrial spraying, mat...
