Static Electricity dust collect principle

(1) To use the positive and negative electrode to attract to each other for static electricity dust collect. To use AC high voltage electricity to through the rectification, and then the positive and negative electrode will generate the high strength power static magnetic field. One of the electrode(Line shape) which has large surface curvature is discharge electrode. Another electrode (Plate shape) is dust collect electrode. To connect the discharge electrode to the power ( negative), and dust collect electrode to the power(positive). Between two electrode will generate a electric field. The ion in the air which exist in the field will move to two electrodes to create the electric current. When the voltage increase the current will variable as different stage. The ion will raise speed when the voltage increase and then reach to the saturated status. When the voltage continuous increase to V0. The surface which discharge electrode will generate the purple ring of light and has sound ( s---). Lots of electron which around the electrode will spread. This is electric halo discharge electricity

(2) Because of the electric halo discharge carry with lots of negative ion to move from discharge electrode to dust collect electrode, and the dust will carry with the electricity. The dust which carry with electron generate by electric field coulomb power to move to dust collect electrode. The dust which reach to the dust collect electrode will lose the electric charge and attach with the dust collect electrode. Because of the posative ion will move to discharge electrode. The moving path is shorter, so it can only match with a few dusts to make it carry with electron. Therefore only a few dust will be attach with the posative electrode. This is how the air clean works. The dust which inside the dirty air will be catch to dust collect electrode to make sure the air-clean procedure complete. The dust will be fall by gravity, but also needs to strike the dust collect plate to release the dust into design collect dust case.

(3)  If the discharge electrode connect with negative electrode, then it will generate the negative electric halo. Reverse will be generate the positive electric halo. In the normal condition the negative voltage will be lower and the current will be higher than positive electric halo. Therefore the the negative electric halo usually use in the industrial. But the positive electric halo has to drive by more power. But the ozone increase quantity only 10% than negative electron discharge. Therefore for human health, the indoor air cleaner usually use positive electron halo as static electric discharge dust collector.
