Static eliminator principle: static eliminator can also be called de-static equipment
Principle is as follows
It consists of a high-voltage power producer and discharge electrodes (usually made of ion needles), through the tip of the high-voltage corona discharge will be ionized into a large number of positive and negative ions of the air, and then a large number of positive and negative ions blown to the surface of the object to neutralize the static electricity, or direct neutralization of the static electricity.
Static electricity eliminator is mainly divided into the following types:
1, AC corona products AC high-voltage producer 220V input voltage rises to more than 4KV, 50 discharge electrodes Hz frequency alternating positive and negative voltage, discharge electrodes and grounding poles to produce a strong electric field between the air molecules ionization, discharge electrode tip alternately produce positive and negative ions. When the surface of the charged object is positive potential, negative ions are neutralized. Conversely, if the surface is negatively charged, positive ions are neutralized. AC Corona products must be grounded to work properly, but some positive and negative ions can cause grounding, but the structure is simple with a good balance of positive and negative ions.
2, DC corona products DC high-voltage producer 220V input voltage rises, respectively, the output of positive and negative voltage, positive and negative discharge electrodes between the generation of a strong electric field, air molecules ionization, positive discharge electrode tip produces positive ions, negative discharge electrode tip produces negative ions, positive and negative ions neutralization of static electricity on the surface of the object, the negative ions and if the surface of the negative potential, the positive ions and neutralization. No need to ground, DC corona products can produce positive and negative ions, the role of positive and negative ions on the surface of the object is sufficient to neutralize the electrostatic speed is very fast.
3, pulsed DC corona products pulsed DC high-voltage producer 220V input voltage rises, in the discharge electrode output positive and negative voltage 4-6 seconds, alternately produce positive and negative ions. When the surface of the charged object is positive potential, negative ions are neutralized. Conversely, if the surface is negative potential, positive ions are neutralized. Because the switching cycle of pulsed DC positive and negative ions is 200-300 times longer than that of the industrial frequency alternating current electrostatic eliminator, the positive and negative ions themselves will not be neutralized, the positive and negative ions do not need to be grounded and lost, and the switching cycle can be adjusted according to the distance of the static electricity object. Pulse DC static eliminator can also reach a long distance with positive and negative ions without a fan.
