How does the static eliminator eliminate static electricity?

The static eliminator is composed of a generator and a discharge electrode of a high-voltage power source, and can convert the air ionization into a large number of positive and negative ions through a high-voltage corona discharge at the top, and then can blow the positive and negative ions to the surface of the object by the wind to neutralize the static electricity. There is also the ability to directly neutralize the static eliminator near the surface of the object to neutralize static electricity. The following small series specifically introduces two types of static eliminators:

 

First, AC corona products

1. The AC high voltage generator can raise the 220V input voltage to 4KV or more, the discharge electrode can alternate positive and negative voltages at a frequency of 50Hz, and a strong electric field can be formed between the discharge electrode and the ground electrode, so the molecules in the air will be Ionization, alternating the top of the electrode will have the appearance of positive and negative ions.

 

2. When the surface of the electric object has a positive potential, the negative ion will neutralize it, and if the surface is negative, the positive ions will neutralize it. The AC corona must be grounded to work properly, but some of the positive and negative ions will be directed to the ground due to grounding, but the structure is very simple, and the balance of positive and negative ions is good.

 

Second, DC corona products

1. The DC high voltage generator raises the input voltage of 220V and outputs positive voltage and negative voltage respectively. A strong electric field is generated between the positive and negative discharge electrodes, the air molecules are ionized, positive ions are generated at the tip of the positive electrode, and negative ions are generated at the tip of the negative discharge electrode. Positive and negative ions are simultaneously generated to neutralize the surface of the object. When the surface of the charged object is positive, the negative ions will neutralize. Conversely, if the surface is at a negative potential, the positive ions will neutralize.

 

2. If the object is a DC corona, it can form positive and negative ions without grounding. The function is to make the positive and negative ions on the surface of the object sufficient, and the speed of neutralizing static electricity is very fast.
