How does an electrostatic neutralizer work

Static neutralizer is a static eliminator. The working principle of the static eliminator is: the high-voltage generator and the discharge electrode make a strong electric field between the discharge electrode and the grounding electrode, the air molecules are ionized, the discharge electrode tip alternately produces positive and negative ions, when the wind blows a large number of positive and negative ions to the surface of the object to neutralize the static electricity, or directly put the static eliminator close to the surface of the object and neutralize the static electricity.

The static eliminator is composed of a high-voltage power supply generator and a discharge electrode, which is mainly divided into hand-held contact type, automatic electrostatic eliminator and ion air gun electrostatic eliminator. The use of static eliminator is very wide, mainly used in industrial production, for the film industry, printing industry, plastic industry, packaging industry and so on.

Static neutralizers, also known as electrostatic eliminators, produce electrons and ions. As a result, the charge on the charged body will be neutralized by the opposite charge, thus eliminating the danger of static electricity. According to its working principle, it can be divided into induction, high pressure and radiation.

1. Induction neutralizer.

The tip of the discharge needle has a heterosexual charge under the induction of a charged body, and when a strong electric field appears in space, its field strength exceeds 25 30kV cm, the air is ionized, forming a corona discharge. Anisotropic ions move towards the charged body under the action of an electric field, so that the charge on the charged body is neutralized.

For example, if a synthetic garment is taken off from the body with static electricity, its fibers are erect, and if you approach it with a pin, you can find that the fibers are sagging. This is the phenomenon of electrostatic neutralization.

In addition, the golden top of the Tianzhu Peak of Wudang Mountain is an all-metal ancient building, and for hundreds of years, the surrounding people can see the "fire" at the end of the golden top on thunderstorms, but the golden top is safe and sound. The essence of this phenomenon is the corona discharge neutralization phenomenon that occurs under the induction of charged cumulus.

The induction neutralizer does not need an external power supply, its structure is simple, easy to make and install, and can be used in petroleum, chemical, rubber, textile, paper and other industries.

2. High-pressure neutralizer:

The high-voltage neutralizer is mainly composed of a high-voltage source, a discharge needle, a grounding electrode, etc. Due to the action of the high-voltage source, a strong electric field is generated between the discharge needle and the grounding electrode, and a corona discharge occurs.

Charged ions move directionally under the action of an electric field to neutralize the charge on the charged body, thereby eliminating static electricity. The high-voltage neutralizer has a strong power dissipation effect and is relatively thorough. However, the high-voltage neutralizer of the general structure has the risk of spark discharge, so it cannot be used in a dangerous environment.

3. Radial neutralizer.

This type of neutralizer consists mainly of trace amounts of radioactive elements and a shielding frame. , the ray can ionize the air, therefore, the shielding frame opening is facing the charged body, and close to a certain distance can occur the power dissipation effect. Due to the radioactive contamination it may produce, there are not many applications.

Wrong.

The electrostatic neutralizer is also the electrostatic eliminator, which is mainly for the insulation material to remove static electricity, and the conductor is good for grounding treatment if it is in addition to static electricity, unless it is a petrochemical enterprise that needs special electrostatic grounding equipment, otherwise it is good to have static electricity on the general machine.

Static neutralizer is a static eliminator. The working principle of the static eliminator is: the high-voltage generator and the discharge electrode make a strong electric field between the discharge electrode and the grounding electrode, the air molecules are ionized, the discharge electrode tip alternately produces positive and negative ions, when the wind blows a large number of positive and negative ions to the surface of the object to neutralize the static electricity, or directly put the static eliminator close to the surface of the object and neutralize the static electricity.

Hazards of static electricity.

1. Static electricity affects the central nervous system: In winter, when the weather is relatively dry, people are prone to static electricity. However, the accumulation of excessive static electricity in the human body will cause abnormal electrical conduction in the brain nerve cell membrane, thus affecting the central nervous system.

2. Affect the physiological balance of the body: too much contact with static electricity in the human body will lead to changes in the pH of the human blood and the oxygen characteristics of the body, causing dizziness, headache, irritability, insomnia, loss of appetite, trance and other symptoms.

3. Affect the normal work of various organs (especially the heart): static electricity will interfere with the human blood circulation, immune and nervous system, and may cause abnormal heart rate and premature heart beat, thereby affecting the normal work of various organs (especially the heart).

According to the different working principles and structures, electrostatic neutralizers can be roughly divided into induction neutralizers, high-pressure neutralizers, radial neutralizers and ionic wind neutralizers.

1.What is an electrostatic neutralizer?

An electrostatic neutralizer, also known as an electrostatic eliminator, is a device used to eliminate an electrostatic charge. It reduces or eliminates the electrostatic charge on the surface of an object by releasing charges of opposite polarity.

2.How electrostatic neutralizers work.

Electrostatic neutralizers work by injecting an ionizer into the air, producing negative ions and cations, as well as generating an electric field. When ions flow through the surface of an object, they take away the electrostatic charge from the surface of the object, neutralizing the surface of the object.

3.What is the main purpose of an electrostatic neutralizer to eliminate?

Electrostatic neutralizers are mainly used to eliminate electrostatic charges. Electrostatic charges can arise in a variety of situations, for example, when a plastic bag falls off hair or clothing, when two objects rub against each other, an electrostatic charge can be created between them, causing them to stick to each other. Electrostatic charges can also be generated during industrial production and manufacturing, for example, when plastics or metals are cut or extruded, or when inks or chemicals are transported on conveyor belts.

4.Application of electrostatic neutralizers.

You're talking about static eliminators. It has two kinds: one is to use the high voltage (about 100,000 volts) generated by the coil to eliminate static electricity; The other is to eliminate static electricity by using the high voltage (about 60,000 volts) generated by charging and discharging capacitors.

Principle of static eliminator: In industrial production, there are charges of different properties on the surface area of objects due to friction, peeling, extrusion, induction, etc. between items. When this charge accumulation reaches a certain level, electrostatic adsorption and discharge occur.

There are several main types of static eliminators:

1. The AC corona product AC high voltage generator will raise the 220V input voltage to 7kV-10kV, the discharge electrode alternates between positive voltage and negative voltage at 50Hz frequency, a strong electric field is generated between the discharge electrode and the grounding electrode, the air molecules are ionized, and the discharge electrode tip alternately produces positive and negative ions. When the surface of the charged object is positive, the negative ions will be neutralized, and conversely, if the surface is negative, the positive ions will be neutralized. AC corona products must be grounded to work normally, but some positive and negative ions will be directed to the ground due to grounding, so the neutralization ability is slightly poor, but the structure is simple, the balance of positive and negative ions is good, and it is economical.

Second, the DC corona product DC high voltage generator will increase the 220V input voltage and output positive voltage and negative voltage respectively, a strong electric field is generated between the positive and negative discharge electrodes, air molecules are ionized, positive discharge electrode tip produces positive ions, negative discharge tip produces negative ions, positive and negative ions are generated at the same time to neutralize the static electricity on the surface of the object, when the surface of the charged object is positive potential, the negative ions will be neutralized, on the contrary, if the surface is negative potential, the positive ions will be neutralized. DC corona products can generate positive and negative ions without grounding, and the positive and negative ions acting on the surface of the object are sufficient, and the neutralization of static electricity is very fast. For example:
