1, gas ionization

Gas is generally neutral, but when the gas molecules to obtain a certain energy, it will be separated into electrons, positive ions, negative ions, so that the gas into a conductive body. The process of making a gas having a conductive property is called a gas. The ionization of gas is divided into spontaneous and non spontaneous. Non spontaneous ionization of gas is generated under the action of an ionizing agent (such as flame, ultraviolet rays, X rays, etc.); the spontaneous ionization of gas is generated under the action of a high voltage electric field.

When the electric field is about cm / lOkW, the gas can generate electricity from the electrons and ions, but the voltage between the two poles is too high, and the electrode can produce intense sparks. Because of the difficulty of maintaining the corona discharge in the uniform electric field, the air is easy to be attacked by the two poles.

2, electrostatic dust removal principle

The dust gas is formed by the high voltage DC power supply. The power supply is a non uniform electric field, which is formed by the high voltage DC power supply. The negative electrode is called the cathode, the anode and the cathode. Because of the corona pole distance short cations near the corona pole in trend, low speed, touch the dust on the few opportunities, therefore, most dust and long distance of negative ions collided and negatively charged, flying dust collecting electrode, only a handful of dust deposition in corona gyok, periodic vibration play set dust Noni and corona pole, two stage adsorption of dust fall into the dust retainer and ash unloading device of unloading to the conveying machinery transported through the.
