We have already known different types of dust collectors, and we will introduce another special dust collector, electrostatic dusting paper. Let us learn what electrostatic dusting paper is and what is his working principle?
working principle:
1. The working principle of the electrostatic precipitator is to use the high-voltage electric field to ionize the flue gas, and the dust charge in the gas stream is separated from the gas flow by the electric field. The negative electrode is made of a metal wire of different cross-sectional shape, called a discharge electrode. The positive electrode is made of a metal plate of different geometric shapes, called a dust collecting electrode. The performance of electrostatic precipitators is affected by three factors: dust properties, equipment construction and flue gas flow rate. The specific resistance of dust is an indicator for evaluating conductivity, which has a direct impact on dust removal efficiency. The specific resistance is too low, and it is difficult for the dust particles to remain on the dust collecting electrode, causing it to return to the airflow. If the specific resistance is too high, the dust particles reaching the dust collecting electrode are not easily released, and a voltage gradient is formed between the dust layers to cause local breakdown and discharge. These conditions will cause the dust removal efficiency to drop.
2. Electrostatic dust-removing paper can be used with electrostatic dust-removing mops, using static electricity to generate static electricity, adsorbing dust and hair on the surface. It can also be used alone. It can be used as a wipe to achieve the same effect. The computer can be removed, and the TV screen can be easily removed without worrying about scratching the surface.
3. The power will be settled by charged dust collection, which has high efficiency. Low energy consumption. In addition, plate electrostatic precipitators and charged water mist precipitators are commonly used in the industry, although the principles are slightly different.
4. Due to radiation friction and other reasons, the air contains a small amount of free ions. It is impossible to fully charge the dust particles in the dusty air by these free ions alone. Therefore, the use of static electricity to separate dust must have two basic conditions, one is that there is an electric field that charges the dust; the other is that there is an electric field that separates the charged dust particles. The general electrostatic precipitator adopts a method of charging electric field and separating electric occasion. The metal rod of the discharge electrode is connected to the negative pole of the high voltage direct current power source, the dust collecting pole is grounded to the positive pole, and the dust collecting pole can be a round tube or a flat plate.
