Explain the working principle of electrostatic precipitator





The performance of the electrostatic precipitator is affected by three factors: the nature of the dust, the structure of the equipment and the flow rate of the flue gas. The working principle of electrostatic precipitator is to use high-voltage electric field to ionize the flue gas, and the dust in the airflow is separated from the airflow under the action of the electric field. The negative electrode is made of metal wires with different cross-sectional shapes, called discharge electrodes. The positive electrode is made of metal plates with different geometric shapes, called dust collecting electrodes. The specific resistance of dust is an index for evaluating conductivity, and it has a direct impact on the efficiency of dust removal. If the specific resistance is too low, it is difficult for dust particles to remain on the dust collecting electrode, causing them to return to the airflow. If the specific resistance is too high, the charge of the dust particles reaching the dust collecting electrode will not be easily released, and the formation of a voltage gradient between the dust layers will cause local breakdown and discharge. These conditions will cause the reduction of dust removal efficiency. Let's see how to eliminate static electricity?
1. Instruments to eliminate static electricity:
In addition to static ion fans and electrostatic dust removal guns, ion fans can provide a wide range of static elimination areas, fast static elimination time and stable ion balance voltage in various working environments (including clean rooms).
2. Use anti-static products in the working environment: In the working environment, the floor adopts anti-static floor, auxiliary anti-static table mat on the surface of the work table, anti-static soldering station, anti-static IC pull-out station, and anti-static tin suction device during work. , And other auxiliary supplies (anti-static alcohol bottle, anti-static tweezers, standard with a bottle of static eliminator) 3. Wear (wear) anti-static products: wear (wear) anti-static gloves, anti-static wrist strap (connect to the ground Line), anti-static work clothes (a set or a single coat), anti-static work shoes.
