Electrostatic precipitators

Working principle of electrostatic precipitator
Using high-voltage electric field to ionize the flue gas, the charged dust in the air flow is separated from the air flow under the action of the electric field. The negative electrode is made of metal wires with different cross-section shapes, called discharge electrodes. The positive electrode is made of metal plates of different geometric shapes, called dust collecting electrodes. The performance of the electrostatic precipitator is affected by three factors: dust properties, equipment structure 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. 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 voltage gradient formed between the dust layers will cause local breakdown and discharge phenomena. These situations will cause dust removal efficiency to decrease.
Performance characteristics
① Low energy consumption, high dust removal efficiency
② Suitable for removing dust in flue gas
③ And can be used in occasions with high flue gas temperature and high pressure
/>The greater the amount of flue gas treated, the more economical the investment and operating costs of using an electrostatic precipitator are.
