Compared with other dust removal equipments, electrostatic precipitators consume less energy and have high dust removal efficiency. They are suitable for removing dust of 0.01-50 μm in flue gas, and can be used in places with high flue gas temperature and high pressure. Practice has shown that the greater the amount of flue gas treated, the more economical the investment and operating costs of using an electrostatic precipitator.

What is the reason why the electrostatic precipitator electric field often trips?

Do the airlift test and make sure there is no problem with the electronic control. However, there is no problem with electronic control. If there is, focus on the sampling board and circuit, relay.

Inside the electric field:

1, broken lines are more common;

2. The insulator is ashed;

3, the ash bridge bridges, blocked;

4, the reserved space for the plate chute is not enough; (this is well recognized, the exhaust gas temperature is high, the dust collector is air-lifted, and it starts to jump after 10 minutes of operation);

5. I have also seen that the cathode rapping insulation chamber produced by a small factory is covered with ash short circuit;

6. The dust collector is seriously leaking.

The positive electrode of the electrostatic precipitator is made of metal plates of different geometric shapes, called dust collecting electrodes. 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. The power supply of the electrostatic precipitator consists of a control box, a step-up transformer and a rectifier. The voltage level of the power supply also has a great influence on the dust removal efficiency. Therefore, the operating voltage of the electrostatic precipitator needs to be maintained at 40 to 75 kV or even 100 kV or more.

The working principle of the electrostatic precipitator is to use a 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.
