Electric tar catcher

Electric tar catcher, also known as electric tar dust collector, electric light oil catcher, electric dust collector, electrical filter, etc. The commonly used structural forms of electric tar precipitators include concentric circle, tube, honeycomb, and so on. The design structures of these three types of electric tar precipitators are composed of various components such as the shell, sedimentation electrode, corona electrode, upper and lower hangers, gas redistribution plate, steam blowing tube, insulation box, and feeding box. The main differences in this single structure are the form of sedimentation electrode, the arrangement of corona electrode, insulation box, and feeding box.

Electric tar catcher is a device that separates tar droplets and coke oven gas under the action of high-voltage electrostatic field force. The use of electric tar precipitators can greatly improve product recovery rates and practical effects, mainly in the operating environment.

The three commonly used electric tar catchers in the current market are concentric circle electric tar catchers, tubular electric tar catchers, and honeycomb electric tar catchers. The main differences between these three structures of electric tar catchers are their sedimentation electrode form, corona electrode arrangement, and electrical insulation box.

Factors affecting electric tar precipitators:

1、 Excessive smoke flow

Due to the high gas flow rate in the flue gas, tar particles have not reached the wall tube, so the electric tar catcher cannot remove tar, which will affect the efficiency of the electric tar catcher.

2、 The flue gas temperature is too high

If the temperature of the processed flue gas is relatively high, the velocity of the airflow will be very high, thereby reducing the efficiency of the electrostatic tar precipitator.

3、 The power supply voltage is too low

If the voltage of the DC power supply is relatively low, it will produce mild and low corona, resulting in a decrease in the oil removal efficiency of the electrostatic tar precipitator.

4、 Excessive moisture in the smoke

If the humidity of the processed flue gas is relatively high, it will cause electrical discharge, thereby affecting the use of the electrostatic tar precipitator.

5、 Uneven gas separation in flue gas

If the gas separation of the flue gas is uneven, it will cause excessive local flow velocity, thereby affecting its oil removal efficiency.
