Collection of parallel plate is one of electrostatic precipitator parts. The parallel plates serve as dust collector. These plates will be given high contrary voltage. Supporting plates of electrostatic precipitator are as follow:
- Support Insulator
Support insulator serves as a holder of positive and negative plates in electrostatic precipitator unit as shown in Figure 1 below.
|Figure 1: Support Insulator Discharge Electrode|
Another function of support insulator is as medium barrier (insulator) between frame (body) of precipitator and negative plate. Support insulator is equipped with heater and thermostat. The purpose of heater is to make temperature of insulator stable. If the temperature change over the insulator will be broken or damaged, so temperature must be maintained constant.
- Collector Plates
Collector plates as shown in Figure 2 is place of dust particle attach on it when it is given positive voltage source. Size of dust particles attached on collector plates ranged from 0.3 to 40 microns. Dust on collator plates are periodically removed through vibration (rapping) into dust hopper.
