The diagram is of Electrostatic precipitator.



An electrostatic precipitator is one of the many ways of removing particulate matter from the exhaust of thermal plants. It is efficient in removing up to 99% of particulate matter. It consists of electrode wires, maintained at several thousand volts, which discharges corona which in turn releases electrons. These electrons get attached dust particles resulting in negatively charged particles. These charged particles get collected in collecting plates.
