Improvement of the design of electromagnetic plunger for nanoparticles electrostatic precipitator (ESP) / Ahmad Faiq Abdul Hamid

One of the problems with nanoparticles using electrostatic precipitator technique is that they tend to adhere to the electrodes (plates). Work in the past made use of electromagnetic plunger to knock off the particles from the plate. However the collection efficiency was poor. This work focuses on a new method of removing the particles from the plate. A plunger made to be in concentric with coil can be made to move reciprocating. A brush is attached to the plunger so it can scratch away the particles left on the plates. With higher no. of turns, the forces can be made greater (1000 turns to 1500 turns). Two different types of plunger have been uses in this experiment such as copper and iron. The results are discussed based on the voltage supplied to the solenoid, different types of plates and times repetition of moving plunger in order to get the nanoparticles size in electrostatic precipitator process (ESP). The results showed that the proposed technique can be considered as one of the method to obtain nanoparticles.
