What are the main sections of a typical oil mist electrostatic precipitator from inlet to outlet?

The main sections of a typical oil mist electrostatic precipitator are designed to effectively capture and remove oil mist particles from the air stream, and the correct answer reflects the proper sequence of components involved in this process.

The first component, the baffle, serves to spread out the incoming air and to facilitate the removal of larger particles from the air stream through sedimentation or gravitational settling. This initial step is crucial as it helps reduce the load on subsequent components.

Next is the ionizer, which produces charged ions that attach to the oil mist particles in the air stream. This charging process is key to the operation of an electrostatic precipitator, as it enables the particles to acquire a positive or negative charge, allowing them to be moved towards the collecting electrodes by the electric field created within the precipitator.

Following the ionization, the collecting section captures those charged particles. It typically consists of plates that are oppositely charged to attract and hold the oily particles, thus removing them from the airstream.

Finally, the fan plays a role in moving the air through the entire system, ensuring that air continues to flow from the inlet to the outlet, while also providing the necessary air movement for the entire process to take place.
