In this animation, we'll walk through the basic operating principle of an electrostatic precipitator, or ESP, focusing on how high voltage enables dust removal. Let's get started. In an electrostatic precipitator, dust particles are removed from the gas stream using electrostatic force, also called electric field force. A high voltage is applied to the spray electrode. This high voltage creates a corona discharge at the tip of the electrode. The corona discharge releases free electrons, which ionize surrounding gas molecules. As dust particles pass through the ionized gas, they receive an electric charge. The charged particles are deflected by the electric field and migrate toward the collection electrode. In an electrostatic precipitator, dust particles in the gas stream are charged by gas ions, deflected by the electric field toward the collection electrode, and collected there as a layer of dust. In summary, dust particles are charged, guided by the electric field, and collected on the electrode, completing the separation process.
