The Electrostatic Precipitator

Introduction

In many Industries, some of the matter that is created must be cleaned and filtered. This is where the electrostatics precipitator comes in. This invention was build to filter a gas stream to clean it of anything unwanted like dust and dirt. It is used in many industries today. The precent of debris that is filtered out using this machine is 99%.

How it Works

It is a particle control device that uses electrostatics to move dust and other harmful toxins out of a gas stream.The precipitator works by making an negative charge on the bad particles, causing them to be attracted to the positively charged metal plates placed at the end of the precipitator. When enough dust has accumulated, the metal collectors are shaken to loose the dust, causing it to fall into hoppers below.

The Steps Involved

  • Ionization - The Charging of the particles
  • Migration - The Transporting the charged particles to the metal collecting surfaces
  • Collection - The falling of the charged particles onto the collecting surfaces
  • Charge Dissipation - The neutralization of the charged particles on the collecting surfaces
  • Particle Dislodging - The removal of the particles from the metal collecting surfaces to the hopper
  • Particle Removal - The conveying of the particles from the hopper to a disposal point
