Electrostatic precipitators (ESP's) are used to extract airborne wood dust particles from the air in the wood products workplace environment. Dust particles are charged by electrodes and adhere to the collector plates in the electrostatic precipitator. Inlet and outlet distribution plates ensure even distribution of flue gas over the collector plates. Electro-mechanical rappers dislodge the dust particulate from the electrodes and collector plates (rappers are located external to the electrostatic precipitator). The dust particles fall into a common hopper where they are exited through an air lock to the residual collecting conveyor system. The clean air is evacuated from the electrostatic precipitator into the atmosphere.
