Patent ID: 8454733

Claim:
An air handling device having an air flow path in which a charge section for charging dust in an air to be handled, and a precipitator for collecting the charged dust are placed, wherein the charge section includes a discharge electrode and a counter electrode to perform diffusion charging, a diffusion space is provided at a location between the charge section and the precipitator, a first charge section adopting an impact charging technique is positioned on an upstream side of a direction of the air to be handled, and a second charge section adopting a diffusion charging technique is positioned on a downstream side of the direction of the air to be handled, a discharge electrode of the first charge section and a discharge electrode of the second charge section are constituted by an integral discharge electrode, and a counter electrode of the first charge section is located on the air flow upstream side, and a counter electrode of the second charge section is located on the air flow downstream side, relative to the discharge electrode.
