Document Type and Number:
WIPO Patent Application WO/2008/038349
Kind Code:
A1
Abstract:
This invention provides a wet-type electric dust collector which has improved
corrosion resistance while properly ensuring discharge action. A layer is provided
on a discharge electrode in an electric dust collector for removing mist contained
in a corrosive exhaust gas. The layer is formed by coating the whole surface of
a needle-type rigid discharge electrode, provided with a support pipe and a discharge
needle, with a thermoplastic resin. The coating layer in the front end face of
the discharge needle is removed by rough polishing to expose a coarse discharge
end face.
