Production method of electrostatic precipitator, discharge electrode and discharge electrode, and production method of discharge needle

摘要

While guaranteeing discharge action precisely, it improves corrosion-resistant in the wet electrostatic precipitator. The whole surface of the needle equipped type rigid body discharge electrode which possesses the support pipe and the discharge needle vis-a-vis the discharge electrode of the electrostatic precipitator which removes the mist in the waste gas which has corrosiveness, the layer which coating is done is provided with the thermoplastic resin. And, grinding the coating layer of the advanced aspect of the aforementioned discharge needle roughly, removing, the eye it made the discharge end face expose roughly.
