Discharge electrode assembly for electrostatic precipitators

摘要

An improved high-voltage discharge electrode assembly for an electrostatic precipitator is disclosed. The discharge electrode assembly comprises, in combination, an elongated discharge electrode, an anchoring element, one end of the elongated discharge electrode being secured at the anchoring element, and a flexible shroud closely surrounding the elongated discharge electrode adjacent the anchoring element whereby the life of the electrode in the electrostatic precipitator is extended. In a preferred form, the flexible shroud is a closely coiled, cylindrical helical spring.
