Abstract
A high-voltage electrostatic precipitator is powered by a transformer supported below the high-voltage electrodes. A lead-in conductor extends from the transformer to the electrodes through a screen-covered aperture in the precipitator housing. Purging gas is directed through the aperture to prevent accumulation of particulates on the lead-in conductor.
Claims3
An electrostatic precipitator comprising a housing structure enclosing an array of elongate corona-generating electrodes, an upper end of each corona-generating electrode being attached to means for suspending said electrode within said housing structure, a lower end of each corona-generating electrode being attached to an electrically conductive means for applying electric power to said corona-generating electrodes, said electrically conductive means including a lead-in conductor extending outside said precipitator through an aperture in said housing structure to a step-up transformer, said transformer being supported at a level lower than said array of corona-generating electrodes, means for providing a flow of purging gas through said aperture into said housing structure during precipitator operation in order to inhibit accumulation of particulates on said lead-in conductor;
- and a screen member covering said aperture to prevent accumulation of particulates on said lead-in conductor.
