Abstract:
A method for cleaning a plurality of filter plates which are used to capture fly ash in an electro-filter built into a filter housing comprising:providing water under pressure in a pipe; providing a plurality of nozzles on the pipe in fluid communication with the pressurized water for issuing a jet of pressurized water therefrom; mounting the nozzles on opposite sides of the pipe in a plane which deviates slightly at an oblique angle from a plane of the plates; and displacing the pipe and nozzles to a given extent along the side edges of the filter plates while simultaneously rotating the nozzles such that the pressurized water is sprayed on the plates at an angle of incidence such that the furthermost areas on the sides of the plates are sprayed, thereby cleaning the plates.
