ABSTRACT:
A method and apparatus for the control of the precoating process employed in an effluent filtration baghouse are described. An electrically operated pressure switch is provided to indicate the precoat duct vacuum pressure by measuring the vacuum pressure of the clean side of the baghouse. Should a precoat duct pressure insufficient to sustain the flow of precoat material be indicated, the pressure switch will halt the feed of precoat material into the precoat duct, thus avoiding the congestion of the precoat duct by the precoat material and the consequent inadequate precoating of the baghouse bags.
