HORIZONTAL SCREW DECANTER APPLIED THE FORCE OF AN INDUCED ELECTROSTATIC CHARGE IN SLUDGE FEED PIPE LINE

摘要

DC (direct current) electricity is applied to a sludge influx part by one horizontal centrifuge separator, is arranged to reduce water content by removing the pure solid material separated with moisture, the core of the microorganism of sludge is stayed in, by applying electricity during preliminary step. In the horizontal centrifuge separator that DC electricity is applied to a sludge influx part, a metallic conductor is installed in the feed pipe in the sludge influx part form in a screw shaft. One application of electrode+electricity.-- electricity is applied to a feed tube body connecting flange. A metal conductor support is by an insulation method treats and assembles. One electric forming of application circuit in a transformer lower than 300V+and -- contact point unit, respectively easily control electric power the profit and loss. DC electricity is applied to influx sludge and the sludge mixed with a polymer coagulant to handle sludge.
