【Abstract】 To counter the problems in discharge of sludge from settlers, a new type perforated pipe with divergent tube is developed. Based on the principle of hydraulics, the divergent tube is high in discharge coefficient and velocity coefficient at the inlet and high in vacuum at the contraction section, so the efficiency of sludge discharge increases significantly. It offered also such advantages as reliable and easy operation, lower cost, etc., and can be used in the new construction and rebuild of sludge removal system of settlers.更多还原
