针对沉淀池排泥过程中所存在的问题，研制了一种新型的排泥装置——扩张管嘴排泥管。该装置利用水力学中扩张管嘴进口流量系数大、流速系数高、收缩断面处真空度高的原理，使其排泥效率显著提高。另外，该装置还具有运行可靠，造价低，操作方便等优点，可广泛用于沉淀池排泥系统的新建和改造。
針對沉澱池排泥過程中所存在的問題，研製瞭一種新型的排泥裝置——擴張管嘴排泥管。該裝置利用水力學中擴張管嘴進口流量繫數大、流速繫數高、收縮斷麵處真空度高的原理，使其排泥效率顯著提高。另外，該裝置還具有運行可靠，造價低，操作方便等優點，可廣汎用于沉澱池排泥繫統的新建和改造。

To counter the problems in discharge of sludge from settlers,anew 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.
