深井水除砂是以地下水为水源的供水系统中的一个难题,尤其是直接与供水管网相连接的深井。天津市自来水公司带着这个问题,在实践中经过反复的试验,找出了沉砂的内在联系,并在兄弟单位的大力协助下,试制成功了“圆锥形旋流除砂器”。已经受一年多的实际考验。它的处理能力一般为40～65吨/小时,特殊情况下,可达100吨/小时,除砂效率达90% Deep-water de-sand removal is a problem in the water supply system where groundwater is the source of water, especially deep wells that are directly connected to the water supply network. The Tianjin Water Company took this problem and repeatedly tested it in practice to find out the internal connection of the sand. With the help of the fraternal unit, the trial successfully produced a “cone swirler”. It has been more than a year of practical trials. Its processing capacity is generally 40-65 tons / hour, under special circumstances, up to 100 tons / hour, sand removal efficiency of 90%
