Study on effect of spillway trough on deposition efficiency of intermittent scouring sand basins;
溢流槽对定期冲洗式沉沙池沉淀效率的影响分析研究
Traditional sediment tank has been improved in three aspects by putting an adjusting flow wall in the entrance of water, a spillway trough on spillway crest along the flow direction, redesigning the flush device and an auxiliary fl ush facility.
通过在沉砂池的进水处加调流墙、在溢流堰上沿水流方向设溢流槽、对排砂装置进行改进以及设置辅助冲砂设施三个方面对传统平流式沉砂池进行了改进,设计提出了一种新型平流式沉砂池,可以大大提高沉砂池的沉淀效率,特别是对细颗粒泥砂的沉淀具有很好的效果。
, setting an adjusting flow board in the fore of setting basin, adding a spillway trough along the flow direction, and redesigning the flush gallery by adding auxiliary flushing facilities.
在对各种类型沉沙池及适用条件进行分析的基础上,通过在沉沙池的首部加调流板、在溢流堰上沿水流方向设溢流槽、对冲沙廊道进行改进并设置辅助冲沙设施这3个方面对传统沉沙池进行了改进。
