孟加拉某电厂取水工程设计探讨
|
摘要
孟加拉某电厂取水工程取水河段河漫滩坡缓水浅且河水中泥沙含量较大,对取水工程的设计有较大的影响。通过比较采用了引水明渠、过渡前池及引水管等组合取水构筑物方案,该设计方案不但阻拦了部分泥沙进入取水泵房,还具有取水效率高、取水水质好,运行维护简单、灵活等特点,为今后浅滩淤泥质取水工程提供参考。
The floodplain slope of a power plant intake project in Bangladesh is shallow and the sediment content in the river is large, which has a great influence on the design of the intake project. y comparing and adopting the combined water intake structure scheme of diversion open channel, transition forebay and diversion pipe, the design scheme not only prevents some sediment from entering the intake pump house, but also has the characteristics of high water intake efficiency, good water quality, simple operation and maintenance, and flexibility, which can provide reference for the future silty water intake project of shallow beach.
