淮阴输卤泵站扩产与节能改造的研究

Study on the Capacity Expansion and Energy Saving Modifications of Brine Transportation Pump Station at Huaiyin

对淮阴至连云港输卤管线进行了调查研究,在首站多台泵并联运行试验的基础上,指出只有设置中间泵站才能提高外输量。经阻力计算,提出外输量600×104m3/a的管线改造以及中间泵站设计的最优方案,同时明确了该管线最大输卤能力;另对输送工艺的优缺点分析比较后,认为卤水输送采用密闭输送的方式更经济合理。

Through investigation and study on the brine pipingline from Huaiyin to Lianyungang and on the basis of testing the running of several pumps in parallel connection in the first station, this paper points out that transportation capacity can be increased only when intermediate pump station is set up. The resistance calculation suggests that the modification on the pipingline with transportation capacity of 600×10^4m^3/a and the design of intermediate pump station are an optimal choice, and in the meantime the maximum brine transportation capacity is fixed. In addition, a closed-circuit brine transportation system is more economic and rational based on the analysis on the pros and cons of the transportation process.
