重庆市江北城江水源热泵三期取水工程工艺设计

Process Design of Chongqing Jiangbei Chengjiang Water Source Heat Pump Three-phase Water Intake Project

重庆市江北城CBD区域江水源热泵三期工程取水工程规模为17200m3/h,针对工程用地受限、场地内建构筑物复杂、嘉陵江水位和含沙量随季节变化以及三峡库区运行变动幅度大等问题,文中首创性采用“一级取水泵+二级过滤+二级加压泵”的闭式直流串联供水系统,通过多种合理优化设计,实现了节约用地、高效节能、与周边有机融合的目标。

The scale of the water intake phase III project for central cooling and heating project in Jiangbeicheng CBD area of Chongqing is 17200 m3/h. Several problems increase the difficulty of engineering design, including limited project land and complex Buildings and structures in the site. In addition, the water level and sand content of Jialing River vary greatly with seasonal variation and the operation of the Three Gorges Reservoir, also bring difficulties to technological design. The closed continuous flow water supply system of "primary water pump + two stage filtration + secondary water pump" is firstly applied in similar project. After reasonable optimization design, this project has achieved the goals of land conservation, high efficiency and energy conservation, and organic integration with the surrounding areas.
