蒸汽动力船舶疏水系统设计

摘要

The reasonable design of the draining system of ships is of paramount importance to improve the cost-efficiency and operation safety of equipments. As few paper discusses the design of the ship's draining system, a method to calculate the drained water volume and the drained water direction is presented on the basis of blow-off operating condition analysis. The thermal steam trap that applies to the blow-off operating condition of the steam system is selected through the comparison of many steam traps. Finally, the practical-ity, efficiency, and rationality of the proposed design method are validated.%蒸汽动力船舶疏水系统的合理设计对提高热力系统的经济性以及保证设备的安全运行至关重要,针对鲜有文献对其设计进行论述的现状,从疏水系统设计需求出发,在蒸汽系统吹除工况分析的基础上,提出蒸汽系统疏水量的计算方法和系统凝水去向设计原则.通过对多种疏水器性能进行比较,得出热动力疏水器适用于蒸汽系统吹除工况.在对某型船舶疏水系统问题总结的基础上,提出了疏水系统的布置方案.通过较好实现某型船舶疏水系统功能,验证了该疏水系统设计方法的合理性.
