大型直接空冷机组排汽管道均流等压优化设计研究

Study of Optimization Design of Equal Flow and Equal Pressure in Exhaust Pipe of Large Direct Air-cooling Unit

对直接空冷排汽管道中水蒸气在管道中流动导致水蒸气凝结为水,引起各分配管流场不均匀的现象进行了研究,通过采取延长导流板、移动导流片位置等措施,改善了各分配管中的流量和压降。

The problem that water vapor flows in the direct air-cooling exhaust pipe and part of the water vapor condenses into water,causing the uneven flow field in each distribution pipe,is studied.The flow rate and pressure drop in each distribution pipe are improved by optimization measures.
