摘要: 根据某地下石油库复杂洞室通风设计、通风优化的实际情况,结合以前洞室施工的经验,总结了提高通风效率的一些措施与认识。内容涉及到有效风流长度、风流路径、季节对通风的影响、通风风速、风管及其布置、风机布置诸方面,特别提到了计算机数值方法预先模拟通风效果的重要性,其不但可以预先评估通风方案设计,还可以在施工期间优化通风措施,结果涉及到流场分布、污染气体的排出过程,定量分析不同路径的排烟效果等诸方面。实践证明数值模拟方法是研究、解决通风问题的有效手段,对类似地下洞室施工的通风设计与布置有参考价值。

关键词: 通风效率, 复杂洞室施工, 通风设计, 优化通风措施

Abstract: The measures of improving ventilation efficiency are summarized in terms of effective length of air flow, air flow tracks, impacts of different seasons on ventilation, wind speed, and arrangements of air ducts and fans. The design and optimization of ventilation in a complex underground oil-storage cavern is taken as an example. The importance of numerical simulation is especially emphasized. It could assess and optimize ventilation schemes, calculate the distribution of flow field, and analyze the effects of different ventilation passages. Experiences showed that numerical simulation method is an effective method of solving ventilation problems.

Key words: ventilation efficiency, construction of complex cavern, ventilation design, optimization of ventilation
