摘　　要：以实际项目为例,通过对项目可燃物质的分析,管壳式换热器工艺泄漏量的计算,以及如何考虑泄漏的可燃物质对冷却塔的影响,对冷却水塔是否需要进行防爆设计进行分析说明,从而避免在设计过程中过于保守,在保证本质安全的前提下避免过度设计,提高冷却水塔设计的合理性,最大化地节省设计及制造成本。Taking the actual project as an example,through the analysis of the combustible material,the leakage calculation for shell and tube heat exchanger,and how to judge the impact of leaked combustible material on the cooling tower,the paper describes whether it is necessary to carry out explosion-proof design for cooling tower,so as to avoid being too conservative in the design process,to avoid excessive design on the premise of intrinsic safety design,to improve the design rationality,and to minimize design and manufacturing costs.

关 键 词：冷却水塔 换热管破裂 爆炸下限
