摘要:

推导了通风系统净化系数与泄漏率及过滤器净化系数的关系,认为核通风系统存在微小的泄漏会导致系统的净化能力大为降低。以某核电厂为例,分析了通风系统泄漏的原因,并提出了降低泄漏率的措施。

Abstract:

Deduces the relationship between the purification coefficient of the ventilation system and the leakage rate and the purification coefficient of the filter material. Considers that small leakage of nuclear ventilation system will greatly reduce the purification capacity of the system. Taking a nuclear power plant as an example, analyses the leakage causes of the ventilation system and puts forward some measures to reduce the leakage rate.

Keywords:ventilationsystem,nuclearpowerplant,leakagerate,purificationcoefficient,highefficiencyparticulateairfilter
