- 摘要:
- 有毒气体泄漏时，疏散和就地避难都是保护人员安全的有效行动。当疏散行动无效时，此时可考虑进行就地避难，应急决策者必须准确认识就地避难的可靠性。文中模拟分析了渗透吸附作用、换气次数、避难室空间体积、有效吸附面积对避难室内浓度的影响。结果表明，渗透吸附作用的存在明显降低了室内浓度，且强度越大浓度越低；换气次数越小，浓度越低；避难室空间越大，浓度越低，但影响不明显；吸附面积与空间体积之比越大，浓度下降越明显；毒负荷指数越大，规定暴露时间内避难室内毒负荷上升越缓慢。最后确定了特定场景下避难室最佳换气次数
- Abstract:
- Evacuation and shelterinplace has usually been used to protect public from toxic gas release incidents. When evacuation is noneffective, shelterinplace should be considered. So emergency decisionmakers should have an accurate understanding on the reliability of shelterinplace. Effects of sink adsorption, air exchange rate, saferoom volume and effective adsorption area on saferoom concentration were studied in this paper. It showed that the existence of adsorption significantly reduced the indoor concentration, and the greater the intensity was, the lower concentration was; the smaller the air exchange rate was, the lower concentration was; the larger the saferoom volume was, the lower concentration was, but the effect was not obvious; the larger the absorption area and space volume ratio were, the concentration declined more obvious; the greater the toxic load index was, the lower toxic load increased in shelterinplace in stated exposure time. Finally, the optimal air exchange rate was determined in a specific scenario. This study will be helpful for guiding the selection and design of emergency shelters.
