| 摘 要： | 运用计算流体动力学(CFD)方法,对具有超压防护功能的某化学事故应急救援手术方舱室内气体污染物运动扩散的规律以及对人员安全的影响进行了数值模拟,其研究结果表明:当大气环境中氢氰酸(HCN)浓度为5mg/L时,前10s从常规进风口进入舱室的HCN在滤毒通风装置开启后,随气流运动逐渐向整个舱室扩散,经净化空气的混合稀释作用,绝大部分通过舱体缝隙排出舱室,30min内舱室HCN浓度的总量下降了95.1%,说明超压防护很好地保证了舱室环境的安全性。 |

| Abstract: | The numerical simulation based on computational fluid dynamics (CFD) is carried out to investigate the gas contaminant movement and distribution as well as influence on human safety inside compartment, which is for chemical accidents rescuing operation shelter with overpressure protection. Results indicate that HCN(hydrogen cyanide)entering from outside environment during first ten seconds diffuses to the whole compartment and goes out through crevice after filtering ventilation system working, the concentration of HCN reduces 95.1% during thirty minutes while it is 5 mg/L in atmosphere. It is proved that ventilation can satisfy the requirement of contaminant dilution and overpressure protection can keep compartment safety well. |
| Keywords: | overpressure protection filtering ventilation HCN(hydrogen cyanide) contaminant concentration compartment safety numerical simulation |
