The problems in the design of smoke prevention compartmentalization,air current speed,tube discharge of smoke in each compartmentalized zone,and natural air replenishment were discussed through the introduction and analysis of the designing principles,criteria,and the operational mode on the occasion of fire.
通过对地铁防排烟设计原则、设计标准、火灾工况下防排烟系统运行模式等方面的分析和介绍,对地铁车站在防烟分区划分、气流流速、区间隧道排烟、自然补风设计方面存在的问题进行了探讨。
Investigation on optimized gas recovery velocity of natural gas storage in salt rock layer by numerical simulation;
盐岩储气库最佳采气速率数值模拟研究
Compared with the MSW landfill alone, the landfill gas generation rate of MSW co-disposed with sludge was higher by about 30%.
实验结果表明 :在填埋垃圾中添加污泥起到了接种微生物的作用 ,加快了有机垃圾的降解与填埋气的产生 ,产气速率较生活垃圾直接填埋提高3 0 %以上 ;填埋气中CH4 浓度可达到 64% ;与没有添加污泥相比 ,填埋气中CH4 含量有较大幅度的提高 ,有利于填埋气的资源化利用 ,同时也可为污泥的资源化利用提供经济可行的途
Based on research and production of foaming agent ADC,the activating agent selection and the influence of activating agent on the decomposition temperature,the gas forming rate and the gas forming amount of foaming agent ADC are related emphatically.
从低温发泡剂的研制入手,重点阐述活化剂的选择和活化剂对发泡剂ADC的分解温度、发气速率及发气量的影响,研制出的产品分解温度低,泡孔洁白细腻,具有更广泛的适用性。
