卷烟燃吸模拟装置的设计与应用

Design and Application of Cigarette Smoking Simulator

设计了一种卷烟燃吸模拟装置,对其控温性能进行了评价,比较了烟丝在该装置中模拟燃吸时的裂解产物与卷烟采用吸烟机抽吸产生的烟气成分之间的差异,考察了采用该装置裂解烟丝所产生的NH3,HCN和苯酚的重复性。结果表明:①该装置具有较快的升温速率和较大的样品容量,当升温速率分别为50,100和150℃/s,未装载样品时,其实测温度曲线的相对标准偏差(RSD)分别为4.80%,5.10%和8.10%,装载样品时,RSD分别为3.50%,3.65%和9.02%;②该装置能够实现烟丝裂解产物的定量捕集,裂解产物经GC/MS分析,共鉴定出141种成分,比卷烟烟气成分多16种,其产生量也高于烟气成分的释放量;③该装置裂解烟丝样品的实验重复性较好,NH3,HCN和苯酚的RSD分别为2.54%,7.32%和3.11%。

A cigarette smoking simulator was designed, and its performance in temperature controlling was evaluated. The pyrolytic products of cut tobacco produced by the simulator was determined and compared with the smoke components of cigarette smoked by a smoking machine. The repeatabilities of NH3, HCN and phenol contents in the pyrolytic products of cut tobacco treated by the simulator were investigated. The results showed that： 1） The simulator featured faster heating rate and larger sample capacity. At the heating rates of 50, 100 and 150 ℃/s, the RSDs of measured temperature curve were 4.80%, 5.10%, and 8.10% without sample loading, and 3.50%, 3.65%, and 9.02% with sample loading, respectively. 2） The pyrolytic products could be trapped quantitively, 141 components were identified by GC/MS, 16 components more than that in cigarette smoke. And the yields of most pyrolytic products were higher than their counterparts in cigarette smoke. 3） The simulator featured good repeatability, and the RSDs of NH3, HCN and phenol were 2.54%, 7.32% and 3.11%, reslaectivelv.
