| 摘 要： | PH3和CO2 混合熏蒸及微气流熏蒸试验在砖结构的立筒仓中进行。试验表明 ,微气流熏蒸时PH3保持有效浓度的时间远远长于混合熏蒸。混合熏蒸PH3易渗漏的原因之一是仓内气体压力较高。本文还对混合熏蒸药剂的渗透力及立筒库熏蒸方法的选择进行了讨论

| Abstract: | The test of PH 3 and CO 2 mixed fumigation and micro-airflow fumigation in brick silo were carried out.The results showed that with micro-airflow fumigation,the maintenance time of PH 3 effective concentration was far longer than that of mixed fumigation.PH 3 easy to leak during mixed fumigation was due to high pressure in silo.PH 3 and CO 2 permeability in mixed fumigation and choosing appropriate fumigation method for silo were also discussed. |
