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。
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.
