环流熏蒸在各个收储企业应用越来越广泛。一般都利用仓外发生器加CO2和仓内发生器加湿沙自然潮解、PVC探管投药以及粮面投药等。这些方法都存在不足,一是成本高、二是劳动强度大、三是易污染等。AlP在进风口集中投药是利用环流熏蒸风机在运行中产生的微风气流将AlP与空气中水分反应产生的PH3带入粮堆中,维持PH3有效浓度到一定时间。我库选择了7#仓在进风口投药环流熏蒸试验。1试验材料
Circulation fumigation in each storage enterprise application more widely. Generally use the warehouse generator plus CO2 and warehouse humidifier sand natural deliquescence, PVC probe dosing and noodles dosing. These methods are inadequate, one high cost, the second is labor-intensive, the third is easy to pollution and so on. Concentration of AlP in the air inlet is the use of the breeze airflow generated by the circulation fumigating fan to bring PH3 produced by the reaction of AlP and air moisture into the grain piles and maintain the effective concentration of PH3 for a certain period of time. I warehouse selected 7 # warehouse inlet air fumigation test. 1 test material
