阻聚剂的物理化学特性,通过理论汁算和对文际工况的分析,给出设计的基本参数,指导设备加工和制造,
再通过现场测试,找出最优的操作参数。试结果表明:采用氮气輸送顆粒状阻聚剂,可以避免固体破碎
后产生的粉尘爆炸危险,并且送量可达到200kg/h的低流量输送目的。固气比控制在3.3,不阻寒管

Abstract:; Pneumatic conveying le nology is applied in inhibitor pre aration system of butyl acrylate plant and successfully solves
the traditional preparation process bottlenecks, with advantages of more safety, less pollution, more reliable and higher automation, Fo-
cusing on the process design and combining with the physical and chemical propeties of butyl acr late and inhibitor, the databases
which guide for equipment manufacturing are worked out through theoretical calculations and the actual working eonditions analysis. The
optimization parameters are ohtained through the site test The results show that using nitrgen to corvey granulate inhibitor, the cove
ying capacity can reach up to 200 kg/h without the risk of dust explosion, and when the solid-gas mass ratio is controlled in 3.3, it can
meet the requirements of pneuma ie conveying without locking, and the stiming speed is at 35 /. The solid pa icles are preferably
