本实用新型涉及一种顺丁橡胶装置脱水塔防聚合系统,包括脱水塔和冷凝器,脱水塔通过塔顶气相线连接冷凝器,还包括阻聚剂配制罐,阻聚剂配制罐的阻聚剂出口通过阻聚剂输出管道连接塔顶气相线。本实用新型通过向塔顶气相线注入阻聚剂,可以有效防止顺丁橡胶装置中的丁二烯自聚,有利于装置长周期运行
The utility model relates to a dehydration tower anti-polymerization system of a butadiene rubber device, which comprises a dehydration tower and a condenser. The dehydration tower is connected with the condenser through the top gas phase line and also comprises a polymerization inhibitor preparation tank and a polymerization inhibitor inhibitor tank The outlet of the agent is connected to the overhead vapor line through a polymerization inhibitor outlet pipe. The utility model can effectively prevent butadiene self-polymerization in the butadiene rubber device by injecting a polymerization inhibitor into the gas phase of the tower top, which is favorable for long-period operation of the device
