| 摘 要： | 为了避免在石灰乳的制备过程中石灰乳液夹带的不溶性杂质对整个系统危害,通过对石灰乳制备工艺的分析以及石灰渣分离装置的比较,得出利用旋流除渣器对石灰渣进行分离是比较适用的方法。旋流除渣器在中国石化巴陵石化公司8000 t/a环氧丙烷装置的应用结果表明,旋流除渣器的平均分离效率大于80%,石灰渣的平均脱除率达到了81.35%,皂化塔清洗周期延长到40～50天,实现了整套装置长周期稳定运转,降低了设备损坏率,减少了环境污染。

| Abstract: | In order to avoid the harm of the undissolved impurities to the entire system in the process of the lime-milk’s preparation,the preparation technology of lime-milk and the separation equipment of slag are analyzed.It indicates that hydrocyclone is more applicable in the separation of slag.Hydrocyclone scummer device was found in 8000 t/a epoxy propane unit of Baling Petrochemical Company.The average separation efficiency of hydrocyclone scummer device was above 80%,the average removal rate of slag reached 81.35%,and the cleaning period of saponificationcolumn was prolonged to 40—50 days.It has realized the long period stable operation for the whole device,and reduced the damage rate and the environmental pollution. |
