蒸氨系统的技术改造和生产管理

Technical modification and production management on ammonia stripping system

介绍了蒸氨系统生产现状,针对现行工艺存在塔阻、焦油、碱液浓度波动大以及氨水分缩器温度无法自动控制等问题,通过采取拆除进料层塔板泡罩,加高剩余氨水槽的抽出管道,加碱混合器由螺旋式改为隔板式,增加加碱备用管道,实现温度自动控制等措施,取得了良好效果。

The production present situation of ammonia stripping system is introduced, against the problems existed in the existing process such as big fluctuation of column resistance, tar content and soda lye concentration as well as no way for automatic control of ammonia liquor deflegmator, by means of the measures of dismantling feed column plate, increase the height of outlet pipe of coal water tank, changing the soda adding mixer from the spiral type into the partition plate type, increasing soda standby pipe, realizing temperature automatic control, the good effect has been achieved.
