摘要
在酒精室外蒸馏设备操作中,液位控制技术非常重要,若液位控制不稳,将严重影响设备生产能力。采用自控仪表控制法控制液位,即在回流罐、差压塔的塔釜各安装一套液位自动控制系统,采取回流罐或塔釜液位变化为信号,自动调节阀门的开关程度。该法虽投资较大,但使用效果很好,能及时同步调节,性能稳定可靠,适应于各种液位控制。
Liquid level control was the key operation in alcohol outdoor distillation. Inadequate liquid level control would seriously influence the production capacity. Self-controlled instrument system, by installing a set of liquid level automatic control system on tower kettle of reflux pot and differential pressure tower which could adjust automatically the switch of threshold according to liquid level changes of reflux pot or of tower kettle, had satisfactory effects, though such system was in need of large investment, it could realize synchronous adjustment timely and it had stable and reliable performance suitable for the control of various liquid level.
