压榨DCS在甘蔗糖厂生产过程的应用

The Application of Crushing DCS in Sugar Mill Process

针对甘蔗糖厂压榨生产过程的特点,介绍了压榨DCS的系统设计和系统功能实现。该自控系统已在翁源糖厂、平果糖厂、景真糖厂等多家糖厂应用。以翁源糖厂为例,系统使用后,压榨生产安全率达到99.9%,抽出率提高0.31百分点,转光度降低0.22百分点。压榨生产过程实现了均衡、安全、稳定、高抽出、低消耗的目的。

According to the characteristics of crushing process in sugar mill, this paper introduced the design of crushing DCS and realization of its system function. This automatic system had been used in Wengyuan Sugar Mill, Pingguo Sugar Mill, Jingzhen Sugar Mill etc. For example, after using the system, Wengyuan Sugar Mill had obtained a security rate of 99.9% in crushing process operation, an increase of 0.31 in sucrose extraction percentage, and a decrease of 0.22 in juice pol. The application of the system achieved the desired goals of equilibrium, safety, stability, high sucrose extraction and low energy consumption.
