介绍亚硫酸法糖厂蔗汁中和p H值双回路智能控制系统的技术改造以及运行实践。运行表明,采用该项技术后,在制炼控制效果上实现质的转变,为糖厂带来显著的经济效益,同时还减轻了操作工人的劳动强度,对提高出糖率及产品质量、提高糖厂的自动化生产水平、降低生产成本效果良好,经济和社会效益显著。 This article introduces the technological transformation and operation practice of double circuit intelligent control system of bisulfite neutralization and p H value in sulfite sugar factory. The operation shows that after the adoption of the technology, the qualitative change in the refining control effect has brought significant economic benefits to the sugar mills while also reducing the labor intensity of the operating workers and improving the output of sugar and the quality of products The automated production level of sugar factories, reducing production costs and good results, significant economic and social benefits.
