摘要
在充分分析和研究现有设备及监控基本状况的基础上,首次将DCS技术引入萜类化学品中试设备的升级改造,研究、设计并构建起萜类化学品中试设备的中央数字化监控系统(简称CDMCS)。完成了CDMCS系统调试、设备调试、联机试运行和实际投料应用试验,实际成功运行时间90多天,达到了预期效果,温度控制精度为±1℃,显示精度为0.1℃,压力控制精度1 kPa,显示精度0.1 kPa。为我国林产化工行业及生物质化工行业进行产业技术水平提升和数字化控制技术应用创造了成功范例,取得了成功的经验,具有积极的示范作用和广阔的推广应用前景。
Based on analyzing the present monitoring and controlling situations of the pilot-plant equipments for terpene chemicals, DCS technique has been firstly conducted to design and construct the CDMCS （Central digital monitoring and controlling system）, and then applied to upgrading reconstruction for central monitoring system of terpene chemicals pilot-plant equipments. The CDMCS has passed system and equipment debygging, online operating tests, and application tests. The CDMCS has run in real charge operations for 90 days and it reached the predictive goal and effects ： temperature accuracy ± 1 ℃ for controlling, and 0.1 ℃ for displaying, pressure accuracy 1 kPa for controlling, and 0.1 kPa for displaying. The work is a new practice, and can play a good modeling role and have bright application prospect for reconstruction of old systems such as the terpene chemicals pilot-plant equipments in research organizations or industrial enterprises.
