专用设备真空干燥时间分析

Analysis of Vacuum Drying Time for Specialized Equipment

针对专用设备真空干燥耗时较长,严重影响专用设备启动运行进度,提出一种缩短专用设备真空干燥时间方法。首先对已完成的真空干燥数据进行分析,通过数据拟合与实测数据得出专用设备单台排液量与真空干燥时间方程。通过该拟合方程,在已知前几天排液量的情况下,可以计算出专用设备真空干燥结束时间。通过计算出的真空干燥时间,可以合理安排后续调试启动工作。其次结合抽空系统与现场实际情况,改进抽空线路,缩短专用设备真空干燥时间。A method is proposed to shorten the vacuum drying time of specialized equipment, which takes a long time and seriously affects the start-up and operation progress of specialized equipment. Firstly, analyze the completed vacuum drying data and obtain the equation between the drainage volume of a dedicated equipment and the vacuum drying time through data fitting and actual measurement data. By using this fitting equation, the end time of vacuum drying for specialized equipment can be calculated based on the known discharge volume in the previous few days. By calculating the vacuum drying time, subsequent debugging and start-up work can be arranged reasonably. Secondly, by combining the evacuation system with the actual situation on site, the vacuum drying time of specialized equipment can be shortened by improving the evacuation circuit.
