3工艺过程流程图

1第四章工艺流程设计郝红勋副教授化工设计★工艺流程是工艺设计的核心,它通过工艺流程图的形式，形象地反映化工生产由原料进入到产品输出的过程，其中包括物料和能量的变化，物料的流向以及生产中所经历的工艺过程和使用的设备仪表等。

★工艺流程图集中地概括了整个生产过程的全貌。

★控制仪表是工艺流程中重要组成部分。

2本章要求掌握PFD 图的基本内容和画法 掌握PID 图的基本内容和画法3工艺流程图：把各个生产单元按照一定的目的要求，有机地组合在一起，形成一个完整的生产工艺过程，并用图形描绘出来。

4工艺流程图分类：工艺流程框图（PBD）工艺物料流程图（PFD）带控制点的工艺流程图（工艺管道及仪表流程图-PID图）Piping and Instrumentation Diagram54.1 工艺流程框图（PBD图）工艺流程示意图也称工艺流程框图通常是用来向决策机构、高级管理部门提供该工艺过程的快速说明，如项目建议书、可行性研究报告中所提供的就是流程示意图。

工艺过程的总体概念用方框流程图按不同的部分表示，每个方框根据不同的详略要求，可以是整个工艺流程的一个部分，也可以是一个操作单元。

6流程示意图一般用细实线矩形框表示，流程线只画出主要物流，用粗实线表示，流程方向用箭头画在流程线上，并加上其他必要的注释等。

图4-17工艺物料流程图在物料衡算和热量衡算后绘制，简称PFD图(Process Flow Diagram)。

此图是以图形与表格相结合的形式来反映物料衡算结果它主要表示出该化工流程中主要设备的物料状态，如温度，压力，流率和组成等。

它可作为设计审查的资料，并作为进一步设计的重要依据，同时也作为日后生产操作的参考。

The pipeline open principle: the main pipeline connection, the principle of pipeline disconnected: main materials and auxiliary materials pipeline pipeline connection is disconnected; disconnect the horizontal or vertical line; disconnect pipeline, continuous control line; disconnect the horizontal or vertical line; the pipeline system, continuous meter connections disconnected etc.. Instrument wiring disconnection and so on. 3-14. The main valves and important fittings must be drawn in the material pipeline of PFD. PFDmaterial pipeline must draw the main valve and important pipe material, the pipeline must draw the main valve and important pipe fittings.If a graph can not fully represent the whole process, it can be drawn into multiple process flow charts when the whole process is not completely expressed when a graph can not fully represent the whole process. When the part is disconnected, the drawing process is drawn. In the figure, the inlet and outlet points of the material are represented by a sharp box with a sharp box. The inlet and outlet points of the material pipeline are represented by a sharp box, and the flow chart number and the equipment number of the material coming or going are explained.Flow chart number and equipment position number.
