年产20000吨三氯化磷生产工艺设计.pdf

摘 要 本文重点对三氯化磷生产进行了介绍，此外就其原理，工艺和方法这三个方面展开了全面的比 较。此举不仅对今后三氯化磷生产的研究有重要的参考意义，而且对其今后投入生产也打下了一定 的基础，在设计工艺流程 过程中，对多种工艺进行了多方面 权衡并取百家之长，从而设计结果 无论是在理论上，还是技术上都取得了较大 领先。此设计中含有生产的具体工艺流程，并对各个 设备进行了简洁设计,对主要设备反应釜的各个部件开展了周密 设计和详尽 计算，将并且衡量 了反应过程中将要使用到的物料以及能量。反应釜设备设计的内容和步骤,塔设备 强度和 定性 计算。在工艺流程设计以及车间设计方面，采纳AutoCAD 来完成，并进行了绘制。 三氯化磷是重要的化工原料,其在有机磷农药生产中发挥着着不可或缺的重要作用，当前工业 化生产所使用的工艺方法是在以往的方法基础上慢慢改善所建立的，从三种老工艺方法中脱颖而 出的三氯化磷底液法，此工艺完全能够在理论以及技术上达到市场所要求 标准，并且其生产工艺 较其它工艺方法而言更为简便，这对于未来工业生产中三氯化磷的运用来说是极为关键的一点。 关键词 ：三氯化磷;合成;氯化物;工艺设计 Production process design of phosphorus trichloride with annual output of 20 000 ton Gao Kai Directed by Associate professor Li Yan-Li Abstract This paper introduces the production of phosphorus trichloride, and compares its reaction principle, production process and method. It provides an academic and practical basis for the production and construction of phosphorus trichloride, and combines the advantages of various processes in the process flow, so as to give a design result that both the theoretical water level and technical level reach the leading level. This design contains the specific process flow of production, and the simple design of each equipment, the main equipment of the reactor of each component of the calculation and design, the reaction process of the material and energy balance. Design content and steps of reactor equipment, calculation of strength and stability of tower equipment. AutoCAD was used to design chemical process and workshop, and drawing was done. Phosphorus trichloride is an important chemical raw material, which can play a great potential in the organophosphorus pesticide production, currently in use process is gradually improved, from the three stand out from the old process method of phosphorus trichloride bottom liquid method, this method both in
