本文比较了目前国内几种常用的生产氯化钡的工艺流程,通过对工艺流程和影响产率的因素的分析,对结晶工艺过程进行了适当的改进,以毒重石残液为原料,用真空旋转蒸发结晶氯化钡的工艺方法,探究出最佳的工艺条件是水浴温度在85℃~90℃,控制旋转速率为42ran/min,维持真空度在0.085Mpa下,能生产高纯度的氯化钡产品.通过对结晶产品中的钙、镁、硫、铁含量的分析和讨论发现,原料液在循环利用后,氯化钡的纯度能达到98%左右.此外,由于原料液在蒸发结晶过程中对反应装置的材料有比较大的腐蚀性,探究了硫化钠对反应器的防腐蚀效果,得出在加入一定量的硫化钠后,在一定的时间段内对反应器的材料有保护作用.

介个太专业了……我试试看翻译一下吧~
This paper compares the current domestic common production of barium chloride,and makes some appropriate improvement on the process of crystallization according to the analysis of the processes and factors influencing the yield,that is,using the poison tungsten residue as raw material, taking the vacuum rotary as the method to evaporate the crystallized barium chloride.

The paper finds out the best conditions of production are bath temperature at 85 ℃ ~ 90 ℃,rotation rate at 42ran/min and the vacuum degree at 0.085Mpa , under such conditions high purity barium products can be produced.

Based on the analysis and discussion on the contents of calcium, magnesium, sulfur,iron of the crystallized products,the purity of barium chloride can reach about 98% after the recycling of the material liquid.

Furthermore, for the material liquid is strongly corrosive to material of the reaction apparatu during the process of crystallization,the paper examines the protection of apparatu by Sodium sulfide against the corrosion, resulting in the fact that adding a certain amount of Sodium sulfide, the material of the reactor can be proteced in a certain period of time.
