摘　　要：在二氧化钛的生产工艺中,真空结晶是非常重要的工艺环节,目前大多数厂家采用一级水环真空泵加两级蒸汽喷射泵形成高真空工艺来进行结晶蒸发,本研究通过采用干式真空系统替代现有系统,达到不使用大量蒸汽和水的目的,降低能耗的同时解决了长期困扰的气温对结晶效率及产品质量的影响。In the production process of titanium dioxide,vacuum crystallization is a very important process.At present,most manufacturers use a first-stage water ring vacuum pump and a two-stage steam jet pump to form a high vacuum process for crystallization evaporation.In this paper,a dry vacuum system was used to replace the existing system,to achieve the goal of not using large amounts of steam and water,reducing energy consumption,and solve long-term turbulence problems of the effects of temperature on crystallization efficiency and product quality.
