浅述反循环工艺原理及运行问题

Talk about the Principles of Counter-circulation and the Questions of Operating

目前国内真空制盐生产工艺种类较多 ,采用不同的蒸发工艺所产出NaCl晶体的粒度也各不相同。而NaCl晶体粒度直接影响着晶体的纯度及流动性。河南省平顶山盐厂是国内首家采用反循环径向出料蒸发工艺的厂家。

Now there are many kind of salt making processes in the country, but different granularity will be produced by the dissimilar evaporation. The granularity of NaCl effects the purity and flowability of crystal. The Pingdinshan Salt Plant first used the counter-circulation process with radically discharged in the country. Author discusses primarily the mechanism of counter-circulation and the effects to the granularity of crystal.
