回顾国内外饲料级磷酸氢钙市场,并对未来市场需求进行预测。在当前普遍采用的工艺、工程技术的基础之上,笔者结合多年的工程实践,设计出了一些新的装置和方案如生石灰消化和配乳,导流管式单槽单桨或特殊结构的单槽双桨磷酸反应槽,连续式脱氟(一段中和)反应槽,白磷肥分离装置等,同时还进行了经济效益分析。
Review domestic and international feed grade dicalcium phosphate market, and predict the future market demand. Based on the current commonly used technology and engineering technology, the author has designed some new devices and solutions such as quicklime digestion and milk mixing, single-slot single-slot draft tube or single structure with special structure based on years of engineering practice Slot dual-phosphoric acid reaction tank, continuous defluorination (a period of neutralization) reaction tank, white phosphorus fertilizer separation device, also conducted a economic analysis.
