磷酸氢钙装置中石灰乳制备工艺的改进

石灰乳是磷酸氢钙生产所需的原料之一,其制备工艺对磷酸氢钙产品的品质、生石灰消耗量和石灰渣排放量都有较大影响。通过改进生石灰的储存方式、消化工艺以及石灰浆的净化方式,实施后使每吨磷酸氢钙产品的生石灰消耗量降低约33%、石灰渣排放量减少约67%,并提升了石灰乳以及磷酸氢钙产品的品质,取得了良好的应用效果。

Improvement of Lime Milk Preparation Process for Dicalcium Phosphate Dihydrogen

Lime milk is one of materials needed for the production of dicalcium phosphate dihydrogen （DCPD） , and its preparation process has a great effect on the product quality, lime consumption and lime sludge emission. The improvements of lime storage method, lime slaking technology and lime slurry purifica- tion method in this paper got a good applying effect that the lime wastage was reduced by about 33% and the lime sludge was reduced by about 67% for a ton DCPD, and the qualities of lime milk and DCPD were enhanced.
