用DTB型结晶器从工业芒硝中制取无水硫酸钠

Using DTB Crystallize Get Anhydrous Sodium Sulfate from the Industry Coarse Decahedrons Sodium Sulfate

论述了采用DTB型结晶器从工业粗制芒硝中制取无水硫酸钠的工艺条件以及采用真空蒸发结晶法的原因。研究了不同结晶条件对产品粒度及质量的影响。

In this paper the technological crystallize condition of get anhydrous sodium sulfate from the industry coarse decahedrons sodium sulfate by using DTB crystallize is discussed ,and the reason why the vacuum evaporation crystal used is given. The influent of granularity and quality under different condition is studied.
