详细介绍

产品特点/Product Features

具有分级功能的OSLO结晶器通常被用来生产希望具有较大颗粒的产品。晶体在过饱和液流中流化悬浮，为晶体生长提供了一个好的流场条件。系统过饱和度产生于外置换热器，晶体生长区域设置在结晶器下部。过饱和液被送到结晶器底部，在上升的过程中穿过晶体床层，逐步消除过饱和，晶体逐渐长大。
通常我们将它设计成为一个具有大直径的澄清区域的结晶器。消除过饱和后的溶液经过澄清后才被泵抽吸离开，去获得新的过饱和。它的优点在于循环母液中晶体颗粒含量较少，从而大的降低泵叶轮和晶粒之间的接触几率，降低二次成核的速率，为培养大颗粒晶体提供必要条件。
OSLO Crystallizer is used for producing larger size crystals with its classifying function. The crystals are fluidized and suspended in a supersaturated liquid which provided an excellent flow field condition for crystals growth.The system supersaturation is generated from the external heat exchanger. The crystal growth region is arranged at the lower part of the crystallizer. Supersaturated liquid is delivered to the bottom of the mold and passes through the crystal bed as it rises. It gradually eliminates supersaturation and grows up.
We usually design it as a mold with a large diameter of clear area. After removing the supersaturated, the solution is clarified and pumped away to obtain a new supersaturation. The content of crystal particles in circulating mother liquor is less, thereby greatly reducing the contact probability between the impeller and the grain of the pump, lowering the rate of second nucleation providing the necessary conditions for the c*tion of large grain crystals.

适用范围/Applied Range

适用于晶体颗粒良好，母液粘度不高的产品低温（或冷冻）结晶的场合，如十水硫酸钠、氯化铵、硝酸钠、过硫酸盐、碳酸盐、草酸盐等。
Suitable for products with good particle size of crystals and low viscosity of mother liquor crystallized in low temperature (or freeze) environment. such as sal glauberi, ammonium chloride, sodium nitrate, persulfate, carbonate, oxalate and so on
