Reactor for preparing ultramicro-granules

The utility model relates to a reactor to produce superfine particle, in particular to a reactor which has even number porous rotating blades and is used to produce superfine particle. The utility model discloses a reactor which has even number internal porous rotating blades. The porous rotating blades breaks the liquid injected from a rotating spindle into micro drips, a gas guided into the reactor makes mass transfer with the liquid on the surface of the micro drips and makes crystal growth reaction. Because the reactant required for the crystal growth is limited by the micro-drips, the crystal growth reaction is stopped due to the lack of the reactant, and thus the crystallized grain is limited within the nanometer scope. The reactor of this utility model can also be applied to the liquid-liquid reaction, wherein, two different liquids are sprayed from the rotating spindle respectively and are broken into micro-drips by the porous rotating blades and are contacted and reacted with each other to form superfine particle. 本实用新型是关于一种用于制备超微颗粒的反应器，尤其有关一种含有复数个多孔性旋转叶片的用于制备超微颗粒的反应器。本实用新型揭示一种内部含有复数个多孔性旋转叶片的反应器。该多孔性旋转叶片将从一旋转轴心喷出的液体打散成为微液滴状，一被导入该反应器的气体透过微液滴的表面与液体进行质量交换，并进行长晶反应。由于晶体成长所需要的反应物被微液滴所限制，使得长晶反应由于缺少需要的反应物而停止，进而控制结晶颗粒于纳米的范围。本实用新型的反应器也适用于液-液之间的反应，其中两不同的液体分别被从旋转轴心喷出，而为该多孔性旋转叶片打散成为微液滴状，并互相接触反应，形成超微颗粒。
