MgO is extensively used for various applications. A Venturi jet reactor can help prepare the micro- or nano-sized magnesia via pyrolysis. However, the reactors have an uneven mixing and concentration distribution. The operational and structural parameters of the reactor have therefore been optimized to overcome this issue. The numerical simulations indicate that higher flow rates of MgCl₂ at the inlet yield higher reactor temperatures and higher MgO product concentrations. The ideal diameter ratio between the straight tube and the throat of the reactor is 5/2 with an angle between the draft tube and the throat of 90° and a draft pipe with a diameter of 25 mm. Our results provide data support for the design optimization of pyrolysis reactors.

微量纳米氧化镁氧化镁喷射热解工艺的优化

MgO被广泛用于各种应用。文丘里射流反应器可通过热解帮助制备微米级或纳米级氧化镁。但是，反应器的混合和浓度分布不均匀。因此，已经优化了反应器的操作和结构参数以克服该问题。数值模拟表明，入口处较高的MgCl ₂流速产生较高的反应器温度和较高的MgO产物浓度。反应器的直管与喉管之间的理想直径比为5/2，引流管与喉管之间的夹角为90°，引气管的直径为25 mm。我们的结果为热解反应器的设计优化提供了数据支持。
