解析反应釜与搅拌器
Analytical reaction kettle and agitator
贵阳白水泥认为反应釜广泛应用于石油、化工、橡胶、农药、染料、医药、食品等生产型用户和各种科研实验项目的研究，用来完成水解、中和、结晶、蒸馏、蒸发、储存、氢化、烃化、聚合、缩合、加热混配、恒温反应等工艺过程的容器。反应釜根据不同的生产工艺、操作条件等不尽相同，反应釜的设计结构及参数不同，即反应釜的结构样式不同，属于非标仪器设备，致研科技长期致力于非标反应釜设备的研发设计，有着深厚的技术积累，产品的质量也得到广大科研用户的认可。 反应釜的搅拌器是化学工程和生物工程中最常见也是最重要的单元设备之一。目前，搅拌器的选型和内构件的设计在很大程度上依赖试验和经验，对放大规模还缺乏深入的认识，对于能耗和生产成本只能在一定规模的生产装置上对比后才能得出结论，由于对产品的回收率和质量要求越来越高，对搅拌器的研究日趋深入，已从早期对搅拌功率和混合时间的研究，20世纪80年代对反应釜内的流体速度场分布的研究，进入20世纪90年代以来的搅拌釜内三维流场的数值模拟研究。流场数值模拟必须在深入进行流体力学研究的基础上，综合考虑流体流动的三维性、随机性、非线性和边界条件不确定性。通过数值模拟不但可以解决反应器的放大机理，而且可以优化设计开发新型高效搅拌器，使机械搅拌器的设计理论更加完善。
Research reactors are widely used in petroleum, chemical, rubber, pesticide, dyestuff, pharmaceutical and food production and scientific research user experiment project, the container used to complete hydrolysis, neutralization, crystallization, distillation, evaporation, storage, hydrogenation, alkylation, polymerization, condensation, heating, mixing, constant temperature reaction process. The reaction kettle according to different production process, operating conditions are not the same, the design of the structure and parameters of the reactor, the reactor structural style is different, non-standard equipment design, research and development of scientific and technological research to long-term commitment to non-standard reactor equipment, with strong technical accumulation, product quality the research of user acceptance. The agitator of the reactor is one of the most common and most important unit equipment in chemical engineering and biological engineering. At present, the selection and design of agitator components depends on the test and experience to a large extent, to enlarge the scale is still lack of in-depth understanding, for energy consumption and production cost only compared the production unit in certain scale after in order to draw conclusions, due to the recovery rate and quality of the products have become increasingly demanding, research on the stirrer more thorough, from the early studies of stirring power and mixing time, study on the distribution of fluid velocity in 1980s of the autoclave, to study numerical simulation of three-dimensional flow field in stirred tank since 1990s in. The numerical simulation of fluid flow must be based on in-depth study of fluid mechanics, considering the uncertainty, randomness, nonlinearity and boundary conditions of fluid flow. Numerical simulation can not only solve the amplification mechanism of the reactor, but also optimize the design and development of the new efficient stirrer, and make the design theory of mechanical agitator more perfect.
