解析反應(yīng)釜與攪拌器

Analytical reaction kettle and agitator

555000jcjc線路檢測中心認為反應(yīng)釜廣泛應(yīng)用于石油、化工、橡膠、農(nóng)藥、染料、醫(yī)藥、食品等生產(chǎn)型用戶和各種科研實驗項目的研究，用來完成水解、中和、結(jié)晶、蒸餾、蒸發(fā)、儲存、氫化、烴化、聚合、縮合、加熱混配、恒溫反應(yīng)等工藝過程的容器。反應(yīng)釜根據(jù)不同的生產(chǎn)工藝、操作條件等不盡相同，反應(yīng)釜的設(shè)計結(jié)構(gòu)及參數(shù)不同，即反應(yīng)釜的結(jié)構(gòu)樣式不同，屬于非標儀器設(shè)備，致研科技長期致力于非標反應(yīng)釜設(shè)備的研發(fā)設(shè)計，有著深厚的技術(shù)積累，產(chǎn)品的質(zhì)量也得到廣大科研用戶的認可。 反應(yīng)釜的攪拌器是化學工程和生物工程中最常見也是最重要的單元設(shè)備之一。目前，攪拌器的選型和內(nèi)構(gòu)件的設(shè)計在很大程度上依賴試驗和經(jīng)驗，對放大規(guī)模還缺乏深入的認識，對于能耗和生產(chǎn)成本只能在一定規(guī)模的生產(chǎn)裝置上對比后才能得出結(jié)論，由于對產(chǎn)品的回收率和質(zhì)量要求越來越高，對攪拌器的研究日趨深入，已從早期對攪拌功率和混合時間的研究，20世紀80年代對反應(yīng)釜內(nèi)的流體速度場分布的研究，進入20世紀90年代以來的攪拌釜內(nèi)三維流場的數(shù)值模擬研究。流場數(shù)值模擬必須在深入進行流體力學研究的基礎(chǔ)上，綜合考慮流體流動的三維性、隨機性、非線性和邊界條件不確定性。通過數(shù)值模擬不但可以解決反應(yīng)器的放大機理，而且可以優(yōu)化設(shè)計開發(fā)新型高效攪拌器，使機械攪拌器的設(shè)計理論更加完善。

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.
