    • PROBLEM TO BE SOLVED: To reduce the circulation amount of a heating medium for transferring heat in a multi-tubular reactor where an exothermic or endothermic gaseous reaction proceeds and at the same time uniformalize the inside wall temperature distribution of reaction tubes on a plane crossing of longitudinal direction of reaction tubes. SOLUTION: The reactor 1 is equipped with the reactor tubes 3 charged with a catalyst through which reactant gas flows, the heating medium liquid flows around the reaction tubes in a reaction zone 12. Multiple baffles 34 are fixed to surround the reaction tubes to improve heat transferring conditions. Baffles in this reactor are positioned and formed as described below. Specifically by the baffles, even if the circulation amount of heating medium is minimal or temperature difference in the longitudinal direction of the reaction tubes is large, the heat transfer is sufficiently enough and temperature difference in the cross-section of the tube bundle is surely to be sustained minimal. To uniformalize the temperature in the flow of the heating medium, furthermore a preheating zone 11 is positioned first in the reaction zone of the multi-tubular reactor, both zones are separated liquid-tightly from each other in the tube bundle section, the same heating medium stream flows through the both zones.

    • 要解决的问题:为了减少在放热或吸热气体反应进行的多管式反应器中传热的加热介质的循环量,同时使反应管的内壁温度分布均匀化 反应管纵向平面交叉。 解决方案:反应器1配备有反应器管3,其中装有反应气体流过的催化剂,加热介质液体在反应区12内围绕反应管流动。多个挡板34固定以包围反应管 以改善传热条件。 该反应器中的挡板如下所述地定位和形成。 特别是由挡板构成,即使加热介质的循环量少,反应管的长度方向的温度差大,则传热足够充分,管束的横截面的温度差肯定为 维持最小。 为了使加热介质的流动中的温度均匀化,此外,先将预热区域11定位在多管式反应器的反应区域中,两个区域在管束段中彼此液密地分离,将相同的加热 中等流量流过这两个区域。 版权所有(C)2006,JPO&NCIPI
