Description

technical field [0001] The invention relates to the technical field of chemical industry and pharmacy, in particular to a continuous flow tube reaction system and a reaction control system. Background technique [0002] Reactor equipment commonly used in the field of chemical and pharmaceutical technology includes tubular reactors and tank reactors, etc. Among them, tank reactors are often equipped with stirring devices in the reactor for mixing liquid phase reactants. The conversion rate is low, and the energy consumption and pollution are serious. Due to the high requirements for the purity of products in the chemical and pharmaceutical fields, the commonly used reactor equipment is a continuous flow tube reactor. [0003] The concentration and reaction rate of chemical reactants in the tubular reactor change with the length of the tube, so the tubular reactor needs to meet the tube length required by the chemical reaction, and the existing straight tube reactor or U-shap...
