Accurate feeding continuous-flow reaction system capable of quenching

Abstract

The present invention relates to the technical field of pharmaceutical chemical engineering equipment, and more particularly to an accurate feeding continuous-flow reaction system capable of quenching. The accurate feeding continuous-flow reaction system capable of quenching is characterized by comprising a feeding unit, a quenching unit, a CIP cleaning unit and a reaction unit, wherein the reaction unit comprises a shell, and an upper end and a lower end of the shell are connected to a tube sheet and a baffled channel, respectively. According to the present invention, the reaction unit can becleaned rapidly and thoroughly by using the CIP cleaning unit; with a first hydraulic diaphragm metering pump capable of accurately adjusting an instantaneous flow rate and a first flow rate calibration column capable of accurately measuring an instantaneous flow rate, an instantaneous flow rate can be displayed, and the problem that the quantity of reactants entering the reaction unit cannot beaccurately controlled is resolved; and by using the quenching unit, residual reactants in the product are eliminated, and the problem that excessive reactants cannot be eliminated by a quenching reaction after the reaction is completed is resolved. In addition, a catalyst is arranged in the baffled channel to catalyze the reactants multiple times, and meanwhile, the catalyst can be replaced conveniently to adapt to different reactions.

Description

technical field [0001] The invention relates to the technical field of chemical and pharmaceutical equipment, in particular to a precise feeding continuous flow reaction system capable of quenching. 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 tube length of the continuous flow tube reactor is long and the tube diameter is small, so the traditional cleaning method cannot be applied to the cleaning of the continuous flow tube reactor. At the same time, the existing continuous flo...
