Novel continuous flow coupling reactor for rapid strong exothermic reaction

Abstract

The invention discloses a novel continuous flow coupling reactor for rapid strong exothermic reaction. The novel continuous flow coupling reactor comprises a reactor shell; a microstructure mixer anda large-flux tubular reactor are arranged in the reactor shell from top to bottom, and an inlet of the large-flux tubular reactor is connected with an outlet of the microstructure mixer; the microstructure mixer is used for efficiently mixing and dispersing the reaction materials, accurately controlling the temperature and quickly leading the uniformly mixed reaction materials into the rear-end high-flux tubular reactor for reaction; and the large-flux tubular reactor is provided with an inner heat exchange tube and an outer heat exchange jacket, and provides heat exchange quantity required byreaction. According to the novel continuous flow coupling reactor system, the mixer with the microstructure and the large-flux tubular reactor are combined together for reasonable optimal matching, and when large-flux operation is carried out, what is guaranteed is that the reactor has efficient mixing, mass transfer and heat transfer performance; and the heat exchange area of the reactor can beflexibly adjusted by adjusting different sizes and bending modes of the inner heat exchange tubes.

Description

technical field [0001] The invention relates to a technology in the field of chemical fast mixing and reaction equipment, in particular to a novel continuous flow coupling reactor system for fast and strong exothermic reaction. Background technique [0002] The chemical reaction process, especially the fast and strongly exothermic heterogeneous reaction process, puts forward high requirements on the mixing and transfer performance of the reaction equipment. Traditional reaction devices often fail to achieve ideal reaction effects due to complex flow phenomena in the reaction system and uneven distribution of temperature field and concentration field in the reactor, which also makes the operation of the reactor and precise control of reaction conditions very difficult. In order to avoid these problems, the traditional reaction process is often operated under conditions such as low load and a large amount of product reflux to reduce the risk of the reaction process, but this m...

[0005] The present invention aims at the severe back-mixing and low mass and heat transfer rate in the existing reactor technology, which leads to low reaction efficiency. For the rapid and strong exothermic reaction, the increase of the reactor size during the reactor enlargement process leads to Uneven heat distribution leads to a decrease in reaction selectivity. A new continuous flow coupled reactor system for fast and strong exothermic reactions is proposed. When the reactor is operated with a large flux, it is ensured that the reactor has efficient mixing, mass transfer and heat transfer performance, and the uniform distribution of the concentration field and temperature field in the reactor is realized, and the flexible adjustment of the heat exchange area of ​​the reactor can be realized
