Efficient mixing heat exchange micro-channel reactor

Abstract

The invention discloses an efficient mixing heat exchange micro-channel reactor. The efficient mixing heat exchange micro-channel reactor comprises a dispersive mixing component, multiple reaction liquid passageway matrixes and heat exchange medium passageway matrixes. The reaction liquid passageway matrixes and the heat exchange medium passageway matrixes are arranged alternately. The dispersive mixing component is provided with dispersive mixing channels allowing two or more kinds of reaction liquid to dispersively flow in and be mixed to form mixed reaction liquid. The reaction liquid passageway matrixes are provided with reaction liquid passageways and heat exchange medium via holes. The heat exchange medium passageway matrixes are provided with reaction liquid via holes, heat exchange medium passageways, inflow holes and outflow holes, wherein the inflow holes and the outflow holes are communicated with the heat exchange medium passageways. The reaction liquid passageways of every two adjacent reaction liquid passageway matrixes are of a cascaded structure. The heat exchange medium passageways of every two adjacent heat exchange medium passageway matrixes are of a parallel structure. According to the efficient mixing heat exchange micro-channel reactor, the heat transfer problem is completely solved; mass transfer and heat transfer are enhanced, input of heat and cold is reduced, use of a solvent is reduced, the reaction yield is increased, energy is saved, consumption is reduced, and the efficient mixing heat exchange micro-channel reactor is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of organic chemical synthesis, in particular to a high-efficiency mixing heat-exchanging microchannel reactor for micro-continuous flow of chemical reactions, which is a micro-continuous liquid device. Background technique [0002] The microchannel reactor is a microchemical reaction system with a unit reaction interface scale of micron to millimeter level. Its characteristics are as follows: (1) large specific surface area; (2) enhanced mass and heat transfer; (3) energy saving and consumption reduction; ( 4) Safety, because the volume of the reaction is much smaller than that of the traditional reactor, and the mass and heat transfer is enhanced, so the risk factor in the reaction process is greatly reduced; [0003] In the known technology, in some chemical reactions, when two or more fluids are mixed and reacted, they need to be fully dispersed and mixed, and the reaction temperature should be precisely ...
