Reactor unit and double-sided microreactor system

Abstract

The invention provides a reactor unit and a double-sided microreactor system. The reactor unit comprises a mixing channel, wherein at least two inlet channels and at least two outlet channels are respectively arranged at two ends of the mixing channel; a first gathering part is formed at communicating parts between the at least two inlet channels and the mixing channel, and is a reactant impact area; a second gathering part is formed at communicating parts between the at least two outlet channels and the mixing channel, and is a reactant vortex area; a flow surrounding column required for forming a vortex is arranged in the mixing channel close to one side of the second gathering part. The double-sided microreactor system comprises a reaction plate; a plurality of reactor units are arranged on the reaction plate. According to the reactor unit and the double-sided microreactor system provided by the invention, the problems that reactants are stagnated and accumulated, block a flow channel and the like because of fluid stagnation points in the application process of a microreactor can be solved; besides, the problems of deformation due to asymmetric arrangement of the plurality of reactor units and non-uniform temperatures at two sides in the application process can be solved.

Description

technical field [0001] The invention relates to the field of micro-reactors, in particular to a reactor unit and a double-sided micro-reactor system for optimizing and controlling chemical reaction processes by means of mesoscopic-scale impact flow and flow around a column to enhance mixing. Background technique [0002] A microreactor is a small reaction system manufactured by precision machining technology, and the size of the internal flow channel is on the order of microns to several millimeters. The main function of the microreactor is to enhance the mass and heat transfer process and improve the fluid flow mode, and its main enhancement is the transfer characteristics. In the microreactor, as the line scale decreases, the gradient of some physical quantities increases rapidly, which leads to the increase of mass transfer and heat transfer driving force, and expands the diffusion flux per unit volume or unit area, which is very important for chemical reactions. importa...
