Abstract

The invention belongs to the technical field of chemical micro-reaction equipment, and particularly relates to a micro-channel reactor. According to the technical scheme, the reactor comprises a reactor shell, an upper-end flow guide base plate, an upper-end sealing cover, a lower-end flow guide base plate, a lower-end sealing cover, reaction micro-channels and a heat-conducting medium cavity, anda material inlet penetrates through the upper-end sealing cover and communicates with the multiple reaction micro-channels connected in parallel through the upper-end flow guide base plate; A material outlet penetrates through the lower-end sealing cover and then communicates with a reaction micro-channel through the lower-end flow guide base plate, and the reaction micro-channel is a linear or curved integrated columnar channel. An integrated micro-reaction tube is used as a reaction tube bundle, so that leakage of the reactor is avoided, and the service life of the micro-channel reactor isprolonged; the inner surface of the pipeline of the micro-reaction tube is roughened by adopting acid etching, coating or high temperature and other technical treatment modes, so that the specific surface area of the reactor is increased, the turbulence effect is enhanced, reaction materials are mixed more fully, and the reaction rate is increased.

Description

technical field [0001] The invention belongs to the technical field of chemical micro-reaction equipment, in particular to a micro-channel reactor. Background technique [0002] Microchannel reactor, also known as microreactor, usually contains small channel size and channel diversity. It is a device that can be used for chemical reactions manufactured with the help of special micromachining technology and solid substrate. Compared with conventional reactors, microchannel reactors have the characteristics of small volume, large specific surface area, continuous process, and easy scale-up. The unique structure of the microreactor makes it have very high heat transfer and mass transfer efficiency, which can make the reaction layer close to a constant temperature, which is beneficial to the progress of various chemical reactions, and is applied in many fields at the same time. At the same time, the use of continuous flow microchannel reactors with different structures can real...
