Micro-channel reactor manufactured based on 3D printer technology

Abstract

The invention relates to the technical field of chemical engineering devices, in particular to a micro-channel reactor manufactured based on a 3D printer technology. According to the technical scheme, the micro-channel reactor comprises at least one micro-reaction channel module unit printed through the 3D technology, the micro-reactor module unit is a square body, a plurality of regularly-arranged micro-channel reaction tubes are embedded in the micro-reactor module unit, the micro-channel reaction tube is simultaneously provided with an inner-layer heat exchange medium cavity, a material reaction cavity and a surrounding heat exchange medium cavity; and the inner-layer heat exchange medium cavity is located in the center of the micro-channel reaction tube, the surrounding heat exchange medium cavity is surrounded by the material reaction cavity, and the surrounding heat exchange medium cavity surrounds the material reaction cavity. The reaction cavity in the micro-channel increases the reaction contact area and time length through the action of a spiral flow guide partition plate structure and a baffle plate, so that reaction materials can be mixed more fully and uniformly, the reaction is promoted to be carried out quickly and stably, and the reaction rate and the product quality are improved.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a microchannel reactor manufactured based on 3D printer technology. Background technique [0002] Microchannel reactor, also known as microreactor or microflow reactor, etc., its essence is to make fluid pass through mechanical channels with equivalent diameters ranging from microns to millimeters, and force gas-liquid, liquid-liquid, gas-liquid-liquid, etc. to mix. , in order to achieve the purpose of increasing the mass transfer and heat transfer interface and improving the efficiency of mass transfer, heat transfer and reaction. [0003] The traditional microchannel reactor initially uses metal materials to combine two pieces into one. The structure is relatively simple, and after a period of use of the microchannel reactor with this structure, the reactor pipeline goes through the process of repeated thermal expansion and contraction. There will be leakage at the ...

AI Technical Summary

Problems solved by technology

In order to mix materials as evenly as possible, traditional microchannel reactors often make different designs and changes in the shape of the reaction channel, which can easily lead to unreasonable utilization of processing materials.

At the same time, since the characteristic size of the microchannel reactor is at the micron level, it is difficult for the traditional precision manufacturing technology to realize the manufacture of more complex microstructures inside the microchannel reactor, and cannot meet some reactions with stricter requirements.
