Microchannel reactor

Abstract

The invention provides a microchannel reactor including an inner sleeve tube and an outer sleeve tube which sleeves the periphery of the inner sleeve tube. An accommodating groove is formed on the outer wall of the inner sleeve tube and / or the inner wall of the outer sleeve tube. The microchannel reactor also includes an insert sheet structure capable of being inserted in the accommodating groove,so that flowing channel for a reaction fluid is defined by cooperation of the inner sleeve tube, the outer sleeve tube, the accommodating groove and the insert sheet structure; the insert sheet structure includes a first insert sheet and a second insert sheet that are arranged in a laminated manner, wherein the first insert sheet has a first flowing trough in a first extending direction while thesecond insert sheet has a second flowing trough in a second extending direction, the first extending direction being crossed with the second extending direction, so that the fluid can flow alternatively in the first extending direction and the second extending direction. The microchannel reactor, compared with traditional single-layer microchannel reactors, is reinforced in shear effect in vertical direction, thus enhancing mixing effect and increasing flow quantity of reaction materials. The microchannel reactor can satisfy industrial production in large yield requirement.

Description

technical field [0001] The invention belongs to the technical field of micro-reactions, and in particular relates to a micro-channel reactor. Background technique [0002] The microreactor provides a millimeter-scale channel form for chemical reactions that are complex, violent, exothermic or endothermic, high-viscosity or easy to hang on the wall. The residence time and the number of tubes can be changed to maximize industrial scale-up, and A microchannel reactor with ideal temperature control. Existing reactors mostly use microchannels with turbulence structures engraved or processed on a flat plate, but in this microchannel structure, due to the blocking effect of the turbulence structure in the channel, the flow rate of the reaction materials in the microreactor will be relatively low. Small, it can only be used in laboratory or small-scale production, and it is difficult to apply to industrial production with large output requirements. [0003] Because the flow rate o...

Problems solved by technology

Existing reactors mostly use microchannels with turbulence structures engraved or processed on a flat plate, but in this microchannel structure, due to the blocking effect of the turbulence structure in the channel, the flow rate of the reaction materials in the microreactor will be relatively low. Small, can only be used in laboratory or small-scale production, it is difficult to apply to industrial production with larger output requirements

[0003] Because the flow rate of the reaction material in the microreactor is relatively small in the microchannel reaction heat exchange device in the prior art, it can only be applied to laboratory or small-scale production, and it is difficult to apply to the medium technical problems of industrialized production with larger output requirements. Therefore the present invention studies and designs a kind of microchannel reactor
