Heat collection and exchange system integrated silicon carbide micro-channel reactor

Abstract

The invention discloses a heat collection and exchange system integrated silicon carbide micro-channel reactor. The micro-channel reactor comprises a chip and a cover plate, wherein the cover plate ismounted on the chip; the chip comprises a first shell, a first heat exchange channel and a reaction channel; the cover plate comprises a second shell and a second heat exchange channel; and the reaction channel is formed in a contact surface between the first shell and the second shell, and the first heat exchange channel and the second exchange channel are respectively formed in the lower end surface of the first shell and the upper end surface of the second shell. According to the heat collection and exchange system integrated silicon carbide micro-channel reactor designed by the invention,the heat exchange of cooling liquid or heating liquid is realized by virtue of the first heat exchange channel and the second exchange channel, and the chemical reaction of reaction liquid is realized by virtue of the reaction channel, the structure is simple and efficient, and cold and hot mediums directly enter a reactor chip and are no longer conducted through metals, so that the conduction efficiency is greatly improved, and the cost is saved.

Description

technical field [0001] The invention relates to the field of microchannel reactors, in particular to a silicon carbide microchannel reactor integrating a heat exchange system. Background technique [0002] Reactor module, a basic device for microchannel chemical reaction, is equivalent to a reaction vessel, which can provide a reaction place for various high-risk chemical reactions, and microchannel reactor is an extremely important component. [0003] Microchannel reactors were originally made of metal materials. The structure is generally combined into one, which is relatively simple. Nowadays, silicon carbide microchannel reactors have the characteristics of corrosion resistance and high thermal conductivity, so they have become the focus of our attention. , but also the best choice for making microchannel reactors. [0004] At present, almost all silicon carbide microchannel reactors in the world use indirect heat transfer (cooling) for heat exchange operations, that is...

AI Technical Summary

Problems solved by technology

[0004] At present, almost all silicon carbide microchannel reactors in the world use indirect heat transfer (cooling) for heat exchange operations, that is, a heat exchange device made of metal is attached to the outside of the silicon carbide reactor chip. There is a cavity inside the heat exchange plate, which is heated and refrigerated by injecting heat (cold) medium into the exchanger; this is the method adopted by most manufacturers at present, and this method is an indirect heat conduction method. There is always a loss of energy and efficiency
