High-flux micro-channel reactor

Abstract

The invention discloses a high-flux micro-channel reactor. The reactor comprises a plurality of reaction units which are overlapped, wherein each reaction unit comprises a substrate which is horizontally arranged; an air guide groove is formed in the substrate; a first locating slot is formed by horizontally extending outwards in the circumferential direction of the air guide groove; a second locating slot is formed by horizontally extending outwards in the circumferential direction of the first locating slot; a cooling liquid inlet hole, a cooling liquid outlet hole and an air inlet hole areformed in the substrate; a gas injection plate is clamped in the first locating slot; a heat exchange plate is clamped in the second locating slot; the two opposite sides of the heat exchange plate and the side wall of the second locating slot form two drainage grooves with the bottom of the second locating slot as the bottom face; a flow guide groove is formed in the surface of the heat exchangeplate; a plurality of through heat exchange holes are formed at intervals in the end face of the heat exchange plate; and the two ends of the multiple heat exchange holes are communicated with the twodrainage grooves correspondingly. According to the invention, the gas-liquid-solid three-phase contact is sufficient, the yield is high, the channel is large in size but not easy to block, the batchindustrial production can be realized, and the industrial production requirements are met.

Description

technical field [0001] The invention relates to the technical field of microreactors, in particular to a high-throughput microchannel reactor. Background technique [0002] At present, there are mainly two types of gas-liquid-solid reactors, one is the traditional tank reactor, and the other is a small microchannel (10-1000 μm) reactor, but these two reactors have their own advantages and disadvantages. Advantages and disadvantages: the tank reactor has a wide range of applications, less investment, and is easy to put into production. However, the heat exchange area of ​​this type of reactor is small, the reaction temperature is not suitable for control, and the residence time is inconsistent. The product reaction cycle is long and the yield is not ideal; Microchannel reactors can fully solve the problems of small heat transfer area, long reaction cycle and yield, but the channel size of microchannel reactors is very small, and the particles in the raw materials have a certa...

[0002] At present, there are mainly two types of gas-liquid-solid reactors, one is the traditional tank reactor, and the other is a small microchannel (10-1000 μm) reactor, but these two reactors have their own advantages and disadvantages. Advantages and disadvantages: the tank reactor has a wide range of applications, less investment, and is easy to put into production. However, the heat exchange area of ​​this type of reactor is small, the reaction temperature is not suitable for control, and the residence time is inconsistent. The product reaction cycle is long and the yield is not ideal; Microchannel reactors can fully solve the problems of small heat transfer area, long reaction cycle and yield, but the channel size of microchannel reactors is very small, and the particles in the raw materials have a certain agglomeration phenomenon in the production process, which makes microchannel reactors It is often blocked, and the biggest disadvantage of microchannel reactors is that its processing capacity is very limited, staying at the laboratory level, and it is difficult to apply to mass production

If there are too many microchannel reactors, the structure of the integrated reactor device will be very complicated, and it will be difficult to detect and control the state of a single microchannel reactor, which will virtually increase the cost of industrial application.
