Micro-reactor

Abstract

The invention discloses a micro-reactor. The micro-reactor is provided with a reaction channel; the reaction channel is provided with a plurality of reaction cavities (12), and each reaction cavity (12) is internally provided with a diversion body (15) and a spoiler body (16); all the reaction cavities (12) are respectively in a rectangle; an outlet of each reaction cavity (12) comprises a V-shaped channel (17) and a linear channel (18), wherein the widths of the V-shaped channels (17) are reduced gradually, and the widths of the linear channels (18) are the same as one another; the widths a of the linear channels (18) are 0.002-6mm, and the ratios of distances b between the spoiler bodies (16) and two sides of the V-shaped channels (17) to the widths a of the linear channels (18) are equal to 0.93-2.2. The micro-reactor has a high specific surface area so as to augment and strengthen a reaction process, thus further increasing liquid holdup and handling capacity, effectively improving the conversion rate and yield of products and remarkably improving coefficient of heat conduction and heat exchange effect; furthermore, when a medium passes through a channel, the pressure drop is greatly reduced, so that the micro-reactor is beneficial to accurate control of reaction conditions and reduction of energy consumption.

Description

technical field [0001] The invention relates to the technical field of reaction equipment, in particular to microchannel reactors used in industries such as chemical industry and medicine. reaction. Background technique [0002] A microreactor, that is, a microchannel reactor, is a three-dimensional structural element that can be used for chemical reactions manufactured from a solid matrix by means of special micromachining techniques. Microreactors generally contain small channel sizes and channel multiplicity in which fluids flow and where desired reactions take place. [0003] The "micro" of the microreactor does not refer specifically to the size of the microreactor equipment, nor does it mean that the output of the microreactor equipment is small, but means that the channel of the process fluid is at the micron level, and the microreactor can contain components. Millions of microchannels and thus also high throughput. [0004] The size of the microreactor is much sma...

Problems solved by technology

[0007] Secondly, it is not pressure-resistant and cannot perform high-pressure reactions. For example, some fluids may vaporize under low-pressure conditions, so they need to be reacted under high-pressure conditions

If the above-mentioned microreactor is used, it will result in the inability to complete the mixing or reaction

[0008] Furthermore, the characteristic size of the microreactor is generally between 10 and 3000 μm, and its streamlined structure requires special processing techniques and molds, which increases the difficulty and cost of processing and manufacturing, and is not conducive to large-scale production
