a microreactor

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 present invention relates to the technical field of reaction equipment, especially microchannel reactors used in chemical, pharmaceutical and other industries. The medium can be gas, liquid or dispersion, and is used for reactants to carry out physical reactions or chemical reactions in its channels. reaction. Background technique [0002] A microreactor, also known as a microchannel reactor, is a three-dimensional structural element made from a solid matrix using special micromachining technology that can be used to carry out chemical reactions. Microreactors typically contain small channel sizes and channel diversity in which fluids flow and in which desired reactions occur. [0003] The "micro" of the microreactor does not specifically refer to the size of the microreactor equipment, nor does it refer to the small output of the microreactor equipment product, but means that the channels of the process fluid are at the micron level, and the micr...

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
