Embodiment 1

[0039] Such as figure 1 , the microreactor includes a reaction channel 1 and heat exchange channels 17 located on both sides of the reaction channel 1 .

[0040] Such as figure 2 , the reaction channel 1 has 20 first reaction chambers 2 , every five first reaction chambers 2 are connected end to end to form a reaction chamber group 20 , and the reaction channel 1 is formed by four reaction chamber groups 20 connected in parallel. A plurality of third fluid inlets 18 and a plurality of third fluid outlets 19 are provided in the reaction channel 1 for fluids to flow into or out of the reaction channel 1 respectively. The third fluid inlet 18 is connected to the first reaction chamber 2 at the forefront of the reaction chamber group 20 . The reaction channel 1 can be used for the mixing of single-component fluids, and can also be used for the mixing of multi-component fluids. The fluid enters each reaction chamber group 20 sequentially through the third fluid inlet 18, and per...

Embodiment 2

[0045] like Figure 4 , 5 , the difference from Example 1 is that the outside of the first reaction chamber 2 is connected in series with the second reaction chamber 9, the inner diameter of the second reaction chamber 9 is smaller than the inner diameter of the first reaction chamber 2, and the second reaction chamber 9 is provided with a second fluid inlet 10 With the second fluid outlet 11, the first reaction chamber 2 and the second reaction chamber 9 are connected end to end, the first fluid outlet 4 is facing the second fluid inlet 10, the second fluid outlet 11 is facing the first fluid inlet 3, and the second A second sub-fluid 12 is installed in the reaction chamber 9 , and the second sub-fluid 12 bends toward the second fluid inlet 10 . The second reaction chamber 9 is connected in series outside the first reaction chamber 2, the fluid accelerated by the first reaction chamber 2 enters the second reaction chamber 9, the fluid is accelerated again, and the fluid form...

Embodiment 3

[0047] like Figure 6 , different from Embodiment 1, two turbulent bodies are also provided in the first reaction chamber 2, which are respectively the first turbulent body 13 and the second turbulent body 14, and the first turbulent body 13 and the second turbulent body 14 are respectively in The second protrusion 7 and the third protrusion 8 are on the extension line of the bending direction.

Abstract

The invention discloses a micro-reactor, which is provided with a reaction channel, wherein the reaction channel has a plurality of first reaction chambers, the first reaction chamber is provided withfirst fluid inlets and a first fluid outlet, a first fluid dividing body is arranged in the first reaction chamber, and is provided with three projections of a first projection, a second projection and a third projection, the first projection, the second projection and the third projection are respectively positioned at the apex positions of a triangle, the first fluid outlet is opposite to the first projection, and the first fluid inlets are positioned in a region between the second projection and the third projection. According to the present invention, the micro-reactor can be used for thepassing through of solid particles having fluidity, can be used for multiphase reactions containing solid particles, and has the expanded application field.

Description

technical field [0001] The invention relates to the technical field of reaction equipment, in particular to a microreactor. Background technique [0002] A microreactor, namely a microchannel reactor, is a three-dimensional structural element that can be used for chemical reactions, physical and biological processes, manufactured with the help of special micromachining techniques and solid substrates. 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 refer to the small output of the microreactor equipment products, but means that the fluid channels are at the micron level, and the microreactor contains millions of Tens of millions of microchannels and therefore high throughputs are also achieved. [0004] The size of the microreactor is much smaller than that of th...
