Embodiment 1

[0054] Please also refer to figure 1 and image 3 , the micro-reaction channel provided by the present invention is now described. The micro-reaction channel is arranged on the substrate 31, one side of the substrate 31 is formed with at least two first microchannel units 311 arranged in sequence, and the other side of the substrate 31 is formed with at least two microchannel units arranged in sequence. The second microchannel unit 312, the first microchannel unit 311 and the second microchannel unit 312 are arranged alternately, and the end of the first microchannel unit 311 and the head end of the second microchannel unit 312 The end of the second microchannel unit 312 communicates with the head end of the next first microchannel unit 311 .

[0055] Compared with the prior art, the micro-reaction channel provided by the present invention is composed of several first micro-channel units 311 and second micro-channel units 312 connected in sequence, and the first micro-channe...

Embodiment 2

[0062] see figure 2 and image 3 , as another specific embodiment of the micro-reaction channel provided by the present invention, the difference between this embodiment and embodiment 1 is that the shapes of the first micro-channel unit 311 and the second micro-channel unit 312 are different. In this embodiment, the shapes and directions of the first microchannel unit 311 and the second microchannel unit 312 are consistent or the first microchannel unit 311 and the second microchannel unit 312 are arranged symmetrically, and the first microchannel unit 311 and the second microchannel unit 312 are arranged symmetrically. The second microchannel units 312 are arranged at intervals, the shapes of the first microchannel unit 311 and the second microchannel unit 312 are both cardioid-like, and arc-shaped channels are connected to the bottom ends of the cardioid-like shapes.

[0063] Specifically, the first microchannel unit 311 includes a third main channel 3113, a third branch ...

Embodiment 3

[0072] see Figure 4 to Figure 6 , Figure 10 to Figure 12 as well as Figure 16 , the present invention also provides a reaction substrate 3, and the reaction substrate 3 provided by the present invention will now be described. The reaction substrate 3 includes a substrate 31 and a cover plate 32, and the two sides of the substrate 31 are respectively provided with at least two groups of micro-reaction channels as described in embodiment 1 or embodiment 2 and connecting two adjacent micro-reaction channels. The connecting channel 314 ; the cover plates 32 are located on opposite sides of the substrate 31 , and the two cover plates 32 are respectively covered on the first micro-channel unit 311 and the second micro-channel unit 312 .

[0073] The reaction substrate 3 provided by the present invention is directly processed and grooved on the substrate 31 to respectively form the first microchannel unit 311, the second microchannel unit 312 and the connecting channel 314, and ...

Abstract

The invention provides a microreaction channel, a reaction substrate and a microchannel reactor. The microreaction channel comprises a first microchannel unit and a second microchannel unit, the firstmicrochannel unit and the second microchannel unit are arranged on the two sides of the substrate respectively, the tail end of the first microchannel unit is communicated with the head end of the second microchannel unit, and the tail end of the second microchannel unit is communicated with the head end of the next first microchannel unit. The microreaction channel provided by the invention is characterized in that the first microchannel unit and the second microchannel unit which are respectively positioned on two sides of the substrate are sequentially connected end to end; media to be mixed roll over and flow on the two sides of the substrate; besides collision on a single plane, the media also have an up-and-down rolling flow trend, the turbulence effect is enhanced, the problem of complex processing caused by different widths of the whole reaction channel is avoided, the media with certain concentrations and particle solid media with a certain diameter have better reaction and flow effects, the structure is simple, and the production and the processing are convenient.

Description

technical field [0001] The invention relates to the technical fields of chemical industry and pharmacy, in particular to a micro-reaction channel, a reaction substrate and a micro-channel reactor. Background technique [0002] At present, energy and fresh water resources are continuously depleted, but with the rapid development of industry, the demand for energy and fresh water resources is still increasing. Therefore, it is increasingly important to increase the efficiency of product synthesis in fields such as chemical and pharmaceutical industries and to continuously change productivity. The production scheme implemented by using microchannel reactors can obtain higher product yields and fewer by-products using less raw materials, and the production method is safer and energy-saving, which can meet the production requirements. [0003] The so-called microreactor refers to at least partially adopting microreaction technology or ultra-precision processing technology in man...
