Embodiment 1

[0070] Such as Figure 2-4 , as shown in 6-8, the present embodiment provides a microchannel reaction assembly, including stacked settings:

[0071] The first layer of passages is provided with a number of branch passages 44. The branch passages 44 are arranged in rows, and at least one row is arranged. Along the arrangement direction, the branch points of the branch passages 44 are set close to the first direction. At least two branches formed by points are disposed adjacent to a second direction opposite to said first direction;

[0072] The second layer of passages is provided with several confluence passages 64 on it, and the confluence passages 64 are arranged in rows, and at least one row is provided. The confluence of the point collection is arranged close to the first direction;

[0073] The communication channel is arranged between the first-layer channel and the second-layer channel, and at least one column of serial channels is arranged on it, and each column of t...

Embodiment 2

[0108] Such as Figure 1-9 As shown, this embodiment provides a microchannel reactor with the microchannel reaction assembly described in Example 1.

[0109] In the microchannel reactor provided in this embodiment, at least one side of the microchannel reaction component is stacked with a heat exchange unit, which can dissipate heat from the microchannel reaction component. The heat exchange unit includes two stacked heat exchange plates, a heat exchange medium channel is arranged between the two heat exchange plates, and a heat exchange medium inlet and a heat exchange medium outlet communicate with the heat exchange medium channel.

[0110] The microchannel reactor provided in this embodiment also includes: a heat exchange medium inlet and outlet plate 7, on which an initial heat exchange medium inlet 71 communicated with the heat exchange medium inlet, and an initial heat exchange medium inlet 71 communicated with the heat exchange medium outlet The final heat exchange med...

Embodiment 3

[0116] This embodiment provides a microchannel reaction assembly, which is different from the microchannel reaction assembly provided in Example 1 in that the microchannel reaction assembly is formed by processing a single plate, and the branch channel, confluence channel and serial flow The channels are all arranged on a single plate, which can reduce the material cost of the microchannel reaction components.

Abstract

The invention relates to the technical field of reaction equipment in the fields of chemical industry, pharmacy and the like, in particular to a micro-channel reaction assembly and a micro-channel reactor. The micro-channel reaction assembly comprises: branch channels which are arranged in a first layer and are used for dividing a reaction medium; a confluence channel which is arranged in the second layer and is used for confluence of the reaction medium; communicating flow channels which are arranged between the first layer and the second layer and are communicated with the branch channel andthe convergence channel. The reaction medium is divided through the branch channels and flows to the convergence channel on the second reaction plate in series through the communicating flow channelson the communicating separation plate for confluence, and sequentially reciprocates for a plurality of cycles for a reaction on the reaction medium, so that the mixing among the media can be effectively intensified. The micro-channel reaction assembly can be compatible with reactions of granular solids with a certain diameter, so that the heat transfer efficiency is higher, the mixing effect between fluids is effectively intensified, the reaction time is shortened, and the product yield is increased.

Description

technical field [0001] The invention relates to the technical field of reaction equipment in the fields of chemical industry, pharmacy and the like, in particular to a microchannel reaction component and a microchannel reactor. Background technique [0002] In the field of micro-reaction systems, after the materials transported by the volumetric conveying equipment enter the reactor, the mass transfer and heat transfer of the raw materials fail to reach the required level, which will inevitably increase the residence time of the materials in the reactor and affect the reaction. efficiency. And some reactions involve solid particles with a certain concentration and diameter. If the structure of the microreactor channel is not compatible with certain solid particles, the selectivity of the reaction device will be compromised. Therefore, it is necessary to have a microchannel reactor with good mass transfer and heat transfer effect and compatible with a certain concentration a...
