Problems solved by technology

[0007] Although the above research has alleviated the problem of microchannel blockage to a certain extent, it is difficult to ensure that micro-nano particle materials are not deposited on the microchannel wall, and long-term use will still cause microchannel blockage, and because most of the microchannels are in airtight space, and it cannot be cleaned later
And for exothermic reactions, the heat generated cannot be dissipated in time, which may cause local overheating of the device and damage the device and affect product quality
At the same time, the complexity and high cost of the fabrication of stacked microreactors further limit the application of microreactors in the preparation of micro-nanoparticle materials.

Embodiment 1

[0046] Such as Figure 1a-1c Shown are an exploded exploded view and an assembly view of a cylindrical non-stacked microreactor device with a cooling system according to a preferred embodiment of the present invention, which includes a cylinder 13 with microchannels a1, b1, and c1 engraved on the surface. (See Figure 2a , 2b ), the cylindrical body 13 covers the outer shell 12, and the inner surface of the outer shell 12 is provided with inlet A1, B1, C1 and outlet D1 channels connected with the microchannels a1, b1, and c1 on the outer surface of the cylinder 13 (see details Figure 3a , 3b ), an upper cover 11 and a lower cover 14 are arranged on the outer shell 12 to seal the cylinder 13 provided with the microchannels a1, b1, and c1 to ensure that the liquid in the microchannels a1, b1, and c1 will not leak, and The upper cover 11 and the lower cover 14 are connected with the outer casing 12 in a detachable connection mode; at the same time, a cooling system is provided in t...

Embodiment 2

[0056] Such as Figure 4a-4d Shown is an exploded exploded view and assembly view of a cone non-stacked microreactor device with a cooling system according to another preferred embodiment of the present invention, which includes a cone with microchannels a2, b2, and c2 engraved on the surface 23 (see Figure 5a , 5b ), the cone 23 covers the outer shell 22, and the inner surface of the outer shell 22 is provided with inlet A2, B2, C2 and outlet D2 channels connected to the microchannels a2, b2, and c2 on the outer surface of the cone 23 (see Figure 6a , 6b ), a fastening pressure cover 21 is provided on the outer shell 22, and the pressure on the cone 23 by the fastening pressure cover 21 promotes the self-sealing effect of the cone 23 to ensure the liquid in the microchannels a2, b2, and c2 No leakage, the fastening press cover 21 and the outer shell 22 are connected in a detachable manner; at the same time, a cooling system is provided in the cone 23 and the outer shell 22. T...

Embodiment 3

[0066] Referring to Example 1, in this example, only a cooling system is provided in the cylinder 13. The cooling system adopts a partition type cooling hole, that is, a blind hole 5 is punched on the cylinder 13 on the side of the reaction product solution channel c1 along its axis. , A connecting groove 6 is provided between the hole 5 and the hole 5, and the partition 7 is inserted in the hole 5. The cooling water flows in from one side of the partition 7 and flows out from the other side, and then enters the adjacent holes 5 through the connecting groove 6 in turn; thereby effectively preventing Blockage of the micro-channels of the micro-reactor and local overheating of the micro-reactor device. Other technical features are similar to those in Embodiment 1, and are easy to understand for those skilled in the art, and will not be repeated.

Abstract

The invention discloses a non-laminated structure micro-reactor with a cooling system. The micro-reactor comprises a main body part with a micro-channel engraved in the surface. An outer housing sleeves the main body part. the inner surface of the outer housing is equipped with an inlet channel and an outlet channel communicated with a micro-channel in the outer surface of the main body part. A sealing part is arranged on the outer housing, the sealing part seals the main body part with the micro-channel to ensure a situation that a liquid in the micro-channel cannot be leaked, and the sealing part and the outer housing are connected in a detachable connection manner. A cooling system is arranged in the main body part and / or the outer housing. Dismounting cleaning and system cooling can be carried out, and blocking of the micro-channel of the micro-reactor and local overheating of the micro-reactor device are prevented effectively. The structure is simple and the cost is low.

Description

Technical field [0001] The invention relates to a micro-reactor device, in particular to a non-stacked structure micro-reactor device with a cooling system. Background technique [0002] In recent years, the microreactor has made many achievements in the research of preparing micro-nano granular materials, and has great potential and application prospects. Compared with conventional methods for synthesizing micro-nano granular materials, the synthesis of micro-nano granular materials in a microreactor is easy to control and scale up. Micro-nano with different shapes, particle sizes and particle size distributions can be obtained by conveniently and accurately adjusting the reaction parameters. Granular material. In addition, due to the characteristics of the micro-nano particulate materials prepared by the microreactor, the microreactor has a broad application prospect in the preparation of micro-nano particulate materials with high tap density and uniform particle size.
