A microstructure mass transfer device

Abstract

The invention discloses a microstructure mass transfer device belonging to the general method field of chemistry; it includes a fluid distribution section, a fluid mixing section and a mixed fluid collection section closely connected in sequence, wherein the second fluid mixing section is guided by N pieces of mixed fluid The plate and N-1 fluid partition plates are stacked from top to bottom in a staggered manner; the middle of the mixed fluid deflector is provided with a fluid buffer chamber and a second fluid inlet channel, wherein the second fluid inlet channel is located in the fluid buffer One side of the chamber; the side of the fluid buffer chamber adjacent to the fluid partition plate is provided with an outlet, and a fluid dispersion medium is installed at the outlet of the fluid buffer chamber; a plurality of channel grooves are respectively opened on the upper and lower end surfaces of the fluid partition plate, and the channel grooves guide The incoming fluids diverge first and then join again. The flow channel of the present invention divides the first fluid flow channel into several millimeter-level micro-channels through two-stage and two-dimensional amplification, which helps to achieve efficient shear mixing and micron-level dispersion of continuous phase fluid and dispersed phase fluid .

Description

technical field [0001] The invention belongs to the technical field of general chemical methods, and specifically relates to a microstructure mass transfer device. Background technique [0002] With the advancement of technology, many equipment in the chemical production process have continuously strengthened the flow, heat transfer and mass transfer performance of the process through structural improvement. Among them, micro-chemical industry has become an important means of chemical process intensification. By reducing the mixing scale from the millimeter level of traditional equipment to the micron level, the specific surface area can be enlarged, the concentration gradient can be increased, and heat exchange and mixing can be significantly promoted in a short time. In the confined space provided by the microreactor, the heat transfer and mass transfer coefficients can be increased by 1-3 orders of magnitude compared with conventional equipment. At the same time, becaus...

Problems solved by technology

[0003] Based on the idea of ​​micro-chemical industry, miniaturized mixing and reaction equipment have emerged in an endless stream in recent years, but basically there are narrow and tortuous internal flow channels, which limit the further increase of fluid solid content and viscosity during the reaction or mixing process on the one hand, and on the other hand Part of the reaction or mixing space cannot fully exert its efficiency due to the existence of the dead zone
