Problems solved by technology

Once this happens, the velocity of fluid through that pore is drastically reduced, making further clogging more likely
Therefore, the microporous structure mixer often has high requirements on the cleanliness of the material, which limits its promotion and use

Abstract

The invention discloses a micro-structured mixer, which belongs to the technical field of chemical and chemical engineering. The micro-structured mixer is formed by stacking a first interface board, a first fluid distributing plate, a fluid mixing plate and a second interface board in sequence, wherein the first interface board is provided thereon with a first fluid inlet pipe and a first fluid buffer chamber, the first fluid distributing plate is provided thereon with at least one through slot, the fluid mixing plate is provided thereon with at least one through slot, the second interface board is provided thereon with a second fluid inlet pipe, a second fluid buffer chamber, a mixed fluid buffer chamber and a mixed fluid outlet pipe, when the number of the through slots arranged on the first fluid distributing plate is larger than one, the arranged through slots are parallel through slots, when the number of the through slots arranged on the fluid mixing plate is larger than one, the arranged through slots are parallel through slots. The treatment capacity of unit volume of the micro-structured mixer is larger, the micro-structured mixer is easy to store and enlarge, has low requirement for material cleanliness, and can be used in chemical, chemical engineering, petrochemical, medicine and food industries.

Description

technical field [0001] The invention belongs to the technical field of chemistry and chemical engineering, and in particular relates to fluid micro-mixing technology and equipment, which can be used in the mixing or reaction process between different fluids. In particular, it relates to a microstructure mixer. Background technique [0002] Traditional chemical reactors or mixers mainly use stirring to mix. Although the principle of this mixing method is simple, because the mixing scale in the equipment is at the millimeter level or even larger, the mixing efficiency is low and the energy consumption of the mixing process is low. Big question. Although tower-type, tubular-type reactors or mixers in the traditional sense have their own characteristics relative to full-mixing tanks, they also have low mixing efficiency because they are also in the range of millimeter-scale mixing with stirring equipment. The problem. At the same time, because these devices adopt the method o...
