Micro-contact mixer

Abstract

The invention relates to a high performance double multiple thin layer micro-contact mixer used for rapid mix, mass transfer and reaction of fluids in the chemical process, which belongs to the field of reaction and separation devices of chemistry and chemical engineering. The micro-contact mixer is formed by inserting an upper cavity chamber and a lower cavity chamber into an integral shell or by lapping closely connected shell components; a fluid inlet pipe of material A and a distribution chamber are communicated with a fluid parallel channel of material A; a fluid inlet pipe of material B and a distribution chamber are communicated with a fluid parallel channel of material B, thus forming the lower cavity chamber; a fluid mixing chamber and a mixed fluid outlet pipe are communicated to form the upper cavity chamber; two fluids enter the mixer from the inlet pipe through the distribution chamber respectively to make multiple thin layer contact in the fluid mixing chamber to realize rapid mix, mass transfer and reaction. The micro-contact mixer has the advantages of high mass transfer efficiency, high operational elasticity, uneasy blocking, easy processing and manufacturing and has good prospects in mixing and reaction fields such as the chemistry, chemical engineering, petrol-chemical industry, medicine and food.

Description

technical field [0001] The invention belongs to chemical reaction and separation devices, in particular to a high-performance, double-continuous multi-thin-layer micro-contact mixer for rapid mixing, mass transfer and reaction of fluids in chemical processes. Background technique [0002] In many fields such as chemistry, chemical industry, petrochemical, pharmaceutical and food, especially the reaction and separation process of chemical industry, it is necessary to carry out the mixing and reaction between two or more strands of materials, and the mixing performance has a very important influence on the reaction process. Commonly used mixing equipment includes mixing tanks and static mixers, etc. The former has a large volume and a longer residence time, while the latter has insufficient mixing, and neither of them can effectively strengthen and control microscopic mixing. In recent years, with the continuous development of micro-device processing technology, researchers ha...
