Problems solved by technology

However, from the specific structure to the actual use and performance, it is quite different.
[0007] No matter what kind of structure is used, there are very few examples of continuous industrial production of large-flow and large-tonnage products using the principle of micro-channels at home and abroad. The manufacturing cost is high, and most of them cannot adapt to the working conditions of high temperature, high pressure, and fluid containing solid crystals and powder components, and it is impossible to double the output through simple parallel connection of multiple machines
Therefore, microreactors are expensive and complex in structure, and it is currently difficult to realize industrialization of large throughput and large tonnage.

Abstract

The invention discloses a multifunctional slit fluid micro-channel reaction / mixing / heat exchanger unit. The multifunctional slit fluid micro-channel reaction / mixing / heat exchanger unit comprises a first reaction part, a second reaction part and a torsion connecting part, the cross section of the first reaction part and the cross section of the second reaction part are both flat type slit structures, the first reaction part and the second reaction part are mutually twisted, a torsion connecting part is formed at the joint of the first reaction part and the second reaction part, and the torsionconnecting part is in a triangular horn-shaped smooth cavity in the torsion process; and the number of the slits is one or more. When the fluid passes through the first reaction part, the fluid molecules which are required to participate of the reaction / mixing / heat exchange are forcibly extruded and combined in the slits, and the fluid molecules enter the torsion connecting part after passing through the first reaction part, the fluid is released, mixed, twisted, re-extruded and enters the second reaction part. The repeated mixing effect is better than that of a single-flow channel similar tothat of a horizontal pushing flow, the manufacturing cost and the processing difficulty of the core structure of the micro-reactor can be greatly reduced, and the micro-reactor is applied to the fluidproduction process of the small sized, the medium-sized and even-ten-grade.

Description

technical field [0001] The present invention relates to a kind of multifunctional narrow-type equipment used in petrochemical, fine chemical, pharmaceutical preparation, food and beverage and other industrial fields, which can replace the existing traditional kettle type, container type chemical reaction, homogeneous mixing and physical heat exchange equipment. A slot-type fluid microchannel reaction mixing heat exchange unit, the present invention also provides a method for using the unit reaction components in parallel or in series. Background technique [0002] In industrial manufacturing fields such as petrochemicals, fine chemicals, pharmaceutical preparations, food and beverages, physical mixing or chemical reactions of homogeneous and heterogeneous fluids are often used, and such physical mixing and chemical reactions are usually accompanied by strong Temperature changes (mostly instantaneous heat release) and poor control will cause catastrophic consequences such as ...
