Intelligent industrialized micro-channel flow reactor

Abstract

The invention relates to the technical field of reaction devices for petrochemical engineering, fine chemistry, pharmacy, plastic, synthetic rubber, coating, food processing and the like, in particular to an intelligent industrialized micro-channel flow reactor which greatly improves safety and environment protection performance, greatly saves energy and greatly improves production efficiency. The intelligent industrialized micro-channel flow reactor comprises a shell, a raw material inlet, a product outlet, an end socket and a reaction pipe, and is characterized in that a three-dimensional micro-channel assembly is closely inserted in the reaction pipe, and a plurality of continuous-penetrating micro-channels in the scale of microns or millimeters are formed between the outer surface of the three-dimensional micro-channel assembly and the inner wall face of the reaction pipe. The mass transfer resistance between reaction raw materials is greatly reduced, reaction heat can be rapidly conducted in time, reaction time is shortened, back-mixing and side reaction are reduced, solvent consumption is lowered or eliminated, safety and reliability are high, energy conservation and emission reduction can be greatly achieved, yield is increased, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of reaction equipment used in petrochemical industry, fine chemistry, pharmacy, plastics, synthetic rubber, paint, food processing and the like. More specifically, it involves an intelligent industrialized microchannel that can partially replace traditional batch production reactors and reactors, greatly reduce land, workshop area and equipment investment, greatly improve safety and environmental performance, greatly save energy, and greatly improve production efficiency continuous reactor. Background technique [0002] In petrochemical, fine chemical, pharmaceutical, food processing and other production fields, for liquid / liquid, gas / liquid, gas / solid / liquid homogeneous, heterogeneous normal pressure, high pressure reaction, polymerization reaction, it is usually used Traditional stirring and reaction kettle for reaction. However, due to the innate structure of the agitator and the reactor, the mass trans...

AI Technical Summary

Problems solved by technology

However, because it is carved with special glass, special ceramics or stainless steel, the processing technology is relatively complicated, the price is extremely expensive, and the flow rate that is difficult to increase due to the limitation of the principle, and the limitation of the connection material and structure also restrict it. Popularization and application of high-pressure and medium-scale industrial production

[0008] There are other forms of various microchannel reactors at home and abroad, but mature industrial microchannel reactors that can be scaled up to thousands of tons / year flow rate are extremely rare
