Microchannel continuous reactor

Abstract

The invention relates to the technical fields of reaction equipment used in petrochemical industry, fine chemistry, pharmacy, plastic, synthetic rubber, paint, food processing and the like, and particularly relates to a microchannel continuous reactor which can greatly improve safety and environmental protection performance, greatly save energy, and greatly increase production efficiency. The microchannel continuous reactor comprises a shell, a raw material inlet, a product outlet, a sealing head and a reaction tube, and is characterized in that a three-dimensional microchannel assembly is tightly inserted in the reaction tube; a plurality of um / mm-level micro-channels which are in a penetrating manner all the time are formed between the outer surface of the three-dimensional microchannel assembly and the inner wall surface of the reaction tube. The reactor can greatly reduce the mass transfer resistance among reaction materials, can quickly transfer reaction heat timely, shorten the reaction time, reduce the back mixing and side effects, and reduce or eliminate the use of solvents, is high in safety and reliability, and can greatly save energy, reduce emission, increase the yield and improve the production efficiency.

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 a microchannel continuous reaction 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 device. 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 transfer resistance is la...

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
