Micro reactor with bamboo joint-shaped micro structure

Abstract

The invention discloses a microreactor with a bamboo-shaped microstructure, and relates to the technical field of microreactors. Including material inlet pipe, module, material outlet pipe, heat exchanger inlet pipe and heat exchanger outlet pipe, modules and modules are alternately stacked between relatively parallel inlet pipes and outlet pipes, and the modules are separated by membrane blocks The connecting pipe is connected. The module is a sandwich structure made of metal materials, the outer layer is used for the circulation of the heat transfer fluid, and the inner layer is used for the mixing and chemical reaction of the reactive fluid, thus realizing the integration of mixing and heat transfer. This structure will not affect the heat transfer performance when maintaining a certain flux of fluid; and the fluid provides excellent flow control in the microchannel module, which can operate at minus 100°C to minus 350°C, and the maximum pressure can reach 10 megabytes Pa, and greatly improve production efficiency, reaction speed, safety, etc., with high strength and low density, good mechanical properties, good toughness and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of microreactors, in particular to a microreactor with a bamboo-shaped microstructure for microchemical reactions. Background technique [0002] Microchannel reactor is essentially a continuous flow tube reactor. Compared with conventional reactors, its internal channel diameter is very small, usually 10-500 μm, but it is this structural characteristic that makes it extremely The large specific surface area can even reach several hundred times or even tens of thousands of times the specific surface area of ​​conventional reactors, and thus generate great heat exchange efficiency and mass transfer efficiency, so that the reaction temperature can be precisely controlled to ensure instant mixing of the reaction materials. Helps improve chemical reaction yield, selectivity, safety, and product quality. Compared with conventional macro-reactors, micro-channel reactors have the following advantages: ① Channel geo...
