Problems solved by technology

[0003] Traditional microchannel reactors are basically made of metal materials. Although they have been qualitatively improved compared with reactor technology, they still cannot meet some special application fields, such as reactions with high corrosion, high erosion and high thermal conductivity requirements.

Abstract

The invention discloses a continuous type multilevel microchannel reaction device, and belongs to the technical field of reactors. The continuous type multilevel microchannel reaction device providedby the invention solves problems that conventional equipment is low in heat conductivity, low in corrosion resistance and the like. The continuous type multilevel microchannel reaction device comprises a first-level reaction system and an mth-level reaction system which are connected through a pipeline; m is a positive integer greater than 1; the first-level reaction system consists of a microchannel reactor and a mixing tank; the mth-level reaction system consists of a microchannel reactor, a mixing tank and a buffer tank; the buffer tank is connected with the mixing tank and the microchannelreactor respectively. The continuous type multilevel microchannel reaction device can be applied to reactions having high-corrosion, high-scouring and high-heat-conduction requirements.

Description

technical field [0001] The invention relates to a continuous multi-level microchannel reaction device, which belongs to the technical field of reactors. Background technique [0002] A microchannel reactor is a microreactor with a characteristic size between 10 and 300 microns (or 1000 microns) manufactured using precision machining technology. The overall size of the reaction equipment is small or the output of the product is small. [0003] Traditional microchannel reactors are basically made of metal materials. Although they have been qualitatively improved compared to reactor technology, they still cannot meet certain special application fields, such as reactions with high corrosion, high erosion and high thermal conductivity requirements. The pressureless silicon carbide material is the material with the strongest comprehensive performance among all ceramic products. It has extremely strong corrosion resistance, ultra-high thermal conductivity, extremely high hardness,...
