Abstract

The invention discloses a tubular type double-annular channel double-sided heat-exchange large-flux microchannel reactor. The reactor is sheathed in a tube (2) through an isolating sleeve (3), a middle sleeve (4) is further sheathed in the isolating sleeve (3), two annular clearance microchannels are respectively formed between the isolating pipe (3) and the tube (2) and between the isolating pipe (3) and the middle sleeve (4), and the space of the annular clearances is 0.05-5mm. By adopting the tubular type annular microchannel, the section area of the microchannel is increased by orders of magnitude, the large-flux difficulty of the microchannel reactor can be solved, so that the microchannel reactor is widely applied in chemical industry, and the high-risk technology status of the currently chemical synthesis can be thoroughly changed, the safety can be greatly enhanced, and the environmental pollution can be effectively decreased.

Description

technical field [0001] The invention relates to a micro-reactor, in particular to a tube-and-tube double-annular channel double-sided heat exchange large-flux micro-channel reactor. Background technique [0002] Microreactors are a new type of reaction equipment, which originated in the 1990s. Specifically, microreactors generally refer to reaction equipment with microstructures manufactured using micromachining technology and precision machining technology. The fluid channel or dispersion scale in the device is on the order of microns. As a new type of reaction equipment, the form of microreactor has been continuously developed in recent years. Microstructure is the core of microreactor. Different types of microreactors have been produced according to the type of microstructure, such as microchannel reactor, capillary micro Reactor, falling film microreactor, multi-stream parallel flow microreactor, microwell array and membrane dispersed microreactor, and external field en...
