Problems solved by technology

Method 1 will cause many system control points, high precision requirements, and high production costs in industrial operation, and the gains outweigh the losses
Method 2 has the problem of "amplification effect", that is, the distance between the position of each functional unit and the feed point is not equal, and the performance of the fluid entering each functional unit is not equal, which affects the overall mixing and reaction effect
Under the high-efficiency reaction of the microchannel reactor, especially in the case of strong exothermic reaction and rapid reaction, it is difficult to release a large amount of heat from the reaction system in time, causing great safety hazards and cannot be put into normal production

Embodiment 1

[0028] The basic structure and connection relationship are the same as the above attached figure 1 , 3 shown. Specifically, the arcs of the microchannel reaction lines 11 on the horizontal cross-sectional circumference of the inner shell 13 are 15°; the groove depth of the microchannel reaction line 11 is 0.5 mm, and the groove width is 0.5 mm. In this situation, it can adapt to the industrialized safe production of most dangerous chemical reactions such as strong exothermic and fast.

Embodiment 2

[0030] The basic structure and connection relationship are the same as the above attached figure 1 , 3 shown. Specifically, the arc of the microchannel reaction line 11 on the horizontal cross-sectional circumference of the inner housing 13 is 45°; the groove depth of the reaction line of the microchannel reaction line 11 is 0.3mm, and the groove width is 0.3mm. In this situation, it is suitable for industrialized safe production of more intense and faster exothermic chemical reactions.

Embodiment 3

[0032] The basic structure and connection relationship are the same as the above attached figure 1 , 3 shown. Specifically, the arcs of the microchannel reaction lines 11 on the horizontal cross-sectional circumference of the inner shell 13 are 90°; the groove depth of the microchannel reaction line 11 is 0.2 mm, and the groove width is 0.2 mm. Under this situation, the industrial production of dangerous chemical reactions with more intense heat release and faster control is more accurate and the safety guarantee is the strongest.

Abstract

The invention discloses a micro-channel reactor capable of realizing large-scale production and belongs to the technical field of chemical micro-structure reaction devices. The micro-channel reactor capable of realizing the large-scale production is characterized in that a reactor body comprises an outer shell (10) and an inner shell (13) in an interference fit mode, at least one micro-channel reaction line (11) is arranged between the inner shell (13) and the outer shell (10), an inner secrete room and an outer secrete room are arranged at the top of the reactor body, the inner secrete room is an inner raw material gathering cabin (5), the outer secrete room is an outer raw material gathering cabin (4), and a first raw material inlet (1) is opened in the center of the inner raw material gathering cabin (5); a finished product gathering cabin (12) is arranged at the bottom of the reactor body; the micro-channel reaction line (11) is communicated with the raw material gathering cabin (4) and the finished product gathering cabin (12), and a cooling system is respectively arranged in and outside the reactor body. The micro-channel reactor capable of realizing the large-scale production eliminates the amplification effect of the micro-channel reactor and enables the total reacting dose to be increased while guaranteeing the micro-scale of each reaction line so that the industrialized mass production can be achieved.

Description

technical field [0001] The invention discloses a microchannel reactor for realizing large-scale production, which belongs to the technical field of chemical and chemical microstructure reaction devices. Background technique [0002] In the early 1990s, the need for sustainable and high-tech development promoted the research of micro-chemical technology. The main research object is micro-channels with characteristic scales at the micron level. Due to the miniaturization of scales, the heat transfer of chemical fluids in micro-channels Compared with the conventional system, the mass transfer performance has been greatly improved, that is, the miniaturization of the system can realize the goal of strengthening the chemical process. [0003] In essence, the microchannel reactor is a continuous flow tubular reactor, and most of the current microchannel reactors are small reactors of laboratory experiment level. The traditional microchannel reactor is basically a "flat plate" str...
