[0014] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings. The same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. Unless otherwise specified, the raw materials and equipment used are commercially available or commonly used in the art. The methods in the embodiments, unless otherwise specified, are conventional methods in the art. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0015] A liquid-phase medium enhanced reaction device for a microreactor, the device includes a cylindrical shell 1, a plurality of micro chambers 4 arranged in sequence therein, the micro chamber 4 is cylindrical, the outer diameter of the micro chamber 4 is equal to the inner diameter of the shell 1, the micro chambers 4 are connected end to end in sequence, adjacent micro chambers 4 are supported by a spacer 5 to maintain the spacing, each cavity has an independent liquid inlet 44 and a liquid outlet 45, an inlet 2 and an outlet 3 are respectively provided at both ends of the shell 1, the inlet 2 and the outlet 3 are respectively connected to the liquid inlet 44 and the liquid outlet 45 at the end of the whole; the micro chamber 4 includes a front cover 41 and a rear cover 42, the front cover 41 and the rear cover 42 are connected to each other, and the liquid inlet 44 and the outlet 45 at the end of the whole are respectively connected to each other. After the cover 42 is axially connected, a complete cavity is formed inside. A liquid-facing plate 43 is provided in the micro-cavity 4. The liquid-facing plate 43 is in the shape of a circular plate. The liquid-facing plate 43 faces the liquid inlet 44 and faces the liquid outlet 45. A plurality of grooves 1 are provided on the front of the liquid-facing plate 43, and a plurality of grooves 2 are provided on the inner wall of the front cover 41. The grooves 1 and 2 are staggered in succession to form a large number of fluid channels that meander along the radial direction as a whole, forming a multiple micro-reactor structure. When the medium passes through the fluid channel, it needs to go back and forth between the grooves 1 and 2. The denser the grooves 1 and 2, the better the reaction enhancement effect when the medium passes through the fluid channel. The liquid-facing plate 43 is bolted to the front cover 41 ( Figure 2 ), the uneven surface of the liquid-facing plate 43 fits into the uneven inner wall of the front cover 41.
[0016] The micro cavity 4 in the housing 1 can be flexibly adjusted according to work needs, and the adjustment content is not limited to the number of cavities set, the cavity size in the cavity, the caliber density of groove 1 and groove 2 in the cavity, etc.
[0017] A liquid-phase medium enhanced reaction method for a microreactor, using the liquid-phase medium enhanced reaction device for the microreactor, further comprising the following: The medium enters the device from the inlet 2, passes through each micro-cavity 4 and the intervals between cavities in turn, and is discharged from the outlet 3; After the medium enters the micro-cavity 4 from the liquid inlet 44, it first collides with the liquid-receiving plate 43 and disperses. Then, after flowing through the fluid channel, it converges again on the back of the liquid-receiving plate 43 and flows out from the liquid outlet 45. During the process of passing through the micro-cavity 4, the medium experiences rapid alternation of high and low pressures, especially when passing through the fluid channel, which can cause the most violent reaction. The above process is repeated as the medium flows through each micro cavity 4 in sequence, achieving multiple continuous enhanced reactions; making the reaction more thorough and efficient, and if used for gas-liquid mixing, it will produce more delicate microbubbles.
[0018] In some embodiments, the front of the liquid-facing plate 43 is concentrically provided with multiple layers of baffles 1, each layer with multiple arcs, and the inner wall of the front cover 41 is concentrically provided with multiple layers of baffles 2, each layer with multiple arcs, and baffles 1 and 2 are staggered to form a winding fluid channel.
[0019] The more layers of baffles 1 and 2 are provided, the more dramatic the direction change and pressure change of the medium when passing through the fluid channel, and the better the reaction effect.
[0020] In some embodiments, the position of the liquid-receiving plate 43 within the microchamber 4 is not fixed. The angle of the liquid-receiving plate 43 can be adjusted by loosening the bolts (the bolt holes in the front cover 41 are curved), then tightening the bolts to relock. By rotating the angle of the liquid-receiving plate 43, the shape and path of the fluid channel can be adjusted, thereby varying the degree of enhanced reaction. For example, rotating the liquid-receiving plate 43 narrows the intersecting connection between slots 1 and 2, resulting in more dramatic changes in the flow velocity of the medium flowing through, and thus a stronger enhanced reaction effect.
[0021] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the above embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
