Specific embodiment
The embodiments of the present invention is described with reference to the accompanying drawings, wherein the identical appended drawing reference table of identical component
Show.In the absence of conflict, the technical characteristic in following embodiment and embodiment can be combined with each other.
The utility model is described by taking chloromethanes and salicylic mixing as an example, but the utility model is not limited to
This.
As shown in Figure 1, the reaction system of the utility model includes: microreactor 9, for the mixing of two kinds of fluids, therefore
Two branches are connected, one of branch includes: the first preserving jar 1, the first filter device 2, first pump 3 and First Heat Exchanger 4.
First preserving jar 1 is stored with chloromethanes, and chloromethanes is filtered by the first filter device 2, enters the first heat exchange after 3 pressurization of the first pump
Device 4 heats.Another branch includes: the second preserving jar 5, the second filter device 6, second pump 7 and the second heat exchanger 8.Second storage
Object tank 5 is stored with salicylic acid, and salicylic acid is filtered by the second filter device 6, enters the second heat exchanger 8 after 7 pressurization of the second pump and adds
Heat.
Microreactor 9 can be made of 3D printing technique, can be divided into 3 layers: upper layer, lower layer and intermediate mixed layer.Fig. 2 is shown
The sectional views of the upper and lower of microreactor 9.Fig. 3 shows that the sectional view of the intermediate mixed layer of microreactor 9 (is beaten in figure
The part of oblique line is the ontology solid section of microreactor 9, and starlike fill part is heat exchanging fluid).
As shown in Fig. 2, microreactor 9 includes shell 91, upper layer is heat exchanging fluid entry level, and lower layer is heat exchanging fluid outlet
Layer.In the upper and lower, heat transfer fluid channels 92 are provided with, to inject by heat exchanging fluid, to guarantee to mix in microreactor
When good temperature control function.In order to increase heat transfer effect, the heat transfer fluid channels 92 being arranged in the upper and lower are in
Between the reacting fluid channel 93 of mixed layer be vertical (parallel paper direction and vertical paper direction), two fluids will not be handed over
It changes.Intermediate mixed layer forms curved reaction as shown in figure 3, the tube wall of heat transfer fluid channels 92 is divided into multiple portions
Fluid channel 93, reacting fluid channel 93 and heat transfer fluid channels 92 input reacting fluid and heat exchanging fluid respectively.Middle layer is left
Top is two entrances H1, H2 of two fluids to be mixed, and the fluid after two liquefaction is first injected in this section, next
Just it is mixed in caliber continually changing waveform reacting fluid channel 93.
Preferably, it is done so in the place setting wedge block 94 of 93 maximum curvature of reacting fluid channel to hinder to flow
Purpose is to change flow velocity, reinforces disturbance, promotes mixing.
Found out in heat transfer process by the setting of heat exchange pipeline, flowing each segment fluid flow can by least from
The heat of the heat exchanging fluid in one direction exchanges, and heat transfer effect is very good and stablizes.The outlet C1 in last channel is in the knot
The upper right side of structure mixed layer, i.e. mixing liquid are entered by mixed layer, mixed layer outflow, and heat exchanging fluid is entered by top layer, most
Lower layer's outflow, two fluids are simultaneously not directly contacted with.
By taking chloromethanes and salicylic acid as an example, the first preserving jar 1 for accommodating chloromethanes is inversion state, this is in order to ensure stream
Chloromethanes out is liquid.Chloromethanes liquid is added after crossing the first filter device 2 and going out contaminant filter therein by pump after flowing out
It is pressed into heat exchanger, then flow in microreactor 9.The salicylic acid that salicylic acid channel flows into is same, with liquefied chloromethanes one
It is same to enter microreactor.Liquefied chloromethanes enters from chloromethanes entrance, and salicylic acid enters from salicylic acid entrance, and the two is in diameter
It is mixed in the microchannel constantly converted.The transformation of microchannel diameter is to strengthen mixed effect, in channel to reinforce disturbing
Wedge block be also this effect.In order to guarantee reaction temperature, has heat exchanging fluid and enter from heat exchange pipeline and from heat exchange pipeline
Outflow, heat exchange pipeline is different with hybrid channel, therefore only heat exchanges and do not have between heat exchanging fluid and reacting fluid
Mass exchange.Furthermore it is possible to adjust the number of modules in reactor, as needed to achieve the purpose that adjust the residence time.
After the reaction in microreactor 9 terminates, product by the outlet of hybrid channel flow out through pressure reducing valve 13 into
Enter separator 10, the gaseous chloromethanes in reactant is allowed to be separated with product by pressure, it is final to reach acquisition
The purpose of product.Meanwhile the chloromethanes isolated can also make it return liquid again by the cooling of third heat exchanger 11, via
Third pump 12 continues to put into the use of next round.
By the utility model, the existing step can be chemically reacted (liquid chloromethanes adds 25% salicylic acid, 22MPa,
80 DEG C) needed for the 10h reaction time foreshorten to 240s, while yield is further promoted to 98%, salicylic conversion ratio is
100%, and required place compare before reaction kettle volume can be contracted to the size of a desktop.Due to reaction rate pole
It is big to improve, therefore existing process scale production can be easily reached.
Embodiment described above, only the utility model more preferably specific embodiment, those skilled in the art
The usual variations and alternatives carried out within the scope of technical solutions of the utility model should all be included in the protection scope of the utility model
It is interior.
