The lower section for shunting the structure that liquidates is arranged on, more specifically design is that the flow-disturbing block is located under the opening of the flow deflector
Side, so allow for the structure that liquidates that shunts and complete the effect of liquidating and then acted on by the flow-disturbing of the turbulence structure, make
Fluid is sufficiently mixed.
Preferably, the V-shaped angle of sidewall shrink in the exit of second reaction chamber 200, makes second reaction chamber
The fluid of the outlet port of room 200, which is reduced, produces vortex, so as to preferably be mixed in exit；
Preferably, the opening angle β scopes at the V-type angle are 30-160 degree, preferably 60-120 degree, more preferably 90
Degree.
Preferably, the side wall 205 of at least partly described second reaction chamber is straight wall；Preferably, second reaction chamber
The side wall of the both sides of room is parallel.Side wall 205 makes institute using the parallel design of the side wall 205 of straight wall and second reaction chamber
When stating the reaction chamber of microreactor has multiple row setting, the space inside microreactor is more effectively utilized.
Embodiment 3
The present embodiment provides a kind of microreactor with multiple reaction channels, is set on the basis of above example
Meter.
Preferably, the reaction channel includes at least two to be arranged side by side, corresponding at least two reaction channel
Common chamber side wall between reaction chamber.As shown in figure 1, the microreactor that the present embodiment provides is arranged side by side for four passages.
Preferably, as shown in Fig. 2 being connected between adjacent reaction chamber side wall by mixed flow mouth 206.Along the flowing of fluid
Direction, the upper end level of the mixed flow mouth are higher than the lower end height of the recoil structure.By the design of mixed flow mouth 206, not only
It can be mixed the fluid between different reaction channels, while also help the pressure between the different reaction channel of balance
Power, so that fluid mixing is more abundant.Microreactor of the present invention, channel form can greatly increase micro passage reaction
Treating capacity.Due to common microreactor, the pressure loss to be present serious, therefore high energy consumption, and microreactor of the present invention can be with
It is in parallel using four-way, mixed flow mouth 206 is provided between its parallel port, can on the one hand ensure that every leads to mixed flow each other
Fluid flow is identical in road, on the other hand, reduces the pressure loss of unit length reaction channel.
Because using four-way, the in parallel and form of UNICOM, liquid holdup increase, unit length pressure drop substantially reduces, so as to
Energy consumption can be reduced.Preferably, the upper end level of the mixed flow mouth is higher than the lower end height of the recoil structure, so as to effectively
Promote the mixed flow effect of the mixed flow mouth.
Microreactor provided by the invention, fluid maintain in prismatic fluidic channel and transmit the high-velocity fluid, energy
It is enough effectively prevent the high-velocity fluid after accelerating be directly entered the big flow channel space in downstream so as to reduction of speed, do not have the effect of jet impulse
And the hybrid reaction degree of fluid can not be improved, prevent the high-velocity fluid after accelerating by the jet for unloading speed, improving fluid quickly
The effect of impact, the abundant degree of mixing for improving fluid, correspond to recoil structure in fluidic channel exit, realize to fluidic channel
The recoil of high-velocity fluid, and and then convection body shunted, promote fluid in medium be sufficiently mixed.
It will be readily appreciated by those skilled in the art that on the premise of not conflicting, above-mentioned each advantageous manner can be freely
Combination, superposition.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
