Description
Technical field
The present invention relates to technical field of heat exchangers, and in particular to one kind is applied to chemical industry, the energy, power, military affairs, electronics etc.
Heat exchange micro-channel heat exchanger in field, the Reactive fluids mixing that is particularly suitable for use in heat exchange.
Background technology
In chemical field, two kinds of liquid substance mixing, reaction sometimes generates substantial amounts of reaction heat.If these reaction heat are not
It can in time shed, the temperature environment of above two liquid substance mixing will be changed, and then influence reaction rate and course of reaction.
Research shows that the control of temperature is on the very big influence of the presence such as course of reaction, product, speed in course of reaction.
Chinese patent literature CN105107443A discloses a kind of efficiently mixed heat transfer micro passage reaction, such as Fig. 1 and Fig. 2
It is shown, including dispersion mixing component 01, and several are arranged at the reaction solution runner matrix of the rear end of dispersion mixing component 01
02 and heat transferring medium runner matrix 03, the reaction solution runner matrix 02 and heat transferring medium runner matrix 03 be arranged alternately；It is described
Dispersion mixing component 01, which is provided with, makes two or more reaction solution is scattered to flow into and be mixed to form the scattered of mixed reaction solution
Hybrid channel 04, the reaction solution runner matrix 02 are provided with reaction solution runner 021 and heat transferring medium through hole 022, the heat exchange
Medium runner matrix 03 be provided with reaction solution via hole 031, heat transferring medium runner 032 and with heat transferring medium runner 032 turn on
Ostium 033, tap hole 034；The reaction solution runner 021 of two adjacent reaction solution runner matrixs 02 is cascaded structure, two kinds
Or two or more reaction solutions flow into from the front end of dispersion mixing component 01 is scattered, the dispersion mixing in dispersion mixing passage 04, from
The rear end outflow of dispersion mixing component 01, into the reaction solution runner 021 of reaction solution runner matrix 02；Two adjacent heat exchange
The heat transferring medium runner 032 of medium runner matrix 03 is parallel-connection structure, and ostium 033 and the heat exchange communicated with ostium 033 are situated between
Matter through hole 022 forms flow channel, and it is logical that tap hole 034 and the heat transferring medium through hole 022 communicated with tap hole 034 form outflow
Road, heat transferring medium flow into from flow channel, and the heat exchange that respective heat transferring medium runner matrix 03 is respectively enterd from ostium 033 is situated between
Mass flow road 032, enter flow pass convergence outflow through respective tap hole 034.
Technical scheme in above-mentioned patent document, although the mixing of differential responses liquid can be realized, and mixing can be produced
Raw reaction heat distributes, but still at least has following technological deficiency：1) reaction solution mixing efficiency is low；Reaction solution runner mould
Although the inside of piece 02 is provided with a plurality of reaction solution runner 021, however between these reaction solution runners 021 except head and the tail position in addition to it is mutual not
Connection, due to the ratio between a variety of reaction solutions that can not ensure to be flowed into each reaction solution runner 021 inside with formation most
Ratio needed for whole mixed liquor is consistent, thus a variety of reaction solutions being even flowed into inside a reaction solution runner 021 can
It is sufficiently mixed, these reaction solutions will also be with the mixed liquor that is flowed out from other reaction solution runners 021 after the outflow of reaction solution runner 021
Mix again, so repeatedly, can just finally give well mixed mixed liquor；In addition, though reaction solution runner 021 is curved
Song setting, but this bending sets and can't bring more flow-disturbings, thus this bending setting pair to its liquid is flowed through
It is unsatisfactory in the mixing efficiency effect for accelerating reaction solution；2) reactor in above-mentioned patent document, reaction solution only with reaction solution
Two side walls of runner 021 and the contact of upper lower wall, heat exchange area is small, and then causes heat transfer coefficient low, and radiating effect is poor.

Cheng Zhong, treat that heat exchange unit 1 exchanges heat to press close to heat exchange unit 2；
Secondly, inject at least one fluid simultaneously to first fluid entrance 110 (can use when injecting multiple fluid at the same time
Multiple-pass joint), after fluid enters input area 11, flowed through channel region 13 to output area 12, in the process, fluid constantly rolls
Mixing, is fully exchanged heat with heat exchange unit 2；
Multiple when heat exchange unit 1 is arranged in parallel when having simultaneously, the fluid injected from first fluid entrance 110 can be through being located at
The first via on heat exchange unit 2, the first perforation being located on space bar 9, while to multiple input areas 11 for treating heat exchange unit 1
Flowing, so that multiple treat heat exchange unit 1 while start work；The fluid-mixing for flowing through hybrid channel area 13 can be through being located at heat exchange
The second via on unit 2, the second perforation being located on space bar 9 converge, and concentrate discharge.
Multiple heat exchange units can also be arranged in parallel when heat exchange unit 1 is arranged in parallel multiple, be entered from the second heat exchange liquid
The heat exchange liquid of mouthfuls 220 inputs are located on dividing plate 9 the 3rd and worn through being located at the 3rd via 83, the 4th via 84 treated on heat exchange unit 1
Hole, the 4th perforation, while flowed to the heat exchange liquid input area of multiple heat exchange units 2, so that multiple heat exchange units 2 start simultaneously
Work, flow through heat exchange liquid stream road heat exchange liquid can through being located at the 4th via 84 treated on heat exchange unit 1, be located on dividing plate 9 the
Four perforation converge, and concentrate discharge.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
