Description
Technical field
The utility model relates to reaction unit field, it is specifically a kind of collect circulation reaction, fixed bed reaction, chromatography function in
The combined reaction apparatus platform of one.
Background technique
Traditional reaction kettle heat exchange specific surface is 0.1cm2/ml~0.05cm2/ml, and the heat transfer specific surface that microchannel plate is answered is
100cm2/ml~10cm2/ml, the two differ the 3-4 order of magnitude.
Microchannel continuous reaction was increasingly taken seriously in fields such as chemical industry, pharmacy, biologies in recent years, this depends on it
Exclusive structural advantage.The specific surface that microchannel plate is answered is greater than traditional thousands of times of still reaction, traditional reaction kettle heat exchange specific surface
For 0.1cm2/ml~0.05cm2/ml, the heat transfer specific surface that microchannel plate is answered is 100cm2/ml~10cm2/ml, the two difference
The 3-4 order of magnitude is also thousands of times of traditional reaction kettle by control ability of the heat transferring medium to reaction heat condition.Not for heat
Stable substance or intermediate state needs to be reacted in extremely low temperature, and it is with temperature, instead that side reaction, which occurs, for unstable intermediate state
Closely related between seasonable, temperature is higher, and side reaction is more significant, and the time is longer, and side reaction is more obvious.Microchannel successive reaction can
It is solved these problems with good, the heat transfer area of large scale can maintain reacting fluid to be quickly cooled to react better suited temperature
The heat of degree, reaction process release removes reaction system by heat exchange moment, guarantees that the temperature of reaction environment is stablized, thus really
Protect the data stabilizations such as reaction conversion ratio, yield and quality, impurity.
When carrying out hazardous chemical reaction, often with huge thermal discharge, if the heat of release cannot be by timely
Reaction system is removed, the heat of generation can continue to increase the temperature of reaction system, when temperature reaches the boiling point of solvent, or reach
The critical value of secondary response will cause pernicious safety accident, this is the major reason that accident occurs for many still reactions.It is micro-
Channel continuous production can extraordinary solution such issues that.Huge heat transfer specific surface can be by the temperature control of reacting fluid
System guarantees that reaction carries out in safe range in safety and optimal reaction temperature.Successive reaction carries out in channel, in channel
Reaction solution possess one thousandth that volume is traditional reaction kettle to a ten thousandth, risk factor can be reduced significantly, shadow
Ringing consequence can substantially reduce.
An important factor for mass transfer condition is chemistry, biology and many physical processes, traditional reaction kettle is in whipping process meeting
There is inhomogeneities spatially, such as when material specific gravity difference, whipping process just has inhomogeneities from depth direction.When
A kind of material dropping is added portionwise in reaction kettle, and this material has been uniformly mixed one section with reaction system under stirring
Time, this period can gradually extend with the amplification of reaction scale, time, not be uniformly mixed preceding this material just
Can be in local over-concentration, the degree that the longer side reaction of this time carries out will be bigger.It is first batch of during dropwise addition or batch charging
The material that the material and last batch of being included in are added has huge difference on the reaction time, this species diversity can be anti-with autoclave
It answers the amplification of scale to be gradually increased, reacts the product, intermediate, transition state of generation, experience longer side reaction reaction this period
It is more significant.Continuous microchannel plate should be that moment mixes under temperature, pressure appropriate by reaction mass, time of contact between material
Uniform, material is consistent in reaction condition retention time, efficiently controls the generation of side reaction, thus improve reaction conversion ratio and
Yield reduces reaction purification difficulty, increases economic efficiency.
Microchannel plate should be that serialization carries out, and material is conveyed by pump, and automation easy to accomplish reduces labour
Intensity reduces occupational injury risk.Continuous reaction carries out in channel, and material exposure link is few, reduces environmental pollution.Cause
This microchannel plate should either safety and environmental protection, labor intensity, in terms of suffer from fairly obvious advantage.
The concept that microchannel plate was answered in recent years is increasingly taken seriously in the production unit of each application field, in the market
There are different brands, various forms of micro passage reactions.Healthy and free from worry heart-shaped runner reactor, micro- triumphant pipeline type reaction
The Z-type runner reactor of device, Chemtrix has the example of successful application in different field.There are also quotient on domestic market
The product of product occurs.
But all these products have problems some in this way: 1. use, installation needs professional to operate, instrument and equipment spirit
Activity is not high.Many reactors are whole designs, and fixed form, flow channel length disposably install to form a set of equipment, then
Secondary adjustment needs professional to visit, and strongly limits R&D Professional or the freedom degree of engineers and technicians.2. almost institute
Microreactor be using reaction channel itself as design, develop emphasis, have ignored material prepare, conveying, item
A variety of coordinateds between reaction basic parameter and these conditions such as part control.It simply says, reaction channel only connects
One part of continuous reaction, the only configuration from material including the links such as pumping, temperature control, software balance from entering to going out
It is only ideal reactor.3. the different runners to reaction of use environment require to be different, commercialization instrument on sale at present
Device has overemphasized the importance of runner form, some reactions are higher to thermal transmission requirement, some reactions require height to mass transfer, has
A little reactions need to input or outputting granular material, and not a kind of runner can be with comprehensively solve, single runner design meeting shadow
Ring the flexibility used.4. instrument price is very high.It is inevitable in material selection to seek a kind of material comprehensively solve material environment
Using some extreme materials, these materials are often expensive, and processing technology is also sufficiently complex, therefore the price is very expensive, from
And cause instrument price high.5. causing microchannel plate that theory is answered to be difficult in application field due to inflexible for use, expensive
Universal, also just because of this, the use experience of application field is difficult to accumulate and pass on, and further constrains the general of instrument and theory
And the development and use of instrument and equipment are far from entering the epoch of a benign cycle.Microchannel continuous reaction so has
The instrument of advantage fails to play due value in scientific research, production.Market call it is a it is cheap, easy to use,
Strong flexibility, product feature-rich, maintenance cost is low, it would be highly desirable to there is product a in this way to fill up the blank in market.
