Description

Double-phase flow molecular reactor skid-mounted system
Technical Field
The invention relates to a skid-mounted system of a double-phase flow molecular reactor.
Background
The microreactor, namely a microchannel reactor, is a microreactor which is manufactured by utilizing a precision machining technology and has a characteristic dimension of 10-300 micrometers (or 1000 micrometers), wherein the 'micro' of the microreactor indicates that a channel of a process fluid is in a micrometer level, and does not indicate that the external dimension of a microreactor device is small or the yield of a product is small. Millions of microchannels can be contained in the microreactor, thus also achieving high throughput. The microchannel reactor can shorten the reaction time of common chemical reaction from several hours to tens of hours to several seconds to several minutes, and simultaneously solves the problems of large amount of heat and a large amount of byproducts released in the reaction. The microchannel reactor can accurately control the reaction temperature, and for the strong exothermic reaction, if the mixing and heat exchange efficiency is not high, the phenomenon of local overheating is easy to occur. And the interior of the microchannel has good heat transfer and mass transfer characteristics, so that the reaction temperature cannot be excessively accumulated, and the reaction temperature is accurately controlled within a certain range. The microchannel reactor technology is easy to popularize and produce safely, and potential hidden production hazards can be reduced due to good temperature control capability, so that the safe implementation of projects is ensured. And because the reactants in the microreactor belong to the micro-scale, even if byproducts are generated, a lot of byproducts are not generated, thereby realizing the intrinsic safety. The advantages of the reactor based on the microchannel are as follows:
(1) large specific surface area, high transfer rate, short contact time and less by-products
The characteristic dimension of the micro-reaction channel is small, and the heat transfer capacity, the mass transfer capacity and the reaction rate of the unit volume area are obviously enhanced. The specific surface area of the microchannel equipment can reach 1000-5000 m 2 /m 3 The heat transfer coefficient is up to 2000-20000W/(m) 2 ·K)。
(2) Rapid, direct amplification
The traditional amplification process has amplification effect, the amplification purpose is achieved by increasing the volume and the scale of production equipment, and the process is time-consuming and labor-consuming. The micro-reaction system is in a multi-channel structure, each channel is equivalent to an independent reactor, and the micro-reactors do not need to be subjected to scale amplification during the expansion production, and only the number of the micro-reactors needs to be increased, namely the number amplification.
(3) And is highly safe
A large amount of heat can be removed in time, so that the reaction temperature is maintained within a set range, and the possibility of accidents is reduced to the maximum extent.
(4) Good operability
The micro-reaction system has a modular structure, is good in portability, can realize dispersed construction in product use places and on-site production and supply, can adjust production by increasing or decreasing the number of channels and replacing modules according to market conditions, and has high operation flexibility.
Therefore, the microchannel reactor technology is receiving wide attention and is a trend of developing chemical synthesis equipment in the future. However, microchannel reactors also have disadvantages, which are mainly four-fold in comparison with conventional tank reactors.
The micro-channel is easy to block and difficult to clean
At present, a plurality of researches are carried out to prepare nano materials by utilizing a microreactor, and the microreactor has the characteristic of narrow distribution of particle sizes of obtained particles due to very high mixing efficiency. The micro-channel in the micro-reactor has small size and complex structure, solid materials can not pass through the micro-channel, if a large amount of solids are generated in the reaction, the micro-channel is extremely easy to block, so that the production can not be continuously carried out, and the micro-channel is difficult to clean. The problem of plugging of the microreactors has been the biggest obstacle to replacing batch reactors with microreactors.
Second pulsation problem of the pump
The microchannel reactor generally drives fluid through a mechanical pump, but most of the mechanical pumps generate pulsating flow, so that the fluid in the microreactor is unstable. One solution that currently enables a stable continuous flow is electroosmotic flow.
The corrosion problem of equipment
Corrosion of the microreactor channels by the fluids involved in the reaction is also a great problem. Due to the high specific surface area and the small microchannel characteristic dimension of the microreactor, even a tiny corrosion degradation effect has a very obvious effect on the microreactor, so that the microreactor has a high corrosion prevention requirement on the material of the channel, the manufacturing cost of the microreactor is undoubtedly increased, and the large-scale industrial application of the microreactor is limited.
Fourth step of industrial realization
The micro-reactor adopts 'number increasing amplification' to enlarge the capacity, and although the amplification cost can be effectively reduced, the processing capacity is greatly limited. Second, the amplification of microreactors appears simple, but is a significant challenge to achieve. When the number of the micro-reactors is greatly increased, the complexity of monitoring and controlling the micro-reactors is greatly increased, and the operation cost is greatly increased for the actual production.
When the microchannel reactor technology is applied to high-viscosity fluid mixing or used as a microreactor to prepare nano particles, a large amount of solid particles are generated instantaneously in the fluid mixing and reaction processes, so that the microchannel reactor can be blocked immediately, and the reaction is terminated.
Disclosure of Invention

The double-phase flow molecular reactor is an important method for realizing the rapid mixing of reaction materials in submicron droplets, and a skid-mounted system of the double-phase flow molecular reactor is a device for realizing the instantaneous mixing reaction of double-phase flow smoke.

The reaction form of the two-phase flow has the transmission force of gas, and the material transmission resistance is greatly reduced compared with that of a micro-channel reactor; the high-speed moving two-phase flow has the mass transfer effect of liquid, and the mass transfer process of the material is strengthened, so that the external resistance in the transfer process can be effectively reduced, the mass transfer reaction and the heat and mass transfer are strengthened, and the material mixing reaction is promoted.
