Description

Technical Field

[0001] The utility model relates to the technical field of chemical engineering, in particular to a micro-reaction multifunctional platform. Background Art

[0002] The microchannel reactor includes mixers, heat exchangers, reactor controllers, etc. required for the chemical unit. The microchannel is used to control the flow of reactants, the mixer is used to mix the reactants evenly, the reactor is used to achieve chemical reactions, and the separator is used to separate products and by-products. The overall structure of the microchannel reactor can be divided into two types: one is the overall structure, which is embodied in the form of a cross-flow or countercurrent heat exchanger, and can perform high-throughput operations in a unit volume. In the overall structure, only one operation step can be performed at the same time, and finally these corresponding devices are connected to form a complex system. The other is a layered structure. This type of system consists of a stack of modules with different functions, one operation is performed in one layer of modules, and another operation is performed in another layer of modules. The flow of fluids in each layer of modules can be controlled by an intelligent diversion device. For higher flux, some microchannel reactors or systems are usually operated in parallel. Microreactors can be divided into gas-solid catalytic microreactors, liquid-liquid microreactors, gas-liquid microreactors, and gas-liquid-solid three-phase catalytic microreactors. Continuous flow microreactors are an important chemical reaction device with the advantages of high efficiency, controllability and scalability. Its application in chemical synthesis and catalysis has been widely recognized. By carrying out reactions at a microscopic scale, continuous flow microreactors overcome many limitations of traditional reactors and provide higher reaction efficiency and selectivity. It plays an important role in chemical synthesis reactions, catalytic reactions, reaction condition optimization and new reaction development.

[0003] Microreactors are widely used, but so far, the equipment available on the market or that can be ordered is mainly single-set type equipment. However, in actual application, the synthetic reactions that often accompany it are multi-step. The first step may be a liquid-liquid reaction, and the second step may be a gas-liquid reaction. This causes users to purchase multiple sets of equipment and cannot carry out related synthetic experiments continuously, which not only costs more money, but also takes more time.

[0029] Working principle: Through the mutual series connection and parallel connection of multiple reaction modules 30, a set of equipment can be used for different types of reactions. During the use of the micro-reaction multifunctional platform, the dynamic tubular reactor 31, the multiphase catalytic reactor 32, the tubular reactor 33, and the plate reactor 34 can be used in series and in parallel. When a reactant needs to undergo multiple reactions, it is only necessary to input the reactant from the position of the infusion tube 5, and the input reactant is then transported to different reaction modules 30 through the infusion pump 4; when the reactant needs to undergo multiple reactions in sequence, the required different reaction modules 30 can be connected in series, and then the reactant can be transported by the infusion pump 4 so that the reactant can undergo different reactions in sequence; when the reactant needs to undergo different reactions at the same time or after undergoing a reaction, the reaction modules 30 that the reactant needs to react at the same time can be connected in parallel, and then the transport by the delivery pump allows the reactant to undergo different reactions at the same time or after undergoing a reaction. During the use of the device, since the device contains a variety of reaction modules 30, such as a dynamic tubular reactor 31, a multiphase catalytic reactor 32, a tubular reactor 33 and a plate reactor 34, these modules can be connected in series or in parallel according to the experimental requirements, so as to complete various types of reactions in one device. The user does not need to purchase a separate device for each reaction type. The modular design allows the user to flexibly configure and combine different reaction modules 30 according to the experimental requirements, making the most of existing resources, avoiding repeated investment and saving funds for purchasing multiple sets of equipment. In addition, the device adopts a continuous flow operation mode, which can complete multiple reaction steps in the same process in sequence without pausing or replacing equipment in the middle. The device is equipped with an infusion pump 4 and a control screen 7, which can accurately control the flow of reactants and reaction conditions and realize automatic operation. This continuous flow operation mode significantly reduces the reaction time and processing time. At the same time, the modular design makes the internal space utilization rate of the equipment box 10 high, and all reaction modules 30 and related accessories are integrated in an equipment box 10. The user only needs to store and manage this one device, rather than multiple different devices, avoiding the problem of multiple devices being scattered and simplified storage and management. The multiple reaction modules 30 integrated in one equipment box 10 make the maintenance and management of the equipment more centralized and systematic, thus reducing the management complexity and maintenance cost.
