Description

TECHNICAL FIELD

[0001] The utility model relates to the field of chemical industry, in particular to a gas raw material supply module and a gas reaction equipment with the gas raw material supply module. BACKGROUND

[0002] Gas reaction is a chemical reaction, adding a specified gas to another compound, such as gas-solid catalytic reaction, gas-solid non-catalytic reaction, gas / liquid reaction, etc. Taking hydrogenation reaction as an example, hydrogen (H2) is added to another compound, usually an unsaturated organic compound. This reaction can be catalytic or non-catalytic, and can lead to the formation of various types of compounds. The main types of hydrogenation reactions include: catalytic hydrogenation, non-catalytic hydrogenation, asymmetric hydrogenation, semi-hydrogenation, regioselective hydrogenation, stoichiometric hydrogenation, etc.

[0003] The existing hydrogenation reaction equipment mainly consists of a plunger pump, high-pressure hydrogen, a pressure reducing valve, a gas flow controller, a reactor, a back pressure valve, and control accessories. The pressure of the reaction system is below 6 MPa at normal pressure, and the flow control range of hydrogen is 30-200 sccm. The existing hydrogenation reaction equipment uses a manual control mode. The principle architecture of the existing hydrogenation reaction equipment is shown in Figure 1 .

[0004] The manual operation steps of the existing gas reaction equipment are as follows: 1. manually fill the catalyst, after filling, vent the back pressure, put the reactor into the oil bath pot, check the air tightness of the device, if there is no leakage, set the temperature of the oil bath pot, manually back pressure the equipment to the required pressure through the branch (the branch is a passage connected in parallel with the flowmeter, hydrogen flows through the branch during back pressure to prevent excessive pressure difference between the two ends of the flowmeter, which may damage the flowmeter), set the flow of the flowmeter to ensure that stable bubbles flow out of the back end, prepare the raw material liquid, manually empty the plunger pump (when there is a bubble in the plunger pump inlet pipe, an injector needs to be used to manually empty the outlet of the pump), pump the feed, set the flow rates of the main pump and the auxiliary pump (the auxiliary pump mainly pumps the solvent, which is mixed with hydrogen first and then used to clean the catalyst), after the main pump finishes pumping the raw material liquid, the reaction is complete, after the reaction is complete, manually stop the main pump, increase the flow rate of the auxiliary pump to the flow rate of the main pump during the reaction, flush for 20 minutes, then remove the reactor, pour out the catalyst, flush the reactor at high flow, and finally complete the entire reaction.

[0005] The construction of existing automated hydrogenation equipment aims to improve the reaction efficiency of hydrogenation reactions in flow chemistry in terms of reaction channels, reaction volume, ease of operation, and safety. Currently, hydrogenation reactions are widely used in flow chemistry, but there are generally significant challenges and pain points in their use: although the principles of other gas reaction mechanisms differ depending on the type of gas-solid reaction, the overall reaction design concept is the same, and they also suffer from the shortcomings of the aforementioned automated hydrogenation equipment;

[0006] ① The process involves numerous steps, and most existing equipment is manually operated. Before the reaction, it is necessary to manually control the gas flow rate, reaction system pressure, reaction temperature, and manually purge the air from the plunger pump and set the pump flow rate. This operation is quite cumbersome, and any operational errors may damage the gas flow meter. During the reaction, it is necessary to check the plunger pump and gas flow for any abnormalities. After the reaction, it is necessary to manually change the pump flow rate, replace reagents, and perform elution treatment on the reactor. After treatment, the pipelines need to be flushed at a high flow rate. The entire process requires significant human intervention. Between different steps, the experimenter cannot operate the equipment in a timely manner, resulting in low equipment utilization. Currently, the average output of a single piece of equipment is only 0.5 reactions per day.

[0007] ② As one of the reaction conditions, the gas may be flammable and explosive. The lack of timely and effective control over the gas supply and flow rate has led to the failure of some reactions due to the gas stopping midway. This not only wastes a lot of time, but also causes project delays and even wastes raw materials.

[0008] ③ The current hydrogenation reaction framework is quite complex, with many gas control valves, all of which need to be manually operated in a fume hood. This affects experimental efficiency and safety to some extent, and improper operation may also damage the flow meter.

[0009] ④ When the reaction time is long or starts in the afternoon, the reaction will basically end after the staff leaves work. After the reaction liquid is pumped out, the plunger pump will run dry until the next day, which will not only affect the pump's lifespan but also waste electricity. In addition, the gas will not be shut off until the next day. Therefore, the equipment currently poses certain safety risks.

[0010] ⑤ The existing equipment and accessories are basically encased in the equipment, and there are many internal pipelines, making maintenance inconvenient. Utility Model Content

[0011] The utility model description section introduces a series of simplified concepts, all of which are simplifications of existing technologies in the field, and will be further explained in detail in the detailed description section.

[0027] The gas feedstock supply module is used to supply gas at a specified flow rate for the reaction.

[0028] The reaction module has multiple reactors, the inlet of which is used to provide the reaction environment;

[0029] The discharge module has multiple product bottles.

[0030] Preferably, in a further improvement to the gas reaction apparatus, the raw material supply module includes:

[0031] The second control valve 12 has its inlet connected to multiple raw material bottles 9, and is used to control the switching of reactants in different raw material bottles.

[0032] The main pump 13 is connected to the outlet of the first control valve 12 and its outlet is connected to the inlet of the third check valve 10. It is used to extract and transport raw materials.

[0033] The venting device is connected to the outlet pipeline of the main pump 13.

[0034] Preferably, in a further improvement of the gas reaction apparatus, the venting device includes:

[0035] The third control valve 14 is connected to the outlet pipeline of the main pump 13 and is used to switch the raw material reaction channel and the venting channel.

[0052] This invention utilizes structural design to achieve switching of feed, reaction, and discharge for different reactants. Combined with a corresponding operating procedure (which can be manually operated or automatically implemented by a controller), this invention theoretically allows for an unlimited number of continuous reactions.

This invention can achieve 24 / 7 continuous operation, significantly improving production efficiency compared to existing equipment, and more specifically, achieving at least the following technical effects:

[0053] 1. Reduce manual operation on the equipment, lower the complexity of equipment operation, and improve the safety of experimental personnel.

[0054] 2. The number of reaction channels has been greatly increased, from only being able to perform one experiment at a time to being able to continuously and automatically switch channels to complete up to 5 experiments.

[0055] 3. The structural design simplifies the cleaning process, transforming it from manual, repetitive pipeline cleaning to a control valve-controlled channel switching system, reducing manpower investment in pipeline cleaning.

[0056] 4. By setting up a first pressure transmitter and a second pressure transmitter, an abnormal shutdown alarm function can be realized. If the reaction system is abnormal (flow rate, pressure, temperature, etc.), an alarm can be triggered and the relevant equipment can be shut down, avoiding material waste and reducing the potential risks of hydrogen leakage.

[0057] 5. Increased flexibility between different reactions: pump flow rate, MFC flow rate, and system pressure are all controllable (manual or automatic control) between different reactions, and the flow rate and pressure can also be adjusted as needed after switching reactions.

[0058] 6. The reaction chamber automatically switches between different zones, using a bubble sensor to detect signals and determine whether to proceed to the next step.

[0059] 7. Increase the controllability of the reaction system by using a combination of check valves and control valves to achieve precise control of gas reactions (especially hydrogenation reactions).

[0130] The main pump 13 is connected to the outlet of the first control valve 12 and its outlet is connected to the inlet of the third check valve 10. It is used to extract and transport raw materials.

[0131] The venting device is connected to the outlet pipeline of the main pump 13.

[0149] Adding a first pressure transmitter 24 and a second pressure transmitter 25 can also add the following judgment functions;

[0150] 1. When the pressure of the second pressure transmitter 25 increases, the equipment initially assumes that the reactor is blocked and switches to the cleaning pipeline (cleaning liquid - empty reactor pipe - waste liquid). If the pressure of the second pressure transmitter 25 decreases, the cleaning operation is completed and the equipment switches to the second reaction. If the pressure of the second pressure transmitter 25 continues to rise, it indicates that the main reactor pipeline is blocked and the equipment is shut down for handling.

[0151] 2. If the pressure of the first pressure transmitter 24 drops significantly (e.g., exceeding the set threshold), it indicates a problem with the hydrogen source, and the equipment should be shut down.
