Description

TECHNICAL FIELD

[0001] The present application relates to the field of chemical apparatus, in particular to a gas-liquid phase reactor and a reaction system. BACKGROUND

[0002] Hydrogen is an explosive energy gas and lighter than air, so it is not suitable for storage. In the chemical industry, hydrogen is often converted into methane for storage by reacting with carbon dioxide. Compared with the reaction in the gas phase, the reaction in the liquid phase can be carried out at a lower temperature and pressure, which is safer. However, the solubility of hydrogen in the liquid phase is low. In order to achieve efficient conversion of hydrogen in the liquid phase, the main strategies are to prolong the contact time between gas and liquid and increase the gas-liquid contact area.

[0003] CN102091586A discloses a gas-liquid phase reactor, which comprises a reactor shell, a gas phase inlet and a liquid phase inlet are arranged on the shell, a gas phase pipeline connected with the gas phase inlet is arranged in the shell, a stirring shaft is arranged at the center of the interior of the shell, a plurality of conical stirring discs are mounted on the stirring shaft, and a paddle is arranged at the lower end of the stirring shaft. The conical stirring disc of the gas-liquid phase reactor forms a conical gas chamber with the liquid phase, so that the contact surface between the gas phase and the liquid phase forms a conical atomization layer, which increases the contact opportunity between the gas phase and the liquid phase and improves the reaction conversion rate of the gas phase and the liquid phase.

[0004] However, the above-mentioned scheme adds a mechanical transmission mechanism in the gas-liquid phase reactor, which needs to be energized during use, resulting in high energy consumption during the reaction process. CONTENT OF THE UTILITY MODEL

[0005] The purpose of the present application is to provide a gas-liquid phase reactor and a reaction system, which can solve the problem of high energy consumption of the gas-liquid phase reactor during use.

[0006] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:

[0007] According to the first aspect of the present application, a gas-liquid phase reactor is provided, which comprises a shell and a suction member. The interior of the shell forms a containing cavity, and a gas inlet is arranged in communication with the containing cavity. The suction member is arranged in the containing cavity. The suction member is made of a hydrophobic material.

[0008] According to the above technical means, the accommodating cavity formed by the shell can accommodate the solution, so that the reaction can be carried out in the liquid phase. The setting of the gas inlet enables the reaction gas to enter the accommodating cavity through the gas inlet and be transported into the solution. The suction accessory is arranged in the accommodating cavity, so that the suction accessory can be in the liquid phase. The suction accessory is made of hydrophobic material, which exhibits gas affinity in the liquid phase, can adsorb the reaction gas in the liquid phase, and prolongs the contact time between the gas and the liquid. Therefore, the gas-liquid phase reactor provided by the embodiment of the present application prolongs the contact time between the gas and the liquid by using the hydrophobic material to adsorb the reaction gas, thereby ensuring the reaction efficiency while reducing the energy consumption of the gas-liquid phase reactor during use.

[0009] In a possible implementation, the gas-liquid phase reactor further comprises a fixing member, which is connected with the suction accessory. The fixing member is further detachably connected with the shell.

[0010] According to the above technical means, the suction accessory can be fixed in the accommodating cavity of the shell through the mutual connection of the fixing member with the suction accessory and the shell, and the suction accessory can be detached by directly detaching the fixing member, thereby facilitating the detachment of the suction accessory.

[0011] In a possible implementation, the number of the suction accessories is multiple.

[0012] According to the above technical means, the multiple suction accessories can adsorb more reaction gas, thereby prolonging the contact time between more reaction gas and the liquid phase and making the conversion rate of the reaction gas higher.

[0013] In a possible implementation, the multiple suction accessories are arranged at intervals along the extension direction of the fixing member.

[0014] According to the above technical means, the surfaces of the two suction accessories that are relatively spaced due to the interval arrangement of the multiple suction accessories can also be used to adsorb more reaction gas, thereby prolonging the contact time between more reaction gas and the liquid phase and making the conversion rate of the reaction gas higher.

[0015] In a possible implementation, the fixing member comprises two fixing parts, and the two fixing parts are arranged in a mutual winding manner. The part of the suction accessory between the two fixing parts extends in a direction perpendicular to the extension direction of the fixing member, and the extension directions of the adjacent two suction accessories are different.

[0016] According to the above technical means, the multiple suction accessories pass through the gap formed by the mutual winding of the two fixing parts. The two fixing parts play a role in fixing the suction accessory by clamping the part of the suction accessory between the two fixing parts. The extension directions of the adjacent two suction accessories are different, so that the adjacent two suction accessories are spaced in space, so that the suction accessory can adsorb more reaction gas, thereby prolonging the residence time of more reaction gas and making the conversion rate of the reaction gas higher.

[0017] In a possible implementation, the suction accessory is made of polytetrafluoroethylene material.

[0018] According to the above technical means, polytetrafluoroethylene is a super-hydrophobic material, which is super-gas-wet in liquid phase, so that the suction accessory has better adsorption capacity for the reaction gas.

[0019] In a possible implementation, the suction accessory has a sheet structure, and the suction accessory has a porous structure. The extension direction of the suction accessory is perpendicular to the shell.

[0020] According to the above technical means, when the reaction gas passes through the porous structure, the reaction gas is intercepted on one hand because the bubble size is larger than the size of the hole. On the other hand, the reaction gas stays on the suction accessory because of the adsorption of the suction accessory.

[0021] In a possible implementation, the gas-liquid phase reactor further comprises a bubble generator arranged in the accommodation cavity. The bubble generator is used to refine the gas.

[0022] According to the above technical means, the bubble generator can increase the gas-liquid contact area by refining the reaction gas into small bubbles, so as to improve the conversion rate of the reaction gas.

[0023] In a possible implementation, the bubble generator is an aeration stone.

[0024] According to the above technical means, because the aeration stone has a simple structure, it is easy to install and maintain. In addition, the aeration stone is generally made of corrosion-resistant material, which can resist the erosion of chemicals and microorganisms in the solution.

[0025] According to the second aspect of the present application, a reaction system is provided, comprising the gas-liquid phase reactor of any one of the first aspect.

[0026] It should be noted that the technical effects of the reaction system in the second aspect can be referred to the technical effects of the corresponding implementation in the first aspect, which will not be repeated here.

[0027] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present application. BRIEF DESCRIPTION OF DRAWINGS

[0041] In order to make the ordinary person skilled in the art better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings.

[0042] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0043] Hydrogen is an energy gas with the characteristics of being explosive and lighter than air, so it is not suitable for storage. In the chemical industry, hydrogen is often converted into methane for storage. This is because, on the one hand, the volumetric energy density of methane is higher than that of hydrogen, which means that methane can store more energy in the same volume, thereby reducing the demand for storage space. On the other hand, methane is easier to compress and liquefy than hydrogen. Methane can be compressed at a lower pressure and liquefied at a relatively high temperature (about -162℃), while hydrogen needs to be liquefied at a very low temperature (-253℃).

[0044] Compared with the conventional method of reacting hydrogen and carbon dioxide in the gas phase, setting the reaction environment in the liquid phase has the following advantages: first, some catalysts are more stable in the liquid phase, especially for those catalysts that are easily decomposed or deactivated at high temperatures. The liquid phase environment can provide better protection for the catalyst and prolong its service life. Second, in the liquid phase, the polarity and solubility of the reaction system can be changed by adjusting the type of solvent, thereby affecting the reaction rate and selectivity. Third, liquid phase reactions can usually be carried out at lower temperatures and pressures, which can reduce the cost of equipment and the risk of operation. In addition, low temperature and low pressure conditions may be necessary for some heat-sensitive materials. Fourth, for some reactants, liquid phase reactions may be safer than gas phase reactions. For example, the storage and transportation of gaseous hydrogen at high pressure may pose a safety hazard, while liquid phase reactions can reduce such risks.

[0045] However, hydrogen is a sparingly soluble gas, and the conversion rate to carbon-hydrogen compounds such as methane in the liquid phase is limited by the low solubility of the sparingly soluble gas. The Henry's constant reflects the ability of a gas to dissolve in a particular solvent at a given temperature and pressure. A larger Henry's constant means that the gas has a lower solubility in the solvent. The Henry's constant of hydrogen in pure water at 25℃ is about 7.1x10^4 atm / (mol / L), while the Henry's constant of carbon dioxide in pure water at 25℃ is about 2.9x10^-4 atm / (mol / L), which means that the solubility of hydrogen in pure water is much lower than that of carbon dioxide in pure water, which greatly limits the conversion rate of carbon-hydrogen compounds. The process of hydrogen gas from the gas phase crossing the phase interface into the liquid phase and diffusing in the liquid phase is called mass transfer of hydrogen in the liquid phase, which can be described by the following formula.

[0046] R t = 22.4 K La (H 2gTh -H 21 )

[0047] where R tThis is the hydrogen gas-liquid transport flux, describing the rate at which gas crosses the phase interface and enters the liquid phase, measured in L·L⁻¹. -1 反应器 day -1 K La The mass transfer coefficient of hydrogen gas is expressed in days. -1 H 2gTh The concentration of hydrogen in the gas phase, expressed in mol·L⁻¹. -1 H 21 This indicates the amount of hydrogen dissolved in the liquid phase, expressed in mol·L⁻¹. -1 .

[0048] In gas-liquid phase reactions, increasing the solubility of hydrogen and the gas-liquid mass transfer coefficient, as well as prolonging the contact time between the gas and liquid phases, are the main strategies for achieving efficient hydrogen conversion. The gas-liquid mass transfer coefficient of hydrogen is related not only to the physical properties of hydrogen and the solution itself (such as density, viscosity, and surface tension), but also to the gas-liquid phase contact area. The larger the gas-liquid phase contact area, the larger the gas-liquid mass transfer coefficient.

[0049] To achieve the reaction of hydrogen and carbon dioxide in the liquid phase, a suitable gas-liquid phase reactor is required. In the field of chemical engineering, related technologies often employ the addition of a stirring mechanism to the gas-liquid phase reactor to increase the gas conversion rate in the liquid phase. The stirring mechanism can create turbulence in the liquid phase, prolonging the travel distance of the bubbles and thus extending the contact time between the gas and liquid.

[0050] However, most gas-liquid phase reactors incorporate mechanical transmission mechanisms, which require energy-consuming movements during operation, resulting in high energy consumption during the reaction process.

[0051] To address the issue of high energy consumption during operation caused by the introduction of mechanical transmission mechanisms in gas-liquid phase reactors, this application provides a reaction system, such as... Figure 1 As shown, Figure 1 This is a schematic diagram of a reaction system 100 provided in an embodiment of this application. The reaction system 100 includes a gas bag 1, a gas-liquid phase reactor 2, and multiple gas pipes 3. The gas bag 1 includes several inlets and several outlets, and the gas bag 1 and the gas-liquid phase reactor 2 are connected by two gas pipes 3 to form a circulation loop. The gas bag 1 stores the reaction gas, which is transported into the gas-liquid phase reactor 2 through one outlet and one gas pipe 3 for reaction. The unreacted reaction gas and the gas generated by the reaction are returned to the gas bag 1 through one inlet and another gas pipe 3, and continue to react through the circulation loop until all of them are converted into the generated gas.

[0052] like Figure 1As shown, the reaction system 100 also includes a gas storage tank 4 and a pressure reducing valve 5. The gas bag 1 is connected to the gas storage tank 4 via another air inlet and a gas pipe 3. The gas storage tank 4 stores compressed reaction gas. This allows for the storage of more reaction gas for the reaction within the entire reaction system 100. The pressure reducing valve 5 is installed at the end of the gas storage tank 4 connected to the gas pipe 3. The pressure reducing valve 5 is used to reduce the pressure of the compressed gas in the gas storage tank 4 and deliver it to the gas bag 1 through the air inlet.

[0053] In addition, see also Figure 1 The reaction system 100 also includes an air pump 6. When the above components are connected through the air pipes 3, an air pump 6 is provided in each air pipe 3 to drive the gas flow.

[0054] In one possible implementation, the reaction system 100 further includes a gas detector 7, which is connected to the gas bag 1 via a gas pipe 3 and another gas outlet, and is used to detect the gas composition in the gas bag 1 to determine whether the reaction is complete.

[0055] like Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of a gas-liquid phase reactor 2 provided in an embodiment of this application. The gas-liquid phase reactor 2 includes a shell 21 and an adsorbent 22, with a receiving cavity formed inside the shell 21. Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of a housing 21 provided in an embodiment of this application. The housing 21 has an air inlet 23 communicating with a receiving cavity. Thus, the receiving cavity formed by the housing 21 can contain a solution, allowing the reaction to take place in the liquid phase. The air inlet 23 allows the reaction gas to enter the receiving cavity through the air inlet 23 and be delivered into the solution. Figure 2 As shown, the adsorption element 22 is disposed within the receiving cavity. The adsorption element 22 is made of a hydrophobic material.

[0056] In one possible implementation, the shell 21 also has a gas outlet communicating with the receiving cavity. This allows the gas generated in the gas-liquid phase reactor 2, or any unreacted gas, to flow out through the gas outlet.

[0057] In one possible implementation, the shell 21 also has a feeding port that communicates with the receiving cavity. This allows the solution and catalyst to be added into the receiving cavity through the feeding port.

[0058] The suction accessory 22 is arranged in the accommodating cavity so that the suction accessory 22 can be in the liquid phase. The suction accessory 22 is made of a hydrophobic material which exhibits a gas affinity in the liquid phase, and can adsorb the reaction gas in the liquid phase, thereby prolonging the contact time between the gas and the liquid. Since the above-mentioned gas-liquid phase reactor 2 does not add a mechanical transmission structure, but uses the adsorption of the reaction gas by the hydrophobic material to prolong the contact time between the gas and the liquid, the problem of complex structure and easy damage of the gas-liquid phase reactor 2 is avoided.

[0059] In order to realize the connection between the suction accessory 22 and the shell 21, in a possible implementation manner, as shown in Figure 2 , the suction accessory 22 is connected with the shell 21. In this way, the suction accessory 22 is fixed in the accommodating cavity by the connection with the shell 21, so as to be in full contact with the solution.

[0060] The above-mentioned connection can have various forms. Exemplarily, the connection between the suction accessory 22 and the shell 21 is fixed connection.

[0061] Of course, in another possible implementation manner, in order to realize the connection between the suction accessory 22 and the shell 21, as shown in Figure 4 , the suction accessory 22 is connected with the shell 21. Figure 4 A structural schematic diagram of a gas-liquid phase reactor 2 provided by the embodiment of the present application is shown in the figure. The gas-liquid phase reactor 2 further comprises a fixing member 24, and the fixing member 24 is connected with the suction accessory 22. The fixing member 24 is further detachably connected with the shell 21.

[0062] In this way, the suction accessory 22 can be fixed in the accommodating cavity of the shell 21 by the mutual connection between the fixing member 24 and the suction accessory 22 and the shell 21, and the suction accessory 22 connected with the fixing member 24 can be detached by directly detaching the fixing member 24, thereby facilitating the detachment of the suction accessory 22.

[0063] The connection between the fixing member 24 and the suction accessory 22 can have various forms. For example, the connection between the fixing member 24 and the suction accessory 22 can be movable connection. The movable connection enables the suction accessory 22 to slightly move in the accommodating cavity, and these slight movements can make the suction accessory 22 more easily capture the reaction gas in the liquid phase. Of course, the connection between the fixing member 24 and the suction accessory 22 can also be fixed connection, and the fixed connection makes the connection between them more stable.

[0064] In a possible implementation manner, as shown in Figure 2 , the number of the suction accessories 22 is multiple. In this way, the multiple suction accessories 22 can adsorb more reaction gas, thereby prolonging the contact time between more reaction gas and the liquid phase, and making the conversion rate of the reaction gas higher.

[0065] Of course, in a possible implementation, the number of suction accessories 22 can be single. In this way, the difficulty of setting the suction accessories 22 and the production cost of the gas-liquid phase reactor 2 are reduced.

[0066] In a possible implementation, as shown in Figure 4 , the plurality of suction accessories 22 are arranged at intervals along the extension direction of the fixing member 24.

[0067] In this way, the surfaces of the two suction accessories 22 that are relatively spaced due to the interval arrangement of the plurality of suction accessories 22 can also be used to adsorb more reaction gas, thereby prolonging the contact time of the reaction gas with the liquid phase and making the conversion rate of the reaction gas higher.

[0068] In a possible implementation, the plurality of suction accessories 22 are arranged adjacent to each other along the extension direction of the fixing member 24. In this way, more suction accessories 22 can be arranged in the same space.

[0069] In a possible implementation, the plurality of suction accessories 22 are arranged at intervals along another direction intersecting the extension direction of the fixing member 24. In this way, the suction accessories 22 can adsorb reaction gas at multiple positions in the accommodation cavity.

[0070] In a possible implementation, as shown in Figure 5 , the plurality of suction accessories 22 are arranged at intervals along the extension direction of the fixing member 24. Figure 5 A partial structure schematic diagram of a gas-liquid phase reactor 2 provided by an embodiment of the present application, the fixing member 24 includes two fixing portions 241, and the two fixing portions 241 are arranged in a mutual winding manner. Among them, a part of the suction accessories 22 is located between the two fixing portions 241, extends along a direction perpendicular to the extension direction of the fixing member 24, and the extension directions of the two adjacent suction accessories 22 are different.

[0071] In this way, the plurality of suction accessories 22 pass through the gap formed by the mutual winding of the two fixing portions 241. The two fixing portions 241 play a role in fixing the suction accessories 22 by clamping the part of the suction accessories 22 located between the two fixing portions 241. The suction accessories 22 extend along a direction perpendicular to the extension direction of the fixing member 24, and as shown in Figure 6 , the extension directions of the two adjacent suction accessories 22 are different. Figure 6 A partial structure schematic diagram of a gas-liquid phase reactor 2 provided by an embodiment of the present application, the extension directions of the two adjacent suction accessories 22 are different, which makes the two adjacent suction accessories 22 keep three-dimensional intervals in space. These intervals make the suction accessories 22 can adsorb more reaction gas, thereby prolonging the residence time of more reaction gas and making the conversion rate of the reaction gas higher.

[0072] In a possible implementation, the suction accessories 22 are made of polytetrafluoroethylene material.

[0073] Polytetrafluoroethylene is a super-hydrophobic material, which is super-gas-wet in liquid phase, so that the adsorption capacity of the adsorption accessory 22 for the reaction gas is better.

[0074] In a possible implementation, the fixing member 24 is a titanium wire.

[0075] In this way, the titanium wire has excellent corrosion resistance and can be used for a long time in a corrosive environment. In addition, the fixing member 24 can also be made of other materials, but the selected material needs to enable the reaction to proceed correctly, and other materials are not described here.

[0076] In order to prepare the gas-liquid phase reactor 2, the gas-liquid phase reactor 2 can also have a corresponding preparation process. For example, Figure 7 as shown, Figure 7 a preparation process diagram of a gas-liquid phase reactor 2 provided by an embodiment of the present application, which preparation process can include S100-S500.

[0077] S100: cut the sheet-shaped polytetrafluoroethylene into a plurality of 7cm long polytetrafluoroethylene fiber wires along the short edge direction, and arrange them along the long edge direction.

[0078] as shown, Figure 8 as shown, Figure 8 a partial structure diagram of an adsorption accessory 22 provided by an embodiment of the present application, which cuts the sheet-shaped adsorption accessory 22 into a wire shape.

[0079] S200: clamp the polytetrafluoroethylene fiber wire arranged in the titanium wire folded once.

[0080] as shown, Figure 9 as shown, Figure 9 a partial structure diagram of a gas-liquid phase reactor 2 provided by an embodiment of the present application, which uses a fixing member 24 to clamp the adsorption accessory 22.

[0081] S300: twist the titanium wire to make a polytetrafluoroethylene brush.

[0082] as shown, the twisted fixing member 24 makes the adsorption accessory 22 form a brush structure. Figure 5

[0083] S400: the prepared polytetrafluoroethylene brush is washed with anhydrous ethanol and deionized water three times in turn and dried for standby.

[0084] S500: assemble the polytetrafluoroethylene brush into the containing cavity.

[0085] In this way, by step S400, some impurities remaining on the adsorption accessory 22 can be avoided from entering the gas-liquid phase reactor 2, thereby affecting the correct reaction.

[0086] In a possible implementation, as Figure 10 ​As shown, Figure 10 A structure diagram of a gas-liquid phase reactor 2 is provided in the embodiments. The adsorption member 22 is in a sheet structure, and the adsorption member 22 is in a porous structure. The extension direction of the adsorption member 22 is perpendicular to the extension direction of the shell 21.

[0087] In this way, when the reaction gas passes through the porous structure, the reaction gas will be intercepted on one hand because the bubble size is larger than the size of the hole. On the other hand, the reaction gas will stay on the adsorption member 22 because of the adsorption effect of the adsorption member 22.

[0088] In a possible implementation, as shown, Figure 10 The sheet adsorption member 22 can be multiple, and the size of the hole in the porous structure in different adsorption members 22 can gradually decrease along the flow direction of the reaction gas.

[0089] In this way, the reaction gas can be intercepted and adsorbed in layers, and the conversion rate of the reaction gas can be improved.

[0090] In a possible implementation, as shown, Figure 10 The gas-liquid phase reactor 2 further includes a bubble generator 25 arranged in the containing cavity. The bubble generator 25 is used to refine the gas. In this way, the bubble generator 25 can increase the gas-liquid contact area by refining the reaction gas into small bubbles, so as to improve the conversion rate of the reaction gas.

[0091] In a possible implementation, the bubble generator 25 is an aeration stone. Because the aeration stone has a simple structure, it is easy to install and maintain. In general, the aeration stone is made of corrosion-resistant materials, which can resist the erosion of chemicals and microorganisms in the solution.

[0092] In a possible implementation, a stirrer is further arranged in the containing cavity. The stirrer includes a stirring shaft and a stirring paddle. The stirring paddle rotates around the stirring shaft. In this way, the rotation of the stirring paddle can generate turbulence in the solution, prolong the rising path of the reaction gas, thereby prolonging the contact time between the gas and the liquid, and further improving the conversion rate of the reaction gas.

[0093] Considering the phenomenon of gas boiling or liquid boiling that may occur in the reaction. Therefore, in actual use, the volume of the liquid in the containing cavity can be less than the actual volume of the containing cavity. In this way, there will be a part of the empty space in the containing cavity, which can reserve enough space for the possible gas boiling or liquid boiling. For example, the total volume of the gas-liquid phase reactor 2 is 950 ml, and the volume of the liquid in the containing cavity can be 750 ml.

[0094] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any change or replacement within the technical scope disclosed by the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
