Description

Technical Field

[0001] The present application relates to the technical field of production systems, and in particular to a production device and a production system. Background Art

[0002] The production process of bis(fluorosulfonyl)imide salt is as follows: acetonitrile is used as solvent, triethylamine reacts with sulfuryl fluoride and ammonia to generate bis(fluorosulfonyl)imide salt, with the chemical formula HN(SO2F)2.

[0003] In the related art, a traditional stirred tank is used as a reaction carrier. The required reaction liquid (acetonitrile and triethylamine) is first pumped into the stirred tank, and then the reaction gas (ammonia and sulfuryl fluoride) is fed from the bottom of the stirred tank. At the same time, stirring is turned on and the reaction begins. During the reaction, ammonia and sulfuryl fluoride rise from the bottom of the stirred tank while reacting. During the stirring process, shear force is formed on the bubbles of the reaction gas to refine the bubbles, but the shear effect of stirring is limited. There are still many larger bubbles that float out of the liquid interface before the reaction is completed and are discharged with the exhaust gas, resulting in low production efficiency. Utility Model Content

[0004] In view of the above problems, the present application provides a production equipment to solve the problem of low production efficiency.

[0005] The present application provides a production device, including a stirring kettle, a reflux pipe and a first shearer; the stirring kettle is provided with a first opening and a second opening; the reflux pipe connects the first opening and the second opening; the first shearer is connected to the reflux pipe and is provided with an air inlet.

[0006] In the technical scheme of the embodiment of the present application, the liquid material in the stirring tank (including acetonitrile and / or triethylamine, and part of bis(fluorosulfonyl)imide triethylamine salt) can flow into the reflux pipe, and then enter the first shearer through the reflux pipe, and at the same time, the reaction gas (ammonia and sulfuryl fluoride) can enter the first shearer from the air inlet, and the liquid material and the reaction gas can be mixed and reacted in the first shearer. The materials after the mixed reaction in the first shearer can be refluxed into the stirring tank through the reflux pipe to continue the stirring reaction. In this process, since the first shearer is arranged on the flow path of the reflux pipe, the bubbles of the reaction gas can be fully sheared by the first shearer, so that the bubbles of the reaction gas can be fully reacted, thereby solving the problem of low production efficiency.

[0007] In some embodiments, the first shearing device includes a mixing chamber and a shearing piece; the mixing chamber is connected to the reflux pipe and is provided with an air inlet, and the shearing piece is provided in the mixing chamber. With this design, the liquid in the stirring tank enters the mixing chamber through the reflux pipe, and the reaction gas enters the mixing chamber through the air inlet, so that the reaction gas and the reaction liquid have a longer reaction time and space in the mixing chamber, so that the shearing piece in the mixing chamber can fully shear the bubbles of the reaction gas.

[0008] In some embodiments, the first shearing device is further provided with an air inlet pipe, a liquid inlet pipe and a liquid outlet pipe; the liquid inlet pipe connects the mixing chamber and the reflux pipe, the liquid outlet pipe connects the mixing chamber and the reflux pipe; the air inlet pipe is arranged through the air inlet and extends into the mixing chamber, and the shearing piece is arranged at the air outlet end of the air inlet pipe and is located in the mixing chamber. With such a design, the liquid material flowing through the reflux pipe can be smoothly introduced into the mixing chamber through the liquid inlet pipe, and the reaction gas can be smoothly introduced into the mixing chamber through the air inlet pipe, and the material in the mixing chamber can be smoothly guided to the reflux pipe through the liquid outlet pipe; in addition, by arranging the shearing piece at the air inlet end of the air inlet pipe and extending the air inlet end of the air inlet pipe into the mixing chamber, during the installation process, the shearing piece can be first fixedly installed at the air inlet end of the air inlet pipe, and then the air inlet end of the air inlet pipe can be extended into the mixing chamber, which can not only make the shearing piece more convenient to install in the mixing chamber, but also make the shearing piece better fixed in the mixing chamber.

[0009] In some embodiments, the shearing member is a wire mesh. With such a design, when the reaction gas enters the mixing chamber through the air inlet pipe, the bubbles of the reaction gas will repeatedly pass through the wire mesh, and the reaction gas can be sheared from large bubbles into small bubbles through the wire mesh, making the bubbles of the reaction gas thinner, and the bubbles of the reaction gas can be fully sheared. In this way, a good shearing effect can be achieved without setting up a power device, which can simplify the preparation cost.

[0010] In some embodiments, the wire mesh is provided with multiple layers, and the multiple layers of wire mesh are arranged in sequence along the axial direction of the air inlet pipe. Such a design, by distributing multiple layers of wire mesh at the air outlet end of the air inlet pipe, can increase the number of times the bubbles of the reaction gas pass through the wire mesh, and can more fully shear the bubbles of the reaction gas, thereby improving the shearing effect on the bubbles of the reaction gas.

[0011] In some embodiments, the screen is a screen with mesh size of 10 to 200. This design allows 1 square inch (25.4 mm x 25.4 mm) of screen area to have 10 to 200 mesh holes, which can shear multiple bubbles at one time, thereby improving the shearing efficiency and effect of the bubbles of the reaction gas.

[0012] In some embodiments, the liquid inlet pipe and the air inlet pipe are respectively located on two adjacent side walls of the mixing chamber. Such a design can make the liquid inlet direction and the air inlet direction be set at an angle, so that the liquid entering from the liquid inlet pipe and the reaction gas entering from the air inlet pipe can generate turbulent flow in the mixing chamber, and can be more fully mixed, so that the reaction is more complete.

[0013] In some embodiments, the liquid outlet end of the reflux pipe extends into the bottom of the stirring tank. Such a design can further fully mix the materials, prolong the reaction time of the reaction gas and the reaction liquid, and allow the unreacted liquid material and gas to fully react after being circulated back.

[0014] In some embodiments, a second shear is provided at the liquid outlet of the reflux pipe. With this design, when the material flows through the liquid outlet of the reflux pipe, the second shear can shear the bubbles of the reaction gas again, which can further shear the bubbles of the reaction gas, making the bubbles of the reaction gas thinner and the reaction more complete.

[0015] In some embodiments, the second shearing device is a wire mesh structure. With this design, when the reaction gas flows through the liquid outlet of the reflux pipe, the bubbles of the reaction gas will repeatedly pass through the wire mesh structure, and the wire mesh structure will further shear the reaction gas from large bubbles into small bubbles, making the bubbles of the reaction gas thinner, and the bubbles of the reaction gas can be fully sheared. In this way, a good shearing effect can be achieved without setting up a power device, which can simplify the preparation cost.

[0016] In some embodiments, the production equipment further comprises a pump body, which is arranged on the flow path of the reflux pipe, and the first shearing device is located at the outlet of the pump body. In such a design, by arranging the pump body on the flow path of the reflux pipe, the material can be pumped back to the stirring kettle through the pump body, and in this process, the material can flow smoothly through the first shearing device, so that the bubbles of the reaction gas can be fully sheared by the first shearing device.

[0017] In some embodiments, the first opening is disposed at the bottom of the stirring tank. Such a design can allow the material in the stirring tank to enter the reflux pipe more smoothly through the first opening while meeting the safety design requirements, and allow the material in the stirring tank to flow completely to the reflux pipe.

[0018] In some embodiments, the second opening is disposed at the top of the stirring tank. Such a design can prevent the material in the stirring tank from flowing back or overflowing through the second opening.

[0019] In some embodiments, the production equipment further includes a liquid supply pipe, which is connected to the reflux pipe and is located between the first shearer and the liquid outlet of the reflux pipe. With this design, the reaction liquid can enter the reflux pipe through the liquid supply pipe, and then enter the stirring tank through the reflux pipe, so that there is no need to open an additional liquid supply opening in the stirring tank, which can simplify the process.

[0020] The present application also provides a production system, including a liquid supply device, a gas supply device and the above-mentioned production equipment, wherein the liquid supply device is connected to a liquid inlet pipe of the production equipment, and the gas supply device is connected to an air inlet pipe of the production equipment.

[0035] The production process of bis(fluorosulfonyl)imide salt is as follows: acetonitrile is used as solvent, triethylamine reacts with sulfuryl fluoride and ammonia to generate bis(fluorosulfonyl)imide salt, with the chemical formula HN(SO2F)2.

[0036] In the related art, a traditional stirred tank is used as a reaction carrier. The required reaction liquid (acetonitrile and triethylamine) is first pumped into the stirred tank, and then the reaction gas (ammonia and sulfuryl fluoride) is fed from the bottom of the stirred tank. At the same time, stirring is turned on and the reaction begins. During the reaction, ammonia and sulfuryl fluoride rise from the bottom of the stirred tank while reacting. During the stirring process, shear force is formed on the bubbles of the reaction gas to refine the bubbles, but the shear effect of stirring is limited. There are still many larger bubbles that float out of the liquid interface before the reaction is completed and are discharged with the exhaust gas, resulting in low production efficiency.

[0037] Based on the above problems, the present application proposes a production device 100 for producing bis(fluorosulfonyl)imide salts, aiming to solve the problem of low production efficiency. Of course, in other embodiments, the production device 100 proposed in the present application can also be used to produce other products of gas-liquid mixed reactions.

[0038] Combined with reference Figure 1 and Figure 2The present application provides a production device 100, including a stirring tank 10, a reflux pipe 20 and a first shearer 30; the stirring tank 10 is provided with a first opening 111 and a second opening 112; the reflux pipe 20 is connected to the first opening 111 and the second opening 112; the first shearer 30 is connected to the reflux pipe 20 and is provided with an air inlet.

[0039] In the technical scheme of the embodiment of the present application, the liquid material in the stirring tank 10 (including acetonitrile and / or triethylamine, and part of bis(fluorosulfonyl)imide triethylamine salt) can flow into the reflux pipe 20, and then enter the first shearer 30 through the reflux pipe 20. At the same time, the reaction gas (ammonia and sulfuryl fluoride) can enter the first shearer 30 from the air inlet. The liquid material and the reaction gas can be mixed and reacted in the first shearer 30. The material after the mixed reaction in the first shearer 30 (which can be a liquid material or a gas-liquid mixture) can be refluxed to the stirring tank 10 through the reflux pipe 20 to continue the stirring reaction. In this process, since the first shearer 30 is arranged on the flow path of the reflux pipe 20, the bubbles of the reaction gas can be fully sheared by the first shearer 30, so that the bubbles of the reaction gas can be fully reacted, thereby solving the problem of low production efficiency.

[0040] In this embodiment, the stirring tank 10 includes a reaction tank 11 and a stirring paddle 12 , and the stirring paddle 12 is used to stir the material in the reaction tank 11 .

[0041] In this embodiment, the fixing method of the first shearer 30 is illustrated by way of example. It can be understood that the first shearer 30 can be locked with the return pipe 20 through a flange to facilitate the installation of the first shearer 30, or it can be installed on the return pipe 20 by way of sleeve docking, or it can be installed on the return pipe 20 by way of waterproof adhesive bonding.

[0042] In the present embodiment, the positions of the first opening 111 and the second opening 112 may not be specifically limited. It is understandable that the first opening 111 may be disposed at the top, bottom or side of the stirring tank 10, as long as the material in the stirring tank 10 can enter the reflux pipe 20 through the first opening 111. Similarly, the second opening 112 may also be disposed at the top, bottom or side of the stirring tank 10, as long as the material in the reflux pipe 20 can enter the stirring tank 10 through the second opening 112.

[0043] The reflux pipe 20 in this embodiment may directly reach the bottom of the stirring tank 10 after passing through the second opening 112 , or may only extend to the top or side of the stirring tank 10 .

[0044] In one embodiment of the present application, Figure 2The first shearing device 30 includes a mixing chamber 31 and a shearing piece 34 ; the mixing chamber 31 is connected to the return pipe 20 and is provided with an air inlet, and the shearing piece 34 is arranged in the mixing chamber 31 .

[0045] With this design, the liquid in the stirring tank 10 enters the mixing chamber 31 through the reflux pipe 20, and the reaction gas enters the mixing chamber 31 through the air inlet, so that the reaction gas and reaction liquid have a longer reaction time and space in the mixing chamber 31, so that the shearing piece 34 in the mixing chamber 31 can fully shear the bubbles of the reaction gas.

[0046] In this embodiment, the mixing chamber 21 includes three openings, two of which are inlets and the other is an outlet. One of the inlets is used to connect with the reflux pipe 20 to serve as a liquid inlet, and the other inlet is an air inlet to serve as an air inlet. The outlet is connected with the reflux pipe 20 to serve as a material outlet. After the liquid flowing out of the first opening 111 of the stirring tank 10 enters the reflux pipe 20, it can flow to one of the inlets of the mixing chamber 31 through the liquid inlet pipe 32, and the reaction gas can flow from the air inlet pipe 33 to the other inlet of the mixing chamber 31. The material after mixing and shearing in the mixing chamber 31 can flow from the outlet of the mixing chamber 31 to the reflux pipe 20, and then circulate back to the stirring tank 10 through the reflux pipe 20.

[0047] The shearing member 34 in this embodiment may be a grid structure, or may be a stirring blade or other structure capable of shearing.

[0048] In one embodiment of the present application, Figure 2 The first shearing device 30 is also provided with an air inlet pipe 33, a liquid inlet pipe 32 and a liquid outlet pipe 35; the liquid inlet pipe 32 connects the mixing chamber 31 and the return pipe 20, and the liquid outlet pipe 35 connects the mixing chamber 31 and the return pipe 20; the air inlet pipe 33 is passed through the air inlet and extends into the mixing chamber 31, and the shearing piece 34 is provided at the air outlet end of the air inlet pipe 33 and is located in the mixing chamber 31.

[0049] With such a design, the liquid flowing through the reflux pipe 20 can be smoothly introduced into the mixing chamber 31 through the liquid inlet pipe 32, and the reaction gas can be smoothly introduced into the mixing chamber 31 through the air inlet pipe 33, and the material in the mixing chamber 31 can be smoothly led to the reflux pipe 20 through the liquid outlet pipe 35. In addition, by arranging the shear piece 34 at the air inlet end of the air inlet pipe 33, and extending the air inlet end of the air inlet pipe 33 into the mixing chamber 31, during the installation process, the shear piece 34 can be first fixedly installed at the air inlet end of the air inlet pipe 33, and then the air inlet end of the air inlet pipe 33 can be extended into the mixing chamber 31, which not only makes it more convenient to install the shear piece 34 in the mixing chamber 31, but also makes the shear piece 34 better fixed in the mixing chamber 31.

[0050] The shear piece 34 in this embodiment can be fixedly installed on the air intake end of the air intake pipe 33 by bonding, screw connection, clamping, etc., so as to improve the installation reliability of the shear piece 34.

[0051] In one embodiment of the present application, Figure 2 , the shearing piece 34 is a wire mesh.

[0052] With such a design, when the reaction gas enters the mixing chamber 31 through the air inlet pipe 33, the bubbles of the reaction gas will repeatedly pass through the wire mesh, and the reaction gas can be sheared from large bubbles into small bubbles by the wire mesh, making the bubbles of the reaction gas finer, which can fully shear the bubbles of the reaction gas. In this way, a good shearing effect can be achieved without setting up a power device, which can simplify the preparation cost.

[0053] The wire mesh in this embodiment can be a metal wire mesh or a plastic wire mesh, as long as it does not affect the normal reaction, and no specific limitation is made here.

[0054] In one embodiment of the present application, Figure 2 The wire mesh is provided with multiple layers, and the multiple layers of wire mesh are arranged in sequence along the axial direction of the air intake pipe 33.

[0055] Such a design, by distributing multiple layers of screens at the outlet end of the air inlet pipe 33, can increase the number of times the reaction gas bubbles pass through the screens, and can more fully shear the reaction gas bubbles, thereby improving the shearing effect on the reaction gas bubbles.

[0056] In this embodiment, two adjacent layers of screens are arranged at intervals.

[0057] In one embodiment of the present application, Figure 2 The screen is a screen of 10 to 200 meshes. Specifically, the screen can be a screen of 10 meshes, 80 meshes, 100 meshes, 150 meshes, or 200 meshes.

[0058] Such a design can provide 10 to 200 mesh holes on a 1 square inch (25.4 mm x 25.4 mm) screen area, and can shear multiple bubbles at one time, thereby improving the shearing efficiency and effect of the bubbles of the reaction gas.

[0059] In one embodiment of the present application, Figure 1 and Figure 2 The liquid inlet pipe 32 and the air inlet pipe 33 are respectively located on two adjacent side walls of the mixing chamber 31 .

[0060] Such a design allows the liquid inlet direction and the gas inlet direction to be set at an angle, so that the liquid entering from the liquid inlet pipe 32 and the reaction gas entering from the gas inlet pipe 33 can generate turbulence in the mixing chamber 31, and can be mixed more fully, making the reaction more complete.

[0061] In this embodiment, the liquid inlet direction of the liquid inlet pipe 32 and the air inlet direction of the air inlet pipe 33 can be 30 degrees, 60 degrees, 90 degrees, 120 degrees, etc.

[0062] In one embodiment of the present application, Figure 1 The liquid outlet end of the reflux pipe 20 extends into the bottom of the stirring tank 10.

[0063] Such a design can further fully mix the materials to extend the reaction time of the reaction gas and the reaction liquid, so that the unreacted liquid material and gas that are circulated back can fully react.

[0064] In one embodiment of the present application, Figure 1 A second shearing device 40 is provided at the liquid outlet end of the reflux pipe 20 .

[0065] With such a design, when the material flows through the liquid outlet of the reflux pipe 20 , the bubbles of the reaction gas can be sheared again by the second shearer 40 , which can further shear the bubbles of the reaction gas, making the bubbles of the reaction gas finer and the reaction more complete.

[0066] The second shearing device 40 in this embodiment may have the same structure as the first shearing device 30 or may have a different structure, as long as it can shear the bubbles of the reaction gas.

[0067] In this embodiment, the fixing method of the second shearer 40 is illustrated by way of example. It can be understood that the second shearer 40 can be locked with the return pipe 20 through a flange to facilitate the installation of the second shearer 40, or it can be installed on the return pipe 20 by way of sleeve docking, or it can be installed on the return pipe 20 by way of waterproof adhesive bonding.

[0068] In one embodiment of the present application, Figure 1 , the second shearing device 40 is a wire mesh structure.

[0069] With such a design, when the reaction gas flows through the liquid outlet end of the reflux pipe 20, the bubbles of the reaction gas will repeatedly pass through the wire mesh structure, and the reaction gas will be further sheared from large bubbles into small bubbles by the wire mesh structure, making the bubbles of the reaction gas thinner, and the bubbles of the reaction gas can be fully sheared. In this way, a good shearing effect can be achieved without setting up a power device, which can simplify the preparation cost.

[0070] The wire mesh structure in this embodiment can be a metal wire mesh or a plastic wire mesh, as long as it does not affect the normal reaction, and is not specifically limited here.

[0071] In one embodiment, the wire mesh structure may also be provided with multiple layers, and the multiple layers of wire mesh structures are arranged in sequence along the axial direction of the reflux pipe 20. Such a design can increase the number of times the bubbles of the reaction gas pass through the wire mesh structure, and can more fully shear the bubbles of the reaction gas, thereby improving the shearing effect on the bubbles of the reaction gas.

[0072] In one embodiment, the wire mesh structure may also be a wire mesh of 10 to 200 meshes. Specifically, the wire mesh structure may be a wire mesh structure of 10 meshes, 80 meshes, 100 meshes, 150 meshes, or 200 meshes. Such a design may allow the number of mesh holes on a 1 square inch (25.4 mm × 25.4 mm) wire mesh structure area to be 10 to 200, and may be able to shear multiple bubbles at one time, thereby improving the shearing efficiency and shearing effect of the bubbles of the reaction gas.

[0073] In one embodiment of the present application, Figure 1 The production equipment 100 further includes a pump body 50 , which is disposed on the flow path of the reflux pipe 20 , and the first shearing device 30 is located at the outlet of the pump body 50 .

[0074] With such a design, a pump body 50 is provided on the flow path of the reflux pipe 20 , and the material can be pumped back to the stirring tank 10 through the pump body 50 . During this process, the material can flow smoothly through the first shearer 30 , so as to fully shear the bubbles of the reaction gas through the first shearer 30 .

[0075] In some embodiments, a first valve body may be provided between the pump body 50 and the feed port of the reflux pipe 20, a second valve body may be provided between the pump body 50 and the first shearer 30, and a third valve body may be provided between the first shearer 30 and the discharge port of the reflux pipe 20 to flexibly control the opening and closing of each pipe section.

[0076] In one embodiment of the present application, Figure 1 The first opening 111 is disposed at the bottom of the stirring tank 10 .

[0077] Such a design can, under the condition of satisfying safety design, enable the material in the stirring tank 10 to enter the reflux pipe 20 more smoothly through the first opening 111 and enable the material in the stirring tank 10 to flow completely to the reflux pipe 20 .

[0078] In one embodiment of the present application, Figure 1 and Figure 2 The second opening 112 is disposed at the top of the stirring tank 10 .

[0079] Such a design can prevent the material in the stirring tank 10 from flowing back or overflowing through the second opening 112 .

[0080] In one embodiment of the present application, Figure 1 The production equipment 100 also includes a liquid supply pipe 60, which is connected to the return pipe 20 and is located between the first shearer 30 and the liquid outlet of the return pipe 20.

[0081] With this design, the reaction liquid can enter the reflux pipe 20 through the liquid supply pipe 60 and then enter the stirring tank 10 through the reflux pipe 20. This eliminates the need to open an additional liquid supply opening in the stirring tank 10, thereby simplifying the process.

[0082] The present application also proposes a production system, which includes a liquid supply device, a gas supply device and a production device 100. The specific structure of the production device 100 refers to the above embodiment. Since the present production system adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the liquid supply device is connected to the liquid inlet pipe 32 of the production device 100, and can provide the reaction liquid to the liquid inlet pipe 32, and the gas supply device is connected to the gas inlet pipe 33 of the production device 100, and can provide the reaction gas to the gas inlet pipe 33.
