DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0030] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0031] The embodiment of the present application provides a separation device of a micro-reactor, which is mainly used for gas-liquid separation of reaction materials. The reaction materials are composed of a mixture of a reaction solution and a reaction gas. After a high-temperature and high-pressure reaction, the reaction materials need to be separated into gas and liquid by the separation device of the micro-reactor. Compared with the traditional method of gas-liquid separation by gravity sedimentation, the separation device of the present application can perform continuous gas-liquid separation, and can be performed under high temperature and high pressure, and can also ensure the separation speed and flow rate. Finally, the three-dimensional space of the separation device is small, which meets the industry requirements of micro-chemical technology.

[0032] like Figure 1 and 2 As shown, the separation device includes a first separation component 1, which includes a body 13. A coil 12 is provided in the body 13. The coil 12 is used to guide the reaction material, and one end of the coil 12 is connected to the reaction tube of the heating device. The heating device mainly performs a high-temperature reaction on the reaction solution and the catalyst. After the reaction, the reaction material flows into the coil 12. The first separation component 1 also includes a heat exchange part 11. The heat exchange part 11 can exchange heat with the reaction material in the coil 12 to improve the gas-liquid separation efficiency of the reaction material.

[0033] like Figure 2 、 4 As shown in Figure 7, the separation device also includes a second separation component 2, which includes a heat exchange body 21 and a detection body 22. The heat exchange body 21 is provided with a through accommodating cavity 2111 along the axial direction. The detection body 22 is arranged in the accommodating cavity 2111. The diameter of the detection body 22 is smaller than the diameter of the accommodating cavity 2111, so that a first gap 7 is formed between the outer surface of the detection body 22 and the inner circumferential wall of the accommodating cavity 2111. The second separation component 2 also includes a drainage pipe 4. The first end of the drainage pipe 4 is connected to the outlet of the coil 12, and the second end is connected to the first gap 7. The second end of the drainage pipe 4 is set to deviate from the axial direction of the heat exchange body 21, so that the axis of the drainage pipe 4 is staggered with the axis of the heat exchange body 21. In this way, when the reverse After the material passes through the heat exchange of the first separation component 1, preliminary gas-liquid separation will be performed. However, at this time, some bubbles will still be mixed in the reaction solution, and the separation is not complete. The reaction solution is guided to the first gap 7 through the second end of the drainage tube 4 in a direction deviating from the axial direction of the heat exchanger 21, so as to prevent the reaction solution from flowing into the first gap 7 along the outer peripheral wall of the heat exchanger 21 and the inner peripheral wall of the accommodating cavity 2111 on both sides of the axial direction of the drainage tube 4. The reaction solution entering the first gap 7 will flow into the first gap 7 in a spiral downward turbulent flow along the outer peripheral wall of the heat exchanger 21 and the inner peripheral wall of the accommodating cavity 2111 on the side deviated by the drainage tube 4. The continuous turbulence will further accelerate the gas-liquid separation, thereby improving the efficiency of gas-liquid separation.

[0034] Optionally, in the embodiment of the present application, in order to facilitate the description of the second end of the drainage tube 4 extending in a direction deviating from the axial direction of the heat exchanger 21, an example is given:

[0035] The axis directly opposite and perpendicular to the heat exchanger 21 is taken as the first perpendicular line, and the two sides of the first perpendicular line can be referred to as the first side and the second side. The axial direction of the drainage tube 4 is located on the first side or the second side, that is, the second end of the drainage tube 4 is set to deviate from the axial direction of the heat exchanger 21, so that the reaction solution will enter the first gap 7 along the first side or the second side, that is, it only enters the first gap 7 along one side of the outer periphery of the detection element and forms a spiral downward turbulent flow to improve the gas-liquid separation efficiency.

[0036] Optionally, the coil 12 is formed by coiling a stainless steel tube with an outer diameter of 1 / 16 inch and an inner diameter of 1 mm. The inner diameter of the formed coil 12 is 24 mm, the number of coil turns is 25, the lead is 2 mm, and the vertical height of the coil 12 is 50 mm.

[0037] Optionally, the first end of the drainage tube 4 is an inlet end, that is, an end connected to the coil 12 , and the second end of the drainage tube 4 is an outlet end, that is, an end connected to the first gap 7 .

[0038] Optionally, the heat exchange part 11 can be adjusted according to the actual situation according to the different separation temperatures of the reaction solution and the reaction gas. For example, when cooling is required, the heat exchange part 11 can be a fan, which cools the reaction materials in the coil 12 to separate the reaction solution and the reaction gas; when heating is required, the heat exchange part 11 can be a hot air blower, which can heat the reaction materials to separate the reaction materials and the reaction gas.

[0039] Optionally, in order to facilitate the installation between the heat exchange part 11 and the body 13, the heat exchange part 11 and the body 13 may be connected by bolts.

[0040] Optionally, in some cases, if the reaction material is subjected to gas-liquid separation by heating, the first separation component 1 may be closed, and the reaction material may be directly subjected to gas-liquid separation by the second separation component 2 .

[0041] like Figure 1 As shown, as an embodiment, a through chamber is provided in the body 13, the coil 12 is provided in the chamber and is placed in a spiral manner, and the inlet of the coil 12 is provided close to the heat exchange portion 11, and the outlet is provided away from the heat exchange portion 11. When the first separation component 1 is in use, the body 13 needs to be placed horizontally, that is, the axial direction of the chamber is horizontal. This is because as the temperature of the reaction material in the coil 12 drops or rises (depending on the specific reaction solution, if the reaction material needs to be heated to separate the reaction solution from the reaction gas, it needs to be heated). Temperature; if the reaction material needs to be cooled so that the reaction solution and the reaction gas can be separated, then cooling is required). According to Newton's law of internal friction, if the cooling process, the viscosity of the reaction solution in the coil 12 continues to increase, and the viscosity of the reaction gas continues to decrease, the reaction solution and the reaction gas directly produce a tendency to separate; the reaction material in the coil 12 is to do a spiral motion along the inner wall of the coil 12, which causes the reaction material to form turbulence. At the same time, the coil 12 is placed horizontally, and the reaction material adds a tangential force generated by gravity, which further increases the turbulence intensity of the reaction material;

[0042] Under the dual effects of turbulence and gravity, and due to the increasing viscosity of the reaction solution, the reaction materials in the coil 12 experience a phenomenon where the reaction solution continuously separates downward and toward the inner peripheral wall on the lower side of the coil 12, while the reaction gas separates from the middle of the coil 12 and gathers upward. Because the coil 12 is long enough, the reaction materials, which were originally a mixture of gas and liquid, become a state of gas and liquid at the outlet of the coil 12. If you carefully observe the condition of the reaction materials at the outlet, you will find that the flow of the reaction solution is no longer continuous, but intermittent, with large bubbles constantly emerging in the middle. The first separation component 1 has also achieved its cooling and gas-liquid separation effects.

[0043] Alternatively, if it is a temperature rising process, similarly, the viscosity of the reaction solution in the coil 12 continues to increase, the reaction gas tends to rise, and the reaction solution and the reaction gas tend to separate directly.

[0044] Optionally, the body 13 may be a frame structure or other structures, and a spiral groove communicating with the chamber may be provided inside the frame to facilitate embedding of the coil 12 therein.

[0045] like Figure 1 As shown, optionally, the first separation component 1 further includes a temperature sensor 14, which is used to sense the temperature of the reaction solution at the outlet of the coil 12 and transmit the temperature to the second separation component 2 for further gas-liquid separation by the second separation component 2.

[0046] like Figure 1 As shown, as an embodiment, the heat exchange portion 11 is arranged on one side of the main body 13, and the coil 12 is spirally arranged in the chamber to form multiple circles, and a second gap is directly provided between two adjacent circles, which is conducive to the full flow of the heat exchange gas on the outer peripheral wall of the coil 12, increasing the contact area between the outer peripheral wall of the coil 12 and the heat exchange gas, thereby allowing the reaction materials in the coil 12 to exchange heat quickly, thereby improving the efficiency of gas-liquid separation.

[0047] like Figure 1 As shown, as an embodiment, a notch 132 is provided on the body 13 for facilitating the installation of the coil 12 , and a plurality of vents 131 are also provided around the body 13 . The vents 131 facilitate the flow of heat exchange gas.

[0048] Optionally, the heat exchange gas in the embodiment of the present application can be cold air or hot air, which needs to be determined according to the temperature of gas-liquid separation.

[0049] like Figure 7 As shown, as an embodiment, the heat exchange body 21 includes a heat exchange body 211 and a heat exchange tube 212. The heat exchange body 211 is provided with a penetrating accommodating cavity 2111 along its axial direction. The accommodating cavity 2111 is coaxially arranged with the heat exchange body 211, and the detection component is located in the accommodating cavity 2111. The outer periphery of the heat exchange body 211 is provided with a spiral groove 2112, and at least part of the heat exchange tube 212 is embedded in the spiral groove 2112, thereby increasing the contact area between the heat exchange tube 212 and the heat exchange body 211. Heat exchange medium can flow in the heat exchange tube 212, and the heat exchange medium can transfer heat to the heat exchange body 211. The effect of this heat exchange is controllable. The heat exchange further increases or decreases the temperature of the reaction material and increases the viscosity of the reaction solution, so as to improve the heat exchange efficiency of the heat exchange body 211 to the reaction material in the first gap 7, and further improve the gas-liquid separation efficiency.

[0050] The heat exchange medium can be a propylene glycol aqueous solution, or a mixed solution of ethylene glycol and propylene glycol, or other solutions that can perform heat exchange.

[0051] Optionally, the depth of the spiral groove 2112 can be consistent with the diameter of the heat exchange tube 212, so that the heat exchange tube 212 is completely located in the spiral groove 2112. Of course, the depth of the spiral groove 2112 can also be smaller than the diameter of the heat exchange tube 212, so that the heat exchange tube 212 is partially embedded in the spiral groove 2112.

[0052] Optionally, the heat exchange tube 212 is embedded in the spiral groove 2112 , which, on the one hand, increases the contact area with the heat exchange body 211 and improves the heat exchange efficiency; on the other hand, provides stable support for the heat exchange tube 212 and prevents the heat exchange tube 212 from being scattered.

[0053] Optionally, the heat exchange body 211 may be made of aluminum alloy or copper, and the spiral groove 2112 may be an arc-shaped groove or other structures.

[0054] like Figure 4 、 5 As shown in Figure 7, as an embodiment, the detection body 22 includes a liquid level sensor 221, which extends into the accommodating cavity 2111 and is used to detect the height of the reaction solution in the first gap 7. If the height of the reaction solution in the first gap 7 is too high, it is necessary to control the flow rate of the reaction solution entering the first gap 7 to prevent the reaction solution from flowing out from the top of the first gap 7.

[0055] Optionally, the liquid level sensor 221 includes a connector and a detection rod connected to the connector, the detection rod extends from top to bottom into the accommodating cavity 2111 , and the connector protrudes from the outside of the heat exchange body 211 .

[0056] like Figure 4 and 5 As shown, as an embodiment, the detection body 22 also includes a sleeve 222, which is located on the outer periphery of the detection rod of the liquid level sensor 221. The sleeve 222 can be tightly connected with the detection rod of the liquid level sensor 221, or it can be loosely fitted with the detection rod of the liquid level sensor 221; a first gap 7 is formed between the sleeve 222 and the inner peripheral wall of the accommodating cavity 2111, so that the reaction material flows into the first gap 7 through the drainage tube 4. The material of the sleeve 222 can be stainless steel, etc.

[0057] like Figure 5As shown, optionally, a circle of first protrusions 213 is provided on the outer surface of the sleeve 222, and the first protrusions 213 are provided toward the inner peripheral wall of the accommodating chamber 2111, and the inner peripheral wall of the accommodating chamber 2111 is provided with a circle of second protrusions 223 opposite to the first protrusions 213, wherein a gap is provided between the first protrusions 213 and the second protrusions 223 to ensure that the reaction gas passes through, and the reaction solution in the reaction material in the first gap 7 will descend, while the reaction gas will rise. By providing the first protrusions 213 and the second protrusions 223, it is possible to prevent the reaction gas from carrying away tiny reaction solution molecules along the inner peripheral wall of the accommodating chamber 2111 and the outer peripheral wall of the sleeve 222 when rising, thereby making the gas-liquid separation more thorough.

[0058] Optionally, a sleeve 222 is provided on the outer periphery of the liquid level sensor 221, which is also convenient for setting the first protrusion 213 on the sleeve 222 to reduce production costs. However, setting the first protrusion 213 on the outer surface of the liquid level sensor 221 will increase production costs. Of course, in some cases, the outer periphery of the liquid level sensor 221 may also not be provided with a sleeve 222, and a circle of first protrusions 213 may be directly provided on the outer surface of the liquid level sensor 221, and a first gap 7 is formed between the liquid level sensor 221 and the inner peripheral wall of the accommodating cavity 2111.

[0059] Optionally, the height of the first protrusion 213 relative to the sleeve 222 can be 0.2 mm, and the height of the second protrusion 223 relative to the inner wall of the accommodating groove can be 0.2 mm, and the setting position of the first protrusion 213 and the second protrusion 223 must be higher than the height of the drainage tube 4, so as to prevent the reaction gas from carrying away the small bubble solution.

[0060] The sleeve 222 of the embodiment of the present application is a cylindrical structure and is coaxially arranged with the heat exchanger 21. The accommodating chamber 2111 is also a cylindrical chamber. If the drainage tube 4 extends in the axial direction facing the heat exchanger 21, the reaction solution will be sprayed to the outer periphery of the sleeve 222 and flow into the first gap 7 along both sides of the outer periphery of the sleeve 222. In this way, spiral turbulence will not be formed, which will affect the gas-liquid separation efficiency.

[0061] If the detection body 22 includes a liquid level sensor 221 and a sleeve 222 , the sleeve 222 is cylindrical, and the detection rod of the liquid level sensor 221 can be square or cylindrical; if the detection body 22 includes a liquid level sensor 221 , the detection rod of the liquid level sensor 221 is cylindrical.

[0062] Optionally, the first gap 7 is an annular space, the volume of which should be smaller than the volume flowing from the drainage tube 4 into the first gap 7. In this way, the reaction solution entering the first gap 7 will increase its flow rate due to its smaller volume, and will also gain an acceleration, forming turbulence, which is beneficial to gas-liquid separation.

[0063] If the space of the first gap 7 is large, the surface area of ​​gas-liquid separation will be large, and the separation effect will be good; however, if the space is too large, the reaction solution will quickly form a laminar flow, which is not conducive to gas-liquid separation; however, if the space is too small, the surface area of ​​gas-liquid separation will be reduced, which is also not conducive to gas-liquid separation. Therefore, in the embodiment of the present application, the width of the first gap 7 can be 0.5mm-0.75mm, that is, the distance between the outer surface of the sleeve 222 and the inner peripheral wall of the accommodating chamber 2111 can be 0.5mm-0.75mm, and the height between the end of the drainage tube 4 connected to the first gap 7 and the bottom of the first gap 7 can be 130mm. In this way, the volume of the reaction material flowing into the first gap 7 can be less than the volume of the reaction material flowing into the first gap 7 through the drainage tube 4.

[0064] like Figure 8 As shown, Figure 8 In the figure, the upper portion of the V-shape is the reaction gas, and the lower portion is the reaction solution. According to the principles of fluid mechanics, the reaction liquid flowing between the outer surface of the sleeve 222 and the inner surface of the accommodating chamber 2111 has a viscous particle velocity of zero on both walls. This forms a triangle with the reaction solution flowing in the middle, forming a V-shape with the two walls. Furthermore, the greater the flow rate and the greater the viscosity of the reaction solution, the deeper the bottom of the V-shape and the larger the surface area.

[0065] Therefore, in the embodiment of the present application, a first gap 7 is formed between the sleeve 222 and the accommodating chamber 2111, which increases the intensity of the turbulence when the reaction solution enters the first gap 7, the flow rate becomes faster, the viscosity of the reaction solution becomes larger, and the separation area is large enough to achieve complete separation of gas and liquid.

[0066] Optionally, the drainage tube 4 is set slightly higher than the center of the heat exchange body 211 in the axial direction, which may be higher than 3 mm, or even 4 mm. The setting position of the drainage tube 4 can be adjusted according to actual conditions.

[0067] As an embodiment, a plug-in slot is provided at one end of the bottom of the heat exchange body 211, and the plug-in slot is connected to the first gap 7. After the reaction solution enters the first gap 7, it can flow out through the plug-in slot. The separation device also includes a solution outlet seat 3, and a part of the solution outlet seat 3 is inserted into the plug-in slot. The channel in the solution outlet seat 3 can guide the reaction solution to flow out. The reaction solution in the first gap 7 flows downward in a spiral turbulent flow. By setting the solution outlet seat 3, the reaction solution is gathered at the position of the solution outlet seat 3, so that the reaction solution can flow out smoothly, thereby ensuring the continuity of gas-liquid separation.

[0068] Optionally, the solution outlet seat 3 is provided with a plug-in section, which is inserted into the plug-in slot, and the rest of the solution outlet seat 3 is placed outside the plug-in slot. The plug-in section is sealed and connected to the heat exchange body 211. During actual use, different sealing structures can be used according to the reaction temperature. For example, when the reaction temperature is below 150°C, polytetrafluoroethylene, polyetheretherketone, etc. can be used for sealing. In the range of 150°C-300°C, since it exceeds the temperature range that conventional seals can withstand, a ball head seal is used, which can withstand higher temperatures and is easy to load and unload. When the temperature is above 300°C, a spinal canal seal is used.

[0069] like Figure 2 、 4 As shown in Figure 6, as an embodiment, the outer periphery of the heat exchange body 211 is provided with a jacket 6 at intervals. The jacket 6 can be made of plastic to reduce costs, or other materials. Insulating material is filled between the jacket 6 and the outer surface of the heat exchange body 211 to insulate the heat exchange body 211.

[0070] like Figure 3 and 4 As shown, as an embodiment, the separation device includes an outlet pipe 5, the inlet of the outlet pipe 5 is connected to the first gap 7, and the outlet pipe 5 is used to guide the reaction gas to the gas collecting device outside the separation device to prevent the reaction gas from exploding in the air.

[0071] Optionally, the air outlet pipe 5 is arranged close to the top of the heat exchange body 211 .

[0072] Optionally, a first fixing device and a second fixing device are respectively provided at the upper and lower ends of the separation device, the first fixing device is clamped on the outer periphery of the separation device, and the second fixing device is clamped on the outer periphery of the solution outlet seat 3, and the first fixing device and the second fixing device are both fixedly connected to an external wall or other device to ensure the stability of the separation device.

[0074] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto.
