Description

Technical Field

[0001] The present application relates to the technical field of test devices, and in particular to a gas-liquid reaction device. Background Art

[0002] In the gas-liquid reaction experiment, the properties of the gas-liquid reaction are measured, for example, the diffusion coefficient of the gas-liquid, solubility, reaction kinetics and other properties are measured. In the experimental device used in the prior art, the inlet of the liquid reaction tube is sealed with a blade ring. This method has two unsolvable problems: 1. If the shrinking force of the blade ring is small, the sealing effect will be reduced and it will not be able to withstand high-pressure sealing; 2. If the shrinking force of the blade ring is large, the tube mouth of the liquid reaction tube, which is already prone to deformation and damage, will be completely closed or damaged, causing the equipment to completely fail. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a gas-liquid reaction device for ensuring the reliability of the sealed connection of the liquid reaction tube, so as to improve the accuracy of the test results in the gas-liquid reaction experiment.

[0004] The present application provides a gas-liquid reaction device, comprising: a heat jacket assembly, which defines a first cavity inside; a heating body assembly, which is arranged in the first cavity, the heating body assembly is used to connect a hot and cold device, and defines a second cavity inside; a gas-liquid reaction assembly, which is arranged in the second cavity, the gas-liquid reaction assembly includes a gas reaction tube and a liquid reaction tube arranged in the gas reaction tube; a sealing assembly, which includes a shell, a sealing connection assembly arranged in the shell, and a pressure-resistant bushing arranged in the shell, the sealing connection assembly is used to seal the inlet of the liquid reaction tube with the liquid supply pipeline, and the pressure-resistant bushing is supported on the inner wall surface of the inlet of the liquid reaction tube.

[0005] The gas-liquid reaction device provided in the embodiment of the present application includes: a heat jacket assembly, a heating body assembly, a gas-liquid reaction assembly and a preheating tube assembly, wherein the gas-liquid reaction assembly includes a gas reaction tube and a liquid reaction tube, the liquid reaction tube is arranged in the gas reaction tube, the liquid reaction tube is used for the circulation of the liquid to be reacted, the gas reaction tube is used for the circulation of the gas to be reacted, and the gas in the gas reaction tube can enter the liquid reaction tube through the tube wall of the liquid reaction tube. When the gas enters the liquid reaction tube from the gas reaction tube, the gas can be dissolved in the liquid so that a reaction can occur. The sealing assembly includes a shell, a sealing connection assembly arranged in the shell, and a pressure-resistant bushing arranged in the shell. Specifically, the outlet of the liquid supply pipe and the inlet of the liquid reaction tube are both located in the shell. The sealing connection assembly is connected to the outlet of the liquid supply pipe and the inlet of the liquid reaction tube. At the same time, a pressure-resistant bushing is arranged inside the inlet of the liquid reaction tube. The outer peripheral side of the pressure-resistant bushing is tightly abutted against the inner wall surface of the liquid reaction tube. When the liquid enters the liquid reaction tube after being preheated through the liquid supply pipe, on the one hand, the sealing connection assembly can ensure the sealing of the outlet of the liquid supply pipe and the inlet of the liquid reaction tube. At the same time, when the sealing connection assembly applies high pressure to the liquid reaction tube, the pressure-resistant bushing bears this part of the pressure, thereby preventing the liquid reaction tube from being deformed or even broken under high pressure. Through the sealing connection assembly and the pressure-resistant bushing of the sealing assembly, the sealing connection assembly obtains sufficient pressure to make the outlet of the liquid supply pipe and the inlet of the liquid reaction tube ideally sealed under high pressure, and at the same time, the pressure-resistant bushing ensures that the liquid reaction tube will not be damaged under high pressure.

[0006] It should be noted that the pressure-resistant bushing is a hard tube body with a through hole. On the one hand, the pressure-resistant bushing has a certain hardness and can withstand the high pressure applied to the liquid reaction tube by the sealing connection component. On the other hand, because the pressure-resistant bushing has a through hole, the through hole is connected to the liquid reaction tube, thereby ensuring that the liquid can smoothly pass through the pressure-resistant bushing into the liquid reaction tube.

[0007] A heat jacket assembly is also provided on the outside of the heating body assembly. Specifically, a first cavity is defined inside the heat jacket assembly, and the heating body assembly is located in the first cavity. The heat jacket assembly can be used to keep the heating body assembly warm and insulated, thereby preventing the room temperature from affecting the gas-liquid reaction experiment during the gas-liquid reaction experiment. At the same time, the heat jacket assembly can also protect the operator, preventing the operator from directly touching the heating body assembly and causing scalding accidents.

[0008] It should be noted that the heating and cooling device can be an all-in-one heating and cooling machine, which controls the temperature in the second cavity of the heating body assembly to maintain a constant temperature according to the ambient temperature required for the gas-liquid reaction experiment.

[0009] In a possible implementation, the sealing connection assembly includes: a flexible sealing sleeve, which is sleeved on the outer peripheral side of the inlet of the liquid reaction tube; a flexible sealing ring, which is sleeved on the outer peripheral side of the flexible sealing sleeve; a sealing pressure block, which is located above the flexible sealing ring and is arranged around the outer peripheral side of the flexible sealing sleeve, and the shell is suitable for pressing the flexible sealing ring downward through the sealing pressure block, so that the flexible sealing ring and the pressure-resistant bushing cooperate to form a sealing structure, which is sealed and connected to the outlet of the liquid preheating coil and the inlet of the liquid reaction tube.

[0010] In the above implementation process, the sealing connection component includes a flexible sealing sleeve, a flexible sealing ring and a sealing block, wherein the flexible sealing sleeve is a cylinder with a through hole and is arranged around the outer peripheral side of the inlet of the liquid reaction tube, the flexible sealing ring is annular and is arranged around the outer peripheral side of the flexible sealing sleeve, the sealing block is located above the flexible sealing ring and is arranged around the partial outer peripheral side of the flexible sealing sleeve, the shell applies pressure to the sealing block toward the flexible sealing ring, when the sealing block squeezes the flexible sealing ring downward, the closed sealing space in the shell makes the flexible sealing ring can only squeeze the flexible sealing sleeve inward, and the flexible sealing sleeve squeezes the liquid reaction tube inward, when the liquid reaction tube is about to deform and rupture inward, the deformation pressure is borne by the pressure-resistant bushing, so that the sealing connection component obtains sufficient pressure to make it seal the outlet of the liquid preheating coil and the inlet of the liquid reaction tube under high pressure, and at the same time the pressure-resistant bushing ensures that the liquid reaction tube will not be damaged under high pressure.

[0011] It should be noted that the flexible sealing sleeve may be made of polytetrafluoroethylene material.

[0012] In a possible implementation, the gas-liquid reaction device also includes: a preheating tube assembly, which is arranged in the second cavity, and the preheating tube assembly is respectively connected to the gas reaction tube and the liquid reaction tube, and is used to adjust the temperature of the gas in the gas reaction tube and the temperature of the liquid in the liquid reaction tube, and make the temperature of the gas entering the gas reaction tube and the temperature of the liquid entering the liquid reaction tube the same.

[0013] In the above implementation process, the preheating tube assembly is connected with both the gas reaction tube and the liquid reaction tube. Before the gas and liquid enter the gas reaction tube and the liquid reaction tube for reaction respectively, the gas and liquid first enter the preheating tube assembly respectively, and then enter the gas reaction tube and the liquid reaction tube respectively after being preheated by the preheating tube assembly. The temperature of the gas and liquid after preheating is the same, thereby ensuring that the temperature of the gas and liquid before starting the reaction is consistent. At the same time, the gas-liquid reaction assembly and the preheating tube assembly are both located in the second cavity defined by the heating body assembly. The heating body assembly is connected with the cold and hot device, and the temperature in the second cavity is ensured to remain unchanged by the cold and hot device, thereby further ensuring that the temperature of the environment in which the gas and liquid in the gas-liquid reaction assembly are located during the reaction process remains in a constant temperature state. Through the technical solution of the present application, the temperature of the gas and liquid can be ensured to be consistent before the gas and liquid start to react. At the same time, during the reaction of the gas and liquid, the temperature of the environment is also ensured to be in a constant temperature state, thereby avoiding the influence of temperature changes on the test results of the gas-liquid reaction experiment, so that the accuracy of the test results is improved.

[0014] In one possible implementation, the preheating tube assembly includes: a gas preheating coil and a liquid preheating coil, the gas preheating coil is arranged between the gas supply pipe and the gas reaction tube, and is used to preheat the gas before entering the gas reaction tube; the liquid preheating coil is arranged between the liquid supply pipe and the liquid reaction tube, and is used to preheat the liquid before entering the liquid reaction tube.

[0015] In the above implementation process, the preheating tube assembly includes a gas preheating coil and a liquid preheating coil that are independent of each other. The gas preheating coil is arranged between the gas supply pipeline and the gas reaction tube, and the gas supply pipeline and the gas reaction tube are connected. The gas in the gas supply pipeline flows to the gas preheating coil, and the gas flows to the gas reaction tube after being preheated by the gas preheating coil. At the same time, the liquid preheating coil is arranged between the liquid supply pipeline and the liquid reaction tube and is connected to the liquid supply pipeline and the liquid reaction tube. The liquid in the liquid supply device flows to the liquid preheating coil, and the liquid flows to the liquid reaction tube after being preheated by the liquid preheating coil. The preheated gas and liquid react again. The gas preheating coil and the liquid preheating coil are used to preheat the gas and liquid respectively. The inlets of the gas preheating coil and the liquid preheating coil are connected to the gas supply device and the liquid supply pipeline respectively, and there is no contact between them. Therefore, the volume of the gas in the gas preheating coil and the liquid in the liquid preheating coil does not increase the volume of the gas and liquid participating in the reaction, and therefore will not affect the reaction speed of the system.

[0016] It should be noted that both the gas preheating coil and the liquid preheating coil are disc-shaped structures, that is, formed by a straight pipe through spiral winding. In this way, the volume of the gas preheating coil and the liquid preheating coil can be expanded within a limited space, thereby facilitating the heating of more gas and liquid.

[0017] In a possible implementation, the liquid reaction tube includes: a fluorine-containing polymer thin-wall tube; and / or the gas reaction tube includes: a stainless steel tube.

[0018] In the above implementation process, the liquid reaction tube can be a fluorine-containing polymer thin-walled tube, and the gas reaction tube can be a stainless steel tube. The liquid reaction tube is arranged inside the gas reaction tube. Since the capillaries on the fluorine-containing polymer thin-walled tube allow external gas to enter while the liquid will not seep out, the gas in the gas reaction tube can dissolve and diffuse in the liquid in the liquid reaction tube. After the gas-liquid reaction experiment is completed, it is convenient to separate and recover the gas and liquid.

[0019] In a possible implementation manner, the gas reaction tube and the liquid reaction tube are spirally shaped, and the liquid reaction tube runs through the gas reaction tube.

[0020] In the above implementation process, the liquid reaction tube and the gas reaction tube are spiral, and the liquid reaction tube runs through the gas reaction tube, so that the volume of the liquid and gas reaction can be expanded in a limited space and sufficient reaction time can be ensured for the liquid and gas.

[0021] In a possible implementation, the gas-liquid reaction device further includes: a support assembly, which is disposed in the second cavity, and the gas-liquid reaction assembly and the preheating tube assembly are both fixedly connected to the support assembly.

[0022] In a possible implementation, the support assembly includes a support frame and an arc-shaped support plate arranged on the support frame, the preheating tube assembly is arranged on the top of the support frame, and the gas-liquid reaction assembly is arranged on the arc-shaped support plate; wherein, the support frame is also provided with a first longitudinal beam and a second longitudinal beam, and the first longitudinal beam and the second longitudinal beam are arranged above the gas-liquid reaction assembly at intervals.

[0023] In the above implementation process, the support frame and the arc support plate respectively support and fix the preheating tube assembly and the gas-liquid reaction assembly, ensuring the stability of the installation and fixation of the preheating tube assembly and the gas-liquid reaction assembly, and a frame structure for protecting the gas-liquid reaction assembly can be formed between the first longitudinal beam and the second longitudinal beam and the support frame, further ensuring the safety of the use of the gas-liquid reaction assembly.

[0024] In a possible implementation, the thermal jacket assembly is a thermal insulation component.

[0025] In the above implementation process, the heat jacket component is a heat insulating component, so it can prevent heat exchange between the gas-liquid reaction component and the external environment, so that the temperature inside the heat jacket component can be maintained within a preset temperature.

[0026] In a possible implementation, a fixed foot is provided at the bottom of the heating body assembly, and a heat insulation pad is provided at the bottom of the fixed foot.

[0027] In the above implementation process, the fixed legs serve to support and fix the heating body assembly, and the thermal insulation pad further serves to block heat transfer, thereby helping to further improve the stability of the gas-liquid reaction in the gas-liquid reaction assembly in the thermal jacket assembly.

DETAILED DESCRIPTION

[0034] 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.

[0035] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and 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 cannot be understood as indicating or implying relative importance.

[0036] First, please refer to Figure 1 , Figure 2 and Figure 3 The gas-liquid reaction device 100 provided in the embodiment of the present application includes: a heat jacket assembly 1, a heating body assembly 2, a gas-liquid reaction assembly 3 and a sealing assembly. Among them, the gas-liquid reaction assembly 3 includes a gas reaction tube 301 and a liquid reaction tube 302, the liquid reaction tube 302 is arranged in the gas reaction tube 301, the liquid reaction tube 302 is used for the liquid to be reacted to circulate, the gas reaction tube 301 is used for the gas to be reacted to circulate, and the gas in the gas reaction tube 301 can enter the liquid reaction tube 302 through the tube wall of the liquid reaction tube 302. When the gas enters the liquid reaction tube 302 from the gas reaction tube 301, the gas can be dissolved in the liquid to react. The sealing assembly includes a shell 5, a sealing connection assembly 6 arranged in the shell 5, and a pressure-resistant bushing 7 arranged in the shell 5. The sealing connection assembly 6 is used to seal and connect the outlet of the liquid supply pipeline and the inlet of the liquid reaction tube 302, and the pressure-resistant bushing 7 is used to support the inner wall surface of the inlet of the liquid reaction tube 302. The sealing assembly includes a shell 5, a sealing connection assembly 6 arranged in the shell 5 and a pressure-resistant bushing 7 arranged in the shell 5. Specifically, the sealing connection assembly 6 is connected to the outlet of the liquid supply pipeline and the inlet of the liquid reaction tube 302. At the same time, a pressure-resistant bushing 7 is arranged inside the inlet of the liquid reaction tube 302. The outer peripheral side of the pressure-resistant bushing 7 is tightly abutted against the inner wall surface of the liquid reaction tube 302. When the liquid enters the liquid reaction tube 302 after being preheated through the liquid supply pipeline, on the one hand, the sealing connection assembly 6 can ensure the sealing of the outlet of the liquid supply pipeline and the inlet of the liquid reaction tube 302. At the same time, when the sealing connection assembly 6 applies high pressure to the liquid reaction tube 302, the pressure-resistant bushing 7 bears this part of the pressure, thereby preventing the liquid reaction tube 302 from deforming or even rupturing under high pressure. Through the sealing connection component 6 and the pressure-resistant bushing 7 of the sealing component, the sealing connection component 6 obtains sufficient pressure to make the outlet of the liquid supply pipeline and the inlet of the liquid reaction tube 302 ideally sealed under high pressure. At the same time, the pressure-resistant bushing 7 ensures that the liquid reaction tube 302 will not be damaged under high pressure.

[0037] It should be noted that the pressure-resistant bushing 7 is a hard tube body with a through hole. On the one hand, the pressure-resistant bushing 7 has a certain hardness and can withstand the high pressure applied to the liquid reaction tube 302 by the sealing connection component 6. On the other hand, because the pressure-resistant bushing 7 has a through hole, the through hole is connected to the liquid reaction tube 302, thereby ensuring that the liquid can smoothly pass through the pressure-resistant bushing 7 into the liquid reaction tube 302.

[0038] In addition, a heat jacket assembly 1 is also provided on the outside of the heating body assembly 2. Specifically, a first cavity is defined inside the heat jacket assembly 1, and the heating body assembly 2 is located in the first cavity. The heat jacket assembly 1 can be used to keep the heating body assembly 2 warm and insulated, thereby preventing the room temperature from affecting the gas-liquid reaction experiment during the gas-liquid reaction experiment. At the same time, it can also protect the operator and prevent the operator from directly touching the heating body assembly 2 and causing scalding accidents.

[0039] It should be noted that the heating and cooling device can be an integrated heating and cooling machine, which controls the temperature in the second cavity 201 of the heating body assembly 2 to maintain a constant temperature according to the ambient temperature required for the gas-liquid reaction experiment.

[0040] like Figure 3 As shown, in a possible implementation, the sealing connection assembly 6 includes: a flexible sealing sleeve 601, which is sleeved on the outer peripheral side of the inlet of the liquid reaction tube 302; a flexible sealing ring 602, which is sleeved on the outer peripheral side of the flexible sealing sleeve 601; a sealing pressure block 603, which is located above the flexible sealing ring 602 and is surrounded by the outer peripheral side of the flexible sealing sleeve 601, and the shell 5 is suitable for squeezing the flexible sealing ring 602 downward through the sealing pressure block 603, so that the flexible sealing ring 602 and the pressure-resistant bushing 7 cooperate to seal and connect the outlet of the liquid preheating coil 402 and the inlet of the liquid reaction tube 302.

[0041] In the above implementation process, the sealing connection assembly 6 includes a flexible sealing sleeve 601, a flexible sealing ring 602 and a sealing pressing block 603, wherein the flexible sealing sleeve 601 is a cylinder with a through hole and is arranged around the outer peripheral side of the inlet of the liquid reaction tube 302, the flexible sealing ring 602 is annular and is arranged around the outer peripheral side of the flexible sealing sleeve 601, and the sealing pressing block 603 is located above the flexible sealing ring 602 and is arranged around the partial outer peripheral side of the flexible sealing sleeve 601. The housing 5 applies pressure to the sealing pressing block 603 toward the flexible sealing ring 602, and the sealing pressing block 603 is pressed against the flexible sealing ring 602. When the flexible sealing ring 602 is pressed downward, the sealed space in the housing 5 allows the flexible sealing ring 602 to only press the flexible sealing sleeve 601 inward, and the flexible sealing sleeve 601 presses the liquid reaction tube 302 inward. When the liquid reaction tube 302 is about to deform and rupture inward, the deformation pressure is borne by the pressure-resistant bushing 7. In this way, the sealing connection assembly 6 is provided with sufficient pressure to seal the outlet of the liquid preheating coil 402 and the inlet of the liquid reaction tube 302 under high pressure, and at the same time, the pressure-resistant bushing 7 ensures that the liquid reaction tube 302 will not be damaged under high pressure.

[0042] It should be noted that the flexible sealing sleeve 601 may be made of polytetrafluoroethylene material.

[0043] like Figure 3 As shown, in a possible implementation, the gas-liquid reaction device 100 further includes: a preheating tube assembly 4, which is arranged in the second cavity, and the preheating tube assembly 4 is respectively connected to the gas reaction tube 301 and the liquid reaction tube 302, and is used to adjust the temperature of the gas in the gas reaction tube 301 and the temperature of the liquid in the liquid reaction tube 302, and make the temperature of the gas entering the gas reaction tube 301 and the temperature of the liquid entering the liquid reaction tube 302 the same.

[0044] The preheating tube assembly 4 is connected to both the gas reaction tube 301 and the liquid reaction tube 302. Before the gas and the liquid enter the gas reaction tube 301 and the liquid reaction tube 302 for reaction, the gas and the liquid first enter the preheating tube assembly 4, and then enter the gas reaction tube 301 and the liquid reaction tube 302 respectively after being preheated by the preheating tube assembly 4. The temperature of the gas and the liquid after preheating is the same, thereby ensuring that the temperature of the gas and the liquid before the reaction starts is consistent. At the same time, the gas-liquid reaction assembly 3 and the preheating tube assembly 4 are both located in the second cavity 201 defined by the heating body assembly 2. The heating body assembly 2 is connected to the hot and cold device, and the temperature in the second cavity 201 is maintained unchanged by the hot and cold device and the heat jacket assembly 1, thereby further ensuring that the temperature of the environment in which the gas and liquid in the gas-liquid reaction assembly 3 are located during the reaction process remains constant. Through the technical solution of the present application, the temperature of the gas and liquid can be ensured to be consistent before the gas and liquid start to react. At the same time, during the reaction of the gas and liquid, the temperature of the environment is also ensured to be constant, thereby avoiding the influence of temperature changes on the test results of the gas-liquid reaction experiment, and improving the accuracy of the test results.

[0045] like Figure 1 Shown and Figure 3 As shown, in a possible implementation, the preheating tube assembly 4 includes: a gas preheating coil 401 and a liquid preheating coil 402. The gas preheating coil 401 is arranged between the gas supply device and the gas reaction tube 301, and is respectively connected to the gas supply device and the gas reaction tube 301, and is used to preheat the gas before entering the gas reaction tube 301; the liquid preheating coil 402 is arranged between the liquid supply device and the liquid reaction tube 302, and is respectively connected to the liquid supply device and the liquid reaction tube 302, and is used to preheat the liquid before entering the liquid reaction tube 302.

[0046] In the above implementation process, the preheating tube assembly 4 includes a gas preheating coil 401 and a liquid preheating coil 402 which are independent of each other. The gas preheating coil 401 is arranged between the gas supply device and the gas reaction tube 301 and is connected with the gas supply device and the gas reaction tube 301. The gas in the gas supply device flows to the gas preheating coil 401. After being preheated by the gas preheating coil 401, the gas flows to the gas reaction tube 301. At the same time, the liquid preheating coil 402 is arranged between the liquid supply device and the liquid reaction tube 302 and is connected with the liquid supply device and the liquid reaction tube 302. The liquid in the liquid supply device flows to the liquid preheating coil 402. After being preheated by the liquid preheating coil 402, the liquid flows to the liquid reaction tube 302. The preheated gas and liquid react again. The gas preheating coil 401 and the liquid preheating coil 402 are used to preheat the gas and liquid respectively. The inlets of the gas preheating coil 401 and the liquid preheating coil 402 are connected to the gas supply device and the liquid supply device respectively, and there is no contact between them. Therefore, the volume of the gas in the gas preheating coil 401 and the liquid in the liquid preheating coil 402 does not increase the volume of gas and liquid participating in the reaction, and therefore will not affect the reaction speed of the system.

[0047] It should be noted that both the gas preheating coil 401 and the liquid preheating coil 402 are disc-shaped structures, that is, formed by a straight pipe through spiral winding. In this way, the volume of the gas preheating coil 401 and the liquid preheating coil 402 can be expanded within a limited space, thereby facilitating the heating of more gas and liquid.

[0048] In a possible implementation, the liquid reaction tube 302 includes: a fluorine-containing polymer thin-wall tube; and / or the gas reaction tube 301 includes: a stainless steel tube.

[0049] In the above implementation process, the liquid reaction tube 302 can be a fluorine-containing polymer thin-walled tube, and the gas reaction tube 301 can be a stainless steel tube. The liquid reaction tube 302 is arranged inside the gas reaction tube 301. Since the capillaries on the fluorine-containing polymer thin-walled tube allow external gas to enter while the liquid will not seep out, the gas in the gas reaction tube 301 can dissolve and diffuse in the liquid in the liquid reaction tube 302. After the gas-liquid reaction experiment is completed, it is convenient to separate and recover the gas and liquid.

[0050] In a possible implementation, the gas reaction tube 301 and the liquid reaction tube 302 are spirally shaped, and the liquid reaction tube 302 runs through the gas reaction tube 301 .

[0051] In the above implementation process, the gas reaction tube 301 and the liquid reaction tube 302 are spiral, and the liquid reaction tube 302 runs through the gas reaction tube 301, so that the volume of the liquid and gas reaction can be expanded in a limited space and sufficient reaction time can be ensured for the liquid and gas.

[0054] In the above implementation process, the support frame 801 and the arc support plate 802 respectively support and fix the preheating tube assembly and the gas-liquid reaction assembly 3, ensuring the stability of the installation and fixation of the preheating tube assembly and the gas-liquid reaction assembly 3, and the first longitudinal beam 803 and the second longitudinal beam 804 and the support frame 801 can form a frame structure for protecting the gas-liquid reaction assembly 3, further ensuring the safety of the use of the gas-liquid reaction assembly 3.

[0055] In a possible implementation, the thermal jacket assembly 1 is a thermal insulation component.

[0056] In the above implementation process, the heat jacket component 1 is a heat insulating component, so it can prevent heat exchange between the gas-liquid reaction component 3 and the external environment, so that the temperature inside the heat jacket component 1 can be maintained within a preset temperature.
