Description

Technical Field

[0001] The present invention belongs to the technical field of gas-liquid separation, and in particular relates to a compact gas-liquid separation device, system and separation method. Background Art

[0002] Existing gas-liquid separation devices are all designed for rated working conditions, including gravity type, cyclone type, filtration type, etc. If a large fluctuation occurs in the working condition, the separation effect will be greatly reduced. At the same time, there are also devices that use multiple technologies that overlap with each other, such as gravity type and filtration type, and their equipment volume and cost are increased. Therefore, the present invention adopts a spiral coil structure and a gas-liquid mixture flow channel cooling and strong interference structure to ensure the gas-liquid separation effect under fluctuating working conditions through the dual effects of centrifugation and cooling. At the same time, the strong interference parts collide with the gas and liquid. Due to the different densities of gas and liquid, the difference in gas-liquid flow rate is reduced, which promotes further separation of gas and liquid. Because this part of the structure is closely related to the gas-liquid density, it has little to do with the fluctuation of working conditions and can be applied to separation scenarios with a wide range of fluctuating working conditions.

[0003] At the same time, the gas-liquid separation device is used in different processes and sections in various fields. With the fluctuation of the production capacity of the process, the gas-liquid separation device has high requirements for adaptability to large fluctuations, such as the PEM electrolysis hydrogen production system. With the development of hydrogen energy technology, the consumption of green hydrogen and green electricity has received widespread attention in the industry. The quality of green hydrogen products is closely related to the separation effect of the gas-liquid separation device. At the same time, the fluctuation range of green electricity is much larger than that of the process / section in the traditional field. Therefore, the spiral coil structure and the cooling and strong interference structure of the gas-liquid mixture flow channel adopted in the present invention not only improve the gas-liquid separation effect under rated conditions, but also ensure the gas-liquid separation effect under large fluctuation conditions. It has a large scope of promotion in the future and is not limited to the electrolysis hydrogen production system.

[0004] The existing cyclone separation device is a dry gas-solid separation device that uses the centrifugal force generated by the high-speed rotation of the gas-solid mixture to separate the dust from the airflow. Since the centrifugal force on the particles is much greater than the gravity and inertia force, the separation efficiency is relatively high.

[0005] However, the movement of gas and solid particles in the cyclone separation device is very complex. There are tangential, radial and axial velocities at any point in the device, and they vary with the rotation radius. In actual operation, the appropriate gas velocity should be controlled. Experiments show that if the gas velocity is too low, the separation efficiency is not high. However, if the gas velocity is too high, eddy currents and back-mixing are likely to occur, which will also reduce the separation efficiency.

[0006] This technology is suitable for stable working conditions, but for fluctuating working conditions, the separation effect of the equipment itself can only be achieved under its rated working conditions. Summary of the invention

[0007] The object of the present invention is to provide a compact gas-liquid separation device, system and separation method to solve the problem that the prior art has low separation efficiency and is not suitable for fluctuating working conditions.

[0008] To achieve the above object, the present invention adopts the following technical solutions: In the first aspect, the present invention provides a compact gas-liquid separation device, comprising a gas-liquid separation container, a first gas-liquid separation cooling component and a second gas-liquid separation cooling component, the first gas-liquid separation cooling component is spirally arranged inside the gas-liquid separation container, a gas-liquid mixture inlet is arranged at the bottom of the gas-liquid separation container, the gas-liquid mixture inlet is connected to the gas-liquid separation cooling component, and the gas-liquid separation cooling is used for gas-liquid separation and cooling of the gas-liquid mixture; the second gas-liquid separation cooling component is arranged at the top of the gas-liquid separation container for secondary gas-liquid separation.

[0009] Furthermore, the gas-liquid separation container includes a cavity, a gas-liquid mixture inlet pipe and a liquid storage structure; the liquid storage structure is arranged at the bottom of the cavity, the gas-liquid mixture inlet pipe is connected to the gas-liquid mixture inlet, and the gas-liquid mixture inlet is located at the bottom of the cavity side.

[0010] Furthermore, the first gas-liquid separation cooling component includes a gas-liquid mixing spiral guide plate and a cooling component. The gas-liquid mixing spiral guide plate is fixedly installed on the inner wall of the cavity to form a spiral channel on the inner wall of the cavity. The cooling component is arranged along the spiral channel.

[0011] Furthermore, a liquid outlet pipe is provided at the bottom of the liquid storage structure.

[0012] Furthermore, a cooling liquid outlet pipe and a cooling liquid inlet pipe are provided on the outer side wall of the cavity, and the cooling liquid outlet pipe and the cooling liquid inlet pipe are respectively connected to two ends of the cooling component.

[0013] Furthermore, the cooling component includes a cooling coil and spiral thin fins. The cooling coil is spirally arranged in the spiral channel, and the spiral thin fins are spirally wound around the cooling coil.

[0014] Furthermore, the second gas-liquid separation cooling component includes a gas-liquid millimeter-level filter and a top head. The gas-liquid millimeter-level filter is arranged on the top of the cavity, and the top head is arranged on the outside of the gas-liquid millimeter-level filter and is sealed and connected to the cavity.

[0015] Furthermore, a gas outlet pipe is connected to the top cover.

[0016] In a second aspect, the present invention provides a compact gas-liquid separation system, comprising the compact gas-liquid separation device described above.

[0017] In a third aspect, the present invention provides a separation method of a compact gas-liquid separation device, comprising the following steps: The gas-liquid mixture enters vertically or tangentially from the gas-liquid mixture inlet pipe and enters the first gas-liquid separation cooling component in the container. The gas-liquid mixture flows from bottom to top along the spiral channel. Under the action of centrifugal force, the liquid is thrown out along the outer edge of the spiral channel to perform the first gas-liquid separation. At the same time, the gas-liquid mixture flows through the cooling coil and spiral thin fins for disturbance cooling. The gas continues to flow at a higher speed and is further cooled and separated by the second gas-liquid separation cooling component at the top. The separated gas is discharged from the gas outlet pipe, and the separated liquid flows to the liquid storage structure at the bottom and is then distributed from the liquid outlet pipe.

[0018] Compared with the prior art, the present invention has the following technical effects: The present invention adopts a spiral coil structure and a cooling and strong interference structure design for the gas-liquid mixture flow channel to improve the efficiency and effect of gas-liquid separation. The spiral coil not only serves as a cooling element, but also utilizes the principle of centrifugal force to achieve preliminary separation of the gas-liquid mixture as it flows along the spiral channel. When the gas-liquid mixture enters the spiral channel, due to the action of centrifugal force, the heavier liquid phase is thrown to the outer wall of the channel, while the lighter gas phase tends to remain in the center of the channel, thereby achieving two-phase separation of gas and liquid.

[0019] In order to further enhance the separation effect, the present invention adds a cooling structure in the spiral channel. This cooling structure effectively reduces the temperature of the gas-liquid mixture by circulating cooling liquid, so that the liquid quickly reaches or approaches the condensation point. In such a low temperature environment, the liquid phase is more likely to condense into droplets, thereby continuously separating from the gas phase during the flow process. The synergistic effect of this cooling and separation improves the efficiency of gas-liquid separation.

[0020] The cooling coil is used on the cooling liquid side, which not only increases the cooling area, but also reduces the local resistance loss on the cooling side and reduces the energy consumption on the cooling medium side. A gas-liquid mixing spiral guide plate is added on the gas-liquid two-phase side, which has the same rotation direction as the cooling coil on the coolant side, so that the gas-liquid two-phase flow liquid and the coolant are fully contacted, achieving rapid cooling.

[0021] Adding spiral thin fins to the cooling coil increases the contact area between the gas-liquid two-phase side and the coolant, increases the centrifugal force during the gas-liquid two-phase separation process, and at the same time improves the convection heat transfer coefficient and the cooling effect, thereby achieving efficient and rapid cooling of the gas-liquid two-phase.

[0022] In addition, the cooling coil of the present invention also acts as an interference element in the flow channel. These interference elements have a significant obstruction effect on the flowing liquid, slowing down its flow rate. Since the flow rates of gas and liquid are not synchronized, the gas phase can pass through the interference element more smoothly, while the liquid phase is blocked and retained, thereby further promoting the separation of the gas and liquid phases. The design of this strong interference structure not only enhances the effect of gas-liquid separation, but also improves the stability of the system.

[0023] After the gas-liquid mixture is initially separated and cooled in the spiral channel, the present invention adds a gas-liquid millimeter filter at the outlet terminal of the spiral channel. This filter acts as a secondary separation mechanism to further finely filter the gas-liquid mixture that has undergone initial separation. Due to the centrifugal force, the gas-liquid mixture has a higher tangential flow velocity when entering the filter, which significantly increases the flow resistance and collision force. In this environment of high flow resistance and high collision force, the residual tiny droplets are more effectively captured and separated, thereby further improving the effect of gas-liquid separation.

[0024] Since the gas-liquid circulation channel adopts a spiral structure, the flow change of the gas-liquid mixture has little effect on the separation effect. This feature makes the present invention more suitable for water electrolysis hydrogen production devices under fluctuating conditions. In the process of water electrolysis hydrogen production, due to the large-scale changes in power, the flow of the gas-liquid mixture will also fluctuate accordingly. However, the spiral coil structure and the gas-liquid mixture circulation channel design of the present invention can effectively cope with such flow changes, maintain a stable separation effect, and provide a strong guarantee for the efficient operation of the water electrolysis hydrogen production device.

[0028] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Example 1, please refer to Figure 1 The present invention provides a compact gas-liquid separation device, including a gas-liquid separation container, a first gas-liquid separation cooling component and a second gas-liquid separation cooling component. The first gas-liquid separation cooling component is spirally arranged inside the gas-liquid separation container. A gas-liquid mixture inlet is arranged at the bottom of the gas-liquid separation container. The gas-liquid mixture inlet is connected to the gas-liquid separation cooling component. The gas-liquid separation cooling is used for gas-liquid separation and cooling of the gas-liquid mixture. The second gas-liquid separation cooling component is arranged at the top of the gas-liquid separation container for secondary gas-liquid separation.

[0032] The present invention adopts a spiral coil structure and a cooling and strong interference structure for the gas-liquid mixture flow channel. It not only realizes the separation of gas and liquid during the flow process by means of the centrifugal force principle, but also adds a cooling structure to allow the liquid to quickly reach the condensation point, so that the liquid is continuously separated during the flow process. At the same time, interference parts are added to the flow channel, and the interference parts collide with the gas and liquid. Due to the different densities of gas and liquid, the rate at which the liquid is disturbed decreases faster than the liquid, making the gas and liquid flow rates asynchronous, thereby improving the effect of gas-liquid separation. Finally, a gas-liquid millimeter-level filter device is added to the outlet terminal of the gas-liquid mixture spiral channel. After the gas-liquid mixture with increased tangential flow rate due to centrifugal force enters, the flow resistance and collision force increase, further improving the separation effect. Because the gas-liquid flow channel is a spiral structure, the flow change of the gas-liquid mixture has little effect on the separation effect, and is more suitable for the working condition where the power of the water electrolysis hydrogen production device changes over a large range under fluctuating working conditions, causing changes in the flow rate of the gas-liquid mixture.

[0033] Embodiment 2, the present invention provides a compact gas-liquid separation device, specifically comprising: In this device, the gas outlet pipe 1, the top head 2, the bottom gas-liquid separation and liquid storage structure 7, the liquid outlet pipe 8, the gas-liquid mixing inlet pipe 9 and the cavity 11 constitute a gas-liquid separation container, wherein the bottom gas-liquid separation and liquid storage structure 7 can be a cylindrical or conical or special-shaped structure, and can be optimized according to the gas-liquid flow rate, gas-liquid separation index requirements and separation simulation effect.

[0034] In the device, the gas-liquid millimeter filter 3, the cooling liquid outlet pipe 4, the cooling coil 5, the cooling liquid inlet pipe 6, the gas-liquid mixing spiral guide plate 10 and the spiral thin fins 12 constitute a gas-liquid separation cooling component.

[0035] The gas-liquid separation container includes a cavity 11, a gas-liquid mixture inlet pipe 9 and a liquid storage structure 7; the liquid storage structure 7 is arranged at the bottom of the cavity 11, the gas-liquid mixture inlet pipe 9 is connected to the gas-liquid mixture inlet, and the gas-liquid mixture inlet is located at the bottom of the cavity 11 side.

[0036] The first gas-liquid separation cooling component includes a gas-liquid mixing spiral guide plate 10 and a cooling component. The gas-liquid mixing spiral guide plate 10 is fixedly installed on the inner wall of the cavity 11 to form a spiral channel on the inner wall of the cavity 11. The cooling component is arranged along the spiral channel.

[0037] A cooling liquid outlet pipe 4 and a cooling liquid inlet pipe 6 are provided on the outer side wall of the cavity 11 , and the cooling liquid outlet pipe 4 and the cooling liquid inlet pipe 6 are respectively connected to two ends of the cooling component.

[0038] The cooling component includes a cooling coil 5 and spiral thin fins 12 . The cooling coil 5 is spirally arranged in the spiral channel, and the spiral thin fins 12 are spirally wound around the cooling coil 5 .

[0039] The second gas-liquid separation cooling component includes a gas-liquid millimeter-level filter 3 and a top head 2. The gas-liquid millimeter-level filter 3 is arranged on the top of the cavity 11, and the top head 2 is arranged on the outside of the gas-liquid millimeter-level filter 3 and is sealed and connected to the cavity 11.

[0040] Gas-liquid separation container: As the main body of the entire device, the container is designed with a specific structure to support the gas-liquid separation process. A gas-liquid mixture inlet is provided at the bottom of the container to receive the gas-liquid mixture to be separated.

[0041] First gas-liquid separation cooling component: Gas-liquid mixing spiral guide plate: fixed on the inner wall of the container to form a spiral channel. This design uses the principle of centrifugal force to initially separate the gas-liquid mixture during the spiral flow process.

[0042] Cooling components: including cooling coils and spiral thin fins, which are arranged along the spiral channel. The cooling coils effectively reduce the temperature of the gas-liquid mixture by circulating the cooling liquid (such as cold water), prompting the liquid to quickly reach the condensation point and accelerate the condensation and separation of the droplets. The spiral thin fins increase the cooling area and improve the cooling efficiency.

[0043] Second gas-liquid separation cooling component: Gas-liquid millimeter filter: It is installed on the top of the container as a secondary separation mechanism. After the initial separation, the gas-liquid mixture enters the filter, where the flow resistance and collision force increase, further capturing and separating the remaining tiny droplets, achieving millimeter-level gas-liquid separation.

[0044] Top head: seals and connects the filter and the container to ensure the airtightness of the gas-liquid separation process. At the same time, the top head is connected to a gas outlet pipe to discharge the separated gas.

[0045] Liquid storage structure and outlet: located at the bottom of the container, used to collect the separated liquid and discharge it through the liquid outlet pipe.

[0046] Cooling liquid circulation system: Through the cooling liquid inlet pipe and outlet pipe, the cooling liquid in the cooling coil is circulated to continuously provide cooling effect.

[0047] Combining the centrifugal force generated by the spiral channel with the rapid cooling effect of the cooling member, the present invention can efficiently achieve gas-liquid separation. The spiral structure increases the flow path and interference of the gas-liquid mixture, causing the liquid to be disturbed and slowed down, and the gas-liquid flow rate is not synchronized, thereby improving the separation efficiency.

[0048] Due to the spiral structure of the gas-liquid flow channel, even if the flow rate of the gas-liquid mixture changes, the separation effect is less affected. This makes the device particularly suitable for working conditions in water electrolysis hydrogen production devices where the flow rate of the gas-liquid mixture fluctuates due to a wide range of power changes.

[0049] The gas-liquid millimeter-level filter installed on the top further improves the separation accuracy, ensures the purity of the gas after separation, and meets the needs of high-precision gas-liquid separation.

[0050] Through integrated design, the gas-liquid separation, cooling and filtration functions are integrated into a compact device, saving space and improving the integration and ease of use of the equipment.

[0051] In summary, the present invention achieves efficient, precise and adaptable gas-liquid separation through the innovative spiral coil structure and the cooling and strong interference design of the gas-liquid mixture flow channel. It is particularly suitable for water electrolysis hydrogen production devices under fluctuating operating conditions and has significant technical advantages and application prospects.

[0052] Embodiment 3, the present invention provides a compact gas-liquid separation system, including a compact gas-liquid separation device.

[0053] The core of the compact gas-liquid separation system provided by the present invention is a compact gas-liquid separation device with an innovative design.

[0054] The system uses the spiral channel design in the compact gas-liquid separation device and the centrifugal force principle to achieve preliminary separation of the gas-liquid mixture during the flow process. The spiral channel increases the flow path of the gas-liquid mixture, making it easier for the liquid to be separated due to the centrifugal force.

[0055] At the same time, the addition of cooling components can further improve the separation efficiency by lowering the temperature of the gas-liquid mixture and promoting rapid condensation of the liquid. The design of cooling coils and spiral thin fins increases the cooling area and ensures a fast and uniform cooling effect.

[0056] The gas-liquid millimeter filter in the system acts as a secondary separation mechanism, which can capture and separate the tiny droplets remaining after the initial separation. This design ensures the purity of the gas after separation and meets the needs of high-precision gas-liquid separation.

[0057] The sealed connection of the top head ensures the airtightness of the secondary separation process and prevents gas leakage and liquid contamination.

[0058] Due to the spiral structure of the gas-liquid flow channel, the system has strong adaptability to the flow changes of the gas-liquid mixture and can maintain a stable separation effect even in the case of flow fluctuations.

[0059] This adaptability makes the system particularly suitable for use in applications such as water electrolysis to produce hydrogen, where the flow rate of the gas-liquid mixture may fluctuate greatly due to power changes.

[0060] The design of the compact gas-liquid separation device integrates the gas-liquid separation, cooling and filtration functions in one compact unit. This design saves space and improves the integration and ease of use of the equipment.

[0061] The compactness of the system also makes it easy to install and maintain, reducing operating costs.

[0062] Through efficient and precise gas-liquid separation, the system can improve the efficiency and stability of subsequent processes. For example, in the process of water electrolysis to produce hydrogen, the pure gas output can improve the purity and yield of hydrogen.

[0063] The stability and adaptability of the system also ensure long-term reliability and durability, reducing downtime and maintenance costs.

[0064] In summary, the compact gas-liquid separation system provided by the present invention realizes efficient, accurate and adaptable gas-liquid separation through innovative design concepts and advanced technical means. The system not only improves the efficiency and purity of gas-liquid separation, but also enhances the stability and integration of the system, providing a reliable and efficient solution for related industrial fields.

[0065] Embodiment 4, the present invention provides a separation method of a compact gas-liquid separation device, comprising the following steps: The gas-liquid mixture enters vertically or tangentially from the gas-liquid mixture inlet pipe 9 and enters the first gas-liquid separation cooling component in the container. The gas-liquid mixture flows from bottom to top along the spiral channel. Under the action of centrifugal force, the liquid is thrown out along the outer edge of the spiral channel to perform the first gas-liquid separation. At the same time, the gas-liquid mixture flows through the cooling coil 5 and the spiral thin fins 12 for disturbance cooling. Specifically, Increase the disturbance resistance during high-speed gas-liquid mixed flow, improve the difference in gas and liquid flow rates, and promote gas-liquid separation; Increasing disturbance improves the cooling and heat exchange process, accelerates liquid condensation, and improves gas-liquid separation. Increase cooling, speed up liquid cooling, and improve gas-liquid separation effect.

[0066] The gas continues to flow at a higher speed and is further cooled and separated by the second gas-liquid separation cooling component at the top. The separated gas is discharged from the gas outlet pipe 1 , and the separated liquid flows to the liquid storage structure 7 at the bottom and is then distributed from the liquid outlet pipe 8 .

[0067] The gas-liquid mixture enters from the gas-liquid mixing inlet pipe 9, and the entry method is either vertical or tangential. The gas-liquid mixture entering the container flows from bottom to top along the gas-liquid mixing spiral guide plate 10. Because this structure is a spiral channel, centrifugal motion can be formed. Due to its high density, the liquid is thrown out along the outer edge of the gas-liquid mixing spiral guide plate 10 due to the action of centrifugal force, and the gas continues to flow to the top along the gas-liquid mixing spiral guide plate 10 with a certain tangential flow rate. The gas-liquid millimeter filter 3 at the top has a high tangential flow rate, which increases the flow resistance through the gas-liquid millimeter filter 3, and further performs gas-liquid separation. The separated gas is discharged from the gas outlet pipe 1, and most of the separated liquid flows along the cavity 11 to the bottom gas-liquid separation and liquid storage structure 7 due to the action of centrifugal force, and then is dispensed from the liquid outlet pipe 8. At the same time, a fluid cooling coil 5 is added in the middle of the gas-liquid mixing spiral guide plate 10, and a spiral thin fin 12 is added to the fluid cooling coil 5. Under the premise of the centrifugal force of the gas-liquid mixture, the cooling process and the disturbance of the fluid in the channel are increased, thereby further increasing the condensation of the liquid and the difference in gas-liquid flow rate, thereby increasing the gas-liquid separation effect.

[0068] In general, the device achieves efficient separation of gas-liquid mixed fluids under variable working conditions by increasing the centrifugal force of the gas-liquid mixture, enhancing cooling, disrupting the synchronization of gas-liquid flow rates, and increasing flow resistance by tangential flow rate.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
