[0027] The following is for reference Figure 1-2 The present invention relates to a gas-liquid separator suitable for a wide range of fluctuating operating conditions.

[0028] The first aspect of this utility model provides a gas-liquid separator suitable for a wide range of fluctuating operating conditions, which will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-2 As shown, a gas-liquid separator suitable for a wide range of fluctuating operating conditions includes a housing and a separation device 5 disposed within the receiving cavity. The housing has a receiving cavity, and the housing has an air outlet 1 and a liquid outlet 8 communicating with the receiving cavity. The separation device 5 includes an inlet pipe 4, a top plate 12, a bottom plate 15, multiple sets of rotating components, and multiple guide vanes 13. The inlet pipe 4 passes through the housing and is connected to the top plate 12. The top plate 12 and the bottom plate 15 are spaced apart. The rotating components are all rotatably disposed on the top plate 12 and the bottom plate 15, and are spaced apart. Each set of rotating components is connected to a guide vane 13, and the guide vanes 13 are all rotatable. Located between the top plate 12 and the bottom plate 15, the guide vanes 13 are spaced apart to form an openable first flow channel. A structural cavity is formed between the top plate 12, the bottom plate 15, and the multiple guide vanes 13. The structural cavity is connected to the air inlet pipe 4, and the size of the structural cavity is larger than the size of the air inlet pipe 4. A gas-liquid mixture is introduced into the structural cavity through the air inlet pipe 4. The gas-liquid mixture can be separated into gas and liquid in the structural cavity and push the guide vanes 13 to rotate outward. The rotary assembly can drive the guide vanes 13 to rotate inward. The gas and liquid obtained from the gas-liquid separation are introduced into the receiving cavity through the multiple first flow channels. The gas is discharged from the air outlet 1, and the liquid is discharged from the liquid outlet 8.

[0030] It should be noted that a pressurized gas-liquid mixture flows into the structural cavity through the inlet pipe 4. The size of the structural cavity is larger than that of the inlet pipe 4. The gas-liquid mixture increases in volume and decreases in velocity within the structural cavity. A portion of the liquid separates out by gravity and settles on the bottom plate 15. The settled liquid is then discharged through the first flow channel under the influence of airflow and accumulates at the bottom of the tank. The gas-liquid mixture that has undergone preliminary separation experiences increased flow velocity and volume expansion in the first flow channel. According to the law of conservation of energy, the increase in kinetic energy leads to a decrease in internal energy, i.e., a decrease in temperature, which helps the vapor in the gas phase to condense and precipitate, thus performing gas-liquid separation again. The rotary component can be any structure capable of automatic rotation. It can be driven by a motor or a spring. In this embodiment, preferably, the rotary component is equipped with a spring. The number of guide vanes 13 and the outlet angle can be set as needed to meet the gas-liquid separation effect within a wide operating range.

[0031] In order to enable the gas-liquid mixture to drive the guide vane 13 and achieve self-adaptation, in this embodiment, the guide vane 13 is plate-shaped or teardrop-shaped, one side wall of the guide vane 13 is connected to the rotary assembly, and the other side wall of the guide vane 13 is disposed between the top plate 12 and the bottom plate 15, rotating around the rotary assembly.

[0032] To ensure the stable operation of the separation device 5, in this embodiment, the rotary assembly includes a rotating shaft 9 and a spring. The rotating shaft 9 is rotatably mounted on the top plate 12 and the bottom plate 15. The guide vane 13 is connected to the rotating shaft 9. One end of the spring is connected to the rotating shaft 9, and the other end of the spring is connected to the bottom plate 15.

[0033] In order to reduce the size of the device and at the same time realize the connection between the components, in this embodiment, one end of the rotating shaft 9 is provided with a protrusion, which is located on the side of the top plate 12 away from the bottom plate 15, and the other end of the rotating shaft 9 is located on the side of the bottom plate 15 away from the top plate 12. The other end of the rotating shaft 9 is connected to one end of the spring.

[0034] To provide better rotational force, in this embodiment, the spring is a planar spiral spring 10. The planar spiral spring 10 is disposed on the side of the base plate 15 away from the top plate 12. The planar spiral spring 10 is sleeved on the rotating shaft 9. The inner end of the planar spiral spring 10 is connected to the rotating shaft 9, and the outer end of the planar spiral spring 10 is hinged to the base plate 15 through a shaft pin.

[0035] To simplify the structure and facilitate the connection between components, in this embodiment, the top plate 12 is provided with a plurality of first connecting holes arranged in a ring, and the bottom plate 15 is provided with a plurality of second connecting holes arranged in a ring. The rotating assembly passes through the first connecting holes and the second connecting holes.

[0036] In order to better achieve gas-liquid separation and remove the separated gas and liquid, in this embodiment, the shell includes an upper end cap 2, a lower end cap 7 and a shell cylinder 6. The upper end cap 2 is provided with the gas outlet 1 and is sealed at the upper end of the shell cylinder 6. The lower end cap 7 is sealed at the lower end of the shell cylinder 6 and is provided with the liquid drain port 8. The shell cylinder 6 is provided with the air inlet pipe 4.

[0037] To further improve separation efficiency, in this embodiment, a plurality of baffles 14 are provided between the top plate 12 and the bottom plate 15. The baffles 14 are wavy and are arranged sequentially. The gaps between the baffles 14 form a second flow channel, and the second flow channel is connected to the first flow channel.

[0038] To further improve the separation efficiency, this embodiment also includes a demister 3, which is horizontally disposed inside the housing, such that the accommodating cavity is divided into a first cavity and a second cavity. The air inlet, the first flow channel and the liquid outlet 8 of the demister 3 are all connected to the first cavity, and the air outlet and the air outlet 1 of the demister 3 are both connected to the second cavity.

[0039] In one embodiment, the guide vane 13 is plate-shaped or teardrop-shaped, with one side wall of the guide vane 13 connected to the rotary assembly, and the other side wall of the guide vane 13 rotatably disposed between the top plate 12 and the bottom plate 15 around the rotary assembly. This allows the guide vane 13 to flexibly respond to the flow of the gas-liquid mixture, effectively adjust the size of the flow channel, thereby optimizing the gas-liquid separation effect. Simultaneously, it facilitates cleaning and maintenance, reducing the operating costs of the equipment.

[0040] In one embodiment, the rotary assembly includes a rotating shaft 9 and a spring. The rotating shaft 9 is rotatably mounted on the top plate 12 and the bottom plate 15. The guide vane 13 is connected to the rotating shaft 9. One end of the spring is connected to the rotating shaft 9, and the other end of the spring is connected to the bottom plate 15. It should be noted that the spring provides adjustment power for the guide vane 13, and the type of spring is not limited to helical springs, spiral springs, leaf springs, etc. The guide vane 13 can rotate outward when pushed by the gas-liquid mixture, while the spring provides a restoring force, allowing the guide vane 13 to rotate inward when the flow rate decreases. This maintains the stability and separation efficiency of the device.

[0041] In one embodiment, one end of the rotating shaft 9 has a protrusion located on the side of the top plate 12 away from the bottom plate 15, and the other end of the rotating shaft 9 is located on the side of the bottom plate 15 away from the top plate 12. The other end of the rotating shaft 9 is connected to one end of the spring. This makes the installation and disassembly of the rotating shaft 9 more convenient, while also enhancing its stability and improving the overall performance of the equipment.

[0042] In one embodiment, the spring is a planar spiral spring 10, which is disposed on the side of the base plate 15 away from the top plate 12. The planar spiral spring 10 is sleeved on the rotating shaft 9, with its inner end connected to the rotating shaft 9 and its outer end hinged to the base plate 15 via a pin. It should be noted that the planar spiral spring 10 has advantages such as small size, large energy storage, and stable force. Therefore, while simplifying the device, it can provide a stable rebound force when the guide vane 13 is subjected to external force, allowing the guide vane 13 to rotate smoothly, thereby maintaining the stability and separation efficiency of the flow channel.

[0043] In one embodiment, the top plate 12 has a plurality of first connecting holes arranged in a ring, and the bottom plate 15 has a plurality of second connecting holes arranged in a ring. The rotary assembly passes through the first connecting holes and the second connecting holes. This allows for more flexible installation of the rotary assembly, enabling adjustments to the layout and number of guide vanes 13 according to actual needs, thereby optimizing the gas-liquid separation effect.

[0044] In one embodiment, the housing includes an upper end cap 2, a lower end cap 7, and a shell cylinder 6. The upper end cap 2 is provided with the air outlet 1 and is located at the upper end of the shell cylinder 6. The lower end cap 7 is located at the lower end of the shell cylinder 6 and is provided with the liquid drain port 8. The air inlet pipe 4 passes through the shell cylinder 6. This avoids the accumulation of gas or liquid inside the housing and achieves better gas-liquid separation.

[0045] In one embodiment, a plurality of baffles 14 are provided between the top plate 12 and the bottom plate 15. The baffles 14 are wavy and arranged sequentially, with the gaps between them forming second flow channels, all of which are connected to the first flow channels. It should be noted that after gas-liquid separation in the structural cavity, the gas pushes the guide vane 13 under the action of pressure difference. The gas achieves a high flow velocity at the first flow channel and is ejected, acting vertically on the baffles 14 to reduce its speed and separate small droplets from the gas. These small droplets further form larger droplets that settle to the bottom of the shell. This further optimizes the gas-liquid separation effect, allowing the gas and liquid to contact and separate more fully during the flow process.

[0046] In one embodiment, a demister 3 is further included. The demister 3 is horizontally disposed within the housing, dividing the accommodating cavity into a first cavity and a second cavity. The air inlet, the first flow channel, and the liquid outlet 8 of the demister 3 are all connected to the first cavity, and the air outlet and the air outlet 1 of the demister 3 are both connected to the second cavity. It should be noted that the gas, after gas-liquid separation by the structural cavity and the baffle plate 14, rises inside the housing to the demister 3. The demister 3 intercepts and captures small droplets, which then condense into larger droplets that fall to the bottom of the housing under gravity. The demister 3 can be any structure capable of separating fine liquids; in this embodiment, preferably, the demister 3 is a wire mesh demister 3. Thus, after multiple gas-liquid separations based on different separation principles, the gas is sent out through the air outlet 1, further removing tiny droplets and improving the purity of the gas.

[0047] The second aspect of this utility model provides a method for operating a gas-liquid separator suitable for a wide range of fluctuating operating conditions, which will be described in detail below.

[0048] A method for operating a gas-liquid separator suitable for a wide range of fluctuating operating conditions, based on the gas-liquid separator suitable for a wide range of fluctuating operating conditions provided in any of the above embodiments, includes:

[0049] In the initial state, the air inlet pipe 4 is opened, and the gas-liquid mixture is introduced into the structural cavity. The gas-liquid mixture undergoes gas-liquid separation in the structural cavity and pushes the guide vane 13 to rotate outward. The first flow channel between the guide vanes 13 is opened, and the gas and liquid obtained by gas-liquid separation are introduced into the receiving cavity through multiple first flow channels. The gas is discharged from the air outlet 1, and the liquid is discharged from the liquid outlet 8.

[0050] When the flow rate of the gas-liquid mixture increases, the gas-liquid mixture pushes the guide vane 13 to rotate outward, and the first flow channel enlarges;

[0051] When the flow rate of the gas-liquid mixture decreases, the rotary assembly pulls the guide vane 13 to rotate inward, and the first flow channel decreases.

[0052] Therefore, this utility model provides a gas-liquid separator suitable for a wide range of fluctuating operating conditions, solving the technical problems of low separation efficiency, high energy consumption, and complex maintenance in existing gas-liquid separators, and achieving beneficial effects: The working method achieves adaptive adjustment of the gas-liquid mixture flow rate through the synergistic action of the guide vane 13 and the rotating assembly. When the flow rate increases, the guide vane 13 rotates outward, increasing the first flow channel to accommodate the larger flow rate; when the flow rate decreases, the rotating assembly pulls the guide vane 13 inward, decreasing the first flow channel, thereby maintaining separation efficiency. This adaptive capability enables the gas-liquid separator to operate stably under a wide range of fluctuating operating conditions. In the initial state, the gas... The liquid mixture is introduced into the structural cavity for gas-liquid separation. Because the size of the structural cavity is larger than that of the inlet pipe 4, the velocity of the gas-liquid mixture decreases within the larger structural cavity, and the droplets fall under the influence of gravity, thereby improving the separation efficiency. The separated gas and liquid enter the receiving cavity through the first flow channel and are discharged from the outlet 1 and the drain port 8, respectively. Since this working method can adapt to changes in flow rate, it avoids equipment overload or damage caused by flow fluctuations, improves equipment reliability and service life, and reduces maintenance costs. This working method is simple and easy to operate and maintain. At the same time, the design of the separator is also easy to disassemble and clean, reducing maintenance difficulty and costs.

[0053] like Figure 1-2 As shown, an optional working process of the gas-liquid separator of this utility model, suitable for a wide range of fluctuating operating conditions, is as follows:

[0054] Initially, the air inlet pipe 4 is opened, allowing the gas-liquid mixture to enter the structural cavity. Within the cavity, the gas-liquid mixture undergoes preliminary gas-liquid separation, pushing the guide vanes 13 outwards around the rotation axis 9. The spring is stretched, opening the first flow channels between the guide vanes 13. The initially separated gas-liquid mixture and liquid flow into multiple first flow channels. The initially separated liquid flows through the first flow channels into the second flow channels. The initially separated gas-liquid mixture is accelerated within the first flow channels and flows into the second flow channels. The initially separated gas-liquid mixture impacts the baffle plate 14, causing preliminary gas-liquid separation. The gas-liquid mixture from gas-liquid separation undergoes secondary gas-liquid separation in the second channel. The liquid from the initial gas-liquid separation, the gas-liquid mixture from the secondary gas-liquid separation, and the liquid from the secondary gas-liquid separation are introduced into the receiving cavity through the second flow channel. The liquid from the initial gas-liquid separation and the liquid from the secondary gas-liquid separation are deposited at the bottom of the shell. The gas-liquid mixture from the secondary gas-liquid separation enters the demister 3 through the receiving cavity and undergoes further gas-liquid separation. The liquid from the secondary separation falls into the bottom of the shell through the demister 3. The gas from the secondary separation enters the cavity through the demister 3 and is discharged through the outlet 1. The liquid at the bottom of the shell is discharged from the drain port 8.

[0055] When the flow rate of the gas-liquid mixture increases, the gas-liquid mixture pushes the guide vane 13 to rotate outward, and the first flow channel enlarges;

[0056] When the flow rate of the gas-liquid mixture decreases, the spring resets and pulls the rotating shaft 9 to rotate, which in turn pulls the guide vane 13 to rotate inward, thus reducing the flow channel size.
