It is arranged between the top plate 12 and the bottom plate 15, and the guide vanes 13 are arranged at intervals to form a first flow channel that can be opened and closed. A structural cavity is formed between the top plate 12, the bottom plate 15 and the plurality of guide vanes 13, and the structural cavity is connected to the intake pipe 4 and the size of the structural cavity is larger than the size of the intake pipe 4; wherein, a gas-liquid mixture is introduced into the structural cavity through the intake pipe 4, and the gas-liquid mixture can be separated into gas and liquid in the structural cavity and push the guide vanes 13 to rotate outward, and the rotating assembly can drive the guide vanes 13 to rotate inward, and the gas and liquid obtained by gas-liquid separation are introduced into the accommodating cavity through the plurality of first flow channels, and the gas is discharged from the gas outlet 1, and the liquid is discharged from the liquid discharge port 8.

[0023] It should be noted that the gas-liquid mixture with a certain pressure flows into the structural cavity through the intake pipe 4.

A part of the liquid is separated by gravity and settles on the bottom plate 15. The settled liquid is discharged through the first flow channel driven by the airflow and accumulates at the bottom of the tank. The gas-liquid mixture that has been initially separated has an increased flow velocity and expanded volume in the first flow channel. According to the law of conservation of energy, the increase in kinetic energy brings about a decrease in internal energy, that is, a decrease in temperature, which helps the steam in the gas phase to condense and precipitate, and the steam-water separation is performed again. The rotating component is any structure that can rotate automatically, and can be driven by a motor or other driving device, or by a spring. In the present embodiment, preferably, a spring is provided on the rotating component. The number and outlet angle of the guide vanes 13 can be set as needed to meet the gas-liquid separation effect within a wide range of operating conditions.

[0024] In order to enable the gas-liquid mixture to push the guide vane 13 and achieve self-adaptation, in the present embodiment, the guide vane 13 is plate-shaped or drop-shaped, one side wall of the guide vane 13 is connected to the rotating assembly, and the other side wall of the guide vane 13 is arranged between the top plate 12 and the bottom plate 15 and rotates around the rotating assembly.

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 bottom plate 15 through an axle pin.

[0029] In order to better achieve gas-liquid separation and remove the separated gas and liquid, in this embodiment, the shell includes an upper head 2, a lower head 7 and a shell cylinder 6, the upper head 2 is provided with the gas outlet 1, the upper head 2 is sealed at the upper end of the shell cylinder 6, the lower head 7 is sealed at the lower end of the shell cylinder 6, the lower head 7 is provided with the drain port 8, and the shell cylinder 6 is penetrated by the air inlet pipe 4.

[0030] In order to further improve the separation efficiency, in the present embodiment, a plurality of baffles 14 are provided between the top plate 12 and the bottom plate 15. The baffles 14 are wavy in shape and are arranged in sequence. The arrangement gaps between the baffles 14 form second flow channels, and the second flow channels are connected to the first flow channels.

[0031] In order to further improve the separation efficiency, in this embodiment, a demister 3 is also included. The demister 3 is horizontally arranged in the shell so that the accommodating cavity is divided into a first cavity and a second cavity. The air inlet end, the first flow channel and the drain port 8 of the demister 3 are all connected to the first cavity, and the air outlet end and the air outlet 1 of the demister 3 are both connected to the second cavity. In one embodiment, the guide vane 13 is plate-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 arranged between the top plate 12 and the bottom plate 15 to rotate around the rotary assembly. Thus, the guide vane 13 can flexibly respond to the flow of the gas-liquid mixture and effectively adjust the size of the flow channel, thereby optimizing the gas-liquid separation effect, and at the same time, it is easy to clean and maintain, reducing the operating cost of the equipment.

[0032] In one embodiment, the rotary assembly includes a rotating shaft 9 and a spring. The rotating shaft 9 is rotatably arranged 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 is used to provide adjustment power for the guide vane 13. The type of the spring is not limited to a spiral spring, a volute spring, a leaf spring, etc. The guide vane 13 can rotate outward when pushed by the gas-liquid mixture, and the spring provides a rebound force, so that the guide vane 13 can rotate inward when the flow rate decreases. In this way, the stability and separation efficiency of the device are maintained.

[0033] In one embodiment, one end of the rotating shaft 9 is provided with a protrusion, the protrusion is provided on the side of the top plate 12 away from the bottom plate 15, the other end of the rotating shaft 9 is provided on the side of the bottom plate 15 away from the top plate 12, and the other end of the rotating shaft 9 is connected to one end of the spring. Thus, the installation and removal of the rotating shaft 9 are more convenient, and the stability of the rotating shaft 9 is also enhanced, thereby improving the overall performance of the device.

[0034] In one embodiment, the spring is a plane scroll spring 10, which is arranged on the side of the bottom plate 15 away from the top plate 12, and the plane scroll spring 10 is sleeved on the rotating shaft 9, the inner end of the plane scroll spring 10 is connected to the rotating shaft 9, and the outer end of the plane scroll spring 10 is hinged to the bottom plate 15 through an axle pin. It should be noted that the plane scroll spring 10 has the advantages of small size, large energy storage, and stable force value. In this way, while simplifying the device, it can provide a stable rebound force when the guide vane 13 is subjected to an external force, so that the guide vane 13 can rotate smoothly, thereby maintaining the stability of the flow channel and the separation efficiency.

[0035] In one embodiment, the top plate 12 is provided with a plurality of first connection holes arranged in an annular manner, the bottom plate 15 is provided with a plurality of second connection holes arranged in an annular manner, and the rotary assembly is inserted through the first connection holes and the second connection holes.

[0037] 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 the baffles 14 are arranged in sequence, and the arrangement gaps between the baffles 14 form a second flow channel, and the second flow channel is connected to the first flow channel. It should be noted that after the gas-liquid separation in the structural cavity, the gas pushes the guide vane 13 under the action of the pressure difference, and the gas is ejected at a higher flow rate in the first flow channel, and acts vertically on the baffles 14 to reduce the speed and separate the small droplets in the gas, and the small droplets further form large droplets and settle to the bottom of the shell; thereby, the gas-liquid separation effect is further optimized, so that the gas and liquid are more fully contacted and separated during the flow process. In one embodiment, it also includes a demister 3, which is horizontally arranged in the shell so that the accommodating cavity is divided into a first cavity and a second cavity. The air inlet end, the first flow channel and the liquid discharge port 8 of the demister 3 are all connected to the first cavity, and the air outlet end and the air outlet 1 of the demister 3 are all connected to the second cavity. It should be noted that the gas after gas-liquid separation through the structural cavity and the baffle 14 rises to the demister 3 inside the shell, and the demister 3 intercepts and captures small droplets, and then condenses into larger droplets, which fall to the bottom of the shell under the action of gravity; the demister 3 is any structure that can separate fine liquids. In this embodiment, preferably, the demister 3 adopts a wire mesh demister 3. Therefore, after different separation principles and multiple gas-liquid separations, the gas is sent out through the outlet 1, and the tiny droplets in the gas are further removed to improve the purity of the gas.

[0038] The second aspect of the present invention provides a working method of a gas-liquid separator suitable for a wide range of fluctuating working conditions, which is described in detail below.

The gas-liquid mixture of gas-liquid separation is subjected to secondary gas-liquid separation in the second channel, the liquid of the initial gas-liquid separation, the gas-liquid mixture of the secondary gas-liquid separation and the liquid of the secondary gas-liquid separation are passed into the containing cavity through the second flow channel, the liquid of the initial gas-liquid separation and the liquid of the secondary gas-liquid separation are deposited at the bottom of the shell, the gas-liquid mixture of the secondary gas-liquid separation enters the demister 3 through the containing cavity and is subjected to gas-liquid separation again, the liquid separated again falls into the bottom of the shell through the demister 3, the gas separated again enters the cavity through the demister 3 and is discharged from the gas outlet 1, and the liquid at the bottom of the shell is discharged from the liquid discharge port 8; 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 increases; When the flow rate of the gas-liquid mixture decreases, the spring reset pulls the rotating shaft 9 to rotate and then pulls the guide vane 13 to rotate inward, and the first flow channel decreases.
