Description

Technical Field

[0001] This application relates to the field of fluid processing technology, and in particular to fluid processing apparatus, control methods and electronic equipment. Background Technology

[0002] Existing fluid handling devices typically employ fixed unidirectional flow channels, where fluid can only flow in from a preset inlet and out from a preset outlet, and cannot flow in the opposite direction.

[0003] However, in applications such as backwashing, alternating flushing of pipelines, and preventing material deposition within the device, fluids need to flow in opposite directions. To achieve reverse flow, existing solutions involve adding additional reverse pipelines and switching valves, resulting in a complex device structure. Summary of the Invention

[0004] This application provides a fluid processing device, control method, and electronic device to solve the problem of complex bidirectional fluid circulation structures in related technologies.

[0005] To address the aforementioned technical problems, this application provides a fluid processing apparatus, which includes a tank and a pipe assembly.

[0006] The tank has a receiving cavity; the pipe assembly has at least a first opening and a second opening, the first opening and the second opening are respectively connected to the receiving cavity, the first opening and the second opening have a height difference along a first direction, and the setting height of the first opening is higher than the setting height of the second opening.

[0007] The tube assembly is used to guide fluid into the receiving cavity from the first opening and discharge the liquid after gas-liquid separation in the receiving cavity from the second opening; or, to guide fluid into the receiving cavity from the second opening and accumulate in the receiving cavity, and discharge it from the first opening after reaching a preset liquid level.

[0008] Optionally, the tube assembly includes a first tube and a second tube.

[0009] The first end of the first tube is located inside the receiving cavity, the second end of the first tube is located outside the receiving cavity, and the first end of the first tube is provided with a first opening, the opening direction of the first opening intersects with or is parallel to the first direction. The first end of the second tube is connected to the end face of the tank to communicate with the accommodating cavity. The second end of the second tube is located outside the accommodating cavity. The first end of the second tube is provided with a second opening. The opening direction of the second opening is parallel to or intersects with the first direction.

[0010] Optionally, at least one through hole is provided on the first end wall of the first tube; The tube assembly also includes at least one third tube, which is disposed in the accommodating cavity. The first end of the third tube is connected to a through hole, and the second end of the third tube is provided with a third opening. The opening direction of the third opening intersects with the first direction. The third tube is used to guide the fluid in the first tube to flow out from the third opening and then rotate around the circumference of the tank to achieve gas-liquid separation.

[0011] Optionally, the opening direction of the third opening is tangent to the side wall of the tank.

[0012] Optionally, the opening direction of the third opening is perpendicular to the first direction.

[0013] Optionally, the tube assembly includes two third tubes, the third openings of which are symmetrically arranged about the central axis of the tank.

[0014] Optionally, the opening directions of the third openings of the two third tubes are opposite.

[0015] Optionally, the third opening has a height difference with the first opening in the first direction.

[0016] To address the aforementioned technical problems, this application also provides a control method applied to the aforementioned fluid processing device, which has a first operating mode and a second operating mode. The control method includes: In the first working mode, the control fluid flows through the pipe assembly and enters the receiving cavity from the first opening of the pipe assembly. The liquid that has undergone gas-liquid separation in the receiving cavity is discharged from the second opening. In the second working mode, the control fluid flows through the pipe assembly, enters the receiving cavity from the second opening of the pipe assembly, accumulates in the receiving cavity, and is discharged from the first opening after reaching the preset liquid level.

[0017] To address the aforementioned technical problems, this application also provides an electronic device that includes the aforementioned fluid processing apparatus.

[0018] Unlike existing technologies, the advantages of this application are as follows: The pipe assembly of this application has a first opening and a second opening with a height difference. Fluid can flow in from the first opening and out from the second opening, or vice versa, achieving bidirectional circulation without the need for additional pipelines or switching valves. The device is simple and miniaturized. Furthermore, since the first opening is higher than the second opening, when the fluid is a gas-liquid two-phase fluid or a gas-liquid-solid three-phase fluid, gas-liquid separation can occur when the fluid flows out from the first opening due to the height difference (i.e., gravity). This causes the gaseous fluid to rise and the liquid or solid-liquid fluid to sink. The substance flowing out from the second opening is either liquid or solid-liquid fluid within the fluid. In this case, the pipe assembly can not only transport the fluid but also act as a separator to separate the fluid. When the fluid flows in from the second opening, separation usually does not occur. In this case, the pipe assembly only serves a transport function, and the tank acts as a storage container to store the fluid. This application can control the inflow and outflow openings of the fluid according to the actual required fluid state to adapt to different working conditions. Attached Figure Description

[0024] According to some embodiments of this application, please refer to Figures 1-4 This application provides a fluid processing device 10, which can process fluids including but not limited to transportation and storage. Fluid refers to a flowable substance, including liquid fluids, gaseous fluids, gas-liquid two-phase fluids, solid-liquid two-phase fluids, and gas-liquid-solid three-phase fluids. Liquid fluids can be water, oil, condensate, refrigerant, or others; gaseous fluids can be air, water vapor, or others; gas-liquid two-phase fluids can be mixtures of air and water, air and oil, steam and condensate, or others; solid-liquid mixtures can be slurry, ink, paste, or others; and gas-liquid-solid three-phase fluids can be oil-gas-sand three-phase flow, air flotation mixtures, or others. The specific type can be determined according to the application field, application scenario, and operating conditions of the fluid processing device 10.

[0025] In some embodiments, the fluid handling device 10 includes a tank 20 and a pipe assembly 21. The tank 20 and the pipe assembly 21 are either integrally formed or detachably connected. For the integrally formed connection, the tank 20 and pipe assembly 21 are integrally formed to ensure a stable and tight connection, preventing fluid leakage from the connection point. For the detachable connection, the tank 20 or pipe assembly 21 can be replaced when damaged, worn, or when the application scenario or operating conditions change. Furthermore, when cleaning the fluid handling device 10 is required, the detachable connection allows for disassembly followed by cleaning, improving cleanliness and reducing stain residue and fluid deposition. In some embodiments, the detachable connection method between the tank 20 and pipe assembly 21 includes, but is not limited to, a flange connection, a threaded connection, a clamp connection, a ferrule connection, and a connector connection.

[0026] The tank 20 of this application is a device capable of performing functions such as storage, mixing, and separation. The tank 20 includes, but is not limited to, a storage tank, mixing tank, reaction tank, and separation tank. The tank 20 has a accommodating cavity 22, which refers to the hollow area inside the tank 20 surrounded by walls (i.e., bottom wall, top wall, and side walls) and used for holding, storing, or processing fluids. When the fluid processing device 10 is in operation, the accommodating cavity 22 can be in one of the following states: fully filled with liquid or pure liquid phase (e.g., a liquid storage tank), partially filled with liquid (e.g., a top-inlet, bottom-outlet reaction tank), gas-liquid coexistence, or pure gas phase (e.g., a gas storage tank). In one application scenario, the shape and size of the accommodating cavity 22 can be determined according to actual conditions. For example, the cross-section of the accommodating cavity 22 can be square, circular, near-circular, trapezoidal, or other shapes; no limitation is made here. In one application scenario, to achieve the largest possible volume utilization rate, the tank 20 is typically cylindrical, i.e., the bottom of the tank 20 is flat or conical. In one application scenario, to prevent fluid from remaining or depositing inside the tank 20, the inner wall of the tank 20 must be smooth and without wrinkles.

[0027] The pipe assembly 21 of this application has a conduit supporting fluid flow or passage, and the pipe assembly 21 includes, but is not limited to, at least one conduit. In some embodiments, the pipe assembly 21 has at least a first opening 23 and a second opening 24. The shape and size of the first opening 23 and the second opening 24 can be determined according to actual conditions. For example, the cross-sections of the first opening 23 and the second opening 24 are both circular or near-circular. The first opening 23 and the second opening 24 are respectively connected to the receiving cavity 22. There is a height difference between the first opening 23 and the second opening 24 along a first direction X1, and the setting height of the first opening 23 is higher than the setting height of the second opening 24.

[0028] In some embodiments, the first direction X1 refers to the extension direction of the tank 20. When the tank 20 is a columnar or cylindrical structure, the extension direction of the tank 20 is parallel to the central axis direction of the tank 20. In some embodiments, in the installation or use state of the tank 20, the tank 20 extends along the vertical direction (or the direction of gravity), and at this time the first direction X1 is parallel to the vertical direction (or the direction of gravity).

[0029] Since the first opening 23 and the second opening 24 are respectively connected to the receiving cavity 22, the pipe assembly 21 has two pipes, and the tank 20 has a first connecting hole and a second connecting hole corresponding to these two pipes. The first connecting hole and the second connecting hole are respectively adapted to the corresponding pipes, so that the pipe assembly 21 is connected to the receiving cavity 22. When the tank 20 and the pipe assembly 21 are detachably connected, the connection method between the pipe and the tank 20 includes, but is not limited to, threaded connection, flange connection, and compression fitting connection. It can be understood that the first connecting hole and the second connecting hole penetrate the wall of the tank 20.

[0030] In some embodiments, the installation height of the first opening 23 is ensured to be higher than the installation height of the second opening 24 by adjusting the installation positions of the first connecting hole and the second connecting hole on the tank body 20. For example, both the first connecting hole and the second connecting hole are located on the bottom wall of the tank body 20; or, both the first connecting hole and the second connecting hole are located on the side wall of the tank body 20; or, one of the first connecting hole and the second connecting hole is located on the bottom wall of the tank body 20, and the other of the first connecting hole and the second connecting hole is located on the side wall of the tank body 20.

[0031] In some embodiments, the length of the pipe in the pipe assembly 21 is adjusted to ensure that the height of the first opening 23 is higher than the height of the second opening 24. For example, both the first and second connecting holes are located on the bottom wall of the tank 20. When the first end of the pipe corresponding to the first connecting hole and the first end of the pipe corresponding to the second connecting hole are at the same horizontal plane, the length of the pipe corresponding to the first connecting hole is greater than the length of the pipe corresponding to the second connecting hole, so that the second ends of the pipe corresponding to the first connecting hole and the second end of the pipe corresponding to the second connecting hole are at different horizontal planes. In other words, the first ends of the two pipes are at the same horizontal plane, while the second ends of the two pipes are at different horizontal planes.

[0032] The pipe assembly 21 of this application is used to transport fluid from other equipment to the receiving cavity 22 of the tank 20, or to transport the fluid stored in the receiving cavity 22 to other equipment, or to change the flow direction of the fluid to achieve guidance, or to divide a single fluid into multiple fluids to achieve diversion, or to merge multiple fluids into a single fluid to achieve convergence, or other purposes.

[0033] In some embodiments, the tube assembly 21 is used to guide fluid from the first opening 23 into the receiving cavity 22 and discharge the liquid after gas-liquid separation in the receiving cavity 22 from the second opening 24; or, to guide fluid from the second opening 24 into the receiving cavity 22, where it accumulates and discharges from the first opening 23 after reaching a preset liquid level, the preset liquid level being determined based on the height of the first opening 23 and the receiving cavity 22. It can be understood that when the fluid is a gas-liquid two-phase fluid or a gas-liquid-solid three-phase fluid, it must flow in from the first opening 23 for the tube assembly 21 to function as a separator and perform its separation function.

[0034] Taking gas-liquid separation as an example, gas-liquid separation is achieved under the action of gravity. Due to the density difference between gas and liquid, the liquid naturally settles under the action of gravity, while the gas rises. Alternatively, gas-liquid separation is achieved through centrifugal separation. The gas-liquid two-phase fluid is rotated at high speed, generating centrifugal force. The liquid in the gas-liquid two-phase fluid is thrown against the wall (such as the side wall) of the tank 20, and the gas rises naturally after being separated by the cyclone. Alternatively, gas-liquid separation is achieved through inertial collision. By changing the direction of airflow, the denser liquid cannot follow the direction of airflow due to inertia and is drawn off by impacting the wall of the tank 20, while the gas rises.

[0035] Taking the example that both the first connecting hole and the second connecting hole are located on the bottom wall of the tank 20, the second opening 24 and the corresponding second connecting hole are on the same horizontal plane, that is, the second opening 24 is parallel to the bottom wall of the tank 20. Since there is a height difference between the first opening 23 and the second opening 24 along the first direction X1, and the setting height of the first opening 23 is higher than the setting height of the second opening 24, at least part of the pipe corresponding to the first opening 23 is located in the accommodating cavity 22. That is, there is a height difference between the first opening 23 and the bottom wall of the tank 20. When the gas-liquid two-phase fluid flows out from the first opening 23, the gas-liquid two-phase fluid undergoes gas-liquid separation under the action of gravity. After gas-liquid separation, the liquid settles under the action of gravity, and the gas and liquid rise. At this time, the upper layer (or upper half) of the accommodating cavity 22 stores gaseous fluid, and the lower layer (or lower half) of the accommodating cavity 22 stores liquid fluid. In other application scenarios, the first connecting hole and the second connecting hole are both located on the side wall of the tank 20, and one of the first connecting hole and the second connecting hole is located on the bottom wall of the tank 20 and the other is located on the side wall of the tank 20, please refer to the above description.

[0036] In some embodiments, when there is a height difference between the second opening 24 and the bottom wall of the tank 20, the fluid flowing out of the second opening 24 can also be separated. This separation can be gas-liquid separation or other methods, as detailed above.

[0037] In some embodiments, when gas-liquid separation is achieved under gravity, the opening directions of the first opening 23 and the second opening 24 are parallel to or intersect with the first direction X1. In one application scenario, the opening directions of the first opening 23 / second opening 24 are upward; or, the opening directions of the first opening 23 / second opening 24 intersect with the vertical direction, and the angle of intersection is a right angle or an acute angle, that is, the openings of the first opening 23 / second opening 24 are inclined upward, inclined downward, or parallel to the vertical direction. Specifically, for the first opening 23, the second opening 24, and the third opening 25 (hereinafter referred to as the third opening), when the pipe body corresponding to the opening is a straight pipe, the opening is an axial opening, and the opening direction is parallel to the axis of the straight pipe, with fluid entering and exiting along the pipe body axis; when the pipe body corresponding to the opening is a curved pipe, the opening direction is the normal direction of the opening cross-section.

[0038] In this context, the axis of a straight pipe is a virtual straight line connecting the geometric centers of its cross-section; the axis of a curved pipe is a virtual curve swept along the bending path by the center of its cross-section. It is not a straight line, but an arc with curvature (e.g., the axis of a 90° bend is a quarter-circle arc). The tangent direction at each point on the axis is the instantaneous flow direction of the fluid at that point.

[0039] In some embodiments, when gas-liquid separation is achieved by centrifugal separation or inertial collision, the opening directions of the first opening 23 and the second opening 24 intersect with the first direction X1, and the angle between the intersections is a right angle or an acute angle. When the angle is a right angle, the gas-liquid separation effect is optimal.

[0040] It is understandable that when the fluid flowing out of the first opening 23 is a liquid or gaseous fluid, the fluid flowing out of the first opening 23 will not separate, and the same applies to the second opening 24. In practical applications, the flow direction of the fluid into the receiving cavity 22 is determined based on the state of the fluid. Specifically, when the inflowing fluid is a gas-liquid two-phase fluid or a gas-liquid-solid three-phase fluid, and the second opening 24 is at the same level as the bottom wall of the tank 20, if it is necessary for the pipe assembly 21 to discharge liquid or a solid-liquid mixture, the first opening 23 is used as the inlet and the second opening 24 is used as the outlet. When the inflowing fluid is a gas-liquid two-phase fluid or a gas-liquid three-phase fluid, and there is a height difference between the second opening 24 and the bottom wall of the tank 20, if it is necessary for the pipe assembly 21 to discharge liquid or a solid-liquid mixture, the first opening 23 is used as the inlet and the second opening 24 is used as the outlet, or the second opening 24 is used as the inlet and the first opening 23 is used as the outlet. When the inflowing fluid is a liquid or a gaseous fluid, the first opening 23 can be used as the inlet and the second opening 24 as the outlet, or the second opening 24 can be used as the inlet and the first opening 23 as the outlet.

[0041] According to some embodiments of this application, the pipe assembly 21 includes a first pipe 25 and a second pipe 26, both of which have conduits. The first pipe 25 and the second pipe 26 may have the same or different shapes and dimensions; the conduits corresponding to the first pipe 25 and the conduits corresponding to the second pipe 26 may be the same or different.

[0042] In some embodiments, a first end of the first tube 25 is disposed within the accommodating cavity 22, and a second end of the first tube 25 is disposed outside the accommodating cavity 22. The first end of the first tube 25 has a first opening 23, the opening direction of which intersects with or is parallel to a first direction X1. When the opening direction is parallel to the first direction X1 and the first direction X1 is parallel to the vertical direction, the opening direction is parallel to the vertical direction, and the first opening 23 extends vertically. When the opening direction intersects with the first direction X1, the first opening 23 extends in a direction inclined relative to the vertical direction. In one application scenario, the first tube 25 is a straight tube, and the first opening 23 is located on the end face of the first tube 25. In this case, the opening direction of the first opening 23 is the same as the extension direction of the first tube 25. The gas-liquid two-phase fluid or gas-liquid-solid three-phase fluid flowing out from the first opening 23 of the first tube 25 can be separated under gravity to extract gas. In one application scenario, the first tube 25 is a curved tube, and the first opening 23 is located on the end face of the first tube 25. At this time, the first tube 25 has two extending directions, and the included angle between the two extending directions is an acute angle, an obtuse angle, and a right angle. The opening direction of the first opening 23 is the same as one of the extending directions. The gas-liquid two-phase fluid or gas-liquid-solid three-phase fluid flowing out from the first opening 23 of the first tube 25 can be separated by centrifugal force or inertia to extract gas.

[0043] In one application scenario, the first tube 25 passes through the first connecting hole, so that the two ends of the first tube 25 are respectively located inside and outside the receiving cavity 22. At this time, the two ends of the first tank 20 are respectively spaced apart from the wall surface of the tank 20. Specifically, the first end of the first tube 25 is spaced apart from the inner wall surface of the tank 20 (such as the top wall opposite to the bottom wall), and the second end of the first tube 25 is spaced apart from the outer wall surface of the tank 20 (such as the bottom wall).

[0044] In some embodiments, the first end of the second tube 26 is connected to the wall (e.g., bottom wall) of the tank 20 to communicate with the receiving cavity 22. The second end of the second tube 26 is located outside the receiving cavity 22. The first end of the second tube 26 has a second opening 24, the opening direction of which is parallel to or intersects with the first direction X1. When the opening direction is parallel to the first direction X1 and the first direction X1 is parallel to the vertical direction, the opening direction is parallel to the vertical direction, and the second opening 24 extends vertically. When the opening direction intersects with the first direction X1, the second opening 24 extends in a direction inclined relative to the vertical direction. In one application scenario, the second tube 26 is a straight tube, and the opening direction of the second opening 24 is the same as the extension direction of the second tube 26. In another application scenario, the second tube 26 is a curved tube, and the second tube 26 has two extension directions, the included angle of which is an acute angle, an obtuse angle, and a right angle, and the opening direction of the second opening 24 is the same as one of the extension directions.

[0045] In one application scenario, the first end of the second tube 26 is located inside the second connecting hole to communicate with the receiving cavity 22, and the second end of the second tube 26 is located outside the receiving cavity 22. In this case, the first end of the second tube 26 is parallel to the inner wall surface (e.g., the bottom wall) of the tank 20, and the second end of the second tube 26 is spaced apart from the outer wall surface (e.g., the bottom wall) of the tank 20. In another application scenario, the second end of the second tube 26 and the second end of the first tube 25 are on the same horizontal plane, and this horizontal plane is perpendicular to the first direction X1.

[0046] It is understandable that since the opening direction of the first opening 23 is parallel to or intersects with the first direction X1, and the opening direction of the second opening 24 is parallel to or intersects with the first direction X1, the second tube 26 is parallel to or intersects with the first tube 25. The intersection here does not refer to direct physical interference, but rather the intersection of the extension directions of the two tubes.

[0047] In some embodiments, both the first tube 25 and the second tube 26 are straight tubes, with the length of the first tube 25 being greater than the length of the second tube 26, i.e., the first tube 25 is a long tube and the second tube 26 is a short tube. In one application scenario, the first tube 25 is a curved tube, having a first part and a second part. The first part passes through the tank 20, with one end of the first part located outside the receiving cavity 22 and the other end located inside the receiving cavity 22 and connected to the second part. The second part is located inside the receiving cavity 22, and the connection between the first part and the second part is bent. The second tube 26 is a straight tube, with the length of the first part of the first tube 25 being greater than the length of the second tube 26, and the length of the second part of the first tube 25 being less than the length of the second tube 26. The length of the first part of the first tube 25 is greater than the length of the second part.

[0048] According to some embodiments of this application, at least one through hole is provided on the wall of the first end of the first pipe body 25. The shape of the through hole includes, but is not limited to, a circular hole, an elliptical hole, and a rectangular hole, to adapt to different fluid flow rates or injection angle requirements. It is understood that the through hole penetrates the wall of the first pipe body 25. When multiple through holes are present, they are evenly distributed along the circumference of the first pipe body 25, or arranged spirally along the axial direction of the first pipe body 25, or concentrated on one side of the pipe wall. For example, when four through holes are provided, they can be arranged on the same circumference at 90° intervals; when six through holes are provided, they can be staggered into two rows of three.

[0049] In one application scenario, the first pipe body 25 is a straight pipe, and the axial direction of the through hole is perpendicular or parallel to the radial direction of the first pipe body 25. When parallel, the through hole is located on the side wall of the first pipe body 25, allowing the fluid to flow radially outward when flowing out of the through hole. When perpendicular, the through hole is located on the end wall of the first pipe body 25, allowing the fluid to flow axially outward when flowing out of the through hole. In another application scenario, the first pipe body 25 is a curved pipe (such as an L-shaped pipe), and the through hole is located in the second part of the first pipe body 25, with the axial direction of the through hole perpendicular or parallel to the radial direction of the second part. It can be understood that, in order to ensure that the first opening 23 can normally discharge fluid and to reduce the impact on the fluid flow, the first opening 23 is spaced apart from the inner wall surface (such as the top wall or side wall) of the tank 20, and the first end of the first pipe body 25 is spaced apart from the inner wall surface (such as the top wall or side wall) of the tank 20.

[0050] In some embodiments, the tube assembly 21 further includes at least one third tube 27 disposed within the receiving cavity 22. The first end of the third tube 27 communicates with a through hole, and the second end of the third tube 27 has a third opening 28. The opening direction of the third opening 28 intersects with the first direction X1. The third tube 27 guides the fluid in the first tube 25 to flow out through the third opening 28 and rotate circumferentially along the tank 20, thereby achieving gas-liquid separation. The second end of the third tube 27 is spaced apart from the inner wall surface (such as the top wall or side wall) of the tank 20, and the third opening 28 is also spaced apart from the inner wall surface (such as the top wall or side wall) of the tank 20 to ensure that the fluid can flow out normally through the third opening 28 and to reduce the impact on the fluid flow.

[0051] It is understood that the number of third tubes 27 is less than or equal to the number of through holes. The third opening 28 and the first opening 23 have a height difference in the first direction X1 to prevent the fluids flowing from these two openings from affecting each other. Specifically, the opening direction of the third opening 28 intersects the first direction X1, and the angle between the intersections is a right angle, an acute angle, or an obtuse angle.

[0052] In one application scenario, the third tube 27 is a straight tube with a through hole located on the side wall of the first tube 25. The axis of the through hole is parallel to the axis of the third tube 27. The axis of the third opening 28 is also parallel to the axis of the third tube 27. The axis or extension direction of the third tube 27 intersects the first direction X1. In another application scenario, the third tube 27 is a curved tube (such as an L-shaped tube). The through hole is located on the end wall of the first tube 25. The axis of the through hole is parallel to a portion of the axis of the third tube 27 and intersects with another portion of the axis of the third tube 27. The axis of the third opening 28 is parallel to a portion of the axis of the third tube 27 and intersects with another portion of the axis of the third tube 27.

[0053] In some embodiments, the third opening 28 is a tangential opening, extending tangentially to the sidewall of the tank 20. This ensures the opening direction of the third opening 28 is tangential to the sidewall of the tank 20. Fluid entering the receiving cavity 22 through the third opening 28 rotates at high speed tangentially to the inner wall of the tank 20, generating centrifugal force. This centrifugal force can throw denser liquids or solid-liquid mixtures towards the tank wall, while less dense gases gather towards the center for extraction. Furthermore, tangential feeding avoids direct impact of the fluid on the liquid surface inside the tank, reducing splashing and foam generation. It also helps prevent the settled bottom sediment from being disturbed by the feed flow, improving sedimentation and separation efficiency. Additionally, tangential feeding of the third opening 28 to the sidewall of the tank 20 eliminates the need for additional components such as guide vanes or cyclones inside the tank 20 to achieve good separation, simplifying the internal structure of the tank 20 and reducing manufacturing costs.

[0054] In some embodiments, the third opening 28 is a tangential inlet, and the angle between the axis of the corresponding third tube 27 and the tangential direction of the side wall of the tank 20 at the third opening 28 does not exceed 10 degrees, preferably 0 degrees, i.e., they are completely tangent. In this case, the opening direction of the third opening 28 is perpendicular to the first direction X1. When the fluid flows out of the third opening 28, almost all of the momentum of the flow is converted into tangential rotational momentum. Almost no radial component impacts the wall of the tank 20 (i.e., the tank wall) to cause energy loss, and no component pointing towards the axis disturbs the central flow field. All the kinetic energy is used to propel the fluid to rotate along the tank wall.

[0055] It is understandable that, under the same inlet flow rate, the centrifugal force generated by complete tangency is the greatest, the rotation speed is the fastest, and the separation efficiency is the highest.

[0056] In some embodiments, the third pipe body 27 is integrally formed with the first pipe body 25 or is detachably connected. The detachable connection method includes, but is not limited to, threaded connection, welding, flange connection, and connector connection. For the integrally formed connection, the integral forming of the third pipe body 27 and the first pipe body 25 ensures a stable and tight connection, preventing fluid leakage from the connection point. For the detachable connection, targeted replacement can be performed when the third pipe body 27 or the first pipe body 25 is damaged or worn, or when the application scenario or operating conditions change. Furthermore, when cleaning the fluid handling device 10 is required, the detachable connection allows for disassembly and separate cleaning, improving cleanliness and reducing fluid deposition or stain residue.

[0057] In some embodiments, the number of third tubes 27 is greater than or equal to 2. When there are multiple third tubes 27, the fluid flows from the first tube 25 to at least two third tubes 27 to achieve flow diversion, which can reduce the impact force of the fluid on the first tube 25 and thus reduce impact wear.

[0058] In some embodiments, the tube assembly 21 includes two third tubes 27, the third openings 28 of which are symmetrically arranged about the central axis of the tank 20. In the installed or used state, the central axis of the tank 20 is parallel to a first direction X1, which is parallel to the vertical direction. In one application scenario, the third tubes 27 are straight tubes, and when the third openings 28 of the two third tubes 27 are symmetrically arranged about the central axis of the tank 20, the angle between the axes of the two straight tubes is 180°. In another application scenario, the third tubes 27 are curved tubes (such as L-shaped tubes).

[0059] In some embodiments, the third openings 28 of the two third tubes 27 are located at the same horizontal height, and when the fluid flowing out of the third openings 28 of the two third tubes 27 enters the tank 20, the tangential direction of the openings is the same as that of the inner circumference of the tank 20. At this time, the axes of the third openings 28 of the two third tubes 27 are parallel to each other and point in the same direction, that is, the opening directions are the same. From a top-down view (i.e., from above), one third opening 28 is used to guide the fluid to rotate clockwise, and the other third opening 28 is used to guide the fluid to rotate counterclockwise. The two swirling flows from the two third openings 28 collide with each other in the receiving cavity 22, generating strong turbulence, which is suitable for application scenarios that require rapid mixing and do not want to generate vortices.

[0060] In some embodiments, the third openings 28 of the two third tubes 27 are located at the same horizontal height, and when the fluid flowing out of the third openings 28 of the two third tubes 27 enters the tank 20, the tangential directions of the openings and the inner circumference of the tank 20 are opposite. At this time, the axes of the third openings 28 of the two third tubes 27 are parallel to each other but point in opposite directions, that is, the opening directions are opposite. From a top view, the two openings guide the fluid to rotate in the same direction, either clockwise or counterclockwise. The two swirling flows out of the two third openings 28 superimpose to form a strong and uniform swirling field within the accommodating cavity 22, which is suitable for applications requiring strong centrifugal force. It can be understood that when the fluid is a two-phase or three-phase fluid containing gas, regardless of whether the opening directions of the third openings 28 of the two third tubes 27 are the same or opposite, the fluid flowing out of the third openings 28 can be separated (such as gas-liquid separation).

[0061] According to some embodiments of this application, this application also provides a control method applied to the fluid processing device 10 of any of the above embodiments. The fluid processing device 10 has a first operating mode and a second operating mode. The control method includes (not shown): S11: In the first working mode, the control fluid flows through the pipe assembly and enters the receiving cavity from the first opening of the pipe assembly. The liquid that has undergone gas-liquid separation in the receiving cavity is discharged from the second opening.

[0062] It is understood that when the fluid processing device 10 operates in the first working mode, the fluid enters at a high temperature and exits at a low temperature, and the pipe assembly 21 simultaneously serves to transport and separate the fluid. The tank 20 is used as a storage tank to store fluid. When the fluid flowing out from the first opening 23 is a gas-liquid two-phase fluid or a gas-liquid-solid three-phase fluid, the tank 20 is used to store the fluid after gas-liquid separation or the fluid after gas-liquid-solid separation. The fluid flowing out from the second opening 24 is a liquid fluid or a solid-liquid two-phase fluid.

[0063] S12: In the second working mode, the control fluid flows through the pipe assembly, enters the receiving cavity from the second opening of the pipe assembly, accumulates in the receiving cavity, and is discharged from the first opening after reaching the preset liquid level.

[0064] It is understood that when the fluid processing device 10 operates in the second working mode, the fluid enters from a lower position and exits from a higher position. The pipe assembly 21 serves to transport the fluid. In specific scenarios, the pipe assembly 21 can also separate the fluid. The tank 20 is used as a storage tank to store the fluid or to store the separated liquid fluid or solid-liquid two-phase fluid. When the fluid flowing out of the second opening 24 is a gaseous fluid, the fluid flowing out of the first opening 23 is also a gaseous fluid; when the fluid flowing out of the second opening 24 is a liquid fluid, the fluid flowing out of the first opening 23 is also a liquid fluid; when the fluid flowing out of the second opening 24 is a gas-liquid two-phase fluid, and the fluid flowing out of the second opening 24 is not separated, the fluid flowing out of the first opening 23 is also a gas-liquid two-phase fluid; when the fluid flowing out of the second opening 24 is a gas-liquid-solid three-phase fluid, and the fluid flowing out of the second opening 24 is not separated, the fluid flowing out of the first opening 23 is also a gas-liquid two-phase fluid, with solid deposition.

[0065] In some embodiments, the first operating mode corresponds to a gas-liquid separation mode, and the second operating mode corresponds to a storage mode. When gas-liquid separation is required, the fluid processing device 10 switches to the first operating mode; when storage is required, the fluid processing device 10 switches to the second operating mode.

[0066] In some embodiments, the first working mode and the second working mode are switched by the system control of the feed inlet (i.e., whether the fluid flows in from the first opening 23 or the second opening 24). Compared with the manual switching method, the system control is more convenient, can reduce errors, and can achieve rapid switching.

The electronic device 100 involved in this application includes, but is not limited to, a heat exchanger, a household water purifier, a refrigeration device (such as an air conditioner), a cleaning device (such as a cleaning machine), and a sewage treatment device.
