Description

[0002] Cyclone separators can be used to control the humidity of the airflow at the outlet of the heat exchanger. Usually, the cyclone separator is composed of a stator impeller, a swirl chamber, a water separation chamber, a water baffle and other structures. The wet air flows in from the inlet of the stator impeller, generates a strong swirl under the action of the stator impeller and enters the swirl chamber. The liquid (water) in the air is thrown to the wall of the swirl chamber under the action of centrifugal force to form a liquid film, and flows into the water separation chamber with the airflow, and the liquid is discharged through the drainage hole in the water separation chamber.

[0003] The water separation efficiency of the cyclone separator is closely related to the strength of the swirl generated by the air flowing through the stator impeller. The swirl intensity can be increased by reducing the geometric angle of the stator blade outlet, but it will also increase the flow resistance. When the inlet air humidity is low, the water separation efficiency requirement is low, and when the air humidity is high, the water separation efficiency requirement is high.

[0010] In some embodiments, the hub has a central spiral channel running through both ends thereof, and the spiral direction of the central spiral channel is consistent with the swirl direction of the swirl blades.

[0014] In some embodiments, the air flow outlet of the water collection and drainage pipe is also connected to an air guide pipe, and a water retaining ring is provided in the air flow inlet of the air guide pipe.

[0015] The present invention also provides a control method for the above-mentioned cyclone separator, comprising the following steps:

[0016] Obtaining the airflow humidity at the airflow inlet of the inlet pipe and determining a change trend of the airflow humidity;

[0017] When the change trend of the airflow humidity is increasing, the rotating tail blade is controlled to rotate toward the side close to the windward surface of the swirl blade to reduce the blade outlet geometric angle; or,

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. 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.

They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0046] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below".

[0047] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0048] See also Figure 1 and Fig.12 As shown, according to an embodiment of the present invention, a cyclone separator is provided, which is specifically applied to the air outlet side of a heat exchanger to dehumidify the air flow after heat exchange with the heat exchanger, and includes an inlet pipe 1, and a stator impeller 2 is provided at the air flow inlet of the inlet pipe 1. The stator impeller 2 includes a hub 21 and a plurality of swirl blades 22 connected to the outer peripheral wall of the hub 21 and extending radially outward from the hub 21. When the air flow passes through each of the swirl blades 22, it will be guided to flow in a swirl state. Each of the swirl blades 22 has an inlet side close to the air flow inlet and an outlet side away from the air flow inlet. Flow side, and it can be understood that each swirl blade 22 has a windward side and a leeward side, and the swirl blade 22 also includes a rotating tail blade 23 on the side of each outflow side away from the inlet side, and each of the rotating tail blades 23 can be controlled to rotate by a preset angle to change the blade outlet geometric angle of the swirl blade 22. It can be understood that there can be a direct connection relationship between the aforementioned rotating tail blades 23 and the swirl blades 22, or a relationship of independent components arranged adjacent to each other, but no matter what kind of relationship it is, it should be ensured that the gap between the two positions where they are close should be as small as possible, and the two respectively have wind guide surfaces to maintain smooth docking.

[0049] In this technical solution, a rotating tail blade 23 that can form a docking relationship with the swirl blade 22 is provided on the outflow side of the swirl blade 22, and each rotating tail blade 23 can be driven to rotate a preset angle to thereby change the blade outlet geometric angle of each swirl blade 22. For example, when the humidity of the air flow increases, the rotating tail blades 23 are controlled to rotate to reduce the blade outlet geometric angle so as to increase the air flow resistance and thereby ensure the dehumidification effect; and when the humidity of the air flow decreases, the rotating tail blades 23 are controlled to rotate to increase the blade outlet geometric angle, which can reduce the resistance to the air flow, ensure the air flow rate and reduce the air flow loss. In this way, by controlling the rotation direction of the rotating tail blades 23 to change the blade outlet geometric angle according to different air flow dehumidification requirements, the dehumidification and water separation efficiency and flow resistance are taken into consideration.

[0050] The aforementioned stator impeller 2 can exist independently of the inlet pipe 1, that is, the stator impeller 2 can be assembled in the inlet pipe 1, and as a preferred embodiment, each of the swirl blades 22 is connected between the hub 21 and the inner wall of the inlet pipe 1, that is, at this time, each of the swirl blades 22 and the inlet pipe 1 is a whole, which can reduce the number of parts and simplify the assembly process. In this way, the inlet pipe 1 and the stator impeller 2 can be integrally formed by injection molding, which is very simple and convenient to manufacture.

[0051] In a specific embodiment, the rotating tail blade 23 has an assembly hole 231, and a rotating shaft 24 is inserted into the assembly hole 231. The inner end of the rotating shaft 24 is rotatably connected to the outer circumferential wall of the hub 21, and the outer end of the rotating shaft 24 is rotatably connected to the pipe wall of the inlet pipe 1, and extends out of the pipe wall of the inlet pipe 1, and also includes a driving component (not shown in the figure, not labeled), the driving component is outside the pipe wall, and the driving component can drive each of the rotating shafts 24 to rotate and thereby drive The rotating tail blade 23 rotates the preset angle. For example, a first groove (or through hole) is provided on the outer peripheral wall of the hub 21 at a position corresponding to each swirl blade 22, and a first through hole is provided on the pipe wall of the inlet pipe 1 at a position corresponding to each swirl blade 22. The cross-sections of both ends of the rotating shaft 24 are circular, so that a rotating connection is formed between the rotating shaft 24 and the inlet pipe 1 and the hub 21. In order to facilitate the assembly of the rotating shaft 24, the aperture of the first through hole should not be less than the radial maximum dimension of the rotating shaft 24.

[0052] In this technical solution, the rotation of the rotating shaft 24 is driven by the driving component, which in turn drives the rotation of the rotating tail blade 23. The driving component is located on the outer end of the driving shaft 24 outside the pipe wall of the inlet pipe 1, which can reduce the obstruction to the airflow in the inlet pipe 1 and can reduce the requirements for the waterproof performance of the driving component.

[0053] In a specific embodiment, the cross-section of the position where the rotating shaft 24 cooperates with the assembling hole 231 is rectangular, for example, a square, which can ensure the rotation synchronization of the rotating tail blade 23 while achieving the connection.

[0054] In some embodiments, a group of driving components, such as a rotary motor, can be respectively provided for the outer end of each rotating shaft 24 to be able to control the rotation angle of each rotating shaft 24, but this method is relatively complex in structural design, and has high requirements on the rotation synchronization of each motor, and the manufacturing cost is relatively high. Therefore, as a preferred implementation method, the driving component includes a driven gear 241 connected to the portion of each rotating shaft 24 extending outside the pipe wall of the inlet pipe 1, a ring gear (not shown in the figure) sleeved on the radial outside of the outer circumferential wall of the inlet pipe 1, and a driving motor (not shown in the figure), the ring gear is meshed with each driven gear 241 at the same time, and the driving motor is used to drive the ring gear to rotate around the central axis of the inlet pipe 1. The aforementioned driving component can be, for example, a rotary motor, and the aforementioned driven gear 241 can be specifically interference-fitted on the outer end of the rotating shaft 24.

[0055] In this technical solution, by having a ring gear meshing with each driven gear 241 at the same time, only one driving component can be set to drive the ring gear to rotate, thereby realizing the synchronous rotation of each shaft 24, thereby ensuring the synchronous adjustment of the deflection angle of each rotating tail blade 23, with better synchronization, and can reduce the number of driving components used, simplify the structural design, and reduce manufacturing costs.

[0056] As a specific embodiment, the fixing parts of the aforementioned driving components (such as the mounting legs of the motor) can be fixedly connected to the outer wall surface of the pipe wall of the inlet pipe 1, and at the same time, the ring gear and the outer circumference of the pipe wall of the inlet pipe 1 are slidably connected through a corresponding slide rail structure to ensure that the rotation of the ring gear is reliable and stable. The aforementioned slide rail structure can be understood to be annular. For example, a circle of convex rings is provided on the outer wall surface of the inlet pipe 1, and the inner ring surface of the ring gear has an annular groove that slides with the convex ring. Preferably, a ball is provided between the ring wall of the convex ring and the annular groove to reduce sliding friction. At this time, it can be understood that in order to facilitate the assembly connection between the convex ring and the annular groove, the ring gear at this time is assembled from two semicircular arc segments that are symmetrically interlocked with each other.

[0057] In some embodiments, the hub 21 has a central spiral channel 211 running through both ends thereof, and the spiral direction of the central spiral channel 211 is consistent with the swirl direction of the swirl blade 22. In a specific embodiment, the central spiral channel 211 is formed by a spiral plate 212 connected to the central through hole of the hub 21.

[0058] In this technical solution, the hub 21 is objectively designed as a cylindrical structure, and a spiral plate 212 is arranged in its central through hole to form a central spiral channel 211, which can significantly increase the air intake volume of the airflow while reducing the axial size of the parts. More importantly, it strengthens the swirl effect of the stator impeller 2 on the fluid, improves the water separation efficiency and reduces the flow resistance.

[0059] In some embodiments, the cyclone separator further comprises a cyclone water separation pipe 3 and a water collection and drainage pipe 4, wherein the cyclone water separation pipe 3 is connected to the air flow outlet of the inlet pipe 1, and the air flow swirled by the stator impeller 2 enters the cyclone water separation pipe 3, and the liquid water in the air flow is thrown onto the inner wall surface of the cyclone water separation pipe 3 under the action of centrifugal force to form a liquid film, that is, the separation of water from the air flow is completed, and the water collection and drainage pipe 4 is connected to the air flow outlet of the cyclone water separation pipe 3. At this time, the liquid on the inner wall surface of the cyclone water separation pipe 3 Driven by the high-speed airflow, the membrane is brought into the water collection and drainage pipe 4. The pipe flow diameter of the water collection and drainage pipe 4 is not less than the flow diameter of the vortex water distribution pipe 3. In a specific embodiment, the flow diameter of the water collection and drainage pipe 4 first increases and then decreases along the flow direction of the airflow, that is, a cavity structure with a low middle and high ends is formed. In this way, the liquid film can be efficiently collected and discharged here, and at the same time, it can effectively prevent the water collected in the pipe from being further driven into the subsequent pipes.

[0060] As a preferred embodiment, a drain pipe 41 is provided at the bottom of the water collection and drainage pipe 4, through which the water in the water collection and drainage pipe 4 can be promptly drained to a preset location, such as an outdoor environment, a water container, etc.

[0061] In another feasible embodiment, the air flow outlet of the water collecting and drainage pipe 4 is also connected to an air guide duct 5 so as to guide the air flow after heat exchange and dehumidification to the target area. In a preferred embodiment, a water retaining ring 51 is provided in the air flow inlet of the air guide duct 5. The water retaining ring 51 is arranged at the air flow outlet of the water collecting and drainage pipe 4 and the air flow inlet of the air guide duct 5, which can further prevent the collected water in the water collecting and drainage pipe 4 from entering the air guide duct 5 under the action of the high-speed airflow.

[0062] Figures 10 to 12 Flow diagrams of cyclone separators in different states (or technical solutions) are shown in FIG. Fig.10 As shown in the figure, when the central spiral channel is not used, the maximum circumferential velocity at the separator outlet is 16.9 m / s and the pressure loss is 72.9 Pa. After the central spiral channel is used, the maximum circumferential velocity at the separator outlet increases to 18.3 m / s and the pressure loss decreases to 68.4 Pa. Fig.11As shown in the figure, after reducing the blade outlet geometric angle, the maximum circumferential velocity at the separator outlet increases to 21.8 m / s, but the pressure loss increases to 103.4 Pa, as shown in the figure. Fig.12 shown.

[0063] According to an embodiment of the present invention, there is also provided a control method for the above-mentioned cyclone separator, comprising the following steps:

[0064] The humidity of the airflow at the airflow inlet of the inlet pipe 1 is obtained and the change trend of the humidity of the airflow is determined. Specifically, a corresponding humidity sensor is arranged at the airflow inlet of the inlet pipe 1. The humidity sensor samples and detects the real-time humidity of the airflow at a preset time interval, and feeds back to the corresponding control component. The control component compares and determines the magnitudes of the real-time humidity of the two received times. If the current real-time humidity is higher than the latter real-time humidity, it means that the change trend of the airflow humidity is decreasing. Otherwise, if the current real-time humidity is lower than the latter real-time humidity, it means that the real-time change trend of the airflow is increasing. The judgment of the above-mentioned change trend can also be carried out in other feasible ways, which are not listed one by one in the present invention. In principle, all existing methods that can achieve this purpose are acceptable.

[0065] When the change trend of the airflow humidity is increasing, it means that the dehumidification efficiency of the cyclone separator is low and needs to be improved. Therefore, the rotating tail blade 23 can be controlled to rotate toward the side close to the windward surface of the swirl blade 22 to reduce the blade outlet geometric angle. At this time, the resistance of the airflow in the separator is increased, but the water separation effect is greatly improved; or,

[0066] When the changing trend of the air flow humidity is decreasing, it means that the dehumidification efficiency of the cyclone separator is relatively high at this time, and it can be considered to increase the air output while ensuring the dehumidification effect. Therefore, the rotating tail blade 23 can be controlled to rotate toward the side away from the windward surface of the swirl blade 22 to increase the blade outlet geometric angle. At this time, the corresponding resistance of the airflow in the separator is reduced, the loss of the airflow in the separator is small, and the air flow after dehumidification is increased.

[0067] According to an embodiment of the present invention, a heat exchange dehumidification device is also provided, comprising a heat exchanger (not shown in the figure) and the above-mentioned cyclone separator, the air flow inlet of the cyclone separator is connected to the outlet of the heat exchange air flow of the heat exchanger, that is, the cyclone separator can separate the moisture in the air flow after the heat exchange of the heat exchanger, thereby realizing the control and adjustment of the humidity of the heat exchange air flow. A rotating tail blade 23 capable of forming a docking with the swirl blade 22 is arranged on the outflow side of the swirl blade 22, and each rotating tail blade 23 can be driven to rotate a preset angle to change the blade outlet geometric angle of each swirl blade 22, for example, when the humidity of the air flow increases, each rotating tail blade 23 is controlled to rotate to reduce the blade outlet geometric angle, so as to increase the air flow resistance, thereby ensuring the dehumidification effect; and when the humidity of the air flow decreases, each rotating tail blade 23 is controlled to rotate to increase the blade outlet geometric angle, which can reduce the resistance to the air flow, ensure the air flow rate and reduce the air flow loss, so that the rotation direction of the rotating tail blade 23 is controlled to change the blade outlet geometric angle according to different air flow dehumidification requirements, so as to achieve the dehumidification water separation efficiency and flow resistance.

[0068] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention. These improvements and variations should also be regarded as the protection scope of the present invention.
