[0043] The following will be combined with the accompanying 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 embodiments described 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 in no way 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 making creative efforts are within the scope of protection of the present invention.

[0044] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. 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 device or element 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 outline of each component itself.

[0045] 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 of a device or feature to other devices or features as shown in the figures. 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 figures. For example, if the device in the 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" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0046] 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. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0047] See also Figures 1-3 As shown, according to an embodiment of the present invention, a water separator blade 1 is provided, comprising a blade tip 11 for opposing the inner wall of a cylinder 2, a blade root 12 for connecting to a hub 3 within the cylinder 2, an air inlet end 13, and an air outlet end 14. The blade tip 11 of the water separator blade can oppose the inner wall of the cylinder 2 without being connected thereto. In this case, the hub 3 and the cylinder 2 can be fixed via other connecting structures, such as spokes, so that the water separator blade 1 remains relatively fixed to the cylinder 2 via the hub 3. Preferably, the blade tip 11 of the water separator blade is fixedly connected to the inner wall of the cylinder 2, for example, the two can be integrally formed. The blade root 12 of the water separator blade can be fixedly connected to the hub 3, for example, the two can be integrally formed. The water separator blade 1 has a first airfoil profile at the end of the blade tip 11, a second airfoil profile at the end of the blade root 12, and a third airfoil profile at a predetermined point N between the blade tip 11 and the blade root 12.

The surface of the airfoil section 10 is taken as a two-dimensional plane, the first endpoint O is taken as the origin, the OA line is the X-axis direction, and the direction perpendicular to OA is the Y-axis to establish an XOY rectangular coordinate system. The airfoil bone line ML is located in the first quadrant of the rectangular coordinate system, and the length of the line segment OA is L. The inner diameter of the cylinder 2 is R0 (as shown in FIG. Figure 3 shown).

[0049] The distribution curve of the airfoil bone line of the first airfoil section satisfies the following formula (1):

[0050]

[0051] The distribution curve of the airfoil bone line of the second airfoil section satisfies the following formula (2):

[0054]

[0055] like Figure 3As shown, the distance between the end of the blade tip 11 and the axis 31 of the hub is R11, wherein R11 / R0=0.98~1.0, a 61 =-2.05671468816495±0.5, a 51 =4.71007562597028±0.5, a 41 =-4.42155683184833±0.5, a 31 =2.16012004807798±0.5, a 21 =-1.08711103985413±0.5, a 11 =0.695561003927588±0.5, a 01 =0±0.5.

[0056] The distance between the end of the blade root end 12 and the axis 31 of the hub is R12, wherein R12 / R0=0.184-0.224, and a 62 =-9.43329699124488±0.5, a 52 =25.0213865621268±0.5, a 42 =-24.7958862672605±0.5, a 32 =11.1533124771065±0.5, a 22 =-2.24147236942378±0.5, a 12 =0.309783825635101±0.5, a 02 =0±0.5.

[0057] The distance between the preset point N and the axis 31 of the hub is R13, wherein R13 / R0=0.582-0.622, and a 63 =-6.97003691824529±0.5, a 53 =17.5840485425913±0.5, a 43 =-16.7803152619648±0.5, a 33 =7.23820028101756±0.5, a 23 =1.57299164623948±0.5, a 13 =0.505153727503264±0.5, a 03 =0±0.5.

[0058] In the above example, based on aerodynamic theory, by making the airfoil lines ML of the wing sections at the two ends and the middle portion of the water separator blade 1 satisfy the above formula (1), formula (2) and formula (3) respectively, the present application can change the airflow direction at the air outlet end of the water separator blade 1, increase the peripheral velocity component of the airflow at the air outlet end, and facilitate the rotation of the airflow to generate greater centrifugal force to throw the free water droplets in the airflow onto the inner wall of the cylinder 2, thereby improving the water separation efficiency of the water separator.

[0059] For the convenience of understanding, the wing section 10 of the water separator blade 1 is explained below. In combination with the Figure 3 shown, a circle 4 is made with the distance between any point N between the blade tip end 11 and the blade root end 12 and the center axis of the hub 3 as the radius, the circle 4 is taken as a cutting circle, and the cutting circle is extended along the axial direction of the hub 3 to form a cylindrical surface, the curved surface formed by the intersection of the cylindrical surface and the water separator blade 1 is called a primitive stage surface S (as Figure 4 shown). The primitive stage surface S is developed into a two-dimensional planar airfoil along the circumferential direction, and the two-dimensional planar airfoil is the aforementioned wing section 10 (as Figure 5 shown). It should be noted that when the radius of the cutting circle 4 is consistent with R12, the primitive stage surface S formed at this time coincides with the end surface of the blade root end 12. When the radius of the cutting circle 4 is consistent with R11, the primitive stage surface S formed at this time coincides with the end surface of the blade tip end 11.

[0060] In some embodiments, R11 / R0 = 1.0, and a 61 = -2.05671468816495, a 51 = 4.71007562597028, a 41 = -4.42155683184833, a 31 = 2.16012004807798, a 21 = -1.08711103985413, a 11 = 0.695561003927588, a 01 = 0.

[0061] In the above example, when the airfoil line of the first wing section of the water separator blade 1 of the present application satisfies the above values, the airflow direction at the air outlet end of the water separator blade 1 can be further changed, the peripheral velocity component of the airflow at the air outlet end can be increased, and the rotation of the airflow can be facilitated to generate greater centrifugal force to throw the free water droplets in the airflow onto the inner wall of the cylinder 2, thereby improving the water separation efficiency of the water separator.

[0062] In some embodiments, R12 / R0=0.204, and a 62 =-9.43329699124488, a 52 =25.0213865621268, a 42 =-24.7958862672605, a 32 =11.1533124771065, a 22 =-2.24147236942378, a 12 =0.309783825635101, a 02 =0.

[0063] In the above example, when the airfoil bone line of the second airfoil section of the water separator blade 1 of the present invention meets the above value, it can further change the airflow direction of the air outlet end of the water separator blade 1, increase the circumferential velocity component of the airflow at the air outlet end, and help to rotate the airflow to generate greater centrifugal force to throw free water droplets in the airflow onto the inner wall of the cylinder 2, thereby improving the water separation efficiency of the water separator.

[0064] In some embodiments, R13 / R0=0.602, and a 63 =-6.97003691824529, a 53 =17.5840485425913, a 43 =-16.7803152619648, a 33 =7.23820028101756, a 23 =1.57299164623948, a 13 =0.505153727503264, a 03 =0.

[0065] In the above example, when the airfoil bone line of the third airfoil section of the water separator blade 1 of the present invention meets the above value, it can further change the airflow direction of the air outlet end of the water separator blade 1, increase the circumferential velocity component of the airflow at the air outlet end, and help to rotate the airflow to generate greater centrifugal force to throw free water droplets in the airflow onto the inner wall of the cylinder 2, thereby improving the water separation efficiency of the water separator.

[0066] In some embodiments, the three-dimensional curved surface of the water separator blade 1 at the blade tip 11 is taken as the primitive level surface S1, and the three-dimensional curved surface of the water separator blade 1 at the blade root end 12 is taken as the primitive level surface S2. A circle 4 is made with the distance between the aforementioned preset point N and the axis 31 of the hub as the radius, and the circle 4 is extended along the axial direction of the hub 3 to form a cylindrical surface. The three-dimensional curved surface formed by the intersection of the cylindrical surface and the water separator blade 1 is taken as the primitive level surface S3. Among them, the water separator blade 1 can be connected between the primitive level surface S1 and the primitive level surface S3 using a conventional modeling method. Preferably, the primitive level surface S1 and the primitive level surface S3 can be connected by surface blending in a three-dimensional geometric modeling software such as Creo software, which has the effect of convenient connection.

[0067] The water separator blade 1 can be connected between the primitive level surface S2 and the primitive level surface S3 using a conventional modeling method. Preferably, the primitive level surface S2 and the primitive level surface S3 can be connected by a surface blending method in a three-dimensional geometric modeling software such as Creo software, which has a convenient connection effect.

[0068] In some embodiments, as Figure 1 As shown, the air inlet end 13 of the water separator blade has a first edge line 131 , which is a straight line and perpendicularly intersects the axis 31 of the hub, which is beneficial for the air inlet end 13 of the water separator blade to guide the air evenly.

[0069] like Figures 2-3 As shown, the present invention also provides a guide vane structure, which may include any of the above-mentioned water separator blades 1. In which, the guide vane structure adopts the above-mentioned water separator blade 1, and since the shape of the water separator blade 1 is directly related to the airfoil bone lines of the three airfoil sections at both ends (i.e., the aforementioned first airfoil section and the second airfoil section) and the airfoil section at the middle (i.e., the aforementioned third airfoil section), in the above-mentioned example, the present invention is based on aerodynamic theory. By making the airfoil bone lines of the airfoil sections at the two ends and the three places in the middle of the water separator blade 1 satisfy the above-mentioned formulas (1), (2) and (3), it is possible to change the airflow direction at the outlet end of the water separator blade 1, increase the circumferential velocity component of the airflow at the outlet end, and facilitate the rotation of the airflow to generate a greater centrifugal force to throw the free water droplets in the airflow onto the inner wall of the cylinder 2, thereby improving the water separation efficiency of the water separator.

[0070] In some embodiments, the number of the water separator blades 1 may be 3 to 5, and they are evenly arranged in the circumferential direction of the hub 3 .

[0077] It should be noted here that the "inlet flow rate" in the above table refers to the flow rate of the incoming air at the inlet of the aforementioned cylinder 2, and the "inlet moisture content" in the above table refers to the moisture content of the incoming air at the inlet of the aforementioned cylinder 2.

[0078] Among them, by comparing the above tables, it can be seen that the solution of the present invention can greatly improve the water separation efficiency of small-particle droplets under the same working conditions compared with the original technology, with an improvement of about 8%, thereby improving the water separation efficiency of the water separator as a whole, thereby ensuring that it still has a high water separation efficiency under harsh environments.

[0079] like Figures 7-9 As shown, the present invention also provides a water separator, which may include the above-mentioned guide vane structure. The water separator also includes a water separation chamber 5, on which an air inlet pipe 6 and an exhaust pipe 7 are provided. The inlet end 71 of the exhaust pipe is inserted into the outlet 61 of the air inlet pipe, and a gap 601 is provided between the outer wall of the inlet end 71 of the exhaust pipe and the inner wall of the outlet 61 of the air inlet pipe, and the gap 601 is connected to the inside of the water separation chamber 5. The gap 601 can be an annular gap. The water separation chamber 5 is connected to the air outlet end of the cylinder 2 through the inlet of the air inlet pipe 6. A drainage hole 51 is provided on the water separation chamber 5, and the water separator also includes a water collecting tank 9 connected to the drainage hole 51 and a drainage pipe 8 connected to the water collecting tank 9.

[0080] The above-mentioned air inlet pipe 6 can be located at one end of the water diversion chamber 5, and the air inlet pipe 6 is fixedly connected to the water diversion chamber 5, for example, the air inlet pipe 6 can be fixed to the water diversion chamber 5 by means of sub-arc welding. The exhaust pipe 7 can be located at the other end of the water diversion chamber 5, and the exhaust pipe 7 is fixedly connected to the water diversion chamber 5, for example, the exhaust pipe 7 can be fixed to the water diversion chamber 5 by means of sub-arc welding. Among them, the water separator is mainly used to separate the liquid free water in its upstream flow. The outlet end of the above-mentioned cylinder 2 can be fixed to the inlet end of the air inlet pipe 6 by sub-arc welding. The high-speed airflow (flow rate is 10 to 20 m / s) flows into the interior of the cylinder 2 from the inlet of the cylinder 2, and after flowing through the water separator blade 1, a strong rotation speed (about 30 to 40 m / s) is generated (see Figure 11 and Figure 12), the free water droplets in the air, driven by the rotating airflow, generate a large centrifugal force, and then migrate to the wall of the air inlet pipe 6, and form a water film on the inner wall of the air inlet pipe 6. Under the shear force of the main airflow, the water film flows into the water diversion chamber 5 through the aforementioned gap 601. Under the action of gravity and the high pressure difference between the inside and outside (2-4 bar), it flows into the water collection tank 9 through the drainage hole 51 and finally flows out of the drainage pipe. Figure 9 .

[0081] Among them, based on the cyclone separation principle, the present invention invents a high-efficiency water separator, which adopts a strong cyclone water separator blade 1, which greatly improves the rotation speed of the airflow after passing through the water separator blade 1, thereby increasing the centrifugal force, thereby greatly improving the water separation efficiency of the water separator, and can effectively separate the liquid water condensed by the heat exchanger, thereby reducing the moisture content entering the turbine inlet, and finally reducing the ice content at the condenser inlet, thereby reducing the frequency of opening the temperature control valve, thereby increasing its service life.

[0082] The present invention also provides an air cycle machine, which may include any of the above-mentioned water separator blades 1; or include the above-mentioned guide vane structure; or include the above-mentioned water separator. In the air cycle machine, since the above-mentioned water separator blade 1 is used, and since the shape of the water separator blade 1 is directly related to the airfoil skeleton lines of the three airfoil sections at both ends (i.e., the above-mentioned first airfoil section and the second airfoil section) and the airfoil section at the middle (i.e., the above-mentioned third airfoil section), in the above-mentioned example, based on aerodynamic theory, the present invention can change the airflow direction at the outlet end of the water separator blade 1 by making the airfoil skeleton lines of the three airfoil sections at the two ends and the middle of the water separator blade 1 satisfy the above-mentioned formulas (1), (2), and (3) respectively, thereby increasing the circumferential velocity component of the airflow at the outlet end, which is conducive to rotating the airflow, so as to generate a greater centrifugal force to throw the free water droplets in the airflow onto the inner wall of the cylinder 2, thereby improving the water separation efficiency of the water separator.
