Description

Technical Field

[0001] The invention belongs to the technical field of water separators, and in particular relates to a water separator blade, a guide vane structure, a water separator and an air cycle machine. Background Art

[0002] As one of the core components of the ACU (air conditioning system), the water separation performance of the water separator directly affects the ice blockage at the turbine outlet of the ACM (air cycle machine) and the cold side inlet of the condenser. In order to ensure the stable operation of the ACM, the opening frequency of the TCV (temperature control valve) needs to be increased, which in turn affects its service life. In addition, the water separation efficiency of the water separator also affects the water content at the ACU outlet (water vapor in gaseous form and ice residue in solid form), which in turn affects the moisture content of the downstream gas, and ultimately affects the safety of the aircraft avionics. The resistance of the water separator will affect the inlet pressure of its downstream turbine, and thus affect the operating speed and outlet temperature of the entire ACU (air conditioning system) system. It can be seen that the water separation efficiency of the water separator is crucial, and how to improve the water separation efficiency of the water separator has become a technical problem that technicians in this field need to solve.

[0043] 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.

[0044] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the 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 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.

[0045] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here 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" 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. 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.

[0047] See also Figure 1-3 As shown, according to an embodiment of the present invention, a water separator blade 1 is provided, which includes a blade tip 11 for being opposite to the inner wall of the cylinder 2, a blade root end 12 for being connected to the hub 3 in the cylinder 2, an air inlet end 13 and an air outlet end 14. The blade tip 11 of the water separator blade can be opposite to the inner wall of the cylinder 2, and the two are not connected. In this case, the hub 3 and the cylinder 2 can be fixed by other connecting structures such as spokes, so that the water separator blade 1 can be relatively fixed to the cylinder 2 through 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 connected in an integral manner. The blade root end 12 of the water separator blade can be fixedly connected to the hub 3, for example, the two can be connected in an integral manner. The water separator blade 1 has a first wing section at the end of the blade tip 11, a second wing section at the end of the blade root end 12, and a third wing section at a preset point N between the blade tip 11 and the blade root end 12.

[0048] like Figure 5-6 As shown, the midline of the airfoil section 10 of the water separator blade 1 is defined as the airfoil bone line ML, and the airfoil bone line ML has a first endpoint O at the air inlet end 13 and a second endpoint A at the air outlet end 14. The surface where the airfoil section 10 is located 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 (such as Figure 3 shown).

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

[0050]

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

[0052]

[0053] The distribution curve of the airfoil bone line of the third wing section satisfies the following formula (3):

[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, where 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] Among them, since the shape of the water separator blade 1 is directly related to the airfoil skeleton line ML of the airfoil sections at both ends (i.e., the aforementioned first airfoil section and the second airfoil section) and the airfoil section in the middle (i.e., the aforementioned third airfoil section), in the above example, the present invention is based on aerodynamic theory. By making the airfoil skeleton lines ML of the airfoil sections at the two ends and the three places in the middle of the water separator blade 1 satisfy the above formulas (1), (2) and (3) respectively, the airflow direction at the outlet end of the water separator blade 1 can be changed, and the circumferential velocity component of the airflow at the outlet end can be increased, which is conducive to rotating the airflow to generate a larger 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 ease of understanding, the airfoil section 10 of the water separator blade 1 is explained below. Figure 3 As shown in FIG. 1 , a circle 4 is made with the distance between any point N between the blade tip 11 and the blade root 12 and the central 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 the elementary level surface S (such as Figure 4 As shown), the primitive level surface S is expanded circumferentially to form a two-dimensional plane airfoil, which is the aforementioned airfoil section 10 (as shown in FIG. Figure 5 It should be noted that when the radius of the cutting circle 4 is consistent with R12, the elementary level 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 elementary level surface S formed at this time coincides with the end surface of the blade tip 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 bone line of the first airfoil section of the water separator blade 1 of the present invention satisfies the above value, it can further 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 help rotate 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.

[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 at 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 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.

[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 at 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 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.

[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 by conventional modeling methods. Preferably, the primitive level surface S1 and the primitive level surface S3 can be connected by surface mixing 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 by conventional modeling methods. Preferably, the primitive level surface S2 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 a convenient connection effect.

[0068] In some embodiments, 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 conducive to uniform air guidance of the air inlet end 13 of the water separator blade.

[0069] like Figure 2-3 As shown, the present invention further provides a guide vane structure, which may include any of the above-mentioned water separator blades 1. Wherein, because the guide vane structure adopts the above-mentioned water separator blade 1, and because the shape of the water separator blade 1 is directly related to the airfoil bone lines of the airfoil sections at both ends (i.e., the aforementioned first airfoil section and the second airfoil section) and the airfoil section in the middle (i.e., the aforementioned third airfoil section), in the above-mentioned example, the present invention is based on aerodynamic theory, and 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 help the airflow to rotate, 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.

[0074] Effect of the present invention

[0075]

[0076]

[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 table, 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 in harsh environments.

[0079] like Figure 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 air 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 may 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 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 sub-arc welding. Among them, the water separator is mainly used to separate 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 blades 1, a strong rotation speed (about 30 to 40 m / s) is generated (see Fig.11 and Fig.12), the free water droplets in the air generate a large centrifugal force driven by the rotating airflow, and then migrate to the pipe 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, and 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 from the drainage pipe, as shown in FIG. Fig. 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. Among them, because the air cycle machine adopts the above-mentioned water separator blade 1, and because the shape of the water separator blade 1 is directly related to the airfoil bone lines of the airfoil sections at both ends (i.e., the above-mentioned first airfoil section and the second airfoil section) and the airfoil section in the middle (i.e., the above-mentioned third airfoil section), in the above-mentioned example, the present invention is based on aerodynamic theory, and 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 formula (1), formula (2) and formula (3) respectively, it can 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 help to rotate 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.

[0083] 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.
