Description
Technical Field
The invention relates to the technical field of airborne environmental control, in particular to a longitudinally-arranged high-pressure separator.
Background
When an aircraft flies at high altitude, the dryness and humidity of air in a cabin are key factors to be considered when an on-board environmental control system operates. The high-pressure separator is a machine for separating a two-phase mixture by centrifugal force generated by high-pressure rotational flow, and is often used for separating water in wet air in an airborne environmental control system so as to ensure the dryness of surrounding air when other airborne equipment operates and slow down the aging speed of the equipment.
Currently, gravity is a critical factor to consider based on the design characteristics of the high pressure separator. The ratio of the gas flow direction component speed to the gravity direction component speed is a key index affecting the working efficiency of the high-pressure separator in the airborne equipment. If the high-pressure separator is longitudinally placed, its gravitational component speed will disappear, and a series of problems may occur: the air flow direction speed is increased, free water is not separated and directly enters the downstream, and the water separation efficiency is reduced; the air flow direction dividing speed is reduced, the diameter of free water is increased, the free water cannot completely flow into the water accumulation cavity, and the water dividing efficiency is reduced; free water accumulates in the water accumulation cavity and cannot be rapidly discharged from the water outlet pipe. The long-time longitudinal operation of the high-pressure separator often causes the separation efficiency of the high-pressure separator to be reduced or even the separation function to be lost, meanwhile, according to the working principle of the high-pressure separator, the high-pressure separator is often placed at the lowest end (limited space) of an environmental control system during design so as to be convenient for collecting and discharging free water, and therefore, most high-pressure separators applied to airborne equipment are placed transversely. However, as the requirements of on-board equipment on integration become higher, the strong constraint condition that the high-pressure water separator can only adapt to transverse placement becomes one of the main problems that plague system integration design and pipeline arrangement design.

In this embodiment, in order to ensure that the on-board equipment operates in a relatively dry environment, and to extend the useful life of the on-board equipment, a high pressure separator is required to separate the free water from the wet air so that free water and dry air can be obtained. However, as the requirements of on-board equipment on integration become higher, the strong constraint condition that the high-pressure water separator can only adapt to transverse placement becomes one of the main problems that plague system integration design and pipeline arrangement design. The longitudinally arranged high-pressure separator can better utilize the space region for installing the airborne equipment, so that the space utilization rate is improved, and the pipeline arrangement is facilitated. As shown in fig. 1,2 and 3, the vertical high pressure separator may include a housing assembly 01, a bottom separation assembly 02, a top separation assembly 03, and a cyclone assembly 04. The bottom separation assembly 02, the top separation assembly 03, and the cyclone assembly 04 may be disposed within the housing assembly 01, the bottom separation assembly 02 may be located in a region below the top separation assembly 03, and the cyclone assembly 04 may be disposed in a hollow cavity of the bottom separation assembly 02. The housing assembly 01 may include a housing wall 11, a water accumulation chamber 12, and a water outlet pipe 14. The housing wall 11 may form a closed chamber for receiving the water accumulation chamber 12, the water outlet pipe 14 and other components. The water accumulation cavity 12 can be arranged at the lowest end of the closed cavity of the shell wall body 11, so that separated free water can be quickly converged under the action of gravity, and the subsequent discharge is facilitated. One end of the water outlet pipe 14 can penetrate through the shell wall 11 to be communicated with the water accumulation cavity 12, and the other end of the water outlet pipe can be communicated with the outside, so that free water in the water accumulation cavity 12 can be discharged.

As shown in fig. 3, the bottom separation assembly 02 may include a bottom separation wall unit 21, an air inlet pipe 22. The bottom separation wall unit 21 may have a cylindrical shape with one end opened, and the open end thereof may be upwardly directed so that humid air may rise. The bottom separation wall unit 21 may be disposed in the closed chamber of the housing wall 11 at an upper region of the water accumulation chamber 12. The end of the bottom separating wall unit 21 far away from the opening can be fixedly connected with the end of the outer shell wall body 11 close to the water accumulating cavity 12, so that the bottom separating wall unit 21 can be supported to maintain the distance between the peripheral side wall and the inner side wall of the outer shell wall body 11, and free water can flow into the water accumulating cavity 12. One end of the air inlet pipe 22 may sequentially pass through the side walls of the outer case wall 11 and the bottom separation wall unit 21 so as to communicate with the inner cavity of the bottom separation wall unit 21, so that humid air may enter into the bottom separation wall unit 21 for free water separation. The cross-sectional area of the bottom separation wall unit 21 can be gradually reduced to a certain extent from one end of the bottom separation wall unit 21, which is close to the water accumulation cavity 12, towards the other end and then is kept flat to the open end, so that the volume of the wet air can be compressed in the rising process, and free water in the wet air can be more easily separated after being gathered, thereby improving the water diversion efficiency. The top separation assembly 03 may include a top separation wall 31, an outlet duct 33.

The end of the top separation wall 31 far from the opening can be fixedly connected with the end of the outer shell wall 11 far from the water accumulation cavity 12, so that the position of the top separation wall 31 can be fixed. The open end of the top separation wall 31 may pass through the open end of the bottom separation wall unit 21, and then the open end portion of the top separation wall 31 is made to protrude into the inner cavity of the bottom separation wall unit 21. The cross-sectional area of the open end of the top separation wall 31 may be smaller than that of the open end of the bottom separation wall unit 21, so that a portion of the top separation wall 31 extends into the bottom separation wall unit 21 and may be disposed at a distance from the outer side wall of the open end of the bottom separation wall unit 21 to the inner side wall of the open end of the bottom separation wall unit 21, thereby allowing free water separated by humid air to enter the water accumulation chamber 12. One end of the air outlet pipe 33 may sequentially pass through the side walls of the outer case wall 11 and the top separation wall 31 so as to communicate with the inner cavity of the top separation wall 31, so that dry air after separating free water may be discharged from the air outlet pipe 33. The swirl assembly 04 may include a deflector column 41 and a first deflector 42. The guide post 41 may be disposed in the inner cavity of the bottom separation wall unit 21 and may be located at an upper region of the air inlet pipe 22, the guide post 41 may be disposed at a distance from the bottom separation wall unit 21, and a central axis thereof may coincide with a central axis of the bottom separation wall unit 21. The plurality of first baffle plates 42 may be disposed at intervals along the circumferential direction of the baffle column 41. One end of any first deflector 42 can be fixedly connected with the periphery of the deflector column 41, and the other end can be fixedly connected with the inner side wall of the bottom separation wall unit 21, so that the wet air entering the bottom separation wall unit 21 from the air inlet pipe 22 can rise in an accelerating and rotating way under the guiding action of the cyclone component 04, and the water diversion efficiency is improved. Any one of the first baffle plates 42 may extend obliquely upward from one end thereof adjacent to the baffle column 41 toward the other end thereof, so that adjacent first baffle plates 42 may form a plurality of swirl passages in the bottom separation wall unit 21, facilitating the guiding of the humid air to rise rotationally. The central axis of intake pipe 22 can set up with the central axis interval of whirl subassembly 04 for intake pipe 22 can eccentric setting be close to the one end lateral wall of ponding chamber 12 at end separating wall unit 21, thereby can make the moist air that gets into in the end separating wall unit 21 can rise along the inside wall rotation of end separating wall unit 21 rapidly, improves water diversion efficiency. Through the arrangement of the inner parts of the vertical high-pressure separator, the volume of the vertical high-pressure separator can be reduced, and the limited space is effectively utilized.

The bottom wall 211, the tapered side wall 212, and the straight side wall 213 may be fixedly connected in order, so that an inner cavity of the bottom separation wall unit 21 may be formed. The bottom wall 211 may be tapered, and the cross-sectional area thereof may gradually increase from one end of the bottom wall 211 near the tapered side wall 212 toward the other end, and the maximum cross-sectional area of the other end may be the same as the maximum cross-sectional area of the tapered side wall 212, so that the moisture air retained on the inner side wall of the bottom separation wall unit 21 during the separation process may be collected to the bottom wall 211 by gravity. The tapered side wall 212 may be tapered, and its cross-sectional area may gradually decrease from one end of the tapered side wall 212 near the bottom wall 211 toward the other end, and the minimum cross-sectional area of the other end may be the same as the cross-sectional area of the straight side wall 213, so that the volume of the wet air in the separation process is gradually compressed, and free water in the wet air is collected and then quickly separated, so as to improve the water diversion efficiency.
