Description

Technical Field

[0001] This invention belongs to the field of solid-state attitude control technology, specifically relating to a gas-liquid separation device for gas storage under high temperature, high pressure and zero gravity. Background Technology

[0002] Solid propulsion attitude control engines are characterized by simple structure, high safety, good performance, small size, long storage period, and convenient maintenance and use. In gas-powered solid propulsion attitude control systems, the gas generator produces high-temperature, high-pressure gas, which melts the metal in the propellant grain into a liquid. This results in the presence of liquid metal particles in the high-temperature, high-pressure gas generated under gravity conditions. When this high-temperature, high-pressure gas enters the downstream pressure reducing valve and solenoid valve, these liquid metal particles may cause malfunctions. Therefore, it is necessary to separate the liquid metal particles from the high-temperature, high-pressure gas.

[0003] Currently, gas-liquid separators employ various separation structures and methods, including gravity settling, baffle separation, centrifugal separation, wire mesh separation, ultrafiltration, and packing separation. However, existing filtration technologies struggle to filter metallic liquid particles from high-temperature, high-pressure gases under gravity-free conditions, while simultaneously ensuring the gas flow path and weight.

[0005] To achieve the above objectives, the present invention provides a gas-liquid separation device for high temperature and high pressure under zero gravity, used to separate metal liquid particles from high temperature and high pressure gas under zero gravity. It includes a single-necked gas cylinder, a double-necked gas cylinder and a three-way connector. The three-way connector includes a first connector, a second connector and a third connector. The first connector and the third connector are arranged on the same axis and form a certain angle with the axis of the second connector. The first connector is coaxially connected to the opening of the single-necked gas cylinder, the second connector is coaxially connected to the inlet of the double-necked gas cylinder, and the third connector is connected to the pipeline for inputting the gas-liquid mixture.

[0006] As a further improvement of the present invention, a converter tube is provided inside the single-port gas cylinder.

The baffle can rotate around the rotating shaft to close or open the port of the converter tube, and a plurality of first small holes are provided on the tube wall of the converter tube.

[0007] As a further improvement of the present invention, the angle formed between the baffle and the end face of the converter tube when the baffle is open does not exceed 65°; And / or, The opening of the first small hole faces the side where the opening of the single-port gas cylinder is located.

[0008] As a further improvement of the present invention, the angle formed by the axis of the first connector and the axis of the second connector is not less than 90°.

[0009] As a further improvement of the present invention, a collection bottle is provided inside the dual-necked gas cylinder, and the collection bottle is connected to the inlet of the dual-necked gas cylinder through a collection tube, and a plurality of second small holes are provided on the wall of the collection tube.

[0010] As a further improvement of the present invention, the collecting tube is provided with a constriction section between the second small hole and the inlet of the double-mouth gas cylinder, and the diameter of the constriction section is smaller than the diameter of the collecting tubes on both sides of the constriction section.

[0011] As a further improvement of the present invention, the opening of the second small hole faces the side away from the inlet of the double-mouth gas cylinder; And / or, The volume of the collection bottle does not exceed 2% of the volume of the single-point gas cylinder.

[0012] As a further improvement of the present invention, the second connector of the three-way connector is connected to the opening of the single-necked gas cylinder through a ball connector; And / or, The third connector of the three-way connector is connected to the inlet of the two-way gas cylinder via a ball joint.

[0013] As a further improvement of the present invention, a guide tube is provided at the outlet of the dual-necked gas cylinder.

[0014] As a further improvement of the present invention, the single-necked gas cylinder and / or the double-necked gas cylinder are made of titanium alloy material.

[0015] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0016] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include: (1) The gas-liquid separation device for high temperature and high pressure under zero gravity includes a single-necked gas cylinder, a double-necked gas cylinder and a three-way connector. It connects two connectors on the same axis of the three-way connector to the single-necked gas cylinder and the pipeline for inputting the gas-liquid mixture, respectively, and connects the remaining connector not on the axis to the inlet of the double-necked gas cylinder. After the gas-liquid mixture in the zero gravity environment enters the three-way connector from the pipeline, the larger liquid particles move into the single-necked gas cylinder located on the same axis due to inertia, while the smaller gas particles enter the single-necked gas cylinder along with the liquid particles, and the other part enters the double-necked gas cylinder from the other connector, thereby realizing the separation of the gas-liquid mixture.

[0017] (2) The gas-liquid separation device for high temperature and high pressure under zero gravity of the present invention is provided with a converter tube connected to the opening inside a single-port gas cylinder, and a baffle connected by a rotating shaft is provided at the end of the converter tube. A first small hole is made on the wall of the converter tube. When the single-port gas cylinder is in the gas inlet, the airflow impacts the baffle to open the port of the converter tube, and the larger liquid droplets in the gas-liquid mixture enter the bottom of the single-port gas cylinder. When the gas is exhausted, the airflow impacts the outside of the baffle to close the port of the converter tube. The gas in the gas-liquid mixture can flow out from the first small hole, while the liquid particles remain in the single-port gas cylinder, thereby realizing the separation of the gas-liquid mixture during the exhaust process.

[0018] (3) The gas-liquid separation device under high temperature, high pressure and zero gravity of the present invention is provided with a collection bottle in a double-necked gas cylinder and the collection bottle is connected to the inlet of the double-necked gas cylinder by a collection pipe. The collection pipe has a second small hole on its wall, so that during the gas intake process of the double-necked gas cylinder, the small liquid particles that the gas in the double-necked gas cylinder may carry may enter the collection bottle along the collection pipe under the action of inertia, and the gas enters the double-necked gas cylinder from the second small hole of the collection pipe, thereby achieving further separation of the gas-liquid mixture.

[0019] (4) The gas-liquid separation device for high temperature and high pressure under zero gravity of the present invention has a constriction section provided in the part of the collection tube between the second small hole and the inlet of the double-necked gas cylinder. The diameter of the constriction section is smaller than the diameter of the collection tube on both sides of the constriction section, so that the gas flow entering the collection tube forms a concentrated bundle. The small liquid particles are concentrated in the center of the collection tube, away from the tube wall, and enter the collection bottle along the collection tube, so as to prevent the small liquid particles from entering the double-necked gas cylinder from the second small hole on the tube wall of the collection tube, so that the gas in the double-necked gas cylinder maintains a high purity.

[0020] (5) The gas-liquid separation device under high temperature and high pressure and gravity of the present invention separates the gas-liquid mixture in the gravity environment into two gas cylinders for storage by changing the flow channel and using the inertial force of the liquid particles themselves. The single-necked gas cylinder contains the gas-liquid mixture, while the double-necked gas cylinder contains the gas. During the exhaust process, the liquid particles in the gas discharged from the single-necked gas cylinder are further separated by the setting of the exchange pipe, which effectively realizes the separation of the gas-liquid mixture, leaves the liquid particles in the single-necked gas cylinder, and then delivers the gas with higher purity to the downstream device from the outlet of the double-necked gas cylinder.

[0028] Example: The gas-liquid separation device under high temperature and high pressure and gravity in the preferred embodiment of the present invention is used to separate metal liquid particles from high temperature and high pressure gas under gravity, and can also store high temperature and high pressure gas.

[0029] Please see Figures 1-6 The gas-liquid separation device for high temperature, high pressure, and zero gravity under the action of gas storage in the preferred embodiment of the present invention includes a single-necked gas cylinder 11, a double-necked gas cylinder 21, and a three-way connector 3. The three-way connector 3 includes a first connector 31, a second connector 32, and a third connector 33. The first connector 31 and the third connector 33 are arranged on the same axis, forming a certain angle with the axis of the second connector 32. Further, the first connector 31 is coaxially connected to the opening of the single-necked gas cylinder 1, the second connector 32 is coaxially connected to the inlet of the double-necked gas cylinder 21, and the third connector 33 is connected to the pipe 4 for inputting the gas-liquid mixture. Specifically, the single-necked gas cylinder 11, as the name suggests, is a gas cylinder with only one opening, where the inlet and outlet are the same; the double-necked gas cylinder 21 is a gas cylinder with two openings, one for the inlet and the other for the outlet. Furthermore, the gas-liquid mixture is a mixture of high-temperature, high-pressure gas and liquid metal particles, wherein the mass of the liquid metal particles preferably accounts for no more than 10% of the total mass of the gas-liquid mixture.

[0030] The gas-liquid separation process of this device is as follows: High-temperature, high-pressure gas containing liquid metal particles enters the third connector 33 of the tee connector 3 from pipe 4. Larger liquid metal particles, due to inertia, move towards the first connector 31 located on the same axis and enter the bottom of the single-necked gas cylinder 11 through its opening. A portion of the lighter gas, due to inertia, enters the single-necked gas cylinder 11 along with the liquid metal particles, while the other portion flows out from the second connector 32 and enters the double-necked gas cylinder 21. This device, by changing the flow path and utilizing the inertial force of the liquid metal particles themselves, separates the gas-liquid mixture in a weightless environment into two gas cylinders for storage, leaving the liquid particles in the mixture in the single-necked gas cylinder 11, resulting in high reliability.

[0031] Preferably, the angle formed by the axis of the first connector 31 and the axis of the second connector 32 is not less than 90°, so that the metal liquid particles in the gas-liquid mixture need to overcome a turning angle of at least 90° to flow from the third connector 33 to the second connector 32 (i.e., into the double-necked gas cylinder 21), thus preventing the metal liquid particles from entering the double-necked gas cylinder 21 with part of the gas flow.

[0032] Preferably, the angle formed by the axis of the first connector 31 and the axis of the second connector 32 is not greater than 135°, that is, the angle between the axis of the double-mouth gas cylinder 21 and the pipeline 4 is not less than 45°, so that the whole assembly of the various parts of the device is more compact, avoiding excessive space occupation, and reserving a certain space for other equipment or devices at the end of the pipeline 4 away from the tee connector 3.

[0033] More preferably, a converter tube 12 is provided inside the single-port gas cylinder 11. One end of the converter tube 12 is connected to the opening of the single-port gas cylinder 11, and the other end is provided with a baffle 14 connected to the converter tube 12 via a rotating shaft 13. The baffle 14 can rotate around the rotating shaft 13 to close or open the port of the converter tube 12, and a plurality of first small holes 121 are provided on the tube wall of the converter tube 12.

[0034] Specifically, the process of the gas-liquid mixture entering the single-necked gas cylinder 11 is as follows: high-temperature and high-pressure gas containing metal liquid particles enters the single-necked gas cylinder 11. The gas flow impacts the baffle 14 inside the converter tube 12 and rotates around the shaft 13 to open it, opening the port of the converter tube 12. Under the action of inertia, the larger metal liquid particles enter the bottom of the single-necked gas cylinder 11 from the port of the converter tube 12. Part of the high-temperature and high-pressure gas enters the single-necked gas cylinder 11 from the port, and another part enters the single-necked gas cylinder 11 from the first small hole 121 on the tube wall of the converter tube 12 and stays near the opening of the single-necked gas cylinder 11. Furthermore, the process of high-temperature and high-pressure gas being discharged from the single-port gas cylinder 11 is as follows: the gas flow impacts the baffle 14 inside the single-port gas cylinder 11 and rotates around the shaft 13 to close the port of the converter pipe 12. At this time, the larger metal liquid particles are sealed inside the single-port gas cylinder 11, and the high-temperature and high-pressure gas inside the single-port gas cylinder 11 flows into the converter pipe 12 through the first small hole 121 on the pipe wall of the converter pipe 12 and is discharged from the opening of the single-port gas cylinder 11, thus realizing the separation of metal liquid particles from the high-temperature and high-pressure gas during the exhaust process.

[0035] In a preferred embodiment, the angle formed between the baffle 14 and the end face of the converter pipe 12 when the baffle 14 is open α No more than 65°, such as Figure 6 As shown, when the airflow in the single-port gas cylinder 11 is discharged, it impacts the baffle 14 along the airflow direction, moving it away from the outer surface of the converter pipe 12, and causes the baffle 14 to rotate around the pivot 13, thus closing the port of the converter pipe 12. If the baffle 14 is open, the angle formed between it and the end face of the converter pipe 12... α Too large, for example α When the angle is greater than or equal to 90°, the airflow is unlikely to impact the outer surface of the baffle 14 when it exits the single-port gas cylinder 11, causing it to rotate around the shaft 13 to the port of the closed converter tube 12. At this time, the metal liquid particles will flow out from the port of the converter tube 12 with the airflow, so that the discharged high-temperature and high-pressure gas still contains a lot of metal liquid particles.

[0036] In specific settings, such as Figure 4 As shown, a fixed base 16 is preferably fixedly connected to the outer side of the converter pipe 12. The baffle 14 is connected to the fixed base 16 via a rotating shaft 13. A limit sleeve 15 is preferably provided at the end of the rotating shaft 13 to prevent relative displacement between the rotating shaft 13 and the fixed base 16. In this preferred embodiment, the fixed base 16 can limit the rotation of the baffle 14. When the baffle 14 rotates around the rotating shaft 13 until the end of the baffle 14 abuts against the end of the fixed base 16, this is the maximum opening range of the baffle 14. Figure 6 As shown.

[0037] Preferably, the opening of the first small hole 121 faces the side where the opening of the single-necked gas cylinder 11 is located. When the high-temperature and high-pressure gas is discharged from the single-necked gas cylinder 11, the metal liquid particles at the bottom of the single-necked gas cylinder 11 move with the airflow toward the opening of the single-necked gas cylinder 11. At this time, if the metal liquid particles want to flow into the first small hole 121, they need to overcome a large turning angle. Therefore, the metal liquid particles with larger mass will move along the original direction of motion toward the opening of the single-necked gas cylinder 11 under the action of inertia and remain inside the single-necked gas cylinder 11.

[0038] Preferably, the angle between the orifice of the first small hole 121 and the axis of the converter tube 12 is 45°~60°.

[0039] Preferably, the total area of ​​all the first small holes 121 is greater than the area of ​​the internal channel of the converter tube 12, so as to prevent the airflow inside the converter tube 12 from being blocked.

[0040] More preferably, a collection bottle 22 is provided inside the double-necked gas cylinder 21. The collection bottle 22 is connected to the inlet of the double-necked gas cylinder 21 through a collection pipe 23. A plurality of second small holes 231 are provided on the wall of the collection pipe 23.

[0041] During the actual intake process, smaller metal liquid particles may enter the double-necked gas cylinder 21 along with the high-temperature and high-pressure gas under the action of the airflow. At this time, the metal liquid particles will move towards the collection bottle 22 along the direction of the collection tube 23 under the action of inertia and remain in the collection bottle 22, while the high-temperature and high-pressure gas can flow into the double-necked gas cylinder 21 from the second small hole 231 on the wall of the collection tube 23. During the exhaust process, the high-temperature and high-pressure gas in the single-necked gas cylinder 11 flows into the double-necked gas cylinder 21 from the collection tube 23, which will block the metal liquid particles in the collection bottle 22 from flowing into the double-necked gas cylinder 21 from the collection tube 23. Therefore, the gas discharged from the outlet of the double-necked gas cylinder 21 is a high-purity high-temperature and high-pressure gas with separated metal liquid particles.

[0042] Preferably, the second small hole 231 faces away from the inlet of the double-necked gas cylinder 21, so that the metal liquid particles in the collection bottle 22 need to overcome a large turning angle to enter the second small hole 231 of the collection tube 23. Therefore, during the gas storage process, the metal liquid particles in the collection bottle 22 are also difficult to enter the double-necked gas cylinder 21.

[0043] Preferably, the angle between the orifice of the second small hole 231 and the axis of the collecting tube 23 is 45° to 60°.

[0044] Preferably, the total area of ​​all the second holes 231 is greater than the area of ​​the internal channel of the collecting tube 23, so as to prevent the airflow inside the collecting tube 23 from becoming blocked.

[0045] More preferably, a constriction section 232 is provided between the second small hole 231 and the inlet of the double-necked gas cylinder 21 in the collecting tube 23. The diameter of the constriction section 232 is smaller than the diameter of the collecting tube 23 on both sides of the constriction section 232. In this preferred embodiment, when the high-temperature and high-pressure gas passes through this constriction section 232, it can form a more concentrated airflow, which concentrates the contained metal liquid particles to the center of the collecting tube 23, separates them from the tube wall of the collecting tube 23, and moves them along the collecting tube 23 into the collecting bottle 22.

[0046] Preferably, the volume of the collection bottle 22 does not exceed 2% of the volume of the single-necked gas cylinder 11. In this case, the volume of the single-necked gas cylinder 11 is much larger than the volume of the collection bottle 22. When the device of the present invention exhausts gas, the gas flowing into the double-necked gas cylinder 21 from the collection pipe 23 is mainly the gas from the single-necked gas cylinder 11, which will block the metal liquid particles in the collection bottle 22 from flowing into the double-necked gas cylinder 21 from the collection pipe 23.

[0047] Preferably, the first connector 31 of the three-way connector 3 is connected to the opening of the single-necked gas cylinder 11 via the ball connector 5, such as... Figure 1 As shown, the ball joint 5 is preferably connected to the opening of the single-port gas cylinder 11 through the slip-fit ​​nut 6. The ball joint is suitable for connecting pipelines in high temperature and high pressure environments and occupies less space.

[0048] Similarly, the second connector 32 of the tee connector 3 is preferably connected to the inlet of the double-necked gas cylinder 21 via a ball connector, and the ball connector is preferably connected to the inlet of the double-necked gas cylinder 21 via a slip-on nut.

[0049] In another preferred embodiment, the first connector 31 of the tee connector 3 can also be connected to the opening of the single-port gas cylinder 11 via a graphite ring and a flange; the second connector 32 of the tee connector 3 can also be connected to the inlet of the double-port gas cylinder 21 via a graphite ring and a flange.

[0050] Preferably, a guide pipe 24 is provided at the outlet of the dual-mouth gas cylinder 21, and when the device of the present invention exhausts gas, the high-temperature and high-pressure gas flows out from the guide pipe 24.

[0051] Preferably, pipe 4 is a one-way channel used to transport the gas-liquid mixture into the device of the present invention during the air intake process, and during the exhaust process, the gas cannot flow out of pipe 4. In another preferred embodiment, pipe 4 is provided with a valve, which opens when the gas-liquid separation device of the present invention is intake and closes when exhausting.

[0052] In a preferred embodiment, the end of the pipe 4 furthest from the tee joint 3 is connected to the gas generator to transport the gas-liquid mixture generated by the gas generator to the gas-liquid separation device of the present invention; the guide pipe 24 is connected to the pressure reducing valve and the solenoid valve downstream of the device to transport the filtered high-purity high-temperature and high-pressure gas to the pressure reducing valve and the solenoid valve for operation, effectively protecting the operation of the pressure reducing valve and the solenoid valve downstream of the system.

[0053] Preferably, the duration of each air intake process in this gas-liquid separator does not exceed 1 second.

[0054] Preferably, the single-necked gas cylinder 11 and / or the double-necked gas cylinder 21 are made of titanium alloy, which has high strength at high temperatures and can withstand a pressure of 35 MPa at a temperature of 350°C. It can effectively store high-temperature and high-pressure gases, while being lightweight overall.

[0055] The high-temperature, high-pressure, zero-gravity gas-liquid separation device of this invention includes a single-necked gas cylinder, a double-necked gas cylinder, and a three-way connector. The three-way connector connects two connectors on the same axis to the single-necked gas cylinder and the pipeline through which the gas-liquid mixture enters, respectively. The remaining connector, not on the same axis, is connected to the inlet of the double-necked gas cylinder. When the gas-liquid mixture in the zero-gravity environment enters the three-way connector from the pipeline, the larger liquid particles move towards the single-necked gas cylinder on the same axis due to inertia, while the smaller gas particles partially enter the single-necked gas cylinder along with the liquid particles, and the remaining portion enters the double-necked gas cylinder through the other connector, thus achieving gas-liquid separation. This device, by changing the flow path and utilizing the inertial force of the liquid particles themselves, separates the gas-liquid mixture in a zero-gravity environment into two gas cylinders for storage. The single-necked gas cylinder contains the gas-liquid mixture, while the double-necked gas cylinder contains the gas, effectively achieving gas separation within the gas-liquid mixture.

[0056] Those skilled in the art will readily understand that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
