Description

Technical Field

[0001] The present invention relates to the field of high-pressure turbines, and in particular to a driven cone turbine and a high-pressure turbine mechanism for a green-ring air conditioner. The invention is primarily used in applications such as green-ring air conditioners that require the conversion of high-pressure air energy into other energies. Background Art

[0002] The "Green Ring Air Conditioning" projects with patent application numbers 2021113567369, 2021113580630, and 2021113567373 have passed simulation and mathematical research at Tsinghua University (R&D reports can be provided).

[0003] After equipping the "Green Ring Air Conditioning" project with its high-pressure turbine mechanism and conducting mathematical research, we found that:

[0004] 1) A high-pressure turbine mechanism compatible with the Green Ring Air Conditioner structure could not be found. If the existing high-pressure turbine mechanism must be used, the Green Ring Air Conditioner structure would need to be significantly modified, which would go against the original intention and would not be worth the effort.

[0005] 2) Due to the first reason, the original "Green Ring Air Conditioner" design adopted existing general technology and designed a dedicated high-pressure turbine mechanism based on the characteristics of the "Green Ring Air Conditioner". However, the energy conversion efficiency remained at the current level:

[0006] The efficiency of converting gas energy into mechanical energy in the "high-pressure turbine" at the front end of the high-pressure turbine mechanism is generally around 75%. The main energy losses are gas leakage and impact between the turbine and the casing, which accounts for approximately -15%, tail vortex, which accounts for approximately -5%, and other losses, which account for approximately -5%. The efficiency of converting gas energy into mechanical energy in the "driven turbine" at the rear end of the high-pressure turbine mechanism is also generally around 75%. Therefore, the overall energy conversion rate of the high-pressure turbine mechanism is approximately 0.75 * 0.75 = 56%.

[0007] The above research findings indicate that, without sacrificing structural modifications to the Green Ring Air Conditioner, using an existing high-pressure turbine mechanism on the market would be an undesirable option. However, these are unavailable and their efficiency is unsatisfactory. After comprehensive consideration, it is imperative to develop an advanced high-pressure turbine mechanism suitable for the Green Ring Air Conditioner. The high-pressure turbine mechanism consists of a gas-powered turbine at the front and a driven turbine at the rear, both of which require improved energy conversion efficiency.

[0019] Beneficial effects

[0020] Compared with the prior art, the advantages of the driven cone turbine and the green ring air-conditioning high-pressure turbine mechanism of the present invention are:

[0021] 1. For the gas-powered cone turbine in the Green Ring air conditioner's high-pressure turbine mechanism, high-pressure gas enters the pressure relief accelerator tube through an electronically controlled valve. After passing through the high-pressure gas nozzle at a velocity of V1, it is compressed and accelerated to V2 and injected into the impact turbine's impeller, driving the high-pressure pneumatic cone turbine. The motive gas forms a vortex within the turbine cone body, decelerated by the first swirl-reducing fin, then further decelerated by the second swirl-reducing fin before being discharged from the high-pressure pneumatic cone turbine's exhaust port. Due to the exhaust port's small diameter, the swirl energy of the airflow it generates is minimal, eliminating the need for a reverse jet mechanism at the tail end.

[0022] 2. Since the conical volute is fixed, and the pneumatic conical pot turbine rotates rapidly, it is a difficult problem to prevent gas leakage from the micro-gap between the conical volute and the pneumatic conical pot turbine and to reduce the friction loss between them. For this reason, two polytetrafluoroethylene (PTFE) rings are specially set between the conical volute and the high-pressure pneumatic conical pot turbine, and lubricating oil is injected, which can play a good role in preventing leakage and reducing friction loss. The two polytetrafluoroethylene (PTFE) rings can greatly increase the flow resistance of the air, and at the same time, the presence of lubricating oil makes air leakage extremely small. The polytetrafluoroethylene ring has excellent self-lubricating function and excellent performance in terms of temperature resistance, wear resistance, strength, etc. In addition, the presence of lubricating oil makes the friction loss between the second conical volute and the high-pressure pneumatic conical pot turbine, and between the first conical volute and the pneumatic conical pot turbine extremely small.

[0023] 3. As the high-pressure gas energy of the gas-powered cone turbine of the high-pressure turbine mechanism of the Green Ring air conditioner enters the high-pressure pneumatic cone turbine, its energy mainly goes to: the rotational mechanical energy of the high-pressure pneumatic cone turbine and the kinetic energy of the exhaust gas. After passing through the first and second swirl-reducing ribs, the exhaust gas energy is extremely low, so the energy is basically converted into the rotational mechanical energy of the high-pressure pneumatic cone turbine, reducing energy loss. Therefore, the energy conversion rate of the gas-powered cone turbine can reach about 90%.

[0024] 4. In the driven conical turbine, air is drawn in at a velocity of V4 by the turbine's intake vortex blades, pressurized and accelerated to V5 by the integrated impeller, then enters the conical cavity, forming a vortex. This vortex is then ejected by the turbine's centrifugal impeller into the vortex nozzle, forming a pressurized airflow at a velocity of V6. This pressurized airflow passes through the compression vortex and the one-way cone valve and is then pumped into the warm and pressurized chamber at a velocity of V7. Throughout this process, the air is pressurized at three stages: the turbine's intake vortex blades, the integrated impeller, and the turbine's centrifugal impeller. As a result, the driven conical turbine achieves an energy conversion efficiency of approximately 90%.

[0025] 5. The Green Ring air conditioner's high-pressure turbine mechanism is specifically designed, making it ideally suited for Green Ring air conditioners in terms of both structure and technical performance. This mechanism converts energy by transferring gas into the conical turbine body, eliminating the two major energy loss issues encountered in existing technologies: gas leakage and impact between the turbine and casing, as well as tail vortexes. Three-stage energy absorption and conversion within the first conical turbine body achieves a reduced mechanism size, higher efficiency, and lower noise. Theoretically, the Green Ring air conditioner's high-pressure turbine mechanism can achieve an overall energy efficiency of approximately 80%.

[0057] The first conical volute 1 includes a first conical pot housing 121 that rotatably engages with the first turbine cone body 24. A first sealing ring 6 is provided between the inner end surface of the first conical pot housing 121 and the outer end surface of the first turbine cone body 24. The first sealing ring 6 is a polytetrafluoroethylene ring. In this embodiment, the outer end surface of the first turbine cone body 24 is perpendicular to the axis of the turbine power input shaft 21. Two concentrically arranged first semicircular annular grooves 241 of different diameters are provided on the outer end surface of the first turbine cone body 24. The inner end surface of the first conical pot housing 121 is perpendicular to the axis of the turbine power input shaft 21 and is arranged directly opposite the outer end surface of the first turbine cone body 24.

[0061] like Figure 1 The figure shows a green ring air conditioning high pressure turbine mechanism, including a gas powered cone turbine and a driven cone turbine, wherein the structure of the gas powered cone turbine is as shown in FIG. Figure 13-23As shown. The gas-powered conical turbine includes a second conical volute 7 and a high-pressure pneumatic conical turbine 8 that are rotatably connected to each other. A cavity 74 for accommodating the conical turbine is provided in the second conical volute 7, and a pressure relief acceleration tube 71 is provided on the second conical volute 7, which is tangentially connected to the cavity 74 for accommodating the conical turbine. The high-pressure pneumatic conical turbine 8 includes a turbine power output shaft 81, on which a turbine impact impeller 82, a second turbine conical body 85, and an exhaust port 86 are provided in sequence along the axial direction, and the middle parts of the three are connected in sequence along the airflow direction. A first swirl-reducing rib 87 is also provided in the second turbine conical body 85. The inner cavity cross-section of the second turbine conical body 85 gradually decreases from the turbine impact impeller 82 toward the exhaust port 86. In this embodiment, there are four first swirl-reducing ribs 87 and they are evenly distributed around the turbine power output shaft 81. Each first swirl-reducing rib 87 is vertically connected to the side wall of the turbine power output shaft 81. The exhaust port 86 is arranged coaxially with the turbine power output shaft 81. The turbine impact impeller 82 and the second turbine cone body 85 are both located in the cone turbine cavity 74. The turbine power output shaft 81 of the gas-powered cone turbine is clamped to the turbine power input shaft 21 of the driven cone turbine via a shaft protrusion and a clamping groove, and the shaft protrusion and the clamping groove are connected by bolts.

[0062] A third turbine cover plate 83 and a fourth turbine cover plate 84 are provided on either axial side of the turbine impact impeller 82, respectively. The fourth turbine cover plate 84 is located between the turbine impact impeller 82 and the second turbine cone body 85. A second bearing seat 73 is provided on the second conical volute 7. The second bearing seat 73 is provided with a second bearing cavity 732 that communicates with the cone turbine cavity 74. A second bearing 10 that contacts the third turbine cover plate 83 is located within the second bearing cavity 732. A second axial hole 731 that communicates with the second bearing cavity 732 is provided on the second bearing seat 73. The turbine power output shaft 81 passes through the second bearing 10 and the second axial hole 731. A second lubrication cavity 733 is provided on the central sidewall of the second axial hole 731. The second lubrication cavity 733 communicates with the outer wall of the second bearing seat 73 via a second oil injection hole 734. Lubrication can be achieved by injecting lubricating oil into the second oil injection hole 734. The second bearing seat 73 contacts the outer side surface of the third turbine cover plate 83.

[0063] The second conical volute 7 includes a second cone shell 77 that is rotatably engaged with the second turbine cone body 85. A second sealing ring 9 is provided between the inner end surface of the second cone shell 77 and the outer end surface of the second turbine cone body 85. The sealing ring 9 is a polytetrafluoroethylene ring. In this embodiment, two third semicircular annular grooves 76 arranged concentrically and having different diameters are provided on the inner end surface of the second cone shell 77, and two fourth semicircular annular grooves 88 arranged concentrically and having different diameters are provided on the outer end surface of the second turbine cone body 85. A second sealing ring 9 is provided between every two corresponding third semicircular annular grooves 76 and fourth semicircular annular grooves 88, that is, there are two second sealing rings 9 made of polytetrafluoroethylene.

[0064] A decompression gas outlet 72 is located at one end of the conical turbine cavity 74 of the second conical volute 7. The exhaust port 86 of the high-pressure pneumatic conical turbine 8 is located inside this outlet. Four second de-spinning ribs 89 are connected to the inside of the exhaust port 86. Each rib 89 is perpendicular to the inner wall of the outlet 86, and the plane of the ribs 89 is parallel to the turbine power output shaft 81. The pressure relief accelerator tube 71 includes a high-pressure gas nozzle 711 at its output end. The cross-sectional area of ​​the gas passage within the high-pressure gas nozzle 711 gradually decreases along the direction of airflow. The high-pressure gas nozzle 711 is located within the conical turbine cavity 74. The outer edge of the turbine impeller 82 is provided with a clearance notch that matches the high-pressure gas nozzle 711. The second conical volute 7 also has a nozzle hole 75 located on the inner wall of the conical turbine cavity 74. The high-pressure gas nozzle 711 passes through the nozzle hole 75 into the conical turbine cavity 74. The second conical volute 7 includes a third volute and a fourth volute that are interlocked, and the edges of the third volute and the fourth volute are connected by bolts 4.

[0065] When the gas-powered conical pot turbine is working, the high-pressure gas enters the pressure relief acceleration tube 71 through the electric control valve and passes through the high-pressure gas nozzle 711 at a speed of V1. It is compressed and accelerated to V2 and injected into the impact turbine impact impeller 82, driving the high-pressure pneumatic conical pot turbine 8 to rotate. The power gas forms a vortex in the inner cavity of the second turbine conical pot body 85, is decelerated by the first swirl reduction rib 87, and is then decelerated again by the second swirl reduction rib 89 and discharged from the exhaust port 86 of the high-pressure pneumatic conical pot turbine. Since the diameter of the exhaust port 86 is very small, the swirl energy of the air flow it drives is extremely small, so there is no need to set a back-jet structure at the tail end. Then, most of the kinetic energy of the high-pressure gas is converted into mechanical energy of the high-pressure pneumatic conical pot turbine 8 and transmitted to the turbine power input shaft 21 of the pneumatic conical pot turbine 2 of the driven conical pot turbine through the turbine power output shaft 81. The pneumatic conical pot turbine 2 then rotates relative to the first conical volute 1.

[0066] When the driven conical turbine is operating, low-speed air is drawn into the turbine intake vortex 28 at a velocity of V4. It is pressurized and accelerated to V5 by the integrated impeller 26 before entering the conical cavity 25, forming a vortex. This vortex is then flung into the vortex nozzle 16 by the turbine centrifugal impeller 22, forming a pressurized airflow at a velocity of V6. This airflow passes through the compression vortex 15 and the one-way cone valve 141, and is then pumped into the warm and pressurized chamber at a velocity of V7. This entire process effectively involves three stages of pressurization: the turbine intake vortex 28, the integrated impeller 26, and the turbine centrifugal impeller 22. Consequently, the driven conical turbine achieves an energy conversion efficiency of approximately 90%.
