Description

Technical Field

[0001] This invention relates to the field of compressor heating and pressurization equipment, and more specifically, to a streamlined compressor heating and pressurization device. Background Technology

[0002] In the design and development of aero engines or gas turbines, compressor testing is a crucial step in evaluating their performance and stability. The primary function of a compressor is to draw in air from the surrounding environment, increase its pressure and temperature, and then deliver it to the combustion chamber or other components. During this process, compressor performance is affected by various factors, one of which is the temperature and pressure of the gas flowing through the compressor inlet.

[0003] Under certain operating conditions, such as high altitudes or high flight speeds, compressors may encounter cryogenic or high-pressure environments, which can lead to performance degradation or instability. Therefore, to simulate these extreme conditions and ensure normal compressor operation, it is typically necessary to heat or pressurize, or simultaneously heat and pressurize, the gas flowing through the compressor inlet during compressor testing. Heating is usually achieved using heaters or burners, while pressurization can be achieved using compressors or expanders.

[0004] Currently, traditional heating and pressurizing devices suffer from significant mixing between high-temperature / high-pressure gases and the flowing gas, resulting in substantial flow losses. Chinese Patent CN 207513638 U invented a heating mechanism for an aero-engine, reducing the bleed air pipes from the engine to the cockpit and solving the signal delay problem caused by the bending and excessive length of the pipes from the engine to the cockpit panel in existing technologies. However, it did not solve the problem of significant mixing between high-temperature / high-pressure gases and the flowing gas. To improve this situation, a heating and pressurizing device is needed that can effectively reduce the mixing intensity of high-temperature / high-pressure gases with the gas flowing through the compressor inlet, thereby effectively reducing flow losses. Summary of the Invention

[0005] This invention provides a streamlined heating and pressurizing device for a compressor, which aims to solve the problem of high mixing intensity between high-temperature / high-pressure gas and the gas flowing through it, effectively reducing the mixing intensity between high-temperature / high-pressure gas and the gas flowing through the compressor inlet, thereby reducing flow loss.

[0006] To achieve the above objectives, the present invention provides a streamlined heating and pressurizing device for a compressor, comprising a compressor inlet channel and a high-temperature / high-pressure gas delivery pipe. The compressor inlet channel is provided with guide vanes, an adjustment assembly, and a flow pipe. The guide vanes are provided with a high-temperature / high-pressure gas inlet. The interior of the guide vanes is hollow, and the surface is provided with ejector holes in the same direction as the airflow direction of the compressor. The high-temperature / high-pressure gas enters the guide vanes through the high-temperature / high-pressure gas inlet and flows out through the ejector holes. The ejector holes control the direction and speed of the outflowing high-temperature / high-pressure gas.

[0007] In one embodiment, the guide vane has a rhomboid columnar structure.

[0008] In one embodiment, the guide vane comprises two rhomboid surfaces and four rectangular surfaces.

[0009] In one embodiment, the ejector holes are disposed on two rectangular curved surfaces of the guide vane.

[0010] In one embodiment, two rectangular curved surfaces with ejector holes are adjacent to each other.

[0011] In one embodiment, the high-temperature / high-pressure gas inlet of the guide vane is located on two rhomboid curved surfaces of the guide vane.

[0012] In one embodiment, the ejector holes of the guide vane are uniformly distributed.

[0013] In one embodiment, the size of the ejector orifice is related to the size of the guide vane and the high-temperature / high-pressure gas flux setting.

[0014] In one embodiment, the compressor inlet channel includes multiple guide vanes and multiple high-temperature / high-pressure gas delivery pipes.

[0015] In one embodiment, the regulating components are located at both ends of the guide vanes to control the intake pressure and exhaust pressure.

[0016] The present invention has the following beneficial effects:

[0017] 1. Reduce mixing intensity: The guide vanes can make the high-temperature / high-pressure gas and the mainstream gas flow in the same direction, which effectively reduces the mixing intensity of the high-temperature / high-pressure gas with the mainstream gas flowing through the compressor inlet, thereby reducing flow loss.

[0018] 2. Simplified device: The device only requires the installation of hollow, porous guide vanes in the compressor inlet channel. The device is simple, allowing operators to easily perform installation, maintenance, and replacement operations, further improving the availability and efficiency of the equipment.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. The described embodiments are some embodiments of this application, but not all embodiments. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] Figure 1 This is a schematic diagram of a streamlined heating and pressurizing device for a compressor according to an embodiment of the present invention. The streamlined heating and pressurizing device includes a compressor inlet channel 100 and a high-temperature / high-pressure gas delivery pipe 300. The compressor inlet channel 100 is characterized by having guide vanes 200, an adjustment assembly, and a flow pipe 600. The guide vanes 200 have a high-temperature / high-pressure gas inlet 220. The guide vanes 200 are hollow inside, and their surfaces have ejector holes 210 that are aligned with the compressor's airflow direction. The high-temperature / high-pressure gas enters the guide vanes 200 through the high-temperature / high-pressure gas inlet 220 and flows out through the ejector holes 210. The ejector holes 210 control the direction and speed of the outflowing high-temperature / high-pressure gas.

[0025] Specifically, the guide vane 200 can change the speed and direction of gas flow, thereby controlling the airflow and making the gas flowing out of the high-temperature / high-pressure gas pipeline 300 have the same velocity as the mainstream gas flow of the compressor.

[0026] Furthermore, the guide vanes 200 can reduce noise, save energy, enhance airflow performance, prevent gas backflow, and mitigate the effects of air pressure oscillations.

[0027] Furthermore, the ejector 210 has multiple functions. First, the ejector 210 can change the direction and velocity of gas flow, allowing it to flow through a specific path. Simultaneously, by controlling the opening and angle, the gas flow velocity can be adjusted, thereby achieving efficient gas delivery and distribution. Second, the ejector 210 can improve the stability of gas flow, reducing instability and eddies, which helps reduce noise and energy loss, improving system performance and efficiency. In addition, the ejector 210 can increase the mixing uniformity of different types of gases, further enhancing system performance and efficiency. Finally, the ejector 210 can also control the gas pressure and flow rate to meet the system's gas supply requirements.

[0028] In one embodiment, such as Figure 2 As shown, the guide vane 200 has a rhomboid columnar structure.

[0029] Furthermore, the guide vane 200 is divided into six surfaces, including two rhomboid curved surfaces and four rectangular curved surfaces.

[0030] Specifically, the guide vane 200 needs to take into account the actual conditions of the pipeline to ensure that it can adapt to the characteristics and requirements of the pipeline. The diamond-shaped curved surface design allows the guide vane 200 to adapt to the pipeline, thereby avoiding excessive turbulence and pressure loss at the bends in the airflow.

[0031] In one embodiment, the ejector hole 210 is disposed on two rectangular curved surfaces of the guide vane 200.

[0032] Specifically, the gas flows into the pipe through the two rectangular curved surfaces of the guide vane 200, so that the gas can be effectively turned and decelerated before entering the pipe. Therefore, the ejector hole 210 needs to be set on the two rectangular curved surfaces of the guide vane 200.

[0033] In one embodiment, two rectangular curved surfaces with ejector holes 210 are adjacent to each other.

[0034] Specifically, the two sides of the guide vane 200 are the main intake side and the main exhaust side, respectively. The two rectangular curved surfaces with ejector holes 210 are located on the main exhaust side of the guide vane 200. The main exhaust side is provided with ejector holes 210, which can make the gas more evenly distributed in the pipe, thereby reducing the flow instability and energy loss caused by uneven gas distribution.

[0035] Furthermore, by flexibly setting the number and position of the ejector holes 210, different process requirements can be met, improving the flexibility and adaptability of the process.

[0036] In one embodiment, the high-temperature / high-pressure gas inlet 220 of the guide vane 200 is disposed on two rhomboid curved surfaces of the guide vane 200.

[0037] In one embodiment, the ejector holes 210 of the guide vane 200 are uniformly distributed.

[0038] Specifically, the uniform arrangement of the ejector holes 210 allows for even gas distribution within the pipeline, preventing uneven gas flow. Furthermore, different types of gases can be mixed more easily, improving the mixing effect.

[0039] In one embodiment, the size of the ejector orifice 210 is related to the size of the guide vane 200 and the high-temperature / high-pressure gas flow rate setting.

[0040] Specifically, the size of the ejector orifice 210 needs to meet the following conditions: It must ensure smooth gas flow; the size of the ejector orifice 210 must be sufficient to allow the heated and pressurized gas to pass through smoothly without blockage or obstruction. It must be adapted to the blade size; the size of the ejector orifice 210 must be appropriate for the blade size. If the blade is large, the ejector orifice 210 needs to be enlarged accordingly to avoid uneven gas flow and energy loss. It must meet the gas flux requirements; the size of the ejector orifice 210 needs to be designed according to the flux requirements of the heated and pressurized gas. If the gas flux is large, the ejector orifice 210 needs to be enlarged accordingly to ensure a sufficient gas supply.

[0041] In one embodiment, the compressor inlet passage 100 includes a plurality of guide vanes 200 and a plurality of high-temperature / high-pressure gas delivery pipes 300.

[0042] Specifically, installing multiple guide vanes 200 inside the pipeline can increase the turbulence of the gas inside the pipeline and improve the gas transport efficiency.

[0043] Furthermore, the number and arrangement of the guide vanes 200 need to be designed according to the specific piping system and process requirements. Generally, the number and arrangement of the guide vanes 200 need to be comprehensively considered based on factors such as the size and shape of the pipeline, gas flow rate, and flow state. In practical applications, flexible adjustments need to be made according to the actual situation to achieve the best results.

[0044] In one embodiment, the adjustment components are disposed at both ends of the guide vane 200 to control the intake pressure and exhaust pressure.

[0045] Specifically, such as Figure 1As shown, the regulating assembly includes a regulating valve system 410 and a regulating valve 420, which are respectively disposed at both ends of the guide vane 200. An orifice plate 500 is disposed on the right side of the regulating valve 420 to control and regulate the pressure and flow rate of the gas.

[0046] Furthermore, the regulating valve system 410 is a control system that can regulate the flow rate and pressure of gas within the compressor to adapt to different operating conditions. The regulating valve 420 is the core component, which can control the gas flow rate by changing the valve opening and the path of gas flow.

[0047] Furthermore, the orifice plate 500 can reduce turbulence and eddies when gas enters the compressor, thereby improving compressor efficiency. The orifice plate 500 also ensures a uniform distribution of gas flow, preventing excessive flow losses within the compressor.

[0048] Specifically, a flow pipe 600 is provided on the left side of the regulating valve system 410. The flow pipe 600, in conjunction with the regulating valve 420, can monitor and control the gas flow rate in real time, ensuring the stable operation of the compressor during the heating and pressurization process. Through the precise measurement of the flow pipe 600, the operator can adjust the gas flow rate as needed to meet the requirements of the process.

[0049] Furthermore, Figure 3 For devices without the guide vanes 200 and the high-temperature / high-pressure gas transmission pipe 300 installed, Figure 1 and Figure 3 compared to, Figure 1 The addition of only guide vanes 200 and high-temperature / high-pressure gas delivery pipes 300 demonstrates the simplicity of the streamlined heating and pressurizing device for the compressor, facilitating installation, maintenance, and replacement by staff.

[0050] The present invention has the following beneficial effects:

[0051] 1. Reduce mixing intensity: The guide vanes can make the high-temperature / high-pressure gas and the mainstream gas flow in the same direction, which effectively reduces the mixing intensity of the high-temperature / high-pressure gas with the mainstream gas flowing through the compressor inlet, thereby reducing flow loss.

[0052] 2. Simplified device: The device only requires the installation of hollow, porous guide vanes in the compressor inlet channel. The device is simple, allowing operators to easily perform installation, maintenance, and replacement operations, further improving the availability and efficiency of the equipment.
