Description

Technical Field

[0001] This utility model relates to the field of gas turbine equipment technology, and in particular to a gas turbine multi-parameter synchronous acquisition device. Background Technology

[0002] As a power source, gas turbines play a crucial role in power generation, industrial drives, and aerospace. To ensure their long-term safe, stable, and efficient operation, it is essential to monitor key performance parameters such as temperature, pressure, and vibration in real time. In existing technologies, various sensors are installed in key components of the gas turbine, such as the compressor and combustion chamber, to collect operational data. However, the signal acquisition and processing systems of these sensors are often independent, with data collected from different channels, lacking an integrated platform to process this information synchronously.

[0003] This decentralized monitoring method makes it difficult to achieve strict synchronization of the collection of different parameters in time. This creates an obstacle to analyzing the complex coupling relationship between parameters under rapidly changing operating conditions, thereby affecting the accurate assessment of equipment operating status and the prediction of early faults. At the same time, multiple independent monitoring systems also make the data integration process cumbersome and reduce the response efficiency of fault diagnosis and operation strategy optimization.

[0004] Therefore, this utility model proposes a multi-parameter synchronous acquisition device for gas turbines to address the shortcomings of existing technologies. Summary of the Invention

[0005] In view of the problems in the existing gas turbine multi-parameter synchronous acquisition devices, such as scattered parameter monitoring points, difficulty in synchronizing data acquisition, and lack of centralized processing methods, which affect the accurate assessment of equipment operating status, this utility model aims to provide a gas turbine multi-parameter synchronous acquisition device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a multi-parameter synchronous acquisition device for a gas turbine, including a compressor, and a combustion chamber and a gas turbine connected in sequence to the compressor outlet; the device also includes a detection and control mechanism.

[0007] The detection and control mechanism consists of a detector and multiple sensors. The sensors are fixedly installed on the outer walls of the compressor and combustion chamber to collect real-time operating data of the equipment at different key locations.

[0008] Furthermore, the detector connects to the sensor via the connection inlet and connection outlet on its housing. This structure, which combines distributed sensors with a centralized detector, forms an integrated external monitoring system, enabling convenient synchronous acquisition and processing of multiple parameters of the gas turbine.

[0009] Preferably, the gas turbine has a central column coaxially arranged inside, which serves as the main rotating shaft for transmitting torque. Multiple circumferentially distributed blades are fixedly connected to its outer circumference by welding or tenoning. The blades and the central column together constitute a work rotor structure that converts the thermal energy of the gas into mechanical energy.

[0010] Preferably, the device further includes a storage tank disposed on one side of the combustion chamber. The storage tank is connected to the fuel inlet of the combustion chamber through a fuel inlet pipe, serving as a fuel supply source to provide a stable and continuous fuel supply to the combustion chamber.

[0011] Furthermore, in order to achieve precise control of fuel supply, a discharge pipe is connected in series with the fuel inlet pipe. Through the valve or flow meter integrated inside the discharge pipe, the fuel flow rate entering the combustion chamber can be actively adjusted according to the real-time operating conditions of the device, thereby optimizing the combustion process and improving the working quality.

[0012] Preferably, the outlet of the gas turbine is connected to an exhaust box, and an exhaust pipe is connected to the exhaust box to smoothly discharge most of the high-temperature exhaust gas after power is done, thereby completing the main power cycle.

[0013] Furthermore, in order to achieve cascaded energy utilization, a recovery pipe is also connected to the exhaust box. The function of the recovery pipe is to divert a portion of the exhaust gas that still has a relatively high temperature from the main exhaust flow.

[0014] As an energy-saving implementation method, the device also includes a waste heat recovery unit. The aforementioned recovery pipe is connected to the inlet of the waste heat recovery unit through a connecting pipe, and the diverted high-temperature waste gas is introduced into the waste heat recovery unit for heat exchange, thereby recovering the heat energy in this part of the waste gas and improving the overall energy utilization rate of the system.

[0015] Preferably, the detector housing integrates a connection inlet and a connection outlet, and the sensor is electrically connected to the connection inlet and the connection outlet respectively via wires. This hard-wired connection method forms a stable and reliable physical signal transmission link, ensuring the integrity, accuracy and real-time performance of data from the acquisition end to the processing end.

[0016] This utility model has the following beneficial effects: 1. This utility model, through a detection and control mechanism installed outside the compressor and combustion chamber, including a detector connected to external sensor signals, solves the problem in the prior art of scattered monitoring points for key parameters of gas turbines and difficulty in synchronous data collection and centralized processing, achieving the technical effect of convenient, comprehensive and synchronous monitoring of equipment operating status.

[0017] 2. This utility model solves the problem of low fuel supply control precision in the prior art by setting up a storage tank, fuel inlet pipe and discharge pipe connected to the combustion chamber, and achieves the technical effect of accurately controlling the amount of fuel, improving combustion efficiency and working quality.

[0018] 3. This utility model solves the problem of energy waste in high-temperature exhaust gas discharged from gas turbines in the prior art by setting up a recovery pipe and waste heat recovery device connected to the exhaust gas box, and achieves the technical effect of recovering and utilizing part of the exhaust gas heat energy and improving the overall energy efficiency of the device.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0022] Please refer to Figures 1 to 4This utility model provides a multi-parameter synchronous acquisition device for a gas turbine, including a compressor 1, and a combustion chamber 3 and a gas turbine 4 connected sequentially to the outlet of the compressor 1. The compressor 1, combustion chamber 3, and gas turbine 4 together constitute a power frame for converting fuel chemical energy into mechanical energy. The device further includes a detection and control mechanism 2, which is located outside the compressor 1 and combustion chamber 3, and is used to comprehensively and synchronously detect and control various parameters during the operation of the entire device. Specifically, refer to... Figure 1 , Figure 2 and Figure 4 The detection and control mechanism 2 includes a detector 201 and a sensor 204. The sensor 204 is fixedly installed on the outer wall of the compressor 1 and the combustion chamber 3 to collect operating data at key locations in real time. The detector 201 is used to centrally receive and process the data from the sensor 204. In order to build a reliable data transmission path, the detector 201 connects to the sensor 204 through the connection inlet 202 and connection outlet 203 provided on its housing, realizing convenient and synchronous acquisition of multiple parameters of the gas turbine.

[0023] Please refer to Figure 1 , Figure 2 and Figure 4 The sensor 204 of the detection and control mechanism 2 is fixedly installed on the outer wall surface of the compressor 1 and the combustion chamber 3. Its specific location can be selected according to the type of parameter to be monitored. For example, it can be arranged in the inlet and outlet areas of the compressor 1 to monitor the intake and exhaust pressure and temperature, or arranged on the wall of the combustion chamber 3 to monitor its surface temperature. The sensor 204 is electrically connected to the connection inlet 202 and the connection port 203 respectively through wires, and transmits the collected analog or digital signals to the detector 201. The detector 201 has a built-in data processing unit and display interface. The connection inlet 202 and the connection port 203 are integrated on its housing to receive signals from the sensor 204. The function of the detector 201 is to synchronously process all data and centrally display or store it, providing operators with a comprehensive view of the equipment status, ensuring that multi-point, multi-parameter synchronous and accurate monitoring can be easily achieved in the complex gas turbine environment.

[0024] For the energy conversion structure inside the gas turbine 4, please refer to... Figure 2 The gas turbine 4 has a central column 11 coaxially arranged inside. The central column 11 serves as the main rotating shaft. Multiple blades 10 are fixedly connected to its outer circumference by welding or tenoning. When the high-temperature and high-pressure gas impacts the blades 10, it drives the blades 10 and the central column 11 to rotate at high speed as a whole, thereby outputting mechanical work.

[0025] As a preferred embodiment, in order to achieve precise control and stable supply of fuel to combustion chamber 3, please refer to... Figure 1 and Figure 3 A storage tank 207 is provided on one side of the combustion chamber 3. The storage tank 207 is connected to the fuel inlet of the combustion chamber 3 through the fuel inlet pipe 205 and is used to store and transport fuel. Furthermore, in order to regulate the fuel flow rate into the combustion chamber 3, a discharge pipe 206 is connected in series on the fuel inlet pipe 205. The discharge pipe 206 can integrate a valve or flow meter. Through the structure, the fuel supply can be precisely controlled according to the working conditions, thereby improving combustion efficiency and working quality.

[0026] As another preferred embodiment, in order to effectively treat and recover energy from the high-temperature exhaust gas discharged from the gas turbine 4, please refer to... Figure 1 The outlet end of the gas turbine 4 is connected to the exhaust box 5 via a flange. The exhaust box 5 is fixedly connected to the exhaust pipe 6 for discharging most of the exhaust gas. At the same time, in order to utilize the waste heat in the exhaust gas, a recovery pipe 7 is also fixedly connected to the side wall of the exhaust box 5. The recovery pipe 7 leads out a portion of the high-temperature exhaust gas and connects to the inlet of the waste heat recovery unit 9 via a connecting pipe 8. The waste heat recovery unit 9 performs heat exchange on this portion of high-temperature exhaust gas, thereby recovering heat energy, improving the energy utilization efficiency of the entire device and shortening the working time.

[0027] Working principle: When the device is working, the compressor 1 draws in and compresses air, and sends the high-pressure air into the combustion chamber 3; at the same time, the fuel stored in the storage tank 207 enters the combustion chamber 3 through the discharge pipe 206 and the fuel inlet pipe 205 with precision control and mixes with the high-pressure air to produce high-temperature and high-pressure gas; the high-temperature and high-pressure gas then enters the gas turbine 4, impacts and drives the impeller 10, and drives the central column 11 to rotate at high speed to output mechanical work.

[0028] Throughout the entire operation, multiple sensors 204, fixedly installed outside the compressor 1 and combustion chamber 3, collect key operating parameters such as temperature and pressure on their surfaces in real time. These parameter signals are then synchronously transmitted to the detector 201 via the connection inlet 202 and the connection outlet 203. The detector 201 centrally processes, analyzes, and displays the received multiple signals. Through this collaborative working method of the detection and control mechanism 2, the synchronous and convenient acquisition and monitoring of multiple key position parameters of the device are realized, effectively solving the problem of scattered monitoring points and difficulty in timely and synchronous data acquisition in the existing technology.

[0029] The high-temperature exhaust gas from the gas turbine 4 enters the exhaust box 5. Part of the exhaust gas is discharged directly through the exhaust pipe 6, while the other part is guided to the recovery pipe 7 and then enters the waste heat recovery unit 9 through the connecting pipe 8 for heat recovery, thereby improving the overall energy utilization efficiency of the device.
