Description

Technical Field

[0001] This relates to the field of natural gas power generation, specifically to natural gas power generation equipment. Background Technology

[0002] A natural gas power generation unit is a device that converts the heat energy generated by burning natural gas in an internal combustion engine into mechanical energy, which in turn drives a generator to produce electrical energy. To ensure the continuous and stable operation of the generator set, an effective cooling system must be provided to remove the large amount of waste heat generated by the generator and gas engine during operation.

[0003] In underdeveloped regions with weak infrastructure, high temperatures year-round, and frequent dust storms, traditional natural gas power generation plants exhibit numerous environmental incompatibilities.

[0004] In traditional power generation devices, cooling mainly relies on air cooling to create air convection for heat dissipation. The heat dissipation efficiency is highly related to the ambient temperature. In extreme high-temperature environments such as around 40°C, the efficiency of air cooling is low, which can easily lead to generator overheating and subsequent failure. Furthermore, in dusty environments, sand and dust can quickly clog the gaps in the air cooling fins, hindering airflow, further damaging heat dissipation performance, and increasing the difficulty of cleaning and maintenance.

[0005] In addition, the temperature control strategies of traditional devices are often simple and crude, and cannot be adjusted in a precise and dynamic manner according to the actual heat load of the generator. This results in high energy consumption when operating under partial load or variable conditions, and it is difficult to achieve the best balance between efficient heat dissipation and energy-saving operation. Utility Model Content

[0006] To address the issues of equipment adaptability and inefficient temperature control in existing technologies for high-temperature and high-dust environments, this application provides a natural gas power generation unit.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: A natural gas power generation unit includes a casing and a gas turbine and generator housed within the casing. The unit also includes a cooling system. The cooling system comprises water-cooled piping that winds around the surface of the generator casing to form a heat exchange section. An inlet pump and an outlet pump are connected to the two ends of the water-cooled piping, respectively. A detection component is installed on the piping between the heat exchange section and the outlet pump. The detection component includes a housing and a temperature sensor housed within the housing. The cooling system also includes at least one movable louver installed within the casing. A main control unit is also installed within the casing. The inlet pump, outlet pump, and movable louver are electrically connected to the main control unit, and the detection component is signal-connected to the main control unit.

[0008] Furthermore, a humidity sensor is also provided inside the housing of the detection component; the movable louvers include a top louver located on the top wall of the machine body and side louvers located on both sides of the machine body, and an exhaust fan is provided below the top louver, the exhaust fan being electrically connected to the main control unit.

[0009] Furthermore, an inlet pump chamber and an outlet pump chamber are respectively provided on both sides of the machine body.

[0010] Furthermore, the machine body is also hinged to have an openable and closable cover, and the cover is equipped with a locking device; the locking device includes a digital lock and a manual unlocking component, and the digital lock is electrically connected to the main control unit.

[0011] Furthermore, the digital lock is a normally open digital lock that locks when powered on and unlocks when powered off.

[0012] Furthermore, the fuselage has a forward-extending rain shelter.

[0013] Furthermore, a mains power interface is provided at the rear of the machine for the generator wires to pass through and connect to the mains power.

[0014] Beneficial effects: The natural gas power generation unit provided in this application monitors the temperature of the cooling medium, which best reflects the generator's heat load, in real time through a detection component. The signal is transmitted to the main control unit, which precisely controls the speed of the inlet or outlet water pump and the opening and closing of the movable louvers. This achieves dynamic matching between heat dissipation intensity and the actual operating conditions of the generator, upgrading the temperature control mode from coarse open-loop control to fine closed-loop adaptive adjustment, effectively avoiding insufficient heat dissipation or energy waste. At the same time, the unit uses a relatively closed water-cooled pipeline as the core heat dissipation path, preventing sand and dust from entering the equipment through the radiator. The movable louvers remain closed when not necessary, further enhancing the overall sealing and protection of the unit. This allows the unit to achieve efficient heat dissipation while also being adaptable to high-dust environments. Furthermore, the unit has a simple structure, is easy to operate, and is suitable for industrial promotion. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] Example 1: To better understand the specific improvements of this application, this application first provides an introductory description of the specific structure and principle of existing natural gas power generation devices.

[0025] The core logic of natural gas power generation units is that combustion provides energy, drives the mechanical structure to realize energy conversion, and finally forms alternating current. In this process, combustion is the energy source.

[0026] The mainstream technological path for natural gas power generation can be divided into two core modes.

[0027] Firstly, in the mainstream natural gas power generation of large natural gas power plants, after natural gas enters the power plant, it first undergoes purification treatment to remove impurities, ensuring efficient and environmentally friendly combustion. The gas turbine draws in and compresses air through the compressor, increasing the pressure and temperature. When the rated pressure and temperature are reached, the combustion chamber ignites, producing high-temperature and high-pressure gas at about 1200°C. Subsequently, the high-temperature and high-pressure gas drives the turbine blades of the turbine to rotate at high speed. The turbine blades of the turbine are connected to the generator rotor, driving the generator to generate electricity.

[0028] Secondly, there are small and medium-sized natural gas power generation units widely used in underdeveloped areas. The technical principle of small and medium-sized natural gas power generation units is basically the same as that of large natural gas power plants. The difference is that after natural gas and air are mixed in a certain proportion, they enter the cylinder of the gas engine and are ignited by the spark plug, releasing a large amount of heat energy. This causes the gas in the cylinder to heat up and pressurize rapidly. The high temperature and high pressure gas pushes the piston in the cylinder to reciprocate. The piston drives the crankshaft to rotate. The piston and crankshaft are the core driving structures. In essence, they have the same function as turbine blades, only the shape is different. The piston reciprocates, while the impeller rotates. The crankshaft drives the generator rotor to rotate through the transmission mechanism. The rotor magnetic field cuts the stator windings and generates an induced current based on the principle of electromagnetic induction, which ultimately outputs electrical energy.

[0029] The improvements in this application are mainly based on the second type of natural gas power generation device, namely the small and medium-sized natural gas power generation devices widely used in underdeveloped regions. like Figure 1 and Figure 4 , 5 As shown in Figure 6, this figure illustrates the specific structure of the natural gas power generation device of this utility model, including a casing 1 and a gas engine 30 and a generator 20 disposed within the casing 1. The natural gas power generation device also includes a cooling system; the cooling system includes a water-cooled pipe 91, which is wound around the surface of the generator 20 housing to form a heat exchange section 21, with the two ends of the water-cooled pipe 91 connected to an inlet pump 9 and an outlet pump 10, respectively; a detection component 50 is disposed on the pipe between the heat exchange section 21 and the outlet pump 10, the detection component including a housing and a temperature sensor disposed within the housing; the cooling system also includes at least one movable louver disposed on the casing 1; a main control unit 60 is also disposed within the casing 1, the inlet pump 9, the outlet pump 10, and the movable louver are electrically connected to the main control unit 60, and the detection component 50 is signal connected to the main control unit 60.

[0030] The working principle of this technical solution will be explained below in conjunction with its workflow: After the natural gas power generation device of this utility model is started, the gas engine 30 starts to work. Natural gas, whose main component is methane, is mixed with air in a certain proportion and enters the engine cylinder. It is ignited by the spark plug and a combustion reaction occurs, releasing a large amount of heat. This causes the gas in the cylinder to heat up and pressurize rapidly. Then, the high temperature and high pressure gas pushes the piston in the cylinder to reciprocate, which drives the crankshaft to convert thermal energy into mechanical energy. The crankshaft drives the rotor of the generator 20 to rotate through the transmission mechanism. The rotor magnetic field cuts the stator winding, and according to the principle of electromagnetic induction, an induced current is generated in the stator winding, which finally outputs electrical energy.

[0031] During this process, the generator 20 will generate a lot of heat due to electromagnetic losses and copper losses caused by the resistance losses of the generator stator windings, as well as iron losses caused by the hysteresis and eddy current losses of the iron core. This causes the temperature of the generator 20 casing to rise rapidly. In the prior art, the generator is usually cooled by air cooling, which is relatively crude.

[0032] In this application, when the generator 20 is running, the cooling system also starts to operate. The water pump 9 starts to pump the cooling medium from the external or internal water tank into the water cooling pipeline. When the cooling medium flows through the heat exchange section 21 of the water cooling pipeline 91 tightly wrapped around the surface of the generator 20 casing, it exchanges heat with the surface of the generator 20 casing, thereby continuously carrying away the heat generated by the generator 20 and stabilizing the operating temperature of the generator 20 within a safe range.

[0033] In the inventor's on-site construction, based on the extreme environment and realities in some underdeveloped areas, this device is usually set up near rivers and dissipates heat by drawing in river water as a cooling medium.

[0034] It is understandable that in this system, the water-cooled pipe 91 that draws river water actually constitutes a relatively closed heat dissipation structure. This design choice itself has environmental adaptability background reasons. In some underdeveloped areas, infrastructure is backward, sand and dust are prevalent all year round, and industrial support capacity is lacking. The fins of traditional air-cooled radiators or cooling towers are prone to blockage due to the rapid accumulation of sand and dust, which not only leads to the reduction of heat dissipation efficiency, but also brings frequent and difficult maintenance needs. This device can directly use river water as a cooling medium, so that the core heat dissipation process is completed inside the relatively closed pipe, thereby preventing sand and dust from entering the equipment through the heat dissipation path, while ensuring the safety and stability of the electrical system at the structural level.

[0035] In order to achieve accurate monitoring and intelligent control of the operating temperature of generator 20, this device is equipped with a closed-loop control system based on detection component 50 and main control unit 60.

[0036] Specifically, such as Figure 6 As shown by the solid black arrow, the flow path of the cooling medium is indicated. A detection component 50 is installed at the most critical temperature monitoring point: after the water-cooled pipe 91 has completed heat exchange with the generator casing and before the cooling medium leaves the outlet pump 10. The temperature sensor within the detection component 50 monitors the temperature of the cooling medium flowing through this section of the pipe in real time. Specifically, it does not directly detect the cooling medium, but rather the temperature of the pipe itself. Since the water-cooled pipe 91 typically uses copper tubing with excellent thermal conductivity, this temperature directly reflects the real-time thermal load of the generator 20. The temperature sensor continuously transmits the collected temperature signal to the main control unit 60 via a line.

[0037] The main control unit 60 serves as the control center and has multiple preset temperature threshold control logics. It compares and judges the received real-time temperature signal with the preset thresholds and issues control commands to each actuator accordingly.

[0038] The basic working principle is as follows: Generally speaking, the normal operating temperature of the natural gas generator casing is usually between 50°C and 80°C, with the optimal temperature being 60°C-75°C. In the initial stage or when the ambient temperature is not high, the temperature of the cooling medium measured by the detection component 50 is lower than the first threshold. The first threshold can be set to be above 40°C and below 75°C. The main control unit 60 controls the movable louvers to remain closed, and at the same time controls the water pump 9 to run at a lower speed to provide a cooling medium flow rate that meets the basic heat dissipation requirements, thereby reducing the energy consumption of the water pump and achieving energy-saving operation. At this time, the device mainly relies on the circulation of the cooling medium in the water-cooled pipe 91 for heat dissipation. This mode can effectively prevent external sand and dust from entering the interior of the machine body 1. When the load on generator 20 increases or the ambient temperature rises, causing the detected cooling medium temperature to rise and exceed the first threshold, the main control unit 60 will issue a command to drive the movable louvers to open at a certain angle. This will proportionally increase the operating speed of the inlet pump 9 or the outlet pump 10 to increase the circulation flow of the cooling medium in the pipeline, thereby strengthening the cooling intensity of generator 20. The opening of the louvers creates a natural ventilation channel between the inside of the machine and the external environment, introducing external air to achieve auxiliary air cooling of the air flowing through the generator 20 casing and water cooling pipeline 91, thereby enhancing the overall heat dissipation effect.

[0039] Furthermore, from the perspective of pump principles, although a single pump is sufficient to complete the work of water intake and discharge, the reason for designing two pump bodies is that infrastructure in some underdeveloped areas is backward and maintenance is difficult. By creatively adopting a redundant pump design, when one pump fails due to bumps or normal wear, the other pump can still continue to work, preventing the generator 20 from being scrapped due to overheating and buying time for emergency repairs or safe shutdown. This design is based on a deep understanding of specific application scenarios, rather than a simple application of conventional technologies in this field.

[0040] In summary, the working principle of this utility model natural gas power generation device is a complete closed-loop process of monitoring, judgment, and execution. Core temperature parameters are obtained through precisely located temperature monitoring points, and the main control unit 60 intelligently analyzes and makes decisions, and controls subsystems such as water cooling circulation and louver opening and closing in a hierarchical linkage manner, ultimately achieving precise regulation of the operating temperature of the generator 20, ensuring efficient and reliable operation of the power generation device in the high-temperature and high-dust environment of underdeveloped areas.

[0041] It should be clarified that in a typical gas generator set, the gas engine 30 itself is equipped with an independent cooling system. The inventive point of the present application lies in that a dedicated cooling system is additionally designed for the generator 20. These two systems work in coordination to jointly ensure the unit operates at the optimal temperature. The cooling system of the generator 20 and the inherent cooling system of the gas engine 30 are in a cooperative working relationship rather than a substitute relationship.

[0042] Based on the above working principle, the present technical solution achieves the following technical effects: The natural gas power generation device of the present utility model monitors the temperature of the cooling medium in real time through the detection assemblies arranged at key temperature measurement points, and the main control unit 60 makes intelligent decisions according to the temperature threshold, so as to realize precise adjustment of the rotational speed of the water inlet pump 9 or the water outlet pump 10 and linkage control with the opening and closing of the movable louver. This dynamic closed-loop control based on the actual thermal load enables the heat dissipation intensity of the cooling system to be accurately matched with the actual working state of the generator 20. It not only ensures that the generator 20 can maintain a safe working temperature under various loads and extreme high-temperature environments, but also significantly reduces the system energy consumption by automatically reducing the pump rotational speed and closing the movable louver when the thermal load is low, while effectively blocking the intrusion of external sand and dust.

[0043] Embodiment 2: As shown in Figures 1-6 , in order to achieve better technical effects, this embodiment makes further optimized design on the basis of the first embodiment.

[0044] Specifically: The natural gas power generation device provided by the present utility model comprises an integrated machine body 1, which is usually formed by welding steel plates and has sufficient structural strength.

[0045] A rain awning 11 extending horizontally forward is arranged at the front upper part of the machine body 1, which is used for providing rainproof and sunproof protection for the operation area. The internal space of the machine body 1 is reasonably divided into different functional areas. A gas engine 30 and a generator 20 are installed in the core area, wherein the gas engine 30 includes an internal combustion engine fueled by natural gas, and the output shaft of the internal combustion engine is directly connected with the input shaft of the generator 20 through a coupling, so as to convert the mechanical energy generated by the internal combustion engine into electric energy.

[0046] As a key part of the present utility model, the cooling system mainly includes a water cooling pipeline 91, a water inlet pump 9, a water outlet pump 10, a detection assembly 50, a movable louver and a main control unit 60.

[0047] The water-cooled pipe 91 is made of corrosion-resistant metal pipe, such as copper or stainless steel pipe, bent and tightly wound around the surface of the generator 20 housing to form a high-efficiency heat exchange section 21. For ease of maintenance, the two sides of the generator body 1 are respectively provided with independent water inlet pump chamber 31 and water outlet pump chamber 32. The water inlet pump 9 is installed in the water inlet pump chamber 31, and the water inlet end is connected to an external water source through a pipe. A water inlet valve 311 is installed on the connecting pipe. The water outlet pump 10 is installed in the water outlet pump chamber 32, and the water outlet end discharges the heated cooling medium back to the environment. A water outlet valve 321 is installed on the corresponding pipe. The two ends of the water-cooled pipe 91 are respectively connected to the outlet of the water inlet pump 9 and the inlet of the water outlet pump 10, thus forming a complete cooling medium circulation path.

[0048] A detection component 50 is provided on the water-cooled pipeline 91 between the heat exchange section 21 and the water pump 10. The detection component 50 includes a sealed box, and a temperature sensor is provided inside the box. The temperature sensor can be a contact or non-contact type to detect the temperature of the outer wall of the pipeline flowing through it. Preferably, a humidity sensor can also be added inside the box to monitor the ambient humidity of the machine body 1.

[0049] The movable louvers include a top louver 2 installed on the top wall of the body 1 and side louvers 3 installed on the side walls of the body 1. The blade angles of these louvers can be adjusted by actuators such as motors or hydraulic cylinders. As this is prior art, it will not be described in detail here. Below the top louver 2, that is, at the top of the interior of the body 1, an exhaust fan 40 is installed for forced ventilation when needed.

[0050] The core of the control system is the main control unit 60, which is typically a programmable logic controller or a dedicated control circuit board installed in the machine body 1. The inlet pump 9 and outlet pump 10 are electrically connected to the main control unit 60 and receive start / stop and speed control signals. The actuators of the top louvers 2 and the side louvers 3 are electrically connected to the main control unit 60 through the louver control pipe 70.

[0051] The exhaust fan 40 is electrically connected to the main control unit 60 through the exhaust fan control pipe 80, and the temperature sensor and humidity sensor in the detection component 50 are signal connected to the main control unit 60 through the signal transmission pipe 100.

[0052] The machine body 1 is also equipped with safety and protection devices, including a cover hinged to the machine body 1. A locking device is installed on the cover, comprising a digital lock 5 and a mechanical manual unlocking component 4. The digital lock 5 is electrically connected to the main control unit 60 and preferably adopts a normally open design, meaning that the lock tongue extends to lock when power is supplied and retracts to unlock when power is lost. This design is chosen because power supply is unstable in underdeveloped areas. If a normally closed design were used, a sudden power outage could trap maintenance personnel inside the machine body 1, endangering their lives. Simultaneously, the digital lock 5 also serves as the overall start-up function for the equipment.

[0053] The manual unlocking component 4 serves as a backup opening method. It consists of a first lock body 41 and a second lock body 42 with different lock cylinders, and is equipped with two different dedicated keys. During maintenance, two authorized personnel must be present simultaneously, each inserting their respective keys and rotating them synchronously to unlock the machine and open the cover. This design is based on the electrical maintenance safety regulations, which require two people to work together during the maintenance of electrical equipment. This avoids the possibility of unauthorized operation by a single person, ensuring maintenance safety and effectively preventing the risk of single-person theft through key separation management, thereby improving the overall anti-theft capability and operational standardization of the equipment.

[0054] An intake valve 6 and an exhaust valve 7 are respectively provided at the intake and exhaust ports of the gas engine 30 to control the gas supply and exhaust emissions. A mains power interface 8 is provided at the rear of the body 1, through which the power lines generated by the generator 20 pass, which can be used to connect to the local power grid or to supply power to specific equipment.

[0055] The overall workflow of this utility model is as follows: When the device is started, the operator first verifies his / her identity by using the digital lock 5 on the cover to open the device. The natural gas engine inside the gas engine 30 starts, driving the rotor of the generator 20 to rotate and generate electrical energy. The electrical energy is output through the mains power interface 8 at the rear of the unit 1.

[0056] During the power generation process, the generator 20 generates a large amount of heat due to electromagnetic loss. At this time, the cooling system is activated: the water pump 9 draws water from an external water source, and the cooling medium flows through the water-cooled pipes 91 wrapped around the surface of the generator 20 housing, carrying away the heat of the generator through heat exchange.

[0057] The detection component 50, located after the heat exchange section, monitors the temperature of the cooling medium in real time and transmits the signal to the main control unit 60.

[0058] The main control unit 60 intelligently adjusts the entire cooling system based on the received temperature value: when the temperature is low, the louvers are kept closed and heat is dissipated only through water cooling; when the temperature rises, the side louvers 3 are automatically opened and the water pump speed is increased; if the temperature rises further, the top louvers 2 and the exhaust fan 40 below are activated for forced heat dissipation.

[0059] Throughout the entire operation, the device utilizes intelligent closed-loop control involving monitoring, judgment, and execution to ensure that the thermal management of the generator 20 remains in optimal condition. Simultaneously, the sealed design of the casing 1 and the rain shelter 11 provide excellent environmental protection for the equipment. Through the coordinated operation of all systems, this invention achieves stable, efficient, and reliable power generation even in harsh environments.

[0060] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
