Description

Technical Field

[0002] In modern industrial applications, nanofluid fuels are widely studied and used due to their unique thermophysical properties, especially in improving combustion efficiency and reducing emissions. Nanofluid fuels are usually composed of nanoparticles suspended in traditional fuels, which can significantly improve the heat transfer performance and reaction activity of the fuels; however, although nanofluid fuels have shown many advantages in theoretical and experimental studies, they still face some technical difficulties in practical applications.

[0003] One of the important issues is that nanoparticles are prone to deposition in pipelines that transport nanofluid fuels under high-temperature environments. This deposition phenomenon is mainly because under high-temperature and high-flow rate operating conditions, the interaction between nanoparticles and the interaction with the pipeline wall are enhanced, causing particles to aggregate and eventually deposit on the pipeline wall. This not only reduces the effective fuel flow cross-section in the pipeline, thereby affecting the flow uniformity of the fuel, but may also cause instability in the fuel supply, thereby affecting the stability and efficiency of the entire combustion system.

[0004] In summary, how to avoid the deposition of nanoparticles in pipelines has become an urgent problem that researchers in this field need to solve. Summary of the invention

[0008] Furthermore, the combustion chamber is provided with a ceramic heating element and a temperature sensor, wherein the ceramic heating element is used to heat the nanofluid fuel when starting the combustion process, and the temperature sensor monitors the temperature change during the heating process.

DETAILED DESCRIPTION

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0015] like Figure 1-Figure 6 As shown, the nanofluid fuel stable continuous combustion device of the embodiment of the present invention may include an operating table 20, a combustion chamber 1, a vibration device 4, a nanofluid additive injection valve 5, a storage bin 201 and a pump body 202, wherein the combustion chamber 1 and the storage bin 201 are fixedly connected to the operating table 20, the pump body 202 is installed on the top of the storage bin 201, the pump body 202 is used to extract the nanofluid fuel in the storage bin 201, a fuel pipeline 2, a flexible connecting pipe 6, and a connector 11 are arranged between the pump body 202 and the combustion chamber 1, the vibration device 4 is fixed on the outside of the flexible connecting pipe 6, and the deposited particles on the inner wall of the flexible connecting pipe 6 are caused to fall off by vibration, and the nanofluid additive injection valve 5 is connected to the flexible connecting pipe 6, which is used to add additives during the flow of fuel to reduce deposition.

[0016] It should be noted that a ceramic heating element 9 and a temperature sensor 10 are designed inside the combustion chamber 1 to ensure that the fuel burns in a stable thermal environment. In addition, the structure of the combustion chamber 1 has been optimized in terms of material and layout, and can be corrosion-resistant at high temperatures and maintain a high combustion efficiency. The storage bin 201 is set on the operating table 20 for storing nanofluid fuel. The pump body 202 is installed on the top of the storage bin 201, and the stored fuel can be transported to the combustion chamber 1 through the fuel pipeline 2 and the flexible connecting pipe 6; the function of the pump body 202 is to intermittently (pulse) pass the nanofluid fuel into the combustion chamber 1; the flexible connecting pipe 6 has a certain elasticity in structure, which can absorb part of the vibration and thermal expansion stress to ensure the stability of fuel transportation. The vibration device 4 is fixed to the outside of the flexible connecting pipe 6 to assist the cleaning process. When the vibration device 4 is started, the flexible connecting pipe 6 will generate high-frequency vibration, thereby loosening the particles attached to the inner wall of the pipe, thereby enhancing the effect of automatic cleaning; this vibration-assisted cleaning method can significantly reduce the impact of particle deposition on flow resistance and extend the service life of the equipment. The nanofluid additive injection valve 5 is installed on the fuel pipeline 2 and is responsible for injecting nanofluid additives on demand during the fuel delivery process; the additive can reduce the deposition tendency of nanoparticles, optimize the physical properties of the fuel, and thereby slow down the rate of particle aggregation; this system adapts to different operating conditions by adjusting the proportion of injected additives to ensure that the fuel can still flow stably in a high temperature environment.

[0017] In one embodiment of the present invention, Figure 1 , 2As shown in Figures 5 and 6, the vibration device 4 includes a support frame 41, a driving device 42, a driving rod 43 and a fixed collar 44, wherein the support frame 41 is fixedly connected to the top of the operating table 20, the driving device 42 is installed on one side of the support frame 41, the fixed collar 44 is fixedly sleeved on the outer wall of the flexible connecting tube 6, and a driving rod 43 is arranged between the fixed collar 44 and the output end of the driving device 42, and they are connected through the driving rod 43.

[0018] It should be noted that the driving device 42 described in this embodiment is a cylinder.

[0019] Specifically, in order to avoid deposition in the flexible connecting tube 6, the support frame 41 is fixedly connected to the top of the operating table 20, the driving device 42 is installed on the top of one side of the support frame 41, and the fixed sleeve 44 is fixedly sleeved on the outer wall of the flexible connecting tube 6. A driving rod 43 is provided between the fixed sleeve 44 and the output end of the driving device 42, and they are connected through the driving rod 43. Then, by starting the driving device 42, under the action of the driving rod 43, the fixed sleeve 44 can be driven to shake the flexible connecting tube 6 at a high frequency, thereby effectively avoiding deposition in the flexible connecting tube 6.

[0020] In one embodiment of the present invention, Figure 1-Figure 6 As shown, the pressure pump 7 is installed on the top side of the storage bin 201, and the output end is connected to the fuel pipeline 2, the flow control valve 8 is installed on the fuel pipeline 2, the combustion chamber 1 is provided with a ceramic heating element 9 and a temperature sensor 10, the ceramic heating element 9 is used to heat the nanofluid fuel when starting the combustion process, the temperature sensor 10 monitors the temperature change during the heating process, and a connector 11 is provided between the flexible connecting pipe 6 and the combustion chamber 1. The connector 11 is a sphere (or a cylinder), and a filter is provided at the connection between the connector 11 and the combustion chamber 1. The filter can prevent larger particle sediments from entering the combustion chamber, and the inner wall of the connector 11 is rotatably connected to Rotating rod 111, the outer wall of which is fixedly connected with a scraper 112, the outer wall of which contacts the inner wall of connector 11, and the pulsed fluid enters the interior of connector 11, impacts baffle 112, and rotates under the action of rotating rod 111, synchronously scraping the inner wall of connector 11 to avoid deposition. It should be noted that the pulsed fluid acts on one side of scraper 112 to drive scraper 112 to rotate around rotating rod 111. If the pulsed fluid acts on scrapers 112 on both sides of rotating rod 111, scrapers 112 will not rotate, which puts forward requirements for the connection position between connector 11 and flexible connecting tube 6.

[0021] A filter is provided at the end of the flexible connecting pipe 6, and the disadvantage of directly connecting to the combustion chamber is that larger particle sediments will be deposited on the filter, thereby clogging the end of the flexible connecting pipe 6; and the larger particle sediments are introduced into the connecting head 11, and the cross-sectional area of ​​the connecting head 11 is larger than the cross-sectional area of ​​the flexible connecting pipe 6, so that no blockage will occur in a short time. In addition, larger particle sediments are placed in the connecting head 11, and through the rotation of the scraper, the larger particle sediments will roll and break at the connecting head 11. When the crushed particle size is smaller than the gap of the filter, it can be passed into the combustion chamber 1 for combustion.

[0022] A cooling water pipe 12 is installed on the outer wall of the combustion chamber 1, and an insulating bin 13 is opened in the side wall of the combustion chamber 1. The end of the cooling water pipe 12 is located in the insulating bin 13. An automatic liquid injection pump 14 is installed on the other side of the top of the storage bin 201. The output end of the automatic liquid injection pump 14 is connected to the outer wall of the fuel pipeline 2. The automatic liquid injection pump 14 adjusts the injection amount of the additive according to the fuel flow rate to reduce the formation of sediment and improve the stability of the fuel supply.

[0023] Specifically, the fuel pipeline 2 contains a pressure pump 7 and a flow control valve 8, wherein the pressure pump 7 is installed on the top side of the storage bin 201, and is responsible for extracting fuel from the storage bin 201 and delivering it to the combustion chamber 1 through the fuel pipeline 2. The output end of the pressure pump 7 is directly connected to the fuel pipeline 2, providing the necessary flow pressure for the fuel to ensure a stable delivery process. In addition, the flow control valve 8 is installed on the fuel pipeline 2, and can accurately adjust the flow of the fuel according to system requirements to ensure that the fuel flow rate meets the combustion requirements and improves the combustion efficiency. A ceramic heating element 9 and a temperature sensor 10 are provided inside the combustion chamber 1. The ceramic heating element 9 performs preliminary heating of the nanofluid fuel when starting the combustion process to make the fuel reach an ideal combustion temperature. The temperature sensor 10 monitors the temperature changes during the heating process in real time, and adjusts the power of the heating element through feedback from the temperature control system to ensure that the temperature of the combustion chamber 1 is stable within the range required for combustion to avoid excessively high or low temperatures affecting combustion. In order to improve the combustion effect, in order to prevent larger particles in the fuel from entering the combustion chamber 1 and causing blockage, the fuel pipeline 2 is connected to the combustion chamber 1 through a flexible connecting pipe 6, and a connecting head 11 is arranged between the flexible connecting pipe 6 and the combustion chamber 1. A particle filter is installed at the connection between the connecting head 11 and the combustion chamber 1, which can filter out larger particle deposits in the fuel to avoid blockage of the combustion chamber 1, thereby ensuring smooth flow of fuel in the combustion chamber 1 and maintaining stable combustion. A cooling water pipe 12 is installed on the outer wall of the combustion chamber 1. Under the high-temperature working environment of the combustion chamber 1, the heat generated by the combustion is effectively taken away by the cooling water circulation to prevent the combustion chamber 1 from overheating and affecting the safety and stability of the system. An insulating bin 13 is also arranged in the side wall of the combustion chamber 1, and the end of the cooling water pipe 12 is located in the insulating bin 13. The temperature of the outer wall of the combustion chamber 1 is reduced and heat loss is reduced through water circulation, thereby improving the thermal efficiency of the combustion chamber 1. In order to further optimize the flow characteristics of the fuel and reduce the risk of nanoparticle deposition; An automatic injection pump 14 is installed on the other side of the top of the storage bin 201, and its output end is connected to the outer wall of the fuel pipe 2, which can automatically inject additives into the fuel flow. The automatic injection pump 14 can adjust the injection amount of the additive according to the real-time flow rate of the fuel, so that the fuel is evenly mixed with the additive during the transportation process, effectively reducing the aggregation and deposition of nanoparticles, and improving the fluidity of the fuel and the stability of the supply. This comprehensive design ensures that the fuel maintains continuous flow under high temperature and high flow rate conditions, reduces deposition on the inner wall of the pipeline, extends the service life of the equipment, and improves the overall efficiency and stability of the combustion system.

[0024] It should also be understood that the outer wall of the combustion chamber 1 is also provided with a drainage pipe.
