Description

Technical Field

[0001] This utility model relates to the field of combustion device technology, specifically to a liquid fuel gasification device. Background Technology

[0002] In the field of energy utilization and combustion equipment, liquid fuels (such as methanol, ethanol, and biodiesel) are widely used in various heating and combustion equipment, such as industrial boilers, domestic stoves, and catering kitchen equipment, due to their wide availability and relatively low cost. However, traditional liquid fuel combustion methods and related devices have many problems, which seriously limit the efficient utilization of liquid fuels and the improvement of combustion performance.

[0003] First, traditional liquid fuel combustion devices typically inject or drip liquid fuel directly into the combustion zone for combustion. Because liquid fuels evaporate slowly, they are difficult to mix fully with air during combustion, resulting in incomplete combustion. This not only wastes fuel and reduces energy efficiency, but statistics show that in some traditional small catering stoves, the combustion efficiency of liquid fuels may only be 60%-70%, resulting in a significant waste of energy.

[0004] To improve the combustion efficiency of liquid fuels, some devices attempt to gasify them; however, existing gasification methods are often inefficient. Some simple gasification devices mix heated air with liquid fuel, but this method yields poor gasification results and cannot meet the combustion equipment's requirements for gasified fuel. Furthermore, localized overheating or uneven heating can easily occur during gasification, leading to incomplete gasification and affecting combustion quality. In addition, most existing liquid fuel combustion devices do not consider preheating the fuel. The fuel enters the combustion zone at a low temperature, requiring additional energy to raise the temperature, which not only increases energy consumption but also affects combustion stability. In low-temperature environments, traditional devices have slow start-up speeds, requiring a long time to reach normal combustion conditions, reducing the user experience. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of this utility model is to provide a liquid fuel gasification device that can improve the combustion efficiency of liquid fuel and enhance the gasification effect.

[0006] The technical solution adopted by this utility model is: a liquid fuel gasification device, including a combustion furnace head, a gasification pipe and a gasification base. The combustion furnace head is located at the upper end of the gasification base and is connected to a fuel pipe that passes through the gasification pipe. A silicon nitride ceramic heating tube for heating the fuel pipe is provided inside the gasification pipe. A preheating copper pipe is also provided inside the gasification base, which is arranged around the combustion furnace head. One end of the fuel pipe is connected to the preheating copper pipe, and the input end of the preheating copper pipe is provided with a fuel interface.

[0007] In this technical solution, the fuel pipe for supplying fuel to the combustion furnace head is installed inside the gasification pipe. Simultaneously, a silicon nitride ceramic heating element is installed inside the gasification pipe to heat the liquid fuel. The silicon nitride ceramic heating element vaporizes the liquid fuel, and after vaporization, it burns in a gaseous manner, resulting in more complete combustion, greater energy efficiency, and environmental friendliness, effectively improving combustion efficiency. Meanwhile, a preheating copper pipe connected to the fuel pipe is arranged outside the combustion furnace head. During fuel combustion, the preheating copper pipe is heated, achieving the purpose of preheating the fuel. This allows fuel combustion and gasification to be completed simultaneously, significantly further improving the fuel gasification effect and efficiency.

[0008] Preferably, the upper end of the gasification base is recessed to provide a combustion zone for installing the combustion furnace head, the bottom of the side wall of the gasification base corresponding to the combustion zone is provided with an embedding groove for embedding a preheating copper tube, and the outer side of the gasification base is provided with an installation notch for leading out the end of the preheating copper tube.

[0009] Preferably, the combustion zone has an installation port in the middle for the upper end of the combustion furnace head to pass through, and the combustion zone also has water-blocking protrusions arranged around the installation port.

[0010] Preferably, the outer periphery of the gasification pipe is provided with an installation part that connects to the combustion furnace head, and the installation part is also provided with a circumferentially arranged receiving part for accommodating the silicon nitride ceramic heating tube at the bottom of the combustion furnace head.

[0011] Preferably, one end of the gasification pipe is provided with an outlet for the fuel pipe and the silicon nitride ceramic heating pipe to pass through, and a fixing cap is installed on the outlet.

[0012] The beneficial effects of this invention are as follows: This invention utilizes the high thermal conductivity and high-temperature resistance of silicon nitride ceramics to uniformly heat the liquid fuel within the fuel tube, enabling the liquid fuel to complete the gasification process in a short time, significantly improving the gasification rate. The fuel tube is inserted inside the gasification tube, ensuring that the liquid fuel is rapidly converted into gas under a constant high-temperature environment, avoiding incomplete gasification caused by local overheating or uneven temperature. The preheating copper tube surrounding the combustion head uses the heat generated by combustion to preheat the liquid fuel, increasing the initial temperature of the fuel entering the gasification tube and reducing the energy consumption of the silicon nitride ceramic heating element. This invention systematically solves the core pain points of traditional liquid fuel combustion devices, achieving breakthrough improvements in key indicators such as combustion efficiency, energy saving and environmental protection, start-up speed, and volumetric energy consumption. It has significant technological advancements and industrial application value, and is particularly suitable for modern combustion equipment fields with stringent energy efficiency and environmental protection requirements.

Detailed Implementation

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0018] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0019] like Figure 1 and Figure 2 As shown in the figure, a specific embodiment of this utility model provides a liquid fuel gasification device, including a combustion burner 300, a gasification pipe 200, and a gasification base 100. The combustion burner 300 is located at the upper end of the gasification base 100 and is connected to a fuel pipe 400 that passes through the gasification pipe 200. A silicon nitride ceramic heating tube 500 for heating the fuel pipe 400 is provided inside the gasification pipe 200. A preheating copper pipe 600 is also provided inside the gasification base 100, which is arranged around the combustion burner 300. One end of the fuel pipe 400 is connected to the preheating copper pipe 600, and the input end of the preheating copper pipe 600 is provided with a fuel interface.

[0020] like Figure 1 and Figure 2As shown, with the above configuration, in this embodiment, the fuel pipe 400 for supplying fuel to the combustion burner head 300 is inserted into the gasification pipe 200. The gasification pipe 200 is also equipped with a silicon nitride ceramic heating tube 500 for heating the liquid fuel. The silicon nitride ceramic heating tube 500 can gasify the liquid fuel. After gasification, the fuel is burned in a gaseous manner, making the combustion of the fuel more complete, and also more energy-saving and environmentally friendly, effectively improving the combustion efficiency. By utilizing the high thermal conductivity (thermal conductivity up to 80 W / (m·K)) and high temperature resistance (withstanding temperatures up to 1300℃) of silicon nitride ceramics, the liquid fuel in the fuel tube 400 is uniformly heated, enabling the liquid fuel to complete the vaporization process in a short time (≤5 seconds). The vaporization rate is increased by more than 40% compared to the traditional resistance wire heating method. Furthermore, the fuel tube 400 is inserted inside the vaporization tube 200 to form a sealed heating chamber, reducing heat loss (thermal efficiency of over 92%). This ensures that the liquid fuel is rapidly converted into gas under a constant high temperature environment, avoiding incomplete vaporization caused by local overheating or uneven temperature.

[0021] Meanwhile, the preheating copper tube 600 surrounding the combustion furnace head 300 uses the waste heat generated by combustion to preheat the fuel, thereby increasing the initial temperature of the fuel entering the gasification tube 200 and reducing the energy consumption of the silicon nitride ceramic heating tube 500, thus achieving an energy closed loop of "reusing combustion waste heat". This structure allows the preheating copper tube 600 to preheat the fuel simultaneously when the combustion furnace head 300 is working, so that the fuel reaches the gasification threshold more quickly after entering the gasification tube 200. The time from device start-up to stable combustion is greatly shortened, making it especially suitable for rapid start-up in low-temperature environments and improving the ease of use of the equipment.

[0022] like Figure 1 and Figure 2 As shown, in order to install the combustion burner head 300 and improve the preheating effect of the fuel, this embodiment has a combustion zone 110 for installing the combustion burner head 300 recessed at the upper end of the gasification base 100. The bottom of the side wall of the gasification base 100 corresponding to the combustion zone 110 is provided with an embedding groove for embedding the preheating copper tube 600. The outer side of the gasification base 100 is provided with an installation notch 120 for the end of the preheating copper tube 600 to be led out. In this way, the preheating copper tube 600 can be embedded in the embedding groove and led out from the installation notch 120. One end of the preheating copper tube 600 can be provided with a fuel interface for connecting to a fuel supply device. The combustion burner head 300 can heat the preheating copper tube 600 simultaneously during the combustion process.

[0023] like Figure 1 and Figure 2 As shown, in this embodiment, an installation port for the upper end of the combustion head 300 to pass through is provided in the middle of the combustion zone 110, and a water-blocking protrusion 130 is also provided in the combustion zone 110 surrounding the installation port. The water-blocking protrusion 130 can play a waterproof role to prevent the combustion device from being extinguished due to water ingress during use.

[0024] As mentioned above, the combustion burner head 300 needs to be connected to the fuel pipe 400 located inside the gasification pipe 200. In practical applications, the lower end of the combustion burner head 300 needs to be installed on the outer periphery of the gasification pipe 200. In this embodiment, an installation part 210 for connecting to the combustion burner head 300 is provided on the outer periphery of the gasification pipe 200, which can be installed by means of threaded connection. In addition, the installation part 210 is also provided with a circumferentially arranged receiving part for accommodating the silicon nitride ceramic heating tube 500 at the bottom of the combustion burner head 300. In this way, the silicon nitride ceramic heating tube 500 can extend to the bottom area of ​​the combustion burner head 300, which can fully heat the liquid fuel and improve the gasification effect.

[0025] like Figure 1 and Figure 2 As shown, in order to accommodate the fuel supply pipe 400 and the silicon nitride ceramic heating element 500 installed inside the vaporization pipe 200, this embodiment provides an outlet end for the fuel supply pipe 400 and the silicon nitride ceramic heating element 500 at one end of the vaporization pipe 200, and a fixing cap 220 is installed at the outlet end. In this way, the fuel supply pipe 400 and the silicon nitride ceramic heating element 500 can be fixed by the fixing cap 220 after being led out.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
