Description

Technical Field

[0001] This invention relates to the field of fuel distribution equipment technology, specifically to a gate-type vaporized alcohol-based fuel distribution equipment. Background Technology

[0002] Most industrial furnaces and kilns still rely on diesel, liquefied petroleum gas, or natural gas as their primary fuels, resulting in high costs and severe pollution. In contrast, alcohol-based fuels are more economical and environmentally friendly.

[0003] However, most industrial furnaces and kilns burn alcohol-based fuels through atomization. Atomization limits the dispersion of the fuel, and the combustion process involves endothermic vaporization. Therefore, directly burning alcohol-based fuels via atomization results in incomplete combustion, leading to waste. Furthermore, the combustion process produces emissions of acids, alcohols, and aldehydes, which are corrosive and toxic, posing environmental hazards. Therefore, designing a system that can vaporize alcohol-based fuels to ensure complete combustion is essential. A gantry-type vaporized alcohol-based fuel generation and distribution system can achieve one-stop generation of vaporized alcohol-based fuel and deliver it to multiple ports for combustion as needed. Existing fuel distribution devices still have some shortcomings in vaporizing alcohol-based fuels.

[0004] For example, CN104613510A discloses an alcohol-based fuel supply device. The control component controls the on / off connection and maintenance of the fuel tank to the stove, making it convenient to use and maintain. Users can easily operate it without professional knowledge. The pipeline and return pipeline are three-layered pipes consisting of an inner anti-corrosion layer, an anti-static layer, and a protective layer. The fuel tank, maintenance valve, booster pump, tee, start valve, and stove are connected sequentially through the pipeline, enhancing safety. The fuel tank no longer needs to be mounted high, making installation easier and more suitable for widespread use. While the above device improves safety during use, it cannot adaptively adjust the throttling effect of the throttling valve according to the amount of fuel fed in during the vaporization of alcohol-based fuel. It lacks the function of efficiently vaporizing fuel. The valves at the feed position of existing distribution devices have a single function; allowing too much fuel to enter at once will affect vaporization efficiency. Furthermore, existing fuel distribution devices cannot adjust the burner arrangement according to the needs of the heat-using equipment, resulting in low adjustability. Furthermore, the existing fuel distribution system directly uses methanol as fuel, resulting in incomplete combustion that produces formic acid that severely corrodes metal equipment, formaldehyde that pollutes the air and affects on-site workers, and unburned methanol that wastes energy and pollutes the air. Additionally, using methanol as fuel in industrial, district heating, and residential heating systems results in low combustion rates, low power release, uneven heating of heat storage devices, and low thermal radiation. Summary of the Invention

[0005] This invention proposes a gate-type vaporized alcohol-based fuel distribution device, which solves the problems of existing fuel distribution devices that directly distribute methanol as fuel, resulting in incomplete combustion and the formation of formic acid that severely corrodes metal equipment, cannot adaptively adjust the throttling effect of the feed inlet according to the amount of liquid fuel remaining, and have insufficient vaporization effect.

[0009] As a preferred embodiment of the present invention, a cover plate is fixedly connected to the surface of the fan, and a notch is provided on the surface of the cover plate, and the end of the connecting pipe is connected to the cover plate.

[0010] As a preferred embodiment of the present invention, a connecting cover is fixedly connected to the right side of the burner, and a heat insulation plate is provided on the outer side of the connecting cover. The heat insulation plate is made of aerogel material.

[0011] As a preferred embodiment of the present invention, the cross groove and the extension groove are interconnected, the extension groove is symmetrically distributed on the left and right sides of the cross groove, and the connecting strip is connected end to end inside the cross groove and the extension groove.

[0012] As a preferred embodiment of the present invention, the outer wall of the connecting strip is in contact with the inner wall of the groove, and the high-temperature resistant rubber support plate is symmetrically distributed on the left and right sides of the cross groove and the extension groove.

[0013] As a preferred embodiment of the present invention, the throttling component includes a fixed plate fixedly installed inside the housing, columns slidably installed around the fixed plate, a memory alloy spring sleeved on the outer side of the upper half of the column, the two ends of the memory alloy spring being connected to the column and the fixed plate respectively, a sliding plate fixedly connected to the bottom end of the column, a fluid channel fixedly provided on the surface of the sliding plate, and a connecting groove opened on the surface of the fixed plate.

[0015] As a preferred embodiment of the present invention, the vaporization bed includes a retention plate fixedly installed inside the connecting shell, an electric heating tube is provided between the retention plate and the adjacent retention plate, the electric heating tube is fixedly connected to the connecting shell, a through hole is opened on the retention plate in the middle position for the support rod to pass through, and a connecting block is fixedly connected between two adjacent retention plates.

[0016] As a preferred embodiment of the present invention, the retention disk is spherical, and four layers of retention disks are evenly distributed inside the connecting shell, with the retention disks of adjacent layers interleaved.

[0017] The working principle and beneficial effects of this invention are as follows:

[0018] 1. The alcohol-based fuel artificial gas is generated by a central station equipment with functions of detection, metering, pressure regulation, heat tracing and distribution. It is then transmitted to multiple burners for combustion. This solves the problems of low thermal efficiency, incomplete combustion and the production of harmful substances such as formic acid, formaldehyde and methanol after combustion of methanol as fuel. It will not pollute the air or affect on-site workers during use, and will not produce unburned methanol that wastes energy.

[0019] 2. Through the established vaporization bed, the device can evenly spread the fuel injected into the outer shell onto the surface of each retention plate. Utilizing four sets of retention plates arranged in an alternating pattern, in conjunction with electric heating tubes, the device can efficiently vaporize the fuel in the retention plates, improving the device's vaporization efficiency and solving the problem of low vaporization efficiency in existing fuel distribution devices. It also solves the problems of low combustion rate and low power release of methanol as fuel in industrial, district heating, and residential cooking and heating equipment; and solves the problems of uneven heating and low thermal radiation in heat storage devices. The gate-type alcohol-based fuel vaporizer is the first to prepare liquid alcohol-based fuel into artificial gas; and it enables one main unit to support multiple burners, making it suitable for kiln equipment with multiple fire points.

[0020] 3. By using a fixed plate and a sliding plate, along with a memory alloy spring and a float, the device can adaptively adjust the distance between the fixed plate and the sliding plate according to the liquid level during operation. This causes the fluid channel to protrude from the upper surface of the fixed plate. At this time, the feed pipe can be used as a throttling valve. The more liquid in the device, the higher the sliding plate becomes, resulting in a larger protruding part of the fluid channel and a more obvious throttling effect. This achieves the function of adaptively changing the throttling effect of the throttling valve according to the amount of feed, thus improving the functionality of the device.

[0021] 4. The cross groove and extension groove allow the burner to be supported by a high-temperature resistant rubber support plate during operation. By placing the burner in different positions within the cross groove and extension groove, the burner arrangement can be adjusted to adapt to different heat-using equipment, thus improving the adjustability of the device. This solves the problem that existing fuel distribution devices cannot adjust the burner arrangement according to the needs of heat-using equipment, giving the device a greater advantage in adaptability.

[0022] 5. Through the connecting pipe, the device can reintroduce the gas discharged from the pressure relief valve into the air inlet of the blower, thereby enabling the reuse of vaporized alcohol-based fuel and giving the device a fuel recovery function. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figures 1-14 As shown, a gate-type vaporized alcohol-based fuel distribution device includes a shell 1. A connecting shell 2 is installed on the outer side of the lower half of the shell 1. A vaporization bed 21 is arranged inside the connecting shell 2. The vaporization bed 21 can efficiently vaporize liquid fuel and use vaporized alcohol-based fuel for distribution, which solves the defects of low thermal efficiency and incomplete combustion of methanol as fuel, while avoiding air pollution and affecting the working environment. A feed pipe 3 is connected to the left side of the connecting shell 2. A fan 4 is installed on the left side of the upper half of the shell 1. A thermometer 5 is installed on the upper left side of the shell 1 for real-time monitoring. The temperature inside the outer casing 1 is measured. A pressure gauge 6 is installed on the upper right side of the outer casing 1 to monitor the air pressure inside the device. A pressure relief valve 7 is installed on the top of the outer casing 1. The pressure relief valve 7 can automatically release pressure when the air pressure is too high to ensure safety during use. A sealing cover 8 is provided on the outside of the pressure relief valve 7. A connecting pipe 11 is fixedly connected to the top of the sealing cover 8. The connecting pipe 11 facilitates the subsequent recovery and reuse of the gas discharged from the pressure relief valve 7. An air inlet pipe 9 is connected to the right side of the outer casing 1. A burner 10 is connected to the right side of the air inlet pipe 9. A support plate is installed on the outside of the burner 10. 13. A cross groove 14 is provided in the middle of the support plate 13, and extension grooves 15 are provided on the left and right sides of the lower half of the support plate 13. The cross groove 14 and extension grooves 15 on the support plate 13 facilitate subsequent adjustment and fixation of the burner 10, improving the adjustability of the device. Connecting strips 16 are fixedly connected to the inner walls of the cross groove 14 and extension grooves 15. A groove 17 is provided on the surface of the burner 10. The connecting strips 16 can be used in conjunction with the grooves 17, so that the device can stably support the burner 10 and improve the overall stability of the device. Qualitatively, a high-temperature resistant rubber support plate 18 is fixedly installed on the surface of the support plate 13, and a throttling component 19 is installed inside the feed pipe 3. A folding rod 25 is provided on the right side of the throttling component 19, and a support rod 24 is fixedly connected to the bottom of the folding rod 25. A float 23 is fixedly connected to the bottom of the support rod 24, and a fixed cylinder 22 is attached to the outside of the float 23. The folding rod 25 can drive the lower half of the throttling component 19 to rise and fall when the height of the float 23 is raised, so that the device can automatically increase the throttling effect when the liquid storage is too large, thus improving the functionality of the device.

[0042] Example 2

[0043] like Figures 1-14As shown, based on the same concept as in Embodiment 1 above, this embodiment also proposes a gate-type vaporized alcohol-based fuel distribution device.

[0044] In this example, the bottom of the outer shell 1 is a recessed structure, the fixed cylinder 22 and the outer shell 1 are fixedly connected, the inner wall of the fixed cylinder 22 is in contact with the outer wall of the float 23, the support rod 24 and the folding rod 25 form a lifting structure between the float 23 and the outer shell 1, and a mesh plate 26 is fixedly installed inside the outer shell 1. Through the lifting structure on the device, the float 23 can rise and fall with the liquid level, so as to adjust the throttling effect of the feed position in the future.

[0045] In this example, a cover plate 27 is fixedly connected to the surface of the fan 4. A notch 28 is provided on the surface of the cover plate 27. The end of the connecting pipe 11 is connected to the cover plate 27. Through the notch 28 on the device, when the connecting pipe 11 is connected to the cover plate 27, the notch 28 can realize the air intake function, which can not only ensure the ventilation effect, but also recover the gas generated during depressurization.

[0046] In this example, a connecting cover 12 is fixedly connected to the right side of the burner 10. A heat insulation plate 20 is provided on the outside of the connecting cover 12. The heat insulation plate 20 is made of aerogel material. The connecting cover 12 can shield the outside of the burner 10. The heat insulation plate 20, together with the connecting cover 12, enables the device to achieve a heat insulation effect, preventing the high-temperature airflow from the furnace opening from overflowing, so as to ensure safety during use.

[0047] In this example, the cross groove 14 and the extension groove 15 are interconnected. The extension groove 15 is symmetrically distributed on the left and right sides of the cross groove 14. The connecting strip 16 is connected end to end inside the cross groove 14 and the extension groove 15. The connecting strip 16 facilitates the subsequent adjustment of the injection position of the vaporized alcohol-based fuel according to the position of the heat-using equipment, thereby improving the adjustability of the device.

[0048] In this example, the outer wall of the connecting strip 16 and the inner wall of the groove 17 are in contact with each other. The high-temperature resistant rubber support plate 18 is symmetrically distributed on the left and right sides of the cross groove 14 and the extension groove 15. The high-temperature resistant rubber support plate 18 can realize the support function, which makes it convenient to adjust the fuel distribution position according to the position of the heat-using equipment, thus improving the convenience of the device during use.

[0049] In this example, the throttling component 19 includes a fixed plate 1901 fixedly installed inside the housing 1. Columns 1905 are slidably installed around the fixed plate 1901. A shape memory alloy spring 1906 is sleeved on the outer side of the upper half of the column 1905. The two ends of the shape memory alloy spring 1906 are connected to the column 1905 and the fixed plate 1901 respectively. A sliding plate 1902 is fixedly connected to the bottom end of the column 1905. A fluid channel 1904 is fixedly provided on the surface of the sliding plate 1902. A connecting groove 1903 is opened on the surface of the fixed plate 1901. When the temperature of the device is too high, the shape memory alloy spring 1906 automatically contracts, thereby pulling the sliding plate 1902 below to move upward, causing the fluid channel 1904 to move upward. At this time, the fluid channel 1904 protrudes from the surface of the fixed plate 1901. The throttling function is achieved by utilizing the backflow structure on the fluid channel 1904, improving the performance of the device.

[0050] In this example, the height of the fluid channel 1904 is greater than the depth of the connecting groove 1903. The inner wall of the connecting groove 1903 is in contact with the outer wall of the fluid channel 1904. The slide plate 1902 and the folding rod 25 form a telescopic structure with the fixed plate 1901 through the float 23 and the support rod 24. The device can also use the change in liquid level to make the float 23 move up and down automatically, thereby making the slide plate 1902 and the folding rod 25 move up and down, so as to adjust the throttling effect of the device in the future and improve the practicality of the device.

[0051] In this example, the vaporization bed 21 includes a retention plate 2102 fixedly installed inside the connecting shell 2. An electric heating tube 2101 is provided between the retention plate 2102 and the adjacent retention plate 2102. The electric heating tube 2101 is fixedly connected to the connecting shell 2. A through hole 2103 is opened on the retention plate 2102 in the middle position for the support rod 24 to pass through. A connecting block 2104 is fixedly connected between two adjacent retention plates 2102. The liquid alcohol fuel is collected through the retention plate 2102 on the device, so that the device can more efficiently vaporize the liquid fuel in multiple retention plates 2102, thereby improving the working efficiency of the device.

[0052] In this example, the retention plate 2102 is spherical, and four layers of retention plates 2102 are evenly distributed inside the connecting shell 2. The retention plates 2102 in adjacent layers are staggered. The spherical shape of the retention plate 2102 makes the liquid surface area inside the retention plate 2102 larger. During the operation of the device, the staggered distribution of the retention plates 2102 can minimize the possibility of liquid falling to the bottom of the device when the liquid is injected, thereby improving the vaporization efficiency of the device.

[0053] It should be noted that this invention is a gate-type vaporized alcohol-based fuel distribution device. First, as... Figures 1-5As shown, during operation, the device is supported by the outer shell 1 and the connecting shell 2. The temperature and pressure inside the outer shell 1 are monitored in real time by a thermometer 5 and a pressure gauge 6. A pressure relief valve 7 allows the device to automatically release pressure when the internal pressure is too high, and the released gas is transported to the feed pipe 3 via the connecting pipe 11, enabling the reuse of vaporized alcohol groups. A notch 28 on the cover plate 27 allows the device to reuse vaporized alcohol groups while maintaining ventilation. During operation, the arrangement of the air inlet pipe 9 can be adjusted via the cross groove 14 and extension groove 15 on the support plate 13, allowing adjustment of the arrangement of the burner 10 on the right side of the air inlet pipe 9. A high-temperature resistant rubber support plate 18 is used to support the burner 10 (e.g., ...). Figure 2 As shown, when the burner 10 moves inside the cross groove 14 and the extension groove 15, the connecting strip 16 and the groove 17 can ensure that the burner 10 can move up and down smoothly and will not move in the length direction of the air inlet pipe 9. The connecting cover 12 at the front end of the burner 10, together with the heat insulation plate 20 of aerogel material, enables the device to insulate the furnace opening position, thereby improving the safety during use.

[0054] like Figure 1 and Figures 4-14 As shown, during operation, liquid fuel is fed through the feed pipe 3. The vaporization bed 21 allows the liquid fuel to remain on the surface of the retention pan 2102. Since the retention pan 2102 is divided into four layers with the upper and lower layers interleaved, the device ensures that the liquid fuel is retained as much as possible within each retention pan 2102. Combined with the electric heating tube 2101, the device can fully heat and vaporize the liquid fuel within the retention pan 2102. Some fuel flows through the mesh plate 26 to the bottom of the outer casing 1 for secondary heating. Furthermore, during operation, the amount of liquid fuel in the fixed cylinder 22 can raise the height of the float 23, allowing the support rod 24 to... The lever 25 drives the slide plate 1902 to move upward. The fluid channel 1904 on the slide plate 1902 passes through the connecting groove 1903 on the fixed plate 1901, allowing the device to utilize the return channel within the protruding fluid channel 1904 to achieve a throttling function. The more liquid fuel retained in the fixed cylinder 22, the higher the float 23, and the more obvious the throttling effect. This allows the device to adaptively adjust its throttling effect based on the amount of liquid retained, improving ease of use. The column 1905 on the device, in conjunction with the memory alloy spring 1906, enables the device to automatically raise the slide plate 1902 and the fluid channel 1904 when the temperature is too high, thereby improving the throttling performance of the device.

[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
