Description

Technical Field

[0001] This utility model relates to the technical field of light hydrocarbon gas production and supply equipment, specifically to a gasification tank heating device. Background Technology

[0002] Light hydrocarbon gasification equipment is a specially developed system that utilizes petroleum and chemical byproducts such as liquid light hydrocarbon C5 and liquefied petroleum gas residue as raw materials. Without adding any additives, it produces light hydrocarbon fuel gas that meets national standards by adding a suitable amount of air to the gasification tank at room temperature and relatively low operating pressure. This fuel gas is then safely transported to residential users through a pipeline system to meet their daily energy needs. During the gasification process, the light hydrocarbon oil loses a significant amount of heat. If this heat is not replenished in time to maintain a constant temperature, the amount of oil molecules carried away by the air will gradually decrease, leading to a drop in the calorific value of the fuel gas and compromising its usability. Therefore, a heating device is required to reheat the light hydrocarbon oil.

[0003] CN220579213U discloses a heating device for a light hydrocarbon gasification tank, comprising a tank body with a gas output pipe, a fuel oil delivery pipe, and an air delivery pipe. A heating chamber is located below the tank body, filled with a heat-conducting medium. Heaters are installed around the periphery of the heating chamber, and heat exchange tubes are located inside the tank body. A circulation pump is located below the heating chamber, with its input end connected to the output end of the heat exchange tubes. The upper surface of the heating chamber is connected to the input end of the heat exchange tubes, and the output end of the circulation pump is connected to the lower surface of the heating chamber. The heat-conducting medium is pressurized into the heating chamber by the circulation pump for heating. The heated heat-conducting medium then flows back to the circulation pump through the heat exchange tubes, thus forming a cycle for continuous heating.

[0004] However, existing vaporizer designs heat the tank body by installing heat exchange tubes inside, then introduce light hydrocarbon oil and air into the tank to heat the light hydrocarbon oil. But this heating method suffers from uneven heat conduction, resulting in insufficient heating of the light hydrocarbon oil during vaporization, which in turn affects output stability and reduces heating efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a gasification tank heating device to solve the problem of uneven heat conduction in the existing gasification tank heating method, which affects the stability of output and reduces heating efficiency.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a heating device for a vaporization tank, comprising: a tank body and a material guiding structure. The tank body has a liquid inlet, a gas inlet, and a discharge outlet. A heating chamber and a mixing chamber are formed inside the tank body. The mixing chamber is connected to the discharge outlet and the liquid inlet. The material guiding structure is disposed within the heating chamber and has a heating channel formed inside it. One end of the heating channel corresponds to the liquid inlet, and the other end extends away from the mixing chamber to guide the liquid substance to flow away from the mixing chamber. The gas inlet is connected to the heating channel. The heating chamber is filled with a heating medium for heating the reverse-flowing liquid substance.

[0011] In some embodiments, the tank body is further provided with a medium inlet and a medium outlet, both of which are connected to the heating chamber and are used to fill and discharge heating medium into the heating chamber, respectively.

[0012] In some embodiments, a plurality of flow guides are arranged sequentially from the feed chamber to the mixing chamber in the heating chamber. The plurality of flow guides are alternately connected to both sides of the inner wall of the tank to divide the heating chamber into an S-shaped channel. The medium inlet and the medium outlet are respectively located at the two ends of the S-shaped channel.

[0013] In some embodiments, the mixing chamber includes an inner cavity and an outer cavity, the inner cavity being in communication with the heating channel, the outer cavity surrounding the inner cavity, and a heating structure being provided inside the outer cavity for heating the raw materials in the inner cavity.

[0014] In some embodiments, a heat-conducting channel is formed within the heating structure. The heat-conducting channel has a heating medium inlet end and a heating medium outlet end. The heating medium inlet end and the heating medium outlet end are respectively used to guide the heating medium into and out of the heat-conducting channel to heat the raw materials in the inner cavity.

[0015] In some embodiments, the heat-conducting channel is connected to the heating channel through the heating medium discharge end, and is used to deliver the heating medium into the heating channel.

[0016] In some embodiments, the heating structure includes a heat-conducting spiral tube disposed within the outer cavity and spirally wound around the outside of the inner cavity.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] To address the issue of uneven heat conduction in the heating method of vaporization tanks, which affects output stability and reduces heating efficiency, this invention provides a vaporization tank heating device that increases the contact area and time between the liquid substance and the heating medium, ensuring sufficient heating, achieving uniform heating of the liquid substance, and improving heat exchange efficiency.

[0030] It should be noted that the gasification tank heating device described in this utility model is used for, but not limited to, the mixing and preparation of light hydrocarbon fuels. For ease of explanation, this utility model only uses the application of the gasification tank heating device to the mixing and preparation of light hydrocarbon fuels as an example. The principle of the gasification tank heating device in other types of gas-liquid mixing work is essentially the same as that in the mixing and preparation of light hydrocarbon fuels, and will not be described in detail here.

[0031] Please see Figure 1 and Figure 2 The gasification tank heating device includes: a tank body 1 and a material guiding structure 2. The tank body 1 has a liquid inlet, a gas inlet and a discharge outlet. It has a heating chamber 11 and a mixing chamber 12 inside. The mixing chamber 12 is connected to the discharge outlet and the liquid inlet. The material guiding structure 2 is set in the heating chamber 11. It has a heating channel 201 inside. One end of the heating channel 201 corresponds to the liquid inlet and the other end extends away from the mixing chamber 12 to guide the liquid substance to flow away from the mixing chamber 12. The gas inlet is connected to the heating channel 201. The heating chamber 11 is filled with a heating medium to heat the liquid substance flowing in the opposite direction.

[0032] In this device, tank 1 has a liquid inlet, a gas inlet, and a discharge port. Fuel and air can enter tank 1 through the liquid inlet and gas inlet respectively, be heated and mixed, and then discharged through the discharge port. The extension direction of the heating channel 201 of the material guiding structure 2 allows the liquid substance to form a certain flow path within the heating chamber 11. The liquid substance can flow in the opposite direction along the heating channel 201, and during the flow, it can enter the heating chamber 11 to fully exchange heat with the heating medium inside the heating chamber 11, thereby ensuring that the liquid substance can reach the required temperature during the heating process. After the fuel is heated and vaporized, it can return to the mixing chamber 12 to be mixed more evenly with the air, and finally be discharged through the discharge port.

[0033] To facilitate the transport of raw materials, please refer to [link / reference]. Figure 1In this embodiment, an inlet pipe and an outlet pipe are provided on the outer side of the tank body 1. The inlet pipe is connected to the feed port and includes a fuel delivery pipe 14 and an air delivery pipe 15, which are respectively connected to the fuel tank and the air compressor to provide the fuel and air required for heating into the heating chamber 11. The outlet pipe is a gas output pipe 16, which is used to discharge the mixed gas to external equipment or processing systems. The discharge end of the fuel delivery pipe 14 is located above the material guiding structure 2, the air delivery pipe 15 is located below the material guiding structure 2, and the gas output pipe 16 is connected to the mixing chamber 12. During operation, light hydrocarbon oil enters the feed chamber through the fuel delivery pipe 14, and air enters the feed chamber through the air delivery pipe 15. Under the guidance of the heating channel 201 of the material guiding structure 2, the light hydrocarbon oil and air enter the heating chamber 11 from different directions. The light hydrocarbon oil flows from top to bottom, while the air flows from bottom to top. The two form convection in the heating chamber 11. This convection not only improves the heat exchange efficiency but also promotes the initial mixing of the light hydrocarbon oil and air. The heating medium is uniformly distributed within the heating chamber 11, effectively heating the flowing liquid light hydrocarbon oil and air to ensure complete vaporization of the light hydrocarbon oil. As the light hydrocarbon oil gradually vaporizes, it further mixes with air within the heating chamber 11, forming a homogeneous fuel gas mixture. Finally, this mixture enters the fuel gas output pipe 16 through the mixing chamber 12 and is discharged from the outlet for use by external equipment or processing systems.

[0034] It should be noted that in this embodiment, the heating medium can be water, steam or other suitable heat carriers. The heating medium is heated by an external heat source and then the heat is transferred to the liquid substance.

[0035] To increase the heat exchange area, please refer to Figures 2 to 4 In this embodiment, the material guiding structure 2 includes a plurality of material guiding components 21, which are evenly arranged in the heating chamber 11, and each material guiding component 21 has a heating channel 201 formed inside.

[0036] In one embodiment, the feed guide 21 employs a pipeline structure to guide light hydrocarbon oil and air. It includes a guide pipe 211, with several guide pipes 211 arranged in parallel. Two transversely arranged baffles 13 are positioned within the tank body 1 corresponding to the feed guide structure 2, forming a heating chamber 11 between the two baffles 13 to isolate the heating chamber 11 from the mixing chamber 12. Both ends of the guide pipes 211 are fixedly connected to the two baffles 13. To further improve heat exchange efficiency, the guide pipes 211 are spiral tubes, with their spiral sections located within the heating chamber 11. The multiple parallel spiral tubes are evenly distributed. This spiral design not only increases the path length of the raw material within the heating chamber 11 but also improves the heat exchange efficiency between the raw material and the heating medium. This ensures that the raw material is evenly distributed and fully heated within each feed guide 21.

[0037] It should be noted that the guide tube 211 can be in various forms. In addition to the spiral tube mentioned above, it can also be an S-shaped tube, a corrugated tube, or other tube types that can increase the path length and promote heat exchange. Guide tubes 211 of different shapes can form complex flow channels in the heating chamber 11, allowing the liquid substance to have a more thorough and uniform heat exchange with the heating medium during the flow process.

[0038] Furthermore, to improve the uniformity of light hydrocarbon oil distribution within each guide pipe 211, a flow equalization plate 17 is provided between the fuel delivery pipe 14 and the feed structure 2. The function of the flow equalization plate 17 is to evenly distribute the fuel input from the fuel delivery pipe 14 into each guide pipe 211, thereby improving the uniformity and stability of the entire heating process.

[0039] In some possible embodiments, the heating chamber 11 is provided with a medium inlet and a medium outlet, which are used to fill and discharge the heating medium into the heating chamber 11, respectively. A plurality of guide members 22, which are guide plates 221, are sequentially arranged in the heating chamber 11 from the direction of the feeding chamber to the direction of the mixing chamber 12. These guide plates 221 are alternately connected to both sides of the inner wall of the tank 1 to divide the heating chamber 11 into S-shaped channels. The medium inlet and medium outlet are respectively located at the two ends of the S-shaped channels. The S-shaped channels allow the heating medium to circulate within the heating chamber 11, further improving the heat exchange efficiency.

[0040] In this embodiment, please refer to Figure 2 and Figure 5 The mixing chamber 12 includes an inner chamber 121 and an outer chamber 122. The inner chamber 121 and the outer chamber 122 are separated by an isolation cylinder 123. The inner chamber 121 is connected to the heating channel 201. The outer chamber 122 is arranged around the inner chamber 121, and a heating structure 3 is provided in the outer chamber 122. The heating structure 3 is used to heat the raw materials in the inner chamber 121.

[0041] In one embodiment, please refer to Figure 2 and Figure 5 The heating structure 3 has a heat-conducting channel 301, which has a heating medium inlet and a heating medium outlet. The heating medium inlet and outlet are used to guide the heating medium into and out of the heat-conducting channel 301, respectively, to heat the raw material in the inner cavity 121. Furthermore, the heating medium outlet of the heat-conducting channel 301 is connected to the medium inlet of the heating channel 201, allowing the heating medium to circulate between the heating channel 201 and the heat-conducting channel 301, thus improving energy utilization efficiency.

[0042] To further improve heating efficiency, in some possible embodiments, the heating structure 3 includes a heat-conducting spiral tube 31, which is disposed within the outer cavity 122 and spirally wound around the outside of the inner cavity 121. When the heating medium passes through the heat-conducting spiral tube 31, the heat it carries can be effectively transferred to the raw material in the inner cavity 121, ensuring uniform heating of the raw material in the inner cavity 121. An energy storage sleeve 32 is provided on the outside of the isolation cylinder 123. The energy storage sleeve 32 is in contact with and adheres to the heat-conducting spiral tube 31, and is used to store the heat transferred by the heating medium and release it to the raw material in the inner cavity 121 when needed, thereby further improving the utilization rate of thermal energy and heating efficiency. The energy storage sleeve 32 is made of a material with high thermal conductivity and strong heat storage capacity, such as high-temperature resistant graphite or special alloys, to ensure that it can operate stably for a long time in a high-temperature environment, while effectively storing and releasing thermal energy.

[0043] Specifically, the heating medium inlet of the heat-conducting spiral tube 31 is provided with a medium inlet pipe 4, and its heating medium outlet is connected to the medium inlet of the heating chamber 11 through a connecting pipe 5. The medium outlet of the heating chamber 11 is provided with a medium outlet pipe 6. The heating medium first enters the heat-conducting spiral tube 31 through the medium inlet pipe 4, flows inside the heat-conducting spiral tube 31, and exchanges heat with the raw material in the inner cavity 121. Then it enters the interior of the heating chamber 11 through the connecting pipe 5, where it continues to heat the liquid substance. Finally, it is discharged through the medium outlet pipe 6 and then heated by a heater before being supplied to the heat-conducting spiral tube 31, forming a complete heating cycle.

[0044] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail below: During operation, light hydrocarbon oil and air enter the feed inlet of tank 1 through fuel delivery pipe 14 and air delivery pipe 15, respectively. Fuel delivery pipe 14 transports the light hydrocarbon oil to the top of the feed guide structure 2, while air delivery pipe 15 transports air to the bottom of the feed guide structure 2. Under the action of gravity, the light hydrocarbon oil flows from top to bottom along the heating channel 201 of the feed guide structure 2, while the air flows from bottom to top along the heating channel 201 under pressure. This convection method not only increases the contact area between the light hydrocarbon oil and air but also promotes their initial mixing.

[0045] Inside the heating chamber 11, the heating medium is heated by an external heat source and transfers heat to the flowing light hydrocarbon oil and air. When the fuel gas mixture reaches the mixing chamber 12, it has already undergone sufficient heating and mixing. At this point, the fuel gas mixture enters the fuel gas output pipe 16 through the mixing chamber 12 and is discharged from the outlet for use by external equipment or processing systems.

[0046] This invention, through the design of the tank body 1 and the material guiding structure 2, allows the heating medium filled in the heating chamber 11 to effectively transfer heat to the liquid substance, enabling it to heat up rapidly. The material guiding structure 2 creates a specific flow path for the liquid substance within the heating chamber 11, increasing the contact area and time between the liquid substance and the heating medium, ensuring thorough heating, achieving uniform heating of the liquid substance, and improving heat exchange efficiency.

[0047] The material guiding structure 2 employs several material guiding components 21 evenly arranged within the heating chamber 11. Each material guiding component 21 has a heating channel 201 inside, increasing the heat exchange area and improving heat exchange efficiency. Furthermore, the heating structure 3 located within the mixing chamber 12 introduces the heating medium into the heating structure 3 through the heat conduction channel 301, providing secondary heating to the raw materials in the inner chamber 121. This ensures sufficient heating of the raw materials and improves the quality of the light hydrocarbon fuel gas.
