[0019] The present utility model discloses a fuel auxiliary heating device. The following will further describe the specific embodiments of the present utility model in conjunction with the preferred embodiment (Embodiment 1) with reference to the Figures 1 to 5 drawings.

[0020] With reference to the Figures 1 to 5 , Figures 1 to 4The fuel-assisted heating device is shown from different perspectives respectively. Figure 5 The emergency burner is shown.

[0021] Example 1.

[0022] Preferably, the fuel-assisted heating device includes:

[0023] A tank body 100, which includes an outer tank shell 130 and an inner tank shell (not shown in the figure). A heat insulation layer (not shown in the figure) is provided between the outer tank shell 130 and the inner tank shell, so that the outer tank shell 130 and the inner tank shell are not connected, and the heat insulation layer and the inner tank shell are not connected. The fuel input through the input pipeline 110 is placed inside the inner tank shell to prevent fuel leakage into the heat insulation layer and avoid potential safety hazards. The tank body 100 also includes an input pipeline 110 and an output pipeline 120. The input pipeline 110 and the output pipeline 120 are respectively connected to the inner tank shell, and the input pipeline 110 and the output pipeline 120 are respectively fixedly connected to the outer tank shell 130. The relative height of the input pipeline 110 is higher than the relative height of the output pipeline 120 (both are relative heights with respect to the horizontal plane), so that the fuel in the input pipeline 110 can flow fully inside the inner tank shell and then be output through the output pipeline 120. Under the action of the heat insulation layer, the temperature of the fuel output through the output pipeline 120 is kept relatively stable as much as possible, and preparatory work is done in advance for subsequent fuel infusion and other processes.

[0024] (Two) emergency burners 200. The emergency burners 200 and the input pipeline 110 are respectively located on different sides of the tank body 100 (the input pipeline 110 and the output pipeline 120 are located on the same side of the tank body 100, and the emergency burners 200 are located on the other side of the tank body 100 to avoid the influence of the emergency burners 200 burning fuel on the input pipeline 110 and the output pipeline 120 as much as possible and reduce potential safety hazards). The emergency burners 200 are connected to the inner tank shell and fixedly connected to the outer tank shell 130, so that in case of excessive pressure in the inner tank shell, the emergency burners 200 can burn and consume part of the fuel to reduce potential safety hazards.

[0025] Among them, the emergency burner 200 includes an emergency output pipeline 210 and a gas turbine 220. The emergency output pipeline 210 is fixedly connected to the outer tank shell 130. One end of the emergency output pipeline 210 is connected to the inner tank body, and the other end of the emergency output pipeline 210 is connected to the gas turbine 220, so that the fuel overflowing into the emergency output pipeline 210 can be quickly consumed by the gas turbine 220.

[0026] Among them, the gas turbine 220 includes a casing 222 and a number of blades 221 placed inside the casing 222. The casing 222 is fixedly connected to the emergency output pipeline 210.

[0027] Among them, the gas turbine 220 further includes a driving mechanism 223. The driving mechanism 223 is partially built into the casing 222, and the driving mechanism 223 is in transmission connection with the blade 221.

[0028] Among them, the fuel auxiliary heating device further includes (two) tank racks 150, and the tank racks 150 are fixedly connected to the outer layer tank body 130.

[0029] Embodiment 2.

[0030] On the basis of Embodiment 1, Embodiment 2 further includes the following technical solutions.

[0031] Specifically, a heater (not shown in the figure) is built into the heat insulation layer. Under the action of the heater, not only the temperature of the fuel output by the output pipeline 120 is kept relatively stable, but also the temperature of the fuel in the inner layer tank body can be increased, thereby increasing the temperature of the fuel output by the output pipeline 120, and preparing for subsequent fuel infusion and other processes in advance (for example, under adverse climatic conditions such as snowy weather).

[0032] Specifically, the tank body 100 further includes a control panel 140. The control panel 140 is electrically connected to the heater, and the control panel 140 is fixedly connected to the outer layer tank shell 130, so as to adjust the heating temperature of the heater through the control panel 140.

[0033] It is worth mentioning that the specific selection and other technical features of the driving mechanism 223 involved in the patent application of the present utility model should be regarded as the prior art. The specific structure, working principle, possible control methods, and spatial arrangement methods of these technical features can be selected conventionally in the art, and should not be regarded as the inventive point of the patent of the present utility model, and the present utility model will not be further specifically elaborated.
