[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a kind of liquefied gas tank gasification energy supplement water tank, including metal water tank, metal water tank is provided with metal hot air heat pipe, metal hot air heat pipe has metal spiral piece, the two ends of metal hot air heat pipe, one end is vertical, as gas outlet, one end is horizontal, as gas inlet, gas inlet is provided with spray gun outside.

[0006] Preferably, spray gun needs to be opposite gas inlet.

[0007] Preferably, spray gun is configured with flameout protection valve.

[0008] Preferably, the water surface in metal water tank is higher than metal hot air heat pipe, and higher than the bottom of liquefied gas tank body.

[0009] Compared with prior art, the utility model has the beneficial effects that:

[0010] 1. the utility model provides the heat that gasification needs to absorb by using gas combustion, simple structure, efficient, local materials are used;

[0011] 2. the utility model can keep the temperature of tank and internal liquefied gas of liquefied gas tank to a certain extent, alleviate the frost phenomenon of tank when liquefied gas tank is used in large flow, and the problem of liquefied gas flow and pressure drop;

[0012] 3. The utility model discloses a spiral plate is arranged in the metal hot air heat pipe, can good buffer effect of the hot air that enters the air inlet, increase the effective length of gas flow in the metal hot air heat pipe, increase the heat exchange area, make the heat be fully transferred to each place of the metal hot air heat pipe.

[0013] 4. The utility model discloses a direct heating is not used to liquefied gas tank body with electric energy, also not with flame, through the heating of medium water and keep the temperature of liquefied gas tank, safe and reliable, especially can use in the absence of power supply, wide application scene.

[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely below with the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the scope of the utility model.

[0019] Please refer to Figs. 1-3 A liquefied gas tank gasification energy supplement water tank, including metal water tank, be provided with metal hot air heat pipe in metal water tank, be provided with metal spiral sheet in metal hot air heat pipe. Metal hot air heat pipe is arranged in metal water tank with a certain length, and one end is horizontal and is air inlet, and one end is vertical and is air outlet.

[0020] The utility model discloses the temperature control and energy supplement of liquefied gas tank with medium water, when using, the liquefied gas tank is put into metal water tank in advance.

[0021] The spray gun is arranged at the air inlet, and the spray gun is opposite to the air inlet of the heat pipe. When the spray gun burns, hot air enters the metal hot air heat pipe through the air inlet, and the size of the fire can be adjusted by the valve of the spray gun. The fuel of the spray gun comes from the liquefied gas tank. When the gas in the liquefied gas tank is decompressed, a branch pipeline of the gas circuit is connected to the spray gun.

[0022] After the high-temperature air flow passes through the metal hot air heat pipe, the metal spiral fin plays a buffering role on the entering hot air, increases the effective heating length, and the heat is heated to the water in the metal water tank through the metal hot air heat pipe, when the liquefied gas tank is working, the tank body and the internal liquefied gas temperature is reduced, at this time, the water in contact with the tank body absorbs heat energy, maintains the gasification reaction efficiency, so that the tank surface temperature does not frost, ensures that the pressure of the liquefied gas is kept in the working pressure range required by the work.

[0023] In actual use, the water temperature and the liquefied gas tank temperature will not be higher than the ambient temperature, and the metal hot air heat pipe outlet is generally not hot air flow, the maximum heat of the imported heat is heated to the water body, converted into the heat energy absorbed by the liquefied gas gasification, and the heat exchange efficiency is very high.

[0024] The control of the water temperature in the metal water tank is mainly from the selection of the size of the spray gun and the firepower adjustment, so that the water temperature is kept at not higher than the ambient temperature, which avoids the danger that may be caused by directly heating the liquefied gas tank with the flame or electric energy, and increases the safety.

[0025] The spray gun is provided with an extinguishing protection valve, when the flame is extinguished accidentally, the extinguishing protection valve is sensed by the temperature sensor and the gas path is closed.

[0026] The above specific embodiments further illustrate the purpose, technical scheme and beneficial effects of the present application, and it should be understood that the above description is only a specific embodiment of the present application and is not used to limit the protection scope of the present application, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application should be included in the protection scope of the present application.
