Through the patent technology product "light hydrocarbon gas generator", the liquid light hydrocarbon is converted into gaseous mixed gas by physical gasification, and then transported to the end user through the pipeline. This kind of gas has high calorific value, clean combustion emission, and has the advantages of more convenient and safe transportation, storage and distribution.

[0003] The existing patent (announcement number: CN208124594U) discloses a light hydrocarbon efficient gasification device, and the technical scheme is as follows: a light hydrocarbon storage tank, a gasifier connected with the light hydrocarbon storage tank, a boiler connected with the gasifier, and a water tank are provided, a first pump is arranged on the pipeline between the light hydrocarbon storage tank and the gasifier, a steam outlet is arranged on the boiler, a steam pipeline is arranged on the boiler, the steam pipeline comprises a gas inlet communicated with the steam outlet and a gas return port communicated with the internal cavity of the boiler, the steam pipeline is partially located in the water tank, a first water pipe is arranged on the water tank, the first water pipe comprises a first water inlet and a first water outlet located in the water tank, the first water pipe is partially located in the gasifier, and a second pump is arranged on the first water pipe. The light hydrocarbon efficient gasification device can recycle the heat energy contained in the steam, has high energy utilization rate, and saves resources.

[0004] Although the above-mentioned scheme increases the contact area with the liquid light hydrocarbon by arranging the spiral heat exchange pipe in the gasifier, the liquid light hydrocarbon has fluidity, and the heat-exchanged liquid light hydrocarbon will flow in the gasifier, so that the heat-exchanged liquid light hydrocarbon will be mixed with the non-heat-exchanged liquid light hydrocarbon, and the mixed liquid light hydrocarbon needs to be heat-exchanged again by the heat exchange pipe, which affects the heat exchange efficiency of the liquid light hydrocarbon and increases the energy consumption of the light hydrocarbon gasification. Practical new type content

[0005] In view of the defects of the prior art, the present application provides a light hydrocarbon efficient gasification device, which has the advantages of reducing the space for liquid light hydrocarbon to flow in the gasification chamber, avoiding that the heat-exchanged liquid light hydrocarbon is too far away from the heat exchange pipe, improving the heat exchange efficiency of the heat exchange pipe for the liquid light hydrocarbon, and reducing the energy consumption of the light hydrocarbon gasification, and solves the problems that although the spiral heat exchange pipe is arranged in the gasifier to increase the contact area with the liquid light hydrocarbon, the liquid light hydrocarbon has fluidity, the heat-exchanged liquid light hydrocarbon will flow in the gasifier, so that the heat-exchanged liquid light hydrocarbon will be mixed with the non-heat-exchanged liquid light hydrocarbon, and the mixed liquid light hydrocarbon needs to be heat-exchanged again by the heat exchange pipe, which affects the heat exchange efficiency of the liquid light hydrocarbon and increases the energy consumption of the light hydrocarbon gasification.
