Description

Technical Field

[0001] The utility model relates to the technical field of liquefied natural gas, in particular to a liquefied natural gas gasification assembly. Background Art

[0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere and lithosphere. The definition of natural gas that has long been commonly used is a narrow definition based on energy, which refers to a mixture of hydrocarbons and non-hydrocarbon gases naturally stored in strata. In petroleum geology, it usually refers to oilfield gas and gasfield gas, which is mainly composed of hydrocarbons and contains non-hydrocarbon gases.

[0003] For example, the liquefied natural gas gasification assembly recorded in the patent with patent announcement number CN108386720 B, which records the following scheme: the temperature sensing module monitors the temperature in the heating pipe in real time. When the temperature in the heating pipe is lower than 220°C, the PLC control cabinet controls the relay to start the heating module, and the heating wire starts working and heats the air in the heating pipe. When the temperature in the heating pipe is higher than 250°C, the PLC control cabinet controls the relay to shut down the heating module, and the heating wire stops heating the air in the heating pipe, so that the temperature in the heating pipe is always kept in a constant temperature state, the natural gas in the gas pipeline is heated, and the combustion efficiency of the natural gas is improved.

[0004] In the above case, when the electric heating wire heats the gas pipeline, the heating range is small, which makes the gas pipeline heated unevenly and the upper and lower temperatures inconsistent. In addition, the electric heating wire directly heats the pipeline, which can easily cause damage to the pipeline.

[0005] Based on this, a liquefied natural gas gasification assembly is now provided to eliminate the drawbacks of existing devices. Utility Model Content
