Description

TECHNICAL FIELD

[0001] The utility model relates to the field of gasification gas supply device, especially to a rural LNG gasification gas supply device intelligent operation and maintenance system. BACKGROUND

[0002] The LNG gasification gas supply device is an integrated system for converting liquid natural gas (LNG) into gaseous natural gas (NG) and stably delivering it to the user end, and is widely used in the fields of city gas and industrial fuel, etc.

[0003] When the gas pressure in the liquefied petroleum gas transportation pipeline is too high or the pipeline needs to be repaired, the natural gas in the transportation pipeline needs to be diffused. In order to ensure that the density of the diffused gas is less than that of air and the diffused gas does not deposit on the ground to cause explosion, the diffused gas needs to be heated by the air temperature type gasifier before being diffused to the outside air to reduce the density of the diffused gas.

[0004] In the prior art, the air temperature type gasifier is a solar heater, which usually includes a gasifier, and the main heat exchange channel of the air temperature type gasifier is arranged on the gasifier. The current gasifier is fixed on the ground. Due to the different angles of sunlight at different times of the day, the heat exchange channel of the air temperature type gasifier cannot always face the sunlight, resulting in low heating efficiency of the air temperature type gasifier for the diffused gas and unstable heating effect of the diffused gas. In addition, even if the angle of the gasifier is manually adjusted, the heat exchange channel on the gasifier is still in a fixed state, that is, only one side of the heat exchange channel will be irradiated by the sun, which easily shortens the service life of the heat exchange channel.
