Abstract
Description
technical field
[0001] The invention relates to a gas filling method and device for a compressed natural gas gas filling substation, in particular to an additional high-pressure gas filling method and device. Background technique
[0002] At present, the gas filling method and device of the existing compressed natural gas filling sub-stations at home and abroad are three-line sequential supply with three sets of low, medium and high-pressure gas cylinder groups and corresponding gas supply pipelines connected with the three-line intake type gas filling machine. gas system. According to the sequence of low, medium and high pressure, the method of getting gas from the gas cylinder group and filling gas vehicles uses a three-line filling machine, which is usually called a three-line sequential filling method. In reality, when gas vehicles are refueled, the amount of natural gas remaining in the vehicle cylinders varies, and the pressure of the remaining gas is different, so no...
Examples
Embodiment Construction
[0010] In the above drawings, an additional high-pressure gas supply system 2 is added to the three-line sequential gas supply system 1 of the gas filling sub-station, connected to the multi-line air intake type automatic sorting gas filling machine 3, which is turned on when it is necessary to maintain the normal gas filling pressure and gas filling Additional high-pressure air supply system, multi-line air intake type automatic sorting air dispenser 3 takes air in the order of low, medium, high pressure, and additional high pressure to add air to the outside.
