The invention relates to a gas-charging system of a gas station, and particularly relates to an automatically-adjusting gas-charging system of coke oven gas mixed with natural gas, which comprises a natural gas desulphurization device (1); a gas outlet of the natural gas desulphurization device (1) is connected with a gas inlet of a natural gas dehydration device (2) through a pipeline; a gas outlet of the natural gas dehydration device is connected with a gas inlet of a natural gas storage tank (4) through a pipeline via a natural gas compressor (3); a gas outlet of the natural gas storage tank (4) is connected with a natural gas inlet (6) of a gas mixing storage tank (7) through a pipeline via a first pneumatic stop valve (5). The gas-charging system of the invention is reasonable in design, combines a mixed gas composition on-line analysis device, a DCS control system and the pneumatic stop valve together, realizes not only on-line gas composition detection and analysis, but also centralized monitoring and control of the operation condition of the gas station, enables the hydrogen content in the mixed gas to be maintained at about 20%, ensures the gas source gas quality, and improves the performance and thermal efficiency of engines.
Description
technical field [0001] The invention relates to a gas filling system of a gas filling station, in particular to an automatic adjustment gas filling system of coke oven gas mixed with natural gas. Background technique [0002] As a kind of clean energy, natural gas has aroused widespread attention of domestic and foreign scientific researchers in recent years. Around 2013, "smog" appeared in a large area in North China, and it is imminent to vigorously develop and promote clean fuel vehicles. Natural gas vehicles reduce the emission of carbon and other pollutants to a certain extent, and alleviate the contradiction of energy demand, but natural gas has problems such as low engine thermal efficiency, narrow ignition range, and slow flame propagation speed. Hydrogen hybrid natural gas vehicles combine the advantages of hydrogen and natural gas, which not only improves the combustion speed of gas and the thermal efficiency of the engine, but also has the advantages of economy a...
