Abstract

The invention discloses a hydrogen filling system and method with an automatic flow regulation function for a long pipe trailer. The system comprises a first water chilling unit, a valve, corresponding to a hydrogen filling pipeline, of the first water chilling unit, the 20 Mpa long pipe trailer, a second water chilling unit, a valve, corresponding to a hydrogen filling pipeline, of the second water chilling unit and a 30 Mpa long pipe trailer. Wherein the first water chilling unit is connected with the 20Mpa long pipe trailer through a valve, corresponding to the hydrogen filling pipeline, of the first water chilling unit; the second water chilling unit is connected with the 30Mpa long pipe trailer through a valve, corresponding to the hydrogen filling pipeline, of the second water chilling unit; the valve, corresponding to the hydrogen filling pipeline, of the first water chilling unit and the valve, corresponding to the hydrogen filling pipeline, of the second water chilling unit are controlled through a filling station control system. The method comprises the steps of pipeline selection, nitrogen purging replacement, hydrogen purging replacement, rapid filling and filling stopping. The system has the beneficial effects that the operation cost and the manual operation error rate are reduced in the automatic and rapid hydrogen filling process; therefore, the service life of the water chilling unit is prolonged.

Description

technical field [0001] The invention relates to the field of hydrogen charging systems of hydrogen refueling stations, in particular to a hydrogen filling system and method for long-tube trailers with automatic flow adjustment. Background technique [0002] With the rapid development and application of hydrogen fuel cell vehicles in China, the demand for the construction of hydrogen production stations that provide hydrogen sources for fuel cells is also increasing. The hydrogen produced by the hydrogen production station is usually transported to the hydrogen refueling station by a long-tube trailer. Therefore, how to safely and quickly fill the hydrogen into the hydrogen long-tube trailer is a problem worthy of attention. The working pressure of the commonly used long-tube trailer gas cylinders is 20MPa and 30MPa, and the filling columns with working pressures of 20MPa and 30MPa are usually used for filling, and independent filling columns with different working pressures ...
