Abstract

The invention discloses a hydrogen refueling station gas discharging column system which comprises a hydrogen inlet pipe, wherein the hydrogen inlet pipe is sequentially connected with a filter, a pneumatic input valve, a pneumatic output valve, a pneumatic emergency stop valve and a compressor. A manual discharging needle valve, a hydrogen branch safety valve and a one-way valve are connected between the pneumatic input valve and the pneumatic output valve, and the one-way valve is sequentially connected with a pneumatic purging valve and a nitrogen inlet pipeline. The manual discharging needle valve and the hydrogen branch safety valve are connected with an emptying pipeline. A nitrogen connector and a hydrogen connector are arranged, after the system is installed, nitrogen is used for purging the system to remove air in a pipeline, then hydrogen is used for purging the system to remove nitrogen in the pipeline, and the safety of the system is improved through purging of the two loops.

Description

technical field [0001] The invention relates to the field of hydrogenation, in particular to a hydrogenation station unloading column system. Background technique [0002] Hydrogen energy is a zero-carbon green new energy, which is in line with my country's clean, low-carbon, safe and efficient energy policy. Hydrogen fuel cell vehicles are also the object of key support from the state. They have worry-free battery life and zero carbon emissions. They are veritable "carbon reduction experts". Therefore, hydrogen refueling stations have become an important infrastructure for the promotion and popularization of hydrogen fuel cell vehicles. In recent years, the number of hydrogen refueling stations has also been increasing, and various demonstration activities have been carried out all over the country. The construction and demonstration operation activities of these hydrogen refueling stations have accumulated a lot of data and experience for the future. [0003] At present,...
