The invention relates to the technical field of gas supply pipeline layout, and provides a vehicle-mounted liquid hydrogen supply system which comprises a hydrogen storage tank, and a liquid inlet pipeline, a liquid outlet pipeline, a pressurizing unit and a gas phase outlet are connected to the hydrogen storage tank; the gas phase outlet is connected with an emptying pipeline; the blow-down pipeline is connected with a blow-down purging pipe in parallel; the liquid outlet pipeline is connected with a liquid outlet purging pipe, and the liquid outlet purging pipe is further connected to a blow-down pipeline; the liquid inlet pipeline is connected with a liquid inlet purging pipe, and the liquid inlet purging pipe is further connected to the blow-down pipeline. Therefore, by arranging a plurality of purging pipes, non-hydrogen gas in the tank and the pipeline can be effectively replaced; and nitrogen and oxygen solid particles are prevented from blocking a pipeline, and the safety of a gas supply system is improved.

    本发明涉及供气管路布局技术领域,提供了一种车载液氢供气系统,包括储氢罐体,所述储氢罐体上连接有进液管路、出液管路、增压单元以及气相出口;所述气相出口连接放空管路;所述放空管路上并联有放空吹扫管;所述出液管路连接出液吹扫管,所述出液吹扫管还连接在放空管路上;进液管路上连接有进液吹扫管,所述进液吹扫管还连接在放空管路上。借此,本发明通过设置多个吹扫管,可有效将罐内和管路内非氢气体置换掉;避免出现氮、氧固体颗粒,堵塞管路,提高了供气系统的安全性。
