Embodiment Construction
[0028] Such as figure 1 As shown, the present invention discloses a device for preparing hydrogen gas for fuel cells by using the degassing of synthetic ammonia. The upper part of the buffer tank 1 is provided with a pressure measuring instrument, and the lower part of the buffer tank 1 is provided with a nitrogen purge replacement interface. The material outlet 102 of the buffer tank is connected to the material inlet 201 of the washing tower. The washing tower 2 is equipped with auxiliary equipment such as a soft water tank, water, and washing water recovery devices, and has corresponding pipelines connected to each other to ensure sufficient water during the washing process and subsequent treatment of washing water. The material outlet 202 of the washing tower is connected to the material inlet 301 of the dryer. The dryer 3 is an automatic cycle regeneration adsorption dryer, which is mainly composed of an adsorption tower, a condenser, a gas-water separator, a forced circu...
