[0037] The gas-water input pipe 121 is connected with the output end of the hydrogen production device, and the mixed gas-liquid with a temperature of (0-200) DEG C and containing gas and water is input into the tank body 1. The input mixed gas-liquid is separated into gas and water, and the required gas is collected. The input water vapor is continuously supplied to the gas-water input pipe 121 and discharged upward. In the upward flowing process, the water vapor first contacts the lower end surface of the gas-water blocking separation plate 2, and then is attached to the lower end surface of the gas-water blocking separation plate 2.

The attachment of the water vapor realizes downward dripping under the gathering action, and sequentially flows into the lower liquid accumulation area 11 under the action of the angle inclination, so that the water vapor is preliminarily separated and then secondarily separated, and the water vapor separation effect is improved. The gas after the secondary separation enters the upper gas output area 13, and is finally discharged from the tank body through the gas outlet pipe 131, so that the prepared gas is collected, the water content in the gas is reduced, and the workload of subsequent drying of the prepared gas is reduced.
