The inlet pipe 11 allows the gas to smoothly enter the gas-liquid separator 10, while the plate heat exchanger 12 is used to regulate the gas temperature to achieve the best separation effect. The drying mechanism 2 further removes moisture from the gas, ensuring the dryness of the gas.
[0034] Flow meter 15 monitors the gas flow rate, ensuring that the gas flow is within a safe and effective range. Back pressure valve 16 controls the gas back pressure to prevent excessively high system pressure caused by excessively rapid gas flow. Hydrogen detector 17 monitors the hydrogen concentration in the gas in real time, ensuring gas safety. The entire system, through precise control and monitoring, ensures the high efficiency and safety of the gas purification process.

[0044] Working principle: Hydrogen gas is introduced through inlet pipe 11 and enters gas-liquid separator 10 through plate heat exchanger 12 to achieve gas-liquid separation. Water falls to the bottom of gas-liquid separator 10, and gas enters vertical pipe 203 through pipe a13 and is discharged from exhaust port 2031. The gas comes into contact with the cooled curved pipe 211, causing the water in the gas to liquefy upon cooling. The water flow collects in tank 201, and the gas passes through vent hole 2211 on circular shell 221. Desiccant 222 dries the gas and enhances the gas purification effect.
[0045] After unscrewing bolt 231, the sealing ring 232 can be rotated to align the positions of the drainage trough 2321 and the drain outlet 2011. Water at the bottom of tank 201 flows out along the drainage trough 2321 and the drain outlet 2011, thus achieving water collection and discharge.
[0046] Pull the handle 216 to pull out the drawer box 215, put ice cubes into the drawer box 215, and then push the drawer box 215 into the push-open groove 2121.
