Hydrogen purification system based on super-hydrophilic A type molecular sieve

The invention discloses a hydrogen purification system based on a super-hydrophilic A-type molecular sieve. The hydrogen purification system comprises a deoxidation tower, a cooler, a drying tower, a heat exchanger and a gas-water separator, a hydrophilic wire mesh demister (14) is mounted at the upper part of the gas-water separator, and a hydrophobic coating (15) is arranged in a partial region in the gas-water separator; and the drying tower is filled with a kaolin synthesized super-hydrophilic A type molecular sieve adsorbent. The molecular sieve synthesized from kaolin is used as an adsorbent of a hydrogen purification system, so that the synthesis cost of the molecular sieve is reduced, the adsorption efficiency of hydrogen purification equipment is improved, and the space of a drying tower is reduced. Besides, a hydrophilic wire mesh demister is additionally arranged at the top of the gas-water separator, and local hydrophobic modification is carried out on the inner wall of the gas-water separator, so
