Gas-liquid separator suitable for microgravity

A disclosed gas-liquid separator suitable for microgravity comprises a shell, the shell interior forms a water-collecting chamber and a gas-collecting chamber, and the shell is inside provided with a hydrophilic porous material area, and the gas-liquid separator is characterized in that a worm-shaped inner chamber is formed in the hydrophilic porous material area in the shell, a cylindrical partial space at the center of the inner chamber forms a hydrophobic porous material area which is filled with a hydrophobic porous material, a partial space at the circumference in the inner chamber forms a spiral mixed-fluid channel, one end of the mixed-fluid channel is connected to the exterior of the shell through a pipe and a mixed-fluid inlet is formed, and left and right slopes, where the hydrophilic porous material area is arranged, formed by the inner wall of the mixed-fluid channel possesses bulges which are successively staggered at the left and right, and the bulges form a plurality of hydrophilic porous mater
