1. A gas-liquid separator of a water electrolysis system, comprising:
a liquid feeding atomizer, including:
a liquid feeding pressurized tube, for receiving and pressurizing a gas-liquid mixed liquor after performing electrolytic reaction of the water electrolysis system; and
an atomizing spray head, which is connected to the liquid feeding pressurized tube, in which the atomizing spray head converts the gas-liquid mixed liquor after pressurized by the liquid feeding pressurized tube into a mist droplet gas-liquid mixture; and
a gas-liquid separation chamber, the liquid feeding atomizer being set above the gas-liquid separation chamber, wherein the atomizing spray head sprays the mist droplet gas-liquid mixture into the gas-liquid separation chamber, wherein the gas-liquid separation chamber comprises:
a spiral flowing way, which is set on an inner wall of the gas-liquid separation chamber, and when the mist droplet gas-liquid mixture is sprayed into the spiral flowing way, the spiral flowing way extends the time that the mist droplet gas-liquid mixture spraying into the gas-liquid separation chamber flows downwards to the bottom of the gas-liquid separation chamber;
an ultrasonic oscillation mechanism, set on an outer wall of the gas-liquid separation chamber, which is used for oscillating the mist droplet gas-liquid mixture in the gas-liquid separation chamber;
a stirrer, set at the bottom of the gas-liquid separation chamber, which is used to stir the mist droplet gas-liquid mixture accumulated in a lower layer of the gas-liquid separation chamber at a high speed;
an internal reservoir, located in the gas-liquid separation chamber, which is used to store and discharge a liquid in the mist droplet gas-liquid mixture after the gas-liquid separation; and
a filter mechanism, located at the top of the internal reservoir, which performs the gas-liquid separation for unbroken bubbles in the mist droplet gas-liquid mixture through a pore difference.
