The liquid is generally set to be pure water, the electrolyte particles are diluted after being absorbed by the pure water, the gas can only take the diluted electrolyte particles with low concentration when being discharged from the liquid, the solute amount in the gas is very small, and most of the solute is remained in the liquid. During the process of continuously absorbing the solute, the solubility of the liquid is gradually increased, and at the moment, the liquid can be diluted by adding purified water. In summary, the liquid is set to be lower than the electrolyte solution and can play the purpose of absorbing and diluting the electrolyte particles drifted out from the electrolyte, and then the solute that reduces the electrolyte is discharged to the quality outside the deoxidization module.

For ease of understanding, the following illustrates how the oxygen scavenging module consumes oxygen in the enclosed space.
