Background

The membrane method is used for separating air, namely the diffusion rates of oxygen and nitrogen in a non-porous polymer membrane are different, when the oxygen and the nitrogen are adsorbed on the surface of the polymer membrane, the gas is diffused and passes through the polymer membrane due to the concentration gradient existing on two sides of the membrane, and then the gas is desorbed on the other side of the membrane, because the volume of oxygen molecules is smaller than that of the nitrogen molecules, the diffusion rate of the oxygen in the polymer membrane is larger than that of the nitrogen, so that when air is introduced into one side of the membrane, oxygen-enriched air can be obtained on the other side, and the nitrogen is obtained on the same side. Nitrogen and oxygen-enriched air can be continuously obtained by separating air by a membrane method.

One of the key reasons of the concentration of system oxygen is exactly influenced by the switch on/off, so the no special circumstances of general enterprise frequently carries out the switch on/off, prevents to produce the different condition of concentration, but current equipment need be to filtration at the air pretreatment stage, and air cleaner does not belong to permanent non-maintaining equipment, needs the periodic shutdown to change the maintenance, otherwise influences the quality of oxygen, seriously can lead to rolling up membrane subassembly and scrap.
