Abstract

PURPOSE:An equipment system in which high-pressure air is dissolved in perfluorocarbon in a pressure tank and the fluorocarbon is sprayed in the gas-liquid separation tank to release the air, thus enabling easy and continuous mass-production of oxygen-enriched air. CONSTITUTION:Perfluorocarbon 2 is charged in the pressure tank 1 so that an adequate space 3 is left and air is sent from the compressor 4 through the diffusion pipe 6 therein. The pressure of the tank 1 is adjusted to 4-10 atmospheric pressure by means of the pressure controller 8 to effect absorption of a large amount of oxygen into the perfluorocarbon which has high affinity to oxygen together with air. Then, the perfluorocarbon containing air dissolved 2 is jetted through the jetting nozzle 12 into the gas-liquid separation tank 11 which is kept at normal pressure to release oxygen-enriched air. The perfluorocarbon stored in the tank over a certain level is detected with the level sensor 17 and pumped to the pressure tank 1. As the above perfluorocarbon, C6F14, C9F20, (C4F9)3N, C8F18, C8F16O, is suitably used.

In general, the higher the amount of oxygen per unit volume of air supplied to the burner of combustion equipment that requires high temperatures, such as melting glass, forging steel materials, and firing ceramics, the better the combustion efficiency. For this reason, in the past, oxygen gas from oxygen cylinders or liquid oxygen was supplied to the air. However, since such oxygen has a surface value, it is not preferable to use them. In addition, in recent years, in order to increase the oxygen content in the air, that is, to obtain oxygen-enriched air, a polymer membrane is used and air is permeated through the polymer membrane, which increases the oxygen concentration in the atmosphere. It has been proposed to concentrate 21% by volume to 23-31% by volume, and there is interest. As the polymer membrane mentioned above, silicone polymer membranes are beginning to be put into practical use. However, in this method, atmospheric air is permeated through a polymer membrane, so it is difficult to obtain a large amount of oxygen-enriched air at once. The disadvantage is that it requires quite large-scale equipment.

従って本i明は上記高分子膜を使用せず番こ、酸素富化

Therefore, the object of the present invention is to provide an apparatus for obtaining oxygen-enriched air without using the above-mentioned polymer membrane.

Generally, the amount of dissolved air increases as the pressure increases,
Among the main air constituents, nitrogen, oxygen, and hydrogen, oxygen dissolves best in perfluorocarbon, and the content of the oxygen component in the dissolved air is as shown in Figure 2. For example, the oxygen content in the atmosphere is about 21% by volume, but in perfluorocarbons under pressure there are some differences depending on the type of perfluorocarbon, but at about 4 atmospheres the oxygen content in dissolved air is (Concentration) is approximately 27% by volume
It becomes about 29% by volume at 10 atmospheres, and after that, even if the pressure is increased, the oxygen content does not increase much.

Therefore, by utilizing the above-mentioned solubility characteristics of air and the oxygen contained therein in perfluorocarbon, if air is introduced into perfluorocarbon under pressure and the air is dissolved, oxygen content of up to 30% by volume can be achieved. When the pressurized air-dissolved perfluorocarbon is returned to atmospheric pressure (1 atm), the air dissolved in the perfluorocarbon is released from the perfluorocarbon. The oxygen component in the air released at this time will have a high content of up to about 29% by volume if the pressure is 10 atmospheres or more during dissolution.
