JPS60103005A - Manufacture of o2-enriched air - Google Patents

Abstract

PURPOSE:To obtain O2-enriched air having higher oxygen concn. than the air at the earth's surface part by performing a deaeration treatment for running water containing dissolved air in large quantities and by collecting the bubbles floated up on the liquid level. CONSTITUTION:It is utilized that the ratio of nitrogen to oxygen is about 4/1 in the atmosphere and about 2/1 in the state that the air is dissolved in water. Namely, a deaeration treatment (for example, installation of a collision plate, a stirring, an electromagnetic operation and a vacuum operation) is performed for running water containing dissolved air in large quantities (for example, an ocean current, a river current and a flow from a reservoir for pumping-up electric power station) to float up the dissolved air as the bubbles. After the bubbles are collected in a vessel installed near the water level, they are further sealed in a tank by using a pump to obtain O2-enriched air.

Description

DETAILED DESCRIPTION OF THE INVENTION The nitrogen to element ratio in the atmosphere is 4:1, but in water it is close to 2:1.

Therefore, large amounts of dissolved air flow in a certain direction (ocean currents, tidal currents,
If a demolding treatment is applied to the flow of rivers, lakes, pumped storage power generation batteries, etc., some of the eroded air will float to the surface, and this will be trapped as air bubbles on the water surface or above the air installed in the water, and then pumped. can be sealed in a tank to create oxygen-enriched air with a higher oxygen concentration than surface air. Examples of single or simultaneous demolition treatment methods include the installation of collision plates, baffle plates, drift plates, parallel plates, wire mesh, perforated plates, tubular bodies, spiral materials, granular materials, and filtration media.

These include mechanical stirring or vibration, heating operations, microwave currents or radio waves, high-frequency currents or radio waves, ultrasonic waves, laser beams, electrophoresis, electrolysis, electromagnetic operations such as static electricity, and decompression operations.

Note that this is a case where a certain amount of hydrogen is found to be mixed in with electrolysis.

Since the bubbles generated in the present invention induce other bubbles one after another, the effect of depth cannot be ignored. Further, even if the amount generated per unit area is small, it can be easily implemented over a large area to produce a large amount of oxygen-loaded air.

The present invention is similar to JP-A-50-80993.81988 in terms of concentrating oxygen using dissolved air, but pressurization and
By avoiding mechanical operations such as depressurization and constantly using fresh running water, the preparation of raw materials is made more precise. Furthermore, the wood invention avoids the method of Japanese Patent Publication No. 4822596 and 50-2715, which uses a membrane in water to highly concentrate oxygen, so it can produce oxygen-enriched air roughly 20 to 40%. suitable for.

Used running water with reduced dissolved oxygen will naturally recover by taking in oxygen from the atmosphere, but if you are concerned about this, you can use the same natural forces to promote air dissolution to the water surface using known means. good.

From the standpoint of environmental protection, it is natural to surround the container with silk as appropriate to allow the fish to move around while the dissolved air is being introduced into the container.

The energy irradiation of the present invention has a synergistic effect in the case of rapid flow, and is considered to be a method of producing oxygen-enriched air at a cost lower than liquid air separation methods or adsorption-desorption methods.
