Title:
NITROGEN-OXYGEN MIXTURE GAS MANUFACTURING AND SUPPLYING SYSTEM FOR AIR-SUPPLIED-TYPE DIVING
Document Type and Number:
Japanese Patent JP2002068081
Kind Code:
A
Abstract:

To provide a compact nitrogen-oxygen mixture gas manufacturing and supplying system for air-supplied-type diving capable of saving a space, and consistently and continuously manufacturing the oxygen high partial pressure nitrogen-oxygen mixture gas of the desired oxygen concentration from the air at a diving site to supply the gas to a diver.

This system comprises a compressor 2 for supplying the air, a first air storage tank 6 for storing the air from the compressor 2, a membrane filter 7 connected to the first air storage tank 6 and separating nitrogen in the air supplied from the first air storage tank 6 to manufacture the nitrogen- oxygen mixture gas of high oxygen partial pressure, a means 14 for adjusting the concentration of oxygen by increasing and decreasing the amount of nitrogen separated and released by the membrane filter 7, an air-sending compressor 3 connected to the membrane filter 7, sucking the manufactured nitrogen-oxygen mixture gas and raising its pressure, and a second air storage tank 8 connected to the air-sending compressor and supplying the pressure-raised nitrogen-oxygen mixture gas to the dive while storing the nitrogen-oxygen mixture gas.
