Description

[0001] The present invention relates to a membrane-type membrane apparatus for artificial gills,

The present invention relates to a modular membrane device for artificial agar, and more particularly, it relates to a membrane module for artificial agar using a device for separating dissolved oxygen in water and using the membrane for human breathing and performing infinite underwater operation without oxygen supply equipment such as an oxygen tank To a modular membrane device for artificial agar.

In general, the underwater breathing apparatus used for underwater activities usually uses a breathing tube such as an oxygen tank or a snorkel in which air is compressed.

Here, the breathing apparatus using the oxygen tank is a method in which the user breathed the compressed air when breathing, and discharges the carbon dioxide into the water while breathing. However, since the respiratory apparatus using the oxygen tank includes not only the oxygen tank but also the regulator, the pressure gauge, and the like, it is expensive and the time of the water operation is limited according to the storage capacity of the air. In addition, it is inconvenient to move due to the weight of the equipment, and the process of charging oxygen before use must be preceded. In this process, there is a risk of explosion due to carelessness, .

In addition, the snorkel breathing apparatus is composed of a hose through which air is exposed on the water surface and a mouthpiece which supplies air through the mouth portion of the user, and has the advantage of being able to perform underwater activities for a long time. However, There is a disadvantage in that it is difficult to deeply submerged, and there is a problem that water is inflowed through the hose exposed on the water surface, and breathing becomes difficult.

In addition, there is an artificial gill in the underwater breathing apparatus, which is a portable device that allows human to breathe by separating the oxygen present in the water. The core technology of this device is the dissolved oxygen separation technology in the water. Conventionally developed artificial gill technology uses centrifugal separation method developed in Israel, but it has a disadvantage in that the structure of the centrifugal separator is complicated because the fluid must be rotated at a high speed.

At Waseda University in Japan, we have developed an oxygen separation system using a hollow fiber and two loops using hemoglobin as an oxygen carrier. However, since it is necessary to include two loops, it is difficult to downsize it as a portable type.

In addition, basic research is being carried out in the United States, but the development of artificial gill is still a moot point.

In addition, there is a system for generating oxygen using an electrolysis method in a submarine or the like as a non-portable oxygen generating device. However, since a large amount of electricity is consumed, it is difficult to develop a small- A battery or a power generation device is required.

A related art related to this is disclosed in Korean Patent No. 10-1131195 entitled " pressurized hollow fiber membrane underwater breathing apparatus ".
