Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] figure 1 It is a schematic diagram of the overall structure of the pressurized chamber system used for oxygen circulation.

[0022] Such as figure 1 As shown, the pressurized cabin system for oxygen circulation in this embodiment includes: a pressurized cabin body 100, an oxygen supply device 200 outside the cabin, an oxygen supply device 300 in the cabin, an oxygen recovery device 400, and an air supply device 500 and smart controllers. The oxygen supply device 200 outside the cabin delivers oxygen to the oxygen supply device 300 in the pressurized cabin body 100, and the oxygen discharged from the oxygen supply device 300 in the cabin is recovered by the oxygen recovery device 400 and can be supplied to the cabin again. The oxygen device 300 supplies oxygen and can be used for oxygen filling. The air supply device 500 supplies air ...

Abstract

The invention provided a pressurized cabin system for oxygen circulation. The pressurized cabin system includes a pressurized cabin body, an out-cabin oxygen supply device, an in-cabin oxygen supply device and a discharged-oxygen recycling device; the out-cabin oxygen supply device is used for transporting oxygen to the in-cabin oxygen supply device inside the pressurized cabin body, and after theoxygen discharged by the in-cabin oxygen supply device is recycled by the discharged-oxygen recycling device, the oxygen is supplied to the in-cabin oxygen supply device. The pressurized cabin systemhas the advantages that the used oxygen is recycled and enters the oxygen supply device again when needed, and the oxygen utilization rate can be greatly and effectively increased regarding in-cabinoxygen supply; the oxygen supply amount is reduced; consumed oxygen is effectively reduced.

Description

technical field [0001] The invention relates to a pressurized cabin system for oxygen circulation, which is especially suitable for the pressurization cabin system for oxygen circulation used on offshore platforms. Background technique [0002] When working underwater, the partial pressure of various gases in the alveoli increases with the increase of water pressure, and immediately balances with the partial pressure of various gases in the inhaled compressed air. Because the gas partial pressure in the alveoli is higher than the gas pressure in the blood, the gas will correspondingly increase the amount of gas dissolved in the blood according to Boyle's law. When the human body gradually changes from a high-pressure environment to a normal pressure environment, the gas in the blood penetrates through the blood vessel wall of the pulmonary artery to the lungs, and is gradually and slowly discharged from the body through the alveoli without adverse consequences. When the dec...
