AI Technical Summary

Technical Problem

Existing carbon dioxide emission systems for underwater vehicles generate noise due to the bursting of carbon dioxide bubbles when released into water, which is problematic for quiet operation.

Method used

A carbon dioxide emission system that includes a carbon dioxide separation device, a gas dissolving device to produce carbonated water, and a carbonated water discharge line to release the carbon dioxide dissolved in water outside the vehicle.

Benefits of technology

Effectively suppresses the generation of air bubbles and associated noise by dissolving carbon dioxide in water before discharge, ensuring quiet operation.

Abstract

To effectively suppress generation of bubbles in water when exhausting carbon dioxide in inboard air of an underwater vehicle into outboard water.SOLUTION: A carbon dioxide discharge system loaded on an underwater vehicle includes: a carbon dioxide separation device for separating carbon dioxide gas from inboard air in the underwater vehicle; a gas dissolution device for dissolving carbon dioxide gas into water and generating carbonated water; a carbon dioxide gas line for supplying the carbon dioxide gas separated by the carbon dioxide separation device to the gas dissolution device; and a carbonated-water discharge line for supplying the carbonated water generated by the gas dissolution device to a discharge port opening to outside of the underwater vehicle.SELECTED DRAWING: Figure 2
