Abstract

The invention discloses a use and storage device and method of waste gas of an underwater vehicle. The use and storage device comprises a liquefied natural gas/liquid hydrogen storage tank pump, a liquid oxygen storage tank, a carbon dioxide storage tank, a cold box, a heat recovery device, a dryer, a mixer, a distributor, a gas-liquid separator, a cooler and a throttle valve; and the liquefied natural gas/liquid hydrogen storage tank pump and the liquid oxygen storage tank are connected with the cold box and the heat recovery device correspondingly, the carbon dioxide storage tank is connected with the mixer through the heat recovery device, the mixer is externally connected with a hot-gas engine, waste gas of the hot-gas engine is connected with the gas-liquid separator through the cooler, the gas-liquid separator is connected with the dryer and the mixer through the distributor correspondingly, the dryer is connected with the cold box, and the cold box is connected with the carbon dioxide storage tank. According to the use and storage device and method of the waste gas of the underwater vehicle, due to the fact that liquefied natural gas/liquid hydrogen and liquid oxygen capableof being stored are used as double energy sources, the cold energy is sufficient, the waste gas discharged by the hot-gas engine is liquefied and stored while fuel and oxygen are supplied for the hot-gas engine, tracks and chemical thermal signals are not left behind, and the engine is not limited and influenced by seawater backpressure.

Description

technical field [0001] The invention relates to an underwater vehicle, in particular to a device and method for using and storing waste gas from the underwater vehicle. Background technique [0002] The exhaust gas (including carbon dioxide, oxygen, water vapor, soot and other components) discharged from the underwater vehicle to the outside of the boat not only leaves track and chemical heat signal, but also is restricted by the back pressure of sea water, reducing the efficiency of the engine. For example, when the exhaust gas is mixed with seawater, it will generate a heat flow slightly higher than the ambient temperature; CO2 reacts with seawater to generate carbonic acid; the exhaust gas is cooled and water is absorbed and discharged overboard, and bubble groups can still be formed; the exhaust gas can form complex wake etc. [0003] Exhaust gas management can be divided into three categories: recirculation, semi-enclosure and total containment. Recirculation means th...
