Underwater thermoelectric hybrid power system based on steam plasma

Abstract

The invention discloses an underwater thermoelectric hybrid power system based on steam plasma. The underwater thermoelectric hybrid power system comprises a combustion chamber, a gas-solid separator,a turbine, a heat exchanger, a condenser, a gas-liquid separator, a second compressor, a fuel cell, a powder supplying device, a plasma igniter / booster, a first compressor and a pump. An aluminum / water combustion reaction is started and enhanced through the plasma igniter / booster by taking aluminum powder as fuel and taking primary superheated steam as an oxidizing agent. On one hand, water is heated through great heat released by the aluminum / water reaction to be changed into steam and drive the turbine to do work to generate thrust; and on the other hand, hydrogen generated through the aluminum / water reaction is converted into electric energy for driving the plasma igniter / booster through the fuel cell, therefore, efficient utilization of energy is achieved, and the disposal problem ofhydrogen in an underwater environment is reasonably solved.

Description

technical field [0001] The invention relates to a propulsion system for surface ships and underwater vehicles, in particular to a thermoelectric hybrid power system suitable for underwater environments. Background technique [0002] The underwater unmanned vehicle (UUV) is a kind of smart weaponry with long endurance and recyclable capability. It has many advantages such as wide combat use, high intelligence, strong maneuverability, good stealth performance, flexible use, various shapes and deployment forms, and repeated use. [0003] At present, the UUV power system is mainly driven by batteries, mainly zinc / silver batteries, lithium-ion batteries, etc., but the existing batteries have low energy density and cannot meet the requirements of long battery life and long range of UUV. [0004] However, the cost of fuel cells is generally high, and the reaction / startup performance is poor, so it is difficult to apply to the underwater environment. Table 1 shows the theoretical ...
