SUBMERSIBLE-CRAFT POWER PLANT Russian patent published in 2004 - IPC

FIELD: power supplies for submersible craft. SUBSTANCE: proposed power plant has electrochemical generator incorporating oxygen supply line connected to oxygen storage unit; hydrogen supply line; and water drain line connected to water accumulation tank. Newly introduced in power plant are gas-cushion aluminum storage tank and reactor installed in bottom part of tank; alkali solution mixing and feeding unit; concentrated alkali storage tank with inlet and outlet pipe unions; hydrogen outlet line communicating with gas cushion of aluminum storage tank and hydrogen feeding line; alkali solution feeding line communicating with reactor inlet and alkali solution mixing and feeding unit outlet; reaction products outlet line communicating with reactor outlet and with concentrated alkali storage tank inlet; concentrated alkali feeding line communicating with concentrated alkali storage tank outlet and with alkali solution mixing and feeding unit inlet; as well as water feeding line communicating with water accumulating tank outlet and with second inlet of alkali solution mixing and feeding unit; installed in tandem in hydrogen outlet line are hydrogen pressure transducer, adjustable hydrogen feed valve, hydrogen moisture separator, and hydrogen pressure reducer; installed in alkali solution feeding line are alkali solution concentration sensor and adjustable alkali solution feed valve; installed in tandem in reaction products outlet line are reaction products outlet valve, heat-transfer apparatus for cooling reaction products, and adjustable reaction products inlet valve; installed in tandem in water supply line are adjustable pump and adjustable water feed valve; installed in tandem in concentrated alkali supply line are adjustable concentrated alkali feed valve and alkali concentration sensor; hydrogen moisture separator communicates through water accumulating line with second inlet of water accumulating tank. EFFECT: enhanced reliability and fire safety, reduced cost of hydrogen production thereby enhancing safety and reducing cost and start-up time of power plant. 1 cl, 1 dwg
