Nuclear power steam-jet ship propulsion system

Abstract

The invention discloses a nuclear power steam-jet ship propulsion system, which comprises a ship body, a nuclear reactor, a steam generator, a steam, air and water mixing chamber, a jet nozzle, a jet nozzle controller, a water absorption opening and an air absorption opening; the water outlet of a high pressure heating water tank of the nuclear reactor is communicated with the inlet of a U-shaped pipe at the lower part of the steam generator through a pipeline with a pressure stabilizer; the outlet of the U-shaped pipe is communicated with a water recycling opening of the high pressure heating water tank through a pipeline with a main pump; the air absorption opening is communicated with an air jet annular pipe of the steam, air and water mixing chamber through an air-conveying pipe with an air pump; the water absorption opening is communicated with a water supply opening of the steam generator through a pipeline with a water supply pump and communicated with a steam jet annular pipe of the steam, air and water mixing chamber via the hot steam outlet of the steam generator through a steam-conveying pipe; and the water absorption opening is further communicated with a water jet annular pipe of the steam generator through a water-conveying pipe with a water pump. By adoption of the nuclear power steam-jet ship propulsion system, a ship has high energy utilization rate and long endurance mileage, and has no CO2 pollution.

Description

technical field [0001] The invention relates to a ship propulsion system, in particular to a nuclear power steam jet ship propulsion system. Background technique [0002] Ships are still using the propeller propulsion system. The energy transfer process is as follows: the chemical energy of the fuel is converted into heat energy through combustion, and the heat energy is converted into mechanical energy output through the engine, and then through the transmission to the propeller, which becomes the mechanical energy of the propeller, and the water flow driven by the propeller becomes kinetic energy of water. This kind of propeller propulsion system that uses fuel has the following defects: 1. The propulsion system with this structure has a long energy transmission route, and the efficiency of the engine and propeller is very low, only about 30%, and the power utilization rate is not high. Can't get on; 2. Due to the use of fuel as power, its cruising range is limited; 3. Em...
