Evaporation gas treatment system for fuel cabin of dual-fuel ship

According to the evaporation gas treatment system for the fuel cabin of the dual-fuel ship, the fuel cabin is connected with a dual-fuel boiler through an evaporator electric heater, and the dual-fuel boiler is sequentially connected with an atmospheric condenser, a hot well and a boiler feed pump through pipelines and then returns to the dual-fuel boiler. The evaporator electric heater is located in the fuel cabin pipeline interface room, and the dual-fuel boiler, the atmospheric condenser, the hot well, the boiler feed pump and the atmospheric condenser sea water pump are located in the cabin. A related equipment power supply is supplied to the ship emergency generator, so that the energy consumption is low during working, the total energy consumption of the fuel cabin boil-off gas treatment system is improved, and the economical efficiency is high. The ship and other devices of the gas supply system are not arranged in the same room, the boil-off gas is not heated through the devices of the gas supply syst
