Emergency Ventilation System of Ship Using Fire Main Line Pressure

摘要

The present invention relates to an emergency ventilation device for a ship, which comprises a water turbine motor having a ventilation fan as an emergency ventilation device for a ship using main digestion pressure, wherein the water turbine motor has a pressure of seawater supplied from a main digestion pipe And a seawater supply line for supplying seawater to the water turbine motor is provided with a fire hydrant and a ventilation operation valve and a drain for supplying or blocking seawater by a water turbine motor. According to the emergency ventilation system of the ship using the fire main pressure according to the embodiment of the present invention, when the electric fan can not be used due to the power failure or emergency ventilation is required due to the fire of the ship, Efficient and stable ventilation of the compartment requiring emergency ventilation by allowing water turbine motors and ventilation fans to operate using the seawater pressure of the main digestion main even in the powerless state without power supply by simple operation of supplying the seawater to the water turbine motor To perform the function.
