SHIP CARGO HOLD VENTILATION METHOD AND VENTILATION SYSTEM

摘要

A ship cargo hold ventilation method and a ventilation system, the method comprising: step S10, installing fans; step S20, determining ventilation state according to the operating state of a ship, and, in a sailing state, taking in air from the bow to an upper cargo hold and a lower cargo hold, and discharging air from the stern; in a loading state, taking in air from the bow and stern to the upper cargo hold, and discharging air from midship, while taking in air from a loading end to the lower cargo hold, and discharging air from an opposite end; the system is provided with multiple ventilation ducts corresponding to various reversible rotating fans, silencing baffle plates being disposed below the reversible rotating fans, and a sound insulation material (5) being laid on inner walls of the ventilation ducts; upper and lower cargo holds may be ventilated by means of controlling the reversible rotating fans in the the upper and lower cargo holds to employ different manners of operation according to the different operating states of the ship; meanwhile, the configuration of the silencing baffle plates and sound insulation material (5) may reduce noise pollution within the cargo holds.
