新型船用排气管气密防火通舱装置设计研究

Design and Research on a New Type of Marine Exhaust Pipe Airtight Fireproof Ventilation Device

船舶排气系统是为船舶主机、发电机、燃油锅炉等设备排除工作时产生的废气的管系,除了基本的工作要求外,还应该满足降低噪声的要求。对于一些特殊船舶,还要特别考虑防火防爆问题。由此可见,船舶排气管系的防火对于船舶安全航行、船员的人身安全具有十分重要的作用。一种新型的船用排气管气密防火通舱装置,可以带走主机排气热量,有效降低排温,对于船用排气管的密封性以及防火性起到重要作用。

The ship exhaust system is the pipe system for the exhaust gas generated during the work of the ship's main engine,generator,and oil-fired boiler.In addition to the basic work requirements,it should also meet the requirements of reducing noise.For some special types of ships,special consideration should also be given to fire and explosion prevention issues.It can be seen that the fire prevention of the ship's exhaust pipe system plays a very important role in the safety of ship safety and the personal safety of the crew.A new type of ship exhaust pipe gas-deficient fire-proof cabin can effectively take away the exhaust heat of the host and reduce the temperature discharge,which plays an important role in the sealing of the exhaust pipe and the fire resistance.
