Modularized ventilation tower structure of cargo hold of chemical tanker and installation method of modularized ventilation tower structure

The invention discloses a modularized ventilation tower structure of a cargo hold of a chemical tanker and an installation method of the modularized ventilation tower structure. A multi-specialty and multi-type-of-work composite modular unit is combined with a step bridge platform, a foam gun platform, a canopy, a cable transition box, a cable bracket, a lamp bracket and the like, the structural and system integrity is greatly improved, the pre-outfitting rate of a ship is greatly improved, the construction difficulty and workload on the ship in the later period can be greatly reduced, the shipbuilding period is shortened, and the construction cost is reduced. And the construction cost is reduced. 本发明公开了一种化学品船货舱的模块化透气塔结构及其安装方法，本发明将由透气管、油气回收管、及其相关系统管路和操作平台组成的透气塔，与步桥平台、泡沫炮平台、遮雨棚、电缆过渡箱、电缆托架、灯架等组合成一个多专业、多工种的复合型模块化单元，结构和系统完整性大大提高，大大提高了船舶的预舾装率，可大大降低后期船上的施工难度和工作量，减少了造船周期，降低了施工成本。
