The invention relates to the field of liquefied natural gas transportation, in particular to a combined pipe frame punching inerting system for a liquefied natural gas cargo hold, and the system flexibly adjusts gas flow in the hold through staggered distributed combined pipe frame structures and staged aperture and direction design of pipelines. The device is characterized in that a plurality of independent pipelines are designed in a combined mode, the first pipeline obliquely extends downwards to the corner of the cabin bottom, and the second pipeline vertically extends downwards and then obliquely extends upwards to the bottom of the other side; gas introduction spray holes with graded apertures are formed, so that uniform introduction and diffusion of gas are promoted; and through multi-direction hole position layout, rapid flowing and uniform distribution of gas in the cabin are ensured. By means of the system, simultaneous inerting of the whole cabin can be achieved, the gas distribution uniformity is remarkably improved, inerting dead angles are eliminated, and the inerting efficiency is improved.
本发明涉及液化天然气运输领域,尤其涉及一种用于液化天然气货舱的组合管架打孔惰化系统,该系统通过交错分布的组合式管架结构和管道的分阶段孔径及方向设计,灵活调整舱内气体流动。其核心特点包括:多条独立管道的组合设计,第一条管道斜向下延伸至舱底角落,第二条管道垂直向下后斜向上延伸至另一侧底部;设有分级孔径的气体导入喷孔,促进气体的均匀引入和扩散;以及多方向孔位布局,确保气体在舱内的快速流动和均匀分布。通过该系统,可实现全舱同时惰化,显著提高气体分布的均匀性,消除惰化死角,提升惰化效率。
