Maintenance Construction Technology of 30000 m3 Low Pressure Wet Helical Gas-Holder

30000m3低压湿式螺旋储气柜是管道煤气储配系统中的一个大型设备,主要用于储存气源,在用气高峰时及时对输送管道中的燃气进行补给,达到调峰作用,以确保用户正常用气。湖南娄底市新华联燃气有限公司30000m3低压湿式螺旋储气柜,在储气过程上升至钟罩(Ⅰ塔)时,由于加压机房罗茨风机的突然故障,导致钟罩导轨脱离导轮座,近10°倾角侧翻。30000m3储气柜净重达452t,工作量较大,维修施工难度也较大。只有认真仔细研究现场实际情况和编制好维修施工方案,才能达到安全快速维修的目的。

30000 m3 low pressure wet helical gas--holder is a large--scale equipment of pipeline gas storage and distribution system, which is mainly used for primary storage of gas source and provides gas supply promptly in the peak hours of gas consumption to ensure normal operation. 30000 m3 low pressure wet helical gas--holder provided by Hualian gas Co. Ltd. of Loudi, Hunan malfunctions due to bell nearly 10° inclination rollover, which is caused by sudden failure of the press railing urized from the guide wheel seat engine room roots blower. The maintenance construction is of great difficulty as the gas holder with net weight of 452 tons. Safe and fast maintenance purposes could be achieved only with careful study of the actual situation at the scene and well-- planned the maintenance construction program.
