摘要
韶钢 1999年建成的POC型干式煤气柜是国内首次采用的圆柱形稀油密封柜 ,与国内常用的曼形煤气柜相比 ,其活塞运行更加平稳 ,贮存煤气压力较曼形柜高 1.5～ 2kPa ,建柜所需钢材减少 2 0 % ,运行费用减少约 10万元 /年 .但在实际运行中发现该柜存在立柱安装精度不够 ,侧板对接焊缝、侧板外部与立柱焊缝与活塞倾斜检测装置读数困难等问题 .针对上述问题提出了一些具体的解决办法 ,有效地保证了干式煤气柜的正常运行 。
The POC type dry_gas holder built in 1999 in SISG is the first cylindrical thin_oil- sealed gas holder in China. In comparison with the widely used MAN type gas_holder, the POC type's piston runs more smoothly, its reserve pressure is 1.5～2.0KPa higher, steels needed to build it is reduced by 20 pre cent, and its operating cost is cut down by 100?000$/a. However, a number of problems exist with the holder structure, such as the insufficient installation precision of the anchor columns, the poor quality of the butt welds in the side boards, as well as of the welds between the side board and the anchor column, and the difficulties with taking readings on the piston alignment indicator. Measures have therefore been proposed to get ride of these problems. As a result, a normal operation of the holder is ensured, and remarkable economic and social benefits obtained.
