焦化掺混风机密封改造的研究

Study on Rebuild of Mixing Blower Fan Seal on Carbonization

介绍了焦化掺混风机壳体密封由原来简单的迷宫密封改为迷宫密封与气动密封相结合。由于原结构易泄漏且不易维修,改造后彻底解决了漏煤气问题,而且不需经常维修。采用这一技术对原风机密封进行改造具有良好的经济与实际意义。

It introduced that combined labyrinth packing and dynamic seal instead primary simple labyrinth packing of mixing blower fan seal on carbonization. It is easy to spill primary simple labyrinth packing. It is difficult to maintenance. After rebuilding the problem of spilling coal gas is settled and it needn＇t been running maintenance.
