随着碱性氧气转炉炉容的增加和吹氧率的提高,所产生的转炉煤气量增加,同时,因能源费用的飞涨,回收转炉煤气的工作变得越来越重要。 转炉煤气的产生主要是在吹炼阶段。为此,近年来,德国曼内斯曼—德马克公司在开发用于收集高质量转炉煤气的设备方面作了许多工作,所开发的设备主要是抑制煤气二次燃烧装置和气流切换装置。 气流切换装置是根据转炉煤气中CO的含量将煤气输送至燃烧排放管道或储气罐内。 该置的核心部件是气体分流器,它通过压力控制阀,旁路阀和储气罐口的水封调节装置进行分流操
With the increase of basic oxygen converter furnace capacity and oxygen blowing rate, the amount of converter gas produced increases. At the same time, the recovery of converter gas becomes more and more important due to the soaring energy costs. Converter gas production is mainly in the blowing stage. For this reason, in recent years, Mannesmann-Demark, Germany, has done a lot to develop equipment for collecting high-quality converter gas. The equipment developed has been mainly the suppression of gas secondary combustion and air flow switching devices. Air flow switching device is based on the content of CO in the converter gas to the gas delivery to the combustion exhaust pipe or gas tank. The heart of the unit is the gas diverter, which shunts through the pressure control valve, the bypass valve, and the water seal adjuster for the reservoir port
