随着国家对环境保护要求的日益严格,现有和新建燃煤含硫量大于1%的电厂必须建设脱硫设施[1]。电厂脱硫工艺主要以石灰石/石灰—石膏湿法工艺为主,约占总容量的86%。湿式制粉设备为湿式球磨机,干式制粉设备为立式辊磨机(简称立磨)。立磨为料床粉磨,与球磨机相比具有入磨粒度大、粉磨效率高、单位电耗低及节能环保等优点,
With the increasingly stringent environmental protection requirements of the state, existing and new coal-fired power plants with a sulfur content of more than 1% must construct desulfurization facilities [1]. Power plant desulfurization process mainly limestone / lime - gypsum wet process-based, accounting for about 86% of the total capacity. Wet milling equipment for wet ball mill, dry milling equipment for vertical roller mill (referred to as vertical mill). Vertical mill for the material bed grinding, compared with the ball mill into the grinding particle size, grinding efficiency, low power consumption and energy saving and environmental protection, etc.,
