Equipment and process for switchable production of white cement clinker and Portland cement clinker
The invention belongs to the field of cement firing processes and equipment, and particularly relates to equipment and a process for switchable production of white cement clinker and Portland cement clinker. Low-temperature secondary and tertiary air pipelines are adopted when the white cement clinker is produced, secondary and tertiary air is provided for fuel combustion of a rotary kiln and a decomposing furnace, and when the Portland cement clinker is produced, a high-temperature secondary air pipeline and a high-temperature tertiary air pipeline are switched to provide high-temperature secondary air and high-temperature tertiary air for fuel combustion of the rotary kiln and the decomposing furnace, or the high-temperature tertiary air pipeline is adopted to provide high-temperature tertiary air for fuel combustion of the decomposing furnace, secondary air enters the rotary kiln through a single-cylinder bleaching machine, and residual air is exhausted into a waste gas treatment system through a residual air pipeline. The equipment and the process for switchable production of the white cement clinker and the Portland cement clinker are provided to solve the problem that production processes of the white cement clinker and the Portland cement clinker cannot be switched and compatible, and manufacturers can flexibly select to produce the white cement clinker and the Portlandcement clinker by adopting the equipment and the process for switchable production of the white cement clinker and the Portland cement clinker according to market demands.
本发明属于水泥烧成工艺及设备领域，尤其涉及一种可切换生产白水泥熟料及硅酸盐水泥熟料的设备及工艺，生产白水泥熟料时采用低温二、三次风管道，为回转窑和分解炉燃料燃烧提供二、三次风，生产硅酸盐水泥熟料时，切换为高温二、三次风管道，为回转窑和分解炉燃料燃烧提供高温二、三次风，或者采用高温三次风管道，为分解炉燃料燃烧提供高温三次风，二次风通过单筒漂白机进入回转窑内，余风通过余风管道排入废气处理系统。本发明提供一种解决白水泥熟料与硅酸盐水泥熟料生产工艺不可切换兼容的问题，生产厂家可根据市场需求，采用可切换生产白水泥熟料及硅酸盐水泥熟料的设备及工艺，灵活选择生产白水泥熟料与硅酸盐水泥熟料。
