3、工艺设计方案Process design scheme

3.1、生产方法、规模及产品性能Production method, scale, and product performance

3.1.1工厂生产方法：本项目采用天然气作为燃料，采用带竖式预热器、竖式冷却器的回转窑煅烧系统生产线。Plant production method: the project uses natural gas as the fuel, and adopts the rotary kiln calcining system production line with vertical preheater and vertical cooler.
3.1.2工厂建设规模：见表 3.1Plant construction scale: see Table 3.1
表 3.1 工厂建设规模及产能
Table 3.1 Plant construction scale and production capacity

（1）年工作时间：330 天Annual working hours: 330 days
（2）单位产品热耗Thermal consumption per unit product：石灰lime≤1200kCal/kg  ，单位产品石灰石料耗Limestone material consumption per unit product：≈1.78kg/kg 石灰lime
（4）产品粒度组成：活性石灰约块灰 Block lime 80%、粉灰 pulverized lime  20%。
（5） 除尘有组织排放含尘浓度指标
Dust content concentration index of dust removal：＜10mg/Nm³
3.1.3物料运输方式：石灰石由汽车运输至原料储存库，天燃气运输到厂区外红线一米处；成品通过成品库散装装车后汽车输送给各用点。Material transportation mode: limestone is transported from the truck to the raw material storage warehouse, natural gas to the red line outside the factory; the finished product is transported to the use points after bulk loading through the finished product warehouse.
