塔体设计： 脱硫塔上主要的人孔、安装孔管道孔：除雾器安装孔，每级至少一个；喷淋浆液管道安装孔，至少一个；脱硫塔底部清渣孔，至少一个；烟气入口烟道设置一人孔，以便大修时清理烟道可能的积垢。 脱硫塔上主要的管孔：循环泵浆液管道入口，一般为3个；液位计接口，一般为2～3个，石膏浆液排出口1～2个；排污口1个；溢流口1个；滤液返回口1个；事故罐浆液返回口1个；地坑浆液返回1个；搅拌机接口2～6个；差压计接口2～4个。 储液区：一般塔底液面高度h1=6m～15m； 喷淋区：最低喷淋层距入口顶端高度h2＝1.2～4m；最高喷淋层距入口顶端高度h3≥vt，v为空塔速度，m/s，t为时间，s，一般取t≥1.0s；喷淋层之间的间距h4≥1.5～2.5m； 除雾区：除雾器离最近（最高层）喷淋层距离应≥1.2m，当最高层喷淋层采用双向喷嘴时，该距离应≥3m；除雾器离塔出口烟道下沿距离应≥1m. The design of the tower body: desulfurization tower main manhole, pipeline installation hole hole: demister mounting holes, each at least one mounting hole; spray slurry pipeline, at least one; at the bottom of the desulfurizing tower slag hole, at least one flue gas entrance flue is arranged; a manhole, clean smoke may scale to overhaul when. The main pipe hole desulfurization tower: the slurry pumps entrance, generally 3; level gauge interface, generally 2 ~ 3, gypsum slurry outlet 1 ~ 2; 1 sewage outfall; an overflow port 1; filtrate return port 1; slurry return mouth 1 accident tank pit; the slurry return 1; mixer interface 2 ~ 6; 2 ~ 4 meter interface. The liquid storage area at the bottom of the tower: h1=6m ~ 15m liquid level; spray zone: minimum spray layer from the top entrance height h2 = 1.2 ~ 4m; the highest spray layer from the entrance top height is greater than or equal to vt H3, V m/s, t empty tower velocity, time, s, general t is larger than or equal to 1.0s; the spray layer between spacing of H4 = 1.5 ~ 2.5m; mist eliminator from the nearest area: (top) spray layer distance should be greater than or equal to 1.2m, when the top layer adopts two-way spray nozzle, the distance should be greater than or equal to 3m; demister from tower outlet flue along the distance should be greater than or equal to 1m
