我厂现有2座8t纯氧顶吹转炉,炼钢烟尘净化采用“二文一塔”湿法除尘系统,除尘污水经过澄清、冷却后闭路循环使用,沉淀池底部的污泥浆用砂浆泵输送到污泥处理间,经真空过滤脱水后含湿率约30％的污泥,过去是直接用汽车送至厂外堆放,这不仅污染了环境,而且又占用农田,为此厂方每年还要补贴农民的土地占用费。按我厂年产20万吨钢计,每年将产生4000吨干污泥外运堆放。为了利用转炉除尘污泥、结合我厂实际 I plant the existing two 8t pure oxygen top-blown converter, steelmaking dust purification using “a text of a” wet dust removal system, the dust after the clarification of the sewage, cooling closed-loop use, the bottom of the sedimentation tank sludge slurry pump Transported to the sludge treatment room, the vacuum filtered dehydration after the moisture content of about 30% of the sludge in the past is used directly to the factory outside the park, which not only pollute the environment, but also occupy the farmland, for which the factory every year To subsidize the farmers land occupation fee. According to our plant annual output of 200,000 tons of steel, each year will produce 4,000 tons of dry sludge shipped stacked. In order to use the converter dust sludge, combined with the actual plant
