The sliming water closed circuit practice of Chensilou coal process plant;
陈四楼选煤厂煤泥水实现闭路循环的实践
In order to save water and reduce polluted water discharge,we use elliptical tube in rectangular steel fin tube which is treated in hot dipping zinc and use force cooling by blast axial flow fan to condensate the air in tube then return the condensate to boiler to form a closed circuit,thus replace conventional water cooling tower.
采用椭圆管穿矩形钢翅片经热浸锌后组装的冷凝翅片管束,用鼓风式轴流风机强制将乏汽在管内冷凝成水返回锅炉形成闭路循环使用,从而可以取代常规开放式水冷却塔,极大地节约汽轮机运行的耗水量和污水排放量,对环境保护起到了积极的作用。
Simplified process of slime water treatment employed at Chengzhuang Coal Preparation Plant in that all slime water was collectively treated;the particulate content in washwater was then reduce down to 10g/L by reasonable flocculent addition;realized were the automatic balance and closed circuitry of wash water.
成庄选煤厂采用简化后的煤泥水处理工艺,将全厂煤泥水集中处理;合理添加絮凝剂,使洗水浓度降至10g/L以下;利用连通器原理,实现洗水自动平衡等措施,实现选煤厂洗水闭路循环。
Scaling mechanism of closed circulation of ash sluicing water in ash sluicing;
海水与淡水冲灰系统灰水闭路循环结垢机理
Internally it achieves the closed circulation of the gas, water and waste heat and comprehensive reutilization of the solid waste and externally, Qinggang successfully disposed the hazardous waste of chrome slag from the chemical industry.
在内部,实现了煤气、水、余热、固体废物的闭路循环和综合利用,在外部,资源化处理化工危险废物-铬渣,初步建立了区域循环产业链条,实现了经济、环境、社会和谐发展。
The adoption reduces slime water concentration, enables the closed circulation and increases product quality.
针对富强选煤厂煤泥水治理难的问题,采用聚合铝作为凝聚剂,降低了洗水浓度,实现洗水闭路循环,提高了产品质量。
