HBF—S 120/10型加压过滤机在田庄选煤厂的应用

Application at Tianzhuang Coal Preparation Plant of the HBF-S120/10 Hyperbaric Filter

田庄选煤厂利用HBF—S 1 2 0 1 0型加压过滤机代替PG— 1 1 6 1 2型真空过滤机解决了浮选精煤脱水问题 ,浮选精煤滤饼含水 1 6 5 %左右 ,滤液质量浓度小于 3 0g L ,操作管理方便 ,设备故障率低 ,为选煤厂能带来较好的经济效益和社会效益 ;对应用中存在的问题也已采取或正在探索有效的解决方法。

The difficulty from de watering of flotation concentrate at Tianzhuang Coal Preparation Plant was solved by substitution of the original PG 118/12 vacuum filter by HBF S120/10 hyperbaric filter. The moisture content of filtered cake was as low as 16.5% and the solid content of filtrate was as low as 3.0 g/L; attained were also easier operation, lower breakdown and higher economic and social benefits. Effective counter measures against the problems arisen from its operation are under consideration.
