一体化净水器在锅炉冲渣冲灰水处理中的应用

The application of integrated water clarifier on treatment of water flushing cinder-dust of boiler

锅炉冲渣冲灰水的悬浮物高达3000mg/L,原有处理工艺造成平流沉淀池出水悬浮物仍然高达1000mg/L,因此在平流沉淀池出水加压送入一体化净水器进一步的处理,出水悬浮物降到10mg/L以下,净化后的废水主要回用于锅炉烟气水膜除尘器及冲渣冲灰,废水零排放;闭路循环;回收冲渣冲灰水达到100%,去除悬浮物大于99%以上。

The suspended matter in water flushing cinder and dust of boiler was up to 3000mg/L, that in effluent water of a fluent - flow sedimentation tank was still up to 1000mg/L as old treating process. As the effluent wa- ter of a fluent - flow sedimentation tank was further treated by compressed into a integrated water clarifier, so that suspended matter in effluent water decreased to less than 10mg/L. The clarified waste water could re - use to be water dust scrubber for boiler exhaust gas and to flush cinder and dust, waste water was zero released and closed - circult, recovery of water flushing cinder and dust was 100%, dislodged suspended matter was more than 99%.
