RESEARCH ON THE DETERIORATION PROBLEM OF CLARIFIED WATER IN COAL GASIFICATION PLANT AND ITS RECTIFICATION MEASURES
This article studied the problem of high suspended solids in the clarified water of the SE gasification device,which seriously affects the long-term operation of the gasifier.The causes of the problems were analyzed from the aspects of dispersant addition position,flocculants addition amount,clarification tank operation,and vacuum filter operation.Targeted measures were formulated to modify the dispersant addition position to avoid dispersant addition to the clarification tank,optimize flocculants addition amount,clean the overflow weir of the clarification tank to prevent short circuit of clarified water,optimize the operation of the vacuum filter to prevent slag accumulation in the clarification tank from affecting the quality of clarified water,and the system was restored to normal.
