Reason Analysis for Smoke Watered of Pocked-stone Water-film Dust Collector and its Improvement

The reasons for smoke watered of the pocked-stone water-film dust collector, such as unwatered in the overflow channel, normal water-film can’t be formed in internal cylinder, the smoke entrainment in upper water curtain and air leakage, etc. Thus case ash deposit on fan impeller of the induce draft fans, corrosion and vibration. Feasible improvement measures are put forward and eliminate a great part of smoke watered. The practical use shows that the improvement is good, having very good economic and popularized value.
