REMOVAL OF SCALE FOR INTERMITTENT WASHING SMOKE DISCHARGE APPARATUS IN FLUE GAS DESULFURIZING APPARATUS

摘要

PURPOSE: To efficiently prevent the formation of scale and deposit by coating the surfaces of mist eliminators in wet process scrubber flue gas desulfurization systems with a thin coating of talc. CONSTITUTION: The surfaces of the wet process scrubber flue gas desulfurization systems to carry out intermittent washing cycles are coated with a thin coating of talc. At this time, the talc consists of magnesium silicate as a base material. A water-soluble thickener, such as wear-soluble polymer of ethylene oxide, and a scale preventing agent, such as acrylic polymer or phosponate, are mixed and suspended with the talc and the surfaces are coated with this suspension by spraying, etc., in such a manner that the coating is formed to be 0.1 to 2 mm.
