Double alkali desulfurization precipitator
Double alkali desulfurization precipitator technology is to overcome the limestone - lime method is easy to fouling the development of the shortcomings. The traditional limestone / lime-gypsum flue gas desulfurization process Calcium-based desulfurization agent to absorb sulfur dioxide generated after the calcium sulfite, calcium sulfate, because of its small solubility, easy in the desulfurization tower and pipe formation in the scale, blocking phenomenon The Scaling problems seriously affect the normal operation of the desulfurization system, and even worse seriously affect the normal operation of the boiler system. In order to avoid the use of calcium-based desulfurization agent adverse factors, calcium desulfurization process are mostly equipped with the corresponding mandatory oxidation system (aeration system), thereby increasing the initial investment and operating costs, with cheap desulfurization agent and easy to cause fouling problems , The use of sodium-based desulfurization agent operating costs are too high and the desulfurization products are not easy to deal with, the two contradictory mutual highlights, double alkali flue gas desulfurization process came into being, the process better solve the above contradictions.
