Abstract

The present invention relates to a desulfurization synergist having a scale inhibition performance and for a limestone-gypsum wet flue gas desulfurization system (FDG), and a preparation method thereof. The desulfurization synergist is characterized in that the desulfurization synergist is prepared by compounding 70-90% by mass of a hydroxyl carboxylate and an organic carboxylate, 9-28% by mass of a scale inhibitor, and 1-2% by mass of a fluorescent tracer, wherein a mass ratio of the hydroxyl carboxylate to the organic carboxylate is an arbitrary ratio. With the present invention, desulfurization efficiency can be significantly improved.

Description

technical field [0001] The invention relates to a desulfurization synergist with scale inhibition performance and a preparation method thereof for a limestone-gypsum wet flue gas desulfurization system (FDG). Background technique [0002] At present, my country's electricity mainly comes from coal-fired thermal power generation. The SO2 produced by coal combustion is more than 100,000 tons per year. In order to reduce the pollution to the atmospheric environment, major power plants have adopted different methods to remove SO2 from boiler flue gas. Except processing. Among them, limestone-gypsum wet flue gas desulfurization has the advantages of mature technology, high removal efficiency, strong adaptability, availability of by-product gypsum, and rich source of absorbent limestone, etc., and is the most widely used in all desulfurization methods. At present, more than 80% of power plants in my country use this method for desulfurization. [0003] Although limestone-gypsum ...
