Abstract

The invention relates to a self-stirring aeration system for a wastewater regulating tank of a flue gas desulfurization system. The system comprises a wastewater regulating tank, an air leading main pipe, a lower-layer self-stirring air exhaust pipe, an upper-layer self-stirring air exhaust pipe and a pulse nozzle, wherein the air leading main pipe is arranged outside the wastewater regulating tank, and the input end of the air leading main pipe is capable of inputting air; the output end of the air leading main pipe is connected with the upper-layer self-mixing air exhaust pipe and the lower-layer self-stirring air exhaust pipe, and the top of the air leading main pipe is arranged above the top of the wastewater regulating tank. The system has a self-stirring function, replaces an electromechanical stirrer of a wastewater regulating tank, and has the advantages of simple equipment, sufficient stirring, long service life, simplified process control and reduced fault points, effective reduction in investment and maintenance costs, and safe and reliable operation, has the characteristics of high aeration efficiency, sufficient and uniform mixing and long residence time compared withthe traditional aeration method, and can be widely applied to the stirring aeration system of the wastewater regulating tank.

Description

technical field [0001] The invention belongs to the technical fields of chemical industry and environmental protection, and relates to a self-stirring aeration system, in particular to a self-stirring aeration system of a waste water regulating tank of a flue gas desulfurization system and its application. Background technique [0002] During the continuous circulation process of flue gas desulfurization system slurry, heavy metal elements and Cl will be continuously enriched. - etc. On the one hand, these substances will accelerate the corrosion of desulfurization equipment, and on the other hand, they will affect the quality of gypsum. Therefore, in order to ensure the quality of gypsum and control the Cl in desulfurization equipment - concentration, the desulfurization system needs to discharge a certain amount of wastewater regularly to maintain the stable operation of the system. Desulfurization wastewater contains high concentrations of suspended solids, heavy metal i...
