Application Status and Analysis of Flue Gas Evaporation Technology for High Temperature Bypass of Desulfurization Wastewater in Coal-fired Power Plants

By comparing the mechanical rotation and dual-fluid high-temperature bypass flue evaporation technology,the atomization principle,key parameters,core equipment and engineering application of the two technologies were introduced,and the high-temperature bypass flue evaporation technology was summarized in the zero discharge of desulfurization wastewater. The status of the application in the treatment,a comparative analysis of the problems in the application,and the countermeasures were put forward,in order to provide a reference for the engineering application of the zero discharge treatment of desulfurization wastewater in coal-fired power plants.
