Desulfurization waste water sludge treatment system

Abstract

The invention discloses a desulfurization waste water sludge treatment system, comprising an evaporation tower, a clarification pond, a reverse flushing system installed at a conical part of the clarification part, a sludge water output pipeline installed at the bottom part of the clarifying pond, a circular pump installed on the sludge water output pipeline, a sludge water misting spraying device installed on the tail end of the sludge water output pipeline, and a static dust removal device for mounting a misting nozzle of the sludge water misting spraying device in a smoke flue; the static dust removal device comprises a static dust remover, a bypass smoke flue closing to a smoke inlet and a smoke outlet of the static dust remover, and an induced draft fan closing to the smoke outlet of the static dust remover and installed on the bypass smoke flue. The desulfurization waste water sludge treatment system is simple in structure, low in investment, low in running cost; the system saves water and material, the waste material can be comprehensively used, thus the system is environment-friendly, and realizes the zero emission of the desulfurization waste water sludge, is low in energy consumption and energy-saving. The system is widely applied to the desulfurization waste water sludge treatment of a limestone-gypsum wet method smoke desulfurization system of a power station boiler and an industrial boiler.

Description

technical field [0001] The invention relates to a desulfurization wastewater sludge treatment system, which can be widely used in the desulfurization wastewater sludge treatment of limestone-gypsum wet flue gas desulfurization systems of power station boilers and industrial boilers. Background technique [0002] In the limestone-gypsum wet flue gas desulfurization system, in order to ensure the desulfurization efficiency and maintain the chloride ion balance of the system, part of the desulfurization wastewater needs to be discharged. Because the wastewater contains a large amount of dissolved salts, suspended solids and a small amount of harmful pollutants such as fluoride ions and heavy metal ions, it cannot be discharged directly. [0003] At present, the commonly used desulfurization wastewater treatment process is to use chemical treatment methods to flocculate, settle and neutralize the wastewater to reduce suspended solids and harmful substances in the wastewater, and...

Problems solved by technology

Due to the limited effects of the usual chemical treatment methods and the difficulty in treating neutral salts, it is difficult to recycle waste water and discharge it to the outside world.
