The invention provides an efficient anti-wall-sticking desulfurization wastewater drying treatment system. Comprising a desulfurization wastewater storage system, a heating system, a water temperature controller, a drying tower, a high-temperature flue gas channel and a dust remover. The desulfurization wastewater storage system is used for storing desulfurization wastewater; the inlet of the heating system is the concentrated desulfurization wastewater, and the outlet of the heating system is the heated desulfurization wastewater; the water temperature controller is connected with a heating system outlet heat source; and the lower outlet of the drying tower is connected to the inlet of the boiler dust remover. The invention provides an efficient anti-wall-sticking desulfurization wastewater drying treatment system which is used for heating desulfurization wastewater to a critical temperature interval and then spraying the desulfurization wastewater into a drying tower. The evaporation and gasification time of the desulfurization wastewater is shortened, the desulfurization wastewater is rapidly and completely evaporated and dried, the wall sticking of the drying tower is avoided, and the stable operation of the power plant desulfurization wastewater drying system is ensured.
Description
technical field [0001] The invention relates to the field of high-temperature flue gas drying treatment of desulfurization wastewater, in particular to a high-efficiency anti-sticking wall desulfurization wastewater drying treatment system. Background technique [0002] Wet desulfurization technology is widely used in the flue gas treatment of coal-fired boilers. The desulfurization agent is mostly limestone or lime. However, this technology will generate a large amount of desulfurization wastewater during operation. The desulfurization wastewater treatment system currently invested in power plants is not effective. The quality and quantity of water to be treated is problematic, and the treated water does not meet the reuse standard. These highly polluting desulfurization wastewater has nowhere to go. Discharge after treatment can no longer meet the requirements of resource utilization and ecological protection in my country at the present stage. [0003] At present, the mo...
