Abstract
The invention relates to the technical field of wet desulfurization and discloses a desulfurization foaming treatment system and method based on slurry quality optimization. The system is connected with an upper portion of a slurry tank of an absorption tower through an overflow slurry discharge pipeline and comprises a slurry buffer tank, a waste water cyclone station and a vacuum belt conveyor,wherein a liquid outlet of the overflow slurry discharge pipeline is connected with a liquid inlet of the slurry buffer tank; the liquid outlet of the slurry buffer tank is connected with a first conveying pipe; a material falling device is arranged at the liquid outlet of the first conveying pipe; the material falling device is positioned above a conveyor belt of the vacuum belt conveyor at a position where a solid filter cake forms; a second conveying pipe is also connected with the first conveying pipe; the liquid outlet of the second conveying pipe is connected with the waste water cyclonestation; an overflow tank of the waste water cyclone station is connected with a waste water storage tank through a waste water output pipe; and a bottom flow tank below the waste water cyclone station is connected with the first conveying pipe. The desulfurization foaming treatment system has simple structure, can effectively separate impurities in the slurry from a slurry circulating system, and avoids the foaming of the slurry fundamentally.
Description
technical field [0001] The invention relates to the technical field of wet desulfurization, in particular to a desulfurization foaming treatment system and treatment method based on slurry quality optimization. Background technique [0002] In the flue gas desulfurization process of thermal power plants, the gypsum slurry in the desulfurization device will continue to circulate due to factors such as insufficient boiler combustion, poor electrostatic precipitator effect, process water quality that does not meet the design requirements, or excessive MgO content in limestone. In the process of desulfurization, it is enriched with very fine dust, insoluble matter, unburned matter, heavy metals and oily substances. The accumulation of these impurities to a certain extent will lead to foaming of the desulfurization slurry, which will affect the efficiency of the desulfurization device and even affect the performance of the desulfurization system. Safe and stable operation. [00...
