Description
Technical field
The utility model relates to environment protection desulphurization technical fields more particularly to a kind of wet desulphurization slurry pH value and density to combine
Detection device.
Background technique
Recent years, with the serious of environmental pollution, country has put into effect a series of policies and thermal power plant is encouraged to implement to surpass
Low emission transformation, is transformed after-burning coal smoke power-plant flue gas SO2Concentration of emission requires control in 35mg/Nm3Hereinafter, this is to desulphurization system
Safe and economical operation proposes tightened up requirement.
Currently, smoke-gas wet desulfurization is the highest desulfurization technology of current desulfuration efficiency, using also the most extensively, in lime
In stone-gypsum wet desulphurization system, it is Limestone-gypsum Wet Flue Gas Desulfurization Process that desulfurizing tower, which holds gypsum slurries pH value in liquid bath and density,
Two important parameters, the operation of whole system, control are played a crucial role.Under normal circumstances, absorption tower slurries
PH value should control between 5.0~5.4, while guaranteeing that the indexs such as desulfuration efficiency reach requirement, reduce system energy consumption；Operation
The density of middle gypsum slurries should be controlled in (1080~1100kg/m in a suitable range3), be conducive to desulphurization system
Efficiently, economic and safe operation.In view of the importance of two above control parameter, it is therefore necessary to hold gypsum in liquid bath to desulfurizing tower
