Water collection type dedusting demister and system.
Background technique
Water balance is the important balance in WFGD system, quality of the water circulation rate to the stabilization gypsum of system, the material of equipment
The selection of material has important influence.Content of the size of water circulation rate to the solid component in the slurries in absorption tower and pipeline
It can have a certain impact, especially the lesser component of particle.
Such as increase water circulation rate, that is, reduce the discharge amount of waste water, then can in larger fluid Cl ion and sulfate radical content,
High, the purity difference of gypsum is required to the material of equipment pipe.But if increasing the discharge amount of waste water, it will increase wastewater treatment
The construction cost of system and the operating cost of wastewater treatment, while water consumption increases.
So reasonable selection, determines that water balance designs optimization system, cost is reduced, and water conservation has to pass
Important role.
And controlled level weighing apparatus then needs control system water and system water consumption.Wet desulfurization system can be divided into 5 major class with water:
Limestone pulping water, equipment rinse water, equipment cooling water, starting/adjustment water and waste water treatment system water；And it is
The water consumption point of system mainly has: the water (water is evaporated in tower) that flue gas is formed after being brought into atmosphere in a gaseous form, flue gas is with liquid
The water that the form of state water is formed after being brought into atmosphere, the discharge of attached water and the crystallization water and FGD system when gypsum is discharged
Waste water.
Along with the promotion of boiler efficiency and the utilization of flue gas reheat system, desulfuration absorbing tower entrance flue gas temperature exists
Reduced trend, thus bring the reduction of system water consumption evaporation capacity so that control desulfuration absorbing tower in water balance it is further difficult.
Therefore as can the falling of mist eliminator flushing water is greatly reduced, then systematic water balance can be easy
The demister of now widely used wet method fume desulfurizing system, to prevent it from causing to block up because of slurries crystallization
Plug, and then demisting efficiency and service life of equipment are influenced, a large amount of flushing waters need to be used to be timed flushing to demisting component.This portion
Divide flushing water, can fall after rise in current operating condition into the slurry pool of absorb the bottom of the tower.
