In desulfuration efficiency, high, stable feature, is widely used in China.In recent years, with Environmental Protection in China dynamics
Constantly reinforce, generated waste water continues to be paid close attention to by people in wet desulphurization operation.
Desulfurization wastewater is mainly the discharge water on absorption tower in boiler smoke process of wet desulphurization.In order to maintain desulfurizer to starch
The balance of fluid circulation substance, preventing part soluble matter in flue gas (main component is chlorine) is more than specified value and guarantee gypsum matter
Amount, it is necessary to a certain amount of waste water is discharged from system, waste water is mainly from gypsum dehydration and cleaning system.What is contained in waste water is miscellaneous
Matter mainly includes suspended matter, oversaturated sulphite, sulfate and heavy metal, wherein most is to want in national environmental standard
Seek the first pollutant of strict control.
The spray evaporation facture of desulfurization wastewater is to carry out the one of spray evaporation processing to waste water in flue or reactor
Kind method.When handling desulfurization wastewater using the method, spray into boiler after first desulfurization wastewater being atomized using certain spray regime

It penetrates, however in the environment of flue or inside reactor high temperature, dusty, high gas flow rate, nozzle easily generates abrasion and stifled
Plug influences system operation, also limits popularization of the spray evaporation method in desulfuration waste water treatment process.Remove the shadow of external environment
Outside ringing, existing jet atomization device receives degree lower the solid content of liquid, when there is residual solid ingredient in waste water, nozzle
Internal blocking is easily generated, atomization is caused to interrupt, so that in order to avoid this problem, it is also another in actual operation to increase waste water
Pretreatment and concentration, except the techniques such as hard turbidity removal, bring cost increase and system operation it is uncontrollable.
Patent CN204714546U describes a kind of high efficiency nozzle for flue gas desulphurization wastewater evaporation, by nozzle
The mode of outlet setting mechanical atomization blade extend the atomization process of drop, be intended that and made by the rotation of mechanical atomization blade
For the droplet after broken atomization, but the defect of this method is: 1) mechanical atomization itself bring breakup of drop effect, right
Almost effect is little for the drop that partial size only has tens microns；2) blade rotated is in high temperature, the cigarette of prosecution dusty, high
It in compression ring border, is easier to wear instead, moistening of contacting with high-temperature flue gas is not yet entered inside flue on blade surface
Dust contact in drop and environment, easily causes to deposit fouling, influences system operation.
Therefore lack a kind of effectively anti-wear anticlogging efficient jet atomization device at present, realize desulfurization wastewater in flue
Or effective evaporation drying in reactor, meet run environmental requirement and stabilization, reliable.
