Description
Technical field
The present invention relates to desulfurization wastewater flue spray evaporation processing units, and in particular to a kind of low energy consumption block-resistant type atomization spray
Injection device.
Background technology
Limestone-gypsum wet flue gas desulfurization (FGD) is current technology in the world sulfur removal technology the most ripe.The method by
In desulfuration efficiency is high, stable the characteristics of, it is widely used in China.In recent years, with Environmental Protection in China dynamics
Constantly strengthen, 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 which desulfurizer is maintained to starch
The balance of fluid circulation substance prevents part soluble matter in flue gas (main component is chlorine) to be more than specified value and ensures gypsum matter
Amount, it is necessary to a certain amount of waste water is discharged from system, waste water is essentially 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 be wanted in national environmental standard
Seek the first pollutant strictly controlled.
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, boiler is sprayed into after desulfurization wastewater is atomized using certain spray regime first
In flue or reactor before afterbody deduster, waste water rapid boil-off gas after high-temperature flue gas heats in the form of droplet
Change, suspended matter and soluble solids therein form fine solid particles, then enter deduster under the entrainment effect of air-flow
And the removal that is captured, the final waste water near-zero release processing for realizing desulfurization.
As it can be seen that handling desulfurization wastewater using spray evaporation method, the atomization process of drop is crucial part therein.Into cigarette
The droplet size of road or reactor is smaller, bigger with the contact area of flue gas, and the transmission speed of heat and quality is faster, drop
Evaporation rate it is also faster, whereas if cannot evaporate in time, the drop of moistening easily with the dust agglomerations in flue gas, together
When also bring the harmful effects such as burn into structure to flue.
In real process, the atomization process of drop mostly stretches into flue using two-fluid spray nozzle or inside reactor is sprayed
It penetrates, however in the environment of flue or inside reactor high temperature, high dust, high gas flow rate, nozzle easily generates abrasion and blocks up
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 relatively low the solid content of liquid, when there is residual solid ingredient in waste water, nozzle
It easily generates inside to block, atomization is caused to interrupt, so that in order to avoid this problem, also separately increase waste water in actual operation
Pretreatment and concentration, except techniques such as hard turbidity removals, 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
Outlet the mode of mechanical atomization blade is set to 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 it is the defects of this method：1) breakup of drop effect that mechanical atomization is brought in itself is right
Almost effect is little for grain size only has tens microns of drop；2) blade rotated is in high temperature, high dust, the high cigarette prosecuted
In compression ring border, abrasion is susceptible to all the better, and the moistening contacted inside flue with high-temperature flue gas is not yet entered 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.
