Relational language is explained
Desulfurization wastewater: the waste water handled after power plant desulfurization contains a large amount of pollutants.Suspended matter and soluble-salt
Content it is high, it is weakly acidic, also containing heavy metal substances such as mercury, chromium, cadmium, lead, arsenic.There is corrosivity to metal equipment simultaneously；
Desulfurization wastewater zero-emission: attention and increasingly serious Environmental Protection Situation with country to water resource, desulfurization wastewater
It cannot be directly discharged in environment, the pollutant in waste water be solidified by separation by series of process process, moisture is arranged with flue gas
Atmosphere realizes zero-emission.
6 evaporation technique of flue: desulfurization wastewater is atomized by existing 6 evaporation technique of flue using atomizer, is sprayed into empty
In flue 6 between pre- device and electric precipitator 7, the waste water after atomization is evaporated using fume afterheat, the pollutant in waste water turns
Crystal or salt are turned to, is trapped with flying dust by deduster 7, into 7 ash bucket of deduster with dry ash discharge system.Moisture quilt
Flue gas flashes to a part that water vapour constitutes flue gas, discharges together with flue gas.6 evaporation technology process of flue is simple, throws
It is lower to provide operating cost.
Spray gun: the gun body 1 in the utility model can be twin spray gun, the carrier of atomizer.Two-fluid
For desulfurization wastewater and compressed air.Substantially working medium flow are as follows: compressed air and desulfurization wastewater enter spray gun from two imports respectively,
It is discharged, can be arranged in a system multiple through atomizer after thering is mixing steam chest, compressed air to mix in spray gun with desulfurization wastewater
Spray gun.
Atomizer: being substantially exactly nozzle, utilizes channel (through-flow) device of decompression acceleration principle.With certain pressure
Air and waste water mixture the effect that decompression accelerates can be generated when flowing through nozzle, sprayed with higher flow velocity from nozzle.Due to
It is gas vapor mixture, so forming aerosolized fluid, the profile for spraying formation is conical hollow.
Air nozzle 5: individually accelerate the nozzle of air, decompression accelerates when air flows through nozzle, with high speed mass flowing nozzle.
It filters supercharging device 18: can be the combination of filter device and supercharging device, can also be filter device and pressurization dress
It sets and is used in series.
Air compressor 31: the equipment of compressed air is provided to spray gun.
For the utility model in Datang Envirolution, INC. using certain power plant 300MW unit as application background, operation result shows that its is right
It will not be had an impact in the physical property of flyash and comprehensive utilization, calculate to obtain smoke moisture increase by 0.42%, flue-gas temperature declines 6 DEG C,
Flue gas is still within undersaturated condition, will not corrode flue 6 and deduster 7；It is useless that desulfurization has been carried out by taking certain 300MW unit as an example
The analysis of 6 processing technique of shredded tobacco for water pipes road, the results showed that atomizer selects maximum particle diameter less than 109 μm, 90% desulfurization wastewater amount mist
Change partial size within 90 μm, flue-gas temperature drops to 140 DEG C by 144 DEG C, is higher than 130 DEG C of acid dew-point temperature；Vapor in flue gas
Volume fraction be increased to 6.02% by 5.78%, using 6 evaporation process scheme of flue, there is certain water saving potential.This is practical new
Type can position between air inlet pipe 12 and bypass pipe 13 threeway is installed, the right end of sealed jacket 3 is turned in atomizer position,
Channel bend formula is formed, is then symmetrically installed six air communicated with collet chamber 4 on the right end bottom periphery of sealed jacket 3
Nozzle 5, each 5 longitudinal center line of air nozzle and atomizer longitudinal center line are at 10 degree to 20 degree angles.
The beneficial effects of the utility model
(1) compressed air another part enters the collet formed between sealed jacket 3 and gun body 1 by bypass pipe 13
In chamber 4, air conduction performance is poor, frequently as thermal insulation layer.Thus, the air in collet chamber 4 can effectively weaken flue gas and take off
The heat exchange of sulphur waste water plays insulation effect to desulfurization wastewater (insulation effect is to avoid the temperature of desulfurization wastewater significantly raised).
It can be effectively reduced the journey that taper atomizer 2 of the soluble-salt in desulfurization wastewater on gun body 1 exports fouling in this way
Degree；
(2) mix that (desulfurization wastewater is consumed with desulfurization wastewater in the cavity of gun body 1 due to a part of compressed air
The pressure of portion of air), so the pressure in gun body 1 is less than the pressure in collet chamber 4, this makes air nozzle 5
On front and back pressure difference be greater than taper atomizer 2, while flue gas to air heat so that air themperature slightly rise, enthalpy
It increased.It is depressured speedup principle according to nozzle, 5 outlet air flow velocity of air nozzle certainly will be greater than taper atomizer 2, air
Air-flow (substantially with the air draught of impact capacity, alternatively referred to as impact air-flow) can be to desulfurization wastewater atomizing fluids
(hollow cone) forms impact, interference, expands the spray area of desulfurization wastewater atomizing fluids, accelerates desulfurization wastewater atomized drop and cigarette
The blending of gas, and the rupture of atomized drop can be promoted to be conducive to flue gas blending by percussion, have and shorten the blending time,
Weaken the excessive advantage of flue gas local humidity.
The above technical characteristic constitutes the embodiments of the present invention, with stronger adaptability and best implementation effect
Fruit can increase and decrease non-essential technical characteristic, according to actual needs to meet the needs of different situations.
