Be Limestone-gypsum Wet Flue Gas Desulfurization Process technique, in wet desulphurization device running can the substantial amounts of desulfurization wastewater of periodic exhaustion,
Containing a large amount of impurity in desulfurization wastewater, such as float, inorganic ion, heavy metal ion etc., could arrange after needing purified treatment
Put.Currently, domestic and international desulfuration waste water treatment process mainly uses physico-chemical process to remove Pollutants in Wastewater, has system complex,
Investment and operating cost are high, it is impossible to solve the shortcomings such as the impact that in waste water, wastewater reuse is caused by chloride ion, have a strong impact on
The commercial introduction of various desulfuration waste water treatment process, economic benefit and the strict environmental protection that also cannot meet coal-burning boiler user are wanted
Ask., being affected by shortage of water resources problem, environmental administration requires that coal unit reduces discharging waste water further, it is achieved waste water meanwhile
Zero-emission.At present, the domestic desulfurization wastewater zero discharge treatment measure also having the different process such as degree of depth extraction, evaporative crystallization method,
But all there is equipment manufacturing cost and operating cost is high, it is impossible to the problem of popularization and application.Thus, a kind of system of research and development is simple,
Without increasing complex device and investing the low employing of operation and maintenance cost layout double fluid in air preheater outlet horizontal flue
The desulfurization wastewater evaporation zero discharge treatment device that spray gun body adds compression air-assisted atomization is significant.
Utility model content
The purpose of this utility model is that wet desulphurization method of wastewater treatment system is huge, investment is higher, operation for commonly using at present
Maintenance cost is higher, dissolubility Cl-And F-Poor removal effect, Cl-Under acid condition, corrosivity is big and waste water cannot reclaim profit
Problem, and provide a kind of wet desulphurization wastewater zero discharge processing means.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of wet desulphurization wastewater zero discharge processing means, wherein: include that desulfurization wastewater storage tank, delivery pump, compressed air are stored up
Tank, two-fluid spray gun and air preheater outlet horizontal flue；Described two-fluid spray gun exports horizontal cigarette with air preheater
The upper wall surface in road is fixing to be connected；The described outlet at bottom of desulfurization wastewater storage tank is connected by liquid phase pipeline with the import of delivery pump
Logical, described conveying delivery side of pump is connected by liquid phase pipeline with the fluid inlet of two-fluid spray gun；Described compressed air
The outlet of storage tank is connected by gas phase pipeline with the gas phase import of two-fluid spray gun.
Compared with prior art, this utility model has the advantage that
1, this utility model device processes the processing procedure of bulky complex without increasing existing desulfurization wastewater, and overall investment is less,
System is simple, saves ample resources, and later stage operation and maintenance cost is relatively low, it is possible to decrease cost of electricity-generating, has significant warp
Ji property.
2, this utility model device uses and arranges two-fluid spray gun in air preheater outlet horizontal flue, increases pressure simultaneously
Contracting air-assisted atomization system by desulfurization wastewater atomization for minimum droplet, realize within short time and the confined space high-temperature flue gas with
Being fully contacted of waste water droplet, makes waste water droplet be evaporated completely by high-temperature flue gas, absorb, really realizes the zero-emission of desulfurization wastewater
Put.Simultaneously, it is to avoid desulfurization wastewater evaporates the most entirely to problems such as the corrosion that cleaner unit, flue and follow-up equipment cause.
3, this utility model device is provided with compressed air reservoir, the compressed air in compressed air mother's pipe is cached,
Can avoid causing two-fluid lance end atomizing pressure because multiple spot compressed air conductance causes the fluctuation of compressed air main-piping pressure
Impact, be effectively guaranteed the overall even running of this device.
4, in this utility model device, desulfurization wastewater is finally evaporated completely by high-temperature flue gas, absorbs, and flue-gas temperature can be made to have one
Determine the decline of degree, then exhaust gas volumn reduces, and air-introduced machine acting reduces, and effectively reduces the power consumption of air-introduced machine；Meanwhile, wet method
Desulfurizing tower inlet flue gas temperature also decreases, and decreases the evaporation water consumption of desulfurization slurry, reduces technique moisturizing, has preferably joint
Can consumption reduction effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, the present embodiment one wet desulphurization wastewater zero discharge processing means, wherein: include desulfurization wastewater storage tank
