Abstract
The utility model discloses a desulfurization wastewater treatment device for a power plant. The desulfurization wastewater treatment device comprises a pH regulating tank, a flue and a dust remover arranged on the flue, wherein the pH regulating tank is provided with a wastewater inlet pipeline, an alkaline adding pipe and a stirrer; the flue is internally provided with an atomizer; a wastewater pump delivery device and an aerator are arranged between the pH regulating tank and the atomizer; a temperature measuring device is arranged at the connection part of the flue and the dust remover. The desulfurization wastewater treatment device has the advantages that the complex technical chain in the traditional design is overcome, desulfurization wastewater can be simply and efficiently treated at low cost, meanwhile, the affect of high-concentration chloride ions to the environment is thoroughly overcome, and the zero emission of wastewater is really realized; the investment is reduced by more than 80% as comparison with that in the prior art, the energy consumption is low, and the operation cost is reduced by 90% as comparison with that of the current conversional method; the smoke waste heat is sufficiently utilized, the heavily-polluted desulfurization wastewater is completely evaporated, the humidity of dust-contained smoke which does not enter the dust remover is improved, and the dust removal effect of the dust remover can be favorably improved.
Description
Technical field
The utility model belongs to desulfurizing waste water processing device, is specifically related to a kind of power plant desulfurization wastewater treatment equipment.
Background technology
Power plant desulfurization waste water is one of unmanageable waste water of generally acknowledging at present, and in coal and Wingdale, heavy metal element can enter desulfurization wastewater, is limited to environmental requirement, heavy metals ion must be removed, to meet emission request.It is acid that desulfurization wastewater is, high turbidity, and high viscosity, in waste water, containing the multiple heavy metal ion exceeding standard, suspension content is up to 10000～12000mg/L, and solid content is 1～2%.Larger with traditional wastewater property difference, be difficult to synchronous processing, have to drop into substantial contribution independently desulfurization wastewater treatment system is set.
Utility model content
The purpose of this utility model is high for current desulfurization wastewater processing cost, and the situation that treatment effect is undesirable provides the power plant desulfurization that a kind of cost is low, treatment effect is good wastewater treatment equipment, processes problem thereby efficiently solve desulfurization wastewater.
The technical scheme that realizes the employing of the utility model object is as follows:
The power plant desulfurization wastewater treatment equipment that the utility model provides, comprise pH adjustment tank, flue and be located at the fly-ash separator on flue, described pH adjustment tank is provided with waste water water inlet pipe, adds alkali pipe and agitator, in described flue, be provided with spraying gun, between described pH adjustment tank and spraying gun, be provided with waste water pump e Foerderanlage and aerator, the junction of described flue and fly-ash separator is provided with temperature measuring equipment.
Feature of the present utility model is first to adjust by pH adjustment tank the pH of desulfurization wastewater, then is delivered to flue and fly-ash separator, utilizes the waste heat of flue gas by waste water evaporation imurity-removal, and it has the following advantages:
1, overcome the numerous and diverse technology chain of traditional design, simply high efficiency, low cost is processed desulfurization wastewater, has thoroughly solved the impact of high-concentration chlorine ion on environment simultaneously, realizes the truly zero release of waste water.
2, output investment ratio is saved more than 80% now, and energy consumption is little, and running cost saves 90% than current ordinary method.
3, can realize fully automated, operational safety is simple.
4, make full use of fume afterheat, evaporate heavily contaminated desulfurization wastewater completely, and improve ash-laden gas and enter the humidity before fly-ash separator, be conducive to improve the dust removing effects of fly-ash separator.
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, power plant desulfurization wastewater treatment equipment, comprise pH adjustment tank 11, flue 5 and be located at the fly-ash separator 7 on flue 5, fly-ash separator 7 is connected with chimney 8, described pH adjustment tank 11 is provided with waste water water inlet pipe 1, adds alkali pipe 2 and agitator 3, in described flue 5, be provided with spraying gun 6, between described pH adjustment tank 11 and spraying gun 6, be provided with waste water pump e Foerderanlage 10 and aerator 4, aerator 4 adopts pressurized air to be connected on the outlet conduit of waste water pump e Foerderanlage 10, and the junction of described flue 5 and fly-ash separator 7 is provided with temperature measuring equipment 9.
Principle of work of the present utility model is as follows:
Desulfurization wastewater enters pH adjustment tank 11 by waste water water inlet pipe 1, add after alkali and agitator 3 stir pH is adjusted to processing requirement through adding alkali pipe 2, desulfurization wastewater after pH adjusts is input to spraying gun 6 by waste water pump e Foerderanlage 10 by desulfurization wastewater, desulfurization wastewater is become steam water interface input spraying gun 5 by aerator 4, desulfurization wastewater becomes injection flue 5 after water smoke by spraying gun 6, along flue 5 water smokes by evaporate to dryness, finally enter fly-ash separator 7 by the impurity of desulfurization wastewater along with flying dust deposits, flue gas is discharged into atmosphere through chimney 8, thereby reach the object of processing desulfurization wastewater.Install in servicely, can monitor the flue-gas temperature that enters fly-ash separator 7 by temperature measuring equipment 9, to control the running status of fly-ash separator 7.
