Abstract
The utility model relates to a kind of device of flexible modulation desulfurization spray flux, refers in particular to and transforms desulfurization spraying layer.Former absorption tower and spraying layer constant, below former the superiors absorption tower, the newly-increased little spraying layer 3 of one deck, makes slurries amount meet the demands.Mainly newly-increased spraying layer, comprising mother's pipe, arm, nozzle.Newly-increased spraying layer is fixed on original brace summer by pipe support.The keying of this layer is controlled additionally by two rotating speed motor 2 and control valve 1.This transformation makes desulphurization system stronger to load, coal sulfur adaptability, for different operating mode, regulates space larger.Flue gas can be avoided to escape from former spray supervisor and brace summer position, and serum recycle amount gets a promotion simultaneously, and desulfuration efficiency promotes obviously.Load according to flue gas regulates spray flux; The waste of slurries is avoided while raising the efficiency.
Description
Technical field
The utility model relates to device technique field, power plant desulfurization absorption tower, specifically transforms the lime stone slurry spraying layer above absorption tower.
Background technology
Along with country is to the increasing of environment protection treating dynamics, SO in power-plant flue gas
2concentration of emission can not meet the demands.Reach emission request, lime stone slurry quantity not sufficient originally, so slurries amount will be increased.
Summary of the invention
The utility model is for the deficiencies in the prior art, the basis of existing equipment is transformed spraying layer, below the spraying layer of upper strata, increase one deck slurries spraying layer, the layout of this layer of spraying layer, the quantity comprising the caliber of female pipe, arm and nozzle is determined according to required slurries amount.Wherein carry the pump of slurries and upper strata spraying layer to share, only original common electric machine need be transform as two rotating speed motor, controlled the keying of spraying layer by the rotating speed changing motor.A control valve is had between slurries spraying layer and slurry circulating pump.Slurries spraying layer is fixed on the brace summer of upper strata spraying layer.
Advantage of the present utility model is:
1, desulphurization system can be made stronger to load, coal sulfur adaptability, for different operating mode, regulate space larger.
2, flue gas can be avoided to escape from former spray supervisor and brace summer position, and serum recycle amount gets a promotion simultaneously, and desulfuration efficiency promotes obviously.
3, after transformation, desulphurization system runing adjustment space is large, and energy-saving effect is remarkable.
4, make full use of the allowance of original slurry circulating pump, retrofit work amount is little, and improvement cost is low.
Accompanying drawing illustrates:

Detailed description of the invention:
There are three layers of lime stone slurry spraying layer on former absorption tower, and the corresponding slurry circulating pump of every one deck.The utility model, under the prerequisite of not changing miscellaneous equipment and device, sets up one deck slurries spraying layer below the spraying layer of upper strata, and the quantity of the caliber of female pipe of this layer of spraying layer, arm and nozzle is determined according to required slurries amount.General spray flux is 20% of former spray flux, about 1000-2000m
3the caliber of the female pipe of/L is at 300mm-350 mm.Carry the slurry circulating pump of this layer of slurries and upper strata spraying layer to share, because the flow of virgin pulp liquid circulating pump has the allowance of 20%, can meet the demands completely.Only original common electric machine need be transform as two rotating speed motor.
Position: slurries spraying layer is arranged near upper strata spraying layer, and the arrangement of nozzle will avoid upper strata slurries, avoids washing away pipeline.This layer of spraying layer is fixed on the brace summer of upper strata spraying layer by the a-f point in Fig. 4.
Regulative mode: this device controls the closure or openness of slurries spraying layer by the rotating speed changing motor; Spray flux is regulated by the control valve between spraying layer and slurry circulating pump.When the load of flue gas is larger, two rotating speed motor 2 is set to large rotating speed, and control valve 1 is opened, and slurries spraying layer runs thus provides more spray flux; When flue gas load amount is less, two rotating speed motor 2 is set to little rotating speed, and control valve 1 cuts out, thus avoids the waste of slurries.
