Technical field
Boiler water treatment field is the utility model is related to, particularly a kind of temporary hardness boiler feed water corrosion-mitigation scale-inhibition water process
System.
Background technology
The hardness of water is mainly by calcium (Ca therein2+), magnesium（Mg2+）What ion was formed, carbonate is very in natural water
It is few, so carbonate hardness regards the bicarbonate hardness of calcium, magnesium as.Generally, the hardness of such salt is when water is heated boiling
Precipitation, referred to as temporary hardness will be produced.If containing hardness salt in boiler feed water, water can be generated on boiler heating surface
Dirt, substantially reduce heat transfer efficiency.Simultaneously as fouling causes heating surface metal superheat to damage, such as bulge, booster, therefore, pot
Stove water fouling is an important factor for influenceing boiler safety, economical operation.Meanwhile the oxygen and carbon dioxide dissolved in water can also be to pot
Stove and pipeline produce oxygen corrosion and sour corrosion, reduce the therrmodynamic system life-span.
At present, the method for boiler water process mainly has two kinds, when water treating method in stove, i.e., as feedwater is thrown into boiler
Add a number of water softener, the scale forming matter in water is transformed into the flowable dirt for falling to the bottom, then passes through row
Dirt excludes dirt.Water process can not entirely prevent fouling in stove, particularly established dirt, blowdown not in time when hold very much
Easily form secondary incrustation scale.Especially when feed-water hardness is too high, a large amount of grain slags will be formed, accelerate the formation of secondary incrustation scale, therefore
Water treating method is not suitable for high-hardness water in stove, second, the outer water treating method of stove, raw water use water process before boiler is entered
The hardness that equipment is gone in water removal, common softened water equipment have sodium ion exchange softened water equipment, reverse osmosis water purifying plant etc..Through
Cross the outer water process of boiler and there may also be residual harness later.
By foregoing, current boiler water process can only achieve the purpose for slowing down fouling, and for temporary hardness with
Dampening temperature rise, heavy carbonic root can split the carbon dioxide off, and can cause sour corrosion to boiler and steam pipework.On the other hand, do not have also
There is the method for carbon dioxide eliminating, the sour corrosion of therrmodynamic system does not draw attention, especially therrmodynamic system steam side
Equipment, pipeline sour corrosion are not protected, and corrosion phenomenon is than more serious.In practice there is still a need for be aided with stove dosing and
Periodic cleaning, it can be only achieved boiler safety, the target of economical operation.
