Abstract
The ion exchanging type antiscale agent of softening water is a kind of being specially adapted to water in the heating boiler, softens the chemicals of processing and boiler compounds.This scale inhibitor mainly contains the metaphosphoric acid salt, chemical substances such as soda ash, Weibull and unslaked lime, its aqueous solution is with in water easily behind the reactive metal oxide on scale forming matter and the container wall, not only can on boiler or other metal wall, form fine and close protection rete, and scale forming matter is had accelerate precipitation and ramollescence.Prevent the fouling of boiler wall effectively, and be easy to remove sedimentary foulant.
Description
The present invention is a kind of mixed preparation of chemical substance.Be specially adapted to the antiscale of various heating with water softening processing and boiler.
At present, the boilercomposition commonly used and the various devices of softening water though can soften processing to water, all can not solve hard forever material (MgCO in the water well
3, MgCl
2Deng) scale problems, often add the fouling of hot water facility because of the sedimentation effect difference causes boiler or other.It is poor to exist detergency especially, and the scale inhibitor consumption is big or equipment is complicated, deficiencies such as waste water.
The object of the present invention is to provide a kind of scale removal preparation that is specially adapted to water in the heating boiler is softened processing and boiler compounds.Said preparation is by the easy ion exchanging type physical chemical process of scale forming matter in each chemical substance wherein and the water, not only can and add on the metal vessel wall of hot water at boiler to form the antiscale rete, and scale forming matter is had accelerate precipitation and ramollescence.Prevent gyp effectively, and be easy to remove sedimentary scale forming matter in container.
The preparation and the using method of this scale inhibitor are:
1, scale inhibitor is the powdered composition that contains chemical substances such as metaphosphoric acid salt, soda ash, Weibull and unslaked lime.Wherein the content of inclined to one side microcosmic salt class is that the content of 25-30%, soda ash is 60-70%, and the content of Weibull is 6-7%, and the content of unslaked lime is 2-3%.
2, after the warm water dissolving with 40-50 ℃ of scale inhibitor usefulness, add plant ash (or potato starch) and a certain amount of caustic soda, make mother liquor after the filtration, again in 500(water): the ratio 1(mother liquor) is used for the scale control treatments of water, and this moment, the pH value of water was 8.5-10.
3, when this scale inhibitor is used for softening heating boiler water and boiler compounds, can press 1000m in the feeding engine ingress of boiler
2Heating area is thrown in the ratio demand of 20 kilograms of scale inhibitors, certain volumetrical medicament delivery pond is set, the heating water can directly be sent in the boiler by recycle pump behind this pond, also can acquire a pond that contains plant ash again and filter behind the medicament delivery pond, and post precipitation pumps in the boiler and uses.The pH value of water remains in the scope of 8.5-10 in the boiler for assurance pumps into, and should add a certain amount of caustic soda again in throwing in the pond.
The principle of softening water of the present invention and antiscale is:
1, chemical precipitation is softening handles:
This process mainly is a unslaked lime soluble in water, the Ca(OH that is generated)
2Remove with water in temporarily hard substance reactions such as the calcium bicarbonate that contains and heavy carbonic magnesium generate CaCO
3And Mg(OH)
2Outside the throw out, also generate calcium salt (CaCO with hard forever substance reaction such as magnesiumcarbonate, magnesium chloride
3, CaCl
2), and make CO in the water
2Gas forms CaCO
3Precipitation.Be mainly used in the hardness of calcium salt in the softening water after soda ash in the medicament is water-soluble.
2, form the good antiscale property rete:
Metaphosphate ion in the aqueous solution of scale inhibitor and the ion in the Weibull can be respectively with water in hydrogen, chlorion reaction after again with the Fe of wall
3O
4And Fe
2O
3Reaction, in boiler, perisporium generates ferric tannate and tricresyl phosphate iron mixture, and this material has bigger density also evenly and securely attached on the perisporium.Neither continuous thickening can prevent that again objectionable impurities is to the corrosion of wall in medicament and the water with the scale forming matter of regeneration is bonding.
3, accelerate sedimentation speed:
After in water, adding caustic soda, carbanion in the plant ash Potassium Absorption water soluble in water, can accelerate on the one hand the cohesion and the sedimentation speed of foulant, on the other hand also further the loose deposit material become soft deposit seeds, be easy to from the mud hole of boiler, release.
The technical progress that the present invention is obtained:
1, this scale inhibitor aqueous solution can prevent again that by both having eliminated the fouling of wall with the wall metal oxide formed protection rete that reacts chemical substance is to the corrosion of wall in medicament and the water.
2, the present invention is when the antiscale that is used for heating boiler, and it is easy to have a preparation, and it is convenient to throw in, and consumption is few, does not need to acquire distinguishing features such as complex apparatus.Antiscaling effect be easy to remove aspects such as settling and all be better than other similar chemical scale inhibition preparation.
3, can be widely used in metal (the copper aluminium etc.) utensil of heating undrinkable water, the antiscaling, descaling effect is remarkable.
Claims (3)
1, a kind of ion exchanging type antiscale agent of softening water is made up of chemical substances such as phosphoric acid salt, bases and supplementary additive etc., it is characterized by this scale inhibitor is the powdered composition that contains chemical substances such as sodium-metaphosphate salt, soda ash, Weibull and unslaked lime, wherein the content of sodium-metaphosphate salt is 25-30%, the content of soda ash is 60-70%, the content of Weibull is 6-7%, and the content of unslaked lime is 2-3%.
2, scale inhibitor according to claim 1, it is characterized in that this scale inhibitor adds plant ash (or potato starch) with 40-50 ℃ warm water with its dissolving back and mother liquor is made in the filtration of a certain amount of caustic soda, again in 500(water): the ratio 1(mother liquor) is used for the scale control treatments of water; This moment, the pH value of water should be 8.5-10.
3, scale inhibitor according to claim 1 and 2 is characterized in that can pressing 1000m in boiler water filling pump inlet place when scale inhibitor is used for softening heating boiler water and boiler compounds
2The ratio demand that heating area is thrown in 20 kilograms of scale inhibitors is provided with certain volumetrical medicament delivery pond, the heating water is behind this pond, can directly send in the boiler, also can behind the medicament delivery pond, acquire a pond that contains plant ash again and carry out pumping in the boiler again behind the filtering-depositing and use by recycle pump;
The pH value of water remains in the scope of 8.5-10 in the boiler for assurance pumps into, and should add a certain amount of caustic soda again in throwing in the pond.
