Description
Technical field
The present invention relates to water-treatment technology field, more specifically, relate to water treatment reagent, particularly a kind of Phosphateless environmentally friendly corrosion and scale inhibition disperser and its preparation method and application.
Background technology
Along with the sharply increase of industrial mass-producing and population, water resources is seriously deficient.Circulating cooling water consumption accounts for the 60%-70% of process water, rationally saves the most direct way that recirculated cooling water is reduction industrial water consumption.The main method of saving recirculated cooling water improves the cyclic utilization rate of recirculated cooling water, namely strengthen cycles of concentration, but this can bring serious corrosion and scale problems to circulating water system again, has higher requirement to water technology.In order to ensure that circulating water system is normally run under the conditions such as high rigidity, high Cl-concentration, high organic concentration, water treatment agent seems very crucial.
In treatment of industrial water, the recirculated cooling water comprising oilfield sewage, chemical enterprise and power station all relates to preventing fouling.In the development experience of the scale inhibitor stages such as inorganic salt, polyelectrolyte, natural polymer, organic phosphoric acid, polymkeric substance, copolymer antisludging agent is the innoxious water conditioner of a class of the exploitation eighties.Most widely used is at present organic phosphoric acid Scale inhibitors, and as Amino Trimethylene Phosphonic Acid (ATMP), hydroxy ethylene diphosphonic acid (HEDP) etc., but P contained compound can cause environment water eutrophication, causes pollution of waterhead.Therefore oneself becomes important research direction outside Now Domestic to develop without phosphorus, environmentally friendly green scale inhibitor.
In addition, along with the development of water technology, people have higher requirement to dirt dispersion agent.Be mainly reflected in two faces: one is except the ability except having resistance calcium carbonate, calcium phosphate etc., also requires that dirt dispersion agent has good dispersing iron oxide ability, with the impact of the deposition heat exchanging effect and metallic corrosion that alleviate iron dirt; Two is due to zinc salt a large amount of uses as inhibiter principal constituent in water treatment agent, causes zinc dirt very easily to deposit, and requires that dirt dispersion agent has ability that is stable, dispersion zinc salt simultaneously for this reason.That is, exploitation have multifunctional anti-incrustation dispersion agent that resistance calcium carbonate, calcium phosphate scale have dispersing iron oxide and stable zinc salt ability concurrently become water treatment field in the urgent need to.For this reason, some multipolymers containing different functional groups monomer are developed, as CN101264986 reports a kind of copolymer-maleic anhydride, still there is good antiscaling dispersion ability under high-calcium ionic concentration, and having the ability of dispersing iron oxide concurrently, CN101186394B reports a kind of dirt dispersion agent, is formed by vinylformic acid, acrylamide and sulfonic acid monomer copolymerization, not only have good resistance calcium carbonate scale ability, and there is outstanding dispersing iron oxide ability.CN101279798 reports a kind of toxilic acid, maleic mono-ester and acrylic copolymer dirt dispersion agent, has good scale inhibition and dispersion performance to calcium carbonate, has satisfactory stability zinc salt ability simultaneously.Although by the multifunctionality achieving copolymer anti-scale disperser containing the combination of different functional groups monomer, in order to keep it multi-functional, these polymeric scale inhibitor dispersion agents sacrifice some other performances more or less.As, in order to make polymkeric substance have satisfactory stability zinc salt and dispersing iron oxide ability, the resistance calcium carbonate ability of sacrificial section of having to.Therefore the emphasis that performance is all good in every respect copolymer anti-scale disperser remains water treatment worker is developed.
Summary of the invention
The object of the invention is to, for the above-mentioned limitation of prior art, provide a kind of without phosphorus, environmental protection and dirt dispersion agent of excellent performance and preparation method thereof.Non-phosphorus scale dispersion agent of the present invention not only has outstanding antiscaling dispersion ability to calcium carbonate and calcium phosphate, and has dispersing iron oxide and stable zinc salt ability concurrently.In addition, research finds: the ammonium tungstate in the present invention and sodium tartrate and silicate are combined has inhibition synergism, greatly can reduce the usage quantity of single medicament, with form compound prescription containing carboxylic acid group's Phosphate-free copolymer dirt dispersion agent and has and effectively suppress calcium phosphate scale, zinc dirty and disperse the performance of calcium carbonate scale, be applied to circulating water treatment and can solve conventional organic phosphine medicament because phosphorus content is high to the harm of environment.Further, in the present invention, without phosphorus polymeric scale inhibitor dispersion agent is that two kinds of carboxylic acid polyalcohol dirt dispersion agents are composite, has more excellent performance than single polymeric scale inhibitor dispersion agent.
