Description
Technical field
The present invention relates to a kind of water-treating agent of boiler, more particularly to a kind of without phosphorus low sodium boiler water corrosion-mitigation scale-inhibition
Agent.
Background technology
Boiler is essential equipment in modern production.In recent years, Boiler Manufacturing Enterprise quantity cumulative year after year, speedup
Surprising, the usage quantity of boiler also constantly rises in the industry such as fire coal, chemical industry, thermal power generation, and this is that China is with heavy chemical industry
The result of main economic growth, is also China's industrialization, the inevitable outcome of Development of Urbanization.
Boiler can occur various types of corrosion during operation and deactivation.Generally, boiler corrosion is divided into chemistry
Corrosion and electrochemical corrosion.Wherein, electrochemical corrosion is more conventional in boiler corrosion, and endangers larger.The feedwater of boiler is electricity
Xie Zhi, it is not complete in metal material chemical inequality, different institutional framework, deformation and internal stress heterogeneity and metal surface film
When whole, all many corrosion micro cells can be formed in metal surface, cause electrochemical corrosion.Oxygen common in production is rotten
Erosion, acid corrosion and underdeposit corrosion etc. belong to electrochemical corrosion.Boiler corrosion can not only shorten the service life of equipment, directly
The safe operation of influence boiler is connect, economic loss is caused, and the corrosion product of boiler can be entrained into steam turbine or other equipment,
And then have a strong impact on life-span and the safe operation of these equipment.
If the water containing calcium and magnesium hardness is directly entered in boiler without treatment, after operation a period of time, boiler water side is received
Some solid deposits, i.e. incrustation scale will be firmly attached on hot face.After gyp, the heat of fuel combustion can not be timely
Water side is delivered to, heating surface temperature is raised, if boiler heating surface is long-term being run under overtemperature state, metal material will occur compacted
Change, bulge, intensity decline, and cause quick-fried.If if the water pipe of boiler is blocked because of a large amount of foulings, it will booster occurs quickly.Pot
Stove booster one is seriously to jeopardize people's life and safety, and two is that can roll up cost of overhaul use after booster, and three is frequent start-stop pot
Stove can cause waste of fuel.
The problems such as boiler corrosion in solution production process and fouling, more preferable saving water resource, the use of extension device
Life-span, boiler corrosion inhibiting and descaling agent arises at the historic moment.In recent years, phosphorous organic inhibition dirty-proof agent is good with its chemical stability and collaboration is imitated
Should be preferable the advantages of and turn into the class water quality stabilizer being most widely used in Treatment of Industrial Water.But the discharge of phosphorus easily causes
Body eutrophication, breaks out the water quality events such as large area " red tide ", has a strong impact on ecological environment.Meanwhile, according to document announcement, currently
In the reagent combination of numerous boiler corrosion inhibiting and descaling agents that China uses, phosphorus system accounts for more than 50%, and the discharge of its treatment phosphor in sewage can
Can be considerably beyond the phosphate of first discharge standard requirement in China's integrated wastewater discharge standard（In terms of P）Discharge value.
The content of the invention
Goal of the invention：The present invention is for problem present in above-mentioned existing water treatment agent, there is provided one kind can effectively press down
