Description
Technical field
The application belongs to environmental protection reagent process field, particularly relates to a kind of environmental protection, water-treating antisludging agent of boiler that corrosion inhibition is good and preparation method thereof.
Background technology
Scale inhibitors (scaleinhibitor): be the insoluble inorganic salt had in energy disperse water, prevention or the precipitation of interference insoluble inorganic salt in metallic surface, fouling function, and maintain the class medicament that hardware has good heat-transfer effect.Cold exchange device antiseptic corrosion inhibitor is with epoxy resin and specific amino resin for base-material, and it is formulated to add the appropriate various auxiliary agent such as various antirust, anticorrosion, is single component.It has excellent shielding, impervious, rustless property, good scale inhibition, thermal conductivity, the performances such as excellent weak acid resistant, highly basic, organic solvent, its strong adhesion, and rete is bright, pliable and tough, fine and close, hard.
The result of dissemination stops into dirt interparticlely contact with each other and condense, thus can stop the growth of dirt.Becoming dirty particle can be calcium, magnesium ion, can also be dust, silt or other water-insolubles.Dispersion agent is the polymkeric substance with certain relative molecular mass (or polymerization degree), and the height of dispersing property is closely related with the size of relative molecular mass (or polymerization degree).The polymerization degree is too low, then few by absorption divided particles number, dispersion efficiency is low; The polymerization degree is too high, then too much by absorption divided particles number, water body becomes muddy, even forms flco (effect is now close with flocculation agent).Compared with sequestering action, dissemination is efficient.In middle high hardness water, the divergent function of Scale inhibitors plays a major role.
Hot water boiler all plays an important role in industrial production or people's lives.But the operation burn into withdrawal hepatitis of hot water boiler system and the corrosion product scale problems caused therefrom are but long-standing problem people's difficult problems.Because the working conditions of hot water boiler and steam boiler have a great difference, hot water boiler room is also simple and crude than boiler steam room, is manyly difficult to be suitable for hot water boiler to the effective technology of steam boiler.The anti-corrosion, scale-inhibiting technology for hot water boiler developed, some is ripe not enough, though some ripe application is still not general.It is very serious that these situations cause current hot water boiler to corrode.Abroad, this problem solves not yet very well.General hot water boiler uses 2 or three years and just there will be obvious metallic corrosion phenomenon afterwards, and red water or leakage occur.The corrosion condition of China's hot water boiler is even more serious.Add up according to survey of boiler institute of Liaoyang City of Liaoning Province, 800 heating boilers in, the boiler that there occurs corrosion just has 755, accounts for 95%, wherein heavy corrosion accounts for 10%-15% corrosion leakage and accounts for 5%-8%, and due to corrosion, the normal service expense of flower reaches nearly 1,000,000 yuan.The life of China's hot water boiler is 12 years, due to reasons such as corrosion, only runs and has just scrapped for 5 ~ 8 years, be only 1/2 ~ 1/3 of life.
Corrosion can cause huge financial loss.Concerning hot water boiler, corrode except causing reducing the life-span, increasing considerably except maintenance and overhaul cost, also because corrosion leakage often occurs in the winter heating period of most severe cold, directly can have influence on the orthobiosis of resident for thermal break.In order to change this present situation, research and development hot water boiler anti-corrosion, scale-inhibiting technology is imperative.Hot water boiler corrosion and serious present situation thereof were both corroded relevant, also relevant with withdrawal hepatitis with operation.
In order to prevent the operation of hot water boiler from corroding, for many years, people try hard to thermal de-aeration, deaeration in condenser etc. to refer on hot water boiler to the effective technology of steam boiler, do not have success because hot water boiler room lacks implementation condition.Be the Deadsorbing and oxygen removing of hot water boiler exploitation specially, redox resin deoxygenation, Arbiso process, zinc-plate process etc. also also exist many problems waiting to solve.High dosage sodium nitrite method to be succeeded application in Japan, but due to well-known toxicity problem and add quantity not sufficient and likely cause Boiler Metallic pitting and do not promote the use of in other countries.
Corrosion between boiler lay-off period is even more serious than running corrosion, and large-scale corrosion damage and local corrosion failure are often caused by withdrawal hepatitis.The hot water boiler system operating period is short, and lay-off period is long.The red water caused by withdrawal hepatitis and leakage accident occur again and again.For preventing and alleviating withdrawal hepatitis, developed some guard methods, main method is traditional dry method and wet method and the successful TH-901 method of research.Under the strict condition implemented, the effect that conventional dry and wet method also can obtain, but because operated in accordance with conventional methods is loaded down with trivial details, the medium small boiler room often incomplete reason such as qualified to exploit, effect is very undesirable.TH-901 method efficiently facilitates, and the protection period is long, generally applies in the whole nation; successful beyond doubt to the protection of boiler body, but, to the complex grid of hot water boiler system; heat exchanger and spread all over the scatterer of huge numbers of families, is difficult to protection owing to cannot place TH-901 inhibiter.Because the envrionment conditions during boiler operatiopn and between lay-off period is widely different, operation corrosion and withdrawal hepatitis have the reasons such as the technical problem waiting to solve, both at home and abroad for research, the development and application of hot water boiler anti-corrosion, scale-inhibiting, or for boiler operation, or for inactive boiler, the operation of boiler and both separately process of stopping using--adopt a set of technology anti-corrosion, scale-inhibiting during operation, time inactive, adopt the anticorrosion maintenance of another set of technology to become traditional mode.Therefore, the hot water boiler total system Shut-down Protection method that research effect is good and simple and easy to do is very necessary.
Along with the quickening of China's urbanization and process of industrialization, also increase fast with the closely-related Industrial Boiler of productive life and hot water boiler heating system scale.Due to the reason such as restriction of boiler water processing state of the art, Industrial Boiler ubiquity corrosion and scaling problem, causes boiler life to shorten, and safeguards and running cost rises.And universal along with humanity concept, and the formation of novel harmonious society, designs a kind of nontoxic, odorless, environmental protection and good water-treating antisludging agent of boiler of corrosion inhibition and preparation method thereof is very important.
