Abstract
The invention provides a corrosion and scale inhibitor for a heat supply network. The corrosion and scale inhibitor contains deionized water, organophosphorus, sulfonate, sodium hydroxide and zinc salt in a ratio of (30-70):(10-40):(5-20):(10-30):(2-10). The corrosion and scale inhibitor is capable of effectively controlling corrosion and scaling of heat exchangers, relevant pipelines and the like of a steam or backwater system in the heat supply network.
Description
Technical field
The present invention relates to water treatment field, be specifically related to the medicament that a kind of heating network is used, relate in particular to a kind of heating network corrosion inhibiting and descaling agent.
Background technology
The hot water boiler of heating network all plays an important role in industrial production or people's lives.Yet the operation fouling of hot water boiler system, corrosion associated problem are to perplex for a long time people's a difficult problem.Because working conditions and the steam boiler of hot water boiler has a great difference, hot water boiler room is also simple and crude than boiler steam room, many effective technology of steam boiler is difficult to be suitable for to hot water boiler.The anti-corrosion, scale-inhibiting technology for hot water boiler of developing, some is ripe not enough, though some ripe application is still not general.These situations cause current hot water boiler corrosion very serious.Abroad, the not yet fine solution of this problem.General hot water boiler is used and just there will be afterwards obvious metallic corrosion phenomenon in 2 or three years, and red water or leakage occur, and corrosion phenomenon also very easily occurs the pipeline in its pipe network.The corrosion condition of China's hot water boiler system is even more serious.According to Liaoyang City, Liaoning Province survey of boiler institute, add up, in 800 heating boilers in use, the boiler that corrosion has occurred just has 755, accounts for 95%, wherein heavy corrosion accounts for 10%-15% corrosion leakage and accounts for 5%-8%, and the normal recondition expense of spending due to corrosion reaches nearly 1,000,000 yuan.Be 12 years the life of China's hot water boiler, due to reasons such as corrosion, only move 5～8 years and just scrapped, and be only 1/2～1/3 of life.
Corrosion can cause huge financial loss.Concerning hot water boiler and its pipe network, corrosion is except causing reducing the life-span, increasing considerably maintenance and overhaul cost, also due to corrosion leakage, often occurs in the winter heating period of severe cold, and confession thermal break can directly have influence on resident's orthobiosis.In order to change this present situation, research and development hot water boiler anti-corrosion, scale-inhibiting technology is imperative.
In order to prevent the operation fouling corrosion of heating network, for many years, people try hard to thermal de-aeration, deaeration in condenser etc. to refer on hot water boiler the effective technology of steam boiler, because hot water boiler room lacks implementation condition, do not have successfully.The Deadsorbing and oxygen removing of developing for hot water boiler specially, redox resin deoxygenation, Arbiso process, zinc-plate process etc. also exists many problems that wait solution.High dosage sodium nitrite method is in Japan's application of succeeding, but due to well-known toxicity problem and add quantity not sufficient and likely cause that Boiler Metallic pitting Er Mei other countries promote the use of.
Along with the quickening of China's urbanization and process of industrialization, with the closely-related Industrial Boiler of productive life and hot water boiler heating system scale also rapid growth.Due to the reasons 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 rising.
technical scheme
The object of the present invention is to provide a kind of heating network corrosion inhibiting and descaling agent, can effectively control the metal generation corrosion and scaling of the interchanger of hot water boiler water vapour or return water system and associated pipe etc.
The technical solution adopted in the present invention is as follows:
A heating network corrosion inhibiting and descaling agent, contains deionized water, organophosphorus, sulfonate, sodium hydroxide, zinc salt, and the weight percent of each component is:
Deionized water 30～70%
Organophosphorus 10～40%
Co-polymer of sulfonate 5～20%
Sodium hydroxide 10～30%
Zinc salt 2～10%
Described organophosphorus is 2-phosphate-1, one or more of 2,4-butane tricarboxylate, 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid, Amino Trimethylene Phosphonic Acid.
Described co-polymer of sulfonate is one or more of vinylformic acid-2-acrylamide-2-methylpro panesulfonic acid multipolymer, Sodium dodecylbenzene sulfonate, alkyl glyceryl ether sulfonate, lipid acid sulfoalkyl acid amides.
Described zinc salt be zinc sulfate, zinc chloride, zinc oxide one or more.
