Abstract

The invention provides a scale preventing and removing agent, which comprises the following components in weight ratio as follows: 20% of Diethylenetriaminepenta, 10% of Nitrilotrimethylene Triphosphonic Acid, 30% of Bis(HexaMethylene Triamine Penta (Methylene Phosphonic Acid)), 20% of Flake Caustic Soda, 10% of an antirusting agent and 10% of fungicide. The production process of the scale preventing and removing agent is characterized in that the scale preventing and removing agent is formed in a mode that all components are stirred and mixed under the condition with temperature being 30 DEG C+/-1 DEG C and the PH being 11+/-0.5. The scale preventing and removing agent provided by the invention clears the water scales of a boiler water system under the condition that a boiler runs, and also can prevent the generation of novel scales.

Description

A kind of scale preventing and removing agent and production technique thereof
Technical field
The present invention relates to chemical field, medicament and the production technique thereof in especially a kind of boiler water circulation system stove, processed.
Background technology
Boiler is a kind of energy conversion, have the forms such as heat energy of chemical energy in fuel, electric energy, high-temperature flue gas, and through boiler conversion, outwards output has steam, high-temperature water or the organic heat carrier of certain heat energy to the energy of boiler input.The original meaning of pot refers to the water container heating on fire, and stove refers to the place of combustion fuel, and boiler comprises pot and stove two parts.The hot water producing in boiler or steam can be directly for industrial production and people's lives provide required heat energy, also can be converted to mechanical energy by steam power plant, or by generator, mechanical energy is converted to electric energy again.Provide the boiler of hot water to be called hot water boiler, be mainly used in life, in industrial production, also have a small amount of application.The boiler that produces steam is called steam boiler, often referred to as boiler, is used for thermal power station, boats and ships, locomotive and industrial and mining enterprises.
Because boiler is in the process of operation, can produce a lot of incrustation scales, the existence of these dirts, has sizable harm to boiler.First, waste fuel, reduction is exerted oneself.Easily cause accident, affect safe operation.In addition, meeting blocking pipe, destroys water cycle.Cause underdeposit corrosion, shorten boiler life.Meanwhile, after gyp, will increase time, expense and the workload etc. of cleaning and keeping in repair, impact is produced.Reduce boiler effective rate of utilization, reduce economy.
In order to prevent that boiler knot from scaling, guarantee safe and economical boiler operation, must strengthen boiler to water treatment, guarantee that feed water quality meets national standard.From the fifties, the water treatment agent that China is generally used is water-softening chemicals, water-softening chemicals can only part precipitation oiler feed in calcium, magnesium ion, can only slow down the formation of incrustation scale, effectively scale inhibition.
Summary of the invention
The problem to be solved in the present invention is to improve the problem of the antiscaling, descaling effectively of water-softening chemicals in background technology.
In order to overcome the above problems, the invention provides a kind of scale preventing and removing agent, each component of described scale preventing and removing agent and weight ratio thereof are as follows: diethylenetriamine five methenes 20%, Amino Trimethylene Phosphonic Acid 10%, two hexene triamine pentamethylene Alendronates 30%, sheet alkali 20%, rust-preventive agent 10%, sterilant 10%.
Described rust-preventive agent is mainly comprised of trolamine, sub-sodium.
A production technique for scale preventing and removing agent according to claim 1 and 2, each component of described scale preventing and removing agent is to be uniformly mixed and to form under 30 ℃ ± 1 ℃, the PH condition that is 11 ± 0.5 in temperature.
A kind of scale preventing and removing agent of the present invention, the performance of each component and effect are as follows: 1, high molecular polymer: diethylenetriamine five methenes, molecular formula: C 9h 23o 15n 3p 5na 5, nontoxic, be soluble in acidic solution, scale inhibitor effect is all good and temperature tolerance good, can suppress the generation of carbonate, sulfate scale, and under alkaline environment and high temperature, (more than 210 ℃) anticorrosion-antiscaling property is good compared with other organic phosphine.Relative molecular mass: 683.2.2, high molecular polymer auxiliary agent: Amino Trimethylene Phosphonic Acid, molecular formula: N (CH 2pO 3h 2) 3c, relative molecular mass: 299.05, good chelating, lower bound suppress and lattice distortion effect.Can stop the formation of scaling salt class formation incrustation scale, particularly calcium carbonate scale in water.Stable chemical nature in water, not facile hydrolysis.When concentration is higher in water, there is good corrosion mitigating effect.3, Polymeric complexes: two hexene triamine pentamethylene Alendronates, molecular formula: C 17h 44-Xo 15n 3p 5na x,relative molecular mass: approximately 731,
Be efficient chelating type Scale inhibitors, carbonate scale and sulfate scale are had to good scale inhibition effect.Under wider pH scope and 120 ℃ of high temperature, there is splendid water-soluble and thermostability, high to calcium ion tolerance.4, sheet alkali, sodium hydroxide solution, is the dissolving of chemical reaction.5, rust-preventive agent, trolamine, sub-sodium forms and stores one deck lubricant film on parts surface, can suppress the corrosion that water and many other Chemical Composition cause.6, sterilant, the Biocidal algae-killing agent that quaternary ammonium salt and isothiazolinone are combined into, there is efficient, wide spectrum, low toxicity, drug effect is fast and the advantages such as lasting, seepage force is strong, easy to use, applicable temperature and pH a wider range, life-time service can not make bacterium algae develop immunity to drugs.
Scale preventing and removing agent of the present invention, the in the situation that of not blowing out of boiler, removes the incrustation scale of boiler water system, prevents the generation of new dirt simultaneously.
