Description
Technical field
The present invention relates to a kind of green inhibition scale remover formula and application of sea water desalinating plant, in order to prevent the key metallic components such as aluminium flavones, 316L stainless steel and titanium alloy in the vaporizer of sea water desalinating plant and condenser unnecessary general corrosion and local corrosion in pickling descaling process.In addition, this formula also can be applied to metal and the corrosion of Fourier Series expansion technique in industrial acid-washed process thereof such as aluminium flavones, 316L stainless steel, titanium alloy, is belonging to industry cleaning link technical field.
Background technology
Hot method desalination technology is one of two large mainstream technologys of current sea water desaltination, its technology maturation, loose to influent quality requirement, but one of subject matter that fouling is the hot method sea water desalinating plant of puzzlement to be moved.Dirt covering metal surface can cause underdeposit corrosion, and corrosion product can form dirt, and the two promotes mutually, and the safe operation of system is brought to very big harm.Once heat-transfer surface forms dirt, can greatly reduce its heat transfer efficiency, increase resistance to flow, cause loss and the waste of the energy; Once and corrosion occurs, can cause interchanger seepage, affect the safe operation of production equipment.Therefore, need regularly to sea water desaltination key device, carry out scale removal cleaning, the research and development of distillation seawater desalination special descaling, Scale inhibitors, for forming China sea water desaltination complete set technology, to accelerate its industrialization paces significant.
In industrial scale removal process, conventional dilute sulphuric acid or dilute hydrochloric acid carry out pickling, can remove surperficial dirt layer, oxide film or corrosion product, for fear of the generation that consumes and prevent harmful corrosion excessively of metal in acid cleaning process or acid, in acid, adding inhibiter is effective means.
In at present conventional restrainer, mainly comprise the inorganic inhibition compound containing poisonous chromate, and some organophosphor compounds, its discharge may cause the eutrophication of water body.The inhibiter of existing same domain mostly has toxic side effect, does not possess the market competitiveness.Therefore, develop new environmental protection, cheapness, wide material sources, non-harmful restrainer is the new direction of current inhibiter exploitation.
Summary of the invention
The object of the present invention is to provide a kind of green inhibition scale remover and application thereof of sea water desalinating plant, in order to prevent unnecessary general corrosion and the local corrosion in pickling descaling process of the key metallic components such as aluminium flavones, 316L stainless steel and titanium alloy in the vaporizer of sea water desalinating plant and condenser.
Technical scheme of the present invention is: a kind of green inhibition scale remover of sea water desalinating plant, its main component is vitamin B3 and adenine phosphate.Two kinds of materials all belong to natural complex material, can from crude substance, extract in a large number, and be the material that can not lack in human body, be widely used in pharmacology, nontoxic.Vitamin B3 is a kind of water-soluble vitamins, rich content in fruits and vegetables, from yeast, liver, beast bird meat, in leaf vegetables, all can extract, can be used for antipellagra, also can be used as blood expansion medicine, be used as in a large number the additive of food and feed, as medicine intermediate, for vazadrine, niacinamide, Buddhist nun, can stop and the production of Vasonicit etc.Adenine phosphate is mainly present in the foods such as tealeaves and sugar beet juice, belong to niacin and the riboflavin of B group's VITAMIN, it is the moiety of nucleic acid, participate in the synthetic of genetic material, can promote leucocyte hyperplasia, white corpuscle number be increased, the leukopenia causing for preventing and treating a variety of causes, the leukopenia causing during especially for tumor chemical therapy, also for acute granulocytopenia.Vitamin B3 and adenine phosphate are mixed with the compound proportion of 1:1-5:1, and as the main ingredient of inhibiter in clean-out system, adding density of corrosion inhibitor scope is 0.01kg/m
3-0.20kg/m
3; And the pickle solution that clean-out system is used is dilute hydrochloric acid or dilute sulphuric acid, its concentration is 0.1mol/L-2.0mol/L; Pickling temperature remains on 25 ℃ of left and right; Add metal to be cleaned, submergence 0.5h-3h.
Principle of the present invention is: vitamin B3 and adenine phosphate molecule are the macrocylc compound with heterocycle, molecule contains atom or the atomic groups such as heterocycle, nitrogen, oxygen, sulphur, can effectively be adsorbed on aluminium flavones, 316L stainless steel and titanium alloy surface, play corrosion inhibition.
The invention has the beneficial effects as follows:
(1) vitamin B3 of the present invention and adenine phosphate wide material sources, market quotes in 2013: vitamin B3 be 50-100 unit/kilogram, adenine phosphate be 100-200 unit/kilogram, cost is very low.
(2) inhibiter of the present invention is crude substance extract, is nontoxic green matter, compared with the inhibiter of current chemosynthesis, there is not the environmental problem after use, harmless to environment and biological nontoxic, meet the trend that restrainer develops, have a good application prospect.
(3) the green inhibition scale remover of the present invention is applicable to the scale removal cleaning of seawater desalination evaporators and condenser or the inhibition pickling of aluminium flavones, 316L stainless steel and titanium alloy and Fourier Series expansion technique thereof, can effectively suppress the harmful corrosion in acid of above-mentioned various metal or its Fourier Series expansion technique, with at present conventional restrainer comparison, there is environmental protection, consumption is low, inhibition efficiency is high, and the outstanding advantages that continuous action ability is strong can Reusability.
