Abstract
The present invention relates to an antiscale and anticorrosive cleaning agent for boilers and a preparation method thereof. After plants containing tannin (such as tea) are soaked by boiling water for a period of time, the soaking liquid is filtered for removing residues under the temperature between 70 and 80 DEG C. Then, sodium metaphosphate substances are added into the filtered liquid according to set component ratio. After the sodium metaphosphate substances are completely dissolved, sodium pyrophosphate is added according to the set component ratio. After the sodium pyrophosphate is dissolved and uniformly mixed, the mixed liquid is filtered. Thus, the antiscale and anticorrosive cleaning agent is prepared. Compared with the prior art, the present invention has the advantages that the present invention is used for boiler operation for long time; the present invention ensures no water scale formation in boilers, protects carbon steel against the oxidation corrosion caused by dissolved oxygen in water, and achieves the action of removing scale if scale exists and preventing scale if scale does not exist and corrosion; the present invention has convenient storage and use.
Description
Technical field:
The utility model relates to a kind of water treatment preparation, particularly boiler compounds, preservative and manufacturing using method thereof.
Background technology:
Disclosed as Chinese patent application " 90100592.4 ", existing boiler compounds, anti-corrosive detergent is by the sodium-metaphosphate salt, soda ash, the powdered composition that Weibull and unslaked lime are formed, during use, after water dissolves powdered composition, add plant ash and caustic soda, make mother liquor after the filtration, render in the feedwater by a certain percentage then, utilize substance reactions such as the calcium bicarbonate that contains in Ca (OH) 2 and the water and heavy carbonic magnesium to generate CaCO3 and Mg (OU) 2 throw outs, and magnesiumcarbonate, magnesium chloride generates calcium salt (CaCO3, CaCL2), and make the CO2 gas in the water form the CaCO3 precipitation, be mainly used in the hardness of calcium salt in the softening water after the soda ash in the medicament is water-soluble.Metaphosphate ion in the medicament and the ion in the Weibull can be respectively with water in hydrogen, chlorion reaction again with the Fe3O4 and the Fe2O3 reaction of wall, generate ferric tannate and tricresyl phosphate iron mixture at the boiler internal perisporium, this material has bigger density also evenly securely attached on the perisporium.Neither continuous thickening can prevent that again objectionable impurities is to the corrosion of wall in medicament and the water with the regenerated scale forming matter is bonding.This kind boiler compounds, though containing the overwhelming majority in the water separating substances of C element, anti-corrosive detergent comes out, and at boiler inner wall formation one deck good antiscale property rete, but because boiler compounds, contain a large amount of Ca2+ ions in the anti-corrosive detergent, water in the boiler is drawn airborne CO2 easily in working cycle, water in CO2 and the water and Ca2+ combine and generate Ca (HCO3) 2, Ca (HCO3) 2 at high temperature generates CaCO3 easily and is adsorbed on and forms incrustation scale on the boiler wall, be unfavorable for boiler compounds on the contrary, scale removal, in addition because above-mentioned preparation contains a large amount of unslaked lime, storage time is once long caking easily, and the difficult dissolving of above-mentioned preparation, therefore use very inconvenient.
Summary of the invention:
That goal of the invention of the present invention is to provide is that a kind of boiler of feeding long-play uses, can make boiler not scaling, prevent oxygen in water to the oxidation corrosion of carbon steel, reach dirty scale removal is arranged, do not have dirty antiscale, preservative activity, use and store boiler compounds, anti-corrosive detergent and manufacturing using method thereof easily.
Stove antiscale of the present invention, anti-corrosive detergent are to realize like this, mainly mix by sodium-metaphosphate salts substances, trisodium phosphate, tannin, wherein the content of tannin is 1-3 part, trisodium phosphate content is 1-3 part, the sodium-metaphosphate salts substances is 1-3 part, and three kinds of mixed potential of hydrogen of composition are neutral or alkaline.
Here, will make aqua after three kinds of materials mixing, with the convenient potential of hydrogen of regulating.
The manufacture method of boiler compounds of the present invention, anti-corrosive detergent is to realize like this, contain the plant of tannin after (as tealeaves) for some time with the boiling water immersion, filter cleaner under the 70-80 degree celsius temperature, add the sodium-metaphosphate salts substances by the composition ratio of setting then, add trisodium phosphate by the composition ratio of setting again after treating to dissolve fully, wait to dissolve and mix after-filtration, promptly make boiler compounds, anti-corrosive detergent.
The adjusting of boiler compounds, anti-corrosive detergent potential of hydrogen can be finished by the composition ratio of three kinds of materials, also can regulate by adding appropriate amount of NaOH.
During use; the per ton of boiler water adds this medicament 15-30 milliliter; utilize metal ions such as metaphosphoric acid sodium salt and calcium magnesium to generate metal ions generation huge legendary turtle compounds such as complex compound and trisodium phosphate and calcium magnesium and remove metal ions such as calcium magnesium in the water; prevent that it from high temperature resolving into calcium magnesium incrustation scale with the HO3-1 ion; simultaneously; utilize trisodium phosphate to disperse; the effect of scale removal and tannin penetrating quality are progressively separated incrustation scale and removing from boiler inner wall; utilize the rust cleaning performance of tannin and metaphosphoric acid sodium salt that the iron rust of boiler internal surface is removed then; utilize the oxygen uptake of tannin simultaneously and protect the steel surface of boiler internal to avoid oxidation corrosion in the water, may Yin Gaowen in the anti-sealing decompose by Ca (HCO3) 2 and the CaCO3 that produces is attached on and forms incrustation scale on the boiler inner wall at the formed ferric tannate protective membrane of steel surface.
The present invention compared with the prior art; owing to utilize the metaphosphoric acid sodium salt; trisodium phosphate is removed the calcium ions and magnesium ions in the water; like this; even contain the HCO3-1 ion in the water; can not produce incrustation scale yet; simultaneously; utilize the penetrating quality of tannin and the scale removal performance of trisodium phosphate step by step the incrustation scale in the boiler to be removed; then; utilize the derusting rust-proofing of metaphosphoric acid sodium salt and tannin and protect boiler inner wall to avoid the destruction of oxidation corrosion and incrustation scale with the protective membrane that iron ion generates; therefore, the present invention has the use of boiler of feeding long-play; can make not scaling of boiler; prevent the oxidation corrosion of oxygen in water to carbon steel; reach dirty scale removal is arranged; there is not dirty antiscale; preservative activity; store advantage easy to use.
