Abstract
The present invention is natural phant, mineral type boiler scale cleaning agent, be with herbal medicine, natural phant and mineral are the compound pulvis of main raw material through being processed into, incrustation scale is produced the effect of dissolving, neutralizing, peeling off, and nontoxic, nothing erosion, safe and reliable, easy and simple to handle, can be widely used in various model boilers at the normal removing incrustation scale in service of boiler.
Description
The invention belongs to the clean the boiler technology.
At present, the chemical cleaning method of boiler generally takes to add the phosphoric acid trisodium in boiler, sodium hydroxide, and medicaments such as yellow soda ash or tannin extract also have the method that adopts pickling, and these methods not only need stop production and carry out, and operation easier is big, and are dangerous, and it is expensive to take a lot of work.
The objective of the invention is to develop a kind of new natural phant that utilizes, the compound scale remover of mineral, it is features high scale-removing effect not only, and nontoxic, pollution-free, easy and simple to handle.Can accomplish boiler scale removal while moving, the province that spends, and can take into account antiscale, rust cleaning, antirust function.
The objective of the invention is to adopt following scheme to realize: to contain alkali and tannin, starch and Mierocrystalline cellulose thereby incrustation scale is had dissolving, neutralization, adsorbing herbal medicine with employing, natural phant and mineral substance are main raw material, mix suitable industrial chemicals fermentation, through selecting materials, dry, pulverize, sieve, complete processing such as dosing stirring, make compound scale remover.
Utilize one embodiment of the present of invention that technical scheme of the present invention is elaborated below.Scale remover main raw material of the present invention and proportion following (in weight %): Turkey-galls 10～20%, cyrtomium fortunei 0～20%, starch 5～15%, sepiolite 3～10%, medical stone 10～20%, talcum powder 5～15, citric acid 0.5～2%, formaldehyde 0.5～2%, hydrochloric acid 4～12%, graphite 4～12%, salt 8～15%.After selecting materials, with conventional method drying, pulverize, sieve, dosing, mixing stirring, production technique such as pack, finish the production of scale remover.
In the above-described embodiments, Turkey-galls, cyrtomium fortunei contain alkali and tannin, and to silicate, irony incrustation scales such as vitriol have dissolving and disinfection under comparatively high temps.Destroy dirt layer structure, loose coming off.Starch cellulose and alkali sugar have above-mentioned solvency action to carbonate deposit.And has a adsorption to fine particle.Sepiolite, wheat flag in can planar water calcium, magnesium ion and have disinfection.Talcum powder and graphite have lubricated and peel off incrustation scale, and objectionable impurities improves the effect of vapor quality in the planar water; Citric acid and hydrochloric acid can promote the scale remover fermentation objectionable impurities in the soft absorption incrustation scale that fluffs.Formaldehyde has freshening effect to scale remover, and forms film with some organic acids and metallic iron, plays the boiler rust inhibition.Salt plays reduction and regeneration to scale remover.
Boiler detergent of the present invention, being widely used in various different shaped is to use on the boiler, when the thick 2～3mm of the dirt left and right sides, presses 3～4 kilograms of every steaming ton dosings every day under boiler does not stop production. When the incrustation scale of boiler, when soft water does not reach the boiler feed water index, also can add in right amount scale preventative of the present invention, concrete every day, 1 dose of medicine was 1 kilogram of every steaming ton in addition. General descaling and antiscaling fate is about 8～12 days, and every day, periodical blowdown can reach scale removal of the present invention, antiscaling effect. Its effect reaches more than 90%, and the boiler energy consumption is significantly descended, and saves comprehensive cost more than 50%, particularly power plant boiler scale removal and the scale removal of generator impeller sheet is had specific action. This scale remover scale removal ability is strong, and antiscaling effect is good, and nontoxic nothing erosion is safe and reliable, easy and simple to handle. Compare with the acid wash stain eliminating technology, significant economic technology benefit is arranged.
Use scale remover of the present invention, the water quality indices is as follows after tested later in scale removal:
Turbidity＜5 ° degree, tasteless, do not contain the naked eyes visible, pH value 6.5～8.5, total hardness 7.85, iron content 0.06%, vitriol 5.0%, muriate 0.71%, oxide compound 0.002%, plumbous≤0.01%.
Close in national standard fully with its water quality of the inventive method scale removal result as can be seen from above test.Than acid scale removal, have bigger superiority through testing identity the inventive method, see attached list 1 in detail.
