Abstract
The invention discloses an anti-descaling powder agent for medium low pressure boiler, which comprises the following steps: compositing with sodium carbonate and humic acid sodium; allocating 45-85 wt sodium carbonate and 15-25 wt humic acid; getting the product. This invention possesses merits as follow: collecting scale prevention and conservation as one body; forming a smooth protective film in the boiler; inhibiting corrosion of oxyhydrogen molecule; setting antiscaling ratio at 90% without toxic and pollution.
Description
Technical field
The present invention relates to a kind of antiscale, scale removal pulvis that is used for middle low-pressure boiler.
Background technology
Current industry and civilian aspect the extensive application boiler, wherein middle low-pressure boiler accounts for 2/3, high-duty boiler accounts for 1/3, to damage in boilers serious be scale problems, middle low-pressure boiler (comprising hot water boiler) particularly is after the gyp, influence heat transfer efficiency reduction of service life, wastes energy.In order to prevent gyp or to carry out scale removal, mostly adopt methods such as traditional soda ash method, sodium ion exchange process, electronics antiscale instrument, pickling 1 time at least in every boiler every year, the anti-scale removal effect of aforesaid method is all undesirable.
Summary of the invention
The objective of the invention is to provide in order to overcome the deficiencies in the prior art a kind of scale removal rapidly, be convenient to transport, prepare easy to use and be suitable for the anti-scale removal pulvis that middle low-pressure boiler uses.
Pulvis of the present invention mainly is made up of yellow soda ash, Sodium salts humic acids, and the weight proportion of each component is: 45～85 parts in yellow soda ash, 15～25 parts of humic acidss.
The present invention can also select in above-mentioned prescription and add Sodium hexametaphosphate 99, and the weight proportion of its component is: 60～80 parts in yellow soda ash, 15～20 parts of humic acidss, 5～10 parts of Sodium hexametaphosphate 99s.
The present invention can also select in above-mentioned prescription and add the phosphoric acid trisodium, and the weight proportion of its component is: 45～60 parts in yellow soda ash, 15～20 parts of humic acidss, 5～10 parts of Sodium hexametaphosphate 99s, 30～35 parts of tertiary sodium phosphates.
Only need make 25～35% the aqueous solution when using above-mentioned pulvis gets final product.
The present invention has following advantage: because this medicament collection antiscale, anticorrosion be one to stop, in body of heater, form a kind of slick protective membrane, hindered the hydrogen-oxygen molecule to corrosion of metal, antiscaling rate reaches more than 90%, scale removal is rapid, etching apparatus not, nontoxic pollution-free.
Embodiment (dosage is weight part)
Embodiment 1: 80 parts in yellow soda ash, 20 parts of Sodium salts humic acidss.
Embodiment 2: 85 parts in yellow soda ash, 15 parts of Sodium salts humic acidss.
Embodiment 3: 75 parts in yellow soda ash, 15 parts of Sodium salts humic acidss, 10 parts of Sodium hexametaphosphate 99s.
Embodiment 4: 65 parts in yellow soda ash, 15 parts of Sodium salts humic acidss, 5 parts of Sodium hexametaphosphate 99s.
Embodiment 5: 80 parts in yellow soda ash, 15 parts of Sodium salts humic acidss, 10 parts of Sodium hexametaphosphate 99s.
Embodiment 6: 50 parts in yellow soda ash, 20 parts of Sodium salts humic acidss, 10 parts of Sodium hexametaphosphate 99s, 30 parts of tertiary sodium phosphates.
Embodiment 7: 45 parts in yellow soda ash, 15 parts of Sodium salts humic acidss, 5 parts of Sodium hexametaphosphate 99s, 30 parts of tertiary sodium phosphates.
Embodiment 8: 60 parts in yellow soda ash, 15 parts of Sodium salts humic acidss, 8 parts of Sodium hexametaphosphate 99s, 35 parts of tertiary sodium phosphates.
Above-mentioned pulvis can now use existing preparation, and the preparation weight ratio is: pulvis accounts for 25～35%, and surplus is a water.
