Description
Technical field
The present invention relates to a kind of demineralized water water treatment agent and its preparation method and application, belong to water treatment neckTerritory.
Background technology
Most of natural water of the northern area of China belongs to middle high-hardness water, and the feature of this class water is calcium hardnessHeight, total alkalinity is high, and the corrosion tendency of water body is little, and fouling tendency is larger. The higher water of these hardness is through addingHeat is boiled, and calcium ion, the bicarbonate ion wherein containing can change into taking calcium carbonate as main cotton-shaped, powderShape sediment, is deposited on container, pipe surface formation incrustation scale. Once scale formation occurs, the deposition of incrustation scale is rightNormal life is produced and is brought many adverse effects, such as natural gas power unit water-cooling circulating system, with natureOnce there is fouling in the product wetting system that water is former water and various boiler, not only can greatly reduce heat transfer efficiency, resistanceFill in normal water flowing, affect equipment operating efficiency, even can bring potential safety hazard, threaten and destroy factory's long periodGround safety in production, causes economic loss.
For the problems referred to above, conventionally need to be to carrying out antiscale using natural water as the equipment of producing water or cycling use of waterProcess, conventional antiscaling method is chemical method, Physical and Process. In various inhibition and the side of slowing down foulingIn method, chemical scale-inhibiting has advantages of that cost is low, successful, thereby is generally adopted both at home and abroad.
Chemical method antiscale mechanism is to utilize some characteristic of chemical scale-inhibiting agent to stop the generation of incrustation scale. By to naturalIn water, add special antisludging agent, change the characteristic that calcium ions and magnesium ions is combined with carbanion, thereby slow down incrustation scaleSeparate out and deposit. At present, on market, common antisludging agent has natural polymer antisludging agent, phosphorous polymer scale inhibitionAgent etc. But natural polymer medicament exists consumption large, the problem that expense is high, and can not containing Phosphorus antisludging agentEffectively suppress calcium phosphate and zinc dirt and solve iron oxide precipitation problem, and processing to high rigidity natural waterEfficiency is on the low side.
Summary of the invention
For the deficiencies in the prior art, applicant has invented a kind of water treatment agent by research for many years, to containing calciumThe common high-hardness water of ion, magnesium ion etc. has good bating effect, is applicable to get Natural Water as lifeProduce factory and all kinds of boiler of water or cycling use of water.
Specifically, the present invention is achieved through the following technical solutions:
A kind of demineralized water water treatment agent, is made up of following three kinds of components, taking mass fraction: A component is as sulphurAcid 15-25 part, naphthalene 10-15 part; B component is triethanolamine 30-45 part, water 20-40 part; C component isGlucose 3-8 part, calgon 2-5 part, sodium metasilicate 0.5-2 part, sodium formate 0.1-0.5 part.
Preferably, the consumption of each component is that A component is 20 parts, sulfuric acid, 13 parts of naphthalenes; B component is triethanolamine36 parts, 30 parts, water; C component is 5.5 parts of glucose, 3.6 parts of calgons, and 1.2 parts of sodium metasilicates,0.2 part of sodium formate.
After water treatment agent of the present invention joins in the common hard water that contains calcium ion, magnesium ion etc., with calcium fromSon, the quick chelating of magnesium ion, thus calcium ion, the magnesium ion content in water reduced rapidly, make water demineralization.
Accordingly, the invention discloses the preparation method of above-mentioned demineralized water water treatment agent, comprise the steps:1) naphthalene is joined in sulfuric acid, stir until naphthalene dissolves completely at 48-52 DEG C, be then warming up to 70-75 DEG C insteadShould obtain brown transparency liquid; 2) join step 1 after triethanolamine and water are stirred) gained brownTransparency liquid, continues reaction at 70-75 DEG C, after reaction finishes, is cooled to 40-45 DEG C; 3) by glucose, sixSodium metaphosphate, sodium metasilicate, sodium formate join in the liquid that above-mentioned reaction finishes and are stirred to and obtain pale red brownTransparency liquid, is demineralized water water treatment agent.
In above-mentioned, in order to improve the adequacy of reaction, reduce wastage of material, step 1) be below 50 DEG CIn sulfuric acid, slowly add naphthalene. Refer in a long time naphthalene is evenly joined to sulphur used herein slowly addingIn acid, conventionally the adition process time used is in half an hour and longer, for example 1 hour.
Same, in order to ensure step 2) sufficient reacting carries out, and reduces wastage of material, step 2) at 70-75 DEG CContinue to react at least half an hour and longer, for example 1 hour.
Finally, the invention also discloses described demineralized water water treatment agent at softening calcium ions and/or magnesium ionApplication in hard water.
When for such use, can regulate according to the content of calcium ions and magnesium ions in hard water the consumption of water treatment agent;According to the content (200-2000mg/L) of two kinds of ions in common hard water, water treatment agent of the present invention with respect toThe consumption of water is 1-15g/L.
