Abstract
The invention relates to a dust deposition inhibitor for a dedusting water system in a steel plant, which is an ideal water treatment chemical which can be used for scale removal, scale inhibition and dust inhibition of the dedusting water system in the steel plant. The dust deposition inhibitor is a comprehensive multifunctional chemical scale removal, scale inhibition and dust inhibitor which takes materials such as polyphosphate, organic polymers and the like with good scale removal, scale inhibition and dispersing performance as main agents and materials such as inorganic salts, multiple additives and the like as assistants. The dust deposition inhibitor has good scale removal, scale inhibition and dust inhibition effects, and is free of hydrogen brittleness, corrosion, toxicity, smell and pollution. After the dust deposition inhibitor for the dedusting water system in the steel plant is used in the dedusting water system, the scale inhibition rate can reach 100 percent, the scale removal rate can reach 99.5 percent and the annular corrosion rate can reach 99.6 percent. When the dedusting water system after scale removal, scale inhibition and dust inhibition runs under a scale-free condition, the system is not required to be shutdown for cleaning and maintenance. Therefore, huge economic losses can be reduced and greater economic benefits can be obtained.
Description
Technical field
The present invention is that influence is produced and multifunctional chemical water conditioner that the scale removal, scale inhibition, the dust that provide suppress after the electrodeposition substance foulings such as a kind of dust that is used for the steelworks dust removing water system, calcium, magnesium.
Steelworks equipment dust removing water system is different through long-time running and feedwater treatment effect, the generation that inevitably can produce various impurity in the system, and in equipment high-temperature heating process, the surface can produce precipitation and form dirt within it, simultaneously the C in the water
a 2+, M
g 2+Isoionic salt is separated out with crystalline form during because of high temperature and is deposited on the metallic surface, forms fine and close hard incrustation scale.Therefore after equipment has accumulated dust, settling, hard scale and has reached certain amount, heat transfer efficiency descends, thermo-efficiency descends makes metal localized hyperthermia overheated easily, physical strength descends, when serious metal heated heat conductivility, pipe interior diameter diminish, congestion affects production.This brings loss with regard to needing regularly to remove incrustation scale, certainly will cause to stop production to production.Water conditioner of the present invention is when giving dust removing water system scale removal, scale inhibition, without blowing out, stopping production, wash at normal calcium, magnesium, silicon, iron dirt, the dust that is about to be accumulated in the dust removing water system in service of equipment.This has just guaranteed the normal operation and the ordinary production of equipment.In dust removing water system, allow it keep this certain invention water treatment agent.With regard to non flouling behaviour, it can play dirty scale removal, do not have the generation that dirt stops new dirt in the dust removing water system.The blowing out that just need not stop production has been cleaned.Use the YQ-301 steelworks dedusting pigment dirt sedimentation inhibitor of this invention, just can save blowing out cleaning charge usefulness, improve the security of efficiency of equipment and use.
Background technology
The technology of water conditioner is of a great variety now, as: methods such as ion exchange resin softening water method, Scale inhibitors and the pickling agent of physical method, certain disadvantage is all arranged, as: use the resin method, can only scale inhibition, can not scale removal, can not corrosion protection, investment is big, management is numerous again.The method of scale inhibition can only scale inhibition, can not scale removal, more single.The method of pickling is to very big, the fragile equipment of equipment corrosion, cause very big financial loss, reduce life-span of equipment.In addition, the aforesaid method price is also relatively more expensive.At above-mentioned deficiency, the invention provides that a kind of raw material is easy to get, the water treatment agent of low price, a kind of YQ-301 steelworks dust removing water system dust deposit inhibitor easy to use.For the inhibition of steelworks dust removing water system dust deposit, scale removal, scale inhibition, corrosion protection have split easily row of a letter, safe and reliable, effective again new way.
Technology of the present invention has the following advantages compared with prior art: production technique is simple, raw material is easily purchased, cost is low, high efficiency, nontoxic, tasteless, do not have a corrosion.It is effective soon to remove hard dirt (as carbonate, vitriol, silicate and mixture or the biological clay) speed of mixing knot under dirt and the high temperature.YQ-301 steelworks dust removing water system dust deposit inhibitor of the present invention for reach above-mentioned effect selection thionamic acid sodium, hydrolytic polymaleic anhydride, sodium polyacrylate, be main descaling, and blocking scaling agent.In order to add fast response and scale removal speed, composite certain tripoly phosphate sodium STPP, Sodium hexametaphosphate 99, to be dispersion agent.Select yellow soda ash, tertiary sodium phosphate for use in order to improve cleaning performance, be agent transition.Selected tensio-active agent OP-10 for use in order to strengthen osmosis.With the above-mentioned scale removal of purchasing, scale inhibition, dust inhibitor.Scale removal, scale inhibition, dust suppress that effect can reach, scale inhibition performance 100%, descaling rate 99.5%.

YQ-301 steelworks dust removing water system dust deposit inhibitor compound method of the present invention:
Earlier water is joined in the retort by formula ratio, start stirring, at leisure add sodium polyacrylate, treat to dissolve fully agranular transparence thick liquid, then slowly adding thionamic acid sodium, polymaleic anhydride, 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid sodium, stirring and dissolving fully after.Be sequentially added into yellow soda ash, tertiary sodium phosphate, tripoly phosphate sodium STPP, Sodium hexametaphosphate 99, OP-10.Stirring two hours is qualified product to dissolving the transparent thick liquid of no particle fully.
Embodiment
The YQ-301 steelworks dust removing water system dust deposit inhibitor that the present invention is prepared, have in the storage tank of annotating the plug pump with being pumped into, determine to add dose according to the water quality situation, to annotate the plug pump then reconciles by injection rate per hour, keep in equipment, offeing medicine uniformly in 24 hours, have all the time in the maintenance equipment like this in certain pharmaceutical quantities equipment just can not produce incrustation scale, dust deposit.
