Abstract
The invention discloses a superhigh-temperature circulating water antisludging agent, which comprises phytic acid and polyamino polyether methylene phosphonae with the mass ratio of 1:1-20. The invention also discloses the application of the antisludging agent. The scaleinhibition capability of the antisludging agent is increased along with the temperature raise within the range of 100 DEG C, and has good scaleinhibition effect, realizes zero emission of sewage, greatly saves the circulating water, and can be applied to the difficult problems of water scaleinhibition for a blast furnace and continuous casting in a steel mill. By adopting the method of the invention to treat the high-temperature circulating water, the scaleinhibition effect is good, and the use level of the circulating water is greatly reduced.
Description
Technical field
The present invention relates to a kind of water conditioner, particularly a kind of high density circulating water antisludging agent that under high-temperature condition, uses.
Background technology
Recirculated water can occur some throw outs in operation after for some time, these throw outs can reduce water coolant cooling performance, cause underdeposit corrosion, influence the equipment operating performance.If regularly recirculated water equipment is handled, not only influence job schedule, and also need extra manpower and materials, strengthen cost.Therefore, the recirculated water antiscale is extremely important.Now, the general mode that adds Scale inhibitors that adopts stops incrustation scale to produce, and Scale inhibitors is to prevent that incrustation scale and dirt from producing or suppressing the chemical agent of its precipitation growth, and the adding of Scale inhibitors has been saved a large amount of water sources, also reduced cost, and industrial applicibility is strong.But conventional Scale inhibitors general provision in fresh water recirculated water uses is no more than 50 ℃, because after temperature was higher than 50 ℃, the scale inhibition ability of Scale inhibitors in recirculated water reduced along with the rising of temperature, may lose the scale inhibition ability when temperature is too high.Therefore, Scale inhibitors commonly used does not reach the purpose of the water saving of highly enriched recirculated water and scale inhibition under the high-temperature condition.
Summary of the invention
The present invention is in order to overcome the deficiency of above technology, a kind of superhigh-temperature circulating water antisludging agent is provided, this Scale inhibitors strengthens with the rising scale inhibition effect of temperature, can run well in interior recirculated water system at 100 ℃, scale inhibition effect is good, has solved the difficult problem at China's high temperature circulation water fouling and waste water source.
The present invention also provides the application of this Scale inhibitors in high temperature circulation water.
The present invention is achieved by the following measures:
It is best that national regulation, circulating water antisludging agent can only use in smaller or equal to 50 ℃, and when temperature surpasses 50 ℃, Scale inhibitors can decompose gradually, and scale inhibition effect lowers gradually with the rising of temperature, until disappearance.The inventor is through exploring and research, obtained a kind ofly at high temperature (80 ℃) scale inhibition ability good Scale inhibitors still down, and this Scale inhibitors patent No. is 200810013746.0, is lower than 80 ℃ hot environment but this Scale inhibitors only is applicable to temperature.The contriver has obtained enough effective Scale inhibitors under ultrahigh-temperature (100 ℃) environment after further study, and said here ultrahigh-temperature is meant the running environment of Scale inhibitors in 100 ℃, and is ultrahigh-temperature than national regulation smaller or equal to 50 ℃.
Concrete technical scheme is as follows:
A kind of superhigh-temperature circulating water antisludging agent comprises: hexalin six phosphoric acid ester and polyamino polyether methylene phosphonic acids, wherein, hexalin six phosphoric acid ester and polyamino polyether methylene phosphonic mass ratio are 1:(1-20).
Above-mentioned superhigh-temperature circulating water antisludging agent, hexalin six phosphoric acid ester and polyamino polyether methylene phosphonic mass ratio are preferably 1:(1-10).
The application of above-mentioned superhigh-temperature circulating water antisludging agent is characterized in that: this superhigh-temperature circulating water antisludging agent is joined in the recirculated water, and add-on is 2-20mg/L.
The condition of water quality that this superhigh-temperature circulating water antisludging agent is suitable for is: pH6-9, basicity 6-12, and temperature≤100 ℃, moisturizing hardness is not limit, concentration rate≤10.
Hexalin six phosphoric acid ester that the present invention is used and polyamino polyether methylene phosphonic acids can both have been bought in market.Wherein, hexalin six phosphoric acid ester are six phosphate ester of cyclohexanhexanol, myo-Inositol hexaphosphate again, and its structural formula is:
Polyamino polyether methylene phosphonic structural formula is:
n=2-12。
High temperature Scale inhibitors of the present invention is with hexalin six phosphoric acid ester and composite the forming of polyamino polyether methylene phosphonic acids, and they are macromolecular compound, is difficult for during high temperature decomposing, and stability is strong.Particularly the hexalin six phosphoric acid ester scale inhibition ability when high temperature in the prescription is stronger, calcium ions and magnesium ions combination in its main and water, generate the organic polymer calcium magnesium salts of non-scaling, reduced the scale-forming ions such as calcium ions and magnesium ions in the recirculated water, thereby reached the purpose of non-scaling; Polyamino polyether methylene phosphonic acids plays the effect of dispersion and inhibition.After these two kinds of macromolecular compounds are composite, both synergies, formed Scale inhibitors scale inhibition effect is good, and Scale inhibitors in 100 ℃ of scopes with the rising scale inhibition ability of temperature also along with rising, significantly different with common Scale inhibitors.Therefore, this Scale inhibitors is specially adapted to ultrahigh-temperature (in 100 ℃ of scopes) recirculated water system.In addition, this Scale inhibitors can make concentration rate reach about 10 times, realizes the zero release of sewage substantially.
Beneficial effect:
Scale inhibitors of the present invention, high temperature is difficult for decomposing, stability is strong, in 100 ℃ of scopes with the rising scale inhibition ability of temperature also along with rising, scale inhibition effect is good, reduce the blowdown flow rate of recirculated water, saved the recirculated water consumption greatly, solved the difficult problem at China's metallurgy industry high temperature circulation water fouling and waste water source.
The Scale inhibitors phosphorus content is low, and is big in temperature, hardness, PH scope, and running reaches good treatment effect as usual under the conditions such as concentration rate height, realizes the zero release of sewage.
Blast furnace, connection casting, electricity that the present invention can be used in the steel mill are on the point of high temperature recirculated water equipment such as cabinet, induction coil, have solved a scale inhibition difficult problem that is perplexing China's steel industry high temperature circulation water, also can be used for the high temperature circulation wetting system of other industry.
Use method of the present invention that high temperature circulation water is handled, scale inhibition effect is good, and the recirculated water consumption significantly reduces.
