Description
Technical field
The invention belongs to drinking water chemical treatments field, it is related to novel environment-friendly solid anti-incrustation corrosion inhibitor, especially one
The modified scale inhibitor material producing method of kind and equipment.
Background technology
Currently, global water process business flourishes, Water Treatment Chemicals Market competition, and each relevant company is contention
The merger of market expansion merchandise very hot U.S. be global Water Treatment Chemicals maximum user, year the amount of consumption be about 30.6
Hundred million dollars.Latin America and Asian-Pacific area water treatment field are quickly grown, it is contemplated that Latin America's water process market will increase by 49% within 2015, reach
To 14.7 hundred million dollars, the Asian-Pacific area will increase by 23% (without China), reach 15.1 hundred million dollars.According to statistics, China's work in 2013
Industry water consumption is up to 150,000,000,000 tons, and urban domestic water is up to 25,000,000,000 tons.With this, it is expected that domestic water treatment agent annual requirement should be 220
More than ten thousand tons.The gross output value of China's water treatment agent is 4,700,000,000 dollars of RMB.
It is modern as national Eleventh Five-Year Plan outline clearly proposes " to build a resource-conserving and environment-friendly society "
China will continue the scale of investment of increasing pollution control and improvement of the ecological environment afterwards：2 years national environment protection total investments from now on
, about than Tenth Five-Year Plan Period increase by 64%, more than the 1.5% of same period GDP (GDP) will be accounted for up to 1,375,000,000,000 yuan；Input
Major fields mainly include water environment in terms of, in terms of atmospheric environment, in terms of solid waste, in terms of ecological environment, nuclear safety and
Radiation environment protection is built and environment capacity construction aspect.Water treatment agent is industrial water, domestic water, wastewater treatment process
The middle chemical agent that must be used.Current water process manufacturing enterprise of China is according to conservative estimation, every year in industrial circulating water system
At 13,000,000,000 yuan, emerging civil area is up to traditional antisludging agent sales volume to the demand of novel environment-friendly solid anti-scaling compound
130000000000 yuan or so, but such current solid anti-scaling compound is also in blank.In recent years, High-efficient Water of the China including antisludging agent
Processing product market is in the developing stage of high-speed expansion, and the market demand maintains average annual more than 30% growth rate and big
Import is measured, import volume is every year up to 2,000,000,000 dollars.With industrialized development, China will turn into a few years from now on and increase in the world
Most fast water treatment agent market.But the antisludging agent product home brands of existing market are few, technical merit is low, and due to using
The limitation of itself such as method, environmental-protecting performance, it is high low with treatment effeciency there is use and maintenance cost, it is poor for applicability the problems such as.
China, as the big country of an environmental resource consumption, the novel environment-friendly water treatment product for developing oneself is necessary.New type water
The technology that the preparation of processing product is crucial as one becomes the water process in China and an industrial big bottleneck, particularly
The safety applications of water resource have arrived the situation of very severe, and research and development China has the water treatment product of core technology by oneself
Having become for technology is very urgent.It is well known that incrustation scale is global problem.China major part region water quality is harder, knot
Dirt is than more serious.The thermal conductivity of incrustation scale is excessively poor, small tens times of its thermal conductivity ratio metal even hundreds of times.There is experiment to show to work as
After heat-exchange surface fouling, often increasing 1mm incrustation scales, then thermal conductivity factor will reduce 20%-30%, i.e. power consumption increase 20%-30%.
When scale forming reaches 12.7 millimeters, that will consume 70% energy more.It can be seen that from data above, incrustation scale is energy-saving society
Extremely discordant sound in meeting.More it is especially surprising that incrustation scale not only causes serious energy waste, also easily cause family expenses
Electrical equipment, kettle, water dispenser, aluminum pot, solar water heater, electric heater, thermos flask and Domestic heating stove, hotel boiler, confession
The local corrosions such as warm heating stove or even perforation are scrapped, and What is more makes the uneven heating of utensil and set off an explosion, and causes to can't bear to set
The consequence thought.According to data statistics of the world about professional person, economic loss accounts for GDP's caused by incrustation scale every year in the whole world
0.25%.And in China, although lacking specific statistics, expert generally estimates, should exceed well over world average level.So
And even if being calculated by 0.25%, annual economic loss is also quite surprising --- and by China GDP in 2013 it is 9.4 trillion dollars
Calculate, economic loss caused by fouling is up to 23,500,000,000 yuan of dollars.Beijing University of Technology is heat conduction reinforced heavy with the process energy conservation Ministry of Education
One paper in point laboratory points out that according to incompletely statistics, the heat exchanger Da Wantai that China scraps by corrosion and scaling every year is left
The right side, only steel just consume more than 50,000 tons, more than 200,000,000 yuan of direct economic loss.And counted according to national departments concerned, every year because of water
Parts caused by dirt scrap direct losses and are up to more than 10 hundred million yuan.
The country is directed to scale problems now, how effective fouling the problem of never have good solution.Typically adopt
With mechanical treatment and chemical pickling method.Mechanical treatment can not fundamentally scale removal, existing fouling is only passed through machinery side
Formula is removed most of.And the method for chemical pickling has damage to equipment, it is discharged can cause secondary pollution again.Therefore, research is opened
Sending one kind can be taken by people whenever and wherever possible, meet food-grade production standard, safe and nontoxic harmless, efficient scale production
Performance number obtains whole mankind's popularization and application.
The content of the invention
For above-mentioned technical problem, the technical problem to be solved in the present invention is：By to high-specific surface area environmental protection inorganic
Material modification, their surface potentials is changed, produce the light current effect of similar cation, and be grafted with scale inhibition effect
Group, the group produce anionic scale inhibition group after meeting water so that the mineral material of high-specific surface area is in very oligodynamical
In the case of, it is hundreds thousand of right just to possess, or even millions of to amphiprotic activity group, plays micro dissolve in and can be achieved with efficient scale
Purpose.Because its have slightly soluble in bioactive minerals matter itself possessed water, small molten limit characteristic, there is the antisludging agent slow
Slow dissolving, release, green, efficient scale feature.Thoroughly solve civilian scale inhibition field, use traditional antisludging agent institute band
The safety problem come, present invention also offers in a kind of full production technology link it is possible that secondary pollution Resolving probiems side
Case, devise a kind of modified scale inhibitor material producing method and equipment.
