Description
Technical field
The present invention relates to a kind of compound phosphate-free corrosion inhibition antisludging agent and application thereof.
Background technology
Along with the fast development of China's economic society, the imbalance between supply and demand of water is more outstanding, and shortage of water resources has become the important restraining factors of the sustainable development of socio-economy.Industrial enterprise is the rich and influential family of town water, and process water accounts for more than 60% of total water amount.The major part of process water is a recirculated cooling water, and cooling water amount can reach 85%～90% of total water amount.Therefore, the economized cycle water coolant is significant to industrial water saving, and improves the repeating utilization factor of water, promptly improves the recirculated cooling water cycles of concentration, is the effective way of economized cycle cooling water system water consumption.China is in water scarcity, and water resources utilizes problems such as mode is extensive, water use efficiency is not high, water waste still very outstanding.Compare with international most advanced level, per ten thousand dollars of GDP water consumptions of China in 2005 are 2500m
3, be about 3 times of world average level, be 5～10 times of international most advanced level; The ten thousand yuan of industrial added value water consumption 169m in the whole nation in 2005
3, be about 5～10 times of developed country.Contrasting above-mentioned data can find out, having a high potential of Industrial-Enterprises in China water saving shoulders heavy responsibilities.
Phosphorus line formulation since 20th century the mid-1970s be applied to now more than 30 year.Because phosphorus is the water conditioner low price and has good inhibition and scale-inhibiting properties, in water treatment, still accounts for absolute leading status at present.On the one hand; It has made huge positive contribution for the corrosion and the scale problems that solve the industrial cycle water system, can imagine, does not have polymerization phosphorus and organic phosphine to exist; Just do not have industrial cycle water system and production equipment safety long-term operation, phosphorus is that water conditioner has brought great riches to society.On the other hand, can bring a large amount of P contained compounds to trade effluent, cause unfriendly to environment because phosphorus is water conditioner; Although phosphorus is nontoxic; But as nutrition source, it makes body eutrophication, impels particularly algae excessive propagation of mikrobe; Cause harm such as lake water wawter bloom, red tide of sea, destroy the eubiosis.At present China is used for the nearly 100kt of phosphorus that corrosion inhibiting and descaling agent is produced every year, and these phosphorus compounds pollute environment finally as waste discharge, and strict control (discharge of wastewater primary standard P＜0.5mg/L) has made to the discharging of phosphorus in China for this reason.Can find out that phosphorus is the production of water conditioner prescription and uses and will be restricted, be that the water treatment agent prescription will progressively develop to low-phosphorous and no phosphatization as the phosphorus in one of source of phosphorus.China's industrial cycle water consumption is big, use phosphorus is that industries such as the more chemical industry of water conditioner, iron and steel, electric power, oil refining have been put into effect the regulation that reduces total phosphorous in the recirculated water successively.The implementation of the measure of " falling phosphorus " is polluted and is benefited reducing phosphorus certainly, and real development research and use the inevitable outcome that green phosphate-free corrosion inhibition antisludging agent is only Green Chemistry and environmental requirement.
