Description
Technical field
The present invention provides a kind of medicament that is used for preventing fouling of industrial circulating cooling water system burn into and microbial growth, relates to a kind of composite bactericidal corrosion inhibiting and descaling agent, belongs to Chemical Engineering water treatment agent production technical field.
Background technology
As the water rich and influential family, the development that petroleum industry is produced has consumed great amount of water resources.And at petroleum chemical industry, what water consumption was maximum is recirculated cooling water, accounts for the 80%-90% of industrial water.In today of water resource worsening shortages; Refinery(waste) water after the advanced treating is back to recirculating cooling water system; Be that the petroleum and petrochemical sector water saving subtracts dirty effective way; But the selection of water treatment agent is the bottleneck and the difficult point of practical application, and therefore developing the green product with multiple special efficacys such as sterilization, inhibition and scale inhibitions will have great economic benefit and social benefit.
Select water treatment agent corrosion inhibiter, antisludging agent, bactericide correct match to form the water treatment prescription to water quality, equipment material, the working condition of circulation; Confirm suitable process control condition; Carrying out the based process of recirculated cooling water handles with normal operation; The equipment such as cooling tower, cold water board that guarantee are in best running status; The corrosion of effective controlling microbial flora, the generation that suppresses incrustation scale, prevention pipe-line equipment, the recycling rate of waterused of raising industrial circulating cooling water is most important for the contradiction of alleviation and solution shortage of water resources and water resource waste.
In the middle of prior art; Water quality stabilizer as the industrial cycle cooling circulating water; Non-oxidizable bactericide of iso-thiazolinone in the common bactericide after microorganism contacts, can suppress its growth rapidly; And can penetrate the biomembrane that sticks to the water cooling equipment surface rapidly, the microorganism below the biomembrane is control effectively.The quaternary ammonium salt bactericide also generally uses, and circles such as Wang Jianna have been introduced the applicable cases of QS-14 bactericide in Qilu Petrochemical company, and this bactericide is formed by polyquaternium cationoid polymer and other bactericide and additive compound.Experimental result shows: when QS-14 concentration was 80～100mg/L, 4～24h was to heterotroph sterilizing rate >=98%, and had good glutinous mud stripping performance.
Phosphorus be antisludging agent modal be polyphosphonate and organic phospho acid.Polyphosphoric acid commonly used has sodium phosphate trimer and calgon, in water, generates the long-chain anion and is adsorbed on easily on the small calcium carbonate crystal grain, is both this anion and is easy to and CO3
2-Displacement, thus separating out of calcium carbonate prevented.
Poly-aspartate (PASP) has characteristics without phosphorus, nontoxic, pollution-free, excellent performance, has inhibition, scale inhibition dual-use function concurrently, is widely used in fields such as water treatment, and its related scientific research achievement has obtained U.S. Green Chemistry president prize and German Industrial prize.PASP has the linear polyimide amine structure, is the amino peptide that connects, and the amido link structure of analogous protein has excellent biological compatibility, can quick and complete degraded in environment, can not exert an influence to environment.Huo Yu coagulate to wait in " poly-aspartate and with the influence to the carbon steel corrosion inhibition of the compound of zinc salt "; Through composite; When obtaining poly-aspartate and acting on dosage separately and be 100mg/L; Corrosion inhibition rate reaches 80%, and under identical corrosion inhibition rate, only need add the poly-aspartate of 50mg/L when composite.It is thus clear that the pharmaceutical quantities of adding is very big, but effect is general.
But, remain in some problems in the existing technology.Water treatment agent is pointed, and effects such as sterilization, inhibition and scale inhibition can not exist simultaneously, and less to the scope of application of conditions such as pH, temperature, especially in petrochemical industry under the oil leak situation, and water treatment agent effective relatively poor.At present; For realizing that " zero-emission " carry out the reuse of recirculated cooling water, add water treatment agent after, whether the influence of water quality is existed the phenomenon of fluctuation; Be stability and the chemical breakdown property balance whether of water treatment agent, all there is certain influence in this to recirculating cooling water system.
Secondly, the monomer medicament is when each self-applying, and the cost that needs is higher.According to the synergy that possibly exist between each medicament; Medicament is carried out composite research; Make its function that reaches the potion multiple-effect, this also meet international advanced water treatment agent just trending towards high-effect, low toxicity is nuisanceless, the pollution-free industry direction Development Trend of multi-functional, compoundization.
