Description
Technical field
A kind of open type recirculated cooling water method for treating water, belongs to recirculated cooling water water-treatment technology field.
Background technology
Open type recirculated cooling water is recycled for a long time, and brings deposit attachment, metal erosion and microbial growth these three problem.Usually making iron concentration increase because of metal erosion in recirculated water, the impact of the antiscaling dispersion effect of dissimilar water treatment agent is determined by several factors.Open type circulating water cooling treatment mainly uses the method for dosing, i.e. adds dispersant, corrosion inhibiting and descaling agent, Biocidal algae-killing agent etc. in recirculated cooling water to reach to prevent the purpose of fouling, metal erosion and microbial growth.This method has certain effect, but long-term chemical feeding quantity is relatively big, causes environmental pollution and waste relatively big, and, the corpse of the microorganism after sterilization algae removal and the blocking of foundry loam also can increase the weight of.Simple dosing necessarily causes the raising of the concentration rate of recirculated cooling water, certainly will increase the blowdown flow rate of system and the magnitude of recruitment of fresh water.Dosing the most temporarily shields the harm of recirculated water, and processes solution the most thoroughly.
Antisludging agent and composite slow-corrosion scale resistor in use still lack systematic research to resistance calcium carbonate and the scale inhibition and dispersion performance influence factor of calcium phosphate, show same medicament and differ greatly in different circulations or at the treatment effect in period that same circulation is different.Medicament self concentration is one of factor of appreciable impact antiscaling dispersion effect.Hard and the increase of basicity with calcium, antiscaling dispersion effect declines.Calcium is hard and basicity is huge to medicament resistance calcium carbonate and resistance calcium phosphate function influence.Open recirling cooling water system is when processing high rigidity recirculated cooling water at present, and general calcium firmly adds basicity and controls 1200 ~ 1300
, if exceeding this index, easily there is scale problems in below mg/L；And, adding sulfuric acid treatment scheme even if using, calcium adds basicity firmly to be also difficult to more than 1400
mg/L.This recycling rate of waterused resulting in open type recirculated cooling water is low, needs often to supplement fresh water, causes water resource waste quantity of wastewater effluent simultaneously to increase.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, it is provided that the recycling rate of waterused of a kind of recirculated cooling water is high, saves fresh water, reduces water consumption rate, reduces the open type recirculated cooling water method for treating water of blowdown flow rate.
The technical solution adopted for the present invention to solve the technical problems is: this open type recirculated cooling water method for treating water, and being embodied as step is:
1) first to originally in alkaline recirculating cooling water system adding sulphuric acid to control the pH value of water to 7.6 ~ 9.1；
2) in recirculated cooling water, 18 ~ 39:10.5 ~ 18.6 are separately added into Part I anti-incrustation corrosion inhibitor and Part II anti-incrustation corrosion inhibitor in mass ratio；The each component of Part I anti-incrustation corrosion inhibitor relative to the valid density of pending circulating cooling water inventory is: organophosphor 2
Mg/L ~ 20mg/L, phosphine carboxylic acid 1 mg/L ~ 10mg/L, containing carboxyl and sulfonic copolymer 6mg/L ~ 18mg/L, each component of Part II anti-incrustation corrosion inhibitor relative to the valid density of pending circulating cooling water inventory is: zinc salt 0.2
Mg/L ~ 2.5mg/L, co-polymer of sulfonate 6 mg/L ~ 18mg/L, copper inhibitor 0.4 mg/L ~ 10mg/L.
Being mainly characterized by of this method adds a certain amount of sulphuric acid in recirculating cooling water system and controls the pH value of water at particular range, to improve cycles of concentration, thus reduces and supplements water consumption, saving water resource；Reduce water amount of blowdown, thus reduce the pollution to environment and the treating capacity of waste water；Save the consumption of water treatment agent simultaneously, thus reduce the cost of cold water process；Recirculated cooling water can run under the conditions of high concentration multiple, and water quality calcium firmly adds basicity and reaches 1400 ~ 1600
mg/L.Secondly, the present invention adds specific composite scale-inhibiting corrosion inhibitor, to reach to control recirculated cooling water to be still avoided that corrosion and scaling effect in the case of high calcium adds basicity firmly.
Described Part I anti-incrustation corrosion inhibitor is 24:10.5 with total mass ratio of adding of Part II anti-incrustation corrosion inhibitor.Part I anti-incrustation corrosion inhibitor and the adding proportion of Part II anti-incrustation corrosion inhibitor are relatively big to the scale inhibitor influential effect of recirculated water, can obtain best scale inhibitor effect when total interpolation mass ratio is in this ratio.
Preferably, described organophosphor is hydroxy ethylene diphosphonic acid or sodium ethylenediamine tetramethylenephosphonate.
Preferably, described phosphine carboxylic acid is 2-phosphonate group-1,2,4-butane tricarboxylates.
Preferably, described is 2-phosphonate group carboxyl sulfonate containing carboxyl and sulfonic copolymer.
The inventors found that when organophosphor selects hydroxy ethylene diphosphonic acid or sodium ethylenediamine tetramethylenephosphonate, phosphine carboxylic acid selection 2-phosphonate group-1,2,4-butane tricarboxylate, when selecting 2-phosphonate group carboxyl sulfonate containing carboxyl and sulfonic copolymer, self component facilitation of Part I anti-incrustation corrosion inhibitor can reach more preferably effect, at pH value in the case of 7.6 ~ 9.1, can under higher calcium adds basicity firmly non-scaling, metal protection is less.
Preferably, described zinc salt is zinc chloride or zinc sulfate.
Preferably, described co-polymer of sulfonate is acrylic acid-2-methacryl amido sulphonic acid copolymer.
When zinc salt selects zinc chloride or zinc sulfate, co-polymer of sulfonate selection acrylic acid-2-methacryl amido sulphonic acid copolymer.Self component facilitation of Part II anti-incrustation corrosion inhibitor can reach more preferably effect, at pH value in the case of 7.6 ~ 9.1, can keep recirculated water non-scaling under higher calcium adds basicity firmly.
The present invention selects sulphuric acid regulation when regulating pH, because sulfate radical corrosivity in water is less.Although traditional anti-incrustation corrosion inhibitor has scale inhibitor ability equally, but reaches 1200 ~ 1300 when recirculated cooling water high calcium adds basicity firmly
After mg/L, easily there is scale problems；Even if using and adding sulfuric acid treatment scheme, calcium adds basicity firmly to be also difficult to reach 1400
Mg/L and non-scaling.The two-part anti-incrustation corrosion inhibitor of subpackage that the present invention selects specific component to make.The anti-incrustation corrosion inhibitor of subpackage reacts to each other when respective system promotion, after joining in recirculated cooling water, can realize the scale inhibitor ability of maximum.
Compared with prior art, open type had the beneficial effect that the inventive method of recirculated cooling water method for treating water of the present invention adds sulphuric acid and controls the pH value of water to improve cycles of concentration, circulating cooling water quality calcium can be added basicity firmly and reach 1400 ~ 1600 mg/L, decrease fresh water rate of water make-up, slow down fouling and the corrosion of recirculated cooling water, improve cooling water control index and cycles of concentration, reduce fresh water water consumption rate.The present invention is matched by two parts anti-incrustation corrosion inhibitor of subpackage, the Hardness Control upper limit of recirculated cooling water can be greatly improved, thus reach higher calcium and firmly add under basicity still non-scaling improving cycles of concentration, keep minimum corrosivity, it is that the open type recirculated cooling water of high concentration multiple normally uses and is achieved, has a extensive future.
