In the present embodiment, using in recirculated water be added carbon dioxide effectively control pH value, not only control pH value for a long time
It makes in the reasonable scope, and other water quality indicators can control and maintain good level.
In the debugging stage, due to equipment manufacturing defect early period, erection stage anti-corrosion is impaired or rinse stage is due to newly-built
Originally demineralized water water is limited for unit, leads to rinse unqualified, generation pH value raising, to prevent apparatus body from further corroding,
It generallys use addition ammonium hydroxide to be adjusted pH, ammonium hydroxide is carried out in two steps with reacting for the carbon dioxide in demineralized water:
NH3H2O+CO2=NH4HCO3
NH4HCO3+NH4OH=(NH4)2CO3+H2O
By above-mentioned reactional equation it is found that the carbon dioxide reaction in ammonium hydroxide and demineralized water is weak acid and weak base reaction, reaction
Final result is alkalescent, less free H+And OH-Reach chemical balance, the pH value of ammonification processing control loop water is certain
In range, tubing corrosion can be slowed down, but ammonia residual control aspect has certain difficulty, conductivity can also rise, therefore ammonification side
Formula effect is less desirable, is not recommended to use.
Since system debug operation plus carbon dioxide, pass through the prolonged water quality under different phase difference operating condition
Assay examination, circulating water quality is good, and the indexs such as pH value, iron and aluminium are always maintained in the reasonable scope, and system material is rotten
Erosion influences to be substantially reduced, and the service life of cool equipment between extension guarantees the long-term safety reliability service of unit.
Start water circulating pump 3 and carry out circulation flushing, detection recirculated water includes pH value, conductivity, iron content, aluminium content and hangs
Floating object should drain, and replaced with demineralized water when the conductivity of recirculated water is more than 50 μ S/cm.When conductivity is less than 10 μ S/cm, pH
Value is at 6.5~8.2, and after rinsing qualification, then successively demineralized water is rinsed on cooling triangle, and water rinses on each cooling triangle
3~4h continuously detects circulating water quality, mainly includes pH value, conductivity and aluminium content, keeps a close eye on pH in Circulating Water and aluminium contains
The situation of change of amount, it is ensured that water quality reaching standard.After bringing into operation when the pH value of recirculated water be more than or equal to 8.5, then into recirculated water plus
Enter carbon dioxide gas, so that the pH value of adjustment recirculated water is adjusted to 7.2-8.3.
It should be noted that the present invention is using carbon dioxide as gas media, and it is cheap to facilitate buying, it is easy to precisely control
It makes and adds, cooling system water correction is more soft between the weak acid environment pair formed after dissolution, more conducively controls, and to recirculated water
The influence of conductance is very limited, while not introducing other ions, effectively inhibits the chemical attack reaction of influence system material, in conjunction with
Automatic medicament feeding system accurately controls the additive amount of (pressure of decompression adjustment gas, flow) carbon dioxide, and recirculated water is effectively reduced
Middle erosive carbon dioxide makes pH value control in the reasonable scope to system corrosion of metal, guarantees cycle water safety.
