Vim li cas thiaj yuav tsum siab -Zoo Stainless Hlau Plhaub- thiab -Tube Thaum tshav kub kub Exchangers siv nyob rau hauv Seawater Desalination?
Vim li cas thiaj yuav tsum siab -Zoo Stainless Hlau Plhaub- thiab -Tube Thaum tshav kub kub Exchangers siv nyob rau hauv Seawater Desalination?
Cov yam ntxwv ntawm Seawater:
Cov ntsiab lus siab chloride ion (kwv yees li 19,000 ppm)
Yooj yim rau pitting corrosion, crevice corrosion, thiab stress corrosion cracking (SCC)
Corrosiveness nce nrog kub dua
Standard 304 thiab 316L qib yuav tsim qhov thiab tawm hauv ob peb lub hlis nyob rau hauv siab - dej hiav txwv kub, yog li cov hauv qab no yuav tsum tau siv:
Common Material Qib (Sau los ntawm siab tshaj mus rau qis tshaj corrosion kuj)
Super Austenitic Stainless hlau
254 SMO, 654 SMO, AL-6XN, 2507 S32507
Muaj kwv yees li 6% Mo; resistant rau kub kub, siab chloride, thiab muaj zog acids
Siv nyob rau hauv MSF/MED siab-kub theem thiab core evaporators
Duplex Stainless hlau
2205 (feem ntau siv)
2507 (rau qhov chaw corrosive hnyav dua)
Lub zog siab, muaj zog corrosion kuj, thiab tus nqi - zoo
Feem ntau siv hauv condensers, qis-kub theem, thiab preheaters
Titanium Tubes (Ti)
Siab corrosion kuj, tab sis kim heev; siv tag nrho hauv titanium nkaus xwb rau cov haujlwm loj -.
Hom qauv ntawm Plhaub-thiab-Tube Thaum tshav kub kub Exchangers hauv Desalination
Hom: Tsau- raj- ntawv / Floating- taub hau plhaub- thiab - raj kub exchanger
Tube sab: Seawater / Brine / Chav
Plhaub sab: Cua sov chav / cua txias seawater
Tsim kub: 40-120℃(MED / MSF)
Cov ntsiab lus tseem ceeb:
Seawater corrosion kuj
Fouling kuj
Siab thiab nqus tsev vacuum
Leak- ua haujlwm pub dawb thaum lub sij hawm ntev - ua haujlwm tas mus li
