Lub tshuab hluav taws xob chav yog lub plawv ntawm tsob nroj uas tso siab rau cov txheej txheem chav. Nws txoj kev ntseeg tau thiab lub neej yog cov neeg muaj sia nyob yuav luag txhua yam: qhov zoo ntawm pub dej- cov khoom uas lub nkoj tau ua. Cov dej tsis zoo yuav teev, corrode thiab thaum kawg ua kom puas txawm tias qhov kev xaiv tsis ncaj ncees lawm
Kab lus no piav qhia kev sib txuas ntawm cov khoom siv chemistry, thiab hnub - hnub ua ke yog li koj lub tshuab ua haujlwm ntev li ntev- yog li ua tau.
1. Dej Zoo: Tus Killer Silent
1.1 Yuav ua li cas tsis ncaj ncees lawm thaum dej lawm tsis kho
• Nplai: 1 hli ntawm calcium - Magnesium carbonate roj carbonate ntau ntxiv los ntawm 10%; 3 HLM txiav cov dej num ua haujlwm los ntawm 25%.
• Corrosion: Pub - dej nrog pH <8 lossis siab}} Muaj kev pheej hmoo ntawm kev pheej hmoo ntawm kev puas tsuaj tawg.
• Creeping Lauj: Cov kauj vab ua raws li insulator, yuam tus neeg tawg hlav khiav ntev dua thiab kub dua, ua kom nrawm dua qub.
1.2 Cov dej tshwj xeeb uas muaj teeb meem
• Alkalinity thiab Ph
- Tag nrho Alkalinity: 8.0-26.0 mmol / l
- phenolphthtain alkalinity: 6.0-18.0 mmol / l
- P @ 25 degree: 10.0-12.0 (khaws cov hlau passive thiab minimizes cov khoom xeb corrosion)
• Kev coj ua & cov khib nyiab yaj
- Conductivity tsawg dua los yog sib npaug rau 8 000 μs / cm 90 degree
- Tag nrho cov khib nyiab yaj tsis muaj tsawg dua lossis sib npaug rau 5 000 mg / l
• Cov tshuaj lom neeg
- PUAS: 10-50 MG / L (ua cov yeeb yaj kiab los tiv thaiv kab mob phosphate)
- No₂⁻: 10-30 mg / l (ua raws li anodic corrosion inhibitor)
2. Cov Khoom Xaiv: Carbon Steel vs. Stainless Hlau
Cov Hlau Steel Steel Steel Steel Steel Stainless Hlau
Up -} pem hauv ntej nqi qis 50-100% siab dua
Corrosion tus nqi siab yog tias dej acidic<0.002 mm/year (typ.)
Dej tiv thaiv hardness tsawg dua los yog sib npaug rau 0.03 mmol / l hardness tsawg dua los yog sib npaug rau 1.0 hli / l
Chloride Txwv<30 mg/L <50 mg/L (to avoid pitting)
Txij Nkawm Lub Hli Phab Ntsa {{}} thickness tsom rau Weld Soj ntsuam
Txoj cai ntawm tus ntiv tes xoo
Yog tias koj tuaj yeem lav ultra - Dej muag (ro permeate lossis zoo dua), pa roj carbon monoxial. Hauv tag nrho lwm qhov xwm txheej - Tshwj xeeb yog qhov twg cov taub dej nyoos yog saum lub neej qis dua (LCC) txawm hais tias tus nqi yuav siab dua.
3.Qaute: Ua dej thiab cov khoom ua haujlwm ua ke
3.1 Ua ntej - kev kho
Nruab ib qho rov qab - ovmosis (ro {{} Pauv Hloov Softener uas xa:
• Kev ua tau zoo <10 μs / cm
• HARDNESS ≈ 0 MMOL / L
Tsis txhob pub lub tshuab hluav taws xob ncaj qha nrog cov hauv nroog, zoo lossis cov dej saum npoo tsis yog txhua hnub tshuab {}} down yog nruj me ntsis siv.
3.2 tiag -} kev soj ntsuam
Haum rau hauv online conductivity meters ntawm ob inlet thiab qhov hluav taws xob kab; Teeb lub tswb ntawm 50 μs / CM thiab Interlock kaw lub qhov cub tawg. Hla - check txhua lim tiam nrog poob - Cov khoom siv ntsuas kom paub cov khoom siv.
3.Zoo tshuab -} down & tu
• Kev tuav tshuab tshuab -} down: txhua qhov ua haujlwm, ib lub chaw tsim khoom lag luam.
• Kev Tu Kom huv: Tinesy- pa qaub hle cov nplai uas tau pib ua.
3.4 cov khoom siv -}} kev kuaj pom
• Cov hlau carbon: Ultrasonic Thickness Tag Huv Tag Nrho Cov Ntawv; Hloov txoj hlab thaum corrosion ntau dua 0.2 mm / xyoo.
• Stainless hlau: zas - penetant lossis eddy {1} {} Kev xeem ntawm Welds txhua rau lub hlis; Saib rau chloride - inducts kev ntxhov siab- corrosion nrib pleb.
Tsim cov dej txhua hnub - Xyuas cov khoom siv rau cov dej koj tuaj yeem tsim tiag tiag, thiab xaiv cov neeg muag khoom tiag tiag, thiab xaiv cov neeg muag khoom lub neej, Shangrao) Ua li no thiab zoo {{{- Cov roj tsim hluav taws xob tuaj yeem khiav mus rau 20 lub zog roj, downtime thiab peev raws txoj kev.
