A PVC lined FRP scrubberrau chlor-alkali kev lag luam nyuam qhuav ua tiav nws cov txheej txheem tseem ceeb ntawm peb lub Hoobkas (Hebei Jiarui FRP Co., Ltd.) thiab tam sim no tab tom ua haujlwm ntawm - qhov chaw sib dhos ntawm kev txhawb nqa skid. Cov cuab yeej tau teem caij xa los ntawm hiav txwv mus rau chlorine loj-alkali ntau lawm hauv Indonesia nyob rau nruab nrab-lub hlis tom ntej los kho cov tshuaj acidic thiab cov tshuaj chlorine nkag rau hauv cov txheej txheem tail gas.
Cov cuab yeej tsim khoom nkag mus rau theem kawg
Raws li lub Hoobkas, lub cev tseem ceeb ntawm lub tshuab ntxhua khaub ncaws no yog cov txheej txheem sib xyaw nrog fiberglass (FRP) raws li cov txheej txheem txheej txheem thiab polyvinyl chloride (PVC) ua cov txheej txheem sab hauv. Kev ua haujlwm tam sim no tsom mus rau kev sib dhos kev sib tw: cov kev txhawb nqa skid yog cov khoom sib txuas ntawm hauv qab ntawm cov khoom siv thiab lub hauv paus platform, thiab lawv cov vuam kev sib raug zoo ncaj qha cuam tshuam ncaj qha rau verticality thiab tiv thaiv -tipping peev xwm ntawm ntauwd lub cev thaum thauj thiab ua haujlwm. Pab pawg sib dhos tau kho lub thauj tog rau nkoj ntsia hlau txoj haujlwm ib los ntawm ib qho thiab siv cov kev tiv thaiv theem nrab - kev kho corrosion rau cov mating nto ntawm lub hauv paus thiab qis kawg cap ntawm tus pej thuam. Xav txog cov av noo thiab siab ntsev tsuag ib puag ncig ntawm Indonesian qhov project site, qhov kev tsim kho tshiab no yog qhov tsim nyog tshwj xeeb.
Corrosion Resistance Design rau Chlor-Alkali txheej txheem
Cov pa pa tawm los ntawm chlor-alkali kev lag luam yog qhov tsis zoo corrosive hauv kev lag luam tshuaj. Cov tshuaj chlorine, hydrogen chloride, thiab entrained hypochlorous acid droplets tso tawm thaum lub sij hawm electrolysis ntawm brine, yog hais tias ncaj qha tawm mus rau hauv cov kav dej tom ntej, tuaj yeem corrode cov khoom siv carbon steel zoo tib yam hauv lub hlis. Qhov PVC no -lined FRP scrubber hais txog qhov kev sib tw no nrog ob- txheej txheej tsim: PVC hauv ob sab phlu ncaj qha hu rau nruab nrab gaseous, siv nws cov tshuaj tiv thaiv zoo heev rau chloride ion nkag mus los thaiv cov tshuaj tua kab mob; FRP txheej txheej muab cov txheej txheem muaj zog thiab tsis kam rau sab nraud, thaum tseem ua haujlwm tiv thaiv kev tiv thaiv ntau dhau ntawm PVC vim qhov kub thiab txias. Nws yog tsim nyog sau cia tias ob cov ntaub ntawv no yog tsim los nrog sib npaug coefficients ntawm thermal expansion-qhov tsis muaj zog hauv ntau qhov kev ua tsis tiav yav dhau los.
Kev Ntsuam Xyuas luv luv ntawm Kev Xaiv Scrubber rau Chlor-Alkali Kev Ua Haujlwm
Nws yog ib qho tsim nyog los taw qhia tias tsis yog txhua tus PVC-lined FRP scrubbers yog tsim rau tuav siab -kub chlorine gas. Thaum qhov kub ntawm qhov hluav taws xob ntau tshaj 65 degree, qhov kev pheej hmoo ntawm softening ntawm PVC hauv ob sab phlu nce ntau heev. Cov khoom xa tawm nyob rau hauv rooj plaub no yog tsim nyog vim tias cov txheej txheem tsis tau muab los ntawm Indonesian qhov project tog nruj me ntsis tswj tus Tsov tus tw gas inlet kub hauv qab 52℃(lub quench pej thuam tau ntsia rau pem hauv ntej kawg). Yog tias qhov kub siab dua, PP (polypropylene) hauv ob sab phlu lossis tag nrho -FRP qauv yuav tsum tau siv-tab sis ob qhov tom kawg tsis tshua muaj chlorine oxidation dua li PVC. Qhov kev lag luam no-tawm hauv kev xaiv cov khoom muaj tseeb qhia txog cov tswv yim zoo hauv cov tshuaj tiv thaiv corrosion: "Tsis muaj qhov zoo tshaj plaws, tsuas yog qhov cuam tshuam ntau tshaj plaws."
Kev sib dhos ntawm cov cuab yeej yuav tsum ua kom tiav thaum kawg ntawm lub hlis no, ua raws li qhov kawg ntawm kev ntsuas huab cua (kuaj siab 0.12MPa, siab tuav rau 30 feeb). Daim ntawv sau npe nrog "PVC-lined FRP scrubber"-ua los ntawm 316L stainless hlau, tiv taus dej hiav txwv corrosion- tau raug kho thiab tos kev teeb tsa hauv qab lub nplhaib txhawb nqa hauv nruab nrab ntawm lub cev ntauwd.
