Thaum lub sij hawm tsim cov txheej txheem ntawm kev lag luam petrochemical,
Cov dej khib nyiab tawm ntim yog loj thiab muaj pes tsawg leeg yog complex.
Cov txheej txheem ua ke yog qhov nyuaj rau kev daws!
Tshwj xeeb tshaj yog cov ntsev thiab siab-COD niam cawv thaum kawg,
Yog tias nws tsis tuaj yeem qhuav kom zoo,
Nws yuav cuam tshuam rau kev ua tiav ntawm "zero paug" ntawm cov dej khib nyiab!
Cov txheej txheem ntawm niam cawv kom qhuav thaum kawg ntawm cov txheej txheem petrochemical wastewater kho
Nyob rau hauv cov txheej txheem ntawm cov tuam txhab petrochemical, cov txheej txheem evaporation / freezing crystallization yog cov txheej txheem uas nquag siv kom tau txais cov khoom kawg.Cov txheej txheem crystallization yuav ua rau muaj kev nplua nuj ntawm impurities hauv cov khoom, yog li ntau dua los yog tsawg dua evaporated niam cawv yuav raug tsim nyob rau hauv cov txheej txheem ntau lawm.
Tam sim no, kev kho mob ntawm cov evaporated niam cawv yog qhov pib daws raws li qhov teeb meem tshwj xeeb hauv cov txheej txheem tsim khoom.Vim muaj cov khoom sib txawv ntawm niam cawv nws tus kheej, txoj kev kho mob kuj txawv.Rau kev pov tseg ntawm evaporated niam cawv nrog siab ntsev thiab siab COD, cov thev naus laus zis kho mob hauv kev lag luam feem ntau yog nruas scraper ziab, rake drying, ib chav boiler thiab qis kub evaporation crystallization txheej txheem.Cov yam ntxwv ntawm plaub txheej txheem loj nyob rau hauv cov nqe lus ntawm kev muaj peev xwm, chav noj, lub zog noj, kev khiav hauj lwm parameter yam ntxwv, cov yam ntxwv ntawm cov cuab yeej thiab Scope ntawm daim ntawv thov yog muab piv raws li nram no:

△ Kev sib piv ntawm cov khoom siv ziab kom qhuav thiab cov txheej txheem kub tsis tshua muaj qhov cub crystallization
Weishengda ib puag ncig tiv thaiv qis-kub evaporation crystallizer tshwj xeeb yog siv rau kev txo qis thiab kev xav ntawm cov dej khib nyiab siab.Lub built-in scraper muaj txiaj ntsig zoo hauv kev kho cov kua qaub uas yooj yim lo rau ntawm phab ntsa.Nws yog tshwj xeeb tshaj yog pom zoo rau kev kho mob ntawm cohesive los yog crystallized kua, xws li hnyav hlau khib nyiab, siab brine, leej niam cawv, rov qab osmosis concentrated dej, thiab lwm yam. Lub system txais Miller phaj tsho rau tshav kub exchanger, lub nqus tsev kawm ntawv nyob rau hauv lub evaporation chamber yog. -95 ~ -97kPa, thiab evaporation kub feem ntau khaws cia ntawm 40 ~ 45 ° C.Lub evaporation chamber siv lub kauv scraper rau do, uas tuaj yeem ua kom muaj cua sov zoo ib yam.Nyob rau tib lub sijhawm, kev teeb tsa lub ntsej muag nplawm kom sov tuaj yeem txhim kho cov txiaj ntsig kev sib hloov cua sov thiab txhim kho qhov ziab ntawm cov zis.
Lub kaw lus yog tag nrho tsis siv neeg tswj, nrog cov yam ntxwv ntawm tsis siv neeg paug, tsis siv neeg tu, khoom siv huab platform tswj thiab lwm yam.Cov dej tawm qhov hluav taws xob yog qhov zoo, tsis muaj cov pa paug paug, cua sov thiab lwm yam tshwm sim, thiab tag nrho cov txheej txheem ua haujlwm kaw.
△ Daim duab qhia kev ua haujlwm ntawm qhov kub thiab txias evaporation crystallizer
2 Daim ntawv thov ntawm WSD qhov kub thiab txias evaporation crystallization txheej txheem hauv petrochemical cov dej khib nyiab
Cov neeg siv khoom yog cov lag luam roj thiab roj ua lag luam feem ntau tsim cov pa roj.Ib tug loj npaum li cas ntawm neutralized wastewater, txheem reclaimed dej, circulating dej effluent thiab boiler effluent yog tsim.Muaj teeb meem ntawm cov dej khib nyiab siab, uas muaj kev cuam tshuam zoo rau cov khoom siv dej phwj tuaj.Cov dej khib nyiab siab muaj sodium sulfate thiab cov nqi COD siab.Tom qab WSD skid-mounted niam cawv kom qhuav qhov system (txhua txhua hnub kev kho dej khib nyiab 10m³), cov dej uas tsim tawm tsis muaj xim thiab tsis muaj ntxhiab tsw, thiab pH tus nqi yog nyob nruab nrab ntawm 6 thiab 9. Yog tias qhov concentration ntawm sulfite + sulfate tsawg dua 10mg / L, thiab COD tsawg dua 40mg / L, cov dej tsim tau tsim nyog, uas ua tau raws li qhov yuav tsum tau nkag mus rau hauv biochemical pas dej ua ke rau kev kho mob thiab kuj ua tau raws li qhov yuav tsum tau ua rau cov dej ntws tawm.
△ Daim ntawv qhia chaw nyob
△Kuaj cov ntaub ntawv thiab cov lus dej zoo
△ Cov duab ntawm cov dej thiab cov slag tawm
Zero tawm kev kho cov dej khib nyiab petrochemical yog kev txhim kho yav tom ntej.Kev txo qis ntawm petrochemical cov dej khib nyiab los ntawm qhov kub thiab txias evaporation thev naus laus zis tuaj yeem txo qhov kev ua haujlwm ntawm evaporation thiab crystallization, txo tus nqi ntawm xoom-tso tawm kev kho engineering, thiab muab kev siv thiab siv rau daim ntawv thov thiab kev loj hlob ntawm xoom-tso tshuab rau petrochemical kev lag luam yav tom ntej.
