Panthawi yopanga mabizinesi a petrochemical,
Kuchuluka kwa madzi otayika ndi kwakukulu ndipo kapangidwe kake ndi kovuta.
Njira yophatikizira ndizovuta kuthana nayo!
Makamaka mowa wambiri wamchere komanso wa COD wambiri pamapeto pake,
Ngati sichingawumitsidwe bwino,
Zikhudza kwambiri kukwaniritsidwa kwa "zero discharge" yamadzi oyipa!
Njira yodziwika ya kuyanika kwa mowa wamayi kumapeto kwa njira yopangira madzi a petrochemical
Popanga mabizinesi a petrochemical, njira ya evaporation / kuzizira kwa crystallization ndi njira yomwe imagwiritsidwa ntchito kwambiri kuti mupeze chomaliza.Njira ya crystallization idzatsogolera ku kulemeretsa zonyansa muzinthuzo, kotero kuti mowa wochuluka kapena wocheperako womwe umasungunuka umapangidwa popanga.
Pakalipano, chithandizo cha zakumwa zoledzeretsa za amayi zomwe zasungunuka zimathetsedwa ngati vuto linalake popanga.Chifukwa cha zinthu zosiyanasiyana za mowa wa mayi wokha, njira zochiritsira zimakhalanso zosiyana.Pakutaya chakumwa cha mayi chomwe chasanduka nthunzi chokhala ndi mchere wambiri komanso COD wochuluka, matekinoloje ochiritsira omwe amapezeka pamsika makamaka amawumitsa ng'oma, kuyanika kwamadzi, ketulo imodzi ya nthunzi komanso njira yochepetsera kutentha kwa crystallization.Makhalidwe a njira zinayi zazikuluzikulu zogwirira ntchito, kugwiritsa ntchito nthunzi, kugwiritsa ntchito mphamvu, mawonekedwe ogwiritsira ntchito, mawonekedwe a zida ndi kuchuluka kwa ntchito akufaniziridwa motere:
| Zida zamtundu | mphamvu | kumwa nthunzi | Kugwiritsa ntchito mphamvu | Magawo ogwiritsira ntchito | Zida Zida | Kusiyanasiyana kwa ntchito |
| Kuyanika kwa roller scraper | 5000L/d | 1.5t/tani madzi | 22W | Kuyanika kwa vacuum, kuyanika mumlengalenga Pamwamba pa 60 ℃ | Kapangidwe kosavuta, ntchito yosavuta, mfundo yosavuta | Chakumwa choledzeretsa chachikulu cha amayi, chokwera kwambiri cha C00 |
| Kusindikiza kwa zida sikuli bwino, fungo la pamalopo ndi lalikulu, ndipo chitetezo cha ogwira ntchito ndi choyipa. | ||||||
| Ikhoza kutenthedwa ndi mafuta otumizira kutentha, nthunzi, etc. | ||||||
| Chitsulo chosapanga dzimbiri, duplex zitsulo | ||||||
| Chandamale kuyanika | 5000L/d | 1.5t/tani madzi | 22W | Kuyanika kwa vacuum, kuyanika mumlengalenga Pamwamba pa 60 ℃ | Mapangidwe ake ndi osavuta, ntchitoyo ndi yosavuta, malo apansi ndi aakulu, chiwerengero cha ndende cha zipangizo ndi chochepa kwambiri, ndipo kutentha kwa ntchito kumakhala kwakukulu. | Chakumwa choledzeretsa chachikulu cha amayi, chokwera kwambiri cha C00 |
| Ikhoza kutenthedwa ndi mafuta otumizira kutentha, nthunzi, madzi otentha, ndi zina zotero. | ||||||
| Chitsulo chosapanga dzimbiri, duplex zitsulo | ||||||
| Single Pa | 5000L/d | 1.2t/tani madzi | 25W | Vacuum distillation, atmospheric distillation Pamwamba pa 60 ℃ | Imafunika kupanga nsanja, koma mfundo ya zida ndi yosavuta ndipo ntchitoyo ndi yosavuta.Pitani ku zinthu zowoneka bwino, kutulutsa kumakhala kwa hemp | Chakumwa choledzeretsa chachikulu cha amayi, chokwera kwambiri cha C00 |
| Ikhoza kutenthedwa ndi mafuta otumizira kutentha, nthunzi, etc. | ||||||
| Enamel zakuthupi | ||||||
| Low kutentha nthunzi crystallization | 5000L/d | 1.1t/tani madzi | 7.5W | otsika kutentha evaporator 30-400 | Kuphatikizika kwakukulu, digiri yapamwamba yodzipangira okha, kusindikiza kwabwino kwa zida, palibe fungo lachilendo pakugwira ntchito pamalopo, kutentha kwapang'onopang'ono, osafunikira ogwiritsira ntchito apadera pamalopo. | Mowa wambiri wamayi, zinthu zambiri za COD, zinthu zomwe zimakhudzidwa ndi kutentha |
| Chitsulo chosapanga dzimbiri, duplex chitsulo, titaniyamu, etc. |
△Kuwunika kofananira kwa zida zowumira wamba ndi njira yotsika yotentha ya nthunzi
Weishengda chilengedwe chitetezo otsika kutentha evaporation crystallizer makamaka ntchito kuchepetsa ndi ndende ya mkulu- ndende madzi zinyalala.Chokhachokha chokhazikika chimakhala chothandiza kwambiri pochiza madzi osungunuka omwe ndi osavuta kumamatira pakhoma.Zimalimbikitsidwa makamaka pochiza madzi osakanikirana kapena osakanikirana, monga heavy metal wastewater, high brine, mowa wa amayi, reverse osmosis anaikira madzi, etc. Dongosolo utenga Miller mbale jekete kwa kutentha kuwombola, ndi zingalowe digiri mu chipinda evaporation ndi -95~-97kPa, ndipo kutentha kwa evaporation kumasungidwa pakati pa 40 ~ 45°C.Chipinda cha evaporation chimagwiritsa ntchito spiral scraper kusonkhezera, chomwe chingatsimikizire kutentha kofanana.Panthawi imodzimodziyo, kuyika shaft yoyambitsa kutentha kungapangitse kusinthana kwa kutentha ndikuwongolera kuuma kwa zotsatira.
Dongosolo ndi kuwongolera kwathunthu, ndi mawonekedwe a kutulutsa basi, kuyeretsa basi, kasamalidwe ka nsanja yamtambo ndi zina zotero.Mphamvu yotulutsa madzi ndi yabwino, palibe kuwononga mpweya wotayirira, kuwononga kutentha ndi zochitika zina, ndipo dongosolo lonse limagwira ntchito motsekedwa.
△ Chithunzi chojambula cha kristalo chotsika kutentha kwa evaporation
2 Kugwiritsa ntchito njira ya WSD yotsika kutentha kwa evaporation crystallization m'madzi onyansa a petrochemical
Makasitomala ndi bizinesi yamafuta ndi gasi yomwe imapanga gasi wachilengedwe.Kuchuluka kwa madzi otayira opanda mphamvu, madzi obwezeredwa wamba, madzi otayira ozungulira ndi zotayira mu boiler amapangidwa.Pali vuto la madzi otayira amchere ambiri, omwe amakhudza kwambiri chipangizo chochotsera zimbudzi.Madzi otayira amchere wambiri amakhala ndi sodium sulfate komanso mtengo wapamwamba wa COD.Pambuyo pa WSD skid-wokwera mayi wowumitsa mowa (tsiku ndi tsiku madzi otayira 10m³), madzi opangidwa amakhala opanda mtundu ndipo alibe fungo lopweteka, ndipo pH mtengo ndi pakati pa 6 ndi 9. L, ndi COD ndi zosakwana 40mg / L, madzi opangidwa ndi oyenerera, omwe amakwaniritsa zofunikira zolowa mu dziwe la biochemical kuti athandizidwe komanso amakwaniritsa zofunikira za utsi.

△Yesani data ndi tebulo lamtundu wamadzi
△Zithunzi za madzi opangidwa ndi slag
Zero discharge treatment of petrochemical wastewater ndiye njira yamtsogolo yachitukuko.Kuchepetsa kwakukulu kwamadzi onyansa a petrochemical ndi ukadaulo wocheperako kutentha kumatha kuchepetsa kuchuluka kwa evaporation ndi crystallization, kuchepetsa mtengo wokwanira waumisiri wamankhwala osatulutsa ziro, ndikupereka zidziwitso ndi mafotokozedwe ogwiritsira ntchito ndi chitukuko chaukadaulo wa zero-discharge for makampani a petrochemical m'tsogolomu.
