Ikhwalithi Ephakeme Abahlinzeki Bezimboni Zokuhlanza Igesi Yemvelo YaseChina - I-Evaporation skid crystallization - Rongteng

Incazelo

Ukusetshenziswa kwe-evaporative crystallization skid ekuhlanzeni amanzi angcolile embonini yokuhlanza igesi yemvelo kudingeka kuhlaziywe kuhlanganiswe nomdwebo wesigaba se-Na2SO4-NaCl-H2O. I-Evaporative crystallization ayiyona nje inqubo yokuhlukanisa usawoti namanzi kuphela, kodwa futhi ingahlanganisa izici zokuncibilika kosawoti ngamunye wezinto eziphilayo ukuze ihlukanise usawoti wezinto ezingaphili ngempumelelo ngesinyathelo ohlelweni lwecrystallization evaporative. Isekelwa ukulingana kwesigaba, ubuchwepheshe bungasetshenziswa hhayi kuphela ekulapheni kwamanzi angcolile ezitshalweni zokuhlanza, kodwa futhi emanzini asensimini yegesi, i-brine engaphansi komhlaba, amanzi echibi likasawoti kanye namanzi angcolile aqukethe usawoti ohlukahlukene we-inorganic. Ngokwesisekelo sokuhlukaniswa kwamanzi kasawoti, ukuhlukaniswa kukasawoti kasawoti kungafezwa ngokuqhubekayo. Usawoti ohlukanisiwe wezinto ezingaphili zingasetshenziswa kabusha ngokuya ngekhwalithi yokuhlukaniswa, noma zisetshenziswe njengezinto zokusetshenziswa zamakhemikhali, Noma njengosawoti wokufuywa kwezilwane, ongakwazi nje ukubona ukukhishwa okungenalutho kwamanzi angcolile, kodwa futhi abone ukugaywa kabusha okunengqondo kwezinhlobonhlobo zezinsiza ezibalulekile.

Amanzi angcolile asuka esitshalweni sokuhlanza angena kuqala eyunithi yokwelapha ulwelwesi lwe-RO. Ngemuva kokugxilisa ulwelwesi lwezigaba ezimbili, amanzi ahlanzekile aphinde asetshenziswe. Amanzi agxilile angena echibini eligxilile futhi angena ohlelweni lwecrystallization ehwamukayo ngephampu yokuphakelayo. Ohlelweni lwe-crystallization evaporative, ngenxa yokuncibilika okuhlukile kwe-Na2SO4 ne-NaCI, ngokuhwamuka kwamanzi, uketshezi olubonakalayo luyagxiliswa ngokwengeziwe, futhi i-Na2SO4 ikhethwa ngokukhethayo icwebezeliswe bese inemvula ukuze yakhe i-nitrate slurry. I-nitrate slurry ingena ohlelweni lwe-centrifugal dehydration ngokusebenzisa iphampu ye-slurry. Ngemuva kokuhlukana koketshezi oluqinile, utshwala obuyi-centrifugal bubuyela ohlelweni lwe-crystallization evaporative, futhi usawoti oqinile uthengiswa njengosawoti wezimboni. Ngokuhwamuka, i-COD emanzini aluhlaza inothiswa ngokuncipha kokuqukethwe kwamanzi, okuholela ekwandeni kwe-viscosity yoketshezi lokuphakelayo ethangini lomhwamuko futhi kuthinte kabi ukucwebezela kukasawoti enqubweni yokuhwamuka.

Impahla yokuphakelayo ye-evaporative crystallization skid ine-brine evela kudivayisi ye-electrodialysis ephezulu, futhi amandla okucubungula we-skid ngu-300m3/d. Isikhathi sokukhiqiza sonyaka singamahora angama-8000.
Imishini eyinhloko: Inqubo yokuhlanganisa i-skid, i-compressor skid, i-skid yokugcina i-hydrocarbon ehlanganisiwe, ithuluzi kanye nedivayisi yokulawula.
