Inkcazo
Ukusetyenziswa kwe-evaporative crystallization skid kunyango lwamanzi amdaka kwisityalo sokucocwa kwegesi yendalo kufuneka kuhlalutywe kunye nomzobo wesigaba se-Na2SO4-NaCl-H2O. I-evaporative crystallization ayisiyonkqubo yokwahlula ityuwa namanzi kuphela, kodwa inokudibanisa iimpawu zokunyibilika kwetyuwa nganye engaphiliyo ukuze yahlule ityuwa engaphiliyo ngempumelelo ngenyathelo kwinkqubo ye-evaporative crystallization. Ixhaswa yi-phase equilibrium, le teknoloji ingasetyenziswa kungekuphela nje kunyango lwamanzi amdaka kwizityalo zokucocwa, kodwa nakwimanzi egesi, emanzini angaphantsi komhlaba, emanzini echibi letyuwa kunye namanzi amdaka aqulethe iityuwa ezahlukeneyo ezingaphiliyo. Ngokwesiseko sokwahlulwa kwamanzi etyuwa, ukwahlulwa kwetyuwa yetyuwa kunokufezekiswa ngakumbi. Iityuwa ezingaphiliyo ezahlulweyo zinokusetyenziswa kwakhona ngokomgangatho wokwahlulwa, okanye zisetyenziswe njengezinto ezikrwada zeekhemikhali, Okanye njengetyuwa yofuyo lwezilwanyana, engenakukwazi kuphela ukukhupha amanzi amdaka angapheliyo, kodwa ikwazi nokubuyisela kwakhona izixhobo ezahlukeneyo ezixabisekileyo.
Amanzi amdaka avela kwisityalo sokucoca angena kuqala kwiyunithi yonyango lwe-RO membrane. Emva koxinzelelo lwe-membrane olunezigaba ezibini, amanzi amatsha aphinda asetyenziswe. Amanzi axineneyo angena echibini elixineneyo aze angene kwinkqubo ye-crystallization evaporative ngepompo yokutya. Kwinkqubo ye-crystallization evaporative, ngenxa yokunyibilika okwahlukileyo kwe-Na2SO4 kunye ne-NaCI, ngokuphuma kwamanzi, ulwelo lwezinto luxutywe ngakumbi, kwaye i-Na2SO4 ikhethwa ukuba yi-crystallized kwaye ivuthwe ukuze yenze i-nitrate slurry. I-nitrate slurry ingena kwinkqubo yokuphelelwa ngamanzi kwe-centrifugal ngepompo ye-slurry. Emva kokwahlulwa kolwelo oluqinileyo, utywala be-centrifugal mama bubuyela kwinkqubo ye-crystallization evaporative, kwaye ityuwa eqinileyo ithengiswa njengetyuwa yemizi-mveliso. Ngokuphuma kwamanzi, i-COD emanzini aluhlaza ityetyiswa ngokuncipha komxholo wamanzi, okukhokelela ekwandeni kwe-viscosity yolwelo lokutya kwi-tank ye-evaporative kwaye kuchaphazela kakhulu i-crystallization yetyuwa kwinkqubo ye-evaporative.
Izinto zokutya ze-evaporative crystallization skid zimanzi amdaka avela kwisixhobo se-electrodialysis esinyukayo, kwaye amandla okucubungula e-skid yi-300m3/ngosuku. Ixesha lokuvelisa ngonyaka yi-8000 iiyure.
Izixhobo eziphambili: Iskidi yokudibanisa iinkqubo, iskidi yecompressor, iskidi yokugcina iihydrocarbon ezixutyiweyo, isixhobo kunye nesixhobo sokulawula.
