Umgangatho oPhezulu waseTshayina weYunithi yokuMphunga yeCrystallization aBavelisi-I-Evaporation crystallization skid – Rongteng

Inkcazo

Ukusetyenziswa kwe-evaporative crystallization skid kunyango lwamanzi amdaka kwiplanti yokucoca igesi yendalo kufuneka ihlalutywe ngokudityaniswa nomzobo wesigaba se-Na2SO4-NaCl-H2O. I-Evaporative crystallization ayiyonkqubo yokwahlula ityuwa kunye namanzi kuphela, kodwa inokudibanisa iimpawu zokunyibilika kwetyuwa nganye ye-inorganic ukwahlula ityuwa ye-inorganic ngempumelelo ngenyathelo kwinkqubo yecrystallization evaporative. Ixhaswa yi-equilibrium yesigaba, itekhnoloji ingasetyenziselwa kuphela kunyango lwamanzi amdaka kwizityalo zokucoca, kodwa nakwindawo yegesi yamanzi, i-brine engaphantsi komhlaba, amanzi echibi letyuwa kunye namanzi amdaka aqulethe iityuwa ezahlukeneyo. Kwisiseko sokuhlukana kwamanzi etyuwa, ukuhlukana kwetyuwa yetyuwa kunokufezekiswa ngakumbi. Iityuwa ezicaluliweyo zingaphinda zisetyenziswe ngokomgangatho wokwahlula, okanye zisetyenziswe njengemathiriyeli ekrwada yekhemikhali, Okanye njengetyuwa efuywayo yezilwanyana, engakwaziyo ukuqonda kuphela ukukhutshwa kwamanzi amdaka, kodwa kwakhona iqonde ukurisayikilishwa okusengqiqweni kwezinto ezahlukeneyo ezixabisekileyo.

Amanzi amdaka avela kwisityalo sokucoca kuqala angena kwiyunithi yonyango ye-membrane ye-RO. Emva kokugxilwa kwe-membrane yamanqanaba amabini, amanzi ahlambulukileyo aphinda asetyenziswe. Amanzi agxininisiweyo angena kwi-pool edibeneyo kwaye angena kwinkqubo ye-evaporative crystallization ngokusebenzisa impompo yokutya. Kwi-evaporative crystallization system, ngenxa ye-solubility eyahlukileyo ye-Na2SO4 kunye ne-NaCI, kunye nokunyuka kwamanzi, ulwelo lwezinto eziphathekayo lugxininiswe ngakumbi, kwaye i-Na2SO4 ikhethwa ngokukhethekileyo kwaye iyancipha ukwenza i-nitrate slurry. I-nitrate slurry ingena kwi-centrifugal dehydration system ngokusebenzisa impompo ye-slurry. Emva kokwahlulwa kolwelo oluqinileyo, i-centrifugal mother liquor ibuyela kwi-evaporative crystallization system, kwaye ityuwa eqinileyo ithengiswa njengetyuwa yeshishini. Ngomphunga, i-COD emanzini akrwada iyatyetyiswa ngokuhla komxholo wamanzi, nto leyo ekhokelela ekwandeni kwe-viscosity yolwelo lokutya kwitanki yokuphuma komphunga kwaye ichaphazela ngokunzulu icrystallization yetyuwa kwinkqubo yokuphuma komphunga.

Izinto zokutya ze-evaporative crystallization skid yibrine esuka kwisixhobo sokuhlaziya i-electrodialysis, kunye nomthamo wokusetyenzwa kweskid yi-300m3/d. Ixesha lemveliso yonyaka yiyure ye-8000.
Izixhobo eziphambili: Inkqubo yokudibanisa i-skid, i-compressor skid, i-skid yokugcina i-hydrocarbon edibeneyo, isixhobo kunye nesixhobo sokulawula.
