Tlhaloso

Ts'ebeliso ea "evaporative crystallization skid" kalafong ea metsi a litšila ea setsi sa tlhoekiso ea khase ea tlhaho e hloka ho hlahlobisisoa hammoho le setšoantšo sa mohato oa Na2SO4-NaCl-H2O. Evaporative crystallization ha se feela mokhoa oa ho arola letsoai le metsi, empa hape o ka kopanya litšobotsi tsa ho qhibiliha ha letsoai le leng le le leng la inorganic ho arola letsoai le inorganic ka katleho ka mohato tsamaisong ea evaporative crystallization. E tšehetsoa ke tekano ea mohato, theknoloji e ka sebelisoa eseng feela ho hloekisa metsi a litšila tsa limela tsa tlhoekiso, empa hape le ka metsi a tšimo ea khase, brine e ka tlas'a lefatše, metsi a letša la letsoai le metsi a litšila a nang le letsoai le sa tšoaneng. Sebakeng sa karohano ea metsi a letsoai, karohano ea letsoai e ka finyelloa ka ho eketsehileng. Matsoai a arohaneng a ka sebelisoa hape ho latela boleng ba karohano, kapa a sebelisoa e le lisebelisoa tse tala tsa lik'hemik'hale, Kapa joalo ka letsoai la leruo la liphoofolo, le ke keng la hlokomela feela ho tsoa ha metsi a litšila, empa hape le ho hlokomela ho tsosolosoa ho utloahalang ha lisebelisoa tse fapaneng tsa bohlokoa.

Metsi a litšila a tsoang setsing sa tlhoekiso a qala ho kena karolong ea phekolo ea membrane ea RO. Kamora 'mekhahlelo e' meli ea membrane, metsi a hloekileng a sebelisoa hape. Metsi a koaletsoeng a kena ka letamong la concentrated 'me a kena tsamaisong ea evaporative crystallization ka pompo ea phepelo. Mocheng oa mouoane oa crystallization system, ka lebaka la ho qhibiliha ho fapaneng ha Na2SO4 le NaCI, ka moea oa metsi, mokelikeli oa lintho tse bonahalang o ntse o tsepame, 'me Na2SO4 e khethoa ka mokhoa o khethehileng le ho theoleloa ho etsa nitrate slurry. Nitrate slurry e kena tsamaisong ea centrifugal dehydration ka pompo ea slurry. Ka mor'a karohano ea metsi a tiileng, 'mè oa joala oa centrifugal o khutlela tsamaisong ea evaporative crystallization,' me letsoai le tiileng le rekisoa e le letsoai la indasteri. Ka moea oa mouoane, COD metsing a tala e matlafatsoa ke ho fokotseha ha metsi, e leng se lebisang ho eketseha ha viscosity ea mokelikeli oa phepelo ka tanka ea mouoane 'me e ama ka botebo ho hloekisoa ha letsoai ts'ebetsong ea mouoane.

Thepa ea phepelo ea skid ea evaporative crystallization skid e tsoa ho sesebelisoa sa electrodialysis se holimo, 'me matla a ho sebetsa a skid ke 300m3/d. Nako ea tlhahiso ea selemo ke lihora tse 8000.
Lisebelisoa tse ka sehloohong: Skid ea ho kopanya ts'ebetso, skid ea compressor, skid e tsoakiloeng ea hydrocarbon, sesebelisoa le sesebelisoa sa taolo.
