Tswelopele ya theknoloji ya tlhahiso ya haeterojene le tlhahlobo ya moruo – Tlhahiso ya haeterojene ka hara sele ya alkaline electrolytic

Tlhahiso ea haedrojene ea sele ea alkaline ke theknoloji ea tlhahiso ea haedrojene ea electrolytic e seng e holile haholo. Sele ea alkaline e bolokehile ebile e ka tšeptjoa, e phela lilemo tse 15, 'me e sebelisitsoe haholo khoebong. Bokhoni ba ho sebetsa ba sele ea alkaline ka kakaretso ke 42% ~ 78%. Lilemong tse 'maloa tse fetileng, lisele tsa alkaline electrolytic li hatetse pele ka likarolo tse peli tse kholo. Ka lehlakoreng le leng, bokhoni bo ntlafetseng ba sele bo ntlafalitsoe 'me litšenyehelo tsa ts'ebetso tse amanang le tšebeliso ea motlakase li fokotsehile. Ka lehlakoreng le leng, bongata ba hona joale ba ts'ebetso boa eketseha 'me litšenyehelo tsa matsete lia fokotseha.

Molao-motheo oa ts'ebetso oa alkaline electrolyzer o bontšitsoe setšoantšong. Betri e na le li-electrode tse peli tse arotsoeng ke diaphragm e sa keneng moea. Kopano ea betri e qoelisoa ka har'a khatello e phahameng ea alkaline liquid electrolyte KOH (20% ho isa ho 30%) ho eketsa conductivity ea ionic. Litharollo tsa NaOH le NaCl le tsona li ka sebelisoa e le li-electrolyte, empa ha li sebelisoe hangata. Bothata bo boholo ba li-electrolyte ke hore lia senya. Sele e sebetsa mochesong oa 65 °C ho isa ho 100°C. Cathode ea sele e hlahisa haedrojene, 'me OH e hlahisoang - e phalla ka diaphragm ho ea anode, moo e kopanang hape ho hlahisa oksijene.

Lisele tse tsoetseng pele tsa alkaline electrolytic li loketse tlhahiso e kholo ea haedrojene. Lisele tsa alkaline electrolytic tse entsoeng ke bahlahisi ba bang li na le bokhoni bo phahameng haholo ba tlhahiso ea haedrojene ho (500 ~ 760Nm3/h), ka tšebeliso e tsamaellanang ea matla a 2150 ~ 3534kW. Ha e le hantle, ho thibela ho thehoa ha metsoako ea khase e tukang, chai ea haedrojene e lekanyelitsoe ho 25% ho isa ho 100% ea sebaka se lekantsoeng, bongata bo boholo ba hona joale bo lumelletsoeng ke hoo e ka bang 0.4A/cm2, mocheso oa ts'ebetso ke 5 ho isa ho 100°C, 'me khatello e phahameng ka ho fetisisa ea electrolytic e haufi le 2.5 ho isa ho 3.0 MPa. Ha khatello ea electrolytic e phahame haholo, litšenyehelo tsa matsete lia eketseha 'me kotsi ea ho thehoa ha motsoako o kotsi oa khase e eketseha haholo. Ntle le sesebelisoa leha e le sefe se thusang sa tlhoekiso, bohloeki ba haedrojene bo hlahisoang ke electrolysis ea sele ea alkaline bo ka fihla ho 99%. Metsi a electrolytic a sele ea alkaline electrolytic a tlameha ho ba a hloekileng, e le ho sireletsa electrode le ts'ebetso e sireletsehileng, ho tsamaisa metsi ho ka tlase ho 5S/cm.
