Sisebenzisa inkqubo yokukhupha i-flue gas desulfurization (FGD) yesikhululo samandla esisebenza ngamalahle njengomzekelo, olu hlalutyo luhlola imiba kwiinkqubo zamanzi amdaka zemveli ze-FGD, ezifana noyilo olubi kunye namazinga aphezulu okusilela kwezixhobo. Ngokusebenzisa ukulungiswa okuninzi kunye notshintsho lobuchwephesha, umxholo oqinileyo kumanzi amdaka uncitshisiwe, kuqinisekiswa ukusebenza kwenkqubo eqhelekileyo kunye nokunciphisa iindleko zokusebenza kunye nokugcinwa. Izisombululo ezisebenzayo kunye neengcebiso zacetyiswa, zibonelela ngesiseko esiqinileyo sokufezekisa ukukhutshwa kwamanzi amdaka kwixesha elizayo.
1. Isishwankathelo seNkqubo
Izikhululo zamandla ezisebenzisa amalahle zihlala zisebenzisa inkqubo ye-limestone-gypsum wet FGD, esebenzisa i-limestone (CaCO₃) njengento efunxa amanzi. Le nkqubo ngokungenakuphepheka ivelisa amanzi amdaka e-FGD. Kule meko, iinkqubo ezimbini ze-FGD ezimanzi zabelana ngeyunithi enye yokucoca amanzi amdaka. Umthombo wamanzi amdaka yi-gypsum cyclone overflow, ecutshungulwa kusetyenziswa iindlela zemveli (inkqubo yeetanki ezintathu) enomthamo oyilwe we-22.8 t/h. Amanzi amdaka acociweyo ampontshwa iikhilomitha ezi-6 ukuya kwindawo yokulahla ukuze kuncitshiswe uthuli.
2. Imiba Emikhulu Kwinkqubo Yokuqala
I-diaphragm yeempompo zokulinganisa yayidla ngokuvuza okanye ingaphumeleli, nto leyo eyayithintela ukuchama rhoqo kweekhemikhali. Amanqanaba aphezulu okusilela kwiiprinta zesihluzo zepleyiti kunye nefreyimu kunye neempompo zokulahla inkunkuma andise iimfuno zabasebenzi kwaye athintela ukususwa kwenkunkuma, nto leyo eyayinciphisa ukutyibilika kwenkunkuma kwizixhobo zokukhanyisa.
Amanzi amdaka, avela kwi-gypsum cyclone overflow, ayenobunzima obumalunga ne-1,040 kg/m³ kunye nomxholo oqinileyo we-3.7%. Oku kuphazamisa amandla enkqubo okukhupha amanzi acociweyo rhoqo nokulawula ubuninzi bee-ion eziyingozi kwi-absorber.
3. Utshintsho lokuqala
Ukuphucula iMilinganiselo yeeKhemikhali:
Kwafakelwa ezinye iitanki zeekhemikhali phezu kwenkqubo yeetanki ezintathu ukuqinisekisa ukuba idosi isetyenziswa rhoqo ngomxhuzulane, ilawulwa yi-animitha yoxinaniso kwi-intanethi.
Isiphumo: Umgangatho wamanzi ophucukileyo, nangona ukutsalwa kwenkunkuma kwakusafuneka. Ukukhutshwa kwamanzi imihla ngemihla kwehle kwaya kwi-200 m³, nto leyo eyayinganelanga ukusebenza ngokuzinzileyo kweenkqubo ezimbini ze-FGD. Iindleko zokulinganisa zaziphezulu, ziphakathi kwe-12 CNY/ton.
Ukusebenzisa Amanzi Amdaka Kwakhona Ukunciphisa Uthuli:
Iimpompo zifakelwe ezantsi kwe-clarifier ukuze zithumele inxalenye yamanzi amdaka kwiindawo zokugcina uthuthu ukuze kuxutywe kwaye kufume.
Isiphumo: Uxinzelelo olunciphileyo kwindawo yokulahla inkunkuma kodwa oko kwakhokelela ekubeni kubekho ukungcoliseka okuphezulu kunye nokungathotyelwa kwemigangatho yokukhupha inkunkuma.
4. Amanyathelo okuphucula ngoku
Ngenxa yemithetho engqongqo yokusingqongileyo, kwafuneka ukuphuculwa kwenkqubo ngakumbi.
4.1 Uhlengahlengiso lweeKhemikhali kunye nokusebenza rhoqo
Ukugcina i-pH iphakathi kwe-9–10 ngokunyusa umthamo weekhemikhali:
Ukusetyenziswa kwemihla ngemihla: ilayimu (45 kg), ii-coagulants (75 kg), kunye nee-flocculants.
Kuqinisekiswe ukuba kukhutshwa amanzi acocekileyo angama-240 m³/ngosuku emva kokusebenza kwenkqubo ngamaxesha athile.
4.2 Ukutshintsha Ithanki Yodaka Olungxamisekileyo
Ukusetyenziswa kabini kwetanki yongxamiseko:
Ngexesha lokungasebenzi: Ukugcinwa kwedaka.
Ngexesha lokusebenza: Ukususwa kwendalo ukuze kukhutshwe amanzi acocekileyo.
Ukuphucula:
Kongezwe iivalvu kunye nemibhobho kumanqanaba ahlukeneyo eetanki ukuze kube lula ukusebenza okuguquguqukayo.
I-gypsum etshisiweyo yabuyiselwa kwinkqubo ukuze ikhutshwe amanzi okanye isetyenziswe kwakhona.
4.3 Utshintsho olupheleleyo lweNkqubo
Ukunciphisa uxinano lwezinto eziqinileyo emanzini amdaka angenayo ngokubuyisela i-filtrate kwiinkqubo zokukhupha amanzi kwi-vacuum belt ukuya kwi-wastewater buffer tank.
Ukuphucula ukusebenza kakuhle kwe-sedimentation ngokunciphisa amaxesha okuhlala kwendalo ngokulinganisa iikhemikhali kwiitanki ezingxamisekileyo.
5. Iingenelo zokuphucula
