Kusetyenziswa inkqubo yomatshini wombane we-flue gas desulfurization (FGD) njengomzekelo, olu hlalutyo luphonononga imiba kwiinkqubo zamanzi amdaka esiqhelo ze-FGD, ezifana noyilo olulambathayo kunye namazinga aphezulu okusilela kwezixhobo. Ngokusetyenziswa kwezinto ezininzi kunye nokuguqulwa kobugcisa, umxholo oqinileyo kumanzi amdaka wancitshiswa, uqinisekisa ukusebenza kwenkqubo eqhelekileyo kunye nokunciphisa iindleko zokusebenza kunye nokugcinwa. Izisombululo ezisebenzayo kunye nezindululo zacetywa, zibonelela ngesiseko esiluqilima sokuphumeza ukungabikho kokukhutshwa kwamanzi amdaka kwixesha elizayo.
1. Isishwankathelo seNkqubo
Amaziko ombane asebenzisa amalahle aqhele ukusebenzisa inkqubo ye-limestone-gypsum wet FGD, esebenzisa i-limestone (CaCO₃) njengento yokufunxa. Le nkqubo ivelisa amanzi amdaka e-FGD. Kule meko, iinkqubo ezimbini ezimanzi ze-FGD zabelana ngeyunithi enye yokucoca amanzi amdaka. Umthombo wamanzi amdaka yi-gypsum cyclone overflow, ecutshungulwa kusetyenziswa iindlela zemveli (inkqubo yetanki ezintathu) enomthamo oyiliweyo we-22.8 t / h. Amanzi amdaka acociweyo ampontshwa umgama oyi-6 km ukuya kwindawo yokulahla uthuli.
2. Imiba eMikhulu kwiNkqubo yokuqala
I-diaphragm yeempompo zedosi ihlala ivuza okanye yasilela, ithintela ukujongwa kweekhemikhali okuqhubekayo. Izinga eliphezulu lokungaphumeleli kwi-plate-and-frame filter presses kunye neempompo ze-sludge zandisa iimfuno zabasebenzi kunye nokukhutshwa kodaka, ukucotha intlenga kwii-clarifiers.
Amanzi amdaka, asuka kwinkanyamba yegypsum ephuphumayo, abenoxinano olumalunga ne-1,040 kg/m³ kunye nesiqulatho esiqinileyo se-3.7%. Oku kuphazamisa ukukwazi kwenkqubo ukukhupha ngokuqhubekayo amanzi acociweyo kunye nokulawula ukugxila kwe-ion eyingozi kwi-absorber.
3. Uhlengahlengiso lwangaphambili
Ukuphucula ukudongwa kweMichiza:
Iitanki zekhemikhali ezongezelelweyo zafakelwa phezu kwenkqubo yeitanki ezintathu ukuqinisekisa ukudosa okungaguquguqukiyo ngokuxhuzula, kulawulwa yiimitha yoxinaniso lwe-intanethi.
Isiphumo: Ukuphuculwa komgangatho wamanzi, nangona intlenge isafuneka. Ukukhutshwa kwemihla ngemihla kwehliswe ukuya kwi-200 m³, ebinganelanga ekusebenzeni ngokuzinzileyo kweenkqubo ezimbini ze-FGD. Iindleko zokudosa beziphezulu, i-avareji ye-12 CNY/toni.
Ukuphinda kusetyenziswe amanzi amdaka ukucudisa uthuli:
Iimpompo zafakelwa kumzantsi wesicacisi ukuqondisa ngokutsha indawo yamanzi amdaka kwizisele zothuthu ezikwindawo yokuxutywa kunye nokufuma.
Isiphumo: Uxinzelelo olucuthiweyo kwindawo yokulahla kodwa kusekho nesiphumo sobunzima obuphezulu kunye nokungathotyelwa kwemigangatho yokulahla.
4. Amanyathelo angoku okuPhucula
Ngemigaqo engqongqo yokusingqongileyo, ukuphuculwa kwenkqubo eyongezelelekileyo kwakuyimfuneko.
4.1 Ulungelelwaniso lweMichiza kunye nokusebenza ngokuqhubekayo
I-pH egcinwe phakathi kwe-9-10 ngokunyuka kwedosi yeekhemikhali:
Ukusetyenziswa kwemihla ngemihla: ikalika (45 kg), i-coagulants (75 kg), kunye ne-flocculants.
Ukuqinisekisa ukukhutshelwa kwe-240 m³/ngosuku lwamanzi acocekileyo emva kokusebenza kwenkqubo okwethutyana.
4.2 Ukuhlaziya iTanki yeNgxaki eLudaka oluNgxamisekileyo
Ukusetyenziswa kabini kwetanki likaxakeka:
Ngexesha lokuphumla: Ugcino oluludaka.
Ngexesha lokusebenza: Intlenge yendalo yokutsalwa kwamanzi acwengileyo.
Ukuphucula:
Iivalvu ezongeziweyo kunye nemibhobho kumanqanaba ahlukeneyo etanki ukwenza imisebenzi eguquguqukayo.
Igypsum enentlenga yabuyiselwa kwisistim ukuze igalelwe amanzi okanye iphinde isetyenziswe.
4.3 Uhlengahlengiso olubanzi lweSistim
Ukuthotywa koxinzelelo lweziqina kumanzi amdaka angenayo ngokuthumela ngokutsha isihluzi ukusuka kwiinkqubo zokukhupha amanzi kwibhanti yokufunxa ukuya kwitanki yesithinteli samanzi amdaka.
Ukomelezwa kokusebenza kwentlenga ngokunciphisa amaxesha okuzinzisa kwendalo ngokuthafa kweekhemikhali kwiitanki zikaxakeka.
5. Iinzuzo zokuSebenzisa
Isakhono esiphuculweyo:
Ukusebenza okuthe gqolo nokukhutshelwa kwemihla ngemihla ngaphezulu kwe-400 m³ yamanzi amdaka athobelayo.
Ulawulo lwe-ion olusebenzayo kwi-absorber.
Imisebenzi eyenziwe lula:
Kupheliswe imfuno yokucoca ipleyiti kunye nesakhelo.
Ukuncitshiswa komsebenzi wokuphatha udaka.
Ukuthembeka Kwenkqubo Eyongeziweyo:
Ukuguquguquka okukhulu kwiishedyuli zokusetyenzwa kwamanzi amdaka.
Ukuthembeka kwezixhobo eziphezulu.
Ugcino lweendleko:

Iindleko zonyango zehliselwe kwi-5.4 CNY/toni.
Ukonga lonyaka malunga ne-948,000 CNY kwiindleko zekhemikhali.
Ukuqukumbela
Ukulungiswa kwenkqubo yamanzi amdaka e-FGD kuphumele ekuphuculeni kakhulu ukusebenza kakuhle, ukunciphisa iindleko, kunye nokuthotyelwa kwemigangatho engqongqo yokusingqongileyo. La manyathelo asebenza njengesalathiso kwiisistim ezifanayo ezifuna ukuphumeza ukungabikho kwamanzi amdaka kunye nozinzo lwexesha elide.
