Kusetshenziswa uhlelo lwesikhungo samandla esibaselwe ngamalahle njengesibonelo, i-flue gas desulfurization (FGD) uhlelo, lokhu kuhlaziya kuhlola izindaba ezinhlelweni ezijwayelekile zamanzi angcolile e-FGD, njengedizayini embi kanye namazinga aphezulu okuhluleka kwemishini. Ngokulungiswa okuningi nokulungiswa kwezobuchwepheshe, okuqukethwe okuqinile emanzini angcolile kuye kwancishiswa, okuqinisekisa ukusebenza okujwayelekile kwesistimu nokwehliswa kwezindleko zokusebenza nokulungisa. Izisombululo ezisebenzayo kanye nezincomo zahlongozwa, zanikeza isisekelo esiqinile sokufeza ukungabikho kokukhishwa kwamanzi angcolile esikhathini esizayo.
1. Uhlolojikelele Lwesistimu
Izitshalo zamandla asetshenziswa ngamalahle ngokuvamile zisebenzisa inqubo ye-FGD ye-limestone-gypsum wet, esebenzisa i-limestone (CaCO₃) njengesimunyiso. Le nqubo ikhiqiza ngokungenakugwenywa amanzi angcolile e-FGD. Kulesi simo, izinhlelo ezimbili ezimanzi ze-FGD zabelana ngeyunithi eyodwa yokuhlanza amanzi angcolile. Umthombo wamanzi angcolile ukuchichima kwe-gypsum cyclone, kusetshenzwe kusetshenziswa izindlela zendabuko (uhlelo lwamathangi amathathu) elinomthamo oklanyelwe ongu-22.8 t/h. Amanzi angcolile alungisiwe aphonswa amakhilomitha ayisi-6 ukuya endaweni yokulahla ukuze kuncishiswe uthuli.
2. Izinkinga Ezinkulu Ohlelweni Lwangempela
I-diaphragm yamaphampu emithamo ivamise ukuvuza noma yehluleke, kuvimbele ukuthakwa kwamakhemikhali okuqhubekayo. Amazinga aphezulu okuhluleka komshini wokuhlunga amapuleti nohlaka kanye namaphampu odaka andisa izimfuno zabasebenzi futhi akhinyabeza ukukhishwa kodaka, anciphisa ukuthungwa kwenhlabathi ezintweni ezicacisayo.
Amanzi angcolile, asuka ekuchichimeni kwesishingishane se-gypsum, abe nokuminyana okungaba ngu-1,040 kg/m³ nokuqukethwe okuqinile okungu-3.7%. Lokhu kukhinyabeze ikhono lesistimu lokuqhubeka nokukhipha amanzi ahlanzekile nokulawula ukugxiliswa kwe-ion eyingozi kusixhumi.
3. Izinguquko Zokuqala
Ukuthuthukisa Umthamo Wamakhemikhali:
Kwafakwa amathangi amakhemikhali engeziwe phezu kwesistimu ye-triple-tank ukuze kuqinisekiswe ukulinganisa okungaguquguquki ngokusebenzisa amandla adonsela phansi, alawulwa yi-imitha yokuhlushwa eku-inthanethi.
Umphumela: Izinga lamanzi elithuthukisiwe, nakuba i-sedimentation isadingeka. Ukukhishwa kwansuku zonke kwehliselwe ku-200 m³, obekunganele ekusebenzeni okuzinzile kwezinhlelo ezimbili ze-FGD. Izindleko zokuthatha umthamo beziphezulu, isilinganiso esingu-12 CNY/ton.
Ukusebenzisa kabusha Amanzi Angcolile Ukucindezela Uthuli:
Amaphampu afakwe ngezansi ukuze kuqondiswe kabusha ingxenye yamanzi angcolile eziseleni zomlotha ezisendaweni ukuze zixutshwe futhi ziswanyiswe.
Umphumela: Ukuncipha kwengcindezi endaweni yokulahla kodwa kuholele ekudakaleni okuphezulu kanye nokungalandelwa kwezindinganiso zokulahla.
4. Izinyathelo Zamanje Zokuthuthukisa
Ngemithetho eqinile yezemvelo, ukuthuthukiswa kwesistimu okwengeziwe kwakudingeka.
4.1 Ukulungiswa Kwamakhemikhali kanye Nokusebenza Okuqhubekayo
I-pH igcinwe phakathi kuka-9-10 ngokunyuka kwamakhemikhali amakhemikhali:
Ukusetshenziswa kwansuku zonke: umcako (45 kg), ama-coagulants (75 kg), nama-flocculants.
Ukuqinisekisa ukukhishwa kwamanzi angu-240 m³/ngosuku ngemva kokusebenza kwesistimu ngezikhathi ezithile.
4.2 Ukulungisa kabusha Ithangi Le-Emergency Slurry Tank
Ukusetshenziswa kabili kwethangi lezimo eziphuthumayo:
Ngesikhathi sokuphumula: Isitoreji se-slurry.
Ngesikhathi sokusebenza: Ukufakwa kwenhlabathi yemvelo ukuze kukhishwe amanzi ahlanzekile.
Ukuthuthukisa:
Kungezwe ama-valve namapayipi kumazinga ahlukahlukene amathangi ukuze kusebenze ukusebenza okuguquguqukayo.
I-gypsum enenhlabathi ibuyiselwe ohlelweni ukuze ikhishwe amanzi noma iphinde isetshenziswe.
4.3 Izinguquko Zohlelo Olubanzi
Kwehliswe ukugxila kokuqinile emanzini angcolile angenayo ngokuqondisa kabusha i-filtrate kusuka kumasistimu okuqeda amanzi ebhande le-vacuum kuya ethangini lesivikeli samanzi angcolile.
Kuthuthukiswe ukusebenza kahle kwe-sedimentation ngokunciphisa izikhathi zokuzinza zemvelo ngokusebenzisa umthamo wamakhemikhali emathangeni aphuthumayo.
5. Izinzuzo Zokuthuthukisa
Amandla athuthukisiwe:
Ukusebenza okuqhubekayo nokuphuma kwansuku zonke kwamanzi angcolile angaphezu kuka-400 m³ athobelayo.
Ukulawulwa okusebenzayo kwe-ion ku-absorber.
Imisebenzi eyenziwe Lula:
Kuqedwe isidingo sokucindezela isihlungi sepuleti-nohlaka.
Ukuncishiswa komsebenzi wokuphatha udaka.
Ukuthembeka Kwesistimu Okuthuthukisiwe:
Ukuvumelana nezimo okukhulu ezinhlelweni zokucubungula amanzi angcolile.
Ukuthembeka okuphezulu kwemishini.
Ukonga Izindleko:
Ukusetshenziswa kwamakhemikhali kwehliselwe ku-lime (1.4 kg/t), ama-coagulants (0.1 kg/t), nama-flocculants (0.23 kg/t).
Izindleko zokwelashwa zehliselwe ku-5.4 CNY/ton.
Ukonga ngonyaka cishe kwe-948,000 CNY ezindlekweni zamakhemikhali.
Isiphetho
Ukwenziwa kahle kohlelo lwamanzi angcolile lwe-FGD kuholele ekuthuthukisweni kokusebenza kahle, ukunciphisa izindleko, kanye nokuhambisana nezindinganiso eziqinile zemvelo. Lezi zinyathelo zisebenza njengereferensi yezinhlelo ezifanayo ezifuna ukuzuza ukungabikho kokukhishwa kwamanzi angcolile kanye nokusimama kwesikhathi eside.
