I-flue gas desulfurization endaweni yokucwenga inesisindo ekwehliseni ubungozi bemvula ene-asidi kanye nokuthuthukisa ikhwalithi yomoya. Ngenhloso yokuthuthukisa ukusebenza kahle nokonga izindleko, inani le-desulfurizer kufanele lilungiswe lifinyelele kumazinga aqinile. I-desulfurization evamile incike ekulungisweni okwenziwa ngesandla noma ekulinganiseni okungaguquki, okusho amaphutha angenakugwemeka kanye nochungechunge lwemfucuza.
Ukusetshenziswa kwamamitha we-inline density kuyisiqinisekiso sokulawulwa okunembile kwe-desulfurizer ngesikhathi sangempela, ukwehlisa izindleko zokusebenza, ukusetshenziswa kwamakhemikhali kanye nokusetshenziswa okwengeziwe kwemvelo.
Izinselelo Ekuhluzeni Igesi Yomkhuhlane we-Flue Desulfurization
Inselele enkulu ekuhluzeni igesi e-flue desulfurization ilele ekulawuleni okunembile umthamo wama-desulfurizer. Ama-desulfurizer afana ne-lime, i-sodium hydroxide noma amanye ahlangana nezinhlanganisela zesulfure ku-flue gas bese ekhiqiza imikhiqizo ehlobene. Umthamo we-desulfurizer uncike ekugxilweni okukhethekile kwezinhlanganisela zesulfure ekukhishweni.
Noma kunjalo, i-flue gas ekushintsheni okuguquguqukayo yenza kube nzima kwezobuchwepheshe ukunquma ukugcwala kwama-desulfurizer ngokunembile. Inani le-desulfurizer lizoba ngokwedlulele noma linganele, futhi lezo zimo ezimbili ziholela emiphumeleni ehambisanayo ohlelweni lwe-desulfurization. Ake singene kulezo zimo ezimbili ngokuningiliziwe.
I-desulfurizer eyeqile ingena ezinhlanganisela zesulfure iphumela ekwenyukeni kwezindleko, ikakhulukazi ekucutshungulweni okukhulu. Ngaphezu kwalokho, i-desulfurization ngokweqile idala ukugcwala okuphezulu koketshezi olune-asidi namanzi alahlwayo angadingekile, okubangela izindleko ezengeziwe zokuhlanza amanzi angcolile. Okokugcina, ama-desulfurizer eqile akhulisa izingozi zokugqwala kwamapayipi nemishini, bese uketshezi olune-asidi engaphezulu lungaholela emazingeni aphezulu okugcinwa nokushintshwa.
Ngokuphambene nalokho, ama-desulfurizer anganele anciphisa ukusebenza kahle kwenqubo ye-desulfurization, ngakho-ke ama-sulfur compounds ahlala ku-flue gas endaweni ethile. Kuvele ukuthi yehlulekile ukuhlangabezana nezindinganiso ezikhishwayo, okudale imiphumela engemihle kukho kokubili ukukhiqizwa kokuphepha kanye nokuhambisana nemithetho yemvelo.
Izinzuzo ze-Inline Density Meters
Ukuze kwandiswe ukusebenza kahle komsebenzi ophindaphindiwe futhi kuncishiswe amaphutha angadingekile enziwa ngesandla, amamitha okuminyana emgqeni angenye yezindlela ezingcono kakhulu zokucutshungulwa kwezimboni. Ukulandela izinzuzo ezisobala zonke izizathu zokukhetha amamitha wokuminyana aku-inthanethi anembile.
Ukulawula Okunembile Ngenani Lama-Desulfurizer
I-desulfurizer isabela nezinhlanganisela zesulphur ohlelweni lwe-desulfurization ngokuhambisana nemithethonqubo eqinile. Ukuminyana koketshezi lwe-desulfurization kushintsha njengoba ukuncipha kokuhlangana kwe-sulfur compounds evamile.
Ukushintshashintsha kokuminyana kubhekwa ngokuqhubekayo futhi kudluliselwe ohlelweni lokuqoqa idatha kumasignali kagesi, okwenza ukulungiswa kwesikhathi sangempela kwenzeke ngokulawula izinga lokususwa kwezinhlanganisela zesulfure. Imitha yokuminyana eku-inthanethi ehlakaniphile iyakwazi ukukhulisa noma ukwehlisa ama-desulfurizer angeziwe ngokuya ngokuminyana ngokuzenzakalelayo, ukuvimbela ukusetshenziswa ngokweqile noma ukulinganisa okunganele.
Ukusebenza Okuthuthukisiwe Kwezokusabela kanye Nokungcola Okuncishisiwe
Ngokulawula kahle umthamo we-ejenti ye-desulfurizing, imitha yokuminyana iqinisekisa ukuthi inqubo ye-desulfurization isebenza kahle ngangokunokwenzeka, kuyilapho inciphisa ukungcola okungadingekile kwamakhemikhali. Lokhu-ke kwehlisa izindleko zokusebenza.
Ukwehlisa Amathonya Kwezemvelo
Imitha yokuminyana ehlakaniphile inciphisa izindleko zokusebenza kanye nenani lamakhemikhali ayingozi akhishelwa emoyeni. Ngokwenza lula umthwalo wokuhlanza amanzi angcolile, ukungcoliswa kwamakhemikhali emanzini angcolile kuncipha kakhulu. Ngesikhathi esifanayo, izingozi zokungcoliswa komoya ziyehliswa, futhi.
Ukuzivumelanisa nezimo Okuvelele Ekushintsheni Izimo Zokusebenza
Ukwakheka kwegesi ehluzwayo yokuhlunga kuyinkimbinkimbi, futhi izimo zokushisa nezingcindezi ziyashintshashintsha kakhulu. Amamitha okuminyana aku-inthanethi ohlobo lokufaka ngokuvamile aklanyelwe ukumelana nezinga lokushisa eliphezulu, ukucindezela okuphezulu, nendawo ebolayo, iqinisekisa ukusebenza okuzinzile nokuqoqwa kwedatha okunembile ngaphansi kwalezi zimo eziyinselele.
Izinhlelo zokusebenza
I-flue gas desulfurization (FGD) isetshenziswa kabanzi kuezibaselwe ngamalahleorizitshalo zamandla ezishiswe ngamafutha. Imitha yokuminyana eku-inthanethi ingasetshenziswa kula mapayipi alandelayo:
Umugqa wokukhiqiza i-limestone slurry
Okuphakelayo kwe-limestone slurry ku-Absorber
Umugqa we-Gypsum recirculation ku-Absorber
Ulayini we-calcium sulfite slurry ofinyelela ku-oxidizer
Gypsum self-drain loop
Ukufakwa
Iimitha yokuminyana ku-inthanethiingafakwa ngokufaka kalula esikhundleni sokuvala isistimu nokwakhiwa kabusha kwamapayipi. Ngaphandle kwalokho, iyatholakala kuhlelo olubanzi lwezinto ezimanzi. Imitha ngayinye ingafakwa epayipini eliqondile eligeleza libheke phezulu. Ukufakwa ku-engeli enjalo kungavikela izintambo ezidlidlizayo ku-slurry abrasive ngenkathi kukalwa into entsha egelezayo ukuze kugcinwe ukunemba kwayo.
Sekukonke, amakhasimende ayazuza kumamitha wokuminyana aku-inthanethi kulezi zici ezilandelayo:
1. Ukufakwa okulula nokushibhile - Kwehlisa izindleko zokusebenzisa izinsimbi zibe cishe u-$500-$700 imitha ngayinye
2. Ukulawulwa okuthuthukisiwe kweCalcium Carbonate - lawo mamitha abiza ukukhulisa inqubo kanye nempahla eluhlaza.
3. Ukuphila okunwetshiwe kwe-Density Meter - Izindleko zokunakekela nokusebenza zehliswe kakhulu ngenxa yokumelana noketshezi olunamanzi.
Ukusetshenziswa kohlobo lokufakwa kwamamitha okuminyana ku-inthanethi ezinqubweni zokuhlanza igesi ecwengiwe kubonakale njengesixazululo esisebenzayo sokubhekana nezinselele ezifana nokusetshenziswa kwe-ejenti ye-desulfurizing ngokweqile, ukukhuphuka kwezindleko zokusebenza, kanye nokungcoliswa kwemvelo. Ngokuqapha izinguquko zokuminyana ngesikhathi sangempela, amamitha okuminyana anika amandla ukulawula okunembile kwesilinganiso se-ejenti ye-desulfurizing, ukuthuthukisa ukusebenza kahle kwenqubo ye-desulfurization, ukunciphisa imfucuza, kanye nokunciphisa umthelela wemvelo. Lobu buchwepheshe abugcini nje ngokuthuthukisa ukusetshenziswa kwama-ejenti amakhemikhali kodwa futhi bufaka isandla ekwehliseni izindleko kanye nokusimama kwemvelo, okubenza kube ithuluzi elibalulekile lemisebenzi yokucwenga yesimanje.
