Ukususwa kwe-flue gas emshinini wokuhluza kunciphisa izingozi zemvula ene-asidi kanye nokuthuthukisa ikhwalithi yomoya. Ukuze kuthuthukiswe ukusebenza kahle kanye nokonga izindleko, inani le-desulfurizer kufanele livumelane nezindinganiso eziqinile. Ukususwa kwe-sulfurizer yendabuko kuncike ekulungisweni ngesandla noma ezilinganisweni ezihleliwe, okusho amaphutha angenakugwenywa kanye nochungechunge lwemfucuza.
Ukusetshenziswa kwamamitha obuningi obungaphakathi kuyisiqinisekiso sokulawulwa okunembile kwe-desulfurizer ngesikhathi sangempela, kunciphisa izindleko zokusebenza, ukusetshenziswa kwamakhemikhali kanye nokusetshenziswa okwengeziwe kwemvelo.
Izinselele Ekuhlanzeni Igesi Yokuhlanza Amapayipi
Inselele enkulu ekuhlanzeni igesi yokuhlanza igesi itholakala ekulawuleni okunembile umthamo wama-desulfurizers. Ama-desulfurizers afana ne-lime, i-sodium hydroxide noma amanye asabela nama-sulfur compounds kugesi yokuhlanza bese ekhiqiza imikhiqizo ehlobene nayo. Umthamo we-desulfurizer uncike ekuqoqweni okuthile kwama-sulfur compounds ekukhishweni kwegesi.
Noma kunjalo, igesi yomoya ongcolile ezinguqukweni ezishintshashintshayo yenza kube nzima kwezobuchwepheshe ukunquma ukuhlushwa kwama-desulfurizer ngokunembile. Inani le-desulfurizer lizoba ngaphezulu noma linganele, futhi lezo zimo ezimbili ziholela emiphumeleni ehambisanayo enkambisweni ye-desulfurization. Ake singene kulezo zimo ezimbili ngokuningiliziwe.
Ukungena ngokweqile kwe-desulfurizer kuma-compounds esibabule kuholela ekwandeni kwezindleko, ikakhulukazi ekucutshungulweni okukhulu. Ngaphezu kwalokho, ukukhishwa ngokweqile kwe-sulfurizer kudala ukugcwala okuphezulu koketshezi olune-asidi kanye namanzi angcolile angadingekile, okubangela izindleko ezengeziwe zokwelashwa kwamanzi angcolile. Okokugcina kodwa okubaluleke kakhulu, ukukhishwa ngokweqile kwe-desulfurizer kwandisa izingozi zokugqwala emapayipini nakumadivayisi, bese kuthi uketshezi olune-asidi oluningi kakhulu luholele ekuvameni okuphezulu kokugcinwa nokufakwa esikhundleni.
Ngokuphambene nalokho, ama-desulfurizers anganele anciphisa ukusebenza kahle kwenqubo yokususa i-sulfur, ngakho-ke ama-compounds esibabule ahlala kugesi ophumayo ngesilinganiso esithile. Kuvele ukuthi ahlulekile ukuhlangabezana nezindinganiso zokukhishwa komoya, okudala imiphumela emibi kokubili ekukhiqizweni kokuphepha kanye nokuhambisana nemithethonqubo yezemvelo.
Izinzuzo Zamamitha Obuningi Obungaphakathi
Ukuze kwandiswe ukusebenza kahle komsebenzi ophindaphindwayo futhi kuncishiswe amaphutha angadingekile enziwe ngesandla, amamitha okuqina angaphakathi angenye yezinketho ezinhle kakhulu ekucutshungulweni kwezimboni okusebenzayo. Ukulandela izinzuzo ezisobala konke kuyizizathu zokukhetha amamitha okuqina anembile aku-inthanethi.
Ukulawula Okunembile Inani Lama-Desulfurizer
I-desulfurizer isabela nama-sulfur compounds enqubweni yoku-desulfurization ngokuhambisana nemithetho eqinile. Ubuningi boketshezi loku-desulfurization buyashintsha njengoba ukwehla kokuhlushwa kwama-sulfur compounds ngendlela evamile.
Ukuguquguquka kobuningi kubhekwa njalo futhi kudluliselwa ohlelweni lokuqoqwa kwedatha ngezibonakaliso zikagesi, okwenza ukulungiswa kwesikhathi sangempela kube nokwenzeka ngokulawula izinga lokususwa kwamakhemikhali esibabule. Imitha yobuningi ehlakaniphile eku-inthanethi iyakwazi ukwandisa noma ukunciphisa ama-desulfurizers engeziwe ngokuya ngobuningi ngokuzenzakalelayo, ivimbele ukusetshenziswa ngokweqile noma ukungalingani ngokwanele komthamo.
Ukusebenza Kahle Kokusabela Okuthuthukisiwe kanye Nokuncishiswa Kwemfucuza
Ngokulawula ngokunembile umthamo we-ejenti yokususa i-sulfurizing, imitha yobuningi iqinisekisa ukuthi inqubo yokususa i-sulfuri iphumelela ngangokunokwenzeka, kuyilapho inciphisa imfucuza yamakhemikhali engadingekile. Lokhu, nakho, kunciphisa izindleko zokusebenza.
Ukwehlisa Amathonya Emvelweni
Imitha yokulinganisa ubuningi ehlakaniphile inciphisa izindleko zokusebenza kanye nenani lamakhemikhali ayingozi akhishwa emoyeni. Ngokunciphisa umthwalo wokwelashwa kwamanzi angcolile, ukungcola kwamakhemikhali emanzini angcolile kuncishiswa kakhulu. Ngesikhathi esifanayo, izingozi zokungcola komoya nazo ziyancishiswa.
Ukuzivumelanisa nezimo okuphawulekayo nezimo zokusebenza ezishintshayo
Ukwakheka kwegesi yokuhlanza igesi kuyinkimbinkimbi, futhi izimo zokushisa kanye nengcindezi ziyashintshashintsha kakhulu. Amamitha obuningi be-inthanethi ohlobo lokufakwa ngokuvamile aklanyelwe ukumelana namazinga okushisa aphezulu, ukucindezeleka okuphezulu, kanye nezindawo ezigqwalisayo, okuqinisekisa ukusebenza okuzinzile kanye nokuqoqwa kwedatha okunembile ngaphansi kwalezi zimo eziyinselele.
Izicelo
Ukususwa kwegesi yomoya (i-FGD) kusetshenziswa kabanzi e-flue gas desulfurizationokushiswa ngamalahleorizitshalo zikagesi ezishiswa ngowoyelaImitha yobuningi eku-inthanethi ingasetshenziswa kula mapayipi alandelayo:
Umugqa wokukhiqiza i-lime slurry
Ukondla i-limestone slurry ku-Absorber
Umugqa wokujikeleza kwe-Gypsum ku-Absorber
Umugqa we-calcium sulfite slurry ofinyelela ku-oxidizer
Iluphu yokuzikhipha amanzi nge-Gypsum
Ukufakwa
Iimitha yobuningi eku-inthanethiingafakwa ngokufaka okulula kunokuvala uhlelo kanye nokwakhiwa kabusha kwamapayipi. Ngaphandle kwalokho, iyatholakala ukuze isetshenziswe ngezinto eziningi ezimanzi. Imitha ngayinye ingafakwa epayipini eliqondile lapho udaka lugeleza phezulu. Ukufakwa nge-engeli enjalo kungavikela amathayi adlidlizayo ekudakeni okukhukhulayo ngenkathi kulinganiswa izinto ezintsha ezigelezayo ukuze kugcinwe ukunemba kwayo.
Sekukonke, amakhasimende ayazuza kumamitha obuningi aku-inthanethi kulezi zici ezilandelayo:
1. Ukufakwa okulula nokungabizi kakhulu - Kunciphisa izindleko zemishini zibe cishe u-$500-$700 ngemitha
2. Ukulawulwa okuthuthukisiwe kwe-Calcium Carbonate - lawo mamitha abiza ukwenza ngcono inqubo kanye nezinto zokusetshenziswa.
3. Isikhathi eside sokuphila kwe-Density Meter - Izindleko zokulungisa nokusebenza zehle kakhulu ngenxa yokumelana noketshezi olunamandla.
Ukusetshenziswa kwamamitha obuningi obufakwe ku-inthanethi ezinqubweni zokususa igesi ephuma emshinini wokuhluza kubonakale kuyisisombululo esisebenzayo sokubhekana nezinselele ezifana nokusetshenziswa ngokweqile kwama-ejenti okususa i-sulfuri, izindleko zokusebenza ezikhuphukayo, kanye nokungcola kwemvelo. Ngokubheka izinguquko zobuningi ngesikhathi sangempela, amamitha obuningi avumela ukulawulwa okunembile komthamo wama-ejenti okususa i-sulfuri, ukuthuthukisa ukusebenza kahle kwenqubo yokususa i-sulfuri, ukunciphisa imfucuza, kanye nokunciphisa umthelela emvelweni. Lobu buchwepheshe abugcini nje ngokuthuthukisa ukusetshenziswa kwama-ejenti amakhemikhali kodwa futhi bunegalelo ekunciphiseni izindleko kanye nokusimama kwemvelo, okwenza kube ithuluzi eliwusizo emisebenzini yokuhlanza yanamuhla.
