Kwaziwa kahle ukuthi ama-slurries ohlelweni lwe-desulfurization abonisa kokubili izakhiwo ezilimazayo nezilimazayo ngenxa yezakhiwo zamakhemikhali eziyingqayizivele kanye nokuqukethwe okuphezulu okuqinile. Kunzima ukukala ukuminyana kwe-limestone slurry ngezindlela zendabuko. Ngenxa yalokho, izinkampani eziningi zingase zinamathele enkingeni lapho zikhetha i-limestone slurry. Njengamanje, izilinganiso zokuminyana eziyinhloko zifinyezwa ngezindlela ezintathu ezilandelayo:
1.Differential pressure density imitha;
2.Liquid level transmitter;
3.I-Coriolis mass flow meter.
Isilinganiso sokuminyana kwe-limestone slurry ezinhlelweni ze-desulfurization ngokusebenzisa imitha yokugeleza okukhulu kungenxa yokufana kwesakhiwo semitha yokugeleza kwesisindo kanye nemitha yeshubhu elidlidlizayo. Ishubhu yokulinganisa idlidliza ngemvamisa ethile ye-resonant ngendlela eqhubekayo. Imvamisa yokudlidliza yeshubhu lokudlidliza iyahlukahluka uma igcwele uketshezi lokuminyana okuhlukahlukene.
Sengiphetha, ukuvama kweshubhu elidlidlizayo kubonisa ukuminyana koketshezi oluhambisanayo. Kuyindlela yokuqala kuslurrydehlalaymeasurinto ngokunemba kwayo okuphezulu kanye nebanga elibanzi lokuminyana kwama-slurries. Lezi zindaba ezilandelayo kufanele zibekwe iso ukuze zivumelane nezimo ngokugcwele ezidingweni zesayithi.
Uma ufaka idivayisi iqonde phezulu noma ivundlile, ishubhu yokulinganisa kufanele ibheke phezulu ukuze ivikeleke ekunqwabelaneni kwezinsalela eziqinile, ezingase ziguqule imvamisa yeshubhu futhi ngaleyo ndlela kuthinte ukunemba kwesilinganiso sokuminyana. Uma usebenzisa imitha yokugeleza kwesisindo se-Coriolis ukuze kukale ukuminyana, umthelela wezinga lokugeleza noma isivinini sokugeleza kumitha yokugeleza kwesisindo ngokuvamile awanakwa. Nakuba izinga lokugeleza le-medium elidlula kumitha yokugeleza kwenqwaba lingathinti ngokuqondile isilinganiso sokuminyana, ukugeleza kwesivinini esikhulu sodaka lwe-limestone kungabangela ukuguga okuphawulekayo kushubhu yokulinganisa yemitha yokugeleza kwenqwaba, ngaleyo ndlela kube nomthelela empilweni yayo yesevisi. Ngakho-ke, kuhle ukugcina izinga lokugeleza ngemitha yesisindo liphansi ngangokunokwenzeka ukuze kunwetshwe isikhathi eside futhi kunciphise izindleko.
Faka imitha yesisindo ku-bypass uma izinga lokugeleza epayipini elikhulu liphezulu kakhulu futhi ulungise izinga lokugeleza ngevalvu ukuze uvimbele ukuguga okungenzeka. Akufanele ifakwe ngokuqondile lapho kuphuma ipayipi lokungenisa umoya mpo kodwa kuhlangothi lokucindezela lwephampu (ukugwema ukucindezela okuphansi). Ngenxa yokwakheka kwezinto, ukuguga, nokugqwala, ukwakheka kokusebenza kweshubhu lokulinganisa kuzoshintsha ngemva kokusebenza isikhathi eside, futhi imvamisa yayo ezwakalayo izothintwa yilezi zici, okuzophumela ekuncipheni kokulinganisa ukunemba kokuminyana. Ukulungiswa kabusha kwenkundla nokulungiswa kuyadingeka. Ngaphambi kokuvaleka isikhathi eside, ipayipi kufanele ligezwe ngamanzi ahlanzekile ukuze kuvinjwe i-limestone ukuthi inganamatheli eshubhuni elingaphakathi noma ngisho nokuvimba ipayipi, okungase kuholele ekwehliseni ukunemba kokulinganisa noma ngisho kwenze ukukala kungenzeki.
Uketshezi lwe-viscous kanye nezinhlayiya eziqinile kuketshezi olulinganisiwe kubangela ukuguga ngaphakathi kweshubhu elidlidlizayo lemitha yokugeleza kwe-Coriolis mass. Isimo sokuguga seshubhu elidlidlizayo sinomthelela othile ekulinganisweni okungaxhunyiwe ku-inthanethi kwemitha yokugeleza, ukuhlonzwa kwephutha, nesilinganiso esisekelwe ekudlidlizeni se-viscosity yoketshezi. Ukuguga kwepayipi okubangelwa izinhlayiya eziqinile kungaholela ekuhlulekeni ngokushesha kwemitha yokugeleza okukhulu.
Ngokungqubuzanayo,I-ultrasonic density metresngokusekelwe kumgomo we-acoustic impedance awathintwa ukugqokwa kwezinhlayiyana ezinjalo. Ngakho-ke, inokuphila kwesevisi ende kakhulu futhi ayithinteki ukuguga okuvela ezinhlayiyeni eziku-slurry. Sicela uxhumaneI-Lonnmeterokwamanje futhi ucele ukucaphuna kwamahhala uma udidekile nganoma iyiphi inkinga.
