FGD spray nozzles

Pamalo a Blue Sky Defense Battle, pali 'bwanamkubwa wodziwika' yemwe amayang'anira mwakachetechete thanzi lathu la kupuma - si nsanja yayikulu yolowera kapena njira yovuta yowongolera, komaflue gas desulfurization nozzle (FGD spray nozzle)ndi m'mimba mwake ma millimeters ochepa chabe - gawo laling'ono losawoneka bwino ndilo phata la mphamvu ya dongosolo lonse la desulfurization.
Monga "pakhosi" la desulfurization system, mphunoyo iyenera kupirira "mayeso atatu" a kutentha kwakukulu, dzimbiri lamphamvu, ndi kuvala kwambiri. Zida zachitsulo zachikhalidwe nthawi zambiri zimakhala ndi mavuto monga kukula kwa pore kukula ndi kulephera kwa atomization pambuyo pa miyezi ingapo ya kukokoloka kwa acidic slurries; Ngakhale kuti mapulasitiki a uinjiniya sachita dzimbiri, ndi ovuta kupirira kutentha kosalekeza. Panthawiyi, kupambana kwakukulu kuchokera ku sayansi yamakono - reaction sintered silicon carbide ceramics, ndikulembanso miyezo yamakampani.
Mtundu watsopano wa ceramic uwu, womwe umadziwika kuti "golide wakuda wamafakitale," umakhala ndi mawonekedwe odabwitsa pamlingo wocheperako: mamiliyoni ambiri a silicon carbide makhiristo amapanga netiweki wandiweyani kudzera munjira zapadera za sintering, ndikupanga kuuma kofanana ndi diamondi. Pamene desulfurization slurry munali gypsum particles ndi flushed pa kuthamanga kwambiri ndi liwiro, mavalidwe ake mlingo ndi otsika kwambiri kuposa zitsulo wamba. Chofunika kwambiri, ili ndi "mphamvu" yachilengedwe yolimbana ndi asidi ndi dzimbiri za alkali, ndipo imatha kusunga thupi lake losawonongeka ngakhale pansi pa kusinthasintha kwakukulu kwa pH.

Pankhani ya bata, nkhaniyi ikuwonetsa moyo wautumiki wodabwitsa. Kupatuka kwa mbali ya atomization kwa nozzle yazinthu izi kumayendetsedwabe pang'onopang'ono pakatha zaka zingapo, ndipo kuthekera kosunga bwino uku kumawonjezera kukonzanso kwa zida kangapo.
Kwa makasitomala omwe amafunikira kugwiritsa ntchito machitidwe a desulfurization, kusankha ma silicon carbide nozzles kuli ngati kugula "inshuwaransi ya moyo wonse" pazida. Sizimangochepetsa mtengo wa zida zosinthira, koma koposa zonse, zimatsimikizira kukhazikika kwachangu kwa desulfurization - zomwe zimagwirizana mwachindunji ndi miyezo yachitetezo cha chilengedwe komanso kupanga mabizinesi mosalekeza.
Zigawo za nozzles zomwe zimapangidwa pogwiritsa ntchito ukadaulo waukadaulo wamakina odziwika bwino zimayesedwa mwamphamvu kangapo, kuphatikiza kuyesa kwa atomization, musanachoke kufakitale kuti zitsimikizire kuti zabwino zomwe zidapangidwazo zimasinthidwa kukhala zopindulitsa zachilengedwe.
Paulendo watsopano wotsogozedwa ndi cholinga cha "dual carbon", luso lazopangapanga likulowetsa mphamvu zosatha mu zida zoteteza chilengedwe. Kugwiritsiridwa ntchito kofala kwa sintered silicon carbide ceramic nozzles ndi mawu am'munsi omveka bwino pakusintha kwazinthu zomwe zimathandizira kupanga zobiriwira. Tikayang'ana kumwamba koyera kwa buluu, tikhoza kuganiziranso za "oyang'anira ceramic" awa omwe abisa luso lawo ndi kutchuka kwawo - akuyang'anira chiyero cha mamita zikwi ndi kupirira kwa millimeter.
