Ma inline density mita ndi omwe amasintha kwambiri ntchito yochotsa ma nitration m'mafakitale opangira magetsi panthawi ya mafakitale. Ma geji anzeru awa anzeru amalola ogwiritsa ntchito kuyang'anira kuchuluka kwa magetsi nthawi yeniyeni, komanso zida zofunika kwambiri pothana ndi zovuta za mankhwala. Ndikofunikira kuti ogwira ntchito akumane ndi zovuta zogwirira ntchito monga kutsatira malamulo okhwima kwambiri okhudza chilengedwe. Yang'anani mwatsatanetsatane momwe amagwirira ntchito kuti athetse mavuto ovuta a mafakitale ndikuchotsa ntchito yovuta koma yobwerezabwereza.
Mavuto Ovuta Aukadaulo mu Denitration
Kusintha kwa mpweya woipa wa nitrogen oxide (NOx) si ntchito yophweka. Nitrogen oxide sinathe kuthetsedwa kwathunthu, kaya m'mafakitale opangidwa ndi malasha, otenthedwa ndi mafuta kapena ngakhale biomass. Kuwongolera mpweya woipa molondola kumakhudzana ndi Selective Catalytic Reduction (SCR) kapena Selective Non-Catalytic Reduction (SNCR), momwe ma reagents amawonjezedwa mu flue gas stream kuti achitepo kanthu. Komabe, kuyang'anira molondola mlingo nthawi yeniyeni kumakumana ndi zovuta zambiri kuchokera ku zovuta zogwirira ntchito. Kusalondola pakuyeza kungayambitse kutayika kwa ammonia ndi zinyalala za ma reagents.
Lonnmeter imapanga ndikupanga mita yoyezera kuchuluka kwa anthukuti muyeze nthawi zonse kuti mupewe zolakwika za anthu pa zitsanzo zachikhalidwe. Kuyesa kwa anthu kumadalira kwambiri kufufuza nthawi ndi nthawi ndi kuyerekezera kosalunjika.mita yoyezera kuchuluka kwa anthu pa intanetiimatha kuzindikira kusinthasintha pang'ono pakuwunika kuchuluka kwa magetsi kuti ithandize kusintha kolondola, ndikusunga njira zonse zochotsera magetsi kukhala zokhazikika komanso zogwira mtima.
Kuphatikiza apo, imagwiranso ntchito popereka magawo osonyeza khalidwe losakaniza, kusinthasintha kwa reagent komanso kuchuluka kwa madzi. Mwachitsanzo, kusasinthasintha kwa urea stream mpaka kusungunuka m'madzi kumasokoneza kapangidwe ka reaction. Mwa kuyang'anira slurry mwachindunji mu payipi, inline density mita zimaonetsetsa kuti kuchuluka komwe kukufunika kukusungidwa kuyambira kusungidwa mpaka jakisoni, kuchepetsa chiopsezo cha kusagwira ntchito bwino kwa njira kapena kusatsatira malamulo a chilengedwe.
Mamita Olimbikitsidwa a Kachulukidwe ka Mafakitale
Kukonza Makina Odziyimira Pawokha mu Denitration ndi Kudalirika kwa Dongosolo
Masiku omwe ogwira ntchito m'mafakitale ankadalira njira zoyendetsera ntchito pamanja kuti akonze bwino njira zojambulira reagent apita. Ma inline density meters amakono amalumikizana bwino ndi Distributed Control Systems (DCS) kapena Programmable Logic Controllers (PLC), zomwe zimapangitsa kuti pakhale njira yodziwikiratu yodziwikiratu. Pamene kuchuluka kwa density reads kwasiyana ndi zomwe zakonzedweratu, makinawo amangosintha kuchuluka kwa reagent kapena kuchepetsa yankho ngati pakufunika. Automation iyi sikuti imangochepetsa nkhawa kwa ogwira ntchito komanso imachotsa kuchedwa komwe kumachitika chifukwa cha kupanga zisankho kwa anthu.
Ndikofunikira kulinganiza njira zopangira mankhwala pochotsa sulfurization ndi denitration, komwe madzi a laimu ndi ammonia amagwiritsidwa ntchito nthawi imodzi. Kuyang'anira kuchuluka kwa madzi awiriwa ndikofunikira kuti desulfurization ndi denitration zigwire ntchito bwino. Kugwirizana kumeneku kumathandiza kupewa mavuto wamba monga sedimentation m'mapaipi a miyala yamchere kapena kuchuluka kwa ammonia, zomwe zonsezi zingayambitse kutseka kapena kukonza ndalama zambiri.
Kupatula apo, zoyezera mphamvu zamkati zokhazikikazi zimapirira mikhalidwe yovuta kwambiri mufakitale yamagetsi. Kuti mapangidwe apadera athe kupirira kutentha kwambiri ndi kupsinjika, ndi abwino kwambiri kuthana ndi mankhwala owononga m'mikhalidwe yovuta monga makina ochotsera mpweya woipa.
Kugwiritsa Ntchito Ma Inline Density Meters mu Coal-Fire Power Plant
Kawirikawiri, mafakitale opanga magetsi opangidwa ndi malasha akuvutika ndi kusagwira bwino ntchito poyesa kuchuluka kwa madzi ndi mavuto ena okhudzana ndi ukadaulo, kuphatikizapo koma osati kokha kutsekeka kwa mapaipi, kutsetsereka kwa ammonia ndi kukonza komwe kungatheke. Choyezera kuchuluka kwa madzi mu foloko ndi chida chanzeru choyenera kugwiritsa ntchito poika ammonia komanso makina osungunula madzi a limestone.
Zotsatira zake zinali zosintha. Kuwunika kuchuluka kwa madzi nthawi yeniyeni kunathandiza fakitale kukonza bwino kuchuluka kwa madzi a reagent molondola kwambiri. Kuchuluka kwa madzi a ammonia kunatsika ndi 90%, pomwe mphamvu yochepetsera madzi a NOx inapitirira 92%. Madzi a limestone, omwe kale ankayambitsa kukula ndi kutsekeka, adasungidwa bwino kwambiri, kuchotsa kukonza kosakonzedwa komanso kuchepetsa nthawi yogwira ntchito ndi 20%. Kusintha kumeneku sikunangopangitsa fakitaleyo kutsatira miyezo ya chilengedwe komanso kunachepetsa ndalama zogwirira ntchito ndi 15%.
Chifukwa Chake Mamita Okhala ndi Density Ofunika Kwambiri
Chomwe chimasiyanitsa mita yozungulira ndi njira zina zowunikira ndi kusinthasintha kwawo komanso kusinthasintha kwawo. Sikuti zimangogwiritsidwa ntchito pochotsa madzi m'thupi; ntchito zawo zimafikira ku njira iliyonse yamafakitale yomwe imafuna kasamalidwe kabwino ka madzi. Pankhani ya malo opangira magetsi, izi zikuphatikizapo machitidwe ochotsa sulfur, kukonza madzi otayira, ndi ntchito zosakaniza mafuta. Kutha kwawo kupereka deta yeniyeni, yolondola, komanso yogwira ntchito kumawapangitsa kukhala maziko a kukonza njira zamakono.
Mwa kugwiritsa ntchito zida izi, mafakitale opanga magetsi amatha kukwaniritsa njira zowongolera zomwe kale sizinkatheka. Ubwino wake umapitirira kutsata malamulo ndi magwiridwe antchito; umaphatikizaponso kukhalitsa kwa nthawi yayitali kwa zida, kuchepetsa ndalama zosamalira, komanso kukhazikika kwabwino. Kwa ogwira ntchito omwe amaona kuti magwiridwe antchito ndi udindo wawo pa chilengedwe ndi ofunika, mita yoyezera kuchuluka kwa magetsi si ndalama chabe—ndi chinthu chofunikira kwambiri.
Mapeto
Kugwiritsa ntchito mita yoyezera kuchuluka kwa magetsi m'makina oyezera magetsi kukuwonetsa momwe ukadaulo wapamwamba ungasinthire njira zamafakitale. Pothana ndi mavuto monga kusasinthasintha kwa reagent, kutsetsereka kwa ammonia, ndi automation ya njira, zida izi zimathandiza mafakitale amagetsi kugwira ntchito bwino, mokhazikika, komanso mopindulitsa. Mbiri yawo yotsimikizika mu ntchito zenizeni ikuwonetsa kufunika kwawo ngati chida chofunikira kwambiri polimbana ndi mpweya wa NOx. Ngati mukufuna kukweza ntchito zanu zoyezera magetsi, palibe nthawi yabwino yofufuza kuthekera kwa kuyeza kuchuluka kwa magetsi m'makina.
