Inline density metres ndizomwe zimasinthiratu mayendedwe amagetsi pamafakitale. Ma geji anzeru awa amalola ogwiritsa ntchito kuyang'anira kachulukidwe mu nthawi yeniyeni, komanso zida zofunika kwambiri zothana ndi njira zovuta zamankhwala. Ndikofunikira kuti ogwira ntchito ayang'ane ndi zovuta zogwirira ntchito monga kutsatira malamulo okhwima okhudza chilengedwe. Yang'anani mwatsatanetsatane momwe amathandizira kuthana ndi zovuta zamafakitale ndikuchotsa ntchito yovuta koma yobwerezabwereza.
Zovuta Zaukadaulo Zachinyengo mu Denitration
Kusintha kwa mpweya wa nitrogen oxide (NOx) si ntchito yosavuta. Nayitrojeni okusayidi sakanathetsedwa kotheratu, mosasamala kanthu za zomera zowotchedwa ndi malasha, zowotchedwa ndi mafuta kapenanso zopangira mafuta. Kuwongolera mpweya mwatsatanetsatane kumagwirizana ndi Selective Catalytic Reduction (SCR) kapena Selective Non-Catalytic Reduction (SNCR), momwe ma reagents amawonjezedwa mumtsinje wa gasi kuti achiteponso. Komabe, kuwunika moyenera ma dosing munthawi yeniyeni kumakumana ndi zovuta zambiri kuchokera ku zovuta zogwirira ntchito. Kusalondola muyeso kungayambitse kutsika kwa ammonia ndikuwonongeka kwa ma reagents.
Lonnmeter kupanga ndi kupanga Inline density mitakuti muyezetse ndende mosalekeza kuti mupewe zolakwika za anthu pazotsatira zachikhalidwe. Zitsanzo za anthu zimadalira kwambiri kuwunika kwanthawi ndi nthawi komanso kuyerekezera kosalunjika. ZotereziIntaneti kachulukidwe mitaimatha kuzindikira kusinthasintha kwapang'ono pakuwunika kachulukidwe kuti zithandizire kusintha kolondola, kusunga njira zonse zowonetsera kukhala zokhazikika komanso zogwira mtima.
Kuphatikiza apo, imagwiranso ntchito popereka magawo omwe akuwonetsa kusakanikirana kwamtundu, kusasinthika kwa reagent komanso kuthamanga kwamayendedwe. Mwachitsanzo, kusagwirizana kwa mtsinje wa urea mpaka kusungunuka m'madzi kumasokoneza momwe zimapangidwira. Poyang'anira slurry mwachindunji mu payipi, ma inline kachulukidwe mita amawonetsetsa kuti ndende yomwe mukufuna imasungidwa kuyambira pakusungidwa mpaka jekeseni, kuchepetsa chiwopsezo cha kusakwanira kwa njira kapena kusagwirizana ndi chilengedwe.
Analimbikitsa Industrial Density Meters
Kupititsa patsogolo Automation mu Denitration ndi System Reliability
Anapita kale masiku pamene oyendetsa zomera ankadalira njira zothandizira kukonza bwino jekeseni wa reagent. Mamita amakono a inline density metres amaphatikizana mosadukiza mu advanced Distributed Control Systems (DCS) kapena Programmable Logic Controllers (PLC), kulola kuti pakhale malingaliro odzichitira okha. Pamene kachulukidwe kuwerengera kupatuka pa preset osiyanasiyana, dongosolo basi kusintha reagent otaya mlingo kapena dilutes yankho pakufunika. Zochita zokhazi sizimangochepetsa kulemetsa kwa ogwira ntchito komanso zimachotsa kuchedwa komwe kumakhudzana ndi kupanga zisankho za anthu.
Ndikofunikira kulinganiza mitsinje yamankhwala mu kuphatikiza desulfurization ndi denitration processing, pomwe matope a laimu ndi ammonia amagwiritsidwa ntchito nthawi imodzi. Kuyang'anira kachulukidwe kamadzimadzi awiriwa ndi kofunikira kuti mugwire bwino ntchito ya desulfurization ndi denitration. Kulumikizana kumeneku kumathandiza kupewa zinthu zomwe zimachitika nthawi zambiri monga matope a mapaipi a miyala yamchere kapena kuchulukitsa kwa ammonia, zomwe zingayambitse kuzimitsa kapena kukonza bwino.
Kupatula apo, ma mita olimba olimba otere amalimbana ndi zovuta zamagetsi. Kwa mapangidwe apadera kuti athe kupirira kutentha kwakukulu ndi kukakamizidwa, ndi abwino kugwiritsira ntchito mankhwala owononga nthawi zovuta monga gasi wa flue denitration system.
Kugwiritsa Ntchito Ma Inline Density Meters mu Plant Power Fired
Nthawi zambiri, malo opangira magetsi opangira malasha akuvutitsidwa ndi kusakwanira pakuyezera kachulukidwe ndi zovuta zokhudzana ndiukadaulo motsatizana, kuphatikiza, koma osati kutsekeka kwa mapaipi, kutsika kwa ammonia ndi kukonza komwe kungatheke. The foloko inline density mita ndiye chida chanzeru chanzeru ku mzere wa jakisoni wa ammonia komanso dongosolo la miyala yamchere yamchere.
Zotsatira zake zinali zosintha. Kuyang'anira kachulukidwe munthawi yeniyeni kudapangitsa kuti chomeracho chiwongolere bwino dosing ya reagent molondola kwambiri kuposa kale. Mapiritsi a ammonia adatsika ndi 90%, pomwe kuchepa kwa NOx kudaposa 92%. Dothi la miyala yamchere, lomwe lidayambitsa kale makulitsidwe ndi kutsekeka, lidasungidwa pakuchulukira koyenera, kuthetsa kusamalidwa kosakonzekera ndikuchepetsa nthawi yochepera ndi 20%. Kusintha kumeneku sikunangopangitsa kuti chomeracho chizitsatira miyezo ya chilengedwe komanso kuchepetsa ndalama zogwirira ntchito ndi 15%.
Chifukwa chiyani ma Inline Density Meters Ndiwofunikira
Chomwe chimasiyanitsa ma inline density metres ndi njira zina zowunikira ndikusinthasintha kwawo. Iwo sali kokha kutsutsa; ntchito zawo zimafikira kunjira iliyonse yamafakitale yomwe ikufuna kuwongolera bwino kwamadzimadzi. M'mafakitale opangira magetsi, izi zikuphatikiza njira zochotsera sulfurization, kuthira madzi oyipa, ndi ntchito zophatikiza mafuta. Kukhoza kwawo kupereka zenizeni zenizeni, zolondola, komanso zomwe zingachitike kumawapangitsa kukhala mwala wapangodya wa kukhathamiritsa kwamakono.
Pogwiritsa ntchito zidazi, zopangira magetsi zimatha kukwaniritsa njira yoyendetsera ntchito zomwe poyamba sizinkatheka. Zopindulitsa zimapitilira kutsata komanso kuchita bwino; zikuphatikizanso kupititsa patsogolo moyo wautali wa zida, kuchepetsa mtengo wokonza, komanso kupititsa patsogolo kukhazikika. Kwa ogwira ntchito omwe amayamikira ntchito ndi udindo wa chilengedwe, ma inline density meters si ndalama chabe - ndi zofunika.
Mapeto
Kukhazikitsidwa kwa ma inline density metres m'makina a denitration kumapereka chitsanzo cha momwe ukadaulo wapamwamba ungasinthire njira zamafakitale. Pothana ndi zovuta monga kusasinthasintha kwa reagent, kutsika kwa ammonia, ndikusintha makina, zida izi zimathandiza kuti magetsi azigwira ntchito moyenera, mokhazikika, komanso mopindulitsa. Mbiri yawo yotsimikizika pamapulogalamu adziko lapansi imatsimikizira kufunika kwawo ngati chida chofunikira polimbana ndi mpweya wa NOx. Ngati mukufuna kukweza magwiridwe antchito anu, palibe nthawi yabwinoko yowonera kuthekera kwa kuyeza kachulukidwe wapaintaneti.
