Kugwiritsa Ntchito Ma Electromagnetic Flow Meters mu Kuyeza Madzi Owononga

Kuyeza zakumwa zowononga, monga ma acid, alkali, ndi mankhwala osungunulira, kumabweretsa mavuto akulu m'mafakitale chifukwa cha kuwonongeka kwawo ku zipangizo zamagetsi. Ma electromagnetic flow meter (EMFs), kutengera mfundo ya Faraday yogwiritsira ntchito magetsi, apezeka ngati yankho lodalirika pankhaniyi. Kapangidwe kawo koyezera kosasokoneza, kugwirizana ndi mitundu yosiyanasiyana ya zinthu zowononga, komanso kulondola kwakukulu kwa muyeso kumapangitsa kuti zikhale zofunika kwambiri m'mafakitale komwe kuli malo ovuta a mankhwala. Nkhaniyi ikufotokoza ubwino wapadera wa ma EMF pakuyesa madzi owononga, momwe amagwiritsidwira ntchito m'mafakitale ofunikira, komanso mfundo zofunika kwambiri kuti agwire bwino ntchito.

Ubwino waukulu wa ma electromagnetic flow meter poyesa madzi owononga uli mu kapangidwe kake komanso kusinthasintha kwa zinthu. Mosiyana ndi ma flow meter achikhalidwe omwe ali ndi zinthu zosokoneza zomwe zimatha kuwononga, ma EMF ali ndi sensa yokhala ndi lining yomwe imalekanitsa chinthu choyezera kuchokera ku medium yowononga. Zipangizo zodziwika bwino za lining ndi monga PTFE (polytetrafluoroethylene), PFA (perfluoroalkoxy alkane), ndi rabara, zonse zomwe zimawonetsa kukana bwino kwa ma acid, alkalis, ndi organic solvents. Kuphatikiza apo, ma electrode a EMF amatha kupangidwa ndi ma alloys osagwira dzimbiri monga Hastelloy, titanium, kapena tantalum, zomwe zimaonetsetsa kuti zimakhala zokhazikika kwa nthawi yayitali ngakhale m'madzi akumwa amphamvu kwambiri. Njira yoyezera yosakhudzana ndi kukhudzana iyi imachotsanso kutayika kwa kuthamanga ndi chiopsezo chotseka, chomwe ndi chofunikira kwambiri kuti ntchito zamafakitale zipitirire.

Makampani opanga mankhwala ndi omwe amagwiritsidwa ntchito kwambiri pa EMFs poyesa madzi owononga. Mu njira zopangira mankhwala, mitundu yosiyanasiyana ya zinthu zowononga monga sulfuric acid, hydrochloric acid, ndi sodium hydroxide zimafunika kuwongolera bwino kayendedwe ka madzi kuti zitsimikizire kuti zinthu zikuyenda bwino komanso kuti zinthuzo ndi zabwino. Mwachitsanzo, popanga feteleza, ma EMF okhala ndi ma PTFE linings ndi ma Hastelloy electrodes amayesa molondola kuchuluka kwa madzi osungunuka a sulfuric acid, zomwe zimathandiza kuti azitha kugwiritsa ntchito bwino ammonia. Pakupanga mankhwala ophera tizilombo, amawunika momwe zinthu zosungunuka za organic zimayendera, kuonetsetsa kuti njira yochitira zinthu ndi yotetezeka komanso yokhazikika. Kuthekera kwa ma EMF kuyeza madzi owononga motsatira njira yoyendetsera ntchito molondola kwambiri (nthawi zambiri ± 0.5% ya mtengo woyezedwa) kumawapangitsa kukhala gawo lofunikira kwambiri pa njira yodziyimira yokha ya mankhwala.

Makampani opanga migodi ndi zitsulo amadaliranso kwambiri ma EMF poyesa zakumwa zowononga. Mu njira yochotsera zitsulo zopanda chitsulo (monga mkuwa, zinc, ndi golide), zinthu zowononga (monga sulfuric acid solution, cyanide solution) zimagwiritsidwa ntchito kuchotsa zitsulo kuchokera ku miyala. Ma EMF amagwiritsidwa ntchito poyesa kuchuluka kwa madzi otulutsa zitsulozi, kuonetsetsa kuti zikugwirizana ndi miyala ndikuwonjezera mphamvu yochotsera zitsulo. Mu kukonza zitsulo, amawunikanso kuyenda kwa madzi ozizira owononga ndi zinyalala za asidi, zomwe zimathandiza kuchepetsa kugwiritsa ntchito mphamvu ndikukwaniritsa miyezo yotulutsa mphamvu zachilengedwe. Kapangidwe kolimba ka ma EMF kamawathandiza kupirira kutentha kwambiri komanso kuthamanga kwambiri komwe nthawi zambiri kumakumana nako pantchito zamigodi ndi zitsulo.

Malo oyeretsera madzi otayira ndi malo ena ofunikira ogwiritsira ntchito. Madzi otayira m'mafakitale nthawi zambiri amakhala ndi zinthu zowononga monga ma ayoni achitsulo cholemera, ma acid, ndi ma alkali, zomwe zimafuna kuyeza kolondola kwa madzi otayira kuti agwiritsidwe ntchito bwino. Ma EMF amayesa kuchuluka kwa madzi otayira omwe amatayira m'njira zosonkhanitsira ndi kukonza, zomwe zimathandiza kuwongolera bwino zowonjezera za mankhwala (monga ma neutralizers) ndikuwonetsetsa kuti akutsatira malamulo otulutsira madzi. Kukana kwawo ku kuipitsidwa ndi dzimbiri kumatsimikizira kuti ntchito yawo ndi yokhazikika ngakhale m'malo ovuta amadzi otayira, kuchepetsa ndalama zokonzera ndi nthawi yopuma.

Kuti muwonetsetse kuti ma EMF akugwira ntchito bwino poyesa madzi owononga, mfundo zingapo zofunika kuziganizira ziyenera kukumbukiridwa. Choyamba, sankhani zinthu zoyenera zolumikizira ndi ma electrode kutengera mtundu ndi kuchuluka kwa zinthu zowononga. Chachiwiri, onetsetsani kuti madzi oyesedwa ali ndi mphamvu yokwanira yoyendetsera magetsi (nthawi zambiri kuposa 5 μS/cm), chifukwa ma EMF sangayese madzi osayendetsa magetsi. Chachitatu, ikani mita molondola kuti mupewe kusokoneza kwa ma electromagnetic ndikuwonetsetsa kuti pali malo oyenda bwino. Kusamalira nthawi zonse, monga kuwona kukhulupirika kwa ma electrode oyeretsa ndi kukhazikika kwa magetsi, ndikofunikiranso kuti mukhale odalirika kwa nthawi yayitali.

Pomaliza, ma electromagnetic flow mita akhala chisankho chabwino kwambiri poyezera madzi owononga chifukwa cha kusinthasintha kwawo, kulondola kwambiri, komanso magwiridwe antchito okhazikika. Kugwiritsa ntchito kwawo kwakukulu m'makampani opanga mankhwala, migodi, ndi madzi otayira kukuwonetsa gawo lawo lofunikira pakuwonetsetsa kuti njira zikuyenda bwino, mtundu wa malonda, komanso chitetezo cha chilengedwe. Ndi kupita patsogolo kosalekeza muukadaulo wazinthu ndi kapangidwe ka masensa, ma EMF akuyembekezeka kupereka mayankho odalirika kwambiri pazochitika zoyezera zowononga kwambiri mtsogolo.
