SUP-LDG Magnetic Flowmeter: Ntchito Yonse mu Ntchito Yochiza Madzi ku Philippine

Dzilowetseni mozama mu dzikozaelectromagneticma flowmeters(mag metres) kudzera mu mbiri yopambana padziko lonse lapansi ku Philippines. Bukuli likuwunikira njira yayikulu yoyeretsera madzi ku Metro Manila, ndikuwunikira momweSinoanalyzerMndandanda wa SUP-LDG wa 'SUP-LDG, kuphatikiza mitundu yodziwika bwino komanso yaukhondo, imapereka miyeso yolondola, yodalirika yoyenda m'malo ovuta.

Muphunzira mbiri ya polojekitiyi pakati pa dzikolomadzi oipazovuta, mfundo yoyendetsera mita yozikidwa pa lamulo la Faraday, zinthu zofunika kwambiri monga kulondola kwapamwamba komanso kapangidwe kaukhondo, komanso kugwiritsa ntchito zinthu zosiyanasiyana kuchokera ku zinyalala zosaphika mpaka pokonza zakudya.

Kukumbukira Ntchito Yoyeretsa Madzi ku Philippines

M'matauni a Metro Manila, komwe anthu opitilira 13 miliyoni amakumana ndi kupsinjika kwamadzi pakati pakukula kwachuma komanso mvula yamkuntho pafupipafupi, kuyang'anira madzi oyipa ndi njira yofunikira kwambiri yopulumutsira. Dziko la Philippines likukumana ndi kuipitsa kwakukulu kochokera ku zinyalala zosagwiritsidwa ntchito; 10% yokha yamadzi onyansa am'nyumba amalandila kukonzedwa, kutulutsa matani opitilira 1,000zabiochemicalkufunikira kwa oxygen(BOD) tsiku lililonse m'madzi ofunikira monga mtsinje wa Pasig, malinga ndi kafukufuku wa Dipatimenti ya Zachilengedwe ndi Zachilengedwe (DENR).

Kusintha kwa nyengo, kuphatikizapo chilala cha El Niño ndi mvula yamkuntho ya 20 + pachaka, kumasokoneza mayendedwe operekera, pamene Clean Water Act ya 2004 imalimbikitsa malire a Class C effluent (BOD <50 mg / L) kuteteza zachilengedwe. Malo owopsa a malita 50 miliyoni patsiku (MLD) ku Pasay City, mothandizidwa ndi Maynilad Water Services ndi $ 145 miliyoni kuchokera ku Asia Development Bank (ADB) ndi Japan International Cooperation Agency (JICA), amalimbana ndi ziwopsezozi kudzera mu chithandizo chamankhwala chapamwamba komanso kukonzanso ngalande.

Kukula kumeneku kwa pulogalamu ya NEW WATER, yomwe ikuyang'ana kugwiritsiranso ntchito kwa 12 MLD pofika kumapeto kwa 2025, ikulimbana ndi kusiyana kwakukulu kuchokera kumtsinje wa m'tawuni ndi kutulutsa kosavomerezeka, kuphatikizapo kuchotsa zakudya kuti zigwirizane ndi Miyezo ya Dziko la Philippine National Drinking Water (PNSDW). Chofunika kwambiri pakuchita bwino kwake ndikuwunika kolondola kwa aeration ndi dosing, komweSinomeasure ndiChithunzi cha SUP-LDGmaginitoflowmeteramatumizatekinoloje yosagwiritsa ntchito magetsi yamagetsi yozikidwa m'malamulo a Faraday kuti igwire mitsinje yodzaza zinyalala ndikulondola kwa ± 0.5%, kuchepetsa kugwiritsa ntchito mphamvu ndi 20% ndikupangitsa kukhathamiritsa koyendetsedwa ndi SCADA. Izi sizimangogwirizana ndi kukonzanso kwa Manila Bay koma zimathandizira kukonzanso kwaukhondo paulimi, kulimbikitsa njira yozungulira pakati pa zomwe akuti chithandizo cha 2030 chikuyembekezeka kuwirikiza kawiri.

Kutengera gawo lakutsogolo pakutsata kwamphamvu, SUP-LDG Sanitary Electromagnetic Flowmeter (SUP-LDGS) imatuluka ngati mnzake waukhondo, kuwonetsetsa kuti madzi otayira amasinthidwa mosatekeseka pokonza chakudya ndikuyenda kwamankhwala mosasunthika komanso mosasunthika.

Kuyenda Kupyolera mu Electromagnetic Flow Meter

Zopangidwira zamadzimadzi zomwe zimapangidwira m'malo aukhondo, flowmeter iyi imagwiritsa ntchito mfundo yofananira ndi ma elekitiromagineti popanga voteji kuchokera ku liwiro lamadzimadzi mu gawo la maginito kuti ipereke miyeso ya volumetric yopanda zingwe zosuntha, kuchepetsa kumeta ubweya ndi kuipitsidwa ndi ntchito zovutirapo.

Mogwirizana ndi EHEDG ndi 3-A mfundo, ndi SUP-LDGS zimaonetsa electropolished 316L zosapanga dzimbiri zitsulo wetted njira ndi mng'oma wopanda mng'oma mitsinje pambuyo mankhwala mu malo Philippines kumene mankhwala ophera tizilombo madzi amadyetsa chakumwa dilution kapena mkaka kuzirala mizere.

Ndi miyeso ya DN15-DN1000 ndi ma velocities kuchokera ku 0.2-15 m / s, imakhala ndi madzi otsitsimula otsika (≥5 μS / cm kwa zosakanizidwa zamadzimadzi) popanda madontho apansi, kuthandizira CIP / SIP kuzungulira mpaka 180 ° C muzosintha zogawanika. Zotulutsa ngati 4-20 mA, pulse, ndi RS485/Modbus zimaphatikizana molimbika ndi SCADA yomwe ilipo, kupereka zowunikira zenizeni kuti zipewe kuyimilira m'malo olimbikitsira.

M'malo mwake, SUP-LDGS imagwirizanitsa magwero a madzi oipa kuti agwiritsenso ntchito mowonjezera phindu, kuphatikizira kudzipereka kwa Sinomeasure pazida zolimba, zosinthika zomwe zimagwirizana ndi ukhondo wapadziko lonse lapansi ndikuthana ndi zovuta zakumaloko monga kusefukira kwamphamvu kwamvula.

Kuzama mu luso lake la uinjiniya, SUP-LDGS ili ndi mndandanda wazinthu zomwe zimatsimikizira kudalirika pakukhazikitsa kwaukhondo, monga zafotokozedwera muzolemba zaukadaulo za Sinomeasure. Kulondola kumafika pa ± 0.5% ya mtengo (kapena ± 2 mm / s pa <1 m / s), ndi 0.2% kubwereza kwa kusamutsa m'manja, kuwonetsetsa kutsatiridwa muzogulitsa zakudya kunja. Zida za liner-PFA, F46, PTFE, FEP, kapena neoprene-zimapereka kukana kwa dzimbiri kwa pH 0-14 media, pomwe zosankha za electrode (Hastelloy C-276, titanium, tantalum, kapena platinamu-iridium) zimapirira zotsukira zowuma popanda kutsika.

Kulekerera kutentha kwamadzi kumayambira -20 ° C mpaka 160 ° C, ndi ntchito yozungulira kuchokera -20 ° C mpaka 60 ° C ndi IP65 / IP67 chitetezo ku fumbi ndi kumizidwa. Zofunikira zamagetsi ndizochepa (AC 85-265V kapena DC 24V), kujambula <0.65W, ndipo kusinthasintha kwa unsembe kumaphatikizapo flange (DIN/JIS/ANSI), clamp, kapena zokwera ulusi, zokhala ndi zingwe zolumikizira mpaka 11mm. Mitundu yotsimikizira kuphulika (ExiaIICT6 Gb) imagwirizana ndi madera osasunthika, ndipo mawonekedwe a mita amalola ma transmitter akutali mtunda wa 50m, kumathandizira kukonza nyengo yachinyontho ku Philippines. Izi, zotsimikiziridwa ndi miyezo ya JB/T 9248-2015, zimatsimikizira zaka 10 za moyo wa ma elekitirodi, njira zina zamakina zochulukira kwambiri zomwe zimatha kuvala mu ma viscous slurries ngati kuchira kwamkati.

Zinthu zazikuluzikulu zimakwezanso SUP-LDGS ngati mphamvu yocheperako yowongolera bwino kuyenda. Kukokera kwake kwapawiri-kawirikawiri kumalimbitsa ma siginecha mumikhalidwe yogunda kapena yotsika, kuchotsa phokoso kuchokera ku thovu kapena zolimba zomwe zimafala pakupukuta kwaukhondo, pomwe liner yosayendetsa imalepheretsa kuchulukana, kukulitsa nthawi yautumiki.

Kuzindikira kwa mapaipi opanda kanthu pogwiritsa ntchito njira zapamwamba kumayimitsa kuwerengera zabodza, ndi ntchito zodziwunikira, zopezeka kudzera pa HART protocol, zokutira mbendera zamagetsi kapena kuphwanya kwa liner koyambirira, kuchepetsa nthawi yosakonzekera mpaka 30%. Pakuchita bwino kwaukhondo, zolumikizira mwachangu zolumikizira katatu zimalola kuti zida zopanda zida zitsimikizidwe, kuchepetsa nthawi yokonzekera yowerengera, komanso kusakhalapo kwa madera akufa kumathandizira kutsimikizira kopanda upangiri wa GMP.

Poyerekeza ndi akupanga mamita, kusakhudzidwa kwake ndi kusiyana kwa kachulukidwenthawipHzosinthaZimapereka kuwongolera kolimba, kukulitsa zokolola ndi 5-10% pakuphatikiza ntchito. Makhalidwe amenewa, ophatikizidwa ndi kuthekera koyenda kwa mbali ziwiri pakukankhira m'mbuyo, kumapangitsa SUP-LDGS kukhala mita imodzi yokha koma kukhala chinthu chothandizira pakuwonetsetsa kuti madzi akumwa akuyenda bwino kuchokera m'mapaipi a Metro Manila kupita ku mapaipi aukhondo otsika.

SUP-LDGS imapeza ntchito zosunthika m'mafakitale onse pomwe ukhondo umakhala wofunikira, makamaka muzachilengedwe za polojekiti ya ku Philippines. M'zakudya ndi zakumwa, imayang'anira zowonjezera zowonjezera monga madzi mu dilution ya madzi kapena kuziziritsa kwapasteurization, kusunga kusasinthasintha kwa batch pakati pa ma viscosity osiyanasiyana mpaka 1000 cP.

Mizere yamankhwala imapindula ndi kutsatiridwa kwake pakugawa madzi oyeretsedwa kapena granulation ya piritsi, kukweza zipika zovomerezeka ndi FDA kuti zitsimikizire zotumiza kunja. Kupitilira pakupanga mkaka kumapangitsa kuti mkaka ukhale wokhazikika, pomwe opangira mowa amatsata wort amayenda m'matangi owiritsa, onse amatsatira ukhondo wa 3-A.

M'malo amadzi onyansa ngati malowa a Manila, amayang'anira mitsinje yobwezeretsedwa ya ulimi wothirira, kuletsa kuthirira kopitilira muyeso komwe kumawonjezera mchere m'minda ya mpunga.

Mankhwala m'magawo ntchito kwa neutralized effluents mu mtanda reactors, ndi zodzoladzola kwa emulsion kusanganikirana, kumene yeniyeni metering curtails zinyalala. Ndi scalability kuchokera ku lab-scale DN15 kupita ku DN1000 ya mafakitale, komanso kukakamiza ku 1.6-4.0 MPa, imathandizira zoyeserera zotulutsa madzi a zero m'magawo oyandikana ndi migodi ngati Cebu, kubwezeretsanso ma brines opanda ziwopsezo zazing'ono. Pamapeto pake, kugwiritsa ntchito izi kumasintha madzi oyeretsedwa kuchoka ku katundu kupita ku phindu, kuyendetsa bwino m'madera omwe mulibe madzi.
