1. Intshayelelo
1.1 Imvelaphi
Ukukhutshwa kwamanzi amdaka kwimizi-mveliso kuzisa umngcipheko omkhulu kwiinkqubo zendalo nakwimpilo yoluntu. Ukubeka iliso kwindlela esebenza ngayo ngexesha langempela kubalulekile ekuphuculeni iinkqubo zonyango nokuqinisekisa ukuthotyelwa kwemigaqo yokusingqongileyo, njengoko idatha engachanekanga yokuphuma kwamanzi ingakhokelela ekusetyenzisweni kweekhemikhali ngendlela engasebenzi kakuhle okanye ekungcoleni kwamanzi amdaka angaphantsi komgangatho.
1.2 Injongo yolu phononongo
Eli phepha lihlola ukusetyenziswa kwee-electromagnetic flowmeters (ii-EMF) kunyango lwamanzi amdaka kwimizi-mveliso, lijolise ekuqaqambiseni indima yazo ekuphuculeni ukusebenza kakuhle kwenkqubo kunye nokukhuselwa kokusingqongileyo.
2. Umgaqo Wokusebenza weIi-flowmeters ze-electromagnetic
2.1 Umthetho kaFaraday wokungenisa i-Electromagnetic
Ii-EMF zisebenza ngokomthetho kaFaraday: xa amanzi amdaka ahamba ngemagnethi, avelisa amandla e-electromotive abangelwa yi-induced (EMF) alingana nesantya sokuhamba. Le EMF ifunyanwa zii-electrodes, kwaye izinga lokuhamba libalwa ngokucubungula isignali.
2.2 Iimpawu zobugcisa
Iimpawu eziphambili ziquka uyilo olungangenisi manzi (akukho kuphazamiseka kokuhamba kwamanzi), ukuchaneka okuphezulu (± 0.5% yesikali esipheleleyo), uluhlu olubanzi (1:100 turndown ratio), kunye nokumelana nokugqwala okuvela kumanzi amdaka ane-asidi/alkaline.
3. Imizekelo yokusetyenziswa kunyango lwamanzi amdaka kwimizi-mveliso
3.1 Ukubeka esweni ukuhamba kwamanzi okungena
Ii-EMF zilandelela amazinga okungena kwamanzi ukuthintela ukugcwala kakhulu kweetanki zonyango, ziqinisekisa ukusebenza rhoqo kweeyunithi zokutsalwa kwenkunkuma kunye nezonyango lwebhayoloji.
3.2 Ulawulo lokuDosa iiKhemikhali
Zidibene neenkqubo ze-PLC, ii-EMF zilungisa idosi ye-coagulant/flocculant ngokusekelwe ekuhambeni kwexesha langempela, zinciphisa inkunkuma yeekhemikhali nge-15-20% xa kuthelekiswa nedosi emiselweyo.
3.3 Ukubeka esweni ukuhamba kodaka
Zilinganisa ukubuya kodaka kunye nokuhamba kokulahla, ziphucula ukusebenza kakuhle kokugaya ukutya okungena-aerobic kwaye zinciphisa iindleko zokuphatha udaka olugqithisileyo.
4. Ukuhlanganiswa kweNkqubo kunye noLawulo lweDatha
4.1 Uqwalaselo lweHardware
Ii-EMF zidityaniswa neetransmitters, ii-pH sensors, kunye neenkqubo ze-DCS. Zigxila kwizinto ze-electrode (umz., i-Hastelloy yolwelo oluqinileyo) kunye nokuhambelana kobukhulu bepayipi.
4.2 Ulawulo lweSoftware kunye noHlalutyo lweDatha
Isoftware esisiseko ivumela ukubonakala kokuhamba kwexesha langempela kunye nokuvuselela i-alamu kumanqanaba angaqhelekanga. Ukugcina idatha ngokulula kuxhasa uphononongo lokusebenza kwenkqubo rhoqo ngeveki.
5. Iingenelo kunye nokubaluleka
5.1 Iingenelo zobuGcisa
Ngokungafaniyo nee-turbine flowmeters,Ii-EMFazichaphazeleki yi-fluid viscosity okanye izinto eziqinileyo ezixhonyiweyo, nto leyo enciphisa ukugcinwa kwazo rhoqo.
5.2 Iingenelo zeNdalo nezoQoqosho
Ziqinisekisa ukuba ukungcola kuyahlangabezana nemida yokukhupha, ziphepha izigwebo. Ngokusebenzisa kakuhle iikhemikhali kunye nokusetyenziswa kwamandla, iindleko zokusebenza zincitshiswa nge-10-15%.
6. Imingeni kunye nophuhliso lwexesha elizayo
6.1 Imingeni ekhoyo
Ukungcola kwee-electrode ngezinto eziphilayo kufuna ukucocwa rhoqo. Iindleko eziphezulu zokufakela zinokuthintela izakhiwo ezincinci.
6.2 Iindlela Eziza Kulandela
Ukuhlanganiswa ne-IoT kuya kwenza kube lula ukujonga kude kunye nokugcinwa kwangaphambili. Ukuphuhliswa kwee-EMF ezingabizi kakhulu nezincinci kuya kwandisa ukusetyenziswa kwazo.
7. Isiphelo
Ii-EMF zibalulekile ekubekweni esweni ngexesha langempela kunyango lwamanzi amdaka kwimizi-mveliso, zibonelela ngeenzuzo zobugcisa, zokusingqongileyo, kunye nezoqoqosho. Ukujongana nemingeni ekhoyo kunye nokwamkela ubuchwepheshe obukrelekrele kuya kuyiphucula ngakumbi indima yabo kulawulo lwamanzi oluzinzileyo.
