Isimiso sokusebenza nezinhlobo zama-aera

Izinkomba zokusebenza eziyinhloko ze-aerator zichazwa njengomthamo we-aerobic kanye nokusebenza kahle kwamandla.Umthamo womoya-mpilo ubhekisela enanini lomoya-mpilo owengezwe emanzini nge-aerator ngehora, ngamakhilogremu/ihora;ukusebenza kahle kwamandla kubhekisela enanini le-oxygenation lamanzi i-aerator edla i-1 kWh kagesi, ngamakhilogremu/kWh.Isibonelo, i-aerator yesondo lamanzi engu-1.5 kW inamandla okusebenza kahle angu-1.7 kg/kWh, okusho ukuthi umshini udla u-1 kWh kagesi futhi ungangeza u-1.7 kg womoya-mpilo emanzini.
Nakuba ama-aerator esetshenziswa kabanzi ekukhiqizeni izilwane zasemanzini, abanye abasebenzi bemboni yokudoba abakaqondi isimiso sayo sokusebenza, uhlobo kanye nomsebenzi wayo, futhi ababoni futhi benza nje ngokungahleliwe ekusebenzeni kwangempela.Lapha kuyadingeka ukuqonda isimiso sayo sokusebenza kuqala, ukuze sizokwazi ukusebenza kahle.Njengoba sonke sazi, inhloso yokusebenzisa i-aerator iwukwengeza i-oxygen encibilikile emanzini, okubandakanya izinga lokuncibilika nelokuhlakazeka komoyampilo.Ukuncibilika kuhlanganisa izici ezintathu: izinga lokushisa lamanzi, okuqukethwe kukasawoti wamanzi, nokucindezela ingxenye komoyampilo;izinga lokuncibilika lihlanganisa izici ezintathu: izinga lokungagcwali kwe-oksijini encibilikile, indawo yokuthintana nendlela yegesi-manzi, kanye nokuhamba kwamanzi.Phakathi kwazo, izinga lokushisa lamanzi kanye nosawoti wamanzi yisimo esizinzile somzimba wamanzi, esingenakushintshwa ngokujwayelekile.Ngakho-ke, ukuze kuzuzwe ukungezwa kwe-oksijeni emzimbeni wamanzi, izici ezintathu kufanele zishintshwe ngokuqondile noma ngokungaqondile: ukucindezela okuyingxenye ye-oksijeni, indawo yokuxhumana kanye nendlela yamanzi negesi, nokuhamba kwamanzi.Ukuphendula lesi simo, izinyathelo ezithathwa lapho kuklanywa i-aerator yilezi:
1) Sebenzisa izingxenye zemishini ukunyakazisa umzimba wamanzi ukukhuthaza ukushintshaniswa kwe-convective kanye nokuvuselelwa kwesixhumi esibonakalayo;
2) Hlakaza amanzi abe amaconsi enkungu amahle bese uwafafaza esigabeni segesi ukuze ukwandise indawo yokuxhumana yamanzi negesi;
3) Hofuza ngengcindezi engemihle ukuze uhlakaze igesi ibe amabhamuza amancane bese ucindezela emanzini.
Izinhlobo ezahlukene zama-aerator ziklanywa futhi zenziwa ngokwalezi zimiso, futhi zithatha isilinganiso esisodwa ukuze zikhuthaze ukuqedwa komoya-mpilo, noma zithathe izinyathelo ezimbili noma ngaphezulu.
I-aerator ye-impeller
Inemisebenzi ebanzi efana nokufaka umoya, ukunyakazisa amanzi, nokuqhuma kwegesi.Iyona esetshenziswa kakhulu i-aerator njengamanje, enevelu yokukhipha yonyaka engaba amayunithi ayi-150,000.Umthamo wayo we-oxygenation nokusebenza kahle kwamandla kungcono kunamanye amamodeli, kodwa umsindo wokusebenza mkhulu kakhulu.Isetshenziselwa i-aquaculture emachibini amakhulu anendawo yokujula kwamanzi angaphezu kwemitha eyi-1.

I-aerator ye-Waterwheel:Inomphumela omuhle wokwandisa umoya-mpilo nokukhuthaza ukugeleza kwamanzi, futhi ifanele amachibi anodaka olujulile nendawo engu-1000-2540 m2 [6].
I-aerator ye-Jet:Amandla ayo okukhipha umoya adlula lawo ohlobo lwesondo lamanzi, uhlobo oluphefumulayo, uhlobo lwesifutho samanzi nezinye izinhlobo zama-aera, futhi ukwakheka kwayo kulula, okungakha ukugeleza kwamanzi nokunyakazisa umzimba wamanzi.Umsebenzi we-jet oxygenation ungenza umzimba wamanzi uphefumule kahle ngaphandle kokulimaza umzimba wezinhlanzi, ofanele ukusetshenziswa kwe-oxygenation emachibini okuthosa.
I-aerator yesifutho samanzi:Inomsebenzi omuhle wokuthuthukisa umoya-mpilo, ingakhuphula ngokushesha umoya-mpilo oncibilikisiwe emanzini angaphezulu ngesikhathi esifushane, futhi iphinde ibe nomphumela wokuhlobisa wobuciko, ofanele amachibi ezinhlanzi ezingadini noma ezindaweni zokuvakasha.
I-aerator ene-inflatable:Lapho amanzi ejula, umphumela uba ngcono, futhi ulungele ukusetshenziswa emanzini ajulile.
I-aerator yokuphefumula:Umoya uthunyelwa emanzini ngokumunca umfutho ongemuhle, futhi wenza i-vortex namanzi ukusunduza amanzi phambili, ngakho amandla okuhlanganisa anamandla.Ikhono layo lokuthuthukisa umoya-mpilo emanzini aphansi linamandla kunalelo le-impeller aerator, futhi ikhono layo lokuthuthukisa umoya-mpilo emanzini angaphezulu lingaphansi kancane kunalelo le-impeller aerator [4].
I-Eddy flow aerator:Isetshenziselwa kakhulu umoya-mpilo wamanzi angaphansi kweqhwa enyakatho yeChina, ngokusebenza kahle kwe-oxygenation ephezulu [4].
Iphampu ye-oxygen:Ngenxa yesisindo sayo esilula, ukusebenza okulula kanye nomsebenzi owodwa wokuthuthukisa umoya-mpilo, ngokuvamile ilungele amachibi okulima okuthosiwe noma amachibi okulima okubamba ukushisa anobunzulu bamanzi obungaphansi kwamamitha angu-0.7 nendawo engaphansi kuka-0.6 mu.
