Umgaqo wokusebenza kunye neentlobo ze-aerators

Iimpawu eziphambili zentsebenzo ye-aerator zichazwa njengomthamo we-aerobic kunye nokusebenza kakuhle kwamandla.Umthamo we-oxygenation ubhekisela kwisixa se-oksijini esongezwa kumzimba wamanzi nge-aerator ngeyure, kwiikhilogram / ngeyure;ukusebenza kakuhle kwamandla kubhekiselele kwisixa se-oksijini yamanzi athi i-aerator isebenzise i-1 kWh yombane, ngeekhilogram/kWh.Ngokomzekelo, i-aerator ye-1.5 kW yamanzi inamandla okusebenza kwe-1.7 kg / kWh, oku kuthetha ukuba umatshini usebenzisa i-1 kWh yombane kwaye unokongeza i-1.7 kg ye-oksijini kumzimba wamanzi.
Nangona ii-aera zisetyenziswa kakhulu kwimveliso yasemanzini, abanye abenzi bokuloba abakawuqondi umthetho-siseko wayo wokusebenza, uhlobo kunye nomsebenzi, kwaye ababoni kwaye baziimpazamo ekusebenzeni kwayo.Apha kuyimfuneko ukuqonda umgaqo wayo wokusebenza kuqala, ukwenzela ukuba iya kuba yinkosi ekusebenzeni.Njengoko sonke siyazi, injongo yokusebenzisa i-aerator kukongeza i-oksijini enyibilikisiweyo emanzini, okubandakanya ukunyibilika kunye nesantya sokuchithwa kwe-oksijini.Ukunyibilika kubandakanya izinto ezintathu: ubushushu bamanzi, umxholo wetyuwa yamanzi, kunye noxinzelelo oluyinxenye yeoksijini;izinga lokuchithwa libandakanya izinto ezintathu: iqondo lokungahlambuluki kwe-oksijeni echithiweyo, indawo yoqhagamshelwano kunye nendlela yegesi yamanzi, kunye nokuhamba kwamanzi.Phakathi kwabo, ubushushu bamanzi kunye ne-salinity yamanzi yimeko ezinzile yomzimba wamanzi, ongenakuguqulwa ngokubanzi.Ngoko ke, ukuze ufezekise ukongezwa kweoksijini kumzimba wamanzi, izinto ezintathu kufuneka zitshintshwe ngokuthe ngqo okanye ngokungathanga ngqo: uxinzelelo lwe-oksijini, indawo yoqhagamshelwano kunye nendlela yamanzi kunye negesi, kunye nokuhamba kwamanzi.Ukuphendula kule meko, amanyathelo athathiweyo xa kuyilwa i-aerator ngala:
I-1) Sebenzisa iindawo zomatshini ukuvuselela umzimba wamanzi ukukhuthaza utshintshiselwano lwe-convective kunye nokuhlaziywa kwe-interface;
2) Ukusasaza amanzi kumathontsi enkungu entle kwaye uwatshize kwisigaba segesi ukonyusa indawo yokunxibelelana yamanzi kunye negesi;
3) Ukuphefumla ngoxinzelelo olubi ukusabalalisa igesi kwi-micro-bubbles kwaye ucinezele emanzini.
Iindidi ezahlukeneyo ze-aerator ziyilwe kwaye zenziwe ngokwale migaqo, kwaye zithatha umlinganiselo omnye ukukhuthaza ukuchithwa kwe-oksijini, okanye zithathe amanyathelo amabini okanye ngaphezulu.
I-aerator ye-impeller
Inemisebenzi ebanzi efana nokuphefumla, ukunyakaziswa kwamanzi, kunye nogqabhuko-dubulo lwerhasi.Yeyona isetyenziswayo ngoku, enexabiso lemveliso yonyaka malunga neeyunithi ezingama-150,000.Umthamo wayo we-oxygen kunye nokusebenza kakuhle kwamandla kungcono kunezinye iimodeli, kodwa ingxolo yokusebenza inkulu.Isetyenziselwa i-aquaculture kumachibi ommandla omkhulu kunye nobunzulu bamanzi obungaphezu kwe-1 mitha.

I-aerator yamavili:Inefuthe elihle lokunyusa i-oxygen kunye nokukhuthaza ukuhamba kwamanzi, kwaye ifanelekile kumachibi anentlenga enzulu kunye nommandla we-1000-2540 m2 [6].
I-aerator yeJet:Amandla ayo okusebenza ngamandla okuphefumla angaphezulu kohlobo lwamavili amanzi, uhlobo olunomoya, uhlobo lwesitshizi samanzi kunye nezinye iindlela ze-aerators, kwaye ubume bayo bulula, obunokwenza ukuhamba kwamanzi kunye nokushukumisa umzimba wamanzi.Umsebenzi we-jet oxygenation unokwenza umzimba wamanzi u-oksijeni uhambe kakuhle ngaphandle kokulimaza umzimba weentlanzi, olungele ukusetyenziswa kwe-oxygenation kumachibi e-fry.
Iaerator yesitshizi samanzi:Inomsebenzi omhle wokuphucula i-oksijeni, inokunyusa ngokukhawuleza i-oksijini echithwe kumanzi angaphezulu ngexesha elifutshane, kwaye ibuye ibe nefuthe lobugcisa bomhlobiso, olufanelekileyo kumachibi eentlanzi kwiigadi okanye kwiindawo zokutyelela.
I-aerator evuthelwayo:Amanzi anzulu, ngcono umphumo, kwaye ifanelekile ukusetyenziswa kumanzi anzulu.
Ukuphefumla umoya:Umoya uthunyelwa emanzini ngokufunxa uxinzelelo olubi, kwaye yenza i-vortex ngamanzi ukutyhala amanzi phambili, ngoko ke amandla okuxuba anamandla.Amandla ayo okuphucula ioksijini kumanzi asezantsi anamandla kune-impeller aerator, kwaye amandla ayo okuphucula i-oxygen kumanzi angaphezulu angaphantsi kancinane kune-impeller aerator [4].
Eddy flow aerator:Isetyenziselwa ikakhulu i-oksijini yamanzi angaphantsi komkhenkce kumantla eTshayina, kunye nokusebenza kakuhle kwe-oxygen [4].
Impompo yeoksijini:Ngenxa yobunzima bayo obulula, ukusebenza ngokulula kunye nomsebenzi omnye wokuphucula ioksijini, ifanelekile ngokubanzi kumachibi okulima i-fry okanye amachibi okulima i-greenhouse enobunzulu bamanzi obungaphantsi kwe-0.7 yeemitha kunye nommandla ongaphantsi kwe-0.6 mu.
