Mfundo yogwirira ntchito ndi mitundu ya ma aerators

Zizindikiro zazikulu za ntchito ya aerator zimatanthauzidwa ngati mphamvu ya aerobic ndi mphamvu zamagetsi.Mphamvu ya okosijeni imatanthawuza kuchuluka kwa okosijeni wowonjezeredwa m'thupi lamadzi ndi mpweya pa ola, mu kilogalamu / ola;mphamvu yamphamvu imatanthawuza kuchuluka kwa okosijeni kwa madzi omwe mpweya umawononga 1 kWh yamagetsi, mu kilogalamu/kWh.Mwachitsanzo, 1.5 kW waterwheel aerator imakhala ndi mphamvu ya 1.7 kg / kWh, zomwe zikutanthauza kuti makina amawononga 1 kWh yamagetsi ndipo amatha kuwonjezera 1.7 kg ya okosijeni kumadzi.
Ngakhale ma aerator amagwiritsidwa ntchito kwambiri popanga ulimi wa m'madzi, asodzi ena samamvetsetsabe mfundo zake zogwirira ntchito, mtundu wake ndi momwe zimagwirira ntchito, ndipo ndi akhungu komanso mwachisawawa pakugwira ntchito kwake.Apa m'pofunika kumvetsetsa mfundo yake yogwirira ntchito poyamba, kuti ikhale yodziwika bwino.Monga tonse tikudziwira, cholinga chogwiritsira ntchito mpweya ndi kuwonjezera mpweya wosungunuka m'madzi, zomwe zimaphatikizapo kusungunuka ndi kusungunuka kwa mpweya.Kusungunuka kumaphatikizapo zinthu zitatu: kutentha kwa madzi, mchere wamadzi, ndi mpweya wochepa wa mpweya;Kusungunuka kumaphatikizapo zinthu zitatu: mlingo wa unsaturation wa mpweya wosungunuka, malo okhudzidwa ndi njira ya madzi-gasi, ndi kayendedwe ka madzi.Pakati pawo, kutentha kwa madzi ndi mchere wamadzi m'madzi ndi chikhalidwe chokhazikika chamadzi, chomwe sichingasinthidwe kawirikawiri.Choncho, kuti tikwaniritse kuwonjezera kwa okosijeni m'madzi, zinthu zitatu ziyenera kusinthidwa mwachindunji kapena mosadziwika bwino: kupanikizika pang'ono kwa mpweya, malo okhudzidwa ndi njira ya madzi ndi gasi, ndi kayendedwe ka madzi.Poyankha izi, njira zomwe zimatengedwa popanga aerator ndi:
1) Gwiritsani ntchito zida zamakina kusonkhezera thupi lamadzi kulimbikitsa kusinthana kwa convective ndi kukonzanso mawonekedwe;
2) Kumwaza madzi mu madontho abwino a nkhungu ndikuwapopera mu gawo la mpweya kuti muwonjezere malo okhudzana ndi madzi ndi mpweya;
3) Kukoka mpweya kudzera kukakamiza koyipa kuti mumwaze mpweya kukhala tinthu tating'onoting'ono ndikusindikiza m'madzi.
Mitundu yosiyanasiyana ya ma aerator amapangidwa ndikupangidwa motsatira mfundozi, ndipo amatha kutenga muyeso umodzi kulimbikitsa kusungunuka kwa okosijeni, kapena kutenga miyeso iwiri kapena kupitilira apo.
Impeller aerator
Lili ndi ntchito zambiri monga mpweya, kugwedeza madzi, ndi kuphulika kwa gasi.Ndiwo mpweya wogwiritsidwa ntchito kwambiri pakadali pano, wokhala ndi mtengo wotulutsa pafupifupi mayunitsi 150,000.Mphamvu yake ya okosijeni ndi mphamvu zake zimakhala bwino kuposa zitsanzo zina, koma phokoso la ntchito ndilokulirapo.Amagwiritsidwa ntchito pazakudya zam'madzi m'mayiwe akuluakulu okhala ndi madzi akuya kuposa mita imodzi.

Woyendetsa madzi:Zimakhala ndi zotsatira zabwino zowonjezera mpweya ndi kulimbikitsa kuyenda kwa madzi, ndipo ndi oyenera maiwe omwe ali ndi silt yakuya komanso malo a 1000-2540 m2 [6].
Woyendetsa ndege:Mphamvu yake yamagetsi imaposa mtundu wa magudumu amadzi, mtundu wa inflatable, mtundu wa kupopera madzi ndi mitundu ina ya ma aerators, ndipo mawonekedwe ake ndi osavuta, omwe amatha kupanga madzi oyenda ndikuyambitsa madzi.Ntchito ya jet oxygenation imatha kupangitsa kuti thupi lamadzi likhale ndi oxygen bwino popanda kuwononga thupi la nsomba, lomwe ndi loyenera kugwiritsa ntchito oxygenation m'mayiwe achangu.
Madzi opopera mpweya:Lili ndi ntchito yabwino yowonjezeretsa okosijeni, imatha kuonjezera mpweya wosungunuka m'madzi pamwamba pa nthawi yochepa, komanso imakhala ndi luso lokongoletsera, lomwe liri loyenera kumayiwe a nsomba m'minda kapena malo oyendera alendo.
Mpweya wotentha:Kuzama kwamadzi kumapangitsa zotsatira zake bwino, ndipo ndizoyenera kugwiritsidwa ntchito m'madzi akuya.
Mpweya wopumira:Mpweya umatumizidwa m'madzi kupyolera mu kukakamiza koipa, ndipo umapanga vortex ndi madzi kukankhira madzi patsogolo, kotero mphamvu yosakaniza imakhala yamphamvu.Mphamvu yake yowonjezeretsa mpweya kumadzi apansi ndi yamphamvu kuposa ya mpweya woyendetsa mpweya, ndipo mphamvu yake yowonjezera mpweya kumadzi apamwamba ndi yotsika pang'ono poyerekeza ndi impeller aerator [4].
Eddy flow aerator:Amagwiritsidwa ntchito makamaka kutulutsa mpweya wamadzi apansi panthaka kumpoto kwa China, ndi mpweya wabwino kwambiri [4].
Pampu ya oxygen:Chifukwa cha kulemera kwake, kugwira ntchito kosavuta komanso ntchito imodzi yowonjezeretsa okosijeni, nthawi zambiri ndi yoyenera kumayiwe olima mwachangu kapena maiwe olimapo greenhouses okhala ndi madzi akuya osakwana 0.7 metres ndi malo osakwana 0.6 mu.
