Nheyo yekushanda uye mhando dzeaerators

Iwo makuru ekuita zviratidzo zveaerator anotsanangurwa se aerobic kugona uye kugona kwesimba.Oxygenation capacity inoreva kuwanda kweokisijeni inowedzerwa kumuviri wemvura neaerator paawa, mukirogiramu/awa;kushanda kwemagetsi kunoreva kuwanda kweokisijeni yemvura iyo aerator inoshandisa 1 kWh yemagetsi, mumakirogiramu/kWh.Semuenzaniso, 1.5 kW waterwheel aerator ine simba rekushanda kwe1.7 kg / kWh, zvinoreva kuti muchina unodya 1 kWh yemagetsi uye unogona kuwedzera 1.7 kg yeokisijeni kumvura yemvura.
Kunyange zvazvo maeerators ari kunyanya kushandiswa mukugadzirwa kwemvura, vamwe varairi vehove havasati vanzwisisa misimboti yekushanda kwayo, mhando uye mashandiro ayo, uye ibofu uye zvisina tsarukano mukushanda chaiko.Pano zvakakosha kuti unzwisise nheyo yekushanda kwayo kutanga, kuitira kuti ive nyanzvi mukuita.Sezvatinoziva tose, chinangwa chekushandisa aerator ndechekuwedzera okisijeni yakanyungudika kumvura, iyo inosanganisira kunyungudika uye kuparara kweokisijeni.Solubility inosanganisira zvinhu zvitatu: tembiricha yemvura, munyu wemvura wemukati, uye mweya weokisijeni zvishoma;chiyero chekunyungudika chinosanganisira zvinhu zvitatu: dhigirii rekusaturwa kweokisijeni yakanyungudika, nzvimbo yekusangana uye nzira yemvura-gasi, uye kufamba kwemvura.Pakati pavo, kutonhora kwemvura uye salinity yemvura inenge yakagadzikana yemuviri wemvura, iyo isingagoni kuchinjwa zvachose.Naizvozvo, kuti uwane kuwedzera kweokisijeni kumuviri wemvura, zvinhu zvitatu zvinofanirwa kushandurwa zvakananga kana zvisina kunanga: kumanikidzwa kwechikamu cheokisijeni, nzvimbo yekubata uye nzira yemvura uye gasi, uye kufamba kwemvura.Mukupindura mamiriro ezvinhu aya, matanho anotorwa pakugadzira aerator ndeaya:
1) Shandisa michina nhengo kumutsa muviri wemvura kusimudzira convective exchange uye interface kuvandudzwa;
2) Kuparadzira mvura mumadonhwe akanaka emhute uye woapfapfaidza muchikamu chegasi kuti uwedzere nzvimbo yekubata yemvura uye gasi;
3) Inhale kuburikidza nekumanikidza kwakashata kuparadzira gasi mudiki-mabhuru uye pinda mumvura.
Mhando dzakasiyana-siyana dzemaaera akagadzirwa uye anogadzirwa zvinoenderana nemisimboti iyi, uye anogona kutora chiyero chimwe kukurudzira kuparara kweokisijeni, kana kutora maviri kana anopfuura matanho.
Impeller aerator
Iine mabasa akazara akadai seaeration, kubvongodza mvura, uye kuputika kwegasi.Ndiyo aerator inonyanya kushandiswa pari zvino, ine mutengo wepagore wekubuda ungangoita 150,000 mayunitsi.Iyo oxygenation simba uye kugona kwesimba zviri nani pane mamwe mamodheru, asi ruzha rwekushandisa rwakakura.Inoshandiswa kune aquaculture mumadziva makuru-akadzika ane mvura yakadzika inopfuura 1 mita.

Waterwheel aerator:Iine mhedzisiro yakanaka yekuwedzera oxygenation uye kukurudzira kuyerera kwemvura, uye yakakodzera madziva ane yakadzika silt uye nzvimbo ye1000-2540 m2 [6].
Jet aerator:Simba rayo rekufemesa simba rinopfuura iro remhando yemvura, inflatable type, mvura yekupfapfaidza mhando uye mamwe mafomu eaerator, uye chimiro chayo chiri nyore, chinogona kuumba kuyerera kwemvura uye kubvongodza muviri wemvura.Iyo jet oxygenation basa inogona kuita kuti muviri wemvura oxygenate zvakanaka pasina kukuvadza muviri wehove, iyo yakakodzera kushandiswa kweokisijeni mumadziva efry.
Mvura yekupfapfaidza aerator:Iine basa rakanaka rekusimudzira okisijeni, rinogona kukurumidza kuwedzera iyo yakanyungudika mumvura pamusoro pemvura munguva pfupi, uye zvakare ine hunyanzvi hwekushongedza mhedzisiro, yakakodzera kumadziva ehove mumapindu kana nzvimbo dzevashanyi.
Inflatable aerator:Iyo yakadzika mvura, zviri nani mhedzisiro, uye yakakodzera kushandiswa mumvura yakadzika.
Inhalation aerator:Mhepo inotumirwa mumvura kuburikidza nekusveta kwakashata, uye inoumba mhepo ine mvura yekusundira mvura mberi, saka simba rekusanganisa rine simba.Simba rayo rekusimudzira okisijeni kumvura yakadzika yakasimba kupfuura iyo yeaerator impeller, uye simba rayo rekusimudzira okisijeni kumvura yekumusoro yakaderera zvishoma kune iyo impeller aerator [4].
Eddy flow aerator:Inonyanya kushandiswa kweokisijeni yemvura yakadzika kuchamhembe kweChina, ine yakakwira oxygenation inoshanda [4].
Pombi yeokisijeni:Nekuda kwehuremu hwayo, kushanda kuri nyore uye kamwechete-inosimudzira okisijeni basa, inowanzoenderana nemadziva ekurima fry kana madziva ekurima magreenhouse ane kudzika kwemvura isingasviki 0.7 metres nenzvimbo isingasviki 0.6 mu.
