HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Nsanja yolekanitsa mpweya ndi chipangizo chofunikira chomwe chimagwiritsidwa ntchito kulekanitsa zigawo zazikulu za mpweya mumlengalenga kukhala nayitrogeni, mpweya, ndi mpweya wina wosowa. Kuyenda kwake kumaphatikizapo njira monga kupondereza mpweya, kuziziritsa, kuyeretsa, kuziziritsa, ndi kusungunuka. Kuwongolera kolondola kwa gawo lililonse ndikofunikira kwambiri kuti zitsimikizire kuti zinthu zomaliza za mpweya zimakhala zoyera komanso zokhazikika. Nkhaniyi ipereka chiyambi chatsatanetsatane cha kuyenda kwa njira ya nsanja yolekanitsa mpweya.

1. Kupondereza Mpweya ndi Kuziziritsa Pasadakhale

Gawo loyamba mu ndondomeko yolekanitsa mpweya ndi kupondereza mpweya wa mumlengalenga. Kudzera m'magawo angapo a ma compressor a mpweya, mpweya umaponderezedwa kufika pa 5-7 bar. Panthawi yopondereza, kutentha kwa mpweya woponderezedwa kumakweranso, kotero ma cooler apakatikati ndi ma post-cooler amagwiritsidwa ntchito kuchepetsa kutentha kwa mpweya. Pofuna kupewa kuti compressor isawonongeke ndi zinyalala mumlengalenga, tinthu ta mumlengalenga timachotsedwa kudzera mu zosefera. Mpweya woponderezedwa umatumizidwa ku makina oziziritsira asanayambe kuzizira kuti uziziritsenso, nthawi zambiri pogwiritsa ntchito madzi ozizira kapena ma refrigerant monga Freon, kuti uziziritse mpweya kufika pafupifupi 5°C.

2. Kuyeretsa Mpweya ndi Kutaya Madzi M'thupi

Pambuyo poziziritsa mpweya, mpweya umakhala ndi chinyezi pang'ono ndi carbon dioxide. Zonyansa zimenezi zimatha kupanga ayezi pa kutentha kochepa komanso zida zotchingira. Chifukwa chake, mpweya umafunika kuyeretsedwa ndikuumitsa madzi. Njira imeneyi nthawi zambiri imagwiritsa ntchito ma molecular sieve adsorption towers, kudzera mu njira zoziziritsira mpweya nthawi ndi nthawi kuti ichotse nthunzi ya madzi, carbon dioxide, ndi ma hydrocarbon, ndi zina zotero, kuti zitsimikizire kuti njira zoziziritsira mpweya zomwe zikubwerazi zikuyenda bwino. Mpweya woyeretsedwawo ndi woyera komanso wouma, woyenera njira zoziziritsira komanso zolekanitsa mpweya pambuyo pake.

3. Chosinthira Kutentha Chachikulu Choziziritsa Mpweya

Mpweya woyeretsedwa umaziziritsidwa mu chosinthira kutentha chachikulu kudzera mu kuziziritsa kwambiri. Chosinthira kutentha chachikulu ndi chimodzi mwa zida zofunika kwambiri pa ndondomeko yolekanitsa mpweya. Mpweya mu chosinthira kutentha chachikulu umasinthidwa kutentha ndi nayitrogeni yozizira yolekanitsidwa ndi mpweya, zomwe zimachepetsa kutentha kwake kufika pafupi ndi kutentha kwa madzi. Kugwira ntchito bwino kwa kusinthana kutentha panthawiyi kumakhudza mwachindunji kugwiritsa ntchito mphamvu ndi kuyera kwa chinthu chomaliza cha nsanja yolekanitsa mpweya. Nthawi zambiri, zosinthira kutentha za aluminiyamu zimagwiritsidwa ntchito bwino kuti ziwongolere kugwira ntchito bwino kwa kusinthana kutentha.

4. Njira Yopatukana mu Nsanja Yoyeretsera

Mpweya wozizira umatumizidwa ku nsanja yoyeretsera kuti ulekanitsidwe pogwiritsa ntchito kusiyana kwa malo otentha a zigawo zosiyanasiyana mumlengalenga. Mpweyawo umasungunuka pang'onopang'ono kutentha kochepa, ndikupanga mpweya wamadzimadzi. Mpweya wamadzimadziwu umalowa mu nsanja yoyeretsera kuti ugwirizane ndi magawo ambiri a mpweya ndi madzi. Mu nsanja yoyeretsera, mpweya, nayitrogeni, ndi mpweya wosowa monga argon zimalekanitsidwa. Kuchuluka kwa mpweya kumawonjezeka pang'onopang'ono pansi pa nsanja, pomwe nayitrogeni imalekanitsidwa pamwamba. Kudzera mu kuyeretsa, mpweya woyera ndi nayitrogeni zimatha kupezeka ndi chiyero chapamwamba.

5. Kutulutsa Mpweya ndi Zinthu za Nayitrogeni

Kutulutsa mpweya ndi nayitrogeni ndi gawo lomaliza la nsanja yolekanitsa mpweya. Mpweya wamadzimadzi ndi nayitrogeni zimalekanitsidwa ndi nsanja yoyeretsera madzi ndikutenthedwanso kutentha kwa chipinda kudzera mu zosinthira kutentha kuti zifike pamalo omwe mukufuna. Zinthu za mpweyazi zimatumizidwanso ku matanki osungiramo zinthu kapena zimaperekedwa mwachindunji kwa ogwiritsa ntchito. Kuti zinthu ziyende bwino komanso kuti zinthu zikhale zoyera, nthawi zina kapangidwe ka nsanja ziwiri kamapangidwa kuti kalekanitse argon ndi mpweya ndi nayitrogeni kuti zigwiritsidwe ntchito m'mafakitale.

6. Kulamulira ndi Kukonza Zinthu

Njira yonse yolekanitsa mpweya imakhala ndi njira yovuta yowongolera, yomwe imafuna kuyang'anira nthawi yeniyeni ndikusintha njira zopondereza, kuziziritsa, kusinthana kutentha, ndi kulekanitsa kuti zitsimikizire mtundu wa zinthu zomaliza. Nsanja zamakono zolekanitsa mpweya nthawi zambiri zimakhala ndi makina owongolera okha, pogwiritsa ntchito masensa ndi mapulogalamu owongolera kuti azilamulira molondola magawo monga kutentha, kuthamanga, ndi kuyenda kuti akonze bwino momwe ntchito yopangira imagwiritsidwira ntchito mphamvu komanso kuyera kwa zinthu za mpweya.

Kuyenda kwa njira yolekanitsira mpweya kumaphatikizapo masitepe angapo monga kupondereza mpweya, kuziziritsa mpweya, kuyeretsa, kuziziritsa kwambiri, ndi kusungunuka. Kudzera mu njirazi, mpweya, nayitrogeni, ndi mpweya wosowa mumlengalenga zimatha kulekanitsidwa bwino. Kukula kwa ukadaulo wamakono wolekanitsa mpweya kwapangitsa kuti njira yolekanitsira mpweya ikhale yogwira mtima komanso yogwiritsa ntchito mphamvu zochepa, zomwe ndizofunikira kwambiri pakugwiritsa ntchito mpweya wa mafakitale.

Ngati mukufuna mpweya/nayitrogeni, chonde titumizireni uthenga:
