HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Tsiku loperekera: Masiku 90

Kuchuluka kwa zinthu zomwe zikupezeka: Mpweya wokometsera (wopanda mafuta, Mpweya woziziritsa, Turbo expander, Oxygen Manifold, Instrument control system, Air cleansing system, distillation system, oxygen booster,)
1. Mpweya wosaphika umachokera mumlengalenga, umadutsa mu fyuluta ya mpweya kuti uchotse fumbi ndi tinthu tina ta makina ndipo umalowa mu compressor ya mpweya yosalowa mafuta kuti ikanikizidwe ndi compressor iwiri mpaka pafupifupi 0.65MPa(g). Umadutsa mu cooler ndipo umalowa mu precooling unit kuti uziziritsidwe mpaka 5~10℃. Kenako umapita ku switch-over MS purifier kuti uchotse chinyezi, CO2, carbon hydrogen. Chotsukira chimakhala ndi mitsempha iwiri yodzazidwa ndi molecular see. Chimodzi chimagwiritsidwa ntchito pamene anther ikubwezeretsedwanso ndi nayitrogeni yotayika kuchokera ku cold box komanso kudzera mu heater heating.

2. Pambuyo poyeretsedwa, gawo laling'ono la mpweya limagwiritsidwa ntchito ngati mpweya wonyamula mpweya wa turbine expander, lina limalowa m'bokosi lozizira kuti liziziritsidwe ndi reflux (oxygen yeniyeni, nitrogen yeniyeni ndi zinyalala za nayitrogeni) mu chosinthira kutentha chachikulu. Gawo lina la mpweya limachotsedwa pakati pa chosinthira kutentha chachikulu ndikupita ku turbine yowonjezera kuti ipange kuzizira. Mpweya wambiri wokulirapo umadutsa mu subcooler yomwe imaziziritsidwa ndi mpweya kuchokera pamwamba kuti iperekedwe ku gawo lapamwamba. Gawo laling'ono limadutsa mu chitoliro cha nayitrogeni chotayidwa mwachindunji ndipo chimatenthedwanso kuti chituluke m'bokosi lozizira. Gawo lina la mpweya limapitiriza kuziziritsidwa mpaka mpweya wamadzimadzi womwe umafika pansi.

3. Mu mpweya wa m'munsi, mpweya umalekanitsidwa ndi kusungunuka ngati nayitrogeni wamadzimadzi ndi mpweya wamadzimadzi. Gawo la nayitrogeni wamadzimadzi limachotsedwa pamwamba pa mzati wapansi. Mpweya wamadzimadzi ukazizira pang'ono ndi kuponderezedwa umaperekedwa pakati pa mzati wapamwamba ngati reflux.

4. Mpweya wa okosijeni umachotsedwa pansi pa chigawo chapamwamba ndikutenthedwanso ndi choziziritsira mpweya chowonjezera, chomwe ndi kusinthana kwa kutentha kwakukulu. Kenako chimatulutsidwa kuchokera pa chigawo. Nayitrogeni wotayidwa amachotsedwa pamwamba pa chigawo chapamwamba ndikutenthedwanso mu choziziritsira mpweya chachikulu ndi chosinthira kutentha chachikulu kuti chituluke pa chigawocho. Gawo lake limagwiritsidwa ntchito ngati mpweya wokonzanso wa MS purifier. Nayitrogeni woyera amachotsedwa pamwamba pa chigawo chapamwamba ndikutenthedwanso mu mpweya wamadzimadzi, choziziritsira mpweya chamadzimadzi ndi chosinthira kutentha chachikulu kuti chituluke pa chigawocho.

5. Mpweya wochokera mu mzati wa distillation umakanikizidwa kwa kasitomala.
