1. Kuponderezana kwa mpweya ndi kuyeretsa

Mpweya umalowa mu kompresa ya mpweya pambuyo pochotsa fumbi ndi zonyansa zamakina kudzera mu fyuluta ya mpweya, kukakamizidwa kukakamiza kofunikira, kenako kutumizidwa ku choziziritsa mpweya kuti muchepetse kutentha kwa mpweya.Kenako lowetsani choyeretsa chowumitsa mpweya kuti muchotse chinyezi, mpweya woipa, acetylene ndi ma hydrocarbon ena mumlengalenga.

2. Kupatukana kwa mpweya

Mpweya woyeretsedwa umalowa m'malo otenthetsera kutentha munsanja yolekanitsa mpweya, umakhazikika mpaka kutentha kwamafuta ndi mpweya wa reflux (nayitrogeni wamafuta, mpweya wotayirira), ndipo umatumizidwa pansi pa nsanja yokonzanso, pomwe nayitrogeni imapezeka pamwamba. wa nsanja, ndi madzi mpweya mpweya ndi throttled ndiyeno kutumizidwa pansi pa nsanja rectification.Lowetsani evaporator ya condensation kuti isungunuke, ndipo nthawi yomweyo tsitsani gawo la nayitrogeni lomwe limatumizidwa kuchokera ku nsanja yokonzanso, gawo la nayitrogeni wamadzimadzi amagwiritsidwa ntchito ngati madzi a reflux a nsanja yokonzanso, ndipo gawo linalo limatulutsidwa kuchokera kulekanitsa mpweya. nsanja ngati mankhwala amadzimadzi nayitrogeni.

Mpweya wotulutsa mpweya wochokera ku evaporator wokometsera umatenthedwanso mpaka pafupifupi 130K ndi chowotcha chachikulu ndikulowa muzowonjezera kuti muwonjezere firiji kuti mupereke kuziziritsa kwa nsanja yolekanitsa mpweya.Gawo la mpweya wokulitsidwa umagwiritsidwa ntchito kukonzanso ndi kuzirala kwa sieve ya maselo, ndiyeno kutulutsidwa mu muffler.mpweya.

3. Kutentha kwa nayitrogeni wamadzimadzi

Nayitrogeni wamadzimadzi kuchokera ku nsanja yolekanitsa mpweya amasungidwa mu tanki yosungiramo nayitrogeni yamadzimadzi.Pamene mpweya kulekana zida ndi overhauled, madzi asafe mu thanki yosungirako amalowa vaporizer ndi usavutike mtima, ndiyeno anatumiza kwa mankhwala nayitrogeni payipi.

Kupanga kwa nayitrogeni wa Cryogenic kumatha kutulutsa nayitrogeni ndi chiyero cha ≧ 99.999%.

Ndibwino kuti mukuwerenga
