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 muzitsulo zazikulu zowonongeka mu nsanja yolekanitsa mlengalenga, umakhazikika mpaka kutentha kwa machulukitsidwe ndi mpweya wa reflux (chinthu cha nayitrogeni, mpweya wotayirira), ndipo umatumizidwa pansi pa nsanja yokonzanso, pomwe nayitrogeni imapezeka pamwamba pa nsanja, ndipo mpweya wamadzimadzi umagwedezeka ndikutumizidwa pansi pa nsanja yokonzanso. Lowani mu evaporator condensation kuti asamasanduke nthunzi, ndipo nthawi yomweyo condense gawo la nayitrogeni wotumizidwa kuchokera ku nsanja yokonzanso, gawo la nayitrogeni wamadzimadzi amagwiritsidwa ntchito ngati madzi a reflux a nsanja yokonzanso, ndipo gawo lina limatulutsidwa kuchokera ku nsanja yolekanitsa mpweya ngati mankhwala amadzimadzi a nayitrogeni.

Mpweya wotulutsa mpweya wochokera ku evaporator 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, kenako 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 nayitrogeni wa cryogenic kumatha kutulutsa nayitrogeni ndi chiyero cha ≧ 99.999%.

Ndibwino kuti mukuwerenga
