Mafotokozedwe Akatundu
Makina osakanizika a nayitrogeni osakanikirana amachokera pamakina osinthira a firiji. Kuyambira kutentha kozungulira kuti mulowetse kutentha kwa firiji, malo otentha, apakatikati ndi otsika otentha amakhala osakanikirana ndi mafiriji angapo, kuti madera ozizira otentha azigundana. Mwa njira iyi, kutentha kwa magawo ozizira komwe kumagawidwa kumakwaniritsidwa, ndipo kutentha kozizira kotentha komwe kumafanana ndi gawo lililonse lotentha kumakwaniritsidwa, potero pozindikira firiji yokhala ndi kutentha kwakukulu, ndipo kuzirala kwa firiji kumatha kupezeka pansi pochepera pang'ono kwakanthawi. Chifukwa chake, kompresa wokhwima m'modzi wozizira m'munda wozizira wambiri amatha kugwiritsidwa ntchito kuyendetsa firiji yosakanikirana yosakanikirana ndi firiji kuti akwaniritse firiji yotsika kwambiri.
Tekinoloji yosakanizika yomwe yatchulidwa pamwambapa yagwiritsidwa ntchito m'malo ambiri ogwiritsa ntchito komanso mafakitale. Mwachitsanzo, mumafakitale achilengedwe amtundu wa gasi, njira zosakanizirana za firiji yozizira imakhala pamalo opambana. Pazida zamagetsi zogwiritsira ntchito ndi sikelo yomwe ikukhudzidwa ndi ntchitoyi, zida zokhwima monga ma compressor ndiosinthitsa kutentha m'malo ozizira zitha kutengedwa kuti zithetse kudalirika kwadongosolo, ndipo zida zamagetsi ndizochulukirapo ndipo mtengo wake ndi wotsika.
Makhalidwe a firiji wosakanizika wopindika
1) Kuyamba kwachangu komanso kuzirala mwachangu. Kupyolera mu chiŵerengero chosakanikirana cha refrigerant, kusintha kwa kompresa ndi kutsegulira kwa ma valavu, zofunikira kuziziritsa mwachangu zimatheka;
2) Njirayi ndiyosavuta, kuchuluka kwa zida ndizochepa, ndipo kudalirika kwadongosolo ndikokwera. Zida zazikuluzikulu za dongosololi zimakhala ndi ma compressor okhwima, zotenthetsera kutentha ndi zida zina m'munda wa firiji. Makinawa ndi odalirika kwambiri komanso zida zosiyanasiyana.
Zizindikiro zaukadaulo ndi zofunikira pakugwiritsa ntchito
Kutentha kozungulira: mpaka 45 ℃ (chilimwe)
Kutalika: 180 mita
Kutulutsa kwa nayitrogeni wamadzi: 3L / h mpaka 150L / h
Jenereta ya nayitrogeni ya PSA imagwiritsa ntchito mpweya ngati zinthu zopangira, mpweya wabwino kwambiri wa mpweya monga adsorbent, umagwiritsa ntchito mfundo ya kukakamiza kugwedeza, imagwiritsa ntchito sieve yodzaza ndi ma micropores kuti isankhe bwino mpweya kuti ukwaniritse cholinga cha kupatukana kwa oxygen ndi nayitrogeni, ndi amapanga kuyera kwambiri kwa nayitrogeni makamaka zimaphatikizapo zida monga ma air compressors, zosefera, akasinja othyola, zowumitsa zowumitsa, nsanja zotsatsira, ndi akasinja osungira nayitrogeni.
MRC mayunitsi amadzimadzi amaphatikizira pre-kuzirala kompresa mayunitsi, pre-yozizira mpweya wozizira, mainkuziziritsa mayunitsi opangira ma compressor, main kuzirala kompresa mayunitsi, main ozizira mpweya ozizira, mabokosi ozizira, matanki amadzimadzi a nayitrogeni, machitidwe a BOG obwezeretsa ndi machitidwe owongolera. Choyimira chachikulu / chisanadze kuziziritsa chophatikizira chimaphatikizapo chojambulira chachikulu / chozizira chojambulira ndi mafuta ake olekanitsa mafuta, mafuta osakaniza mafuta, opangira mpweya adsorber, mafuta oyendera pampu ndi akasinja osungira firiji, ndi zina zambiri. Ntchito ya MRC ndikugwiritsa ntchito mfundo yosakanikirana kwamafuta osinthika ophatikizika kuti atulutse firiji kuti asafe. Kutentha kochepa kwa chipangizocho kumatha kufikira -180 ° C.
