Profile yekambani
Iyo yemvura nitrogen unit yakagadziridzwa neyuniti yedu inotora Pressure Swing Adsorption (PSA) kugadzirira yakachena nitrogen, iyo inozodzorwa neyakasanganiswa-gasi joule-thomson Refrigeration Cycle, MRC kwenguva pfupi) kugadzira iyo inodiwa mvura nitrogen.
Operating Principles
Tichitaura nezvefiriji inoratidzwa muMufananidzo 1, maitiro ayo ekushanda ndeiyi: yakaderera-pressure fluid refrigerant pane ambient tembiricha T0 (inoenderana nestate point 1s) inomanikidzwa kuita gasi rinopisa rinopisa (state point 2) necompressor, uye yobva yapinda muchitonhodza, etc. Yakatonhodzwa kusvika kune ambient tembiricha (point 3), inopinda mu regenerative heat exchanger, inowedzera kutonhodzwa nereflux yakaderera-kudzvanya gasi rekushisa kusvika kustate point 4, inopinda mu throttle valve, adiabatic throttling kunongedza. 5, tembiricha inodonha, uye inopinda muevaporator kuti ipe kutonhora Kana tembiricha yakwira kusvika kunongedzo 6, inopinda muchikamu chepasi-yekudzvanya cheiyo regenerative heat exchanger, uye ichitonhodza kuyerera kwakanyanya kunouya, tembiricha yaro inodzokera zvishoma nezvishoma kune point. 1, wobva wapinda mupombi inobatanidza kupisa kupisa uye compressor. Panogona kunge paine chikamu chehurongwa panguva ino Heat leakage, tembiricha inokwira kusvika kune ambient tembiricha, inodzokera kunzvimbo yenzvimbo kwesekondi 1, uye sisitimu inopedza kutenderera. Iyo firiji system zvishoma nezvishoma inodzikisa tembiricha zvinoenderana neiri pamusoro pekuita, uye pakupedzisira inopa firiji kugona pane yakatarwa firiji tembiricha Tc. Kune yakagoverwa tembiricha inotonhora kutonhora, iyo yekutonhodza simba inopihwa zvishoma nezvishoma panguva yereflux process, seyakasikwa gasi liquefaction, nezvimwe.
Hunhu hwemusanganiswa refrigerant throttling firiji
1) Kurumidza kutanga-up uye nekukurumidza kutonhora kutonhora. Kuburikidza neyakasanganiswa refrigerant yekumisikidza ratio, compressor kugona kugadzirisa uye throttle valve kuvhura kutonga, nekukurumidza kutonhora zvinodiwa zvinogona kuwanikwa;
2) Iyo nzira iri nyore, nhamba yemidziyo idiki, uye kuvimbika kwehurongwa kwakakwira. Izvo zvikamu zvikuru zvehurongwa zvinotora akakura compressors, kupisa exchangers uye zvimwe midziyo mufiriji munda. Iyo sisitimu ine kuvimbika kwepamusoro uye huwandu hwakawanda hwemidziyo masosi.
Mutengo wekuvandudza weiyo yakasanganiswa refrigerant liquid nitrogen unit inonyanya kusanganisira zvikamu zviviri: PSA nitrogen jenareta unit uye MRC liquefaction unit. Iyo PSA nitrogen jenareta yakakura uye iri nyore kutenga mumusika wepamba.
