Kuomesa maitiro einotonhora yakaoma uye aftercooler mumhepo yakamanikidzwa
Mhepo yese yemuchadenga ine mhute yemvura: yakawanda pakupisa kwakanyanya uye kushoma pakudziya kwakaderera.Kana mhepo yakamanikidzwa, kuwanda kwemvura kunowedzera.Semuenzaniso, compressor ine kushandiswa kwekushanda kwe7 bar uye kuyerera kwe200 l / s inogona kusunungura 10 l / h yemvura mupombi yemhepo yakamanikidzwa kubva ku20 ° C mhepo ine hunyoro hwe80%.Kuti udzivise kupindira ne condensation mumapombi uye midziyo yekubatanidza, mhepo yakamanikidzwa inofanira kunge yakaoma.Iyo yekuomesa maitiro inoshandiswa mune aftercooler uye yekuomesa michina.Izwi rekuti "pressure dew point" (PDP) rinoshandiswa kutsanangura zviri mukati memvura mumhepo yakamanikidzwa.Rinoreva tembiricha apo mhute yemvura inotanga kunyungudika ichienda mumvura panguva yekushanda.A low PDP value zvinoreva kuti kune mhute shoma yemvura mumhepo yakamanikidzwa.
Compressor ine mhepo inokwana 200 litres/sekondi inoburitsa anenge 10 litres/awa emvura yakakonyedzwa.Panguva ino, mweya wakatsikirirwa uri 20°C.Nekuda kwekushandiswa kweanotonhorera uye midziyo yekuomesa, matambudziko anokonzerwa nekunyungudika mumapombi uye michina inodziviswa.
Hukama pakati pedova uye pressure dew point
Chimwe chinhu chekuyeuka kana uchienzanisa maomesi akasiyana hakusi kuvhiringa dova remuchadenga nekumanikidza kwedova.Semuenzaniso, dzvinyiriro yedova pa7 bar uye +2 ° C yakaenzana neyakajairwa kumanikidza dova pa -23 ° C.Kushandisa sefa kubvisa unyoro (kudzikisa dova) hakushande.Izvi zvinodaro nekuti kumwe kutonhora kunokonzeresa kuenderera mberi kwehutsi hwemvura.Iwe unogona kusarudza rudzi rwemichina yekuomesa zvichienderana nekumanikidzwa kwedova point.Kana uchifunga nezvemutengo, kuderera kwedova kunodiwa, ndiko kuwedzera kwekudyara uye mari yekushandisa yekuomesa mhepo.Kune matekinoroji mashanu ekubvisa hunyoro kubva kumhepo yakadzvanywa: kutonhora pamwe nekuparadzanisa, overcompression, membrane, kunyura uye adsorption kuomesa.
aftercooler
An aftercooler mutsinhanisi wekupisa unotonhodza gasi rinopisa rakaminyirirwa, richibvumira mhute yemvura mugasi rinopisa rakadzvanywa kuti ripinde mumvura iyo yaizokoira mupombi.Iyo aftercooler inotonhorera mvura kana mhepo, kazhinji ine separator yemvura, iyo inongotora mvura uye iri pedyo ne compressor.
Inenge 80-90% yemvura yakanyungudutswa inounganidzwa mumvura inoparadzanisa ye aftercooler.Tembiricha yemhepo yakadzvanyirirwa inopfuura nemu aftercooler inowanzove 10°C yakakwira kupfuura tembiricha yemhepo yekutonhodza, asi inogona kusiyana zvichienderana nerudzi rwekutonhora.Anenge ese akamira compressor ane aftercooler.Muzviitiko zvakawanda, iyo aftercooler inovakwa mu compressor.
Different aftercoolers uye water separators.Muparadzi wemvura unogona kuparadzanisa mvura yakanyungudutswa kubva kumhepo yakamanikidzwa nekushandura kwakananga nekumhanya kwekuyerera kwemhepo.
Cold dryer
Kuomeswa nechando kunoreva kuti mweya wakadzvanywa unotonhodzwa, kupfupfunyurwa uye wopatsanurwa kuita mvura yakawanda.Mushure mekunge mhepo yakamanikidzwa yatonhorera uye yakadzivirirwa, inopisa kusvika kune tembiricha yekamuri zvakare kuitira kuti condensation irege kuitika zvakare kunze kweiyo ductwork.Kutsinhana kwekupisa pakati peiyo compressed air inlet uye kubuda haingogone kuderedza tembiricha yemhepo inopinza, asi zvakare inoderedza kutonhora kwedunhu refiriji.
Kutonhodza mhepo yakamanikidzwa inoda yakavharwa firiji system.Iyo firiji compressor ine hungwaru kuverenga kutonga inogona kuderedza zvakanyanya kushandiswa kwesimba kwefiriji yakaoma.Refrigerant drying equipment inoshandiswa kune yakamanikidzwa gasi ine dova pakati pe +2 ° C uye +10 ° C uye yakaderera muganhu.Uyu muganho wepasi ndiyo nzvimbo yekutonhora yemvura yakakonyedzwa.Vanogona kuve mudziyo wakasiyana kana wakavakirwa mucompressor.Kubatsira kweiyo yekupedzisira ndeyekuti inotora nzvimbo diki uye inogona kuve nechokwadi chekushanda kwemhepo compressor iyo yakashongedzerwa nayo.
Yakajairika parameter shanduko yekumanikidza, post-kutonhora uye nechando-kuomesa
Iyo gasi refiriji rinoshandiswa mumafiriji akaomeswa ane hushoma hwekudziya kwepasirese (GWP), zvinoreva kuti kana desiccant yaburitswa netsaona mumhepo, haigone kukonzera kudziya kwepasirese.Sezvinotsanangurwa mumutemo wezvakatipoteredza, mafiriji emangwana achave akaderera GWP.
