Kuyanika makina ozizira chowumitsira ndi aftercooler mu wothinikizidwa mpweya
Mpweya wonse wa mumlengalenga uli ndi nthunzi wa madzi: kwambiri pa kutentha kwambiri komanso pang'ono pa kutentha kochepa.Mpweya ukakanikizidwa, kuchuluka kwa madzi kumawonjezeka.Mwachitsanzo, kompresa yokhala ndi mphamvu yogwira ntchito ya 7 bar ndi kuthamanga kwa 200 l / s imatha kutulutsa madzi 10 l / h mu payipi ya mpweya woponderezedwa kuchokera ku 20 ° C mpweya wokhala ndi chinyezi cha 80%.Pofuna kupewa kusokonezedwa ndi condensation mu mapaipi ndi zipangizo zolumikizira, mpweya woponderezedwa uyenera kukhala wouma.Njira yowumitsa ikugwiritsidwa ntchito muzitsulo za aftercooler ndi zowumitsa.Mawu akuti "pressure dew point" (PDP) amagwiritsidwa ntchito pofotokoza zomwe zili mumadzi mumpweya woponderezedwa.Amatanthawuza kutentha komwe mpweya wamadzi umayamba kukhazikika m'madzi chifukwa cha kuthamanga kwapano.Kutsika kwa PDP kumatanthauza kuti mumpweya wopanikizika mumakhala nthunzi wocheperako.
Compressor yokhala ndi mpweya wokwanira 200 malita / sekondi imatulutsa pafupifupi malita 10 pa ola lamadzi okhazikika.Panthawiyi, mpweya woponderezedwa ndi 20 ° C.Chifukwa cha kugwiritsa ntchito zoziziritsa kukhosi ndi zida zowumitsa, mavuto obwera chifukwa cha condensation mu mapaipi ndi zida amapewa.
Mgwirizano wapakati pa dew point ndi pressure dew point
Chinachake choyenera kukumbukira poyerekeza zowumitsira zosiyanasiyana sikusokoneza mame am'mlengalenga ndi mame amphamvu.Mwachitsanzo, kupanikizika kwa mame pa 7 bar ndi +2 ° C ndikofanana ndi mame othamanga pa -23 ° C.Kugwiritsa ntchito fyuluta kuchotsa chinyezi (kutsitsa mame) sikugwira ntchito.Izi zili choncho chifukwa kuzirala kwina kumapangitsa kuti nthunzi yamadzi ipitirire.Mutha kusankha mtundu wa zida zowumitsa potengera mame opanikizika.Poganizira mtengo, kutsika kwa mame kumatsika, m'pamenenso ndalama zoyendetsera ntchito zowumitsa mpweya zimakwera.Pali matekinoloje asanu ochotsera chinyezi kuchokera kumpweya woponderezedwa: kuziziritsa kuphatikiza kupatukana, kuponderezana kwambiri, nembanemba, kuyamwa ndi kuyanika kwa adsorption.
aftercooler
Chotenthetsera ndi chotenthetsera chomwe chimaziziritsa gasi wotentha, zomwe zimapangitsa kuti mpweya wamadzi mu gasi wopanikizidwa wotentha ukhale m'madzi omwe angafanane ndi mapaipi.The aftercooler ndi madzi ozizira kapena mpweya wokhazikika, kawirikawiri ndi cholekanitsa madzi, chomwe chimangotulutsa madzi ndipo chimakhala pafupi ndi compressor.
Pafupifupi 80-90% ya madzi osungunuka amasonkhanitsidwa mu cholekanitsa chamadzi cha aftercooler.Kutentha kwa mpweya woponderezedwa wodutsa mu choziziritsa kuzizira nthawi zambiri kudzakhala 10°C kuposa kutentha kwa sing'anga yozizira, koma kungakhale kosiyana kutengera mtundu wa kuzizirira.Pafupifupi ma compressor onse oyima amakhala ndi choziziritsa kukhosi.Nthawi zambiri, aftercooler imamangidwa mu compressor.
Osiyanasiyana aftercoolers ndi olekanitsa madzi.Cholekanitsa madzi chingathe kulekanitsa madzi osungunuka kuchokera ku mpweya woponderezedwa posintha njira ndi liwiro la kutuluka kwa mpweya.
Chowumitsira ozizira
Kuumitsa kuzizira kumatanthauza kuti mpweya woponderezedwa umakhazikika, kufupikitsidwa ndikulekanitsidwa kukhala madzi ochulukirapo.Mpweya woponderezedwawo ukazizira ndi kufupikitsidwa, umatenthedwa mpaka kutentha kwa chipinda kachiwiri kuti condensation isabwerenso kunja kwa ductwork.Kuwotcha kutentha pakati pa wothinikizidwa mpweya polowera ndi kukhetsa osati kuchepetsa wothinikizidwa mpweya polowera kutentha, komanso kuchepetsa kuzirala katundu wa refrigerant dera.
Kuziziritsa wothinikizidwa mpweya kumafuna chatsekedwa firiji dongosolo.Compressor ya firiji yokhala ndi kuwerengera mwanzeru imatha kuchepetsa kwambiri kugwiritsa ntchito mphamvu ya chowumitsira firiji.Zipangizo zoyanika m'firiji zimagwiritsidwa ntchito pa gasi woponderezedwa ndi mame pakati pa +2 ° C ndi +10 ° C ndi malire otsika.Malire apansi awa ndi malo oundana amadzi okhazikika.Zitha kukhala chipangizo chosiyana kapena chomangidwa mu compressor.Ubwino womalizawu ndikuti umakhala ndi malo ang'onoang'ono ndipo umatha kuwonetsetsa kuti mpweya wa compressor umakhala ndi zida.
Kusintha kofananira kwa kukanikizana, kuziziritsa ndikuwumitsa
Mpweya wa refrigerant womwe umagwiritsidwa ntchito muzowumitsira firiji uli ndi mphamvu yochepa ya kutentha kwa dziko (GWP), zomwe zikutanthauza kuti pamene desiccant imatulutsidwa mwangozi mumlengalenga, sizingatheke kuyambitsa kutentha kwa dziko.Malinga ndi malamulo a chilengedwe, mafiriji amtsogolo adzakhala ndi makhalidwe otsika a GWP.
