Kodi kutulutsa pneumatic ndi chiyani?
Pneumatic conveying ndi kunyamula zinthu zolimba kwambiri kudzera papaipi pogwiritsa ntchito mpweya kapena mpweya wina.... Mayendedwe a mpweya amatha kumangidwa ngati kupanikizika kwabwino kapena vacuum system.
Kutumiza ufa wa pneumatic kumagwiritsa ntchito mphamvu yakuyenda kwa mpweya.Kutumiza kwa mpweya kumatchedwanso kuti mpweya wotumiza kapena mpweya.Kugwiritsa ntchito ukadaulo wa fluidization kutengera zinthu za granular motsatira njira yolowera mpweya mupaipi yotsekedwa.Kapangidwe ka chipangizo chotengera pneumatic ndi chosavuta komanso chosavuta kugwiritsa ntchito.Itha kugwiritsidwa ntchito pamayendedwe opingasa, ofukula kapena oblique.Panthawi yoyendetsa, ntchito zolimbitsa thupi monga kutenthetsa, kuziziritsa, kutulutsa kowuma kowuma, kapena ntchito zina zama mankhwala zitha kuchitikanso nthawi imodzi.
Malinga ndi kachulukidwe ka tinthu tating'onoting'ono pamapaipi oyendera, mayendedwe a pneumatic amagawidwa m'magulu otsatirawa:
1. Dilute gawo kayendedwe: zolimba zili zosakwana 100kg / m3 kapena olimba-to-gasi chiŵerengero (chiŵerengero cha misa yothamanga mlingo pakati pa voliyumu yoyendetsa galimoto ndi kugwiritsira ntchito gasi) ndi 0.1-25.Kuthamanga kwa gasi ndikokwera kwambiri (pafupifupi 1830ms, malinga ndi kupanikizika kwa gasi mu payipi, kumagawidwa kukhala mtundu woyamwa ndi mtundu woperekera kuthamanga. Kutsitsidwa pansi pa kupsinjika koyipa, ndipo kumatha kunyamulidwa mozungulira. particles ayenera kutumizidwa mu payipi ya kuthamanga ndi feeder.
2. Mayendedwe a gawo la dense: kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka anthu. .Kuyenda kwapakatikati kodzaza ndi mpweya wamtundu wa dense phase.Ikani particles mu kuthamanga thanki mu magulu, ndiyeno ventilate iwo kumasula iwo.Kuthamanga mu thanki kukafika kukakamiza kwina, tsegulani valavu yotulutsa ndikuwomba tinthu tating'ono mu chitoliro chonyamulira.Kutumiza kwa pulse ndikudutsa mpweya woponderezedwa kulowa mu thanki yapansi kuti amasule zinthu;wina zimachitika wothinikizidwa mumlengalenga otaya ndi pafupipafupi 2040min-1 ndi kuwomberedwa mu polowera chakudya chitoliro, n'kupanga alternately anakonza mizati yaing'ono ndi zigawo zing'onozing'ono mu chitoliro ndime mpweya ntchito mpweya kukakamiza kukankhira patsogolo.Mayendedwe amtundu wanyimbo ali ndi mayendedwe akulu akulu, amatha kupanikizidwa mtunda wautali, kuwonongeka kwazinthu ndikusintha kavalidwe ndizochepa, komanso kugwiritsa ntchito mphamvu kumakhala kochepa.Poyendetsa mayendedwe a dilute mumayendedwe oyendera mapaipi opingasa, kuthamanga kwa gasi kuyenera kukhala kokwezeka kwambiri kuti tinthu tating'onoting'ono tituluke ndikuyimitsidwa mumayendedwe a mpweya.Posankha dilute gawo kutengera kapena wandiweyani gawo kufalitsa, amapangidwa motengera kutulutsa linanena bungwe ndi ufa zinthu ntchito.
