Wolekanitsa fumbi la Whirlwind F-300
Mawu Oyamba
Cyclone fumbi chotolera ndi mtundu wa chipangizo kuchotsa fumbi.The dedusting limagwirira ndi kupanga fumbi kubala mpweya kuyenda atembenuza, fumbi particles analekanitsidwa ndi mpweya otaya ndi mphamvu centrifugal ndi kusonkhanitsa pa khoma la chipangizo, ndiyeno fumbi particles kugwera mu fumbi hopper ndi mphamvu yokoka.Chigawo chilichonse cha mkuntho fumbi wotolera ali ndi kukula kwake gawo, ndi kusintha kwa gawo lililonse ubale zingakhudze dzuwa ndi kuthamanga imfa ya chimphepo fumbi wotolera, amene awiri a fumbi wotolera, kukula kwa mpweya polowera ndi awiri a utsi chitoliro. ndizo zikuluzikulu zomwe zimalimbikitsa.Pogwiritsidwa ntchito, ziyenera kudziwidwa kuti ubwino ukhozanso kusinthidwa kukhala zovuta pamene malire ena adutsa.Kuonjezera apo, zinthu zina ndizopindulitsa kupititsa patsogolo fumbi kuchotsa fumbi, koma zidzawonjezera kutaya kwa kuthamanga, kotero kusintha kwa chinthu chilichonse chiyenera kuganiziridwa.
Wotolera fumbi la Cyclone adayamba kugwiritsidwa ntchito mu 1885 ndipo apanga mitundu yambiri.Malinga ndi njira yolowera mpweya, imatha kugawidwa m'mitundu yolowera komanso mtundu wa axial.Pansi pa kutayika kofanana komweko, wotsirizirayo amatha kuthana ndi gasi wochulukira katatu kuposa woyamba, ndipo kugawa kwake kumakhala kofanana.
Wotolera fumbi la Cyclone amapangidwa ndi chitoliro cholowera, chitoliro chotulutsa mpweya, silinda, chulucho ndi chopumira.Wotolera fumbi la Cyclone ndi losavuta kupanga, losavuta kupanga, kuyika ndi kukonza kasamalidwe, ndalama zogulira zida ndi ndalama zogwirira ntchito ndizotsika, zakhala zikugwiritsidwa ntchito kwambiri kulekanitsa tinthu tating'ono tolimba ndi tamadzi timene timatulutsa mpweya, kapena tinthu tating'onoting'ono tamadzi.Pazikhalidwe zogwirira ntchito, mphamvu ya centrifugal yomwe imagwira ntchito pa tinthu ting'onoting'ono ndi 5 ~ 2500 nthawi yokoka, kotero kuti mphamvu ya otolera fumbi yamkuntho ndiyokwera kwambiri kuposa ya chipinda chokhazikitsa mphamvu yokoka.Kutengera mfundo iyi, chida chochotsa fumbi chopitilira 90% chida chochotsa fumbi chamkuntho chaphunziridwa bwino.Mu makina otolera fumbi, wotolera fumbi wa chimphepo ndi mtundu wachangu kwambiri.Ndi oyenera kuchotsa fumbi sanali viscous ndi sanali fibrous, makamaka ntchito kuchotsa kuposa 5μm particles, kufanana Mipikisano chitoliro fumbi wotolera chipangizo kwa 3μm particles alinso 80 ~ 85% fumbi kuchotsa dzuwa.Chotolera fumbi chamkuntho chimapangidwa ndi chitsulo chapadera kapena zida za ceramic zokhala ndi kutentha kwambiri, kukana kwa abrasion komanso kukana dzimbiri.Itha kuyendetsedwa ndi kutentha mpaka 1000 ℃ ndikukakamiza mpaka 500 × 105Pa.Pankhani yaukadaulo ndi zachuma, kuwongolera kutayika kwamphamvu kwa otolera fumbi lachimphepo nthawi zambiri kumakhala 500 ~ 2000Pa.Choncho, ndi wa sing'anga zotsatira fumbi wokhometsa, ndipo angagwiritsidwe ntchito kuyeretsa mkulu kutentha chitoliro mpweya, ndi ankagwiritsa ntchito fumbi wotolera, makamaka ntchito kukatentha chitoliro fumbi kuchotsa fumbi, Mipikisano siteji kuchotsa fumbi ndi chisanadze fumbi kuchotsa. .Kuipa kwake kwakukulu ndi zotsatira zake pa tinthu tating'onoting'ono ta fumbi.Kuchotsa bwino kwa 5μm) kunali kochepa.
Oyenera mitundu yonse ya mafakitale kuwongolera fumbi
