Kampani ya BH yapanga chatsopano chotolera fumbi chamitundu yambirimbiri (XX chubu).Chubu limodzi limatha kupirira kuchuluka kwa mpweya wa 1000 m3 / h, zomwe zitha kupititsa patsogolo kulekana kwa cholekanitsa chotsalira cha pellet ndikuwonetsetsa kukhazikika kwa voliyumu ya mpweya ndi kuthamanga kwa mpweya pamalo olekanitsa olekanitsa.
Multi-tube cyclone fumbi wotolera ndi mtundu wa otolera fumbi.Njira yochotsera fumbi ndikupangitsa kuti mpweya wokhala ndi fumbi ukhale wozungulira, ndipo tinthu tating'onoting'ono timasiyanitsidwa ndi mpweya ndi mphamvu ya centrifugal ndikutsekeredwa pakhoma, ndiyeno fumbi limagwera mu phulusa la phulusa ndi mphamvu yokoka.
Wotolera fumbi wamba wa cyclone amapangidwa ndi mapaipi osavuta, a cone ndi omwe amalowetsa komanso kutulutsa mpweya.Wotolera fumbi la mkuntho ali ndi mawonekedwe osavuta, ndi osavuta kupanga, kukhazikitsa, kusamalira ndi kuyang'anira, ndipo ali ndi ndalama zotsika mtengo zogulira zida ndi ntchito.Zakhala zikugwiritsidwa ntchito kwambiri kulekanitsa tinthu tating'ono tolimba ndi tamadzi timene timatulutsa mpweya, kapena tinthu tating'onoting'ono tamadzimadzi.Pazikhalidwe zogwirira ntchito, mphamvu ya centrifugal yomwe imagwira ntchito pazigawozi ndi 5 mpaka 2500 nthawi yokoka, kotero kuti mphamvu ya chimphepo yamkuntho yamachubu ambiri imakhala yokwera kwambiri kuposa ya chipinda chokhazikitsa mphamvu yokoka.Amagwiritsidwa ntchito kwambiri pochotsa tinthu tating'ono pamwamba pa 3μm, chipangizo chofananira chamitundu ingapo chilinso ndi 80-85% yochotsa fumbi kwa tinthu tating'ono ta 3μm.
mfundo yogwira ntchito
Njira yochotsera fumbi ya multitube cyclone fumbi lotolera ndikupangitsa kuti mpweya wokhala ndi fumbi ukhale wozungulira, ndipo tinthu tating'onoting'ono timasiyanitsidwa ndi kutuluka kwa mpweya ndi mphamvu ya centrifugal ndikutsekeredwa pakhoma, ndiyeno tinthu tating'onoting'ono timagwera mkati. phulusa ndi mphamvu yokoka.Mipikisano yamachubu cyclone yapangidwa kukhala mitundu yosiyanasiyana.Kutengera momwe amalowera, imatha kugawidwa m'mitundu yolowera komanso mtundu wa axial.Pansi pa kupsinjika komweko, mpweya womwe womalizayo amatha kuwongolera amakhala pafupifupi 3 nthawi zakale, ndipo kutuluka kwa gasi kumagawidwa mofanana.Wotolera fumbi wamba wa cyclone amapangidwa ndi mapaipi osavuta, a cone ndi omwe amalowetsa komanso kutulutsa mpweya.Wotolera fumbi la mkuntho ali ndi mawonekedwe osavuta, ndi osavuta kupanga, kukhazikitsa, kusamalira ndi kuyang'anira, ndipo ali ndi ndalama zotsika mtengo zogulira zida ndi ntchito.Zakhala zikugwiritsidwa ntchito kwambiri kulekanitsa tinthu tating'ono tolimba ndi tamadzi timene timatulutsa mpweya, kapena tinthu tating'onoting'ono tamadzimadzi.Pazikhalidwe zogwirira ntchito, mphamvu ya centrifugal yomwe imagwira ntchito pazigawozi ndi 5 mpaka 2500 nthawi yokoka, kotero kuti mphamvu ya chimphepo yamkuntho yamachubu ambiri imakhala yokwera kwambiri kuposa ya chipinda chokhazikitsa mphamvu yokoka.Amagwiritsidwa ntchito kwambiri kuchotsa tinthu tating'ono pamwamba pa 0.3μm, chipangizo chamkuntho chofananira chamitundu yambiri chimakhalanso ndi 80-85% kuchotsa fumbi kwa tinthu tating'ono ta 3μm.Chotolera chamkuntho chopangidwa ndi chitsulo chapadera kapena zida za ceramic kugonjetsedwa ndi kutentha kwakukulu, kuvala ndi dzimbiri ndi zovala zimatha kuyendetsedwa ndi kutentha mpaka 1000 ℃ ndikukakamiza mpaka 500 × 105Pa.Poganizira zaukadaulo ndi zachuma, kuwongolera kwamphamvu kwa osonkhanitsa fumbi lachimphepo nthawi zambiri kumakhala 500-2000Pa.Multi-tube cyclone fumbi wotolera amatanthawuza kuti angapo otolera fumbi chimphepo amagwiritsidwa ntchito limodzi kuti apange gulu lophatikizika ndikugawana zipinda zodyera ndi zotulutsa, komanso phulusa wamba kupanga chotolera fumbi lamitundu yambiri.Mphepo yamkuntho iliyonse yomwe ili mumkuntho wa machubu angapo iyenera kukhala yocheperako komanso yocheperako, ndipo m'mimba mwake isakhale yaying'ono chifukwa ndi yaying'ono kwambiri kuti isatsekeke.
Multi-tube cyclone fumbi chotolera ndi chimphepo chamkuntho chotolera ndi mpweya wachiwiri wowonjezeredwa.Mfundo yake yogwira ntchito ndi yakuti pamene mpweya umazungulira mu chipolopolo chosonkhanitsa fumbi, mpweya wachiwiri umagwiritsidwa ntchito kulimbikitsa kusinthasintha kwa mpweya woyeretsedwa kuti ukhale wabwino kuchotsa fumbi.Pali njira ziwiri zokwaniritsira kusinthasintha uku, ndikutulutsa fumbi mu phulusa la phulusa.Njira yoyamba ndiyo kunyamula mpweya wachiwiri kudzera potsegula mwapadera pamphepete mwa chipolopolocho pamtunda wa madigiri 30-40 kuchokera kumtunda.
Njira yachiwiri ndiyo kunyamula mpweya wachiwiri kudzera mu mpweya wa annular oblique oyenda ndi masamba okhotakhota kuti azungulire mpweya woyeretsedwa.Kuchokera pazachuma, gasi wokhala ndi fumbi angagwiritsidwe ntchito ngati mpweya wachiwiri.Pamene mpweya woyeretsedwa uyenera kuziziritsidwa, nthawi zina mpweya wakunja ungagwiritsidwe ntchito kuuzunguliza.Magawo aukadaulo a osonkhanitsa fumbi la cyclone ali pafupi ndi chimphepo wamba.
Pakalipano, kugwiritsa ntchito kuchotsa fumbi lolowera mpweya m'migodi ndi m'mafakitale kwawonetsa bwino.Gawo lina laling'ono la mpweya wolowera mumlengalenga wa mvula yamkuntho yamachubu ambiri lidzasunthira pamwamba pa chiwombankhanga chamitundu yambiri, kenako ndikutsika kunja kwa chitoliro chotulutsa mpweya.Kukwera kwapakati kwa mpweya kumatulutsidwa kuchokera ku chitoliro cha mpweya pamodzi ndi kutuluka kwapakati kwa mpweya, ndipo fumbi lomwe limabalalika mmenemo limachotsedwanso.Pambuyo pozungulira mpweya amafika pansi pa chulucho.Tembenukirani m'mbali mwa osonkhanitsa fumbi.Kuthamanga kwa mpweya wokwera mkati kumapangidwira ndikutulutsidwa ndi chitoliro chotulutsa fumbi.Kuchita bwino kochotsa fumbi kumatha kufika kupitilira 80%, ndipo wotolera fumbi wapadera wachitika bwino m'zaka zaposachedwa.Kutulutsa kwake fumbi kumatha kufika kuposa 5%.Mpweya wambiri wozungulira umakhala wozungulira pakhoma, umayenda kuchokera pamwamba mpaka pansi mpaka pansi pa chulucho, ndikupanga kutuluka kwakunja kozungulira komwe kumakhala fumbi.
Mphamvu ya centrifugal yomwe imapangidwa panthawi yozungulira kwambiri idzafalitsa kachulukidwe kutali Tinthu tating'ono ta mpweya timaponyedwa ku khoma la chidebecho.Kamodzi fumbi particles kukumana ndi khoma, iwo kutaya inertial mphamvu ndi kudalira mphamvu ya polowera liwiro ndi mphamvu yokoka kugwa mu phulusa chopereka Hopper pa khoma.Multi-tube cyclone fumbi chotola fumbi ndi chimphepo chamkuntho chokhala ndi mikuntho ingapo yolumikizidwa mofanana.Kugwiritsiridwa ntchito kofala kwa mapaipi olowera ndi ndowa za phulusa.Ndikofunikira kupanga liwiro la mpweya wa chotengera cha fumbi.Nthawi zambiri osachepera 18m / s.Ngati ndi otsika kwambiri, kukonza bwino kuchepetsedwa, ndipo pali ngozi yotseka.Ngati ndipamwamba kwambiri, chimphepocho chidzavala kwambiri ndipo kukana kumawonjezeka kwambiri.Kuchotsa fumbi sikudzasintha kwambiri.Mphepo yamkuntho yamachubu ambiri ilibe magawo ozungulira komanso kuvala, kotero ndiyosavuta kugwiritsa ntchito ndikusamalira.Mphepo yamkuntho ndi gawo lamkati la multi-tube cyclone fumbi lotolera, lomwe ndi lofanana ndi thumba la fumbi losefera la otolera fumbi.Malinga ndi momwe amagwiritsidwira ntchito, zida zosiyanasiyana zitha kugwiritsidwa ntchito popanga mvula yamkuntho, monga mbale zachitsulo.Mukagwiritsidwa ntchito motsatizana ndi wotolera fumbi wochita bwino kwambiri, chimphepocho chimayikidwa kutsogolo.Fumbi lomwe limatulutsidwa kudzera pakuchotsa fumbi lonse limatha kukwaniritsa miyezo yautsi yomwe yafotokozedwa ndi State Environmental Protection Administration.
