1. Izitshalo zokushiswa kukadoti ziphendula imfucuza esizungezile ibe umcebo
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ubuchwepheshe bokugaywa kabusha kwemfucuza buye bakhuthazwa ngokushesha.Isikhungo samandla okushisa imfucuza - ukutholwa okukhulu kwesayensi okungaguqula udoti omningi ube umcebo.Masiphile sihlanzekile futhi sinempilo.Amandla okushiswa kukadoti azokhiqiza umlotha wempukane nakanjani ngemva kokushiswa.Uma umlotha wempukane ungaphathwa kahle, nakanjani uzobangela ukungcoliswa kwemvelo kwesibili.
2. Ukuhlaziywa kokukhethwa kwezinhlobo zokuthuthwa kwe-pneumatic of waste incineration fly ash
Isistimu yokudlulisa igesi yomlotha iwukuthutha i-fly ash flue gas ngemva kokushiswa kukadoti endaweni yokugcina umlotha isuka ku-ash hopper yomqoqi wothuli ngemva kokuhlanzwa.Ngenxa yokuthi umlotha wezimpukane unobuthi futhi uyingozi, umnyango kazwelonke wokuvikelwa kwemvelo uthi ukuthuthwa komlotha wezimpukane kufanele kuvalwe ngaphandle kokungcoliswa kwesibili.Ngakho-ke, siklama ukusebenzisa isistimu yokudlulisa umoya womoya ukuze sidlulise umlotha wezimpukane esikhundleni sesistimu yokudlulisela eyimishini evamile.
Kunezinhlobo eziningi ze-powder pneumatic conveying kanye nokudlulisa umoya.Amasistimu okudlulisa umoya womoya angahlukaniswa abe izinhlobo: ukudlulisa ukucindezela okuhle, okungukuthi, ukudlulisa ukucindezela, ukudlulisa ukucindezela okungalungile nokudonsa, kanye nokucindezela okuhle nokubi kuhlangene ukudlulisa.
Kufanele sikhethe kanjani ukuthi iyiphi isistimu yokudlulisa esizoyisebenzisa ekudluliseni umlotha wezimpukane?
Ukuhanjiswa kwe-negative pneumatic:
Lolu hlelo lusebenzisa amandla omoya, okusho ukuthi, amandla asemoyeni, ukuthutha izinto ezivela endaweni eyodwa ziyise esiseleni.Ifanele ukuthuthwa kwezinto ezibonakalayo ngendawo yokuqoqa ebanzi noma isitoreji esijulile.Indlela yokondla ilula, kodwa uma kuqhathaniswa nohlobo lokuphakela ingcindezi ngokwezokuthutha, kunemikhawulo ethile ekuphumeni kokuthutha kanye nebanga lokuthutha.
Ukucindezela okuhle nokubi kuhlanganiswe ukudlulisa:
Lolu hlelo luvame ukusetshenziswa ezinqubweni eziyinkimbinkimbi zesistimu yokudlulisa.Ukuhanjiswa kwe-pneumatic komlotha wempukane othintekayo kithi uthuthwa usuka kumqoqi wothuli uyiswe esiseleni, futhi inqubo ilula uma kuqhathaniswa.Imibandela yokudlulisa ayikhethekile.Kulula kakhulu, konga amandla futhi kunciphisa ukusetshenziswa ukusebenzisa indlela elula yokudlulisa, futhi kunengqondo.
Ukuhanjiswa kwe-positive pneumatic:
Uhlelo lunobuchwepheshe obuvuthiwe, izinqubo eziningi zobunjiniyela, ukusebenza kahle kokudlulisa, futhi ngeke lithintwe izinguquko ezimweni zokudlulisa.Ilungele ukuthutha okuhlakaziwe ukusuka endaweni eyodwa kuya ezindaweni eziningi.
Ifanele izinto zokuhamba ezinkulu, ezihamba amabanga amade.Bonke bangaphansi kwengcindezi enhle, futhi izinto ezisetshenziswayo zikhishwa kalula echwebeni lokukhipha.Indawo yokuvuza komoya ingatholakala kalula ukuze uthole ukwelashwa okufika ngesikhathi.
Ngenxa yokuthi igesi enothuli ayidluli ngaphakathi kwefeni, ukuguga kwefeni kuncane futhi nempilo yesevisi yinde.
Ngokusekelwe esingenisweni esingenhla, kungaphezulu mayelana nezici ze-fly ash ngokwayo, kanye nezidingo zokudlulisa izimo nokudlulisa ivolumu.Ngakho-ke, kunengqondo kakhulu ukukhetha i-positive pressure pneumatic conveying yokudlulisa umlotha wezimpukane.
Uhlolojikelele lwe-fly ash pneumatic conveying system
Eminyakeni yamuva, ekwelapheni umlotha wempukane ezitshalweni zamandla zokushiswa kwemfucuza, sivame ukusebenzisa amadivaysi okuhambisa umoya we-fly ash-pressure pneumatic.I-low-pressure pneumatic conveying ubuchwepheshe obuphambili nobusebenzayo obusebenzisa amandla egesi ukuthutha izinhlayiya eziqinile, futhi kunomlando weminyaka engaphezu kwe-100.Emlandweni wokuthuthukiswa kokudluliswa kwe-pneumatic yokucindezela okuphansi, ikakhulukazi emashumini eminyaka amuva nje, ubuchwepheshe obuphansi be-pneumatic conveying buye benza intuthuko ngokushesha.Umshini wokudlulisa umoya womfutho ophansi ngokuvamile wakhiwa isidlulisi, ivalvu yokuphakelayo, ivalvu yokukhipha umoya, ingxenye yokulawula okuzenzakalelayo kanye nepayipi elidlulisayo.
Isixazululo senkinga yokushiswa kwemfucuza komlotha wempukane sizothuthukisa ngempumelelo izinkinga zemvelo ezizungezile, futhi siyisinyathelo esikhulu esizuzisa izwe kanye nabantu.
