Isilo Sokugcina Usimende Nomlotha WaseFly: Ukuhamba Komoya Nokuklanywa Kokungenisa Umoya
I-silo yokugcina usimende nomlotha wendiza iwuhlelo lomoya, hhayi umgqomo: umlotha wendiza (impushana ecwebezelayo ene-pozzolanic) nosimende kufuthwa kungene ngomzila wokugcwalisa, kugcinwe kuketshezi ngezindawo zokungenisa umoya, bese kukhishwa ngomgudu wokuphuma okulinganiselwe, kanti wonke umjikelezo ulawulwa ukulawulwa komswakama nokuhambisana nokukhishwa kothuli. Ukuminyana okuphansi komlotha wendiza nokuhamba komoya okuphezulu kwenza ukuhlunga komoya nokulungisa ukungenisa umoya kube nzima kakhulu kunosimende, kuyilapho ukungena komswakama kuphendula noma iyiphi into ibe yinto eqinile eyomileyo ebhubhisa ukugeleza. I-silo yakhiwe ngokuya ngezici zokugeleza kwento, igobolondo elivaliwe eliboshiwe, isiphefumuli esihlungiwe, kanye nokuhlolwa kwesakhiwo ngokuya ngesisekelo somoya nokuzamazama komhlaba wendawo ukuze impushana ihambe ngokuthembekile nangokuhlanzekile.
I-Fly ash evela esiteshini samandla kanye nosimende ovela emshinini wokugaya kubukeka kufana elolini kodwa kuziphatha ngendlela ehlukile ku-silo. Kokubili iyimpushana ecwebezelayo egcwala futhi yakhe amabhuloho; i-fly ash ilula, idonsa umoya kakhulu futhi ishesha ukuqina uma ibona amanzi. I-silo yokugcina esebenza noma iyiphi yalezi zinto kumele ibe indawo elawulwayo yomoya — ukugcwalisa, ukufaka umoya, ukukhipha nokukhipha umoya — kungenjalo iyagcwala udaka, ikhipha uthuli, futhi ivale isitshalo esingezansi. Abahloli abathatha i-silo kasimende/ye-fly ash njenge-hopper emile bathenga ukuvaleka. Le ndatshana ihlanganisa ukuklanywa komoya nokufaka umoya okugcina lezi mpushana zihamba futhi zihambisana nemithetho.
Ukugcwalisa Ngomoya Kuyindlela Yokulethwa Ezenzakalelayo Yazo Zombili Izinto
Usimende nomlotha waseFly kufika ngeloli elikhulu noma ngesitimela futhi kufuthwa kungene esilweni ngomoya, ngakho ipayipi lokugcwalisa, ukuphuma komoya esilweni kanye nesivinini sangaphakathi kumele kuklanywe ndawonye ukuze kugwenywe izindlwana eziminyene nokulahleka kothuli. Ukugcwalisa kuwukugeleza komoya nento eqinile, hhayi ukuthela.
· Ipayipi lokugcwalisa nendawo yokungena. Ilinganiswe ngenani lokulethwa futhi ifakwe ingqinamba engagugi lapho umfudlana ujika khona; indawo yokungena ibeka umfudlana ukuze kugwenywe ukuhuzuka kodonga.
· Ukuphuma komoya ngesikhathi sokugcwalisa. Umoya okhishwayo uphuma ngembobo yokuhlunga; uma imbobo incane kakhulu isilo siba nengcindezi futhi uthuli luphuma kuzo zonke izivalo.
· Ukusatshalaliswa kwangaphakathi. Umfudlana ongenayo uqondiswa ukuze ungabi nomthelela futhi ungagugudli udonga oluphambene noma udale ikhoni eligcwele endaweni elizodala umgodi kamuva.
Ngenxa yokuthi umlotha wendiza uthwala umoya omningi ogxilile kunosimende, umfudlana wawo wokugcwalisa udinga indawo ebanzi yokuphuma komoya kanye nendawo yokuphuma ehlelwe ingxenye encane kakhulu.
Amaphedi Okungenisa Umoya Nezindawo Zokuhambisa Uketshezi Zigcina Uphawuda Ugeleza
Ukuthembeka kokukhipha kuvela ekugcineni i-powder i-fluidized ku-cone, ngakho ama-aeration pads noma i-fluidizing bottom kucaciswa ngokuhambisana ne-angle of repose kanye ne-permeability yento, hhayi ukungezwa njengomcabango wamuva. Ngaphandle kwe-aeration, ama-powders amahle akha ama-arches aqinile futhi ayeke.
Isici | Usimende | I-Fly ash |
Ukuminyana kwenqwaba | Phezulu (~1,400 kg/m³) | Phansi (~700–1,000 kg/m³) |
Ukuthambekela kokugeleza | Amabhuloho, izikhukhula | Amabhuloho, izikhukhula, umoya omningi |
Isidingo sokungenisa umoya | Ama-pads e-cone, alinganiselayo | Ama-pads e-cone, alungiselelwe ukukhanya |
Isihlungi somoya | Isihlungi esihle esijwayelekile | Isihlungi esihle kakhulu, indawo enkulu |
Ukungenisa umoya kusebenzisa umoya onengcindezi ephansi (imvamisa isiphephetha somoya esincane) ngokusebenzisa amaphedi anezimbobo ku-hopper; umoya wehlisa ukungqubuzana kodonga futhi uvumela i-valve ejikelezayo noma isikulufu ukukala umfudlana ozinzile oya ku-batcher noma emugqeni olandelayo womoya.
Ukulawula Umswakama Kuwumehluko Phakathi Kokugeleza Nokuqina
Ukwehluleka okukhulu kanye kokugcina usimende nomlotha wendiza ngamanzi — umswakama wenza impushana ibe yisethi eqinile okungekho moya ongayinyakazisa, ngakho ukuvalwa, ukomiswa komoya kanye nokuqina kophahla kuklanywe njengokubalulekile ekuhambeni. Zombili lezi zinto ziyi-hydraulic noma i-pozzolanic; zilapha ngamanzi.
· Igobolondo elivaliwe nophahla. Ama-silo aboshiwe asebenzisa amajoyinti avaliwe nemigwaqo yabantu; uphahla lwekhoni lukhipha isimo sezulu futhi lunciphisa indawo yomoya oswakeme.
· Ukomiswa komoya. Lapho umswakama uphezulu, isiphefumuli sifaka i-dessicant noma i-silo igcinwa ngaphansi kwengubo yomoya owomile omncane ukuze kuvinjwe ukungena komswakama ngesikhathi sokudonsa.
· Ayikho indlela yokujiya. Ingaphezulu langaphakathi ligcinwa lifudumele noma lifakwe i-insulation ukuze umoya oswakeme ungajiyi odongeni bese ugijima ungene kukhoni.
Ukuqedwa kwangaphakathi kwe-enamel ye-GFS kuyasiza lapha ngoba isikhumba sayo esibushelelezi, esingangenisi (Ra < 0.8 µm) asibambi izinhlayiya zokuqala eziswakeme eziqala isethi.
Ukukhishwa Kothuli Nokuhambisana Nemvelo Esilweni
Konke ukugcwaliswa nokukhipha kuhambisa uthuli olucolekile emoyeni we-silo, futhi imikhawulo yokukhishwa kwentuthu yenza i-filter vent kanye namajoyinti avaliwe kube yinto edingekayo yokuhambisana nomthetho, hhayi into ongayikhetha. I-Fly ash ikakhulukazi iyingxenye yothuli olucolekile okufanele kwaziswe ngayo.
· Ukusebenza kwe-filter vent. Ibamba izingxenyana ezicolekile zikasimende/fly-ash endaweni yokuphefumula; ukuhlanza nge-reverse-pulse kugcina indawo yokuhlunga ihamba futhi ukwehla kwengcindezi kwaziwe.
· Amathuluzi okulinganisa izinga nengcindezi. Isibonisi sezinga eliphezulu sivimbela ukugcwala ngokweqile; isikali sokuhluka kwengcindezi sibonisa ukuthi i-vent ayivalwanga.
· Ukuvimbela kwesibili nokugcina indawo ihlanzekile. Amathreyi okuchitheka kanye nezindawo zokudlulisa ezivaliwe zinciphisa uthuli olubalekayo endaweni yokuxhuma iloli nasekukhipheni.
Ukuhambisana nomthetho kubhalwa ngokusebenza okulinganiselwe kwe-vent kanye nokuqapha okubonisa ukuthi ihlala ingaphakathi kwemikhawulo phakathi nomjikelezo wokusebenza.
Ukuhlolwa Kwesakhiwo Nokuzamazama Komhlaba Kwe-Powder Tower Ezacile
I-silo likasimende/i-fly-ash iyisakhiwo eside, esivame ukuba nomphezulu okhanyayo lapho izimo zomoya nokuzamazama komhlaba zilawula khona uma ingenalutho, ngakho ukhwephezulu, izibophezeleli kanye nesisekelo kuhlolwa ngokwesisekelo sendawo njengephakethe elilodwa. Umpufuli ogciniwe wengeza umfutho we-Janssen ovundlile odongeni ngesikhathi sokukhipha.
· Umoya (ASCE 7 / EN 1991-1-4). Ukugoqa nokugingqika uma kungenalutho futhi kugcwele; imibhoshongo emide ilawulwa umoya.
· Ukuzamazama komhlaba (ASCE 7 / EN 1998-4). I-inertia kukhwephezulu kanye nesisindo esigciniwe; ukukhushulwa kanye nokugawulwa kwezibophezeleli kanye ne-ring beam.
· Isisekelo. I-ring beam noma i-raft ethwala ukuqondile, ukugingqika kanye nokukhushulwa; ukuthwala kwenhlabathi kunquma isimo.
Umkhiqizi uhlanganisa uhlelo lwamaphaneli/ama-stiffener namandla okuxhumana e-anchor nesisekelo ukuze uhlelo lwe-powder lube ngokuphelele ngokwesakhiwo.
