[I-XJY Leads Innovation]: Ukusetshenziswa okuhle kakhulu kobuchwepheshe bokususa uthuli lwesikhwama ekususeni uthuli lwegesi yesithando somlilo

Ngaphansi kwesizinda sokuqalisa ukuvikela imvelo nokonga amandla ngendlela eyindilinga, ukuthuthukiswa kobuchwepheshe bokususa uthuli lwegesi yesithando somlilo esiqhumayo kanye nokuqinisa umphumela wokususwa kothuli lwegesi yesithando somlilo sekuqhuma sekuphenduke inkambiso engenakugwenywa yokwakhiwa kwesimanje nokuthuthukiswa kwezimboni ezihlobene. Ngokusungulwa okuqhubekayo kanye nokusetshenziswa kobuchwepheshe bokukhipha igesi ye-blast furnace, ubuchwepheshe bayo bokukhipha kanye nokuhlanzwa buthuthukile kusukela ekukhipheni okumanzi kuya ekukhipheni okomile (okuhlanganisa ukuchithwa kwesikhwama, ukuchithwa kwe-electrostatic, njll.). Ngokusekelwe kulokhu, ukuthatha ubuchwepheshe bokukhipha uthuli lwezikhwama njengesibonelo, kuqale ngokubuka kwayo konke okuhlobene, ukusetshenziswa kobuchwepheshe bokukhipha uthuli lwesikhwama ekukhipheni uthuli lwesithando somlilo esiqhumayo kuyahlaziywa, bese kubekwa phambili izinkinga ezikhona.

1.Ukubuka konke kobuchwepheshe bokukhipha uthuli lwesikhwama

Ngaphansi kwesizinda sokuqalisa ukwakhiwa kokuvikela imvelo kanye nokwakhiwa okonga izinsiza ngendlela eyindilinga, ubuchwepheshe bokususa uthuli lwesikhwama buzuze imiphumela ethile yentuthuko, kanye nobuchwepheshe bayo bemishini, ubuchwepheshe bokulawula okuzenzakalelayo, izinsizakalo zomkhiqizo, izesekeli zesistimu, izinto ezikhethekile zokuhlunga i-fiber ithuthukiswe ngamazinga ahlukahlukene.

2.I-Application Mechanism yesikhwama Sokususa Uthuli Ukususwa Kwezintuli Ze-Blast Furnace

2.1. Ukuqoqwa kwezinto zokuhlunga zesihlungi sesikhwama

Lapho ubuchwepheshe bokuhlunga isikhwama busetshenziselwa ukuhlanza nokususa uthuli kugesi yesithando somlilo, izinto zokuhlunga kusihlungi sesikhwama zizoqoqa izinhlayiya zothuli ngomphumela wokungqubuzana okungenasici, umphumela we-electrostatic, umphumela wokuhlola, umphumela wokusabalalisa kanye nomphumela wokudilizwa kwe-gravity.

Isibonelo, lapho izinhlayiya ezinkudlwana zothuli esithandweni somlilo zingaphansi kwesenzo sokugeleza komoya futhi ziseduze ne-fiber trap yesihlungi sesikhwama, zigeleza ngokushesha. Izinhlayiya ezinkudlwana zizochezuka kumzila wokugeleza komoya ngaphansi kwesenzo samandla e-inetia futhi ziqhubekele phambili ngomzila wokuqala, futhi zingqubuzane nemicu yokucupha, ezoqina ngaphansi komphumela wokubamba isihlungi sefayibha. Manje izinhlayiya zothuli ziyahlungwa. Ngesikhathi esifanayo, lapho ukugeleza komoya kudlula ezintweni zokuhlunga zesihlungi sesikhwama, umphumela we-electrostatic kwakheka ngaphansi kwesenzo samandla okungqubuzana, okwenza izinhlayiya zothuli zishajwe, futhi izinhlayiya zothuli ziyakhangiswa futhi zivaleleke ngaphansi kwesenzo somehluko ongaba khona. kanye ne-Coulomb force.

2.2. Ukuqoqwa Kwe-Dust Layer ku-Bag Dust Collector

Imvamisa, izikhwama zokuhlunga zesisefo sesikhwama zenziwe ngemicu. Ngesikhathi sokuhlanza nokuhlunga, izinhlayiya zothuli zizokwakha "isenzakalo sokuvala ibhuloho" ku-voids yenethi yezinto zokuhlunga, okuzonciphisa usayizi we-pore wenethi yezinto zokuhlunga futhi kancane kancane yakhe ungqimba lothuli. Ngenxa yokuthi ububanzi bezinhlayiya zothuli kungqimba lothuli buncane kunobubanzi bemicu yezinto zokuhlunga ngokwezinga elithile, isihlungi nokunqamula ungqimba lothuli kuyavela, futhi umphumela wokukhipha uthuli wesihlungi sesikhwama uyathuthukiswa.

2.3. Ukuhlanzwa nokususwa kothuli lwegesi yesithando somlilo ngesihlungi sesikhwama. Ngokuvamile, ukusatshalaliswa kosayizi wezinhlayiyana zentuthu nothuli kugesi yesithando somlilo kusuka kokuncane kuye kokukhulu. Ngakho-ke, ohlelweni lokusebenza kwesihlungi sesikhwama, ukugeleza komoya okuqukethe izinhlayiya zothuli kuzodlula ezintweni zokuhlunga zesihlungi sesikhwama. Kule nqubo, izinhlayiya zothuli ezinkulu zizoshiywa endaweni yokuhlunga noma phezu kwenethi yezinto zokuhlunga ngamandla adonsela phansi, kuyilapho izinhlayiya zothuli ezincane (ezingaphansi kwendwangu engenalutho) zizophoqeleka ukuthi zithinte, zibuke noma ziphume phakathi. ithebula lempahla yokuhlunga. Ingaphezulu lishiywe esikhaleni sendwangu yokuhlunga ngokunyakaza kwe-Brownian. Ngokuqoqwa okuqhubekayo kwezinhlayiya zothuli ezithathwe izinto zokuhlunga, kuzokwakhiwa ungqimba lothuli phezu kwesikhwama sokuhlunga, futhi ngezinga elithile, kuzoba "ulwelwesi lwesihlungi" lwesikhwama sokuhlunga ukuthuthukisa ukuhlanzeka nothuli. umphumela wokususwa kwesihlungi sesikhwama.

3.Ukusetshenziswa kobuchwepheshe bokukhipha isikhwama ekuqhumeni kwegesi esithandweni somlilo

3.1. Uhlolojikelele Lokusebenza

Uhlelo lokususa uthuli lwezikhwama ikakhulukazi luhlanganisa uhlelo lokususa umlotha oluvuthela emuva, uhlelo lokulawula, uhlelo lwepayipi legesi elihlanzekile kancane, isistimu yokuphepha kwegesi ehlanzekile, ukuthutha umlotha kanye nohlelo lokuthulula umlotha, njll. Lusetshenziselwa ukuqaphela ukuhlanzwa. kanye nokususwa kothuli lwegesi ye-blast furnace.

3.2. Ukusetshenziswa kwe-Bag Dust Collection System

3.2.1. Ukusetshenziswa Kwesistimu Yokuhlanza Imfucumfucu

Ohlelweni lokususa uthuli lwezikhwama, uhlelo lokususa umlotha oluphehlwa ngemuva lungahlukaniswa izigaba ezimbili: uhlelo lokususa umlotha oluphephezelwa ngemuva kanye nesistimu yokususa umlotha eshaywa nge-nitrogen. Isistimu yokususa umlotha efutha ingcindezi emuva iyimodi yokuhlunga yangaphakathi. Lapho igesi enothuli igelezela ngaphandle ngesikhwama sokuhlunga sesihlungi sesikhwama, ukugeleza komoya kuzoshintsha isiqondiso ngaphansi kwesenzo sesistimu yokususa umlotha epheshulwe ngemuva, ibone ukugeleza komoya kusuka ngaphandle kuya ngaphakathi, ngaleyo ndlela kufezeke inhloso yokususa uthuli ngeqoqo. wesikhwama sokuhlunga. Uhlelo lokuhlanza uthuli lwe-nitrogen pulse luwukugeleza igesi equkethe izinhlayiya zothuli ukusuka phansi ukuya endaweni engaphandle yesikhwama sokuhlunga. Ngenkathi kuqinisa indima yongqimba lothuli, ukunqwabelana kothuli endaweni engaphandle yesikhwama sokuhlunga kungahlanzwa ngokusebenzisa i-valve ye-pulse. Ukuze kwandiswe indima yesistimu yokuhlanza umlotha obuya emuva, ukuhlaziya okuqondile kufanele kwenziwe ngokuvumelana nesimo esithile ekusetshenzisweni kwayo.

3.2.2. Ukusetshenziswa Kwesistimu Yokuthola Ingcindezi Ehlukile

Enqubweni yokufaka isicelo sesihlungi sesikhwama, kubaluleke kakhulu ukuqinisekisa ukuphepha nokuzinza kwesistimu yayo yokuthola ingcindezi ehlukile. Imvamisa, izindawo zokuthola umehluko wengcindezi zitholakala kakhulu kumapayipi okufaka igesi nokuphuma kanye negumbi legesi elihlanzekile lebhokisi lebhokisi. Isayensi nokuhluzeka kokufakwa kwesistimu kuyisihluthulelo sokuqinisekisa ukunemba nokunemba kokutholwa kwesignali yengcindezi ehlukile, futhi ukunemba kokutholwa kuyindlela eyinhloko yokuthuthukisa ikhwalithi yokugcinwa kokuqoqa uthuli, kanye nendlela ebalulekile yokuthuthukisa isevisi. impilo yezikhwama zokuhlunga, thuthukisa ikhwalithi yesistimu futhi unciphise ukusetshenziswa kwamandla.

3.2.3. Ukusetshenziswa Kohlelo Lokulawula Ukushisa Kwegesi Ehlanzekile Ngaphakathi

Enqubweni yokuncibilikiswa kwesithando somlilo ezinkampanini zensimbi nezensimbi, igesi ekhiqizwa imishini yesithando somlilo izoba "igesi ehlanzekile kancane" ngaphansi kwesenzo sokuhlanzwa kwamandla adonsela phansi kanye nokususa uthuli. Ngesikhathi esifanayo, igesi ehlanzekile ingena esikhwameni sokuhlunga isikhwama ngevalvu eyimpumputhe, ivalve uvemvane lomqoqi wothuli kanye nepayipi legesi ehlanzekile kancane ukuze kukhishwe uthuli. Ngokuvamile, lapho i-semi-clean gas ingena ku-tube yokuqoqa uthuli, izinga lokushisa legesi lizoshintsha ngezinga elithile, okungukuthi, ukushisa. Ngokukhuphuka kwezinga lokushisa, ukugeleza komoya kuzobhubhisa isikhwama sokuhlunga esiqoqweni sothuli futhi kushise isikhwama sokuhlunga. Ngakho-ke, ukuze kuqinisekiswe ukuphepha kwezinga lokushisa, kuyadingeka ukufaka uhlelo lokulawula ukushisa kwegesi elihlanzekile semi-clean lokulawula izinga lokushisa.

3.2.4. Amanye Amasu Okusebenza

Ukuze kuqinisekiswe ukudlala okugcwele kwendima yesihlungi sesikhwama nokunciphisa ukusetshenziswa kwamandla ekusebenzeni. Enqubweni yokufaka isicelo, kuyadingeka ukukhetha ngokwesayensi i-valve yebhokisi lokuqoqa uthuli ukuze kuqinisekiswe ukuphepha nokuqina kwesistimu futhi kugwenywe ukuvuza kwegesi ngesikhathi sokususwa kothuli. Ngokuvamile, lapho ukucindezela kwenethiwekhi yesistimu kushintsha futhi kunemiphumela emibi kuma-valve ovemvane, ama-valve e-butterfly othuli lwepuleti eqondile noma ngokufaka izimbobo zokususa uthuli angasetshenziswa ukuqinisa ama-valve ovemvane.

4.Amazwi okuphetha

Ekuncibilikisweni kwezimboni, kubaluleke kakhulu ukwenza ngcono izinga lokusetshenziswa kwemithombo yegesi yesithando somlilo, ukunciphisa ukungcoliswa kwemvelo kwegesi yesithando somlilo, ukuthuthukisa ukusebenza kahle kwezomnotho kwamabhizinisi, kanye nokukhuthaza ukuthuthukiswa kokuncintisana okusimeme kwamabhizinisi.
