[I-XJY iKhokela ukuVeliswa okutsha]: Usetyenziso olugqwesileyo lwetekhnoloji yokususa uthuli lwengxowa kuqhushumbo lokususa uthuli lwerhasi yomlilo

Ngaphantsi kwemvelaphi yokuphumeza ukhuseleko lokusingqongileyo kunye nokugcinwa kwamandla ngendlela ejikelezayo, ukuphuculwa kobuchwephesha bokususa uthuli lwegesi eqhumayo kunye nokomeleza isiphumo sokususa uthuli lwegesi yokuqhuma kwegesi ibe yindlela engenakuthintelwa yokwakhiwa kwesimanje kunye nophuhliso lwamashishini anxulumeneyo. Ngokuqhubekayo ngokutsha kunye nokusetyenziswa kwetekhnoloji yokukhupha igesi yokuqhunyiswa kwegesi, itekhnoloji ye-dedusting kunye neyokucoca iye yaphuhliswa ukusuka ekugxothweni okumanzi ukuya kwi-dedusting eyomileyo (kubandakanywa ukuchithwa kwengxowa, ukuchithwa kwe-electrostatic, njl. njl.). Ngokusekelwe koku, ukuthatha iteknoloji yokususa uthuli lwengxowa njengomzekelo, ukuqala ngokujonga kwayo okuhambelanayo, ukusetyenziswa kweteknoloji yokususa uthuli lwengxowa kwi-blast furnace ukususwa kothuli lwegesi kuhlalutywa, kwaye iingxaki ezikhoyo zibekwe phambili.

1.Umbono jikelele weteknoloji yokususa uthuli lwengxowa

Ngaphantsi kwemvelaphi yokuphumeza ulwakhiwo lokusingqongileyo kunye nolwakhiwo lokugcina ubutyebi ngendlela ejikelezayo, iteknoloji yokususa uthuli lwengxowa iphumelele iziphumo ezithile zophuhliso, kunye neteknoloji yezixhobo zayo, iteknoloji yokulawula okuzenzekelayo, iinkonzo zemveliso, izincedisi zenkqubo, izinto ezikhethekileyo zokucoca ifayibha ziye. iphuculwe ngokwamanqanaba ahlukeneyo.

2.Indlela yokuSebenza yeTekhnoloji yokuSuswa uthuli kwiBlast Furnace yokuSuswa kwerhasi

2.1. Ukuqokelelwa kwezinto zokucoca kwingxowa yokucoca

Xa itekhnoloji yokucoca ingxowa isetyenziselwa ukuhlambulula kunye nokususa uthuli kwigesi yokuqhushumba yomlilo, izinto zokucoca kwingxowa yokucoca iya kuqokelela amasuntswana othuli ngesiphumo sokungqubana kwe-inertial, isiphumo se-electrostatic, isiphumo sokuhlola, isiphumo sokusasazwa kunye nesiphumo sokutsalwa kwe-gravity.

Umzekelo, xa amasuntswana amakhulu othuli kwisithando somlilo ephantsi kwesenzo sokuhamba komoya kwaye asondele kumgibe wefiber we-bag filter, ahamba ngokukhawuleza. Amasuntswana amakhulu aya kuphambuka kumzila wokuhamba komoya phantsi kwesenzo samandla e-inertia kwaye aqhubele phambili ecaleni kwendlela yokuqala, kwaye angqubane nemicu yokubambisa, eya kuba yomeleleyo phantsi kwefuthe lokucoca i-fiber filter. Ngoku amasuntswana othuli ayahluzwa. Kwangaxeshanye, xa i-airflow idlula kwizinto zokucoca i-bag filter, i-electrostatic effect yenziwa phantsi kwesenzo samandla okukhuhlana, okwenza ukuba amasuntswana othuli ahlawuliswe, kwaye amasuntswana othuli adsorbed kwaye abanjwe phantsi kwesenzo sokwahlukana okunokwenzeka. kunye namandla eCoulomb.

2.2. Ukuqokelelwa koMaleko wothuli kwi-Bag Dust Collector

Ngokuqhelekileyo, iingxowa zokucoca zengxowa yokucoca zenziwe ngeentsinga. Ngexesha lokucocwa kunye nokuhluzwa, amasuntswana othuli aya kwenza "into yokwenza ibhulorho" kwi-voids yokucoca inetha, eya kunciphisa ubungakanani bepore yomnatha wezinto zokucoca kwaye ngokuthe ngcembe yenze umaleko wothuli. Ngenxa yokuba i-diameter yamasuntswana othuli kumaleko othuli incinci kunedayamitha yefiber zezinto zokucoca ukuya kumkhamo othile, isihluzo kunye nokunqunyulwa komaleko wothuli kubonakala, kwaye isiphumo sokususa uthuli sesihluzo sengxowa siyaphuculwa.

2.3. Ukucocwa kunye nokususwa kothuli lwegesi yesithando somlilo ngesihluzo sengxowa. Ngokwesiqhelo, ubungakanani bamasuntswana osasazo lomsi kunye nothuli kwirhasi yesithando somlilo sisuka kwincinci ukuya enkulu. Ke ngoko, kwinkqubo yokucoca ingxowa, i-airflow equkethe amasuntswana othuli iya kudlula kwizinto zokucoca isihluzo sengxowa. Kule nkqubo, amasuntswana othuli amakhulu aya kushiywa kwisixhobo sokucoca okanye kumphezulu wesixhobo sokucoca umnatha ngomxhuzulane, ngelixa amasuntswana othuli amancinci (ngaphantsi kwelaphu lokucoca elingenanto) aya kunyanzelwa ukuba achaphazele, isikrini okanye ashiye ngaphakathi. itafile yezinto zokucoca. Umphezulu ushiywe kwindawo yelaphu lokucoca ngentshukumo yeBrownian. Ngoqokelelo oluqhubekayo lwamasuntswana othuli oluthinjwe zizixhobo zokucoca, umaleko wothuli uya kwenziwa kumphezulu webhegi yokucoca, kwaye ukuya kuthi ga kwinqanaba elithile, iya kuba "yi-membrane yesihluzi" yengxowa yokucoca ukuphucula ukucocwa kunye nothuli. isiphumo sokususa isihluzo sengxowa.

3.Ukusetyenziswa kweteknoloji yokususa ingxowa kwi-blast furnace gas dedusting

3.1. Isishwankathelo seSicelo

Inkqubo yokususwa kothuli lwengxowa iquka inkqubo yokususa uthuthu oluvuthela ngasemva, inkqubo yolawulo, inkqubo yemibhobho yerhasi ecocekileyo, inkqubo yobushushu ecocekileyo yegesi ecocekileyo, ukuthuthwa kothuthu kunye nenkqubo yokuthulula uthuthu, njl. njl. Isetyenziselwa ukuqonda ukucocwa. kunye nokususwa kothuli lwerhasi yesithando somlilo.

3.2. Ukusetyenziswa kweNkqubo yokuQokelelwa kothuli lwengxowa

3.2.1. Ukusetyenziswa kweNkqubo yokuCocwa koMfuthu ovuthelwe ngasemva

Kwinkqubo yokususa uthuthu lwengxowa, inkqubo yokususa uthuthu evuthelwe ngasemva inokwahlulwa ibe ngamacandelo amabini: inkqubo yokususa uthuthu evuthelwe ngasemva ecinezelekileyo kunye nenkqubo yokususa uthuthu evuthelwa ngasemva ngenitrogen. Inkqubo yokususa uthuthu evuthelwe ngasemva yimowudi yokucoca yangaphakathi. Xa irhasi enothuli iphumela ngaphandle ngengxowa yokucoca yesihluzo sengxowa, ukuhamba komoya kuya kutshintsha isalathiso phantsi kwesenzo senkqubo yokususa uthuthu oluvuthelwe ngasemva, ukuqonda ukuphuma komoya ukusuka ngaphandle ukuya ngaphakathi, ngaloo ndlela kufezekiswa injongo yokususa uthuli ngokuqokelela. yengxowa yokucoca. I-nitrogen pulse back-blown dust cleaning system kukuqukuqela irhasi equlethe amasuntswana othuli ukusuka ezantsi ukuya kumphezulu ongaphandle wengxowa yokucoca. Ngelixa ukomeleza indima yomaleko wothuli, ukuqokelelwa kothuli kumphezulu wangaphandle wengxowa yokucoca kunokucocwa ngokusebenzisa ivalve ye-pulse. Ukuze ukwandise indima yenkqubo yokucoca i-ash-back-blowing, uhlalutyo oluthile kufuneka lwenziwe ngokwemeko ethile kwisicelo sayo.

3.2.2. Ukusetyenziswa kweNkqubo yokuBonwa koxinzelelo oluhlukileyo

Kwinkqubo yesicelo sokucoca isikhwama, kubaluleke kakhulu ukuqinisekisa ukhuseleko kunye nokuzinza kwenkqubo yayo yokufumanisa uxinzelelo. Ngokuqhelekileyo, iindawo zokufumanisa umahluko woxinzelelo zisasazwa kakhulu kwi-gas inlet kunye nemibhobho yokuphuma kunye negumbi legesi elicocekileyo lomzimba webhokisi. Ubunzululwazi kunye nengqiqo yofakelo lwenkqubo isitshixo sokuqinisekisa ukuchaneka nokuchaneka kokubonwa kophawu loxinzelelo oluhlukileyo, kunye nokuchaneka kokuchaneka yindlela ephambili yokuphucula umgangatho wokugcinwa komqokeleli wothuli, kunye nendlela ebalulekileyo yokuphucula inkonzo. ubomi beengxowa zokucoca, ukuphucula umgangatho wenkqubo kunye nokunciphisa ukusetyenziswa kwamandla.

3.2.3. Ukusetyenziswa kweSixokelelwano soLawulo loBubushushu beGesi eSemi-ecocekileyo

Kwinkqubo yokunyibilika kwesithando somlilo kumashishini esinyithi kunye nentsimbi, igesi eveliswa zizixhobo zomlilo eziqhumayo iya kuba "yigesi ecocekileyo ecocekileyo" phantsi kwesenzo sokuhlanjululwa komxhuzulane kunye nokususwa kothuli. Kwangaxeshanye, irhasi ecocekileyo ingena kwisingxobo sokucoca ngevalve engaboniyo, ivelufa yebhabhathane lomqokeleli wothuli kunye nombhobho werhasi ococekileyo ukuze ususwe uthuli. Ngokuqhelekileyo, xa igesi ecocekileyo ingena kwi-tube yokuqokelela uthuli, ukushisa kwegesi kuya kutshintsha ukuya kwinqanaba elithile, oko kukuthi, ukufudumeza. Ngokunyuka kweqondo lokushisa, ukuhamba komoya kuya kutshabalalisa isikhwama sokucoca kumqokeleli wothuli kwaye sitshise isikhwama sokucoca. Ngoko ke, ukuze kuqinisekiswe ukhuseleko lweqondo lokushisa, kuyimfuneko ukufakela inkqubo yokulawula ubushushu begesi ecocekileyo.

3.2.4. Ezinye iziCwangciso zokuSebenza

Ukuze kuqinisekiswe umdlalo opheleleyo wendima yokucoca ingxowa kunye nokunciphisa ukusetyenziswa kwamandla ekusebenzeni. Kwinkqubo yesicelo, kuyimfuneko ukuba ukhethe ngokwesayensi i-valve yebhokisi yokuqokelela uthuli ukuqinisekisa ukhuseleko kunye nokuqina kwenkqubo kwaye ugweme ukuvuza kwegesi kwinkqubo yokususa uthuli. Ngokuqhelekileyo, xa uxinzelelo lwenkqubo womnatha utshintsho kunye neziphumo ezibi kwiivalvu butterfly, ipleyiti ethe ngqo uthuli butterfly valves okanye ngofakelo imingxunya yokucoca uthuli ingasetyenziselwa ukomeleza iivalve butterfly.

4.Amagqabantshintshi okuqukumbela

Kwimizi-mveliso yokunyibilikisa, kubaluleke kakhulu ukuphucula izinga lokusetyenziswa kwemithombo yerhasi yesithando somlilo, ukunciphisa ungcoliseko lokusingqongileyo kwigesi eqhumayo, kuphuculwe ukusebenza kakuhle kwezoqoqosho kumashishini, kunye nokukhuthaza uphuhliso oluzinzileyo lwamashishini.
