Mumufananidzo mukuru wekugadzirwa kwemaindasitiri, pane zvinhu zvidiki zvinoita sezviri kuita mabasa akakosha chinyararire. Mushonga wekubvisa simbi yesilicon carbide "unoshanda segamba riri kuseri kwezviitiko" - unovanda mushongwe yekubvisa simbi yemagetsi nemafekitori esimbi, uchichenesa gasi remagetsi remaindasitiri zuva nezuva, uchibvisa sulfur dioxide inokuvadza usati wabuda. Chii chakakosha chemuchina uyu wakagadzirwa nezvinhu zvesilicon carbide?
1. Sei silicon carbide ichishandiswa? 'Mapfupa akaomarara' ari muzvinhu izvi
Kunzwisisa zvakanakira zvemaburi ekubvisa silicon carbide, tinofanira kutanga ne "bumbiro" ravo. Silicon carbide chinhu chisina kugadzirwa chakagadzirwa nenzira yekugadzira, chine maatomu akabatanidzwa nezvisungo zvakasimba zve covalent kuti zvigadzire chimiro chakasimba chakafanana nedhaimani. Chimiro ichi chinopa "masimba makuru" matatu:
Inodzivirira ngura: Gasi rinoyerera mumaindasitiri rinosanganiswa nezvinhu zvinoparadza zvakaita seacid mhute ne limestone slurry, uye maburi esimbi akajairwa achakurumidza kusviba uye kuzara nemaburi. Silicon carbide inodzivirira acid nealkali zvakanyanya kupfuura simbi, uye inogona kuchengetedza chimiro chayo kunyangwe mushure mekunyudzwa kwenguva refu munzvimbo dzine ngura zvakanyanya.
Inogona kutsungirira tembiricha yakakwira: Tembiricha yemhepo inoyerera mukati me desulfurization tower inowanzosvika mazana emadhigirii Celsius, uye dzimwe nguva panogona kuve nekusiyana kwakanyanya kwetembiricha nekuda kwekutanga uye kudzimwa kwemidziyo. Kugadzikana kwekupisa kwesilicon carbide kwakasimba kwazvo, uye hazvisi nyore kutsemuka kunyangwe paine kuputika kwekupisa kwakakwira ipapo ipapo. Ichiri yakavimbika mumamiriro ekunze ekupisa kwakakwira zvakanyanya.
Inogona kutsungirira kusakara: Kana slurry inoyerera nekukurumidza ichipfuura nemumuromo, icharamba ichiparadza rusvingo rwemukati. Kuomarara kwesilicon carbide kwakafanana nedhaimani, uye inogona kuramba nyore nyore kusakara kwerudzi urwu. Hupenyu hwayo hwekushanda hwakapetwa kakawanda kupfuura hwepurasitiki kana simbi.
2, Kwete chete 'inogara kwenguva refu', asiwo 'inosimudzira' yekushanda zvakanaka kwe desulfurization
Kukosha kwema nozzles e silicon carbide desulfurization kunopfuura "hupenyu hurefu". Magadzirirwo awo anovanza chakavanzika: nzira dzemukati dzinotenderera dzinobvumira slurry ye desulfurization kuti irambe ichisangana uye ichisangana mukuyerera, pakupedzisira ichiita madonhwe akanaka uye akafanana - nzvimbo yakakura pakati pemadonhwe aya negasi re flue, ndiko kuwedzera kushanda kwe sulfur dioxide.
Chinonyanya kukosha ndechekuti haivharike nyore. Zvidimbu zvidiki zvinosanganiswa mumatope emaindasitiri, uye nzira dzakamanikana dzema nozzles akajairwa dzinovharika zviri nyore, zvichikonzera kupfapfaidza kusina kuenzana uye kudzikira kwekushanda kwe desulfurization. Dhizaini ye flow channel ye silicon carbide nozzle yakakura, ichibvumira zvidimbu kuti zvipfuure zvakanaka, zvichideredza zvikuru nguva yekushanda uye kugadziriswa kunokonzerwa nekuvharika.
3, 'Sarudzo inokosha' pasi pemitemo yekuchengetedzwa kwezvakatipoteredza
Nekuda kwemitemo yezvakatipoteredza iri kuramba ichioma, mabhizinesi ane zvinodiwa zvakanyanya zvemidziyo yekubvisa sarufa. Semuenzaniso, muganho wehuwandu hwesarufa dioxide mugasi remvura rinoburitswa nemagetsi wakasimbiswa zvakanyanya. Izvi zvinoreva kuti sisitimu yekubvisa sarufa inofanira kushanda zvakanaka uye yakagadzikana - uye mashandiro emuromo wemuromo anokanganisa zvakananga mhedzisiro yekupedzisira yekuchenesa.
Kunyangwe mutengo wekutanga wekutenga ma nozzles e silicon carbide desulfurization wakakwira kupfuura we nozzles dzakajairika, chaizvoizvo anodhura zvishoma munguva refu. Hupenyu hwayo hwekushanda hwakareba kakawanda kupfuura hwe nozzles dzepurasitiki, izvo zvinogona kuderedza zvakanyanya kurasikirwa kwekutsiva uye kurasikirwa nenguva yekusashanda. Kune makambani ari kutsvaga kugadzirwa kwakasimba, hunhu hwe "kudyara kamwe chete, kusava nehanya kwenguva refu" hunonyanya kukosha.
4, Kwete kungobvisa sulfurization chete, asi mafomu emangwana anoonekwa
Pamusoro pekugadzirisa gasi remagetsi emumaindasitiri, mukana wezvinhu zvesilicon carbide uri kubuda muminda yakawanda. Kusagona kwayo kupisa kwakanyanya uye kuramba kwayo mwaranzi kunoita kuti ionekwe munzvimbo dzepamusoro dzakadai sesimba renyukireya nendege; Muindasitiri itsva yesimba, inoshandiswawo mumidziyo inopisa kupisa yepamusoro yezvinhu zvebhatiri re lithium. Semushonga wekubvisa sulfurization, inoramba iri chikamu chakakosha chekutonga kwezvakatipoteredza pari zvino.
Ichi 'chikamu chidiki' chakavanzwa mushongwe yekubvisa sarufa chaizvoizvo ibhiriji pakati pebudiriro yemaindasitiri nekuchengetedzwa kwezvakatipoteredza. Chinoshandisa huchenjeri hwesainzi yezvinhu kuti zvikwanisike kuti kugadzirwa kwemaindasitiri kuenderane nematenga ebhuruu nemakore machena - zvichida kududzirwa kwakanakisa kwetekinoroji inodzivirira nharaunda.
