A fanFurming fan licandelo elikhethekileyo lokungenisa umoya kwimizi-mveliso eyenzelwe ukusebenza kwiinkqubo ze-flue gas desulfurization (FGD). Aba balandeli babaluleke kakhulu ekugcineni uxinzelelo olubi okanye olulungileyo kwi-scrubbers, ukuqinisekisa ukususwa ngokufanelekileyo kwe-sulfure dioxide (SO₂) kwiigesi zokukhupha. Idizayinelwe ukumelana neendawo ezinobungozi kakhulu, ubushushu obuphezulu, kunye ne-abrasive, i-fan ye-desulfurization ethembekileyo idibanisa ulwakhiwo oluqinileyo-njengensimbi engenasici okanye i-FRP-kunye nokusebenza kwe-aerodynamic echanekileyo. Ukukhetha umenzi ofanelekileyo kuqinisekisa ukuthotyelwa kwemimiselo yokusingqongileyo ngelixa unciphisa ixesha lokusebenza kunye neendleko zokugcina.
Yintoni iFani yeDesulfurization kwaye kutheni ibalulekile?
Kumashishini anzima afana nokuvelisa amandla, isinyithi, kunye nokulungiswa kweekhemikhali, ukutshiswa kwamafutha efosili kukhupha i-sulphur dioxide, eyona nto inegalelo kwimvula eneasidi kunye nongcoliseko lomoya. Ukunciphisa oku, amaziko afakela iinkqubo zeFlue Gas Desulfurization (FGD). I fanFurming fan isebenza njengentliziyo yale nkqubo, inikezela ngentloko yoxinzelelo oluyimfuneko ukuhambisa igesi yombane ngokusebenzisa izigaba ezahlukeneyo zonyango, kubandakanywa i-absorbers, i-mist eliminators, kunye nabatshintshisi bobushushu.
Ngokungafaniyo nabalandeli bemveliso eqhelekileyo, abalandeli be-desulfurization bajongana neemeko zokusebenza ezigqithisileyo. Umjelo werhasi uhlala uqulathe ukufuma, iikhompawundi ezineasidi, kunye nenye into. Ngenxa yoko, ezi feni kufuneka zakhiwe ngezinto ezinganyangekiyo kwi-corrosion kwaye ziyilelwe ukuthembeka okuphezulu. Ukusilela kwifeni ye-desulfurization kunokukhokelela ekuvalweni kwezityalo kwangoko, izohlwayo zolawulo, kunye neengozi ezibalulekileyo zendalo.
Imisebenzi engundoqo kwiiNkqubo zeFGD
- Ugcino loxinzelelo: Ukoyisa ukuchasana kwi-ductwork kunye ne-scrubber towers ukuqinisekisa ukuhamba kwegesi okuhambelanayo.
- Ukuxhathisa ukonakala: Ukumelana ne-condensates ene-acidic eyenziwe ngexesha lokupholisa kunye nokucocwa kwegesi yombane.
- Ukuphatha ubushushu: Isebenza ngokufanelekileyo kwiintlobo ezahlukeneyo zamaqondo obushushu, ukusuka kwirhasi ekrwada eshushu ukuya epholileyo, ephathwayo.
- Ukusebenza kakuhle kwamandla: Ukunciphisa ukusetyenziswa kwamandla ngelixa uhambisa umthamo womoya ofunekayo (CFM) kunye noxinzelelo lwe-static.
Imingeni yobuGcisa kwiNdawo yokuNxilwa kwesulfurization
Ukuyila ifeni yezicelo ze-desulfurization kufuna ubuchwephesha bobunjineli obunzulu. Imo engqongileyo ngaphakathi kwenkqubo ye-FGD yenye yezona zinto zihlaselayo kwishishini lokusetyenzwa. Iinjineli kufuneka ziphendule ngezinto ezininzi zokuthotywa ngaxeshanye.
Ukonakala kunye noKuwohloka kwezinto
Owona mceli mngeni mkhulu kukudleka kweekhemikhali. Irhasi yomkhuhlane iqulethe i-sulphur trioxide (SO₃), ethi idibane nomphunga wamanzi yenze inkungu ye-sulfuric acid. Le asidi ijiya kwii-blades zefeni kunye nezindlu, ezikhokelela ekunciphiseni ngokukhawuleza kwezinto kunye nokusilela kwesakhiwo ukuba izixhobo ezingachanekanga zisetyenziswa. Izinto eziqhelekileyo ziquka:
- Intsimbi engatyiwa (316L/2205): Inika ukuchasana okugqwesileyo kwikloridi kunye neendawo ezineasidi.
- IPlastiki eFayibha Eyongeziweyo (FRP): Ikhaphukhaphu kwaye ixhathise kakhulu ekuhlaselweni kweekhemikhali, ilungele iindawo ezisezantsi zobushushu.
- I-Nickel Alloys (C-276): Isetyenziswe kwiimeko ezigqithisileyo apho isinyithi esisemgangathweni esingenasici sihluleka.
- Intsimbi enerabha: Ibonelela ngomqobo okhuselayo ngokuchasene ne-abrasion kunye ne-corrosion.
I-Abrasion kunye ne-Pact Impact
Nasemva kokususwa kothuli lwangaphambili, irhasi yeflue iqulethe intwana encinci. Ngezantya eziphezulu, la masuntswana akhukulisa ii-fan blades, ngakumbi kwiindawo eziphambili. Olu khukuliseko luguqula iphrofayili ye-aerodynamic yee-blades, ukunciphisa ukusebenza kakuhle kunye nokubangela ukungalingani. Iifeni ze-desulfurization ezikumgangatho ophezulu zibonisa imiphetho eyomeleziweyo okanye iingubo ezikhethekileyo zokunciphisa ukunxiba.
Uxinzelelo lwe-Thermal kunye neVibration
Ukuguquguquka kobushushu kubangela ukwanda kwe-thermal kunye nokunciphisa. Ukuba indlu ye-fan kunye ne-rotor ayilwanga kunye nemvume eyaneleyo kunye nembuyekezo ye-thermal, oku kunokukhokelela ekuxubeni, ukungcangcazela, kunye nokungaphumeleli kokuthwala. Ukwenziwa ngokuchanekileyo kunye nokulinganisa okuguquguqukayo kubalulekile ukuqinisekisa ukusebenza kakuhle phantsi komthwalo we-thermal.
