Top gas pressure recovery turbine tsamba
Chithunzi cha TRT BLAD
Sing'anga yamagetsi ya TRT turbine generator unit ndi blast ng'anjo mpweya.Tsamba la turbine ndilo gawo lalikulu la rotor system.Zida za blade ndi 2Cr13 ndipo zimayenera kulandira chithandizo chamankhwala.Tsambali ligawidwa m'magawo awiri (mwachitsanzo, magawo awiri a masamba osuntha ndi magawo awiri a masamba osunthika), pomwe 26 ndi gawo loyamba la masamba osasunthika ndipo 30 ndi gawo lachiwiri la masamba osasunthika;Pali 27 siteji yoyamba yosuntha masamba ndi 27 siteji yachiwiri yosuntha masamba.Liwiro logwira ntchito la rotor ndi 3000 rpm (liwiro loyamba lovuta kwambiri limapangidwa ngati 1800 rpm; liwiro lachiwiri lofunikira limapangidwa ngati 6400 rpm).
Ngakhale ambiri a fumbi ng'anjo akhoza kuchotsedwa pambuyo dedusting, akadali ena kuchuluka kwa ng'anjo fumbi, nthunzi madzi ndi zosiyanasiyana asidi mpweya kwaiye chifukwa chonyansa kuphulika ng'anjo zopangira, monga H2S, HCL, CO2, etc. gawo la gasi.Chifukwa cha kukula kwa unit, kutentha kumachepetsedwa pang'onopang'ono, ndipo mpweya wa acidic umasungunuka mu condensate, zomwe zimapangitsa kuti madzi a acidic amamatire pamtunda wa masamba, zipolopolo, zowonongeka ndi zigawo zina kwa nthawi yaitali.Kuphatikiza apo, ayoni a klorini mu mpweya wotentha kwambiri amamasulidwa, zomwe zimapangitsa kuti masambawo aziwonongeka kwambiri;Pa nthawi yomweyi, chifukwa cha liwiro lalikulu
Pansi pa nthawi yayitali yogwira ntchito ndi fumbi la ng'anjo yophulika, tinthu tating'onoting'ono timapitiriza kupanga kukangana kodula ndi kugwedezeka kwachindunji pa tsamba lomwe lawonongeka ndipo alibe mphamvu, zomwe zimapangitsa kuti tsambalo liwonongeke kwambiri.Tsambalo likawonongeka, kukhudzidwa kwachindunji pagawo kumakhala kosavuta komanso kugwedezeka kwakukulu.
Monga tsamba si mkulu m'malo mtengo, komanso amatenga mbali yofunika kwambiri pa ntchito otetezeka ndi mosalekeza kupanga unit, ogwira ntchito yofunika kwambiri kwa izo ndi utenga njira lolingana kukonza ndi kuteteza izo, monga laser cladding kukonza, odana ndi dzimbiri ❖ kuyanika kukonza ndi chitetezo, zitsulo ufa kupopera mbewu mankhwalawa chisanadze chitetezo, etc., amene ali ndi zotsatira zina.
