Hei wāhanga matua o ngā pūnaha purenga hau paru hou,ngā pūwero FGD silicon carbideHe mahi nui tā tēnei i roto i ngā mara ahumahi pēnei i te mana wera me te mahi whakarewa. Kua angitu te whakaoti a tēnei pūwero uku silicon carbide i te arai hangarau o ngā pūwero whakarewa tuku iho i raro i ngā āhuatanga waikura kaha me te kakahu teitei mā te hoahoa hanganga auaha me ngā putanga rauemi hou, e whakapai ake ana i te pai o te tango whanariki.
1, Ko ngā āhuatanga rauemi te pūtake mō te mahi
Te pakeketanga o te Mohsngā uku karāhe siliconKa eke ki te 9.2, ko te tuarua anake ki te taimana, ā, ko tōna pakari pakaru e toru ngā wā i te kaha o ngā uku alumina. Nā tēnei hanganga tioata honohono ka tino pai te ātete ki te pakū o te rauemi, ā, i raro i te pānga o te paru tere-teitei kei roto ngā tioata gypsum (tere rere tae atu ki te 12m/s), ko te tere kakahu o te mata he 1/20 noa iho i te tere kakahu o ngā pūwero whakarewa. I roto i te taiao tauutuutu waikawa-pūtake me te uara pH o te 4-10, ko te tere ātete waikura o te silicon carbide he iti iho i te 0.01mm/tau, he pai ake i te 0.5mm/tau o te maitai kore waikura 316L.
He tata te tauwehenga whānui wera o te rauemi (4.0 × 10⁻⁶/℃) ki tērā o te maitai, ā, ka taea tonu te pupuri i te pumau hanganga i raro i te rerekētanga pāmahana o te 150℃. Ko ngā uku silicon carbide i hangaia mā te tukanga sintering tauhohenga he nui ake i te 98% te mātotoru, ā, he iti iho i te 0.5% te porosity, e ārai ana i te kino hanganga i puta mai i te urunga o te reo.
2, Tikanga atomization tino tika me te mana whakahaere mara rere
Tepūwero porowhita silicon carbideKa tino whakanuia te tere hurihuri o te paru, ā, mā te whakatuwheratanga tika, ka pakaru te paru kōhatu ki ngā pata iti, ōrite hoki. He tino nui te tere taupoki o te papa rehu kōhao i hangaia e tēnei hanganga, ā, ka roa ake te wā noho o ngā pata i roto i te pourewa ki te 2-3 hēkona, 40% teitei ake i tērā o ngā pūwero tuku iho.
3, Te whakataurite pūnaha me te arotau hangarau
I roto i tētahi pourewa rehu noa,ngā pūwero FGD silicon carbideKa whakamahia ngā mea kua whakaritea kia rite ki te papa tīhi, me te tawhiti o te 1.2-1.5 ngā wā o te whānui o te kōne rehu, ka hanga he 3-5 paparanga o te whakakikorua. Mā tēnei whakaritenga ka neke ake te kapi whakawhiti-wāhanga o te pourewa whakakorenga whanariki i te 200%, ka whakarite kia rawaka te whakapā i waenga i te hau paru me te paru. Mā te tere rere o te pourewa kau he 3-5 m/s, ka whakahaeretia te ngaronga pēhanga o te pūnaha i roto i te awhe o te 800-1200 Pa.
E whakaatu ana ngā raraunga whakahaere kei te pumau tonu te whai huatanga o te pūnaha FGD e whakamahi ana i ngā pūwero silicon carbide i runga i te 97.5%, ā, kua heke te nui o te makuku o ngā hua taha gypsum ki raro iho i te 10%. Kua whakaroahia te huringa tiaki taputapu mai i te 3 marama mō ngā pūwero whakarewa ki te 3 tau, ā, kua heke te utu mō te whakakapinga o ngā wāhanga e manawapa ana mā te 70%.
Ko te tono o tēneiPūwero FGDHe tohu tēnei i te peke mai i ngā taputapu tiaki taiao whānui ki ngā taputapu tiaki taiao tino tika. I te pakari o te hangarau uku tā 3D, tera pea ka tutuki te hoahoa arotautanga o te hanganga awa rere i te heke mai, ka taea ai te whakapai ake i te whai huatanga o te atomization mā te 15-20% me te whakatairanga i te hangarau tukunga tino iti ki te tomo ki tētahi wāhanga hou o te whanaketanga.
