DT raupapa desulphurization papu
Tirohanga Whakaputa:
Ko nga waahanga e aukati ana i te papu e mau ana i te hangarau whaihanga rerenga whakamua hei whakapumau i te hoahoa papu pono me te tino pai o te whakahaere.
Ko nga mea whakarewa me nga taonga rapa i hangaia mo nga papu FGD kua whakamatauhia e te mahi ka taea e raatau te mahi papu roa. Na roto i te whakatikatika i nga waahanga e mau ana ki te huri i te tuunga impeller i roto i te ruma papu i nga wa katoa ka taea te whakatutuki i te mahi tino pai o te papu. Ko te papu e tohuhia ana e te hanganga patoto-muri he maamaa me te matatau.
He ngawari ki te tiaki me te whakatika, me te wetewete i nga paipa wai uru me te putanga. Ko te hiri miihini kua oti te whakamahi mo te tukanga desulphurization ka whakamahia, ka pono ana mahi
Āhuatanga Matua:
a) Ko nga waahanga maku e tango i te tātaritanga whaihanga rerenga whakamua i roto i te mahinga hoahoa hei whakapumau i te mahi pono, te pai o nga papu. Ka taea e te kaihoko te hanga i te papu kia rere tonu i roto i te ahua mahi pai ma te whakatika i nga waahanga kawe i roto i te impeller papu kia pai ki te waahi o te kohao o te papu.
b) Kua hangaia nga papu me te punaha hanganga o muri-huihui. E whakaatuhia ana e te hanganga ngawari me te ngawari ki te whakatika me te kore e wetewete i te paipa uru me te putanga o te papu. Ko te kawe mutunga ka tango i nga peera roera tapere kua kawemai me te pito taraiwa e rua nga peera roera porotakaro me te whakahinuhinu hinu angiangi. Ka taea e ia te whakatairanga i nga tohu ?? tikanga mahi ki te whakaroa i te ora o te mahi o te kawe.
c) Hangaia te hiri miihini kia rite ki te ahuatanga o te hanganga o te papu desulphurization, te ahuatanga slurry me te ahuatanga o te tono. He hiri miihini kariri. He pai te mahi, te roa o te ratonga.
d) Ko nga taputapu FGD (Flue Gas Desulfurization) o te papu he mea hanga mai i te momo hou o te rauemi Cr30 duplex kowiri tira ma te rino i hangaia e to taatau kamupene ake. Ko nga mea hou he nui te mahi atete ki te waikura me te mau. Ko te papu, te uhi papu me nga pereti splice he waahanga pehanga, he mea hanga mai i te rino whakarewa. Ko te impeller me te uhi momi he mea hanga ki te Cr30 rua-waahanga rino ma kowiri. Ko nga mea o te riipene pereti uhi, riipene anga pereti, me te raina o muri he rapa maori me te mahi abrasion pai o te taiao, he maamaa te taumaha, he iti te utu.
Mahinga Matua:
Kei te nuinga tono te reira i roto i te tipu mana mo te absorption pourewa tohanga papu ki te tuku ha'iriiri slurry.Power tipu, tipu maitai mo te hau rewharewha desulphurization.
