Ngā pūwero rehu FGD

I te wāhi o te Pakanga Tiaki o te Rangi Kahurangi, kei reira tētahi 'rangatira matua' kāore i te tino mōhiotia e tiaki puku ana i tō tātou hauora manawa – ehara i te pourewa mimiti nui, ehara hoki i te pūnaha whakahaere matatini, engari hepūwero whakakorenga whanariki hau korere (pūwero rehu FGD)he torutoru tekau mirimita noa te whānui – ko tēnei wāhanga iti ngaro te uho o te whai huatanga o te pūnaha whakakorenga whanariki katoa.
Hei "korokoro" o te pūnaha whakakorenga whanariki, me tu te pūwero i te "whakamātautau toru" o te pāmahana teitei, te waikura kaha, me te kakahu nui. He maha ngā raruraru ka pā ki ngā rauemi whakarewa tuku iho pērā i te whānui o te pore me te korenga o te atomization i muri i ētahi marama o te horonga e ngā paru waikawa; Ahakoa he ātete ki te waikura ngā kirihou hangarau, he uaua ki te tu atu i ngā pāmahana teitei tonu. I tēnei wā, ko tētahi whakatutukitanga nui mai i te pūtaiao rauemi hou - ko ngā uku silicon carbide kua tauhohenga, kei te tuhi anō i ngā paerewa ahumahi.
Ko tēnei momo uku hou, e mōhiotia ana ko te "koura pango ahumahi," he āhuatanga whakamiharo kei te taumata moroiti: miriona ngā tioata silicon carbide e hanga ana i tētahi whatunga matotoru mā roto i ngā tukanga sintering motuhake, ka hanga he pakeke e rite ana ki te taimana. Ina horoia te paru desulfurization kei roto ngā matūriki gypsum i te pēhanga teitei me te tere, he iti ake tōna tere kakahu i tērā o te maitai noa. Ko te mea nui ake, he "mana nui" taiao tōna hei ātete i te waikura waikawa me te kawakore, ā, ka taea te pupuri i tōna tinana kore e taea te whakangaro ahakoa i raro i ngā āhuatanga o ngā huringa pH kino.

Mō te pumau, he roa te ora o tēnei rauemi. Ka whakahaeretia tonutia te koki whakakorikori o tēnei pūwero rauemi i roto i tētahi whānuitanga iti rawa i muri i ētahi tau, ā, mā tēnei kaha pupuri tika ka roa ake te huringa tiaki taputapu.
Mō ngā kiritaki e hiahia ana ki te whakamahi i ngā pūnaha whakakorenga whanariki, ko te whiriwhiri i ngā pūwero waro silicon he rite ki te hoko "inihua ora" mō ngā taputapu. Ehara i te mea ka whakaiti noa i te utu o te whakakapinga o ngā wāhanga e manawapa ana, engari he mea nui ake, ka whakarite i te pumau tonu o te whai huatanga o te whakakorenga whanariki – e pā tika ana ki ngā paerewa tiaki taiao me te whakaputa pumau o ngā umanga.
Ko ngā wāhanga o te pūwero i hangaia mā te whakamahi i te hangarau miihini tika kua patenttia, ka whakamatautauria kia tino pakari, tae atu ki te whakamātautau atomization, i mua i te wehenga atu i te wheketere kia tino hurihia ai ngā painga ā-roto o te rauemi hei painga ā-tinana mō te taiao.
I te haerenga hou e arahina ana e te whāinga "waro rua", kei te werohia e te auahatanga hangarau te ora roa ki roto i ngā taputapu tiaki taiao. Ko te whakamahinga whānui o ngā pūwero uku silicon carbide kua whakatahehia he tohu mārama ki te huringa rauemi e whakamana ana i te hanga matomato. Ina titiro ake tātou ki te rangi kikorangi mārama, ka whakaaro pea tātou ki ēnei "kaitiaki uku" kua huna i ō rātou pūkenga me te rongonui - kei te tiaki rātou i te parakore o ngā mano mita me te manawanui taumata mirimita.
