Ekifo kyapolyacrylamide ((PAM) mu nkola y'okwokya ebisaasaanyizo esinga okussa essira ku nkola y'okulongoosa omukka oguyitibwa flue gas, naddala mu nkola y'okulongoosa omukka oguyitibwa flue gas oguyitibwa semidry. Omulimu gwayo omukulu kwe kukola nga flocculant okulongoosa obulungi bw'okuggya enfuufu. Tekikozesebwa butereevu mu nkola y'okukyusa era tekikozesebwa mu kukoma enkuba (kye kifo kya simenti oba ebikozesebwa mu kutwala).

Bino bye bikolwa eby'enjawulo, ebikolwa n'emitendera gy'okukozesaPAMmu kifo ekikozesebwa mu kuzisa ebirime:

Ekitundu ky'okukozesa: Nga tonnakuŋŋaanya enfuufu oluvannyuma lw'enteekateeka y'okusaasaanya sulfur ya spray drying reactor (SDA) oba enteekateeka y'okusaasaanya sulfur ya circulating fluidized bed (CFB)

Mu nkola ya desulfurization ey'ekitundu ekikalu (eno y'emu ku nkola za desulfurization ezisinga okukozesebwa mu kuzika ebisaasaanyizo), omusaayi gw'omusaayi gw'omusaayi gw'omusaayi gw'omusaayi gw'omusaayi gw'omusaayi gw'omusaayi gw'omusaayi gw'omusaayi gw'omusaayi gw' ₂, HCl, HF, n'ebirala) mu gaasi ey'omukka ey'ebbugumu erya waggulu okukola ebitundu by'omunnyo ogunywevu (gamba nga CaCl ₂, CaSO₃, CaSO₄) ne lime etakolebwa.

Mu kiseera kye kimu, omukka gw'omukka gulimu n'omuwendo omunene ogw'enkuba ez'omu kiseera ekisooka, ebitundu bya carbon ebitafuuka, ebitundu by'ebyuma ebinene, n'ebitundu ebitonotono ebiva mu nkola eno.

Ebintu bino (naddala ebitundu ebipya ebiva mu kukozesa n'obufuvu bw'omukka obutonotono obutafaanaganyizibwa) bitera okuba ebirungi nnyo era bikizibu okukwatibwa obulungi n'ebyuma ebiddako eby'okuggyawo enfuufu (gamba ng'ebikozesebwa mu kukuŋŋaanya enfuufu ez'ekika ky'ensawo oba ebikozesebw

Omulimu omukulu: Okufulumya

Polyacrylamide (emirundi mingi anionic PAM) esobozesebwa era esobozesebwa mu muyaga oba mu kifo ekikozesebwa wakati w'okufuluma kw'ekizimbe ky'okukozesa n'okuyingira kw'ekikozesebwa mu kukuŋŋaanya enfuufu ku kigero ekitono ennyo (ppm level).

PAM polymer ey'ekitundu ekiwanvu. Ebibinja ebikozesebwa ku mukutu gwayo ogw'ebitundu (nga ebibinja bya amide) biyinza okunywa ebitundu bingi eby'enfuufu ebitonotono okuyita mu kukwatagana n'ebikolwa eby'okuziyiza ebitundu (okusingira ddala ebitundu ebitonotono eby'ekitundu kya anionic PAM bikolerana n'ebitundu ebiriko ebi

Ebintu ebikozesebwa mu kukyusa bino bigenda okumpi era ne bikwatagana okukola ebitundu ebinene. Enkola eno eyitibwa flocculation.

Ebintu ebikulu:

Okulongoosa nnyo obulungi mu kuggya enfuufu: Kino kye kintu ekisinga okuba eky'omugaso. Ebitundu ebinene ebikolebwa oluvannyuma lw'okufulumya PAM birina amangu ag'okweyongera okw'okusaasaanya n'obuzibu, ekifuula okuba ennyangu okuggibwawo obulungi n'ebikozesebwa mu kukuŋŋaanya enfuufu eby'ekika ky'ensawo (okuziyiza ensawo z'okuziyiza) oba ebikozesebwa mu kukuŋŋaanya enfuufu ez'amasannyala Kino kikendeeza butereevu ku bungi bw'enfuufu (ebitundu) mu gaasi y'omukka.

Okulongoosa ebikolwa by'ensawo z'ebikozesebwa mu kufulumya (ku bikolwa by'ebikozesebwa mu kufulumya ensimbi ez'ekika ky'ensawo):

Oluvannyuma lw'okukola ebitundu ebinene, ekitundu ky'enfuufu (filter cake) ekikolebwa ku nsawo y'ekitundu kino kirina obusobozi obulungi obw'okutambula empewo, ekikendeeza ku buzibu bw'okutambula.

Obusobozi bw'ebitundu ebitonotono okuyingira mu bintu ebikozesebwa mu kufulumya oba okuziyiza ebitundu ebikozesebwa mu kufulumya bukendeera, ekiyamba okwongera ku bulamu bw'ekisenge ky'ekisenge.

Ekitundu ky'enfuufu ekikolebwa kyangu okulongoosebwa, nga kino kyongera okulongoosa obulungi.

Okwongera ku bukolero bw'okuggyawo acid (mu butereevu): Ebintu eby'omukka ebitalina kuddamu ebikwatibwa okuyita mu flocculation bikendeeza ku bungi bwabyo ebiva mu gaasi y'omukka. Ekitundu ekikwatibwa mu kisenge ky'enfuufu ku nsawo y'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky'ekisaawe ky

Okukendeeza ku kukozesebwa kw'ebikozesebwa: Okukendeeza ku kukozesebwa kw'ebikozesebwa ebiddako gamba nga fan eya draft eyakolebwa ebitundu ebitonotono.

Okwongera ku bintu eby'omufuba oguvuga (obusobozi): Ebintu ebinene ebikolebwa okuva mu kufulumya biyinza okuleetawo enkyukakyuka ezimu mu bintu eby'omubiri eby'omufuba oguvuga (gamba ng'okusaasaanya obunene bw'ebitundu n'okusaasaanya), naye kino si kye kigendere

Ebintu by'okukozesa:

Okulonda ekika: Anionic polyacrylamide ekozesebwa nnyo mu kunyonja omukka oguyitibwa fume gas. Kino kivudde ku kuba ebitundu by'enfuufu (ebifuba ebivuga, ebikozesebwa mu kukozesa) mu gaasi y'omukka kitera okuba n'ebikozesebwa ebikalu mu mbeera ezimu (naddala mu nkola ez'ekitundu ekikalu), era PAM eya anionic etuuka ku kufulumya okw'omugaso okuyita mu kufulumya ebikozesebwa n'oku Cationic PAM ekozesebwa nnyo mu kuyonja amazzi, naye tekikozesebwa nnyo mu kufulumya gaasi y'omukka. Ekika kya nonionic oluusi kikozesebwa mu mbeera ez'enjawulo.

Ekifo eky'okuteekawo: Kilina okuba oluvannyuma lw'ekizimbe ky'okukozesa n'oluvannyuma lw'ekizimbe ekikuŋŋaanya enfuufu. Kitera okuteekebwa mu kifo ekiriko omukka oguyitibwa flue gas mu kizimbe ky'okukyusa oba mu kisenge eky'okukyusa eky'okukyusa eky'okukyusa eky'okukyusa eky'okukyusa eky'okukyusa eky'okukyusa. Ekifo ky'okusaasaanya kyetaaga obuzibu obumala okukakasa nti ekirungo kya PAM n'omukka gw'omukka bikwatagana bulungi.

Enkola y'okusiiga: Enkola y'okusiiga entono nnyo, emirundi mingi ku mutindo gwa ppm. Enkola z'okupimira n'okugaziya ez'obulungi zeetaagisa. Okukozesebwa okw'amaanyi kiyinza okuviirako ebisenge okuziyitibwa, okuziyitibwa, oba okukendeeza ku nkola.

Okufulumya n'Okukula: PAM yeetaaga ekikozesebwa eky'enjawulo eky'okufuulumya (nga tanki y'okufuulumya) okufuulumya n'okufuulumya (ekikkiriza obubonero bwa molekyuli okugaziya mu bujjuvu), okusobola okutuuka ku nkola esinga obulungi ey'okufuulumya. Okunyumirwa obubi kujja kuleetawo ebitundu bya gel ebifaanana n'amaaso g'ebyennyanja, ebikola obubi era nga bisobola okuziyiza ebitundu by'emipiira.

Okukolerana n'Abakozesa Abalala: Okufulumya kwa PAM kitera okukozesebwa awamu n'ekirungo ky'omukka (deacidifier), carbon ekikozesebwa (adsorbing dioxins/ 重金属)， n'ebirala, okutuukiriza awamu ekigendererwa eky'okulongoosa omukka gw'omukka. Ekiwandiiko:

Mu nkola y'okwokya ebisenge, polyacrylamide (PAM) ekozesebwa okusingira ddala mu kitundu eky'okusembayo eky'enteekateeka y'okulongoosa omukka oguyitibwa flue (oluvannyuma lw'okusaanyizibwa n'okutannaba kufulumya enfuufu), ng'ekikozesebwa ng'ekikozesebwa mu kufulu Kino kituukiriza nga kigatta ebitundu by'enfuufu ebitonotono (nga mw'otwalidde n'enkuba ey'okuvuga, ebitundu ebikozesebwa mu kuddamu okukozesa ensulfurization, ekikalu ekitaakolebwawo, n'ebirala) mu bitundu ebinene, nga kino kyongera nnyo ku busobozi bw'okukwata ebitundu ebikozesebwa mu kuddamu okukozesa ensulfurization (naddala ebitundu ebikozesebwa mu kuddamu okukozesa ensulfurization), n Okukozesebwa kwayo kutono naye ebikolwa byayo bikulu nnyo. Kimu ku nkola enkulu ez'okuyamba okukakasa nti omukka oguva mu bifo ebikozesebwa mu kuzisa ebirime gutuukiriza emitindo (naddala okufuga omuwendo gw'ebitundu). Tekyenyigira mu nkola y'okukyuka era tekikozesebwa mu kulongoosa okw'enkomerero okw'okunywera kw'enkuba ez'omukka.
