kiʻi 1Halekiai Desulfurization

ʻO ka ʻōnaehana hoʻoheheʻe kinoea hoʻopau he mea hana ko'iko'i i ho'ohana 'ia no ka ho'emi 'ana i ka sulfur dioxide (SO2) ma loko o ke kinoea. He ākea kona kumu hana a me ka hoʻohana ʻana.

ʻO kēia ka ʻōlelo kikoʻī e pili ana i ka exhaust ʻO ke kinoea Desulfurization ʻōnaehana:

1.Ke kumu hana

Hoʻokaʻawale ʻia ke kumu hana o ka ʻōnaehana desulfurization hoʻopau i ka desulfurization pulu a me ka desulfurization maloʻo:

kiʻi 2 Ka papa kuhikuhi o ka ʻōnaehana desulfurization kinoea

Wet desulfurization:ʻO Wet Desulfurization kekahi o nā ʻenehana desulfurization i hoʻohana nui ʻia. Ma ke kaʻina hana desulfurization pulu, hoʻohana mau ʻia nā hopena alkaline e like me ka limestone slurry a i ʻole ka sodium hydroxide e like me ka absorbents. Ke hele ka ʻeaea i loko o ka hale kiaʻi desulfurization, hoʻopili piha ʻia me ka noe wai a i ʻole ka hopena alkaline i hoʻoheheʻe ʻia mai ka papa hoʻoheheʻe. Hoʻopili ʻia ka sulfur dioxide i loko o ke kinoea puhi e ka mea hoʻoheheʻe a hana kemika e hana i nā sulfate (e like me ka calcium sulfite a i ʻole calcium sulfate). A laila, hiki ke hana hou ʻia kēia mau sulfates, e like me ka oxidation, crystallization, etc., e hana i nā huahana e like me ka gypsum.

kiʻi 8 Desulfurization hale kiaʻi haku haku mele

Desulfurization maloʻo:ʻAʻole hoʻohana ka desulfurization maloʻo i ka wai a i ʻole ka hopena, akā hoʻohana i nā mea hoʻoheheʻe maloʻo (e like me ke kalapona i hoʻāla ʻia, calcium oxide, a me nā mea ʻē aʻe) e hoʻopili i ka sulfur dioxide i loko o ke kinoea. He mea maʻamau kēia ʻano no nā manawa i haʻahaʻa ka ʻike o ka wai i loko o ke kinoea puhi a pono e pale ʻia ka wai ʻino.

2.System haku mele

Hoʻokomo pinepine ʻia ka ʻōnaehana desulfurization ʻōpala i nā ʻāpana nui:

Pūnaehana kinoea puhi: Hoʻokumu ʻia ia me ka puka inlet flue gas damper, bypass flue gas damper door, steel flue, etc., nona ke kuleana no ka hoʻokomo ʻana i ke kinoea i loko o ka sulfur dioxide i loko o ka ʻōnaehana desulfurization.

Pūnaehana hoʻomākaukau absorbent (ʻano pulu): E like me ka limestone slurry hoʻomākaukau ʻōnaehana, me ka limestone pauda silo, vibrating hopper, ke kaupaona ʻana i nā mea hana, ka meaʻai slurry, ka mīkini hoʻomākaukau slurry, a me nā mea ʻē aʻe, i hoʻohana ʻia e hoʻomākaukau i ka absorbent e pono ai no ka desulfurization.

hale kiaʻi desulfurization: ʻO ka hale kiaʻi desulfurization ka mea nui o ka ʻōnaehana desulfurization. Hoʻopili ke kinoea i ke kino me ka absorbent i loko o ka hale kiaʻi e hoʻokō i ka hopena desulfurization. Hoʻolako pinepine ʻia ka hale kiaʻi desulfurization pulu me kahi papa hoʻoheheʻe a me kahi papa packing e hoʻomaikaʻi i ka pono desulfurization.

kiʻi 9 Hale kiaʻi desulfurization

Pūnaehana dehydration gypsum (ʻano pulu):No nā huahana like ʻole e like me ka gypsum i hana ʻia e ka desulfurization pulu, koi ʻia ka mālama dehydration no ka hoʻohana ʻana a i ʻole ka hoʻokuʻu ʻana.

Pūnaehana ʻenekinia lehulehu: E komo pū me ka ʻōnaehana wai kaʻina, ʻōnaehana hāʻawi mana haʻahaʻa haʻahaʻa a me ka ʻōnaehana ea paʻa, a me nā mea ʻē aʻe, e hāʻawi i nā kūlana hana pono no ka ʻōnaehana desulfurization.

Pūnaehana kiaʻi ʻana i ke kinoea hoʻomau (CEMS):hoʻohana ʻia no ke ana ʻana i nā ʻāpana kinoea flue o ka mea desulfurization i ka manawa maoli, hāʻawi i ka ʻikepili no ka hoʻoponopono ʻana i nā ʻāpana hana o ka mea desulfurization, e hōʻoia i ka hana maʻamau o ka hāmeʻa, a hāʻawi i ka ʻikepili no ka loiloi hana o ka mea desulfurization.

3.Application Scope

ʻO ka ʻōnaehana hoʻoheheʻe kinoea hoʻopau hoʻohana nui ʻia i nā ʻano ʻoihana like ʻole, ʻoi aku ka nui o nā ʻoihana e koi ana i ka nui o nā hopena kemika a hana i ke kinoea flue i loaʻa i ka sulfur dioxide, e like me ka petrochemical, ka hoʻomaʻemaʻe aila, metallurgy, fertilizers kemika, ke kila, ka uila, a me nā mea ʻē aʻe. kaiapuni.

4. Nā Pono Hana

ʻO ka ʻōnaehana hoʻoheheʻe kinoea hoʻopau He nui nā pono ʻenehana, e like me ke kiʻekiʻe o ka desulfurization maikaʻi, ke ʻano hana maʻalahi, ka hoʻohana ākea, a me nā huahana pili kaiapuni. Eia kekahi, me ka hoʻomau mau ʻana o ka ʻenehana, hoʻomaikaʻi mau ʻia ka ʻōnaehana desulfurization ʻōpala e hoʻomaikaʻi i ka pono desulfurization, hoʻemi i nā kumukūʻai hana a hōʻemi i ka hopena o ke kaiapuni.

5. Hōʻuluʻulu manaʻo

kiʻi 10 ʻO nā mea hana hoʻoheheʻe kinoea

I ka hōʻuluʻulu ʻana, ʻo ka ʻōnaehana desulfurization kinoea he mea koʻikoʻi ka mālama ʻana i ke kaiapuni, he mea nui ia no ka hōʻemi ʻana i ka ʻike o ka sulfur dioxide i nā hoʻokuʻu ʻoihana a me ka pale ʻana i ke kaiapuni a me ke olakino kanaka.
