ʻenehana hoʻoheheʻe Catalytic

1 Kūlana ʻenehana

ʻO ka hoʻomohala waiwai a me ka pilikanaka a me ka noi no ka ʻenehana e hana i ka ʻenehana catalytic, ʻoi aku ka ʻenehana catalytic combustion, e lilo i mea pono ʻenehana ʻenehana ponoʻī, a me ka hoʻomaikaʻi ʻana i ka nohona o nā kānaka a me ka ulu ʻana o ka noi, e hoʻomau ka ʻoihana catalytic e komo i nā tausani o hale, i loko o ke ola o kanaka. Ua hoʻomaka ke aʻo ʻana i ka hoʻopau ʻana i ka catalytic mai ka loaʻa ʻana o ka hopena catalytic o ka platinum ma ka puhi ʻana i ka methane. He kuleana koʻikoʻi ka hoʻopau ʻana i ka catalytic i ka hoʻomaikaʻi ʻana i ke kaʻina hana, hoʻemi i ka wela o ka hopena, hoʻoikaika i ka hoʻopau piha ʻana, a ke kāohi nei i ka hoʻokumu ʻana o nā mea ʻawaʻawa a me nā mea ʻino, a ua hoʻohana nui ʻia i nā ʻano he nui o ka hana ʻoihana a me ke ola o kēlā me kēia lā.

2.ʻO ke kumu a me nā pōmaikaʻi o ka hoʻopau catalytic

Catalytic combustion mea he typical gas-solid phase catalytic reaction, hoemi ia i ka ikehu hoala o ka hopena me ke kokua ana o ka catalyst, no laila, he flameless combustion ma ka haʻahaʻa ignition wela o 200 ~ 300 ℃. ʻO ka oxidation o ka mea ola ma luna o ka ʻili o ka catalyst paʻa, ʻoiai e hana ana i CO2 a me H2O, a me ka hoʻokuʻu ʻana i ka wela nui, no ka haʻahaʻa haʻahaʻa haʻahaʻa. No laila, ʻaʻole nui ka N2 i ka lewa e hana i ka NOx wela kiʻekiʻe. Eia kekahi, ma muli o ke koho koho ʻana o ka catalyst, hiki ke kaupalena i ke kaʻina oxidation o nā pūhui i loaʻa naikokene (RNH) i loko o ka wahie, no laila ka hapa nui o lākou e hana i ka molecular nitrogen (N2).

Ke hoʻohālikelike ʻia me ka puhi ahi maʻamau, ʻoi aku ka maikaʻi o ka puhi ʻana i ka catalytic:

(1) He haʻahaʻa ka mahana wela, haʻahaʻa ka hoʻohana ʻana i ka ikehu, maʻalahi ka paʻa ʻana o ka puhi ʻana, a hiki ke hoʻopau ʻia ka hopena oxidation me ka ʻole o ka hoʻoili wela o waho ma hope o ka mahana wela.

(2) ʻO ka hoʻomaʻemaʻe hoʻomaʻemaʻe kiʻekiʻe, ka pae haʻahaʻa haʻahaʻa o nā mea haumia (e like me NOx a me nā huahana hoʻopau ʻole, etc.).

(3) Nui ka nui o ka oxygen, ka leo haʻahaʻa, ʻaʻohe pollution lua, hoʻopau haʻahaʻa, nā kumukūʻai haʻahaʻa, a me ka hoʻokele hana maʻalahi.

3 Hoʻohana ʻenehana

ʻO ke kaʻina hana o ka petrochemical, ka pena, ka electroplating, ka paʻi ʻana, ka uhi ʻana, ka hana ʻana o nā kaila a me nā ʻoihana ʻē aʻe e pili ana i ka hoʻohana ʻana a me ka hoʻokuʻu ʻana i nā mea hoʻohuihui organik. ʻO ka mea maʻamau ka mea hoʻopuʻupuʻu ʻino, ʻo ia nā pūhui hydrocarbon, oxygen-containing organic compounds, chlorine, sulfur, phosphorus and halogen organic compounds. Inā hoʻokuʻu pololei ʻia kēia mau mea hoʻohuihui kūlohelohe i ka lewa me ka ʻole o ka mālama ʻana, e hoʻopōʻino ʻia lākou. ʻO nā ʻano hana hoʻomaʻemaʻe kinoea kūlohelohe kuʻuna (e like me adsorption, condensation, combustion pololei, a me nā mea ʻē aʻe) he mau hemahema, e like me ka maʻalahi o ka hoʻohaumia lua. I mea e lanakila ai i nā hemahema o nā ʻano hana hoʻomaʻemaʻe kinoea kūlohelohe, hoʻohana ʻia ke ʻano catalytic combustion e hoʻomaʻemaʻe i ke kinoea ʻōpala organik.

Catalytic combustion method is a practical and simple organic waste gas purification technology, the technology is the deep oxidation of organic molecules on the surface of the catalyst into harmless carbon dioxide and water method, also known as catalytic complete oxidation or catalytic deep oxidation method. mea e pili ana i ka catalytic combustion 'enehana no ka 'oihana benzene 'ōpala kinoea, e hoʻohana i ka haʻahaʻa-kumuai ole-makamae metala catalyst, ka mea i basically haku o CuO, MnO2, Cu-manganese spinel, ZrO2, CeO2, zirconium a me cerium paʻa solution, ka mea. hiki ke hoemi loa i ka wela o ka hopena o ka catalytic combustion, hoʻomaikaʻi i ka hana catalytic, a hoʻolōʻihi i ke ola o ka catalyst. ʻO ka mea i hana ʻia e pili ana i ka catalytic combustion catalyst, ʻo ia ka catalytic combustion catalyst no ka hoʻomaʻemaʻe ʻana i ke kinoea ʻōpala, ʻO ka ʻili o ka honeycomb ceramic skeleton, kahi uhi ma luna o ia mea a me kahi mea hana metala hanohano. kūʻē. Hoʻouka ʻia nā mea hana o nā metala makamae e ke ʻano impregnation, a ʻoi aku ka kiʻekiʻe o ka hoʻohana pono ʻana.
