ʻO nā pōʻino a me ke aupuni o ka Dioxin

1.Ke kumu o ka dioxin

ʻO Dioxins ka inoa maʻamau no kahi papa o nā pūhui ʻala polynuclear chlorinated, i hoʻopau ʻia ʻo PCDD/Fs. Hoʻokomo nui ʻia ka polychlorinated dibenzo-p-dioxins (pCDDs), polychlorinated dibenzofurans (PCDFs), etc. He paʻakikī ke kumu a me ka hoʻokumu ʻana o ka dioxin a ua hana mua ʻia e ke puhi mau ʻana i nā ʻōpala hui ʻia. Ke puhi ʻia nā plastic, pepa, lāʻau a me nā mea ʻē aʻe, e haki a oxidize ma lalo o nā kūlana wela kiʻekiʻe, pēlā e hana ai i nā dioxins. ʻO nā mea e hoʻoulu ai e pili ana i ka hoʻohui ʻana i ka ʻōpala, ke kahe ʻana o ka ea, ka wela wela, a me nā mea ʻē aʻe. Ua hōʻike ka noiʻi ʻana ʻo ka pae wela maikaʻi loa no ka hana dioxin he 500-800°C, i hana ʻia ma muli o ka hoʻopau ʻole ʻana o ka ʻōpala. Eia kekahi, ma lalo o nā kūlana haʻahaʻa haʻahaʻa, ma lalo o ka catalysis o nā metala hoʻololi, nā dioxin precursors a me nā mea mole liʻiliʻi hiki ke synthesized ma o ka catalysis intentional haʻahaʻa. Eia naʻe, ma lalo o nā kūlana oxygen kūpono, hiki i ka mahana wela ke hiki i 800-1100 ° C ke pale pono i ka hoʻokumu ʻana o dioxin.

2.ʻO ka pōʻino o ka dioxin

Ma ke ʻano he hopena o ka puhi ʻana, hopohopo nui nā dioxins ma muli o ko lākou ʻona, hoʻomau a me ka bioaccumulation. Hoʻopilikia ʻo Dioxins i ka hoʻoponopono ʻana i nā hormones kanaka a me nā kumu kahua kani, he carcinogenic nui, a hōʻino i ka ʻōnaehana pale. Ua like kona ʻona me 1,000 mau manawa o ka potassium cyanide a me 900 mau manawa o ka arsenic. Ua helu ʻia ʻo ia ma ke ʻano he carcinogen kanaka pae mua a ʻo kekahi o ka pūʻulu mua o nā mea haumia i mālama ʻia ma lalo o ka Stockholm Convention on Persistent Organic Pollutants.

3.Nā hana e hōʻemi i ka dioxin i loko o ka Gasification Incinerator System

ʻO ka hoʻokuʻu ʻia ʻana o ke kinoea o ka Gasification Incinerator System i hoʻomohala ʻia e HYHH e hoʻokō me nā kūlana 2010-75-EU a me Kina GB18485. ʻO ka waiwai awelika i ana ʻia ʻo ≤0.1ng TEQ/m³, ka mea e hō'emi i ka pollution lua i ka wā o ke ka'ina hana 'ōpala. Hoʻohana ka Gasification Incinerator i ke kaʻina hana gasification + incineration no ka hōʻoia ʻana i ka mahana wela o ka umu ma luna o 850-1100 ° C a ʻo ka manawa noho o ka flue gas he ≥ 2 kekona, e hōʻemi ana i ka hana ʻana o ka dioxin mai ke kumu. Hoʻohana ka ʻāpana ʻeaea wela kiʻekiʻe i ka hale kiaʻi hoʻopau e hoʻemi koke i ka mahana o ke kinoea ma lalo o 200°C e pale aku i ka hana lua o nā dioxins ma nā haʻahaʻa haʻahaʻa. ʻO ka hope, e hoʻokō ʻia nā kūlana hoʻokuʻu o nā dioxins.
