Iingozi kunye noLawulo lweDioxin

1.Umthombo we dioxin

IiDioxins ligama eliqhelekileyo leklasi yeekhompawundi ezinevumba elimnandi zepolynuclear, ezifinyeziweyo njengePCDD/Fs. Ikakhulu ibandakanya i-dioxins ye-polychlorinated dibenzo-p-dioxins (i-pCDDs), i-dibenzofurans ye-polychlorinated (i-PCDFs), njl njl. Umthombo kunye nendlela yokwenza i-dioxin inzima kwaye iveliswa ngokuyinhloko ngokutshiswa okuqhubekayo kwenkunkuma exutywe. Xa iiplastiki, iphepha, iinkuni kunye nezinye izinto zitshiswa, ziya kuqhekeka kwaye zifake i-oxidize phantsi kweemeko eziphezulu zokushisa, ngaloo ndlela zivelise i-dioxins. Izinto ezichaphazelayo ziquka ukubunjwa kwenkunkuma, ukujikeleza komoya, ukushisa okutshisayo, njl. Ukongeza, phantsi kweemeko zobushushu obuphantsi, phantsi kwe-catalysis yesinyithi senguqu, i-dioxin precursors kunye nezinto ezincinci ze-molecule zinokudityaniswa nge-catalysis ephantsi yobushushu obuphantsi. Nangona kunjalo, phantsi kweemeko ezaneleyo ze-oksijeni, ukushisa okutshisayo ukufikelela kwi-800-1100 ° C kunokuphepha ngokufanelekileyo ukubunjwa kwe-dioxin.

2.Iingozi ze-dioxin

Njengemveliso yokutshisa, ii-dioxins zixhalabisa kakhulu ngenxa yetyhefu, ukuzingisa kunye ne-bioaccumulation. IiDioxins zichaphazela ukulawulwa kweehomoni zabantu kunye nezinto ezivakalayo zentsimi, ziyingozi kakhulu, kwaye zonakalise amajoni omzimba. Ubutyhefu bayo bulingana ne-1,000 ye-potassium cyanide kunye ne-900 ye-arsenic. Idweliswe njengenqanaba lokuqala le-carcinogen yomntu kunye nenye yebhetshi yokuqala yezinto ezingcolisayo ezilawulwayo phantsi kweNgqungquthela yaseStockholm kwi-Persistent Organic Pollutants.

3.Amanyathelo okunciphisa idioxin kwiGasification Incinerator System

Ukukhutshwa kwegesi ye-flue ye-Gasification Incinerator System eyenziwe yi-HYHH ihambelana ne-2010-75-EU kunye nemigangatho ye-GB18485 yaseChina. Ixabiso lomndilili olinganisiweyo ngu ≤0.1ng TEQ/m³, okunciphisa ungcoliseko lwesibini ngexesha lenkqubo yokutshiswa kwenkunkuma. I-Gasification Incinerator ithatha i-gasification + inkqubo yokutshisa ukuze kuqinisekiswe ukuba ukushisa okuvuthayo kwisithando somlilo kungaphezulu kwe-850-1100 ° C kunye nexesha lokuhlala kwegesi ye-flue ≥ imizuzwana ye-2, ukunciphisa ukuveliswa kwe-dioxin ukusuka kumthombo. I-high-temperature flue gas section isebenzisa inqaba yokucima ngokukhawuleza ukunciphisa ukushisa kwegesi ye-flue ukuya ngaphantsi kwe-200 ° C ukuphepha ukuveliswa kwesibini kweedioxin kumaqondo aphantsi. Ekugqibeleni, imigangatho yokukhutshwa kwee-dioxins iya kufezekiswa.
