Izingozi Nokubusa Kwe-Dioxin

1.Umthombo we-dioxin

Ama-Dioxin yigama elijwayelekile lekilasi lezinhlanganisela ezinephunga elimnandi le-polynuclear, elifushanisiwe njenge-PCDD/Fs. Ikakhulukazi ihlanganisa i-dioxin ye-polychlorinated dibenzo-p-dioxins (pCDDs), i-diobenzofuran ye-polychlorinated (PCDFs), njll. Umthombo kanye nendlela yokwakheka kwe-dioxin iyinkimbinkimbi futhi ikhiqizwa ngokuyinhloko ngokushisa okuqhubekayo kukadoti oxubile. Lapho amapulasitiki, amaphepha, izinkuni nezinye izinto zishiswa, zizoqhekeka futhi zifake i-oxidize ngaphansi kwezimo zokushisa eziphakeme, ngaleyo ndlela zikhiqize ama-dioxin. Izici ezinomthelela zihlanganisa ukwakheka kwemfucuza, ukujikeleza komoya, izinga lokushisa elivuthayo, njll. Ucwaningo lubonisa ukuthi izinga lokushisa elilungile lokukhiqiza i-dioxin liyi-500-800 ° C, elikhiqizwa ngenxa yokuvutha okungaphelele kwemfucumfucu. Ngaphezu kwalokho, ngaphansi kwezimo zokushisa eziphansi, ngaphansi kwe-catalysis yezinsimbi eziguqukayo, izandulela ze-dioxin kanye nezinto ezincane ze-molecule zingahlanganiswa ngokusebenzisa i-catalysis yamabomu enezinga lokushisa eliphansi. Kodwa-ke, ngaphansi kwezimo ezanele ze-oxygen, izinga lokushisa elivuthayo elifinyelela ku-800-1100 ° C lingagwema ngokuphumelelayo ukwakheka kwe-dioxin.

2.Izingozi ze-dioxin

Njengomkhiqizo wokushiswa, ama-dioxin akhathaza kakhulu ngenxa yobuthi bawo, ukuphikelela kanye nokuqoqwa kwemvelo. Ama-Dioxins athinta ukulawulwa kwama-hormone omuntu kanye nezici zenkundla yomsindo, anomdlavuza kakhulu, futhi alimaze amasosha omzimba. Ubuthi bayo bulingana ne-potassium cyanide izikhathi ezingu-1 000 kanye ne-arsenic izikhathi ezingu-900. Ifakwe ohlwini njenge-carcinogen yomuntu yezinga lokuqala kanye neqoqo lokuqala lezinto ezingcolisayo ezilawulwayo ngaphansi kweNgqungquthela yaseStockholm Yokungcolisa Okuqhubekayo Kwezinto Eziphilayo.

3.Izinyathelo zokunciphisa i-dioxin ku-Gasification Incinerator System

Ukukhishwa kwegesi eliwuketshezi loHlelo Lokuqhumisa Igesi oluthuthukiswe yi-HYHH kuthobelana nezindinganiso zango-2010-75-EU kanye ne-GB18485 yaseChina. Inani elilinganisiwe elilinganisiwe lingu-≤0.1ng TEQ/m³, okunciphisa ukungcola kwesibili phakathi nenqubo yokushiswa kwemfucuza. I-Gasification Incinerator isebenzisa inqubo yokushiswa kwe-gasification + ukuze kuqinisekiswe ukuthi izinga lokushisa elivuthayo esithandweni lingaphezu kuka-850-1100 ° C futhi isikhathi sokuhlala kwegesi eliwuketshezi ngu-≥ imizuzwana emi-2, kunciphisa ukukhiqizwa kwe-dioxin emthonjeni. Isigaba segesi ye-flue ephezulu yokushisa sisebenzisa umbhoshongo wokucisha ukuze unciphise ngokushesha izinga lokushisa le-flue gas libe ngaphansi kuka-200°C ukugwema ukukhiqizwa kwesibili kwama-dioxin emazingeni okushisa aphansi. Ekugcineni, amazinga okukhishwa kwama-dioxin azofinyelelwa.
