Ihe egwu na ọchịchị nke Dioxin

1.Isi mmalite nke dioxin

Dioxins bụ aha izugbe maka klaasị nke ogige aromatic polynuclear chlorinated, nke akpọrọ PCDD/Fs. Nke kachasị na-agụnye polychlorinated dibenzo-p-dioxins (pCDDs), polychlorinated dibenzofurans (PCDFs), wdg. Isi mmalite na usoro nhazi nke dioxin dị mgbagwoju anya ma na-emepụta bụ isi site na ọkụ na-aga n'ihu nke ihe mkpofu agwakọta. Mgbe a na-ere plastik, akwụkwọ, osisi na ihe ndị ọzọ ọkụ, ha ga-agbawa na oxidize n'okpuru ọnọdụ okpomọkụ dị elu, si otú a na-emepụta dioxins. Ihe na-emetụta ihe na-agụnye ihe mkpofu, mgbasa ozi ikuku, ọkụ ọkụ, wdg. Nnyocha na-egosi na okpomọkụ kachasị mma maka ọgbọ dioxin bụ 500-800 ° C, nke a na-emepụta n'ihi ọkụ ọkụ na-ezughị ezu. Tụkwasị na nke ahụ, n'okpuru ọnọdụ okpomọkụ dị ala, n'okpuru catalysis nke metals mgbanwe, dioxin precursors na obere molecule molecule nwere ike ịmepụta site na catalysis nke obere okpomọkụ. Otú ọ dị, n'okpuru ọnọdụ ikuku oxygen zuru oke, ọkụ ọkụ na-erute 800-1100 ° C nwere ike izere ịmepụta dioxin nke ọma.

2.Ihe ize ndụ nke dioxin

Dị ka ihe na-esi na ya pụta, dioxins na-enwe nchegbu dị ukwuu n'ihi nsi ha, nnọgidesi ike na bioaccumulation. Dioxins na-emetụta nhazi nke homonụ mmadụ na ihe ndị na-ahụ maka mpaghara ụda, bụ nnukwu ọrịa carcinogenic, na-emebi usoro ahụ ji alụso ọrịa ọgụ. Nsi ya hà nhata ugboro 1,000 nke potassium cyanide na ugboro 900 nke arsenic. Edepụtara ya dị ka ọrịa carcinogen nke mmadụ dị ọkwa nke mbụ yana otu n'ime ihe mmetọ mbụ a na-achịkwa n'okpuru nkwekọrịta Stockholm na mmetọ Organic na-adịgide adịgide.

3.Usoro iji belata dioxin na Sistemụ Ininerator Gasification

Mkpọpụta anwụrụ ọkụ nke Sistemụ Ininerator Gasification nke HYHH mebere na-agbaso ụkpụrụ 2010-75-EU na China GB18485. Ọnụ ego a tụrụ atụ bụ ≤0.1ng TEQ/m³, nke na-ebelata mmetọ nke abụọ n'oge usoro mkpofu ọkụ. The Gasification Incinerator nakweere gasification + ọkụ usoro iji hụ na combustion okpomọkụ n'ime ọkụ dị n'elu 850-1100 ° C na flue gas oge obibi bụ ≥ 2 sekọnd, na-ebelata mmepụta nke dioxin si isi iyi. Akụkụ gas na-ekpo ọkụ na-ekpo ọkụ na-eji ụlọ elu na-emenyụ ọkụ ngwa ngwa belata okpomọkụ nke flue gas ruo n'okpuru 200 Celsius iji zere mmepụta nke dioxins nke abụọ na okpomọkụ dị ala. N'ikpeazụ, a ga-enweta ụkpụrụ mgbapụta dioxins.
