Ikpe |Kedu otu esi eji ihe mkpuchi na-enweghị mmanụ na ndị na-ekpo ọkụ centrifugal maka mgbanwe nchekwa ike na ụlọ ọrụ ciment?
Nkà na ụzụ denitrification SCR, ya bụ, usoro mbelata catalytic ahọpụtara, a na-efesa gas amonia n'ime ngwaọrụ denitrification flue gas dị elu dị ka onye nnọchi anya denitrification.N'okpuru ọrụ nke ihe mkpali, NOx dị na flue gas na-emebi ka ọ bụrụ N₂ na H₂O na-adịghị egbu egbu na enweghị mmetọ.Na ngwaọrụ SCR ji esi mmiri ọkụ na-arụ ọrụ, denitrification ọnụego ruru 80-90%, na mgbapụ amonia dị n'okpuru 3 mg/Nm³, nke dabara nnọọ na n'ihu elu denitrification arụmọrụ chọrọ nke osisi ciment.
① A na-eziga amonia mmiri mmiri site na gwongworo mmiri mmiri amonia na tankị nchekwa mmiri amonia site na compressor na-ebupụ.
② Mgbe evaporating n'ime amonia na evaporation tank, ọ na-abanye na mmiri ọkụ ebe site amonia buffer tank na njem pipeline.
③ Mgbe evenly agwakọta na ikuku, ọ na-abanye na SCR reactor site na nkesa pilot valvụ maka esịtidem mmeghachi omume.A na-etinye reactor SCR n'ihu ikuku preheater, na gas amonia dị n'elu SCR reactor.
④ Gwakọta anwụrụ ọkụ nke ọma site na ngwaọrụ ịgbasa pụrụ iche
⑤ Mgbe agwakọtachara, flue gas na-agafe n'okirikiri ihe na-emepụta ihe na reactor maka mmeghachi omume mbelata.
Ikuku compressor ikuku soot ịfụ teknụzụ
Mgbe ị na-ahọrọ usoro ịfụ ụfụ soot, na mgbakwunye na mmetụta nsị nke soot, a ga-atụlekwa mmetụta na-eyi ihe na-eme ka ọ dịkwuo mma.Ka ọ dị ugbu a, ụzọ ịfụ ụfụ nke na-akpali akpali nke a na-ejikarị na sistemu denitration SCR gụnyere ịfụ ụda sonic soot, uzuoku soot ịfụ na ikuku soot abịakọrọ.
Ejikọtara ya na njirimara nke anwụrụ ọkụ ciment kiln na uzuzu, ọ na-esiri ike maka ndị na-afụ ụfụ sonic soot ime mgbanwe na nnukwu ego na nnukwu viscosity nke ciment kiln flue gas ájá.Tụkwasị na nke ahụ, mmepụta gas na-emepụta gas na ụlọ ciment dị ntakịrị, n'ihi ya, ọ ka mma iji ikuku abịakọrọ na-agbapụta soot.
N'ime afọ ndị na-adịbeghị anya, site na nkwalite na mmepe nke ụlọ ọrụ ciment n'ihe gbasara nchekwa gburugburu ebe obibi, ụkpụrụ ikuku na-ebuliwanye elu.Mgbochi na njikwa nke mmetọ ikuku na mbelata flue gas ikuku nitrogen oxide abụrụla ọrụ dị ngwa nke ụlọ ọrụ mmepụta ciment chere ihu.Teknụzụ SCR (Catalytic Reduction) nwere arụmọrụ denitrification dị elu ma nwee ike nweta ihe ọkụkụ dị ala nke flue gas nitrogen oxides na mgbapụ amonia n'okpuru ọnọdụ nke oriri amonia dị ala.N'ime afọ ndị na-adịbeghị anya, teknụzụ ciment kiln flue gas SCR nwekwara ọganihu ụfọdụ, na-enye nkwa dị irè maka ụlọ ọrụ ciment iji nweta ihe ọkụkụ dị ala.
