Ngwa mgbochi corrosion nke rotary kiln
Rotary kiln bụ ngwá ọrụ kachasị mkpa na ahịrị mmepụta ciment, ọrụ ya kwụsiri ike na-ejikọta ya na mmepụta na àgwà ciment clinker.Otú ọ dị, n'ime afọ ndị na-adịbeghị anya, a na-enwekarị nsogbu na shei rotary, dị ka nrụrụ, mgbawa, na ọbụna mgbaji, na-akpata nnukwu mfu ozugbo na nke na-apụtaghị ìhè, na ọbụna nsogbu nchekwa.Enwere ọtụtụ ihe kpatara nsogbu ndị a, dịkaọrụoge, ihu igwe, ọrụ onye na-arụ ọrụ, wdg Otu n'ime ihe ndị kachasị mkpa bụ corrosion nke rotary kiln cylinder, nke ga-eme ka cylinder dị ntakịrị ma belata ikike ibu, na-ebute nsogbu ndị a kpọtụrụ aha n'elu.
Ina mgbakwunye na oke okpomọkụ, a ga-emepụtakwa ikuku ụfọdụ na-emebi emebiin usoro nke calcinmbaclinker na rotary kiln, karịsịa na mmepụta ahịrị nke na-emekọ ihe mkpofu, a ga-emepụta nnukwu gas na-emerụ ahụ dị ka sọlfọ oxides, nitrogen oxides, hydroxides, chlorine, wdg..Gasị ndị a na-eji mmiri emeghachi omume n'ụzọ kemịkalụ wee mepụta ihe ndị na-akpata acid na-emebi emebi, nke ga-emebi mgbidi dị n'ime ụlọ rotary.Dị ka onye injinia nke ụlọ ọrụ ciment si kwuo, mgbidi dị n'ime nke ụlọ ọrụ rotary ụlọ ọrụ ahụ mebiri 1 mm n'ime nanị ọkara afọ.Ọ bụrụ na emeghị usoro mgbochi corrosion, ọbụlagodi igwe rotary ọhụrụ ga-enwe nsogbu mgbe ejiri ihe karịrị afọ iri.
Ihe mgbochi corrosion nke mgbidi dị n'ime nke rotary kiln nwere ike iji mkpuchi mgbochi corrosion na-eguzogide SY-elu okpomọkụ.Njirimara ngwaahịa a bụ ndị a:
1. Ihe mkpuchi ahụ dị oke, isi ike dị elu, na-eyi na-eguzogide ọgwụ na mmetụta na-eguzogide, na-eguzogide nsị site na anwụrụ ọkụ na uzuzu uzuzu;
2. Ihe mkpuchi bụ rna-eguzogide corrosion dị elu nke okpomọkụ dị ka sulfide, nitrogen oxide, HCl gas na nnu spray, na-eguzogide ọgwụ "igirigi" corrosion nke mmiri condensate, na-eguzogide ọgwụ na-agbanwe acid na alkali corrosion na usoro nke desulfurization na denitrification;
3. Ihe mkpuchi ahụ nwere ogologo ndụ ọrụ na ịdịte aka dị mma, na mkpuchi mebiri emebi dị mfe ịrụzi;
4. Ọnụ ọgụgụ dị elu nke mgbasawanye linear, ezigbo adhesion, na ike njikọ siri ike na mkpụrụ;
5. Igwe ọkụ na-ekpo ọkụ na-ekpo ọkụ dị elu, ikuku ọkụ ọkụ na-agbanwe agbanwe ma dị elu, mkpuchi adịghị adapụ, ọ dịghịkwa mgbape;
6. N'elu ihe nkiri mkpuchi ahụ dị mma, na-enwe mmetụta na-ehichapụ onwe ya na mgbochi tar.
Enwere ike ịhụ ya site na njirimara ngwaahịa na SY-elu okpomọkụ na-eguzogide ọgwụ na mgbochi corrosion abụghị nanị na-eguzogide acid, alkali na okpomọkụ dị elu, kamakwa ọ nwere ezigbo adhesion, nke kwekọrọ na itinye akwa mkpuchi mkpuchi mkpuchi. mgbidi dị n'ime nke rotary kiln, nke nwere ike iguzogide chemical napmmebi hysical, ka ọ dịchedo rotary kiln si corrosion mmebi nke acid na alkali okpomọkụ dị elu.
