N'oge na-adịbeghị anya, nke mbụ Vacuum Pressure Swing Adsorption (VPSA) oxygen enrichment generator na ciment ụlọ ọrụ nke Shanghai LifenGas mepụtara bụ nke ọma nyere ọrụ maka kpọmkwem oxygen enriched combustion na ume ịzọpụta oru mmeghari ohuru nke CUCC (Ulanqab).
Mgbe arụ ọrụ kwụsiri ike nke sistemụ ahụ, ọrụ mgbanwe teknụzụ a ga-eweta uru akụ na ụba na gburugburu ebe obibi dị ịrịba ama. Ọ ga-eme nke ọma n'ịgbalite mbọ n'ichekwa coal na mbelata ikuku nke ụlọ ọrụ simenti site n'ịkwalite ọkụ ọkụ ikuku oxygen, ịba ụba ọkụ ọkụ, ibelata oriri coal, yana ibelata CO₂, NOx na ihe ndị na-esi na ya pụta.
Na Disemba 13, 2024, ụlọ ọrụ anyị bịanyere aka n'akwụkwọ nkwekọrịta na onye ahịa maka "Precise Oxygen Enriched Supporting Combustion Energy Saving Technical Transformation Project for 5000T/d Clinker Production Line of Ulanqab CUCC".
Isiokwu nke nkwekọrịta a bụ otu LVOa80 - 850 VPSA oxygen generator. A na-ezubere ya ịnye gas combustion nke ikuku oxygen na isi ụlọ ndị ahịa na akụrụngwa na-afụ ụda ọdụ, si otú ahụ nweta ihe mgbaru ọsọ nke ịchekwa coal na mbelata ikuku. Ihe ndị bụ isi teknụzụ nke generator oxygen bụ ndị a:
- Ịdị ọcha oxygen: 80% O₂ ± 2%;
- Ike: ≥850 Nm³ / h (na 0 ℃, 101.325 KPa);
- nrụgide mmepụta oxygen ngwaahịa: ≥15 KPa (nrụgide nlele).
Na Machị 19, 2025, mgbe ntọala nke akụrụngwa injinia nke ndị ahịa dị njikere maka nrụnye, ụlọ ọrụ anyị malitere ọrụ ntinye saịtị. Emechara nrụnye ahụ nke ọma n'April 14. E mesịa, n'April 15, 2025, ọrụ ahụ banyere n'ihu ọha na ntinye na ntinye ọrụ. Ka ọ na-erule Eprel 19, usoro inye ọrụ ahụ agwụla nke ọma yana igwe na-emepụta oxygen malitere inye oxygen. Ngwunye ikuku oxygen n'oge mere ka a na-arụ ọrụ na-enweghị ntụpọ nke isi kiln nke ndị ahịa na ngwá ọrụ ikuku ọdụ ọdụ.
N'oge ntinye na ntinye ọrụ, ụlọ ọrụ anyị emeghị mgbalị ọ bụla iji mee ka ọkụ eletrik dịkwuo elu ma hụ na nhazi nke ọma nke isi kiln nke onye ahịa na ihe ọkụkụ ọdụ ụgbọ mmiri, yana ọrụ nkịtị nke usoro mmepụta oxygen. N'agbanyeghị usoro ihe owuwu siri ike na ogologo oge nke obere okpomọkụ (n'okpuru 0 ℃) na mpaghara mpaghara, anyị mụbara ego anyị na-etinye n'ịrụ ụlọ na ụgwọ ọrụ iji mee ka ọganihu dịkwuo elu. N'ikpeazụ, anyị rụchara ọrụ ahụ ihe karịrị ụbọchị iri tupu oge nkwekọrịta wee malite inye gas nke ọma.
Kemgbe mmalite nke nnyefe gas, VPSA oxygen generator ejirila nkwụsi ike dị ịrịba ama na ihe ngosi ya niile agafeela nkọwapụta. Ọ na-ezute n'ụzọ zuru ezu ihe ndị ahịa chọrọ maka ịrụ ọrụ nke isi ọkụ na akụrụngwa na-afụ ọkụ, ma nweta nnukwu ego nchekwa ọkụ. Dị ka Shanghai LifenGas 'ịsụ ụzọ ikuku oxygen-eme ka ikuku combustion nlereanya oru ngo na ciment ụlọ ọrụ, ọ n'ụzọ ziri ezi na-aghọta oxygen enrichment iji nweta coal ịzọpụta na emission mbelata. Site na njirimara nke ọnụ ala dị ala, oriri ume dị ala na ikuku oxygen na-eme ka ọkụ na-eme ka ọ dịkwuo mma, ọ na-eweta uru akụ na ụba dị ukwuu na ihe nchebe gburugburu ebe obibi na ụlọ ọrụ ciment, na-enweta ihe mgbaru ọsọ nke ịchebe coal na mbelata ikuku.
