Nitrogen na-eme molekụla sieve

N'ime ụlọ ọrụ mmepụta ihe, a na-ejikarị generator nitrogen eme ihe na petrochemical, gas liquefaction, metallurgy, food, pharmaceutical and electronics industry. Enwere ike iji ngwaahịa nitrogen nke generator nitrogen dị ka ngwá ọrụ gas, kamakwa dị ka akụrụngwa mmepụta ihe na refrigerant, nke bụ ngwá ọrụ ọha na eze dị mkpa na mmepụta mmepụta ihe. Usoro nke nitrogen generator bụ tumadi kewara ụzọ atọ: miri oyi ikuku nkewa usoro, akpụkpọ ahụ nkewa usoro na molekụla sieve mgbali mgbanwe adsorption usoro (PSA).
Usoro nkewa nke ikuku oyi dị omimi bụ iji usoro isi ihe dị iche iche nke ikuku oxygen na nitrogen na ikuku, na mmepụta nke nitrogen mmiri mmiri na ikuku oxygen site na ụkpụrụ nke mkpakọ, refrigeration na obere okpomọkụ distillation ". Usoro a nwere ike ịmepụta obere okpomọkụ nitrogen mmiri mmiri na mmiri mmiri oxygen, nnukwu mmepụta ọnụ ọgụgụ; mwepu bụ nnukwu ego, nke a na-ejikarị na nitrogen na ikuku oxygen na metallurgy na ụlọ ọrụ kemịkalụ.
Usoro nkewa nke membrane bụ ikuku dị ka ihe eji eme ihe, n'okpuru ọnọdụ nrụgide ụfọdụ, na-eji oxygen na nitrogen na akpụkpọ ahụ nwere ọnụ ọgụgụ dị iche iche nke permeability iji mee ka ikuku oxygen na nitrogen kewapụ?. Usoro a nwere uru nke dị mfe Ọdịdị, ọ dịghị ịmafe valvụ, obere olu, wdg, ma n'ihi na akpụkpọ anụ ihe tumadi na-adabere na mbubata, nke ugbu a price bụ oké ọnụ na penetration ọnụego bụ ala, n'ihi ya, ọ na-bụ-eji maka pụrụ iche nzube nke. obere eruba, dị ka mobile nitrogen eme igwe.
Molecular sieve pressure adsorption method (PSA) bụ ikuku dị ka akụrụngwa, carbon molecular sieve dị ka adsorbent, ojiji nke mgbali adsorption ụkpụrụ, ojiji nke carbon molekul sieve maka oxygen na nitrogen adsorption na oxygen na nitrogen nkewa usoro ". Usoro a nwere njirimara nke usoro nhazi dị mfe, ọkwa dị elu nke akpaaka, obere ike oriri na ịdị ọcha nitrogen dị elu, ọ bụkwa nkà na ụzụ a na-ejikarị eme ihe. Tupu ikuku abanye n'ụlọ elu adsorption mmadụ, mmiri dị n'ikuku aghaghị ịmịkọrọ iji belata nsị mmiri na sieve molecular ma gbasaa ndụ ọrụ nke sieve molecular. N'ime usoro mmepụta nitrogen PSA a na-ahụkarị, a na-ejikarị ụlọ elu ihicha wepụ mmiri dị n'ikuku. Mgbe ụlọ elu ihicha jupụtara na mmiri, a na-eji ikuku kpọrọ nkụ kụghachite ụlọ elu ihicha iji ghọta mmeghari nke ụlọ elu ihicha.
