Na-arị elu nke ọma, VPSA (obere nrụgide adsorption vacuum desorption) mmepụta oxygen bụ "iche" ọzọ nke.PSA mmepụta oxygen, ụkpụrụ mmepụta oxygen ha fọrọ nke nta ka ọ bụrụ otu, na ngwakọta gas na-ekewa site na ọdịiche dị na ike nke sieve molecular na "adsorb" dị iche iche gas molecules.Mana usoro mmepụta oxygen PSA bụ site na mgbasa ozi nrụgide, nrụpụta ikuku ikuku iji kewaa oxygen.Usoro VPSA nke mmepụta ikuku oxygen bụ iji mebie sieve molekul juru n'okpuru ọnọdụ agụụ.
Ọ bụ ezie na ha abụọ dabere na ikuku dị ka akụrụngwa, ụkpụrụ nke mmepụta oxygen yiri ya.Ma n'iji nlezianya tụnyere, enwere ọdịiche ndị a;
1. NkeVPSA oxygen generatorna-eji ihe na-afụ ụfụ iji nweta ikuku dị ndụ ma na-amanye ya, ebe PSA oxygen generator na-eji ikuku compressor na-enye gas.
2, Na isi akụrụngwa - zeolite molecular sieve nhọrọ, PSA oxygen generator na-eji sodium molecular sieve na VPSA oxygen generator na-eji lithium molecular sieve.
3. The adsorption mgbali nke PSA oxygen generator na-emekarị 0.6 ~ 0.8Mpa, na adsorption mgbali nke VPSA oxygen generator bụ 0.05Mpa na desorption mgbali bụ -0.05Mpa.
4, PSA otu osisi gas mmepụta ikike nwere ike iru 200 ~ 300Nm³ / h, na VPSA otu osisi gas mmepụta ike nwere ike iru 7500 ~ 9000Nm³ / h.
5, VPSA ikwu PSA, bụ obere ike oriri (mmepụta nke 1Nm3 oxygen oriri ike ≤ 0.31kW, oxygen ọcha 90%, na-enweghị oxygen mkpakọ), na ndị ọzọ gburugburu ebe obibi enyi na enyi.
6, Dabere na mmepụta oxygen, ụkpụrụ oriri ike na itinye ego na nhọrọ PSA ma ọ bụ usoro VPSA.
VPSA oxygen generator ọ bụ ezie na otu osisi oxygen mmepụta ikike dị ukwuu, ma ya erughi bụ na usoro akụrụngwa bụ ihe mgbagwoju anya, olu nke ngwá bụ ibu (tụnyere na cryogenic ngwaọrụ ka obere), na-akwado na utilities ọnọdụ ndị ọzọ chọrọ. , ga-ejigide ohere buru ibu, n'ozuzu enweghị ike ịme ụdị akpa.Ma ọ chọrọ nrụnye na saịtị, inye ọrụ, site na nke a naanị.PSA nwere ụfọdụ uru.
