I-HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Okokuqala, ukusetyenziswa kwamandla kwimveliso yeoksijini kunye neendleko zokusebenza ziphantsi
Kwinkqubo yokuvelisa ioksijini, ukusetyenziswa kombane kubalelwa ngaphezulu kwe-90% yeendleko zokusebenza. Ngenxa yokuphuculwa okuqhubekayo kwetekhnoloji yokuvelisa ioksijini yokutsalwa koxinzelelo, ukusetyenziswa kwayo kwamandla eoksijini ecocekileyo kuye kwehla ukusuka kwi-0.45kW·h/m³ ngeminyaka yoo-1990 ukuya ngaphantsi kwe-0.32kW·h/m³ kule mihla. Kwanakwimveliso enkulu yeoksijini ekhanyayo, ukusetyenziswa kwamandla eoksijini ecocekileyo okuphantsi kumalunga ne-0.42kW·h/m³. Xa kuthelekiswa netekhnoloji yokuvelisa ioksijini ekhanyayo, itekhnoloji yokuvelisa ioksijini yokutsalwa koxinzelelo ineengenelo ezicacileyo zeendleko kwiimeko zokusebenza apho amashishini engenamfuno ye-nitrogen kwaye inkqubo yokusetyenziswa kweoksijini ayinazo iimfuno eziphezulu zokucoceka kweoksijini kunye noxinzelelo.
Okwesibini, inkqubo ilula, ukusebenza kuyaguquguquka, kwaye kulula ukuqala nokumisa
Xa kuthelekiswa netekhnoloji yokuvelisa ioksijini ekrwada, imveliso yeoksijini yokutsalwa koxinzelelo lwe-pressure swing inenkqubo elula. Izixhobo zamandla eziphambili yiRoots blower kunye neRoots vacuum pump, kwaye ukusebenza kulula kwaye kulula ukuyigcina. Ekubeni kungekho nkqubo yokupholisa okanye yokufudumeza ngexesha lokuqalisa nokuvala izixhobo zokuvelisa ioksijini yokutsalwa koxinzelelo lwe-pressure swing, ukuqalisa kokuqala kuthatha imizuzu engama-30 kuphela ukuvelisa ioksijini efanelekileyo, kwaye ukuvala kwexesha elifutshane kuthatha imizuzu embalwa kuphela ukuvelisa ioksijini. Ngaphezu koko, ukuvala isixhobo kulula, kufuna kuphela ukuvala izixhobo zamandla kunye nenkqubo yokulawula. Xa kuthelekiswa nokuveliswa kweoksijini ekrwada, itekhnoloji yokuvelisa ioksijini yokutsalwa koxinzelelo lwe-pressure swing ilula ngakumbi ukuqala nokumisa, inciphisa kakhulu iindleko zokusebenza ezifunyenwe ngexesha lokuqalisa nokuvala izixhobo.

Okwesithathu, ifuna utyalo-mali oluncinci kwaye inexesha elifutshane lokwakha
Ukuhamba kwenkqubo yesixhobo sokuvelisa ioksijini esitshintsha uxinzelelo silula, ikakhulu senziwe yinkqubo yamandla, inkqubo yokufunxa kunye nenkqubo yokutshintsha iivalvu, njl. Inani lezixhobo lincinci, nto leyo enokonga iindleko zotyalo-mali lwesixhobo kube kanye. Esi sixhobo sithatha indawo encinci, enokunciphisa iindleko zokwakha izixhobo kunye neendleko zomhlaba wokwakha. Umjikelo wokucubungula kunye nokuvelisa izixhobo umfutshane kakhulu. Umjikelo wokucubungula wezixhobo eziphambili ngokubanzi awudluli kwiinyanga ezine. Kwiimeko eziqhelekileyo, imfuneko yokuvelisa ioksijini inokufezekiswa kwisithuba seenyanga ezintandathu. Xa kuthelekiswa nexesha lokwakha eliphantse libe ngunyaka omnye lokuvelisa ioksijini ekrwada, ixesha lokwakha lesixhobo linciphile kakhulu.
Okwesine, izixhobo zilula kwaye kulula ukuzilungisa
Izixhobo ezisetyenziswa kubuchwepheshe bokuvelisa ioksijini yokutsalwa koxinzelelo lwe-pressure swing, ezifana nee-blowers, ii-vacuum pumps kunye nee-valve ezilawulwa yinkqubo, zonke zinokwenziwa ekhaya. Ukutshintshwa kweendawo ezingasetyenziswayo kulula, okunokunciphisa iindleko kwaye kwenze ixesha lokwakha libe lula ukulilawula. Ukugcinwa kwezixhobo kulula kwaye inkonzo emva kokuthengisa ilula. Xa kuthelekiswa nokugcinwa kwee-compressor ezinkulu ze-centrifugal ezisetyenziswa kwimveliso ye-oksijini e-cryogenic, abasebenzisi bemveliso yeoksijini yokutsalwa koxinzelelo lwe-pressure swing akufuneki batyale imali eninzi yolondolozo okanye baqeshe abasebenzi abaziingcali bolondolozo.

Ingongoma yesihlanu kukuba ukulawulwa komthwalo kulula
Xa kuthelekiswa netekhnoloji ye-cryogenic liquid oxygen, imveliso ye-pressure swing adsorption oxygen inokufikelela ekuhlengahlengisweni ngokukhawuleza kwemveliso kunye nobunyulu kunye notshintsho oluncinci ekusebenziseni amandla e-oxygen acocekileyo. Imveliso iyonke inokulungiswa phakathi kwe-30% kunye ne-100%, kwaye ubunyulu bunokulungiswa phakathi kwe-70% kunye ne-95%. Ingakumbi xa kusetyenziswa iiseti ezininzi zezixhobo zokuvelisa i-oxygen adsorption swing ngaxeshanye, ukulungiswa komthwalo kulula kakhulu.
Okwesithandathu, inomgangatho ophezulu wokhuseleko lokusebenza
Ngenxa yokuba ukuveliswa kweoksijini yokutsalwa koxinzelelo oluphantsi kubushushu begumbi kwaye akuyi kubakho zinto zifana nokutyetyiswa kweoksijini engamanzi kunye ne-acetylene, kukhuselekile xa kuthelekiswa nokusebenza kobushushu obuphantsi kunye noxinzelelo oluphezulu kwemveliso yeoksijini ye-cryogenic.
