HANGZHOU NUZHUO TECHNOLOGY GROUP CO., LTD.

Ua ntej, kev siv zog rau kev tsim cov pa oxygen thiab tus nqi ua haujlwm qis
Hauv cov txheej txheem tsim cov pa oxygen, kev siv hluav taws xob suav txog ntau dua 90% ntawm cov nqi khiav lag luam. Nrog rau kev ua kom zoo dua ntawm kev siv tshuab tsim cov pa oxygen siab hloov pauv, nws cov hluav taws xob siv oxygen ntshiab tau txo qis los ntawm 0.45kW · h / m ³ hauv xyoo 1990 mus rau qis dua 0.32kW · h / m ³ niaj hnub no. Txawm tias rau kev tsim cov pa oxygen cryogenic loj, kev siv hluav taws xob oxygen ntshiab qis tshaj plaws yog nyob ib puag ncig 0.42kW · h / m ³. Piv nrog cov txheej txheem tsim cov pa oxygen cryogenic, cov txheej txheem tsim cov pa oxygen siab hloov pauv muaj cov txiaj ntsig zoo hauv cov xwm txheej ua haujlwm uas cov tuam txhab tsis muaj kev xav tau nitrogen thiab cov txheej txheem siv oxygen tsis muaj qhov xav tau siab rau kev ntshiab oxygen thiab siab.
Qhov thib ob, cov txheej txheem yooj yim, kev ua haujlwm yooj ywm, thiab nws yooj yim rau pib thiab nres
Piv nrog rau kev siv tshuab ua pa oxygen cryogenic, kev tsim cov pa oxygen pressure swing adsorption muaj cov txheej txheem yooj yim heev. Cov khoom siv fais fab tseem ceeb yog Roots blower thiab Roots lub twj tso kua mis nqus tsev, thiab kev ua haujlwm yooj yim heev thiab yooj yim rau kev saib xyuas. Vim tias tsis muaj txheej txheem txias lossis cua sov thaum lub sijhawm pib thiab kaw ntawm cov khoom siv tsim cov pa oxygen pressure swing adsorption, qhov pib thawj zaug tsuas yog siv sijhawm 30 feeb los tsim cov pa oxygen tsim nyog, thiab qhov kaw luv luv tsuas yog siv sijhawm ob peb feeb los tsim cov pa oxygen. Ntxiv mus, kev kaw ntawm lub cuab yeej yooj yim dua, tsuas yog xav tau kev kaw ntawm cov khoom siv fais fab thiab kev tswj hwm. Piv nrog rau kev tsim cov pa oxygen cryogenic, kev siv tshuab tsim cov pa oxygen pressure swing adsorption yooj yim dua rau kev pib thiab nres, txo cov nqi khiav lag luam uas tshwm sim thaum lub sijhawm pib thiab kaw ntawm cov khoom siv.

Qhov thib peb, nws xav tau kev nqis peev tsawg dua thiab muaj lub sijhawm tsim kho luv luv
Cov txheej txheem ntawm lub tshuab nqus pa oxygen yog yooj yim, feem ntau yog tsim los ntawm lub zog fais fab, lub tshuab nqus pa thiab lub tshuab hloov pauv valve, thiab lwm yam. Cov khoom siv me me, uas tuaj yeem txuag tau tus nqi ib zaug ntawm cov khoom siv. Lub cuab yeej siv thaj chaw me me, uas tuaj yeem txo tus nqi tsim kho vaj tse ntawm lub cuab yeej thiab tus nqi ntawm thaj av tsim kho. Lub voj voog ua thiab tsim khoom ntawm cov khoom siv luv luv. Lub voj voog ua tiav ntawm cov khoom siv tseem ceeb feem ntau tsis pub tshaj plaub lub hlis. Nyob rau hauv cov xwm txheej ib txwm muaj, qhov xav tau tsim cov pa oxygen tuaj yeem ua tiav hauv rau lub hlis. Piv nrog lub sijhawm tsim kho yuav luag ib xyoos rau kev tsim cov pa oxygen cryogenic, lub sijhawm tsim kho ntawm lub cuab yeej raug txo qis heev.
Plaub, cov khoom siv yooj yim thiab yooj yim rau kev tswj hwm
Cov khoom siv siv rau hauv cov thev naus laus zis tsim cov pa oxygen siab, xws li lub tshuab cua, lub twj tso kua mis thiab cov qhov dej tswj hwm los ntawm kev pab cuam, tuaj yeem tsim hauv tsev. Kev hloov cov khoom seem yooj yim, uas tuaj yeem txo cov nqi thiab ua rau lub sijhawm tsim kho yooj yim tswj. Kev saib xyuas cov khoom siv yooj yim thiab kev pabcuam tom qab muag yooj yim. Piv nrog rau kev saib xyuas cov compressors centrifugal loj siv rau hauv kev tsim cov pa oxygen cryogenic, cov neeg siv cov pa oxygen siab tsis tas yuav nqis peev ntau ntawm cov nyiaj saib xyuas lossis ntiav cov neeg ua haujlwm saib xyuas kev tshaj lij.

Lub ntsiab lus thib tsib yog tias kev tswj hwm kev thauj khoom yooj yim
Piv nrog rau cov thev naus laus zis kua oxygen cryogenic, kev tsim cov pa oxygen uas siv lub zog siab hloov pauv tuaj yeem ua tiav kev hloov kho sai ntawm cov zis thiab kev huv nrog kev hloov pauv me ntsis ntawm kev siv hluav taws xob oxygen ntshiab. Cov zis dav dav tuaj yeem hloov kho ntawm 30% thiab 100%, thiab kev huv tuaj yeem hloov kho ntawm 70% thiab 95%. Tshwj xeeb tshaj yog thaum siv ntau pawg ntawm cov khoom siv tsim cov pa oxygen uas siv lub zog siab hloov pauv ua ke, kev hloov kho qhov hnyav yooj yim dua.
Rau, nws muaj qib siab ntawm kev nyab xeeb ua haujlwm
Vim tias qhov tseeb tias kev tsim cov pa oxygen los ntawm kev hloov pauv siab yog kev ua haujlwm qis-siab ntawm chav tsev kub thiab yuav tsis muaj qhov tshwm sim xws li kev nplua nuj ntawm cov pa oxygen thiab acetylene, nws muaj kev nyab xeeb dua piv rau kev ua haujlwm qis-kub thiab siab-siab ntawm kev tsim cov pa oxygen cryogenic.
