Iimpawu zemveliso ye-PSA nitrogen generator

Ngokukhula ngokukhawuleza kweshishini, i-nitrogen isetyenziswe ngokubanzi kwiikhemikhali, i-electronics, isinyithi, ukutya, oomatshini, njl njl. Imfuno ye-nitrogen kwilizwe lam iyanda ngesantya esingaphezu kwe-8% ngonyaka.I-nitrogen ayisebenzi kwiikhemikhali, kwaye ayisebenzi kakhulu phantsi kweemeko eziqhelekileyo, kwaye akukho lula ukusabela ngokwekhemikhali kunye nezinye izinto.Ke ngoko, initrogen isetyenziswa ngokubanzi njengerhasi yokukhusela kunye negesi yokutywina kwishishini lesinyithi, ishishini lombane, kunye neshishini lemichiza.Ngokuqhelekileyo, ukucoceka kwegesi ekhuselayo yi-99.99%, kwaye ezinye zifuna i-nitrogen ecocekileyo engaphezulu kwe-99.998%.Initrogen yolwelo ngumthombo obandayo olungele ngakumbi, kwaye isetyenziswa kakhulu kushishino lokutya, ishishini lezonyango, kunye nokugcinwa kwamadlozi emfuyo.Kwimveliso ye-synthetic ammonia kushishino lwesichumisi sekhemikhali, ukuba igesi ekrwada ye-synthetic ammonia-i-hydrogen kunye ne-nitrogen yegesi edibeneyo ihlanjwe kwaye ihlanjululwe nge-nitrogen ecocekileyo yolwelo, umxholo wegesi ye-inert unokuba mncinci kakhulu, kunye nomxholo wesulfure. i-monoxide kunye ne-oksijini ayidluli i-20 ppm.

I-nitrogen ecocekileyo ayinakutsalwa ngokuthe ngqo kwindalo, kwaye ukuhlukana komoya kusetyenziswa ikakhulu.Iindlela zokwahlula umoya zibandakanya: indlela ye-cryogenic, indlela yokuguqula uxinzelelo lwe-adsorption (PSA), indlela yokwahlukana kwe-membrane.

Intshayelelo kwinkqubo kunye nezixhobo ze-PSA nitrogen generator

Intshayelelo yokuhamba kwenkqubo

Umoya ungena kwi-compressor yomoya emva kokususa uthuli kunye nokungcola komatshini ngokusebenzisa isihluzo somoya, kwaye uxinzelelwe kuxinzelelo olufunekayo.Emva kokucocwa ngokungqongqo, ukucocwa kwamanzi, kunye nokususa uthuli unyango lokucocwa, umoya ococekileyo ocinezelweyo uyaphuma ukuqinisekisa ukusetyenziswa kweesefu zemolekyuli kwinqaba ye-adsorption.ubomi.

Kukho iinqaba ezimbini ze-adsorption ezinesefa ye-carbon molecular.Xa enye inqaba isebenza, enye inqaba ithotywa ukuze idesorption.Umoya ococekileyo ungena kwi-adsorption tower esebenzayo, kwaye xa udlula kwi-molecular sieve, i-oksijini, i-carbon dioxide kunye namanzi zibhengezwa yiyo.Irhasi equkuqela ukuya ekupheleni i-nitrogen kwaye ilandele izixa ze-argon kunye ne-oxygen.

Enye inqaba (i-desorption tower) yahlula i-oksijini ye-adsorbed, i-carbon dioxide kunye namanzi kwi-pores ye-molecular sieve kwaye iyikhuphe emoyeni.Ngale ndlela, ezi nqaba zimbini ziqhutywa ngokutshintshana ukugqiba ukwahlukana kwenitrogen kunye neoksijini kwaye ngokuqhubekayo imveliso yenitrogen.Ukucoceka kwenitrogen eveliswa yi-pressure swing (_bian4 ya1) i-adsorption yi-95% -99.9%.Ukuba ucoceko oluphezulu lwenitrogen luyafuneka, izixhobo zokucoca initrogen kufuneka zongezwe.

I-95% -99.9% yemveliso yenitrogen evela kuxinzelelo lwe-adsorption ye-nitrogen generator ingena kwisixhobo sokucoca initrogen, kwaye kwangaxeshanye isixa esifanelekileyo se-hydrogen songezwa nge-flowmeter, kunye ne-hydrogen kunye ne-oksijini yokulandelela kwi-nitrogen zisabela ngokufanelekileyo kwi-nitrogen. inqaba ye-deoxygenation yezixhobo zokucoca ukususa I-oksijini ke ipholiswe yi-condenser yamanzi, i-separator yamanzi e-steam ihlanjululwa ngamanzi, kwaye emva koko yomiswe ngokunzulu ngesomisi (iinqaba ezimbini zokumisa i-adsorption zisetyenziswa ngokuhlukileyo: enye isetyenziselwa i-adsorption kunye ukomisa ukususa amanzi, enye ifudunyezwa ukuchithwa kunye ne-drainage ukufumana i-nitrogen ephezulu yokucoceka kunokufikelela kwi-99.9995%.
