Iisefu zemolekyuli zeZeolite zibalulekile{0}}kwinkqubo yokucoca yangaphambili yoshishino lokwahlula umoya we-cryogenic. Umlambo womoya kufuneka udlule kwibhedi ye-molecular sieve ngaphambi kokungena kwiyunithi yokwahlula umoya, ukususa ukungcola okunokuphazamisa inkqubo ye-cryogenic okanye kuchaphazela umgangatho wemveliso.
Yintoni iCryogenic Air Separation Technology?
Itekhnoloji yokwahlula umoya ye-Cryogenic isekelwe kumahluko kwiindawo ezibilayo zeegesi ezidibeneyo, iqala ipholisa umoya kwiqondo lokushisa eliphantsi kakhulu (elingaphantsi kwendawo yokubilisa yecandelo ngalinye legesi), ngokuqhelekileyo lingaphantsi kwe-180℃, kwaye emva koko isebenzisa umahluko wendawo yokubilisa ukukhupha kunye nokwahlula iigesi.
Itekhnoloji yokwahlula umoya we-Cryogenic isetyenziswa ngokubanzi kwintsimbi, iikhemikhali, i-elektroniki, unyango, i-aerospace kunye nezinye iinkalo. Yeyona ndlela iphambili yokwahlula igesi yeshishini, kwaye ngoku yeyona ndlela ivuthiweyo nesebenzayo yokuvelisa ioksijini, initrogen, iargon kunye neegesi ezinqabileyo.
Inkqubo yokwahlulwa koMoya yeCryogenic Distillation
Inkqubo yokwahlula umoya weCryogenic distillation ihlala ibandakanya la manyathelo mathandathu alandelayo:
Uxinzelelo lomoya: Uxinzelelo lomoya ngezigaba ezininzi zecompressor, ukubonelela ngoxinzelelo oluyimfuneko lokupholisa umoya kunye nokwahlula okulandelayo. Uluhlu loxinzelelo lunokuba yi-0.5Mpa ~ 0.8Mpa (isixhobo esiqhelekileyo soxinzelelo), okanye i-3Mpa ~ 6Mpa (isixhobo soxinzelelo oluphezulu).
Ngaphambi{0}}ukupholisa: Yehlisa ubushushu bomoya ukuya kwindawo yokuntywila ngento epholileyo (idla ngokuba ngamanzi okupholisa okanye ifriji), malunga ne-5℃ukuya kwi-10 degree, ukunciphisa imfuno yamandla yokwahlukana komoya okulandelayo.
{0}}Ukuhlanjululwa: Sebenzisa iinqaba ze-adsorption (ezilayishwe ngeesefu zemolekyuli, i-alumina evuliweyo kunye nezinye ii-adsorbents) ukususa ubumdaka obufana nokufuma, ikharbon diokside kunye ne-hydrocarbons, ukuthintela umkhenkce ophantsi{1}}wobushushu kunye nokuvala izixhobo, uqinisekisa ukhuseleko lwenkqubo ye-cryogenic.
Ukupholisa okunzulu: Umoya ocociweyo utshintshisa ubushushu kunye nokuhamba komoya obandayo, ngokuthe ngcembe upholisa ukuya kutsho kwiqondo lobushushu obunyibilikayo, malunga ne- -170℃ukuya kwi -180℃, kwaye enye igesi esemoyeni iyanyibilika.
Ulwahlulo lweDistillation: Uluhlu loxinzelelo oluphezulu lwahlula ngaphandle ioksijini{0}ulwelo olutyebileyo kunye nenitrogen{1}}etyebileyo yolwelo. Okuphezulu-ioksijini ecocekileyo kunye nenitrogen zifumaneka kwikholamu yoxinzelelo oluphantsi emva kwedistillation eyongezelelekileyo. Kwaye igesi ye-argon iholwa phakathi kwekholamu yoxinzelelo oluphantsi.
Gas extraction and storage: Oxygen, nitrogen and argon are reheated to gas and and then output. Some are liquefied for storage, such as liquid oxygen and liquid nitrogen. However, high purity oxygen (>99.5%), nitrogen (>99.9%), and argon (>99.9%) ziyafumaneka xa ziceliwe.
I-Sieves ye-Molekyuli yoKwahlula i-Cryogenic Air
13X-APG Zeolite Molecular Sieve: Iphuhliswe ngokukodwa kwishishini lokwahlula umoya we-air cryogenic, esebenza nakuwuphi na ubungakanani bezixhobo zokwahlula{2}}izixhobo zokwahlula{3}}X{4}}I-APG inomthamo owomeleleyo wokukhetha amanzi kunye necarbon dioxide.
I-13X -I-HP Zeolite ye-Molecular Sieve: Inokusebenza okuphezulu kwe-oksijini kunye ne-nitrogen kunye nesantya esaneleyo sokuvelisa i-oksijini, esetyenziswa kakhulu kwiiyunithi ezivelisa i-oksijini ukuphumeza ukwahlukana kwe-oksijini kunye ne-nitrogen, ukwenza i-oksijini yezoshishino kunye nezonyango.
13X-APG{2}}III Zeolite Molecular Sieve: Ludidi oluphambili lwe-13X-APG. Ukusebenza kwe-adsorption ye-zeolite 13X{7}}APG{8}}III yi-60% ~ 70% ngaphezulu kwaleyo ye-13X-APG. Naphantsi kweemeko zekharbon diokside, umthamo we-adsorption we-13X{15}}APG{16}}III usaqhuba kakuhle.
13X-APG{2}}V Zeolite Molecular Sieve: I-adsorption performance ye-13X{4}}APG{5}}V ingaphezulu kwe-13X{7}}APG, kwaye ngaphezulu kwe-1.4 amaxesha 13X-APG{11}}III{12}}X{13}}APG{14}}Isihluzo se-molekyuli ye-V sisixhobo esikhokelayo kushishino lokwahlula umoya we-cryogenic, kwaye izalathisi zayo zokusebenza zingaphezulu lee kunezandulelayo.
