Iingcebiso ezi-2 zokwandisa ubomi be-molecular sieves

I-molecular sieve, ngenxa yomthamo wayo oqinileyo we-adsorption kunye nokumelana nobushushu obuphezulu, isetyenziswa ngokubanzi kumashishini amaninzi.Iisefu ezisetyenziswa ngokuqhelekileyo zemolekyuli eziveliswa nguJXKELLEYzi-3A, 4A, 5A, 13X kunye nezinye iintlobo ze-molecular sieves.Ngoko indlela yokwandisa ubomi benkonzo ye-molecular sieve ngokusebenzisa iindlela ezi-2?
1. Sebenzisa okusingqongileyo
1. Indawo yokusetyenziswa kwe-molecular sieve ihambelana nokufuma kwayo kokusingqongileyo, uxinzelelo lwesilingo, ukuxinana kokuzalisa, njl. Ingasetyenziselwa iminyaka eyi-2-3 phantsi kweemeko eziqhelekileyo.Ukuba indawo yokugcina ilungile, kwaye akukho ngozi yokuvelisa, ixesha layo lokuphila lingasetyenziselwa iminyaka engaphezu kwe-5.
2. Izisefu ezintsha zemolekyuli, ngaphandle kokuba kuboniswe ngokucacileyo ukuba zenziwe zasebenza zaza zatywinwa.Ngaphandle koko, kusafuneka ukuba isebenze ngokubhaka okuphezulu kweqondo lokushisa, ngokubanzi i-500 degrees yanele.Ukuqaliswa kuqhutyelwa kwisithando somlilo se-muffle.Kungcono ukudlulisa umoya we-cylinder okanye i-nitrogen kwisithando somlilo, kwaye emva koko uphole ngokwemvelo malunga ne-100 degrees phantsi kweemeko zomoya, uyikhuphe kwaye uyidlulisele kwi-desiccator yokugcina umoya.
2. Indlela yokusebenzisa
1. Ukusetyenziswa ngokuchanekileyo kwesefa yemolekyuli.Ngexesha lokusebenza, kufuneka sisebenze ngokungqongqo ngokuhambelana nexabiso loyilo lwezixhobo ze-adsorption, kwaye silandele ngokungqongqo izikhombisi eziphambili ezifana nezinga lokuhamba, ubushushu, uxinzelelo, ixesha lokutshintsha lokutya okubekwe yinkqubo.Ixabiso elimiselweyo alinakutshintshwa ngaphandle kwesizathu.Isixhobo se-molecular sieve adsorption kunye noyilo olufanelekileyo kunye nokusetyenziswa okufanelekileyo kufuneka kusetyenziswe iiyure ezingama-24'000-40'000, malunga ne-3 ukuya kwiminyaka emi-5.

2. I-molecular sieve esemgangathweni inokunciphisa kakhulu umthamo wamanzi emoyeni, ithintele ukungcoliswa kweoli yokuthambisa, ukufudumeza okuchanekileyo kunye nokuvuselelwa, kunye nokususa umgubo ngexesha.Ukongezelela, kwinkqubo yokuvuselela i-molecular sieve, kukulungele ukusebenzisa imveliso yegesi eyomileyo ephathwa nge-molecular sieve okanye i-low dew point gas yezinye iinkqubo, kwaye akufanelekanga ukusebenzisa umoya wokushisa kwegumbi ukuvuselela i-molecular sieve bed.
3. Kwinqanaba lokupholisa, nikela ingqalelo ekusebenzeni okufanelekileyo.Ukufudumeza kwinkqubo yokuvuselela kufuneka kuqhutywe ngokukhawuleza kwizigaba kwaye akukwazi ukufudumeza ngokuthe ngqo kwi-200-300 degrees.Umbhede we-molecular sieve uhlaziywe ngokuthe ngqo, kwaye igesi yokuvuselela kufuneka ihlale malunga ne-150 degrees xa ifudumala.Ixesha lokufudumeza kunye nokuvuselelwa kwakhona liyingongoma ebalulekileyo efanelwe ingqalelo.

Indlela yokugweba ukuba i-molecular sieve kwifektri ifuna ukutshintshwa?Ngokubanzi, sinokujonga ukuba iphelelwe lixesha ngokwemiyalelo yokusetyenziswa.Ukuba iphelelwa lixesha, kufuneka itshintshwe.Ukuba i-molecular sieve ingene emanzini, kufuneka itshintshwe nangaliphi na ixesha.Emva kokucwiliswa kwamanzi, nangona ukuvuselelwa okukhethekileyo kusetyenziswa, i-sieve ye-molecular iya kuba phantsi kwempembelelo yomoya.Ukukhokelela ekwaphuleni, kulula ukuvimba umtshintshi wobushushu, kwaye ukugcinwa okulandelayo kuyinkathazo.Ngexesha elifanayo, kuxhomekeke ekubeni umswakama kunye nomxholo we-carbon dioxide wegesi ecocekileyo ungaphakathi kwesalathisi.Ukuba idlula isalathisi, kufuneka itshintshwe ngokukhawuleza.Kuphela ngokukhetha indawo efanelekileyo yokusebenza, kunye nokugcinwa kunye nokugcinwa, ngaba ubomi bayo benkonzo bunokwandiswa ngokufanelekileyo.
