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. Ngethuba 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-sieve ye-molecular esemgangathweni inokunciphisa kakhulu umthamo wamanzi emoyeni, ukuthintela 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.
