Iskimu sokuziswa kwekhabhoni esebenzayo
Iimpawu zezinto eziphathekayo
Ikhabhoni esebenzayo yikhabhoni ephathwe ngokukodwa efudumeza izinto eziphilayo (amaqokobhe amalahle, amalahle, iinkuni, njl.njl.) xa kungekho moya wokunciphisa amacandelo angengawo-carbon (le nkqubo ibizwa ngokuba yi-carbonization), kwaye emva koko isabela ngegesi, kwaye umphezulu wogqunywe ngumoya.Ukhukuliseko, olukhokelela kwisakhiwo se-microporous (le nkqubo ibizwa ngokuba yi-activation).Kuba inkqubo yokuvula yinkqubo ye-microscopic, oko kukuthi, ukukhukuliseka komphezulu inani elikhulu le-molecular carbides kukukhukuliseka kwamanqaku, ngoko ke umphezulu wekhabhoni osebenzayo unemingxuma emincinci emininzi.Uninzi lweedayamitha ze-micropore kumphezulu wekhabhoni esebenzayo ziphakathi kwe-2 kunye ne-50 nm.Nokuba isixa esincinci sekhabhoni esebenzayo inommandla omkhulu womphezulu.Indawo engaphezulu yegram nganye yekhabhoni esebenzayo yi-500 ukuya kwi-1500 m2.Phantse zonke izicelo zekhabhoni esebenzayo zisekwe kolu phawu lwekhabhoni esebenzayo.
Iingxaki zemveliso
1. Ukucocwa kwekhabhoni esebenzayo yinkqubo yonyango oluphezulu, oludla ngokuqwalaselwa kuphela xa izikhombisi zomgangatho wamanzi zamanzi amdaka zisengakwazi ukuhlangabezana neemfuno zokukhupha emva kokuba amanzi amdaka ecocwe ngezinye iinkqubo eziqhelekileyo.
2. Ngaphambi kokuba uthathe isigqibo sokukhetha inkqubo yekhabhoni esebenzayo, ukungcola kwenkqubo yangaphambili yonyango okanye iisampulu zamanzi ezinomgangatho ofanayo wamanzi kufuneka zisetyenziswe kuvavanyo lwekholomu yekholomu, kunye nekhabhoni esebenzayo yeempawu ezahlukeneyo kunye neenkcukacha kufuneka zihlolwe, kwaye ke iiparamitha zoyilo eziphambili, ezifana nokuhluzwa kwamanzi, kufuneka zifunyenwe ngovavanyo.isantya, umgangatho wamanzi amdaka, umjikelo wokuzalisa, umjikelo omfutshane wokuhlamba umva, njl.
3. Amanzi anempembelelo yenkqubo yekhabhoni esebenzayo kufuneka ahluzwe kuqala ukukhusela umphezulu wekhabhoni ukuba uvalwe ngenxa yobuninzi bezinto eziqinileyo ezimisiwe.Ngexesha elifanayo, ukuxinwa kwezinto eziphilayo kumanzi achaphazelekayo akufanele kube phezulu kakhulu ukuphepha ukugcwala ngokugqithiseleyo kwekhabhoni esebenzayo, ukwenzela ukuba kuqinisekiswe umjikelezo wokuhlaziya ofanelekileyo kunye neendleko zokusebenza.Xa i-CODc yoxinaniso lwamanzi anempembelelo idlula i-50-80 mg / L, inkqubo ye-biological activated carbon kufuneka iqwalaselwe ngokubanzi unyango.
4. Ukulungiswa kwamanzi abuyiselwe okanye ezinye iinkqubo zonyango apho ukuxinwa kwezinto ezingcolileyo ezidlula umgangatho zihlala zitshintsha, iyunithi yokucoca i-carbon activated kufuneka ixhotyiswe ngombhobho we-spanning okanye we-bypass.Iyunithi yekhabhoni esebenzayo, enokugcina umthamo we-adsorption webhedi yekhabhoni esebenzayo kwaye yandise ngokufanelekileyo ixesha lokuhlaziya okanye ukutshintshwa.
5. Xa usebenzisa ibhedi esisigxina, cinga ukuyila i-pool yokuphumla okanye i-carbon tower ngokokuhlaziywa okanye ukutshintshwa komjikelo wekhabhoni esebenzayo.Iibhedi eziziimobhayili kufuneka ziqwalaselwe kwakhona xa kukho imfuneko.
6. Ekubeni ukudibanisa phakathi kwekhabhoni esebenzayo kunye nentsimbi eqhelekileyo kuya kubangela ukubola okukhulu kwe-electrochemical, isakhiwo sekhonkrithi esomeleziweyo okanye insimbi engenasici, iplastiki kunye nezinye izinto kufuneka ziqwalaselwe kuqala xa kuyilwa isixhobo sonyango lwekhabhoni.Ukuba i-carbon steel eqhelekileyo isetyenzisiweyo, indawo yangaphakathi yesixhobo kufuneka ifakwe kwi-epoxy resin, kwaye ubukhulu be-lining kufuneka bube bukhulu kune-1.5mm.
7. Xa usebenzisa umgubo wekhabhoni, qwalasela ukhuseleko lomlilo nogqabhuko-dubulo, kwaye izixhobo zombane ezisetyenziswayo nazo ziyahlangabezana neemfuno zokumelana nokudubula.
Sebenzisa izixhobo
I-vacuum feeder (kuba i-carbon powder powder esebenzayo ilungile, izinto eziphathekayo kunye nobuhle besici sokucoca kufuneka kuthathelwe ingqalelo).
