I-powder spray dryer iyinqubo yokumisa isifutho esiyisengi esivaliwe yemikhiqizo eyenziwe nge-ethanol, i-acetone, i-hexane, uwoyela wegesi nezinye izincibilikisi eziphilayo, kusetshenziswa igesi engasebenzi (noma i-nitrogen) njengendawo yokomisa.Umkhiqizo kuyo yonke inqubo awunayo i-oxidation, okuphakathi kungatholakala, futhi igesi engasebenzi (noma i-nitrogen) ingabuyekezwa kabusha.Uhlelo oluvaliwe lwe-loop oluklanyelwe ukutholwa kwe-organic solvent lunezidingo eziphakeme kakhulu zokulawula ukuqhuma kwesistimu, ukusebenza kokulawula okuzenzakalelayo kwesistimu ephezulu kakhulu, kanye nezidingo eziqinile ze-GP.Ivamise ukusetshenziswa ekumisweni kokufuthwa kwezitsha zobumba ezinembayo, imithi, izinto zebhethri, nempushana ye-carbide esimende.
I-powder spray dryer ibizwa nangokuthi uhlelo lokumisa isifutho somjikelezo ovaliwe.Isici salo ukuthi uhlelo lwakha i-loop yomjikelezo ovaliwe, futhi isithwali sokushisa singaphinda sisetshenziswe.Ukuze omiswe izinto eziguquguqukayo eziyizincibilikisi zamakhemikhali emvelo, noma izinto ezingadala ukulimala kubantu nasemvelweni ngemva kokubaleka, izincibilikisi zemvelo noma imikhiqizo equkethwe oketshezini oluphathekayo ifakwa kalula i-oxid, ivutha, futhi iziqhumane.Ngaphansi kwezimo ezijwayelekile, kuyadingeka ukusebenzisa Izinto ezikule nqubo azikwazi ukuxhumana negesi, ngakho-ke iningi labathwali bokushisa lisebenzisa amagesi angenayo (njenge-nitrogen, i-carbon dioxide, njll.).I-exhaust gas ekhishwa esomisini, ngemva kokuhlukaniswa okuqinile kwegesi, iphinde idlule ku-condenser ukuze ibuyisele isixazululi noma isuse umswakama, bese ingena ekomisweni ukuze igaywe kabusha ngemva kokushiswa yi-heater.Lolu hlobo lwesomisi ludinga ukwengeza okokusebenza kwesiqandisi ohlelweni, izindleko zokusebenza ziphezulu, futhi ukuqina komoya kwemishini kuyadingeka ukuba kube phezulu.I-powder spray dryer ngokuyinhloko inengcindezi evamile noma ingcindezi ethize ukuze kuvinjwe umoya ukuthi ungangeni ohlelweni.
Isimiso sokusebenza se-powder spray dryer:
I-powder spray dryer isebenza endaweni evaliwe, kanti indawo yokomisa igesi engasebenzi (noma i-nitrogen).Ifanele ukomisa izinto ezithile ngezincibilikisi zemvelo noma izinto ezithambekele ekubeni ne-hydrogenation ngesikhathi sokumisa;uhlelo lusebenzisa igesi ye-inert njenge-Gas ejikelezayo inomphumela wokuvikela ezintweni ezomisiwe.Igesi elijikelezayo libhekana nenqubo yokuthwala umswakama kanye nokususwa kwe-humidification, futhi okuphakathi kungasetshenziswa kabusha;i-nitrogen ifudunyezwa yi-heater bese ingena embhoshongweni wokomisa.I-powder material ezoguqulwa i-atomizer ejikelezayo enesivinini esikhulu ikhishwa ngaphansi kombhoshongo, futhi igesi ye-solvent ye-organic ehwamukile ingaphansi kwengcindezi yokucindezela okungekuhle kwefeni, futhi uthuli olufakwe kugesi luyadlula. i-cyclone separator kanye ne-spray tower.I-organic solvent gas ifinyezwa ibe uketshezi futhi ikhishwe ku-condenser, futhi i-non-condensable gas medium ishisa ngokuqhubekayo futhi igaywe kabusha ohlelweni njengesithwali esomile.
Umshini ojwayelekile wokumisa isifutho se-powder ufinyelela inhloso yokukhipha umswakama ngokuqhubekayo komoya kanye nokukhipha umoya, okubuye kube umehluko osobala phakathi kwe-powder spray dryer kanye nemishini evamile yokumisa isifutho se-centrifugal: ingaphakathi lesistimu yokomisa kuwumsebenzi wokucindezela okuhle qinisekisa Ngevelu ethile yokucindezela okuhle, uma ingcindezi yangaphakathi yehla, isidlulisi sokucindezela sizolawula ngokuzenzakalelayo ukugeleza ukuze siqinisekise ibhalansi yokucindezela kwesistimu.
