Ⅰ. Ukomisa ngeConvection
Kwizixhobo zokomisa, olona hlobo luxhaphake kakhulu lwezixhobo zokomisa sisisomisi sokuhambisa ubushushu. Umzekelo,ukomisa umoya oshushu, umoya oshushu kunye noqhagamshelwano lwempahla yokutshintshiselana kobushushu ukwenzela ukuba umswakama ube ngumphunga. Iindidi eziqhelekileyo zezixhobo zokomisa i-convection zizixhobo zokumisa umoya, njengezomisi zebhedi ezimanzi, i-flash dryers, i-air dryers, i-spray dryer, i-ventilation dryer, i-flow dryers, i-air flow rotary dryer, i-dryer dryer, i-parallel flow dryers.izomisi ezijikelezayokwaye nangokunjalo.
Kwisicelo esisebenzayo, kukho oomatshini ababodwa abasetyenziswayo kunye noomatshini abadibeneyo abasetyenziswayo. Isomisi sokuhamba komoya, isisomisi sebhedi esimanzi, isitshizi sokutshiza, njl.
Ukomisa i-powder, i-granule kunye ne-flake materials, indlela eqhelekileyo kukusebenzisa umoya oshushu okanye ukuhamba kwegesi kumphezulu we-granule, kunye nokudlulisa ubushushu kwizinto eziphathekayo nge-airflow ukukhupha amanzi. Umphunga wamanzi ophuphumayo uya ngqo emoyeni kwaye uyathathwa. Imithombo yeendaba yokomisa esetyenziswa ngokuqhelekileyo kwinkqubo yokomisa i-convection ngumoya, i-inert gas, igesi yokutsha ngokuthe ngqo okanye i-steam eshushu kakhulu.
Indlela yenza umoya oshushu udibanise ngokuthe ngqo kwizinto eziphathekayo kwaye isuse umswakama ngelixa ufudumeza. Into ephambili kukuphucula indawo yoqhagamshelwano phakathi kwezinto kunye nomoya oshushu ukukhusela ukuphambuka komoya oshushu. Ubushushu bezinto eziphathekayo ngexesha lokoma kwe-isokinetic buphantse bufane nobushushu bebhalbhu emanzi yomoya oshushu, ngoko ke ukusetyenziswa komoya oshushu oshushu kunokomisa izinto ezingeva lubushushu. Le ndlela yokomisa inezinga eliphezulu lokumisa kunye nexabiso eliphantsi lezixhobo, kodwa ukusebenza kakuhle kwe-thermal kuphantsi, oku kulandelayo yimeko esisiseko yezixhobo zokomisa ezininzi zokuhambisa:
(1)Isixhobo esomisa umoya
Yenza umphezulu webhloko okanye izinto eziye zadibana nemilo esisigxina kunye nomoya oshushu. Izinga lokumisa liphantsi, kodwa uluhlu lwesicelo lubanzi.
(2)Isixhobo esomisa ibhedi esilulwelo
Vumela umoya oshushu uvuthe ngokulinganayo ukusuka ngaphantsi koluhlu lwepowder kunye nezixhobo ze-granular kwaye wenze ukuba zihambe, ukwenzela ukuba izinto eziphathekayo ziya kuxutywa ngamandla kwaye zihlakazwe. Izinga lokumisa liphezulu.
(3)Isixhobo sokomisa umoya
Le ndlela yenza ukuba umgubo usasazwe kubushushu obuphezulu bomoya oshushu kwaye udlulise izinto ngelixa usomisa. Lo mzekelo unexesha elifutshane lokumisa kwaye ufanelekile ukuphatha izinto ngobuninzi. Ukuba izinto eziphathekayo kwi-dryer ngaphambi kokusebenzisa iindlela zoomatshini zokususa amanzi amaninzi ngaphambi kokungena kwi-air dryer kunoqoqosho ngakumbi.
(4) Isitshizi sokutshiza
Ukuze isisombululo okanye izinto eziludaka kwiqondo lobushushu eliphezulu atomization umoya oshushu, amathontsi awela ngaxeshanye omiswe ngoko nangoko. Le ndlela yokumisa ixesha lifutshane, ifanelekile kwimveliso yobuninzi, kumachiza, i-punch, i-dayi yokumisa.
(5) Isomisi se-cylinder ejikelezayo
Yenza umgubo, ibhloko, izinto eziludaka ngokusebenzisa igubu elijikelezayo lidibana nomoya oshushu. Le ndlela ifanelekile kwimveliso yobuninzi. Emva kokumisa izinto zodaka zingakhutshwa njengezinto zegranular, ezininzi ezomileyo ezinokumelana nobushushu obuphezulu zisetyenziswa ngale ndlela.
(6) isixhobo sokomisa umbane
Izinto eziphathekayo zixutywe yi-high-speed ejikelezayo ejikelezayo ejikelezayo, ukwenzela ukuba ihlakazeke kwintshukumo ejikelezayo yomlambo wegesi ngexesha lokumisa. Ngokuqhelekileyo iyasebenza ekomisweni kwezinto eziphakathi, ezisetyenziselwa ukomisa izinto zokunamathisela.
Ⅱ. Ukwenza ukomisa
Ukomisa ukuqhutywa kukulungeleka kakhulu kumasuntswana afumileyo, kwaye izixhobo zokomisa izixhobo zinomgangatho ophezulu we-thermal. Umphunga wamanzi ophuphumayo utsalwa nge-vacuum okanye ukhutshwe yi-airflow, eyona nto ithwala ukufuma, kunye nokusebenza kwe-vacuum kunconywa kwizinto eziphathekayo ze-granular. Kwizixhobo zokomisa i-conduction, i-paddle dryer isetyenziselwa ukomisa izinto zokuncamathelisa. Izomisi ezijikelezayo ezineityhubhu zokuqukuqela zangaphakathi ngoku ziyilwe, ezifana nesomisi esintywiliselwayo sokuntywiliselwa ukomisa iipolima ezingeva bubushushu okanye iipellets ezinamafutha, ezisisinye kwisithathu kuphela sobukhulu besomisi esinolwelo oluqhelekileyo lwebhedi.
Ukomisa i-vacuum yinkqubo yokushisa okuphantsi kunye noxinzelelo oluphantsi lokumisa ngokufudumeza izinto phantsi kweemeko ze-vacuum ukwenza ukuba umswakama usasazeke ngaphakathi, uphuphe ngaphakathi, u-sublimate, kwaye uphephe phezu komhlaba. Ineenzuzo zobushushu obuphantsi bokufudumeza, ukusebenza kakuhle kwe-antioxidant, umxholo wokufuma wemveliso efanayo, umgangatho ophezulu kunye nokusetyenziswa. Ukomisa i-vacuum kuyabiza ukusebenza, kwaye ukomisa i-vacuum kucetyiswa kuphela xa izinto kufuneka zomiswe phantsi kobushushu obuphantsi okanye ukusilela kwe-oksijini, okanye xa kuya konakala ngokumisa phantsi kobushushu obuphakathi kunye nobushushu obuphezulu. Ngobuchule obuthile bomphunga, ukusebenza kweqondo lokushisa eliphezulu kusetyenziswa ukuze izinga lokuhamba kwegesi lincitshiswe kwaye umthamo wezixhobo ungancitshiswa. Kumsebenzi wokomisa ubushushu obuphantsi, ubushushu obuphantsi bobushushu obuphantsi okanye umqokeleli welanga unokukhethwa njengomthombo wobushushu, kodwa umthamo wesomisi mkhulu kakhulu.
Ⅲ. Ukomisa ukudibanisa
Ukusebenzisa iindlela ezahlukeneyo zokomisa, indibaniselwano yomgaqo wokomisa eyahlukeneyo, banokudlala amandla abo kwaye benze iintsilelo zabo zezixhobo zokomisa. Umzekelo, indlela yokomisa ngokuthe ngqo kunye nendlela yokumisa ngokungathanga ngqo kwaye usebenzise indlela yokumisa ngokungathanga ngqo ukubonelela ukomisa uninzi lobushushu obufunekayo. Ngale ndlela, izinga lokumisa lingaphuculwa, kwaye indlela yokomisa ngokuthe ngqo kunye neyomileyo kunye nezixhobo zokomisa kunye nomthamo wezixhobo ezincinci kunye nokusebenza okuphezulu kwe-thermal kunokufumaneka.
Izixhobo zokomisa ezidityanisiweyo zikwasetyenziswa ngakumbi nangakumbi, njengesitshizi sokutshiza kunye nendibaniselwano yesomisi sebhedi eshukumayo, isisomisi seraki kunye nendibaniselwano yesomisi esidityanisiweyo sebhedi, isomisi sokuxuba esijikelezayo, isisomisi sokuxuba, isisomisi somoya kunye nendibaniselwano yesomisi sokulala. Udibaniso lwenjongo kukufumana ukufuma okusezantsi, okufana nesitshizi sokutshiza esinye sinokufumaneka kwi-1% -3% yesiqulatho sokufuma semveliso, esifana nokufuma kwe-0.3% okanye ngaphantsi, ubushushu bombhobho buhlala bufuneka kwi-120 ℃ okanye ngaphezulu, ilahleko yamandla obushushu inkulu kakhulu. Ngokufanayo, ukuba kukho ezinye iimfuno zokufuma, isiqulatho sokufuma esingaphantsi kwe-0.1%, iqondo lobushushu lokuphuma liyafuneka ngaphezu kwe-130 ℃. Ukugcina amandla ashushu, kuyilo losetyenziso oluqhelekileyo lwe-90 ℃ yokukhupha ubushushu besomisi sokutshiza, ukuze ukufuma ukuya kwi-2%, ukubuyiswa kobushushu obuveliswa yi-60 ℃ yomoya oshushu kunokusetyenziswa kuthotho ukomisa umbhede othe tye owenziwe ngamanzi, ukuphela kokufuma kunokufikelela kwi-0.1% okanye ngaphantsi, kwaye amandla ashushu angagcina i-20%.
Kwezinye iimeko, xa imveliso isomisiwe okanye icutshungulwa, ubushushu bobushushu bemveliso buvelisa utshintsho, okanye iimpawu zotshintsho lwemveliso. Ngokucacileyo, kule meko ukusetyenziswa kweendlela ezimbini okanye ngaphezulu kweendlela ezimbini ezahlukeneyo zokudibanisa izixhobo zokumisa zilungile.
Emva koko, ungakhetha njani izomisi ezifanelekileyo kwizixhobo zakho? Wamkelekile ukunxibelelana!
