ICrystallizer

1. Ingcaciso: aicrystallizersisikhongozeli esimilise okwesikhongozelo esinebhatyi eludongeni okanye ityhubhu yenyoka ekumngundo ukutshisa okanye ukupholisa isisombululo kwitanki.Itanki yecrystallization ingasetyenziswa njenge crystallizer yomoya okanye icrystallizer yokupholisa.Ukuze kuphuculwe ubukhulu bemveliso yekristale, i-stirrer inokongezwa kwitanki.I-tank ye-crystallization ingasetyenziselwa ukusebenza ngokuqhubekayo okanye ukusebenza ngokuphindaphindiweyo.I-crystal efunyenwe ngokusebenza kwesikhashana inkulu, kodwa i-crystal ilula ukudibaniswa kwi-crystal clusters kunye ne-entrain mother alcohol, echaphazela ukucoceka kwemveliso.I-crystallizer inesakhiwo esilula kunye nobukhulu obuphantsi bemveliso, kwaye ifanelekile ukuveliswa kweemveliso ezincinci zebhetshi (ezifana neekhemikhali ze-reagents kunye ne-biochemical reagents).
2. Ukusasazwa ngenkani
Imodeli eluncedo inxulumene nekristali eqhubekayo kunye nokujikeleza kwekristale oludaka.Ngethuba lokusebenza, i-liquid feed yongezwa ukusuka kwindawo engezantsi yombhobho ojikelezayo, ixutywe ne-crystal slurry eshiya ngaphantsi kwegumbi le-crystallization, kwaye emva koko iphonswe kwigumbi lokufudumeza.Udaka lwekristale lufudunyezwa kwigumbi lokufudumeza (ngokuqhelekileyo i-2 ~ 6 ℃), kodwa aluphumi.Emva kokuba i-crystal slurry eshushu ingene kwigumbi le-crystallization, iyabilisa ukwenza isisombululo sifikelele kwi-supersaturated state, ngoko ke inxalenye ye-solute ifakwe kumphezulu weenkozo ezimisiweyo ukuze i-crystal ikhule.I-crystal slurry njengemveliso ikhutshwe kwindawo ephezulu yombhobho ojikelezayo.Icrystallizer yokujikeleza okunyanzeliswayo inamandla amakhulu okuvelisa, kodwa ukuhanjiswa kobungakanani bemveliso kubanzi.
3. Uhlobo lwe-DTB
Oko kukuthi, i-crystal baffle baffle evaporation ityhubhu ikwayikristale eludaka olujikeleza icrystallizer (jonga umfanekiso wombala).Ikholamu ye-elutriation iqhagamshelwe kwindawo engezantsi yesixhobo, kwaye i-cylinder yesikhokelo kunye ne-cylindrical baffle iseti kwisixhobo.Ngexesha lokusebenza, ulwelo olushushu olushushu luyongezwa ngokuqhubekayo kwindawo engezantsi yombhobho ojikelezayo, exutywe nolwelo lomama kunye neekristale ezincinci kumbhobho ojikelezayo, emva koko uphonswe kwi-heater.Isisombululo esishushu sigeleza kwi-crystallizer kufuphi nomzantsi wetyhubhu yedrafti kwaye ithunyelwe kwinqanaba le-liquid kunye ne-drafti yetyhubhu nge-propeller ejikeleza ngokukhawuleza.Isisombululo siphendukile kwaye sipholile kwindawo yolwelo ukufikelela kwimo ephezulu, apho ezinye i-solutes zifakwe kumphezulu wamasuntswana amisiweyo ukwenza ikristale ikhule.Kukho kwakhona indawo yokuhlala ejikeleze i-annular baffle.Kwindawo yokumisa, iinqununu ezinkulu zihlalisa, ngelixa iincinci ezincinci zingena kumbhobho ojikelezayo kunye nolwelo ngumama kwaye zichithe phantsi kobushushu.I-crystal ingena kwikholamu ye-elutriation ezantsi kwe-crystallizer.Ukuze wenze ubungakanani bamasuntswana eemveliso zekristale njengeyunifomu kangangoko kunokwenzeka, inxalenye yotywala unina ukusuka kwindawo yokuhlala yongezwa ezantsi kwikholamu elutriation, kwaye amasuntswana amancinane abuyele crystallizer kunye flow ulwelo ngokusebenzisa umsebenzi. yokuhlelwa kwe-hydraulic, kunye neemveliso ze-crystalline zikhutshwa kwindawo engezantsi yekholomu ye-elutriation.
4. Uhlobo lwe-Oslo
Ikwabizwa ngokuba yiKristal crystallizer, butywala bemama obujikeleza icrystallizer eqhubekayo (Umfanekiso 3).Ulwelo lokutya olusebenzayo longezwa kumbhobho ojikelezayo, luxutywe nolwelo lomama ojikelezayo kumbhobho, kwaye luphonswe kwigumbi lokufudumeza.Isisombululo esifudumeleyo siyaphuphuma kwigumbi lokufuduka kwaye sifikelele kwi-supersaturation, kwaye singene kwibhedi ye-crystal fluidized engaphantsi kwegumbi lokunyuka komphunga ngokusebenzisa ityhubhu ephakathi (jonga i-fluidization).Kwibhedi ye-crystal fluidized, i-supersaturated solute kwisisombululo ifakwe kumphezulu weengqungquthela ezimisiweyo ukuze i-crystal ikhule.Ibhedi ye-crystal fluidized hydraulically ihlela amaqhekeza.Amasuntswana amakhulu asezantsi kwaye amancinci amancinci angaphezulu.Iimveliso ze-crystalline ezinobungakanani obufanayo zikhutshwe phantsi kwebhedi edibeneyo.Iincinci ezincinci kumandlalo omanzi zihamba kumbhobho ojikelezayo kunye nolwelo lukamama kwaye zinyibilikise iikristale ezincinci xa zifudumeza.Ukuba igumbi lokufudumeza le-Oslo evaporative crystallizer lithatyathelwa indawo ligumbi lokupholisa kunye negumbi lokufudumeza lisusiwe, i-Oslo yokupholisa icrystallizer yenziwa.Ukungalungi okuphambili kwesi sixhobo kukuba i-solute ilula ukuyifaka kwindawo yokudlulisa ubushushu kwaye umsebenzi unzima, ngoko awusetyenziswanga ngokubanzi.
5. Ukuxela kwangaphambili
(1) Lawula ingxabano ukuze uqikelele ukuqhambuka.Iindlela ezisetyenziswa ngokuqhelekileyo kukufaka i-dynamometer kwi-vibration hydraulic cylinder, umvavanyi kwisixhobo sokungcangcazela, kunye ne-accelerometer kunye ne-Dynamometer kwi-mold ukubona ukukhuhlana.Ngenxa yokuba imeko yokusebenza kwesixhobo sokungcangcazela inempembelelo enkulu kumlinganiselo wokukhuhlana, ukuchaneka komlinganiselo wokukhuhlana kunzima ukuqinisekisa.Nangona le ndlela ilula, ukuchaneka kwayo akuphezulu kakhulu, kwaye inokuqikelela kuphela ukuqhambuka kokubambisana, okuhlala kukhokelela kwi-alamu yobuxoki kwimveliso.
(2) Ukuqikelelwa kokuqhekeka kwenziwa ngokuhambelana nokutshintshwa kobushushu kwi-mold.Eyona ndlela ilula kunye nethe ngqo kukulinganisa iqondo lobushushu phakathi kobushushu bamanzi angenayo kunye nobushushu bamanzi obuphuma kumanzi okupholisa ngundo, kodwa le ndlela ihlala ilahlekisa.Isetyenziselwa ukulinganisa ukuhanjiswa kobushushu ukuqikelela ukuqhambuka.Ukuba ukuhanjiswa kobushushu kwiyunithi yendawo yokubumba kusetyenziselwa ukubikezela ukuphuka, umqhubi unokuthatha izenzo ezichanekileyo ngokuhambelana nokutshintshwa kobushushu kwindawo nganye yeyunithi, njengokunciphisa isantya sokudweba, ukwandisa isantya sokudweba, ukuyeka ukuthulula, njl.
(3) Umlinganiselo we-thermocouple yepleyiti yobhedu kunye noqikelelo lokuqhawuka.Ukuchaneka kokuqikelelwa kokuqhawuka komlinganiselo we-thermocouple yepleyiti yethusi iphezulu kakhulu.Inkqubo yokuxela kwangaphambili i-high-tech isekelwe ikakhulu kwi-thermocouple breakout prediction.Umgaqo wayo wokusebenza kukufaka ii-thermocouples ezininzi kwi-mold.Ixabiso leqondo lokushisa le-thermocouples lidluliselwa kwinkqubo yekhompyutheni.Ukuba idlula ixabiso elichaziweyo, liya kunika i-alamu, kwaye ngokuzenzekelayo ithathe amanyathelo ahambelanayo okanye abaqhubi bathathe imisebenzi ehambelanayo ukuphepha ukuphuka.Le ndlela inemisebenzi yokuqikelela ukugqabhuka kwebhondi, ukuqhawuka kwe-crack, i-slag inclusion breakout, ukudakumba kwe-slab kunye nokubonisa ngokubonakalayo ukuqina kwegobolondo ye-slab kwi-mold.Ulwazi lwayo lufakwe kwinkqubo yokuqikelela umgangatho we-slab.
