Crystallizer

1. Tanthauzo: akristalondi chidebe chooneka ngati mbiya chokhala ndi jekete pakhoma kapena chubu cha njoka mu nkhungu kuti chitenthe kapena kuziziritsa madzi mu thanki.Tanki ya crystallization ingagwiritsidwe ntchito ngati evaporation crystallizer kapena kuzirala kwa crystallizer.Pofuna kupititsa patsogolo kukula kwa kristalo, chotsitsimutsa chikhoza kuwonjezeredwa mu thanki.Tanki ya crystallization imatha kugwiritsidwa ntchito mosalekeza kapena ntchito yapakatikati.The kristalo wopezedwa ndi ntchito yapakatikati ndi yaikulu, koma krustalo n'zosavuta kulumikizidwa mu masango kristalo ndi entrain mowa mowa, zomwe zimakhudza chiyero cha mankhwala.Ma crystallizer ali ndi mawonekedwe osavuta komanso otsika kwambiri, ndipo ndi oyenera kupanga zinthu zazing'ono (monga ma reagents amankhwala ndi biochemical reagents).
2. Kuyenda mokakamizidwa
Chitsanzo chothandizira chikugwirizana ndi crystallizer yosalekeza yokhala ndi crystal slurry circulation.Panthawi yogwira ntchito, madzi odyetsa amawonjezedwa kuchokera kumunsi kwa chitoliro chozungulira, chosakanikirana ndi crystal slurry kuchoka pansi pa chipinda cha crystallization, ndiyeno amapopera ku chipinda chotenthetsera.Dothi la kristalo limatenthedwa m'chipinda chotenthetsera (nthawi zambiri 2 ~ 6 ℃), koma sichimatuluka.Pambuyo pa crystal slurry yotentha ikalowa m'chipinda cha crystallization, imawira kuti yankho lifike pamtunda wapamwamba kwambiri, kotero kuti gawo la solute limayikidwa pamwamba pa njere zoyimitsidwa kuti kristaloyo ikule.The crystal slurry monga mankhwala amatulutsidwa kuchokera kumtunda kwa chitoliro chozungulira.Anakakamizika kufalitsidwa evaporation crystallizer ali lalikulu kupanga mphamvu, koma tinthu kukula kugawa mankhwala ndi lonse.
3. Mtundu wa DTB
Ndiko kuti, kristalo wa chubu chopukutira evaporation ndi crystal slurry circulating crystallizer (onani chithunzi chamtundu).Chigawo cha elutriation chimalumikizidwa kumunsi kwa chipangizocho, ndipo silinda yowongolera ndi cylindrical baffle imayikidwa mu chipangizocho.Panthawi yogwira ntchito, madzi otentha otentha amawonjezedwa mosalekeza kumunsi kwa chitoliro chozungulira, chosakanikirana ndi madzi amadzimadzi ndi makhiristo ang'onoang'ono mu chitoliro chozungulira, ndiyeno amapopedwa ku chowotcha.Njira yotenthetsera imalowa mu crystallizer pafupi ndi pansi pa chubu cholembera ndipo imatumizidwa ku mlingo wamadzimadzi pamodzi ndi chubu chojambula ndi propeller yozungulira pang'onopang'ono.The njira ndi chamunthuyo ndi utakhazikika pa madzi pamwamba kufika supersaturated boma, imene solutes waikamo pamwamba pa inaimitsidwa particles kuti galasi kukula.Palinso malo okhala pafupi ndi annular baffle.M'dera lokhazikika, tinthu tating'onoting'ono timakhazikika, pamene tinthu tating'onoting'ono timalowa mu chitoliro chozungulira ndi madzi amadzimadzi ndikusungunuka kutentha.The krustalo amalowa ndime elutriation pansi pa crystallizer.Kuti tinthu kukula crystalline mankhwala monga yunifolomu, mbali ya mowa mayi ku dera kukhazikika anawonjezera pansi pa ndime elutriation, ndi particles ang'onoang'ono kubwerera crystallizer ndi otaya madzi pogwiritsa ntchito ntchito. za hydraulic classification, ndipo zinthu za crystalline zimatulutsidwa kuchokera kumunsi kwa gawo la elutriation.
4. Mtundu wa Oslo
Imadziwikanso kuti Kristal crystallizer, ndi mowa wamayi womwe umazungulira mosalekeza (mkuyu 3).Madzi opangira ntchito amawonjezedwa ku chitoliro chozungulira, chosakanikirana ndi madzi ozungulira a mayi mupaipi, ndikuponyera kuchipinda chotenthetsera.Njira yotenthetsera imasanduka nthunzi mu chipinda cha evaporation ndikufikira ku supersaturation, ndikulowa mu bedi la crystal fluidized pansi pa chipinda cha evaporation kudzera mu chubu chapakati (onani fluidization).Mu kristalo fluidized bedi, ndi supersaturated solute mu njira waikamo pamwamba pa inaimitsidwa particles kuti krustalo kukula.Bedi la crystal fluidized hydraulically limapanga tinthu tating'onoting'ono.Tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono.The crystalline mankhwala ndi yunifolomu tinthu kukula amatulutsidwa pansi pa bedi fluidized.Tinthu tating'onoting'ono ta bedi lamadzimadzi timayenda mu chitoliro chozungulira ndi madzi amadzi ndikusungunula tinthu tating'ono tating'ono tikamawotcha.Ngati chipinda chotenthetsera cha Oslo evaporative crystallizer chasinthidwa ndi chipinda chozizira ndipo chipinda cha evaporation chichotsedwa, chowuzira chozizira cha Oslo chimapangidwa.Choyipa chachikulu cha zida izi ndikuti solute ndiyosavuta kuyiyika pamalo otengera kutentha ndipo ntchitoyo ndi yovuta, chifukwa chake siigwiritsidwa ntchito kwambiri.
5. Kuneneratu za kutha
(1) Yang'anirani kukangana kuti munenere kuphulika.Njira zomwe zimagwiritsidwa ntchito kwambiri ndikuyika dynamometer pa silinda ya hydraulic hydraulic, tester pa chipangizo chogwedezeka, ndi accelerometer ndi Dynamometer pa nkhungu kuti azindikire kukangana.Chifukwa momwe kagwiridwe kake kachipangizo kakugwedezeka kumakhudza kwambiri kuyeza kwa mikangano, kuyeza kulondola kwa mikangano kumakhala kovuta kutsimikizira.Ngakhale kuti njirayi ndi yophweka, kulondola kwake sikuli kokwera kwambiri, ndipo kungangodziwiratu kuphulika kwa mgwirizano, zomwe nthawi zambiri zimabweretsa alamu yabodza pakupanga.
(2) Ulosi wosweka umachitika molingana ndi kusintha kwa kutentha mu nkhungu.Njira yosavuta komanso yolunjika ndiyo kuyeza kusiyana kwa kutentha pakati pa kutentha kwa madzi olowera ndi kutentha kwa madzi otuluka mumadzi ozizira a nkhungu, koma njirayi nthawi zambiri imasocheretsa.Amagwiritsidwa ntchito kuyeza kutentha kwa kutentha kuti adziwiretu kuphulika.Ngati kutengerapo kutentha pagawo la nkhungu kumagwiritsidwa ntchito pakulosera kwapang'onopang'ono, wogwiritsa ntchitoyo amatha kuchitapo kanthu moyenera malinga ndi kutengera kutentha pagawo lililonse, monga kuchepetsa liwiro lojambula, kukulitsa liwiro lojambula, kusiya kuthira, ndi zina zambiri.
(3) Muyezo wa mbale ya mkuwa wa thermocouple ndi kulosera kwapang'onopang'ono.Kulondola kwa kulosera kwapang'onopang'ono kwa kuyeza kwa thermocouple mbale yamkuwa ndikokwera kwambiri.Dongosolo lolosera zam'tsogolo laukadaulo wapamwamba kwambiri limatengera kulosera kwa thermocouple breakout.Mfundo yake yogwirira ntchito ndikuyika ma thermocouples angapo pa nkhungu.Mtengo wa kutentha wa thermocouples umatumizidwa ku makompyuta.Ngati ipitilira mtengo womwe watchulidwayo, ipereka alamu, ndipo imangotengera njira zofananira kapena oyendetsa amatenga ntchito zofananira kuti apewe kuphulika.Njirayi ili ndi ntchito zolosera kusweka kwa ma bond, kusweka, kusweka kwa slag, kukhumudwa kwa slab ndikuwonetsa kulimba kwa chipolopolo cha slab mu nkhungu.Zambiri zake zimaphatikizidwa mu dongosolo lolosera zamtundu wa slab.
