Ultrasonic homogenizer qhov cuab yeej ntsuab los daws cov teeb meem ntawm kev kho dej phwj

Nyob rau hauv lub qhov kev siv hluav taws xob ntawm thoob ntiaj teb thiab kev kho dej kom zoo dua qub rau kev nyab xeeb rau kev nyab xeeb rau kev nyab xeeb thiab kev noj qab haus huv tib neeg. Qhov no muaj tseeb tshwj xeeb rau kev lag luam wensewater (xws li los ntawm kev luam tawm thiab tawg, thiab cov tshuaj tua kab mob orgocarians zoo li orgocaricts li orgofle, thiab kev kho mob thornocarics) Cov txheej txheem kev kho mob ib txwm muaj feem ntau ntsib cov kev sib tw xws li qis qis, kev ua qias tuaj thib ob, thiab cov nqi siab. Ultrasonic homogenizers, nrog lawv tshwj xeeb "cavitation nyhuv, thiab ib puag ncig cov phooj ywg kev kho mob, thiab tau dhau los ua ib qho kev sib raug zoo hauv kev lag luam.

 

1. Tus "tseem ceeb riam phom" ntawm ultrasonic homogenizer: Cavitation Yauj Assab

Txhawm rau kom nkag siab tias yog vim li cas ultrasonic homogenizers tuaj yeem kho cov neeg khib nyiab, peb xub xav kom nkag siab txog lawv cov tub ntxhais ua haujlwm ua haujlwm {}} Cov nyhoo cov nyhitation. Thaum Ultrasonic vuam (feem ntau nrog ib zaus ntawm 20kHz- 1mHz) dhau mus rau cov kua roj me me "(tsuas yog ob peb rau kaum ntawm microns ntawm lub cheeb). Cov npuas no tau nthuav ntau thaum lub suab tsis zoo ntawm lub suab nthwv dej thiab tam sim ntawd ua tiav thaum lub sijhawm siab siab. Tag nrho cov txheej txheem no tsuas yog microseconds, tab sis nws tsim heev heev hauv zos ib puag ncig:

Kev kub siab thiab kub siab: Lub caij ntawm npuas sib tsoo, lub zos kub tuaj yeem ncav cuag 5000k (txog 4727 degree) thiab lub siab tuaj yeem ncav cuag 100-500mpa, uas yog piv rau "qhov tawg micro";

Muaj zog poob siab tsis thiab microjets:Lub suab nrov thiab siab {- ceev tus microthets (txaus mus txog 100m / s) muaj kuab lom lossis sludge flocs;

Muaj zog oxidizing dawb radicals:Nyob rau hauv cov xwm txheej huab, dej molecules yuav decompose los ua cov tshuaj oxidizing muaj zog xws li hydroxyl radicals (· hecoborts (· h). Ntawm lawv, · Oh muaj qhov muaj peev xwm ua tau lub peev xwm siab npaum li 2.8v thiab tsis tuaj yeem- Xaiv tau cov neeg muaj kuab paug organic ntau tshaj plaws.

Nws yog qhov kev cuam tshuam no ntawm "kev cuam tshuam ntawm lub cev + uas ua rau cov tshuaj ntsuab ultrasonic, tab sis kuj ua tiav cov hom kuab paug thiab tsis muaj kev lim hiam thiab txo qis.

2. Kev Tshawb Fawb Kev Ua Si: Cov Ntawv Thov Qauv Ntawm Ultrasonic Homogenizer nyob rau hauv Kev Kho Kom Qhuav

Lub ultrasonic homogenizer tsis yog ib qho kev kho mob, tab sis tuaj yeem kho cov txheej txheem thiab cov hom dej tsis haum, yog li daws cov ntsiab lus mob ntawm cov thev naus laus zis tsoos.

(I) Kev Kho Mob Refractory Almic Wastewater: tawg "tawv ncauj" cov kuab paug

Refractory cov teeb meem hauv kev lag luam Wastewater (xws li azo dyes hauv luam ntawv quav dej, thiab cov tshuaj tiv thaiv roj av hauv cov roj av, muaj cov qauv siv hluav taws xob zoo nkauj thiab cov txiaj ntsig zoo. Kev kho mob roj ntsha yog qhov nyuaj rau kev ua kom degrade, thaum cov khoom siv oxidation yuav tsum tau ntau ntawm cov reagents (xws li Fenton's Reidly Slude kev sib kis. Ultrasonic homogenizers muaj peev xwm rhuav tshem cov qauv molecular ntawm cov kuab paug los ntawm cov kuab paug los ntawm cov kuab paug:

Decolorization thiab Cod tshem tawm hauv Dyeing Wastewater:Cov Chromophores ({- n= n}} n}} n}}} nov radicals thiab huag radicals, ua tiav kev txiav tawm ua tau zoo. Kev sim cov ntaub ntawv qhia tau tias siv ultrasonic homogenizer nrog ib zaus ntawm 20kl / l

Kev tsis pom zoo ntawm cov tshuaj tua kab mob hauv cov tshuaj pov tseg:Rau cov tshuaj tua kab mob xws li penicillin thiab tetralcline, cov huag radicals tsim los ntawm yooj yim molecules (xws li carboxylic acids, CO₂, thiab H₂O). Tom qab lub tuam txhab kws tshuaj siv cov tshuaj tiv thaiv ultrasonic, cov tshuaj tiv thaiv kev tiv thaiv roj ntsha tau nce los ntawm cov kab mob roj ntsha ua kom tiav los ntawm kev ua haujlwm ntawm kab mob ntsig txog "lom" cov roj ntsha dej.

Petrochemical Cov Roj Tshem Tawm Tso Dej:Ultrasonic microjets tuaj yeem tsoo cov roj av khov ntawm cov roj hauv dej, ua rau cov roj ntws mus rau Coalesce thiab loj dua. Ua ke nrog cov flotation los yog kev tshem tawm cov roj tshem tawm tuaj yeem nce los ntawm 60% nrog cov txheej txheem tsoos rau ntau dua 90%, tsis tas yuav demulsifiers.

(II) sludge kev kho: daws cov kev nyuaj ntawm sludge txo thiab dewatering

Cov dej phwj dej hauv nroog Kev cog qoob loo cov zaub mov muaj cov ntsiab lus tsis txaus (feem ntau tsuas yog 1% {%) thiab yog qhov nyuaj rau cov khoom seem. Txawm hais tias tom qab ib txwm muaj cuab kav dej tshuab dewatering (xws li thav duab lim ntawv), tshaj 80%, ua rau muaj cov nqi siab rau cov av pov tseg ntxiv lossis kev sib cais. Ultrasonic homogenizers tuaj yeem txhim kho sludge dewatering kev ua tau zoo los ntawm "kev kho mob fragmentation":

Cuam tshuam sludge floc qauv:Cov microbial flocs hauv sludge yog muaj ntawm cov phab ntsa ntawm tes thiab cov tshuaj txhuam polymellic (eps). Lub cavitation chead tsis muaj ultrasound tuaj yeem tshem cov flocs, tso cov dej dawb thiab ua txhaum hauv.

Txo sludge tshwj xeeb tiv:Qhov siab dua qhov sludge tshwj xeeb (ib qho kev ntsuas ntawm kev teeb meem dewatering), qhov nyuaj dua nws yog los ntsaws. Tom qab ultrasonic pretrealment (25kHz zaus, 500W lub zog, 15 feeb), cov kab ke tsis txaus siab tuaj yeem txo qis rau hauv qab 65%, thiab cov sludge ntim tuaj yeem txo tau ntawm ze li 40%.

Ua kom nrawm AAIEROBIC kev zom:Cov shredded sludge tso ib qho nyiaj ntau ntawm cov organic (xws li cov protein ntau thiab polysaccharides), muab cov txheej txheem txaus siab rau anaerobic microorganisms. Qhov no nce methane ntau lawm los ntawm 20% -30% thiab luv lub plab zom mov los ntawm 15%, ua tiav rau cov txiaj ntsig dual Lub tsheb khiav tawm hauv nroog kev cog qoob loo siv cov thev naus laus zis txhua xyoo, txo txhua xyoo cov nqi pov tseg txhua xyoo muaj kwv yees li 2.8 lab yuan.
