1, Qhia qhov laj thawj rau kev nyuaj
Qhov teeb meem tseem ceeb hauv kev tsim cov iav ultra dawb ntab yog qhov qhia meej ntawm cov kua iav. Ultra-dawb iav muaj cov ntsiab lus hlau tsawg thiab cov thermal conductivity, uas yog 3-4 npaug ntawm cov iav zoo tib yam. Qhov no ua rau muaj kev sib tw zoo rau lub melting ntawm ultra dawb ntab iav, ua rau nws nyuaj rau cov iav kua kom ntshiab thiab rau cov npuas kom yooj yim tshem tawm. ① Vim muaj cov ntsiab lus hlau tsawg, ultra dawb ntab iav muaj cov thermal conductivity zoo, iav kua kub kub, tsis muaj viscosity, muaj zog kab rov tav convection siv, thiab lub sij hawm nyob rau hauv lub sij hawm luv luv nyob rau hauv lub clarification cheeb tsam raws li ib tug ncig. ② Vim tias cov ntsiab lus hlau tsis tshua muaj, qhov ntsuas kub ntsug hauv qhov tob tob ntawm lub pas dej ua ke yog qhov me dua li cov iav ntab zoo tib yam, thiab qhov kub hauv qab ntawm lub pas dej yog li 6% siab dua li cov iav ntab ntab. Qhov kub sib txawv ntawm qhov nruab nrab thiab qis ntawm cov kua iav yog qhov me me, txo qis convection thiab ua rau nws nyuaj rau tshem tawm npuas ntau dua li cov iav ntab zoo tib yam Qhov kub ntawm cov iav reflux kua hauv qab lub voj voog txuas ntxiv nce thaum lub sij hawm rau pem hauv ntej, ua rau cov microbubbles uas twb tau nqus los ntawm cov kua iav kom rov tso rau hauv cov kua iav hauv qab qhov kev txiav txim ntawm thermochemistry. Nyob rau tib lub sijhawm, cov viscosity ntawm cov iav iav uas tsis muaj hlau yog tsawg, thiab cov microbubbles tau yooj yim nqa mus rau hauv qhov chaw ntws, ua rau muaj qhov nce ntxiv hauv cov npuas dej hauv cov kua iav hauv txhua qhov cua sov ntawm cov pa roj carbon monoxide combustion, cov dej vapor. Cov ntsiab lus yog qhov siab, suav txog 1/3 txog 2/3 ntawm cov roj muaj pes tsawg leeg hauv qhov chaw nplaim taws, thiab cov ntsiab lus siab ntawm qhov chaw kub ntawm lub iav kua nto, ncav cuag 1/2. Raws li cov ntsiab lus noo noo nce, cov kua iav ua rau nyuaj kom meej meej thiab muaj microbubbles ntau dua.
2, Txoj kev daws teeb meem
(1) Kho cua sov load
Txo cov cua sov load ntawm lub melting Circuit Court. Noj 6 khub ntawm qhov cub me me ua piv txwv, txo cov cua sov ntawm cov cub tawg me me 1 # mus rau 3 #, nce cov cua sov ntawm cov cub tawg me me 4 # mus rau 5 #, thiab me ntsis nce cov cua sov ntawm lub cub tawg me me 6 #. Qhov no tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm ultra dawb ntab iav. Lub ultra dawb ntab iav kua muaj cua sov zoo permeability, ua rau cov khoom siv batch ntau yooj yim yaj, yog li txo cov cua sov ntawm lub melting Circuit Court. Thiab nws qhov nyuaj ntawm kev qhia meej, tshwj xeeb tshaj yog cov yam ntxwv uas microbubbles tsis yooj yim absorbed, tsub kom lub tshav kub load ntawm clarification Circuit Court raws li. Txawm li cas los xij, qhov nce tsis tuaj yeem siab dhau rau qhov cub me me, txwv tsis pub cov microbubbles absorbed los ntawm iav hauv reflux iav kua hauv qab cov dej ntws yuav yooj yim nce mus rau saum npoo thiab tsim cov npuas thib ob.
(2) Kev siv cov kev pab cuam
Hauv qab bubbling thev naus laus zis tuaj yeem siv tau, cov khoom sib xyaw ua kom pom tseeb tuaj yeem muab ntxiv rau hauv qhov sib xyaw, cov defoamers tuaj yeem ntxiv, thiab lwm yam kev paub meej tshaj plaws ntawm cov thev naus laus zis yuav tsum tau ua ke kom txo tau cov npuas hauv cov kua iav.
