Dab tsi yog Txoj Cai Kev Ua Haujlwm ntawm Ib Lub Phaj Inclined Settling Tank?
I. Cov Ntsiab Cai Kev Ua Haujlwm (raws li Txoj Cai Tsis Txaus Siab Tank)
Los ntawm kev ntxiv cov phaj inclined rau cov tsoos tso tsheb hlau luam, nws tawg qhov kev txwv uas "lub tank qhov tob txiav txim siab sedimentation efficiency". Lub logic tseem ceeb muaj 3 ntu:
1.Shorter chaw nyob deb, ceev efficiency
Nyob rau hauv ib txwm tso tsheb hlau luam, hais hais nyob rau hauv 2-4 m; nrog cov phaj inclined, lawv tsuas yog yuav tsum tau khom 50-100mm rau lub phaj uas nyob ib sab. Thaum particle daws teeb meem nrawm, lub sij hawm daws teeb meem raug txiav mus rau 1/20-1/80 ntawm qhov qub, tuav cov dej khib nyiab ntau hauv tib lub sijhawm.
2. Qhov chaw nyob loj dua, qis dua
Cov phaj yog tilted ntawm 60 degree, yog li lawv qhov projected cheeb tsam (perpendicular rau cov dej ntws) yog ntau loj tshaj lub tank kab rov tav cheeb tsam. Nrog tib lub ntim dej khib nyiab, qhov "surface loading rate" (dej khib nyiab ib chav tsev ib teev) poob -particles tau txais sij hawm ntau los daws, tshwj xeeb tshaj yog cov zoo.
3. Auto- zawv zawg sludge, tsis muaj qhov thaiv
60℃yog steeper tshaj sludge lub repose lub kaum sab xis (30℃-45 degree). Sludge ntawm daim hlau swb mus rau hauv qab los ntawm lub ntiajteb txawj nqus, tsis muaj cov khoom siv ntxiv ntxiv, thiab tsis muaj qhov thaiv ntawm daim hlau
Ⅱ. Key Design Parameters (Simplified)

Cov Lus Qhia Tseem Ceeb |
Lub luag haujlwm tseem ceeb |
|
Daim phiaj inclined |
Qhov sib nrug ntau dua lossis sib npaug li 50mm; Ntev 1.0-1.2m; 60℃qaij; Net nrug 80-100mm |
Tiv thaiv kev thaiv; xyuas kom meej lub sijhawm; auto-sludge zawv zawg |
|
Tank Qhov siab |
0.5-1.0m dej saum daim hlau; 1.0m tsis txheej; Ntau tshaj los yog sib npaug rau 0.5m dej faib cheeb tsam |
ruaj khov dej ntws; tsis muaj sludge re- ncua kev kawm ntawv |
|
Cov dej khib nyiab |
Ntau- kab perforated kav; qhov 2cm hauv qab dej |
Uniform collection; tsis muaj teeb meem floating |
|
Flow Velocity (Cov dej phwj hauv tsev) |
0.5-0.7 hli / s |
Tsis txhob sludge tsub zuj zuj los yog scouring |
Ⅲ. Simple Design Calculation (Piv txwv: Cov Dej Dej Hauv Tsev)
Muab:Cov dej khib nyiab (Q=500m^3/h); particle daws ceev (U0= 0.3mm/s)
Cov cim tseem ceeb:Daim hlau (100mm qhov sib txawv, 1.2m ntev, 60℃qaij); khiav ceev 0.6mm / s; tank qhov siab (0.8m saum daim hlau, 1.0m tsis, 0.5m faib, 1.5m sludge)
Cov txiaj ntsig tseem ceeb:
Tag nrho cov phaj projected cheeb tsam: ~ 535m²; Tus naj npawb ntawm daim phiaj: ~ 450 (1m dav txhua)
Tank dav: ~ 45m (los yog 8 daim phiaj × 5.6m txhua); Tag nrho qhov tob: ~ 4.9m
Ⅳ. Tau ua tiav cov kev daws teeb meem & cov qauv dawb
Cov saum toj no yog lub hauv paus ntsiab lus. Cov phiaj xwm tiag tiag xav tau kev hloov kho rau cov dej khib nyiab zoo, qhov chaw nyob, thiab cov qauv.
