Ib lub tank zoo tib yam tshem tawm 40-70% ntawm cov khib nyiab tshem tawm thiab tuav cov hneev taw ntsuas hauv ntau pua square metres. Ib tug inclined tube settler nrog tib hneev taw tshem tawm tshaj 90% - thiab tuav ob zaug ntws. Qhov sib txawv tsis yog cov tshuaj zoo dua los yog kev tswj xyuas zoo dua. Nws yog geometry. Los ntawm kev txhim kho inclined parallel tubes nyob rau hauv thaj chaw nyob, lub tank multiplies nws zoo sedimentation cheeb tsam los ntawm ib yam ntawm kaum los yog ntau tshaj, thaum tib lub sij hawm stabilizing cov ntws mus rau hauv ib tug laminar tsoom fwv uas cia hais hais tias nyob twj ywm es tsis txhob nyob twj ywm. Cov kab lus no yog ib qho kev siv tag nrho: yuav ua li cas inclined tube settlers ua hauj lwm, lawv tsim li cas, dab tsi tsim tsis tswj lawv cov kev ua tau zoo, thiab qhov twg lawv siv.
I. KEV UA HAUJ LWM - VIM LI CAS HAIV NEEG PHEM sai dua
Lub inclined tube settler yog tsim los ntawm ib qho ntawm cov qauv qub tshaj plaws thiab zoo nkauj tshaj plaws nyob rau hauv sedimentation engineering:qhov ntiav lub tank, lub sijhawm luv dua. Qhov zoo tshaj plaws sedimentation formula hais tias:
u₀=Q / A thiab t=H / u₀
Qhov twg u₀ yog tus nqi ntws dhau (surface loading), Q yog tus nqi ntws, A yog thaj tsam sedimentation, t yog lub sijhawm nyob, thiab H yog qhov tob dej. Los ntawm ob txoj kev sib raug zoo no, ob qho kev tsim qauv tsim tawm:
Lever 1 - Nce cheeb tsam, txo tus nqi ntws.Rau qhov muab ntws Q, ua qhov loj dua txo u₀. Qhov qis dua tus nqi txhais tau hais tias ib qho me me uas muaj qhov nrawm nrawm dua tuaj yeem ncav cuag thaj tsam sludge ua ntej cov dej tawm hauv lub tank. Ntau thaj tsam=tshem tawm zoo dua.
Lever 2 - Txo qhov tob, txo lub sijhawm.Rau qhov muab u₀, ua H me me txo t proportionally. Yog tias koj faib lub tank ntawm qhov tob H rau hauv n kab rov tav txheej ntawm qhov tob H / n, txhua txheej tuaj yeem kho tib lub ntim dej nrog tib qhov kev tshem tawm - tab sis hauv 1 / n ntawm lub sijhawm, thiab yog li ntawd hauv 1 / n ntawm lub tank ntim.
Qhov no yog qhov ntiav-txoj cai tob. Ib qho yooj yim sedimentation tank yog ib txheej tob. Ib qho inclined tube settler hloov qhov sib sib zog nqus txheej nrogkaum ob qhov sib npaug sib luag, txhua tus coj raws li qhov chaw nyob ywj pheej. Qhov zoo sedimentation cheeb tsam multiplies yam tsis ua kom lub tank hneev taw.
Cov raj inclined ua ntau tshaj li subdivide lub tank. Vim hais tias txhua lub raj muaj qhov loj wetted perimeter txheeb ze rau nws tus ntoo khaub lig-sectional cheeb tsam,hydraulic radius poob sharply. Nyob rau tib lub kab rov tav ntws nrawm V, Reynolds tus naj npawb Re yog tsav deb hauv qab lub laminar - ntws qhov pib ntawm 500 - feem ntau nyob ib ncig ntawm 50 lossis qis dua - thaum Froude tus naj npawb Fr nce. Cov dej ntws hauv cov raj yuav ruaj khov thiab laminar. Turbulence, uas khaws cov khoom hauv kev ncua, yog suppressed. Cov khoom nyob rau hauv qis dua ntawm txhua lub raj, sib sau ua ib txheej sludge nyias, thiab xaub los ntawm lub ntiajteb txawj nqus ntawm 60℃inclination rau hauv cov sludge hopper. Cov dej ntshiab tau nce thiab tawm los ntawm cov khoom ntim khoom.
II. STRUCTURE - Peb txoj kev teeb tsa, ib qho kev xaiv tseem ceeb
Ib qho inclined tube settler tau muab faib ua cov chaw ua haujlwm: lubinlet faib zone, covthaj chaw faib dejhauv qab lub raj, lubtub nyob tsam, covthaj tsam dej ntshiabsaum lub cev, atsam tsis muaj, thiab covsludge cheeb tsamhauv qab. Cov hlab lawv tus kheej tau teeb tsa ntawm lub kaum sab xis - feem ntau60 degree- uas muab txoj kab nqes txaus rau cov sludge kom xaub los ntawm lub ntiajteb txawj nqus thaum ua kom pom qhov chaw nyob qhov twg.
Raws li kev txheeb ze ntawm cov dej ntws thiab sludge txav, inclined tube settlers poob rau hauv peb qhov kev teeb tsa:
| Kev teeb tsa | Flow vs. Sludge Direction | Nws ua haujlwm li cas | Siv dav |
| Counter-tam sim no (hetero-tam sim no) | Cov dej ntws nce siab; sludge swb downward - opposite directions | Cov dej nkag mus rau hauv qab cov hlab, nce los ntawm. Particles nyob rau hauv qis tube nto, swb mus rau hauv sludge cheeb tsam. | Feem ntau siv dav. Kev kho dej, dav dav sedimentation. |
| Co-tam sim no | Dej thiab sludge ntws nyob rau hauv tib txoj kev | Cov dej nkag los ntawm sab saum toj, ntws downwards nrog daws sludge. Tsis tshua muaj vim hydraulic complexity. | Roj-kev sib cais dej, kev siv tshwj xeeb hauv kev lag luam. |
| Hla -tam sim no | Dej ntws horizontally; sludge swb down ntawm ib lub kaum sab xis | Dej taug kev hla lub raj axis thaum cov khoom nyob rau ntawm lub raj qis. | Niche daim ntawv thov; ua haujlwm tsawg dua li qhov ntsuas - tam sim no rau feem ntau cov dej num. |
Counter-tam sim no yog qhov tseem ceeb configurationhauv kev kho dej thiab dej khib nyiab. Cov lus qhia tsis sib haum xeeb - dej nce, sludge poob - tsim ib qho kev sib cais uas ua rau kom muaj kev sib cuag ntawm cov khoom thiab qhov chaw nyob thaum ua kom pom tseeb cov dej ntws tawm ntawm txoj kev luv luv thiab ncaj qha.
III. TXOJ CAI PARAMETERS - QHOV CHAW UA HAUJ LWM
Cov kev txwv hauv qab no tsim cov qauv tsim tshwj xeeb rau txhua qhov inclined tube settler. Cov txiaj ntsig sab nraud cov kab no feem ntau qhia tias dhau -tsim (khoom hneev taw thiab peev) lossis qis dua -tsim (kev pheej hmoo ntawm turbid effluent thiab tube clogging).
| Parameter | Pom zoo Range | Sau ntawv |
| Nto load (overflow rate) | ~ 2 × zoo tib yam sedimentation tank | Lub ntsiab kom zoo dua. Ib tug inclined tube settler lis roughly ob zaug ntawm hydraulic load ntawm ib tug pa tank nrog tib hneev taw. |
| Tube diam (lub voj voog inscribed) | 50-80 hli | Cov kab me me=laminar ntws zoo dua thiab ua haujlwm siab dua, tab sis muaj kev pheej hmoo siab clogging ntau dua . 50 mm yog tus qauv rau kev kho dej; 80 mm rau cov dej khib nyiab nrog cov khib nyiab siab dua. |
| Phaj spacing (rau phaj settlers) | 80-120 hli | Dav dua txoj kab uas hla. Siv rau siab dua - cov ntawv siv khoom uas cov raj txhaws yuav muaj teeb meem. |
| Tube / phaj ntev | 1.0–1.2 m | Cov raj ntev dua ua rau lub sijhawm nyob thiab txhim kho kev tshem tawm tab sis ntxiv cov nqi thiab cov khoom siv thauj khoom . 1.0 m yog tus qauv tshaj plaws. |
| Lub kaum sab xis | 60 degree | Kev lag luam tus qauv. Ncej txaus rau lub ntiajteb txawj nqus-tsav sludge zawv zawg; ntiav txaus los ua kom tiav qhov projected kab rov tav settling cheeb tsam. |
| Tsis muaj qhov siab | 0.5–1.0 m | Qhov chaw nruab nrab ntawm thaj chaw faib khoom thiab hauv qab ntawm cov hlab. Qhov siab tsis txaus ua rau cov dej tsis sib xws hauv cov hlab ntsha. |
| Ntshiab dej cheeb tsam qhov tob | 0.5–1.0 m | Dej qhov tob tshaj saum cov hlab ntsha. Muab ntim rau txawm sau thiab tiv thaiv luv luv -circuiting mus rau troughs troughs. |
| Lub sijhawm khaws cia - thawj qhov kev daws teeb meem | Tsawg dua los yog sib npaug li 30 min | Rau thawj lub luag haujlwm sedimentation. luv luv dua li cov pa tso tsheb hlau luam (feem ntau 1.5-2.5 teev). |
| Lub sijhawm khaws cia - qhov chaw thib ob | Tsawg dua los yog sib npaug li 60 min | Rau theem nrab (biological) sedimentation. Nco tseg: inclined tube settlers feem ntau tsis pom zoo rau kev lom neeg sludge vim muaj kev pheej hmoo clogging. |
Ob tug qauv tseem ceebtswj cov kev xam sizing:
Qhov chaw saum npoo:
A = Qmax / (0.91 · n · q) (m²)
qha qmaxyog lub siab tshaj plaws tsim ntws, n yog tus naj npawb ntawm cov tso tsheb hlau luam, thiab q yog tus tsim nto loading tus nqi. Qhov txiaj ntsig 0.91 suav rau qhov txo qis hauv cheeb tsam zoo vim yog lub raj phab ntsa tuab thiab cov qauv tsim.
Lub sijhawm khaws cia:
t=(h₂ + h₃) × 60 / q (min)
qhov twg h₂ yog qhov dej tob tshaj qhov chaw inclined tube, h₃ yog qhov dej tob hauv cheeb tsam inclined tube (nce qhov siab ntawm cov raj), thiab q yog qhov chaw thau khoom. Sludge hopper suav ua raws li cov txheej txheem tib yam li cov pa dej hauv cov pa dej.
Daim ntawv ua haujlwm:Txhawm rau tiv thaiv luv luv -circuiting, cov raj inclined yuav tsum tig mus rau qhov kawg ntawm qhov nkag. Sludge tso tawm yog los ntawm lub ntiajteb txawj nqus, feem ntau ib zaug lossis ob zaug hauv ib hnub, nrog cov chaw tu kom huv si rau lub sijhawm yaug ntawm lub raj nplaim.
IV. NYIAJ NYIAJ TXIAV TXIM NTAWM CONVENTIONAL SEDIMENTATION TANKS
1. Laminar flow enables siab dua loading.Tus lej Reynolds qis hauv cov hlab ntsha (Re < 500, feem ntau ~ 50) suppresses turbulence. Particles nyob undisturbed los ntawm eddies. Qhov no yog lub hauv paus hydraulic rau cov neeg nyob hauv lub peev xwm los lis roughly ob npaug ntawm qhov chaw thauj khoom ntawm lub tank pa.
2. Shortened settling nrug txo lub sij hawm.Nyob rau hauv ib tug pa tank, ib tug particle yuav tsum poob los ntawm tag nrho cov dej qhov tob - feem ntau 3-5 meters. Hauv ib lub raj inclined, qhov siab tshaj plaws nyob deb yog lub raj txoj kab uas hla - 50 txog 80 mm. Lub particle ncav cuag qhov kev txiav txim saum npoo ntawm qhov loj dua sai dua.
3. Multiplied settling cheeb tsam ua rau kom muaj peev xwm.Lub tank nrog lub cev hneev taw ntawm 100 m² yuav muaj thaj tsam zoo ntawm 1,000 m² lossis ntau dua, nyob ntawm cov raj geometry, inclination, thiab ntev. Qhov kev sib npaug ntawm thaj chaw no yog qhov laj thawj tseem ceeb ntawm qhov inclined tube settler outperforms qhib lub tank ntawm tib qhov loj.
4. Kev tshem tawm siab nrog lub sijhawm khaws cia tsawg.Kev sib xyaw ua ke ntawm laminar ntws, luv nyob deb, thiab thaj chaw loj loj txhais tau hais tias tus neeg nyob ua tiav 90% + tshem tawm cov khib nyiab tshem tawm ntawm lub sijhawm khaws cia ntawm 30 feeb lossis tsawg dua - piv rau 1.5-2.5 teev rau cov pa kab rov tav - ntws tank.
5. Me hneev taw.Tag nrho cov zoo saum toj no converge ntawm ib qho kev ua tau zoo: lub tank occupies ho tsawg dua av. Rau cov nroj tsuag txwv los ntawm qhov chaw ciam teb - cov chaw kho dej khib nyiab hauv nroog, cov chaw muaj kev lag luam uas txwv tsis pub muaj vaj tse - qhov no feem ntau yog qhov kev txiav txim siab.
