Taw qhia
Xaiv qhov tseeb submersible tov khoom yog ib feem tseem ceeb ntawm kev kho dej khib nyiab tsim.
Ib lo lus nug pib feem ntau yog:
"Kuv xav tau pes tsawg watts ib cubic meter?"
Lub zog ceev, lossis W / m³, tuaj yeem pab tau rau kev kwv yees ua ntej. Txawm li cas los xij, nws yuav tsum tsis txhob siv los ua tib lub hauv paus rau kev xaiv zaum kawg tov khoom.
Tib lub zog lub cev muaj zog tuaj yeem tsim cov hydraulic sib txawv nyob ntawm tus qauv impeller, txoj kab uas hla, kev sib hloov ceev, thiab lub tank.
Vim li no, kev xaiv cov dej khib nyiab yuav tsum xav txog ob qho tib silub zog thiab kev ua haujlwm hydraulic.
1. Xam lub Tank Volume
Thawj kauj ruam yog los txiav txim siab qhov kev khiav hauj lwm ntim.
Rau lub tank rectangular:
Volume=Length × Dav × Dej Qhov tob
Piv txwv:
20 m × 10 m × 4 m
= 800 m³
Lub ntim ua haujlwm tau zoo yuav tsum tau siv ntau dua li qhov yooj yim nominal structural ntim.
2. Nkag siab W/m³
Lub zog ceev tuaj yeem xam raws li:
P/V=Tov Khoom Fais Fab ÷ Siv Tau Tank Volume
Piv txwv li:
Lub zog sib tov=4 kW
Lub tank ntim=800 m³
Yog li ntawd:
4 ÷ 800=0.005 kW/m³
los yog:
5 W/m³
Tus nqi no tuaj yeem pab tau rau kev sib piv cov qauv tsim ua ntej.
Txawm li cas los xij,5 W / m³ tsis tau txhais hais tias lub tov khoom haum rau txhua 800 m³ tank.
Vim li cas?
Vim hais tias tank geometry thiab hydraulic tej yam kev mob yuav txawv heev.
3. Kev sib xyaw ua ke yog qhov tseem ceeb
Lub cev muaj zog qhia koj lub zog hluav taws xob ntau npaum li cas lub cev muaj zog siv.
Nws tsis tau piav qhia txog kev ua haujlwm hydraulic ntawm lub tov khoom.
Rau kev siv dej khib nyiab, tov khoom thrust yog ib qho tseem ceeb parameter vim hais tias nws qhia lub zog hydraulic tsim los ntawm lub kiv cua los yog impeller.
Thaum sib piv mixers, engineers yuav tsum xyuas:
Lub cev muaj zog
Mixer zog
Impeller txoj kab uas hla
Kev sib hloov ceev
Hydraulic efficiency
Flow yam ntxwv
Lub siab- lub zog sib tov nrog cov khoom siv hydraulic tsis zoo yuav tsis tas muab kev sib xyaw zoo dua li qhov tsim nyog qis dua - lub zog tov khoom.
4. Tank Geometry txiav txim qhov Flow Pattern
Xav txog ob lub tank nrog tib lub ntim:
Tank A: 10 × 10 × 4 m = 400 m³
Tank B: 20 × 5 × 4 m = 400 m³
Txawm hais tias ob leeg muaj 400 m³, lawv cov yam ntxwv hydraulic txawv.
Lub tank ntev - txog - qhov dav qhov sib piv, qhov chaw nkag thiab qhov hluav taws xob, cov qauv sab hauv, thiab dej qhov tob tuaj yeem cuam tshuam rau kev ncig.
Yog li ntawd:
Tib ntim ≠ Tib tov khoom configuration
Tus naj npawb thiab txoj hauj lwm ntawm cov khoom sib tov yuav tsum raug xaiv raws li qhov yuav tsum tau ua raws li qhov yuav tsum tau ua.
5. MLSS thiab cov yam ntxwv ntawm cov dej khib nyiab
Cov dej khib nyiab tsis yog dej huv.
Activated sludge feem ntau yuav muaj kwv yees li:
2,500–3,500 mg/L MLSS
nyob ntawm tus txheej txheem.
Cov khib nyiab ntau dua tuaj yeem cuam tshuam cov kev xav tau ntawm kev ncua thiab kev coj tus cwj pwm hydraulic.
Lwm cov yam ntxwv kuj tseem yuav cuam tshuam, suav nrog:
Sludge concentration
Kub
Cov dej khib nyiab viscosity
Muaj cov ntaub ntawv fibrous
Tank txheej txheem hom
Yuav tsum sib tov lub hom phiaj
Cov yam tseem ceeb no yuav tsum tau txiav txim siab thaum xaiv lub tshuab tov khoom.
6. Txiav txim siab lub hom phiaj ntawm kev sib tov
Lub tov khoom yuav tsum raug xaiv raws li nws lub hom phiaj tiag tiag.
Anoxic tank
Lub hom phiaj tseem ceeb:
Khaws MLSS ncua
Tswj kev ncig
Txhawb kev sib cuag ntawm nitrate, carbon qhov, thiab biomass
Tsis txhob hloov cov pa oxygen uas tsis tsim nyog
Anaerobic tank
Lub hom phiaj tseem ceeb:
Txhim kho cov khoom tawg yooj yim
Txhawb cov xwm txheej zoo ib yam
Tsis txhob siv cov pa oxygen tsis xav tau
Equalization tank
Lub hom phiaj tseem ceeb yuav suav nrog:
Tiv thaiv kom tsis txhob muaj khib nyiab
Homogenize dej khib nyiab
Txo cov concentration hloov pauv
Oxidation ditch
Cov khoom sib tov tuaj yeem siv los txhawb kev txuas mus tas li los ntawm kev kho cov channel.
Cov ntawv thov sib txawv yog li ntawd yuav xav tau cov khoom sib xyaw sib txawv.
7. Txheeb xyuas tus naj npawb thiab qhov chaw ntawm cov khoom sib tov
Ib qho yuam kev feem ntau yog xaiv lub tov khoom ua ntej thiab txiav txim siab qhov kev teeb tsa tom qab.
Txoj kev zoo tshaj yog:
Tank geometry → Hydraulic yuav tsum tau → Tov khoom thrust → Tov khoom kom muaj nuj nqis → Installation txoj hauj lwm
Ntau qhov sib tov yuav xav tau rau cov tank loj lossis tsis sib xws.
Installation yuav tsum xav txog:
Kev taw qhia ntws
Tank partitions
Qhov chaw nkag
Qhov chaw qhov hluav taws xob
Dej tob
Kev cuam tshuam
Yuav tsum muaj txoj kev ncig
Lub hom phiaj yog kom tsis txhob muaj chaw nyob ruaj khov thiab ua kom muaj kev txaus txaus thoob plaws hauv lub ntim zoo.
Cov ntaub ntawv dab tsi koj yuav tsum muab rau tus neeg muab khoom sib tov?
Rau kev xaiv qhov sib tov ua ntej, koj tuaj yeem sim muab:
Tank ntev
Tank dav
Kev khiav dej num qhov tob
Siv tau lub tank ntim
MLSS concentration
Hom dej khib nyiab
Lub hom phiaj sib xyaw
Tus naj npawb ntawm cov tank

Kev txwv kev teeb tsa
Yog muaj, kuj muab:
Txheej txheem flow diagram
Tank kos duab
Cov khoom siv uas twb muaj lawm
Yuav tsum tau kev kho mob
Cov duab ntawm lub tank
Nrog rau cov ntaub ntawv no, tus kws tshaj lij tuaj yeem ntsuas qhov tsim nyog lub zog sib xyaw ua ke, thawb, kom muaj nuj nqis, thiab teeb tsa kev teeb tsa.
Submersible Mixer Khoom / Daim Ntawv Thov
Submersible mixers feem ntau yog siv rau anoxic tso tsheb hlau luam, anaerobic tso tsheb hlau luam, oxidation ditches, equalization tso tsheb hlau luam, thiab lwm yam kev siv dej khib nyiab yuav tsum tau mus tas li ncig thiab cov khib nyiab ncua.
Raws li qhov yuav tsum tau ua ntawm qhov project, tov khoom configurations tuaj yeem hloov kho rau yam xws li:
Stainless hlau tsim
Corrosion kuj
Voltage thiab zaus
Cable ntev
Lub cev muaj zog rwb thaiv tsev chav kawm

Txoj kev teeb tsa
Rau qhov project-kev xaiv tshwj xeeb, lub tank qhov ntev thiab kev ua haujlwm yuav tsum raug tshuaj xyuas ua ntej pom zoo rau tus qauv.
FAQ
Yuav ua li cas kuv xam submersible mixer zog?
Kev suav ua ntej tuaj yeem siv lub zog ceev:
P/V=Tov Khoom Fais Fab ÷ Siv Tau Tank Volume
Txawm li cas los xij, W / m³ yuav tsum tsuas yog siv raws li kev siv ua ntej. Kev xaiv zaum kawg yuav tsum xav txog kev sib tov sib xyaw, tank geometry, MLSS, impeller yam ntxwv, thiab hydraulic yuav tsum.
Puas yog W/m³ txaus los xaiv lub tshuab ntxhua khaub ncaws?
Tsis yog. W/m³ yog qhov tseem ceeb rau kev sib piv ua ntej, tab sis nws tsis piav qhia txog kev ua haujlwm hydraulic ntawm lub tov khoom.
Vim li cas qhov sib xyaw thrust tseem ceeb?
Thrust qhia tias lub zog hydraulic tsim los ntawm cov khoom sib tov thiab pab cov engineers ntsuas nws lub peev xwm los tsim kev ncig thiab tswj cov khoom tawg.
Muaj pes tsawg mixers xav tau ib lub tank dej khib nyiab?
Tsis muaj tus lej universal. Qhov xav tau kom muaj nuj nqis nyob ntawm lub tank geometry, ntim tau zoo, kev sib xyaw ua ke, kev teeb tsa, thiab cov qauv kev xav tau.
Puas yog ib lub tshuab tov siv tau rau kev siv dej khib nyiab sib txawv?
Muaj peev xwm, tab sis tus qauv thiab kev teeb tsa yuav tsum raug ntsuas raws li cov ntawv thov tshwj xeeb. Lub tank anoxic, lub tank sib npaug, thiab oxidation ditch tej zaum yuav muaj kev sib xyaw sib txawv.
Xaus
Submersible mixer xaiv yuav tsum tsis txhob raug txo rau ib tus lej W / m³.
Ib qho kev xaiv txhim khu kev qha suav nrog:
