Yuav ua li cas los tsim thiab xam lub tube settler?
-Cov lus piav qhia ntawm Honeycomb Tube Settler Sedimentation Tank
Raws li lub hauv paus ntsiab lus ntawm sedimentation, ntawm ib tug tej yam txaus nqi q thiab ib tug tej yam particle sedimentation tshaj tawm u Nyob rau hauv cov xwm txheej ntawm, sedimentation efficiency e yog proportional rau lub dav hlau cheeb tsam ntawm lub pas dej ua ke, piv txwv li E=UA/Q. Lub pas dej ua ke tau muab faib ua n ntu ntu hauv qhov siab, uas ua rau thaj tsam dav hlau ntawm lub pas dej ua ke, ua kom lub sij hawm daws teeb meem thiab txhim kho kev daws teeb meem.
Ua ke nrog kev xav tau ntawm sludge tawm, lub phaj inclined ntxiv rau lub inclined phaj sedimentation tank, uas ua rau kom cov dej ntws thiab qhov chaw ntub dej ntawm lub tank, txo cov hydraulic vojvoog, txo Reynolds tus naj npawb thiab turbulence ntawm cov dej ntawm tib txoj kab rov tav. tus nqi, thiab muaj zoo sedimentation nyhuv.
Inclined tube sedimentation tank yog lub tank sedimentation nyob rau hauv uas muaj ntau qhov sib npaug inclined hlab nrog me me ntu tau nruab. Lub hauv paus ntsiab lus ntawm sedimentation ntawm inclined tube sedimentation tank yog tib yam li ntawm inclined phaj sedimentation tank. Ntawm hydraulic mob, lub vojvoog hydraulic ntawm inclined raj yog me dua li ntawm cov phaj inclined, yog li Reynolds tus lej qis dua thiab cov nyhuv sedimentation yog qhov zoo tshaj plaws. Inclined tube sedimentation tank muaj peev xwm me me thiab txuag chaw hauv pem teb.Nws tau txais los ntawm ntau cov nroj tsuag dej hauv tsev thiab txawv teb chaws thiab tau txais kev paub ntau hauv kev ua haujlwm thiab kev tswj xyuas. Qhov teeb meem yog tias kev saib xyuas thiab kev tswj xyuas yog qhov nyuaj, thiab cov phaj inclined ntawm cov kav dej inclined yuav tsum tau ntxuav thiab hloov tsis tu ncua. Vim lub sij hawm luv luv ntawm inclined phaj thiab inclined tube sedimentation tank, kev saib xyuas thiab kev tswj xyuas yuav tsum tau ntxiv dag zog thaum dej kom muaj nuj nqis thiab cov dej zoo hloov thaum lub sijhawm ua haujlwm.Thaum siv hom sedimentation tank, kev saib xyuas yuav tsum tau them rau qhov zoo tshaj plaws ntawm flocculation thiab tsim nyog kev npaj ntawm sludge tawm.
(1) Tsim cov ntsiab lus ntawm Inclined Phaj Sedimentation Tank.
① Muaj peb lub ntsiab dej ntws cov lus qhia nyob rau hauv inclined phaj sedimentation tank: nce siab, ntws ntws thiab downward flow.
② Tus tsim particle daws qhov nrawm μ ntawm inclined phaj sedimentation tank, thiab cov kua theem load yuav tsum tau txiav txim siab los ntawm kev sim lossis xa mus rau kev ua haujlwm ntawm cov dej ua haujlwm hauv cov xwm txheej zoo sib xws. Tus tsim particle daws qhov nrawm tuaj yeem yog {{0}}.16 ~ 0.3mm / s, cov kua theem load tuaj yeem yog 6.0 ~ 12 m / (mh), thiab tus nqi qis dua yuav tsum tau txais yuav rau qhov kub thiab txias tsis tshua muaj dej turbidity.

Ces
9. Txheeb xyuas cov khoom hnyav.
Ua tau raws li cov kev xav tau ntawm cov khoom thauj khoom.
③ Inclination angle o: Nws txawv raws li cov ntaub ntawv thiab cov khoom ntawm cov phaj inclined, thiab nws feem ntau yog 60 rau qhov yooj yim ntawm cov av nkos.
④ phaj nrug p: uas yog, qhov kev ncua deb ntawm ob daim hlau inclined, thiab lateral flow inclined phaj p yog feem ntau 80 ~ 100mm; Qhov ntev ntawm ib txheej inclined phaj yuav tsum tsis txhob ntau tshaj 1.0m.
⑤ tshaj tawm v hauv phaj: xam raws li qhov chaw thauj khoom thaum ntws los; Cov dej ntws sab nraud tuaj yeem xa mus rau kab rov tav tshaj tawm sib npaug rau kab rov tav sedimentation tank, uas feem ntau yog
10 ~ 20mm / s; Thaum ntws downwards, nws muaj peev xwm xam tau raws li lub downward nto load.
⑥ Nyob rau hauv lub pas dej ua ke ntawm lateral flow inclined phaj, nyob rau hauv thiaj li yuav tiv thaiv cov dej los ntawm inclined phaj, yuav tsum tau teem ib tug choke phab ntsa, thiab lub sab saum toj ntawm inclined phaj yuav tsum siab tshaj cov dej nto.
⑦ Txhawm rau faib thiab sib sau cov dej sib npaug, qhov nkag thiab qhov hluav taws xob ntawm cov phaj inclined sedimentation tank nyob rau sab nraud yuav tsum tau muab cov phab ntsa rectifying. Qhov qhib tus nqi ntawm cov phab ntsa rectifying ntawm lub inlet yuav tsum yog xws li tias qhov khiav ceev ntawm lub qhov yog tsis ntau tshaj qhov khiav ceev ntawm lub qhov hluav taws xob ntawm lub flocculation tank, thiaj li tsis txhob floc breakage.
⑧ Punched yeeb nkab lossis cov khoom siv hluav taws xob sludge tawm feem ntau yog siv, thiab tsim cov yeeb nkab perforated sludge tawm yog tib yam li cov dej hauv lub tank.
(2) Cov ntsiab lus tseem ceeb ntawm inclined yeeb nkab txheej txheem tsim
