Dab tsi yog Ib Lub Lim Lim Xovxwm? Txoj Cai Ua Haujlwm, Cov Lus Qhia Xaiv & Cov Teeb Meem

Siv lim xovxwm yog siv dav hauv cov chaw kho dej khib nyiab vim lawv cov sludge siab dhau, muaj peev xwm dewatering sai, thiab ua haujlwm tas mus li. Lawv tshwj xeeb tshaj yog haum rau cov nroj tsuag uas yuav tsum tau ceev sludge ntim txo. Cov ntsiab lus noo noo ntawm sludge ncuav mog qab zib tom qab dewatering los ntawm txoj siv lim xovxwm yog feem ntau tsawg dua 80%.

Ib txoj siv lim xovxwm siv ob txoj hlua lim tensioned los nqa ib txheej ntawm sludge los ntawm cov txheej txheem ntawm cov txheej txheem tsis tu ncua hauv S- txoj kev zoo li. Lub nro nyob rau hauv txoj siv tawv ua rau squeezing thiab shearing quab yuam ntawm cov sludge txheej, uas tshem tawm capillary dej thiab tsim ib tug sludge ncuav mog qab zib nrog ib tug siab solids ntsiab lus, yog li ua tiav sludge dewatering.

Feem ntau, siv lub tshuab lim xovxwm muaj cov hlua siv lim, cov menyuam, siv txoj hlua khi, txoj siv hlua khi, txoj siv ntxhua khaub ncaws, thiab siv txoj siv sia.

Sludge Properties:
Ntau hom sludge yuav tsum sib txawv siv lim xovxwm configurations. Cov ntsiab lus tseem ceeb muaj xws li qhov loj me, cov duab, cov ntsiab lus ntawm cov khoom, thiab viscosity. Piv txwv li, siab - viscosity sludge yog zoo dua haum rau siv lim presses nruab nrog yuam rotary scrapers.

Lim Belt:
Txoj siv lim yuav tsum muaj lub zog tensile siab thiab tiv taus qhov kub thiab txias hloov thiab khoov. Txoj siv tawv nruj thiab ceev kuj yog qhov tseem ceeb.

Roller Press Section:
Kev sib raug zoo ntawm lub sijhawm pom thiab lub siab yog qhov tseem ceeb. Ntau dhau los yog ntau cov menyuam yaus tuaj yeem ua rau tsis zoo rau kev ua haujlwm.

Kev xaiv thiab tswj cov khoom siv lim lim, nruj, thiab ceev yog qhov tseem ceeb tshwj xeeb.

Filter Belt Xaiv:
Cov hlua khi yuav tsum muaj lub zog tensile siab, tsis kam khoov, thiab tiv thaiv cov kua qaub, alkalis, thiab kub hloov. Cov khoom tshwj xeeb ntawm cov sludge yuav tsum tau txiav txim siab. Cov qauv weave tsim nyog yuav tsum raug xaiv los ua kom zoo permeability thiab zoo particle tuav.

Filter Belt Tensioning System:
Qhov no feem ntau yog tswj los ntawm pneumatic system. Txoj siv tawv nruj feem ntau khaws cia ntawm 0.3 thiab 0.7 MPa, nrog rau kev khiav hauj lwm tus nqi ntawm ib ncig ntawm 0.5 MPa.

Belt Speed ​​Control:
Ntau hom sludge xav tau txoj siv sib txawv. Rau txhua hom sludge, muaj qhov zoo tshaj plaws ceev ntau yam uas ua kom muaj peev xwm ua tiav thiab sludge ncuav mog qab zib zoo. Txoj siv lim xovxwm yog qhov ua siab ntev ntawm kev hloov pauv ntawm cov khoom thauj, tab sis cov khoom siv ntau dua tuaj yeem ua rau cov dej noo ntau dua hauv cov ncuav mog qab zib sludge.

Kev muaj peev xwm ua tau yog qhov qhia tau tseem ceeb ntawm txoj siv lim xovxwm kev ua haujlwm. Lub thickness ntawm lub ncuav mog qab zib ntub dej yog siv los ua qhov tseem ceeb rau kev suav.

1) Wet Filter Cake Output:

Q_wet_cake=B · ξ · δ · v · S · ·

Qhov twg:
Q_wet_cake - Cov khoom qab zib ntub dej tawm (t/h)
B - Lim siv dav (m)
ξ - Siv dav siv coefficient (feem ntau 0.85–0.9)
δ - Cov ncuav mog qab zib ntub dej tuab (m), feem ntau 0.006–0.01 m
v - Siv ceev (m/min), feem ntau 3–6 m/min
S - Sijhawm factor (60 min/h)
- Qhov ntom ntawm cov ncuav mog qab zib ntub dej (t/m³), feem ntau 1.03
- Tus nqi rov qab, feem ntau ntau dua lossis sib npaug li 95%

2) Sludge Treatment Peev Xwm:

Pub tus nqi=(Cov ntsiab lus ntawm cov ncuav mog qab zib ntub dej / Cov ntsiab lus ntawm cov sludge pub) × Q_wet_cake

3) Tus naj npawb ntawm Siv Lim Xovxwm Yuav Tsum Tau:

n=W / Q_feed_rate

Qhov twg:
n - Tus lej yuav tsum tau ua
W - Tag nrho cov sludge ntim (t/h)
Q_feed_rate - Muaj peev xwm ntawm ib txoj siv lim xovxwm (t / h)

Q1: Dab tsi ua rau lim txoj siv tawv slippage?

Kev siv lub tshuab lim dej feem ntau yog tshwm sim los ntawm kev thauj khoom sludge ntau dhau, siv tsis txaus, flocculant tsub zuj zuj ntawm cov menyuam tsav, cov menyuam hnav, lossis cov menyuam tsis zoo.

Kev daws:
Txo tus nqi noj, xyuas cov pa tawm hauv cov kab pneumatic, kho txoj siv tawv nruj, tshuaj xyuas cov menyuam rau kev hnav lossis kev sib hloov tsis zoo, thiab txhim kho lubrication.
