Taw qhia rau lim cartridges hauv cov khoom siv kho dej ntshiab

Filter cartridges yog cov txheej txheem tseem ceeb ntawm kev kho dej ntshiab huv. Lawv cuam tshuam cov impurities, tiv thaiv cov cuab yeej, thiab txhim kho cov dej zoo. Raws li cov khoom siv tseem ceeb hauv cov cuab yeej siv dej ntshiab, lawv yuav tsum tau hloov kho kom raws sijhawm thiab kev saib xyuas thaum ua haujlwm txhua hnub. Shanghai Quanrui, tsim nyob rau hauv 2010, muaj ntau xyoo ntawm kev paub nyob rau hauv cov dej ntshiab cov cuab yeej tu cov kev pab cuam. Cov hauv qab no yog kev taw qhia txog precision lim cartridges hauv cov khoom siv dej ntshiab:

I. Lub luag haujlwm tseem ceeb ntawm Precision Lim Cartridges

Lub luag haujlwm tseem ceeb ntawm precision lim cartridges yog:
1. Kev cuam tshuam lub cev: Tshem tawm cov khoom tshem tawm, colloids, kab mob, xeb, thiab lwm yam impurities los ntawm dej (filtration precision feem ntau yog 1-50 microns);
2. Tiv thaiv cov khoom siv hauv qab: Tiv thaiv cov khoom tseem ceeb xws li RO rov qab osmosis membranes thiab ion exchange resins los ntawm clogging los yog kev puas tsuaj vim muaj paug;
3. Txhim kho dej kom ruaj khov: Ua kom cov dej nkag mus rau hauv cov txheej txheem kho tseem ceeb ua tau raws li qhov yuav tsum tau ua, ua kom lub neej ntev ntawm cov cuab yeej siv thiab txo cov nqi tu.

II. Yam khoom thiab yam ntxwv

PP paj rwb (polypropylene): Melt- qauv tshuab, qhov pore loj 5-20 microns, tus nqi qis, haum rau kev pom ntxhib, hloov tau yooj yim, tab sis nrog cov tshuaj tsis muaj zog.

Activated carbon lim cartridge: Cov qauv sib xyaw (PP + activated carbon), adsorbs residual chlorine thiab organic teeb meem, txhim kho saj, feem ntau siv hauv cov zaub mov / tshuaj pretreatment.

Cov iav fiber ntau: Kub thiab corrosion resistant, pom tseeb 1-10 microns, haum rau siab turbidity dej los yog kub kub ib puag ncig.
PES (Polyethersulfone): Highly hydrophilic, acid thiab alkali resistant, pom tseeb 0.1-1 micron, siv rau ultrafiltration pretreatment, feem ntau pom nyob rau hauv kev lag luam biopharmaceutical.

PVDF (Polyvinylidene fluoride): Cov khoom siv hydrophobic, tiv taus fouling thiab oxidation, haum rau cov dej khib nyiab pretreatment uas muaj cov organic teeb meem lossis roj.

III. Hloov Cov Ntsiab Cai

1. Differential Pressure Monitoring: Qhov sib txawv ntawm qhov nkag / qhov hluav taws xob siab tshaj 0.1-0.15 MPa (saib rau hauv phau ntawv qhia cov khoom siv rau cov nqi tshwj xeeb) qhia tias muaj cov lim lim loj heev.
2. Flow Rate: Cov dej ntau lawm poob mus rau 60% -70% ntawm nws cov nqi pib, cuam tshuam rau kev ua haujlwm zoo.
3. Kev Ntsuas Dej Zoo: Ntau dhau turbidity los yog SDI (Soil Degradation Index) nyob rau hauv cov effluent, los yog ib tug tseem ceeb txo nyob rau hauv lub desalination tus nqi ntawm cov khoom downstream (xws li RO membranes).
4. Kev hloov lub voj voog: Tus qauv hloov lub voj voog yog 3-6 lub hlis, tab sis yuav tsum tau hloov kho raws li qhov dej zoo (xws li dej saum npoo av / dej hauv av).
5. Kev tshuaj xyuas qhov muag: Lim cov ntsiab lus uas pom tseeb tsis muaj xim, deformation, lossis tawg yuav tsum tau hloov tam sim ntawd.

IV. Hloov Txoj Kev (Cov txheej txheem txheej txheem)

1. Kev npaj kaw: Kaw lub inlet valve, nres lub siab - lub twj tso kua mis siab, thiab qhib lub valve kom tso siab rau atmospheric siab.

Hnav cov hnab looj tes tiv thaiv thiab tsom iav kom tsis txhob sib cuag nrog cov dej khib nyiab.

2. Tshem tawm Cov Lim Lim Cov Laus: Siv ib lub dab teg tshwj xeeb kom tshem tawm cov lim tsev nyob ua ke, tshem tawm cov lim dej qub, thiab xyuas cov phab ntsa sab hauv ntawm cov khoom lim dej rau cov khoom seem seem. 1. Sau tus qauv naj npawb, hloov hnub, thiab txhaws cov txheej txheem ntawm cov lim qub (muab cov duab rau cov ntaub ntawv- khaws cia).

2. Nruab lub lim tshiab. Ntxuav sab hauv ntawm lub tsev lim, hloov O- nplhaib foob, thiab siv cov roj silicone rau lubrication.

Nco ntsoov qhov taw qhia: Qhov kawg nrog lub nplhaib sib khi yuav tsum tig mus rau sab saud. Xyuas kom lub lim dej ua raws li lub hauv paus raj ntawm lub lim tsev (tsis txhob misalignment ua rau to).

Tom qab phau ntawv ua ntej-tightening, zawm nrog lub torque ciaj ntswj raws li tus neeg tsim khoom yuav tsum tau (xws li, 30-40 N·m) kom tiv thaiv overtightening thiab puas rau cov xov.

3. Kev kho qhov system thiab dej ntws tawm. Maj mam qhib lub inlet valve kom tshem tawm cov pa tawm ntawm cov kav dej. Flush ntawm qhov tsis tshua muaj siab rau 10-15 feeb kom tshem tawm cov dej tiv thaiv thiab cov khoom ntawm cov lim dej. Ntsuam xyuas cov dej tsis zoo (piv txwv li, siv lub ntsuas ntsuas turbidity thiab conductivity meter). Thaum paub tseeb tias ua tau raws li cov qauv, rov pib ua haujlwm.

4. Hloov cov ntaub ntawv. Hloov kho cov cuab yeej tu cav, sau cov lim caij batch naj npawb, hloov lub sij hawm, thiab pib qhov sib txawv siab tus nqi rau kev taug qab yav tom ntej.

5. Ceev faj. Pretreatment optimization: Yog tias nquag clogging, xyuas lub pre- lim los yog ntxiv flocculant los txhim kho cov dej zoo. Kev pov tseg pov tseg: PP paj rwb lim cartridges yuav tsum muab pov tseg raws li kev pov tseg; Cov lim cartridges uas muaj cov hlau hnyav hnyav yuav tsum tau muab pov tseg raws li cov cai pov tseg pov tseg.

Los ntawm kev hloov pauv thiab kev saib xyuas, cov ntawv lim dej lim tau zoo tuaj yeem txhim kho kev ntseeg tau thiab kev lag luam ntawm cov dej ntshiab huv.
