Khoom Description
CovEPDM diffuser daim nyias nyiasmuaj nyob rau hauv daim ntawv diaphragm disc. Nws yog ib yam tshiab ntawm microporous aeration ntaus ntawv siv nyob rau hauv kev kho mob ntawm industrial wastewater thiab municipal dej phwj tuaj. Nws nta lub peev xwm loj huab cua, tsis muaj lub taub hau poob, muaj peev xwm nqa tau zoo, thiab ua haujlwm siab oxygenation.
Ntau tus micropores raug faib rau ntawm diaphragm. Thaum huab cua nkag, cov pores qhib los ua npuas zoo; Thaum cov khoom cua nres, cov pores kaw cia li. Qhov no tiv thaiv cov dej phwj tuaj thiab cov khib nyiab los ntawm kev nkag mus rau hauv lub raj xa cua thiab txhaws lub aerator.
EPDM diffuser daim nyias nyias yog corrosion-resistant thiab oxidation-resistant, thiab muaj qhov zoo ntawm lub teeb yuag, siab zog, nplua thiab zoo npuas tsim, thiab tiv thaiv kom txhaws. Nws yog tshwj xeeb tshaj yog siv nyob rau hauv ozone aeration daim ntaub ntawv. Microporous aerators tau siv dav hauv ozone tshuaj tua kab mob rau cov dej haus thiab cov dej rov qab siv dua, aeration hauv cov dej phwj tuaj kho, thiab oxygenation hauv cov txheej txheem fermentation.
Nws yog cov cuab yeej tseem ceeb rau lub tshuab cua tshuab -raws li aeration thiab oxygenation systems. Kev xaiv cov cuab yeej aeration tsis tsuas yog cuam tshuam rau biochemical kev ua tau zoo ntawm cov dej phwj tuaj tab sis tseem cuam tshuam rau thaj av xav tau, peev peev, thiab cov nqi khiav lag luam ntawm cov chaw kho dej khib nyiab.
Lub diffuser nta ib lub npuas me me, ib lub me me roj-kua interface txoj kab uas hla, ib tug loj roj-kua cheeb tsam sib cuag, uniform npuas tis, tsis kam mus rau pore blockage, thiab muaj zog corrosion kuj. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov chaw kho dej hauv nroog, loj- cov chaw tsim khoom loj hauv kev tsim kho tshiab lossis nthuav dav, thiab kev kho dua tshiab ntawm cov tso tsheb hlau luam uas twb muaj lawm. Lub aeration tank tuaj yeem ua haujlwm tsis tu ncua.
Precision drilling ua kom muaj txiaj ntsig oxygen xa mus thiab siv:
Txhawm rau ua kom tau raws li qhov yuav tsum tau muaj ntawm cov tshuab aeration sib txawv, ntau cov qauv drilling tuaj yeem siv los kho kev khiav hauj lwm siab, nrog rau qhov sib txawv qhov ntev, qhov sib txawv, thiab qhov tob tob. Txoj kab uas hla drilling yog nyob ntawm184-295 hli. Ntau yam txheej txheem thiab cov ntaub ntawv tshwj xeeb membrane yog tsim kom haum rau ntau yam kev siv.
Membrane cov ntaub ntawv muaj xws li:
EPDM:Haum rau cov dej khib nyiab hauv nroog
Tsawg-plasticizer EPDM:Haum rau kev lag luam dej khib nyiab los ntawm kev tua tsiaj, kev ua zaub mov, thiab kev tsim dej haus
Tag nrho cov ntaub ntawv membrane yog tsim los siv cov thev naus laus zis siab heev los tiv thaiv qhov chaw clogging, khoom deposition, lom fouling, thiab crust tsim.
Lub microporous aeration disc txais kev tsim qauv. Nws lub cev tseem ceeb muaj ob npaug - txheej txheej txheej txheej tsim los ntawm ABS engineering yas txhawb nqa ncej thiab EPDM roj hmab diaphragm. ABS thav duab yog tsim rau hauv lub cev pob txha txhawb nqa honeycomb los ntawm kev txhaj tshuaj molding, muab lub zog compressive txog li.12 kN/m². Nws kuj tseem muaj cov qauv tsim, nrog rau ib qho -disc hnyav ntawmTsawg dua los yog sib npaug li 1.2 kg.
Lub EPDM diaphragm yog nruj nreem khi rau txoj kev txhawb nqa los ntawm cov txheej txheem kub - nias. Laser- txiav micropores nrog txoj kab uas hla80–100 μmyog uniformly faib thoob qhov chaw, nrog ib tug pore ntom ntawm3,000-4,000 qhov/m². Lub diaphragm ntug tau txais ob npaug - txheej sealing nplhaib tsim ua ke nrog ob txoj kev sib txuas ntawm lub qhov (socket), uas ua rau nws tuaj yeem tiv taus huab cua tsis tu ncua raws li kev ua haujlwm siab ntawm0.03 MPa.
Tus tsim tshwj xeeb rau tus kheej -kaw pore qauv cia li kaw thaum aeration nres. Hauv kev sib xyaw nrog silicone-cov hlua txuas ntxiv (tuag tsis kamNtau tshaj lossis sib npaug li 25 kN / m), qhov tsim no zoo tiv thaiv diaphragm deformation thiab intrusion ntawm impurities. Zuag qhia tag nrho, cov qauv sib npaug txhua yam muaj zog thiab elastic deformation muaj peev xwm, nteg lub hauv paus ruaj khov rau kev ua tiav cov pa oxygen hloov pauv tau zoo thiab tiv thaiv corrosion.
Tus yuam sij rau kev txhim kho kev siv cov pa oxygen hauv microporous aeration discs yog nyob rau hauv optimizing gas diffusion efficiency thiab npuas nyob hauv lub sij hawm. Vim nws siab elasticity, EPDM roj hmab diaphragm nthuav dav uniformly thaum lub sij hawm aeration, tsim microbubbles nrog diameters ntawm0.5-2 hli. Qhov no ua rau cov roj-kua sib cuag cheeb tsam ntau dua40%piv nrog cov pa aeration khoom.
Laser txiav kom lub pore txoj kab uas hla raug nyob rau hauv±5 μmthiab pore spacing kam rau hauv0.2 hli, ua rau muaj kev sib txuam ua npuas ntau. Los ntawm kev kho lub aeration disc inclination lub kaum sab xis (pom zoo5℃-8 degree) thiab aeration siv (0.05–0.15 m³ / min·m²), txoj kev npuas nce tuaj yeem txuas ntxiv mus1.2–1.8 m, ua kom cov pa oxygen hloov mus rau qhov tseem ceeb ntawm tus nqi35%.
Thaum lub sij hawm kev teeb tsa, lub siab - ntsuas qhov tsim rau lub aeration network yuav tsum tau ua. Qhov sib txawv - txoj kab uas hla ceg yeeb nkab system (maj mam hloov ntawmDN25 rau DN50) raug pom zoo kom tswj lub siab sib txawv ntawmTsawg dua lossis sib npaug li 50 Panruab nrab ntawm aeration units, yog li tshem tawm hauv zos tshaj - aeration los yog hauv qab - aeration. Thaum ua haujlwm, a3: 1 intermittent aeration homyog pom zoo kom coj kom zoo dua ntawm qhov thib ob shear nyhuv generated los ntawm npuas vau, ntxiv txhim kho oxygen dissolution efficiency.
Qhov taw qhia tseem ceeb rau Installation Flatness Control
Hauv kev tsim kho, qhov flatness ntawm lub tank hauv qab ncaj qha cuam tshuam rau huab cua kev ua haujlwm thiab kev pabcuam lub neej ntawm microporous aeration disc. Engineering specifications xav tau kab rov tav sib txawv ntawm lub tank lub hauv paus kom nruj tswj nyob rau hauvTsawg dua los yog sib npaug li 3 mm / m. Cov pab pawg tsim kho feem ntau siv cov cuab yeej laser qib ua ke nrog cov tshuaj khib nyiab kom ua tau ntau yam - kev taw qhia calibration thoob plaws ntau qhov chaw.
Qhov pom zoo sib nrug ntawm cov kav kav dej yog800-1,000 hli. Kev sib nrug ntau dhau tuaj yeem ua rau thaj chaw aeration dig muag, thaum qhov sib txawv uas nqaim dhau tuaj yeem ua rau muaj kev cuam tshuam ntawm huab cua. Rau kev sib txuas cov yeeb nkab, ob - lub qhov (socket) qauv yuav tsum dhau a0.2 MPa siabkev ntsuas siab los xyuas kom meej tias qhov cuam tshuam qhov cuam tshuam tsawg dua1.5%.
Nws yuav tsum tau muab sau tseg tias cov khoom ntse los yog sediment txheej dhau lawm5 hlinyob rau hauv thickness ntawm lub tank hauv qab tuaj yeem ua rau muaj kev ntxhov siab tsis sib xws ntawm lub diaphragm, ua kom qaug zog tawg ntawm cov khoom siv roj hmab.
