1, kev npaj ntawmPAM flocculantkev daws: hauv kev siv, yuav tsum yaj, tom qab ntawd siv, kom yaj tag, ntxiv rau cov dej khib nyiab ntawm cov concentrator. Tsis txhob muab pov tseg cov khoom polyacrylamide ncaj qha rau hauv cov kav dej phwj tuaj, nws yuav ua rau cov tshuaj pov tseg zoo, nce nqi kho mob.
2, PAM floctant dissolution mob kub thiab PH tus nqi: nyob rau hauv lub dissolution, yuav tsum tau yaj nyob rau hauv dej nyob rau hauv chav tsev kub, muaj zog acid, alkali, siab concentration, siab ntsev, kub siab dej khib nyiab tsis haum rau dissolution ntawm polyacrylamide, cov dej zoo. yuav cuam tshuam rau kev siv polyacrylamide ntawm floccoagulation nag lossis daus.Nws yuav tsum raug sau tseg tias cov dej kub tsis tuaj yeem tshaj 50 degrees Celsius thaum polyacrylamide yaj. Cov dej kub ntau dhau yuav txhawb nqa thermal degradation ntawm polyacrylamide, yog li cuam tshuam rauflocculationthiab cov nyhuv sedimentation.
3, kev xaiv ntawm polyacrylamide configuration thawv: nyob rau hauv lub dissolution tank, dissolution tank yuav ntws tawm ntawm ib tug tej qhov chaw, kom tsis txhob dissolution ntawm lub stirring ntaus ntawv ntau dhau lawm, cov kua yuav raug pov tseg, uas ua rau cov khib nyiab.
4, PAM flocculanttov configuration ratio: nyob rau hauv lub dissolution ntawm lub configuration piv feem ntau yog 1‰-3‰.Ntawd yog, ib tuj dej, nrog 1kg ntawm cov khoom polyacrylamide hais. Yog tias qhov concentration loj dhau lawm, nws yuav ua rau lub sijhawm tawg sai dhau thiab lub sijhawm tawg yuav ntev dhau. Yog tias qhov concentration ntawm kev teeb tsa tsawg dhau, nws yuav ua rau cov neeg ua haujlwm ntau zaus. Thaum lub concentration ntawm cov dej khib nyiab uas tau xaiv yog siab dhau lawm, qhov tsis tshua muaj siab ntawm cov kua polyacrylamide tsis tuaj yeem ua tau raws li kev kho mob, uas ua rau kev kho dej tsis zoo.
5, kev npaj tov yuav tsum tau tas li stirred: cov txheej txheem ntawm tig rau ntawm stirrer rau stirring.Ncuav qhov hnyav polyacrylamide sib npaug thiab raws li qhov tsim nyog ntawm ntug ntawm lub viav vias ua los ntawm nplawm. Yuav tsum tsis txhob nchuav sai rau hauv ib zaug, qhov no yuav tsim ntau "ntses qhov muag", cov "ntses qhov muag" yog polyacrylamide ntau cov dej tshwm sim los ntawm ib zaug ncuav, cov "ntses qhov muag" no nyuaj heev. kom yaj, yog li tsis yog tsuas yog pov tseg cov tshuaj, tseem yuav ua rau cov yeeb nkab thaiv.
6,stirring ceev: qhov linear ceev ntawm qhov kawg ntawm rab riam yuav tsum tsis txhob ntau tshaj 8 m / s, thiaj li tsis ua rau polyacrylamide degradation.Lub stirring ceev yuav tsum tsis txhob tsawg dhau, yog li tsis txhob ncua cov polyacrylamide hais rau ntawm cov dej saum npoo av, thiaj li ua kom yaj cov agglomerates thiab ua rau kom qhov nyuaj ntawm dissolution.
7, sib tov lub sij hawm: polyacrylamide yuav tsum tau stirred rau ntau tshaj li ib nrab ib teev kom tag nrho yaj, thaum tsis muaj dawb micelle nyob rau hauv lub mixing tank, polyacrylamide yog ib txwm yaj tag.
8, tsuas yog yaj tag nrho PAM flocculant, thiaj li ua si nws tus kheej qhov siab tshaj plaws flocculation nag lossis daus. Yog li ntawd, thaum siv, lub tshuab nplawm yuav tsum tau qhib txhua lub sijhawm, uas tuaj yeem tsis tsuas yog ua kom tiav qhov kev sib cais ntawm polyacrylamide, tab sis kuj ua rau kom lub siab mus rau cov yeeb nkab raj, ua kom cov dej ntws tawm ntawm cov tshuaj.
9, kev teeb tsa ntawm PAM flocculant tov, tsis tuaj yeem siv lub twj tso kua mis centrifugal hloov mus, kom tsis txhob muaj kev sib hloov ceev ntawm cov hniav tshwm sim los ntawm shear degradation ntawm polyacrylamide.
10, cov tshuaj polyacrylamide yuav tsum tau siv tam sim no, hnub ntawm kev teeb tsa ntawm cov kev daws teeb meem zoo, nws yog qhov zoo tshaj plaws los siv li ntawm 48 teev. Yog tias cov tshuaj polyacrylamide muab tso rau lub sijhawm ntev, nws cov flocculation thiab nag lossis daus yuav maj mam txo.
11, tom qab noj cov PAM flocculation tus neeg sawv cev, lub hnab ntim polyacrylamide yuav tsum tau khi tam sim ntawd, tsis tuaj yeem cia nws ntub dej, raug tshav ntuj thiab tiv thaiv huab cua rau lub sijhawm ntev, yog li nws yooj yim los ua polyacrylamide hydrolysis, tsis ua haujlwm. .
12, noj PAM flocculant, siv cov yas, iav, lossis stainless hlau ntim, siv tsis tau hlau ntim, qhov no yog vim hlau ion yog ua rau tag nrho cov tshuaj polyacrylamide degradation ntawm catalyst, yuav ua rau polyacrylamide tsis ua hauj lwm.Yog li ntawd, nyob rau hauv lub polyacrylamide configuration, hloov lwm lub tsev, cia, sim zam nws thiab hlau hu.
13, PAM flocculant preservation: polyacrylamide nyob rau hauv cia, tsis tuaj yeem raug tshav ntuj, ntub dej, kub kub ci, dej thiab lwm yam.Nws muaj lub neej txee ntawm ob xyoos.
Kaum peb cov ntsiab lus saum toj no yog ib feem ntawm cov lus qhia ua haujlwm uas peb lub tuam txhab cov neeg ua haujlwm tau sib sau ua ke raws li cov neeg siv khoom yav dhau los kev sib tham thiab tawm tswv yim. Tsuas yog los ntawm kev khiav hauj lwm raws li txoj kev raug, polyacrylamide tuaj yeem ua tiav cov txiaj ntsig zoo tshaj plaws thiab nws cov koob tshuaj tuaj yeem yog lub xeev tshaj plaws.Cia siab rau qee tus neeg siv kev sib cuag tshiab pab thiab kev nkag siab!
Nyob rau hauv lub concentrator, kev siv ntawm polyacrylamide feem ntau yog anionic los yog non-ionic hom, txawv concentrator txheej txheem, ib puag ncig thiab lwm yam nyob rau hauv lub cuam tshuam ntawm kev siv cov uas tsis muaj ionic cationic kab cov nyhuv yog zoo dua, qhov no yog qhov yuav tsum tau rau kev soj ntsuam kuaj thiab computer thwmsim. txiav txim siab.
