Heavy Hlau Capturing Agent

EXN-904 yog cov organic sulfur hnyav hlau tshem tawm tus neeg sawv cev tsim rau desulfurization system dej khib nyiab; EXN-904 tuaj yeem siv rau hauv chav tsev kub nrog Cu2+, Mn2+, Ni2+, Pb2+, Cd2+, Ag+, Zn2+, Cr3+, Hg2+, thiab lwm yam hauv cov dej khib nyiab Ntau yam ntawm cov hlau hnyav ions reactin sai sai rau cov dej khib nyiab thiab cov dej khib nyiab. los ntawm kev ntxiv cov coagulant (xws li polyaluminum ferric sulfate, polyaluminum chloride, thiab lwm yam), flocculant (xws li anionic polyacrylamide) kom ceev Deposition kom ua tiav qhov kev tshem tawm ntawm cov hlau hnyav ions thiab tag nrho cov kev lag luam uas hnyav hlau muaj kuab paug tuaj yeem kho nrog hnyav hlau tshem tawm tus neeg sawv cev EXN-904, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob. incineration kev kho mob, fais fab nroj tsuag flue gas scrubbing thiab lwm yam dej khib nyiab.

Raws li kev tshawb fawb thiab kev xyaum, EXN-904 muaj peb qhov zoo: 1) toxicity tsawg; 2) Cov nyhuv tshem tawm ntawm cov hlau hnyav ions yog qhov zoo heev, tuaj yeem tshem tawm tag nrho cov hlau hnyav hauv cov hlau ions thiab cov complexes thiab chelates, nyob rau hauv ntau yam tuaj yeem siv ncaj qha rau hauv PH ntau yam . 3) Kev tsim cov insoluble macromolecular peb-dimensional chelates, nyob rau hauv qhov kub thiab txias los yog muaj zog dej ntws, cov khoom siv sulfidation yog qhov yooj yim thiab ruaj khov.

Kev siv tshuaj tshwj xeeb yuav tsum tau txiav txim siab raws li cov txiaj ntsig ntawm kev sim ntsuas dej khib nyiab.

pH ntawm cov dej yuav tsum siab tshaj 2, thiab nws yog pom zoo kom kho nyob rau hauv PH 6-9;

EXN-904 tuaj yeem muab ntxiv ncaj qha lossis diluted;

Qhov dav dav npaum li cas yog 10-100ppm, kev siv tshwj xeeb yog txiav txim siab los ntawm kev sim raws li cov dej zoo; lub sij hawm tshuaj tiv thaiv feem ntau yog li 30min;

Ntxiv inorganic coagulant (xws li polyferric sulfate, polyaluminum chloride) txog 0.05kg-0.2kg / m3 cov dej khib nyiab (uas tuaj yeem raug tshem tawm raws li qhov xwm txheej), lub sijhawm tshuaj tiv thaiv yog li 2min-5min;

Ntxiv 0.1% ntawm anionic polyacrylamide (molecular hnyav li ntawm 8 lab) 1.0ml / L khib nyiab, sai do rau 2 min (kev lag luam khoom noj ntau npaum 0.0005kg-0.002kg / m3 khib nyiab), lub sij hawm tshuaj tiv thaiv yog li 2min-5min, static Settling

Ntsuam xyuas cov dej tsis zoo thiab txiav txim siab txog qhov tsim nyog npaum li cas.

Nquag Hauv 25kg net Yas Nruas, IBC nruas kuj siv tau raws li qhov yuav tsum tau ua.Storage rau 12 lub hlis hauv chav shady thiab qhuav qhov chaw.

Tsis muaj zog alkaline, Tsis txhob sib cuag nrog lub qhov muag thiab tawv nqaij, ib zaug tiv tauj, yaug nrog dej.

Kev sib cuam tshuam ntawm cov hlau hnyav chelating cov neeg ua haujlwm thiab cov hlau hnyav yog raws li hauv qab no: cov hlau hnyav chelating cov neeg ua haujlwm ua haujlwm nrog cov hlau hnyav hnyav ions los ua cov hlau hnyav hnyav, uas yog tom qab ntawd tshem tawm ntawm cov dej khib nyiab los ntawm sedimentation thiab flotation (piv txwv li, yaj huab cua flotation). Cov neeg ua hauj lwm tam sim no muaj xws li: alkaline tshuaj, sulfiding agents, polymeric hnyav hlau chelators, surfactants, adsorbents, thiab bioflocculants.
