Hauv kev lim dej, huab cua lim thiab cov txheej txheem kev lag luam, anthracite lim media yog dav siv los ua qhov siab -kev ua tau zoo, ib puag ncig tus phooj ywg pom nruab nrab. Nws lub cev tshwj xeeb- tshuaj lom neeg cov khoom-siab hardness, cov ntsiab lus tsis tshua muaj tshauv thiab muaj peev xwm adsorption muaj zog- ua rau nws yog thawj qhov kev xaiv rau ntau lub lag luam. Txawm li cas los xij, qhov zoo sib txawv heev ntawm kev ua lag luam, yog li paub yuav ua li cas xaiv txoj cai anthracite lim xov xwm yog ib qho kev txhawj xeeb. Tsab ntawv xov xwm no muaj cov lus qhia dav dav hais txog cov yam ntxwv tseem ceeb, cov txheej txheem xaiv tseem ceeb, cov ntawv thov raug mob thiab ceev faj.
Anthracite lim xov xwm yog tsim los ntawm ntuj anthracite thee uas yog crushed, tshuaj ntsuam thiab ntxuav. It is characterized by a fixed-carbon content usually above 90 %, low volatile matter and ash, moderate density and uniform particle size. Cov yam ntxwv no ua rau nws pom kev ua haujlwm zoo thiab ua haujlwm ntev. Cov ntaub ntawv ntxhib saum npoo thiab zoo- tsim cov porosity sab hauv zoo adsorb tshem tawm cov khib nyiab, organic teeb meem, hnyav- hlau ions thiab lwm yam impurities. Muaj zog tshuaj lom neeg ruaj khov, acid / alkali tsis kam thiab tsis tshua muaj kev pheej hmoo ntawm txhaws ua rau nws tsim nyog rau kev siv sijhawm ntev -.
Particle loj ncaj qha cuam tshuam rau kev pom kev ua haujlwm. Qhov ntau yog 0.8-1.2 hli; cov lus qhia meej yuav tsum phim lub lim dej. High uniformity muab ntau ruaj khov efficiency. Txheeb xyuas qhov particle- qhov loj me ntawm kev faib khoom ntawm daim ntawv lo thiab zam cov khoom siv nrog qhov dav, sib xyaw ua ke.
Kev ruaj khov siab dua - cov ntsiab lus carbon txhais tau tias muaj kev huv siab dua thiab muaj zog dua adsorption. Hwm anthracite yuav tsum muaj ntau dua los yog sib npaug rau 90% taag carbon thiab<8 % ash. Excessive ash reduces adsorption performance and may increase back-wash frequency.
Vim tias cov xov xwm raug rov ua dua hydraulic thiab puas, hardness thiab hnav tsis kam yog qhov tseem ceeb. Cov khoom siv tawv tawg yooj yim dua thiab kav ntev dua. Ib qho yooj yim kais sim lossis cov chaw tsim khoom hnav-index daim ntawv qhia tuaj yeem muab qhov kev ntsuas thawj zaug.
Cov ntsiab lus noo noo yuav tsum tsawg li tsawg tau, feem ntau<5 %, to prevent caking during storage or operation. The product must also be thoroughly washed and free of silt or other impurities that could degrade filtrate quality.
Xaiv cov tuam txhab lag luam uas muaj ntawv tso cai tsim khoom raug cai thiab thib peb -cov ntaub ntawv xeem. High -cov khoom siv lim dej zoo anthracite feem ntau tau lees paub rau lub teb chaws lossis cov qauv kev lag luam xws li CJ/T 43-2005.
Raws li kev lag luam thiab kev lim dej zoo, anthracite yuav tsum tau xaiv thiab siv nrog ntau yam hauv siab. Los ntawm kev nkag siab nws cov khoom, paub txog cov txheej txheem xaiv thiab siv nws kom raug, cov neeg siv tuaj yeem siv nws qhov zoo thiab txhim kho tag nrho cov lim dej.
