Vim li cas ho ua rau cov pa roj carbon ua haujlwm poob qis

Qhov kev poob qis ntawm kev ua haujlwm adsorption ntawm cov pa roj carbon activated feem ntau tsis yog los ntawm ib qho xwb, tab sis yog los ntawm kev sib xyaw ua ke ntawm ntau yam xws li kev ua qias tuaj ntawm tshuaj lom neeg, kev hnav khaub ncaws, thiab kev tswj cov txheej txheem. Nrog kev siv cov pa roj carbon activated tas li hauv lub voj voog adsorption-desorption-regeneration, nws thaj chaw tshwj xeeb, cov qauv pore, thiab kev ua haujlwm ntawm qhov chaw maj mam hloov pauv, thaum kawg ua rau muaj peev xwm adsorption tsawg dua, tus nqi adsorption, thiab lub zog kho tshuab tsawg dua. Cov yam tseem ceeb ua rau kev ua haujlwm poob qis ntawm cov pa roj carbon activated suav nrog:

1. Kev Ua Kom Tsis Muaj Organic thiab Kev Ua Kom Tsis Muaj Organic

Cov zaub mov uas yaj tau hauv cov hlau ore, cov tshuaj reagents ua haujlwm, cov dej tsis huv, thiab cov pa phem organic maj mam tso rau ntawm cov qhov hws thiab qhov chaw ntawm cov pa roj carbon activated, tsim cov nplai lossis npog cov chaw nquag, thaiv cov qauv microporous, thiab txo qhov chaw tshwj xeeb thiab lub peev xwm adsorption.

2. Cov nyhuv ua ntej kev nyiag khoom

Qee cov ores muaj cov khoom siv carbonaceous ntuj lossis lwm yam minerals uas muaj peev xwm adsorption, uas feem ntau adsorb kub- cyanide complexes, sib tw nrog activated carbon rau adsorption, yog li txo qhov ua tau zoo ntawm kev thauj khoom kub thiab kub rov qab ntawm cov carbon activated.

3. Kev Siv Hluav Taws Xob Thiab Kev Sib Tsoo Cov Khoom Me Me

Thaum lub sijhawm sib xyaw, kev tsa, kev tshuaj ntsuam, kev xa khoom, thiab kev ncig cov txheej txheem, cov khoom me me ntawm cov pa roj carbon activated raug kev sib txhuam, kev sib tsoo, thiab kev txiav tas li, ua rau cov khoom me me hnav, ua rau hmoov zoo dua, thiab txo qis lub zog, thaum kawg ua rau cov pa roj carbon activated poob thiab cov pa roj carbon ntawm lub cev ntws tawm.

4. Cov nyhuv ntxuav kua qaub tsis txaus

Kev ntxuav kua qaub yog ib kauj ruam tseem ceeb hauv kev tshem tawm cov khoom tsis muaj zog. Yog tias qhov concentration ntawm cov kua qaub, lub sijhawm teb, qhov kub, lossis qhov sib piv ntawm cov kua thiab cov khoom khov tsis raug tswj kom zoo, cov khoom tsis muaj zog xws li calcium, magnesium, hlau, tooj liab, thiab silicon yuav tsis raug tshem tawm tag nrho, cuam tshuam rau kev rov ua dua tshiab ntawm cov pa roj carbon activated thiab txo qis kev ua haujlwm ntawm cov pa roj carbon activated.

5. Kev Tswj Xyuas Tsis Zoo ntawm Cov Txheej Txheem Thermal Regeneration

Thaum lub sijhawm rov ua dua tshiab ntawm cov pa roj carbon, yog tias qhov kub thiab txias rov ua dua tshiab, lub sijhawm nyob, kev ua haujlwm, lossis huab cua ntawm lub cub tawg tsis raug tswj kom zoo, cov organic contaminations tsis tuaj yeem lwj thiab tshem tawm tag nrho, qee qhov adsorption channels nyuaj rau rov qab kho, ua rau kev ua haujlwm adsorption ntawm cov pa roj carbon activated poob qis.

6. Kev Kub Ntxhov Thaum Lub Sijhawm Rov Tsim Dua Thiab Txias (Quenching) Cov Txheej Txheem

Tom qab rov ua dua tshiab hauv qhov kub siab, yog tias qhov txias txias sai dhau lossis qhov kub hloov pauv sai dhau, cov pa roj carbon activated yuav tsim kev ntxhov siab thermal loj heev, ua rau muaj kev tawg ntawm cov khoom me me, tawg, thiab hnav, yog li txo cov khoom siv zog thiab ua rau lub neej ua haujlwm luv dua.

Cov Lus Qhia Txog Kev Ua Haujlwm Zoo Tshaj Plaws ntawm Cov Pa roj Carbon Activated

Yuav kom tswj tau qhov kev ua tau zoo tshaj plaws ntawm cov pa roj carbon activated, yuav tsum tsim kom muaj kev saib xyuas kev ua haujlwm ntawm cov pa roj carbon activated thiab kev tswj cov txheej txheem rov ua dua tshiab, tsom mus rau kev ua kom zoo dua cov ntsiab lus tseem ceeb hauv qab no:

1. Saib xyuas qhov kub thiab txias ntawm lub qhov cub rov ua dua tshiab, qhov ua haujlwm tiav, lub sijhawm nyob, thiab huab cua ntawm lub cub tawg kom ntseeg tau tias muaj kev rov ua dua tshiab thermal txaus thiab ruaj khov;

2. Txhim kho cov txheej txheem ntxuav kua qaub kom zoo dua qub kom tshem tawm cov pa phem inorganic thiab txo qhov txhaws;

3. Tswj xyuas qhov txias (quenching) tom qab rov ua dua kom txo tau qhov tawg ntawm cov khoom me me los ntawm kev ntxhov siab thermal;

4. Txhim kho qhov kev tsim cov pa roj carbon uas tau ua kom zoo dua qub, kev tshuaj ntsuam, thiab kev ncig cov kab ke kom txo tau kev hnav thiab kev tsim cov hmoov zoo;

5. Sim cov ntsuas kev ua tau zoo tseem ceeb ntawm cov pa roj carbon uas ua haujlwm xws li tus nqi iodine, tus nqi abrasion, qhov loj me ntawm cov khoom me me, cov ntsiab lus tshauv, thiab kinetics adsorption, thiab kho cov txheej txheem raws sijhawm.

Los ntawm kev ua kom zoo dua qub ntawm cov pickling, thermal regeneration, thiab cov tshuab xa cov pa roj carbon activated, thiab los ntawm kev tswj hwm cov kev ua haujlwm tseem ceeb ntawm lub qhov cub rov ua dua tshiab, cov qauv pore thiab cov haujlwm ntawm cov pa roj carbon activated tuaj yeem rov qab tau zoo, txhim kho nws cov txiaj ntsig adsorption, lub zog kho tshuab, thiab lub neej voj voog. Qhov no tswj kev ua haujlwm adsorption kub ruaj khov, txo cov kev siv cov pa roj carbon activated, thiab txhim kho tus nqi rov qab kub thiab tag nrho cov txiaj ntsig kev lag luam.
