Mercury tshem tawm cov pa roj carbon monoxide yog cov khoom siv tshwj xeeb tsim los tshem tawm cov mercury ntawm cov pa roj. Nws yog tsim los ntawm siab - zoo activated carbon los ntawm ib tug tshwj xeeb txheej txheem los tsim sulfur -muaj activated carbon. Cov hauv qab no yog cov ncauj lus kom ntxaws qhia txog kev tshem tawm mercury activated carbon:
1, Cov ntsiab lus thiab cov ntsiab lus
Mercury tshem tawm cov pa roj carbon monoxide siv siab -cov txiv maj phaub plhaub columnar activated carbon, txiv maj phaub plhaub particle activated carbon, thiab lwm yam substrates, uas tshwj xeeb yog kho kom muaj ib tug npaum li cas ntawm cov sulfur. Thaum mercury uas muaj roj dhau los ntawm mercury tshem tawm cov pa roj carbon monoxide, mercury reacts chemically nrog sulfur los tsim mercury sulfide (HgS), uas yog tom qab ntawd tsau rau hauv lub pore qauv ntawm cov activated carbon kom purify cov roj.
2, Daim ntawv thov teb
Mercury tshem tawm cov pa roj carbon monoxide yog siv dav hauv kev kho cov pa roj uas muaj cov kab mob phem mercury, xws li cov pa roj carbon monoxide, cov pa roj carbon monoxide, coking gas, thiab coke cub gas. Vim muaj qhov tsis muaj zog, toxicity, thiab corrosiveness ntawm mercury, nrog rau nws nyiam ua rau catalyst lom, mercury tshem tawm activated carbon plays lub luag haujlwm tseem ceeb hauv kev tiv thaiv tus kheej kev nyab xeeb thiab ib puag ncig. Tsis tas li ntawd, nws yog qhov tshwj xeeb tshaj yog tsim nyog rau kev kho mob ntawm cov mercury uas tsis tshua muaj siab uas muaj cov roj cua uas nyuaj rau kev tshem tawm los ntawm lwm txoj hauv kev, kom ntseeg tau tias cov pa hluav taws xob ua raws li cov qauv hauv lub tebchaws lossis cheeb tsam.
3, Main technical indicators, As
Cov kev qhia tseem ceeb ntawm mercury tshem tawm cov pa roj carbon monoxide muaj xws li cov ntsiab lus noo noo, lub zog, ntim ntom ntom, pH tus nqi, dej muaj peev xwm, saturated sulfur peev xwm, thiab particle loj tis. Cov ntsuas no ncaj qha cuam tshuam rau nws cov kev ua haujlwm adsorption thiab kev pabcuam lub neej. Piv txwv li, siab - lub zog thiab siab - qhov ceev mercury tshem tawm cov pa roj carbon monoxide tuaj yeem tiv taus huab cua ntau dua thiab kev hloov pauv siab; Thiab siab saturation sulfur muaj peev xwm txhais tau tias nws muaj peev xwm adsorb ntau mercury ntsiab, yog li ncua nws cov kev pab cuam lub neej.
4, Cov yam ntxwv ntawm lub cev
Mercury tshem tawm cov pa roj carbon monoxide muaj cov qauv tsim pore thiab thaj chaw loj tshwj xeeb, uas yog lub hauv paus rau nws qhov kev ua tau zoo adsorption. Nws cov pores tau muab faib ua peb hom: macropores, mesopores, thiab micropores. Cov pores no sib cuam tshuam los ua ib tsob ntoo zoo li cov qauv, uas yog qhov tsim nyog rau kev nthuav dav thiab adsorption ntawm mercury vapor. Lub caij no, cov pab pawg ua haujlwm nyob rau saum npoo ntawm cov pa roj carbon activated kuj muaj qhov cuam tshuam loj rau nws qhov kev ua haujlwm adsorption.
5, Txoj kev npaj
Muaj ntau txoj hauv kev los npaj cov mercury tshem tawm cov pa roj carbon monoxide, tab sis cov ntsiab lus tseem ceeb zoo sib xws. Feem ntau suav nrog cov kauj ruam xws li kev xaiv raw khoom, crushing thiab tshuaj ntsuam xyuas, carbonization ua kom, thiab kev kho cov tshuaj sulfur. Sulfur loading kev kho mob yog ib qho ntawm cov kauj ruam tseem ceeb, thiab los ntawm kev tswj cov sulfur loading npaum li cas thiab txoj kev, qhov kev ua tau zoo thiab kev siv los ntawm mercury tshem tawm cov pa roj carbon monoxide tuaj yeem ua kom zoo dua.
6, Kev ceev faj rau kev siv
Thaum siv cov mercury tshem tawm cov pa roj carbon monoxide, cov ntsiab lus hauv qab no yuav tsum raug sau tseg: ua ntej, cov qauv tsim nyog thiab cov lus qhia tshwj xeeb yuav tsum raug xaiv raws li qhov tseeb ntawm cov roj muaj pes tsawg leeg thiab kev ua haujlwm muaj peev xwm; Qhov thib ob, kev tshem tawm cov mercury efficiency thiab kev pab cuam lub neej yuav tsum tau sim tsis tu ncua rau kev hloov raws sij hawm; Thaum kawg, yuav tsum tau saib xyuas kom tsis txhob ya raws thiab siab -kub oxidation ntawm cov pa roj carbon activated kom tsis txhob cuam tshuam nws cov adsorption kev ua tau zoo thiab kev pabcuam lub neej.
Hauv cov ntsiab lus, mercury tshem tawm cov pa roj carbon monoxide yog cov khoom siv hluav taws xob zoo thiab ib puag ncig zoo uas tau siv dav thiab ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw. Nrog rau kev nce qib ntawm kev siv thev naus laus zis thiab kev nthuav dav ntawm daim ntawv thov, peb ntseeg tias nws txoj kev lag luam yuav dhau los ua qhov dav dua.
