Txhua tus paub tias hlau oxide liab muaj lub peev xwm ua kom muaj zog thiab yog qhov muaj peev xwm heev. Lub tuam txhab hlau oxide liab yuav qhia luv luv tshuaj lom neeg cov tshuaj tiv thaiv ntawm hlau oxide liab thaum nws siv:
Cov hlau oxide liab feem ntau yog hais txog cov neeg sawv cev uas tshem tawm cov leej faj dawb lossis cov leej faj nyob rau hauv roj, cov ntaub ntawv nyoos lossis lwm yam khoom siv; hauv kev tswj hwm thiab kho cov pa phem, nws tsuas yog hais txog cov neeg sawv cev uas tuaj yeem tshem cov leej faj oxides hauv cov pa hauv paus.
1. Lub tshuab nqus hlau oxide ntawm cov hlau oxide liab tuaj yeem pab cov tshuaj tiv thaiv ncaj qha ntawm SO2, ua kom sai ntawm kev tshem tawm ntawm CaCO3, pab kom sai oxidation ntawm CaSO3 rau CaSO4, ntxiv dag zog rau nag lossis daus ntawm CaSO4, txo qhov piv ua kua-roj, txo cov calcium-sulfur piv, thiab txo qhov evaporation ntawm dej. Thaum cov roj flue inlet SO2 concentration nce thiab siab dua tus nqi tsim, PH tus nqi hauv qhov nqus ntau cov tshuaj tiv thaiv tank yuav txo qis, thiab thaum loj dua Ca / S piv, CaCO3 tuaj yeem yaj sai sai tsis tas yuav tsum nthuav kev nqus ntauwd cov tshuaj tiv thaiv tank ntim. Ua kom cov concentration ntawm calcium ions, khaws PH tus nqi ntawm slurry nyob rau hauv ib txwm muaj, thiab muaj qee yam kev cuam tshuam los ntawm pH tus nqi.
2. Txuas ntxiv lub sijhawm khiav ntawm cov nplais ntu hauv cov haujlwm ua haujlwm thiab txo tus naj npawb ntawm cov khoom siv slurry, uas tuaj yeem txo cov nplai ntawm cov cuab yeej, thiab cov nplai txheej ua nyias. Tom qab lub tshuab kaw, nws ntxuav nrog dej, thiab cov teev txheej yog yooj yim kom poob tawm. Kev faib tawm thiab txav cov nplai ntawm desulfurization system, txo qis siltation ntawm cov nplai, thiab ntxiv cov hlau oxide liab tuaj yeem ua lub luag haujlwm hauv nplai thiab corrosion inhibition, txo qhov txhaws, nplai, xeb, thiab xeb ntawm desulfurization nozzle, thiab txo cov qeeb qeeb Lub tshuab ua kom tsis haum, xeb thiab hnav ntawm lub twj tso kua mis thiab lub tshuab hluav taws xob tuaj yeem txo qhov kev saib xyuas thiab hloov ntawm cov khoom seem hauv desulfurization system. Tshaj tawm qhov xaiv ntau ntawm cov khoom siv desulfurization thiab txhim kho txoj kev cia siab ntawm lub system.
