Kev ntsuas kev kho mob
Ua ntej, cov sulfur yog crushed rau hauv cov hmoov, thiab xa mus rau hauv lub combustion rauv nrog compressed cua rau combustion ntawm 600 ~ 800 ℃. Cov huab cua ntxiv yog kwv yees li 2 npaug ntawm qhov theoretical npaum li cas, thiab qhov concentration ntawm cov pa SO2 yog 10-13.
Thib ob, tom qab txias, tshem tawm plua plav thiab pom, sublimated sulfur thiab lwm yam impurities raug tshem tawm, thiab cov roj kub tau txo mus txog 0 ℃, thiab nws tau dhau mus rau hauv lub reactor series.
Qhov thib peb theem reactor yog maj mam ntxiv nrog niam cawv thiab dej qab zib soda tov rau neutralization cov tshuaj tiv thaiv, cov tshuaj tiv thaiv mis yog raws li nram no:
2NaHSO4 + Na2CO3 - 2Na2SO4 + CO2 + H2O
Qhov tshwm sim ntawm sodium sulfite raug tshem tawm yog ua tiav dhau los ntawm theem ob thiab thawj theem reactor rau kev nqus cov tshuaj tiv thaiv nrog SO2 los tsim cov crystallization ntawm sodium metabisulfite.
