The NaOH mayamwidwe SO2 odzaza nsanja ndi wamba gasi mayamwidwe zida, amene nthawi zambiri ntchito flue gas desulfurization ndondomeko.Mfundo yake yaikulu ndi kupopera mankhwala NaOH pa waya mauna malata kulongedza katundu, kuyamwa mpweya asidi monga SO2 ndi kuchita ndi NaOH kupanga lolingana mchere, kuti akwaniritse cholinga kuyeretsa chitoliro mpweya.
Chinsanja chodzaza nthawi zambiri chimapangidwa ndi corrugated wire mesh packing wosanjikiza, chogawa chamadzimadzi, cholowera mpweya, potulutsira mpweya, doko lotulutsa madzi, doko lotulutsa ndi magawo ena.The zitsulo mauna malata kulongedza wosanjikiza ndi olimba kulongedza katundu wodzazidwa mu nsanja yodzaza, ndipo ntchito yake ndi kuonjezera kukhudzana dera ndi kuonjezera anachita dzuwa.Wogawira madzi ndi chipangizo chomwe chimapopera njira ya NaOH mofanana pamapaketi a waya.Mpweya wolowetsa mpweya umagwiritsidwa ntchito poyambitsa mpweya wa flue wokhala ndi mpweya wa asidi monga SO2, pamene mpweya umagwiritsidwa ntchito kutulutsa mpweya woyeretsedwa.Kutulutsa kwamadzimadzi kumagwiritsidwa ntchito kutulutsa njira ya NaOH yomwe yatenga SO2, pomwe doko lotulutsa likugwiritsidwa ntchito kutulutsa mpweya woyeretsedwa komanso mpweya wosasinthika.
Mu nsanja yodzaza, yankho la NaOH lidzalumikizana ndi kuyamwa mpweya wa asidi monga SO2 mu gasi wa flue, ndikuchitapo kanthu kuti apange mchere wofanana.Pochita izi, zinthu monga kuchuluka kwa yankho la NaOH, kuchuluka kwa kupopera mbewu mankhwalawa, komanso kutentha kumakhudza kuyamwa bwino.Chifukwa chake, muzogwiritsa ntchito, ndikofunikira kusintha magawo ogwiritsira ntchito nsanja yodzaza malinga ndi zomwe zimafunikira komanso magawo amafuta a flue.
Kuphatikiza apo, nsanja yodzaza imafunikiranso chithandizo chamankhwala kuti zitsimikizire kuti mpweya woyeretsedwa ndi madzi otayidwa ukukumana ndi miyezo yachilengedwe.Nthawi zambiri, yankho la NaOH lidzasonkhanitsidwa mu dziwe lamadzi lapansi, ndipo limatha kutulutsidwa pambuyo poti silinakhazikitsidwe komanso kugwa.
Mwachidule, nsanja yonyamula ya NaOH SO2 ndi chida chofunikira choyeretsera mpweya.Popopera mankhwala NaOH pa corrugated waya mauna kulongedza katundu, SO2 ndi ena acidic mpweya odzipereka ndi anachita ndi NaOH kupanga mchere, kuti akwaniritse cholinga kuyeretsa chitoliro mpweya..Pakugwiritsa ntchito, ndikofunikira kusintha magawo ogwiritsira ntchito nsanja yodzaza malinga ndi zofunikira za ndondomekoyi ndi zigawo za mpweya wa flue, ndikuchita chithandizo chautsi kuti chikwaniritse zofunikira zachitetezo cha chilengedwe.
