Kuchotsa sulfure dioxide ku gasi wa flue mwa kuyanika kupopera, kugwiritsa ntchito ukadaulo wowumitsa wa sulphurization poteteza chilengedwe, kugwiritsa ntchito bwino komanso kugwiritsa ntchito ufa wambiri wa sulphates.

Kuchotsa sulfure dioxide ku gasi wa flue mwa kuyanika kupopera, kugwiritsa ntchito ukadaulo wowumitsa wa sulphurization poteteza chilengedwe, kugwiritsa ntchito bwino komanso kugwiritsa ntchito ufa wambiri wa sulphates.

Chidule:

Chofunikira chofunikira pakufalikira kwaukadaulo waukadaulo wa sulfure wowumitsidwa ndi chingamu ndikuti zitha kuthana ndi vuto la chitukuko chanzeru komanso kugwiritsa ntchito kuchuluka kwa ufa wa sulphate mutatha kuyanika. Itha kupangidwanso ngati choyamwitsa, gawo la zinthu zowuma zitha kubwezeretsedwanso, monga zowonjezera zapadziko lapansi, zimasandulika phala lomwe limagwiritsidwa ntchito pochotsa simenti, lopangidwa ndi miyala ya granular yokumba ...

Pamene mphamvu ya dziko ikuwonjezeka chaka ndi chaka, kuyaka ndi kugwiritsiridwa ntchito kwa malasha monga gwero loyamba la mphamvu, kutulutsa sulfure wochuluka wa sulfure komanso kupanga mvula ya acidic m'madera, kwachititsa kuti chilengedwe chiwonongeke kwambiri, chomwe chimasokoneza chilengedwe, ndikuwononga nkhalango, acidification ya dothi ndi nyanja, ndi kuwonongeka kwa nyumba.

Choncho, kulamulira ndi kuchepetsa kutuluka kwa sulfure dioxide ndi ntchito yofunikira. Pakati pa matekinoloje ambiri a desulfurization, kugwiritsa ntchito njira yowumitsa kutsitsi kuchotsa sulfure dioxide ku mpweya wa flue ndi teknoloji yomwe ikukula kwambiri. Tekinoloje iyi idaphunziridwa koyamba m'ma 1970 ndipo idayikidwa muzamalonda kumapeto kwa zaka za m'ma 1970. Iwo ali zochepa ndalama, ntchito yosavuta, mkulu sulfure kuchotsa dzuwa, palibe kuipitsa yachiwiri, ndipo poyerekeza ndi njira yonyowa ntchito yochuluka mu flue mpweya desulfurization, mankhwala ufa opangidwa ndi kutsitsi kuyanika njira desulfurization ndi kusankha kwambiri ndi phindu chitukuko.

Utsi wowumitsa gel osakaniza sulfure luso chimagwiritsidwa ntchito chofunika chofunika ndi ngati angathe kuthetsa wololera chitukuko ndi magwiritsidwe ambiri a ufa sulphate pambuyo kuyanika. Ikhoza kusinthidwanso ngati choyamwitsa, gawo la zinthu zowuma likhoza kubwezeretsedwanso, monga chowonjezera cha dziko lapansi, losandulika phala la simenti losasunthika, lopangidwa ndi mchenga wonyezimira wopangidwa ndi granular ndi miyala, monga chodzaza ndi zomangira m'malo mwa konkire yomwe imagwiritsidwa ntchito kawirikawiri ndi phula ndi zina zotero.
