Kuyenda kwa njira yamphero yozungulira yozungulira yopukutiraDongosololi ndi losalala, ndalama zimasungidwa ndipo kasamalidwe ka ntchito ndi kosavuta. Posankha dongosolo la njira zopangira ndi kusankha zida za ufa wa laimu wosungunuka, njira zatsopano zokhwima komanso zodalirika ziyenera kutsatiridwa, zomwe ndizotsika mtengo, zomveka, zothandiza komanso zodalirika.

Zinthu zingapo zazikulu zomwe zimakhudza bwino ntchito ya desulfurization:

1. Mtundu wa miyala ya laimu

Mlingo wa miyala yamchere umatsimikiziridwa ndi kuchuluka kwa CaO. Kuchuluka kwa CaO mu miyala yamchere yoyera ndi 56%. Kuchuluka kwa miyala yamchere, kumakhala bwino kwambiri. Monga wopanga njira, popanga zosakaniza, simuyenera kungowerengera kapangidwe kake ka mankhwala, komanso kumvetsetsa mawonekedwe ake enieni. Kuchuluka kwa calcium oxide mu miyala yamchere yoyambirira ndi 48% - 54%; Miyala yamchere sikutanthauza kuti imafuna kuchuluka kwa CaO. Miyala yamchere yokhala ndi CaO>54% ndi yoyera kwambiri ndipo imasungunuka. Sikophweka kuipera ndipo imakhala ndi kukhazikika kwamphamvu kwa mankhwala, kotero sikoyenera kugwiritsidwa ntchito ngati chotsukira.

2. Kusalala kwa ufa wa laimu

Kapangidwe ka tinthu tating'onoting'ono ta ufa wa miyala yamchere kakakhala kakang'ono, malo enieni a pamwamba pake amakhala akulu. Popeza kuti kusungunuka kwa miyala yamchere kumakhala kofanana ndi madzi olimba, ndipo kuchuluka kwake kumafanana ndi malo enieni a tinthu ta miyala yamchere, tinthu tating'onoting'ono ta miyala yamchere timakhala ndi mphamvu yabwino yosungunuka, kuchuluka kwa mitundu yosiyanasiyana yogwirizana nayo, kuchuluka kwa mphamvu yochotsera sulfurization komanso kugwiritsa ntchito miyala yamchere, koma kukula kwa tinthu ta miyala yamchere kukakhala kochepa, mphamvu yophwanyidwa imachuluka. Kawirikawiri, kuchuluka kwa ufa wa miyala yamchere womwe umadutsa sieve ya 325 mesh (44 microns) ndi 95%.

Nthawi yomweyo, kukula kwa tinthu ta ufa wa miyala yamchere kumagwirizana ndi ubwino wa miyala yamchere. Pofuna kuonetsetsa kuti mphamvu ya desulfurization ndi kuchuluka kwa kugwiritsa ntchito miyala yamchere zikufika pamlingo winawake, pamene kuchuluka kwa zinyalala mu miyala yamchere kuli kwakukulu, miyala yamchere iyenera kuphwanyidwa bwino.

Ukadaulo wokonzekera ufa wa limestone pogwiritsa ntchito mphero yozungulira yozungulira yopukutiradongosolo:

Pa njira ya FGD yogwiritsira ntchito ufa wa limestone ngati desulfurizer, ufa wa limestone uyenera kuchitidwa ndi madzi olimba omwe amasungunuka magawo awiri, ndipo liwiro la reaction limakhala labwino pamalo enieni a tinthu ta limestone. Tinthu ta limestone tikamakula pang'ono, ndiye kuti malo enieniwo amakhala akulu. Tinthu ta limestone timasungunuka bwino, ndipo kuchuluka kwa zochita zosiyanasiyana kumakhala kwakukulu. Komabe, kukula kwa tinthu ta limestone tikakula pang'ono, mphamvu zomwe zimagwiritsidwa ntchito pophwanya zimakhala zapamwamba. Nthawi zambiri, kuchuluka kwa ufa wa limestone womwe umadutsa sieve ya 325 mesh (44 microns) ndi 95%. Nthawi yomweyo, kukula kwa tinthu ta limestone kumakhudzana ndi mtundu wa limestone. Pofuna kuonetsetsa kuti mphamvu ya desulfurization ndi kuchuluka kwa kugwiritsa ntchito limestone zikufika pamlingo winawake, pamene kuchuluka kwa zinthu zodetsedwa mu limestone kuli kwakukulu, limestone iyenera kuphwanyidwa bwino. Ukadaulo wachikhalidwe wa chubu chopukusira umagwiritsidwa ntchito kukonzekera ufa wa limestone, womwe umagwiritsa ntchito mphamvu zambiri, kutulutsa kochepa, kuyenda kovuta, komanso kovuta kuwongolera kusalala ndi kugawa tinthu. Ndi chitukuko cha ukadaulo wopukusira, ukadaulo wopukusira wozungulira umatengedwa. Chifukwa cha mfundo yogwiritsira ntchito zinthu zogayira, mphamvu zomwe zimagwiritsidwa ntchito zimakhala zochepa (20-30% kuposa mphamvu zomwe zimagwiritsidwa ntchito pa mphero ya chubu), kapangidwe ka mankhwala ka chinthucho ndi kokhazikika, kukula kwa tinthu tating'onoting'ono kumakhala kofanana, ndipo kayendedwe kake ndi kosavuta.

Limestone yomwe imalowa mu chomera imatulutsidwa mu hopper ndi galimoto kapena forklift, ndipo limestone imaphwanyidwa pang'onopang'ono. Mabuloko a limestone amatumizidwa ku crusher kudzera mu plate feeder. Kukula kwa tinthu ta chakudya nthawi zambiri kumayendetsedwa pa 400-500mm, ndipo kukula kwa tinthu ta kutulutsa kumayendetsedwa pa pafupifupi 15mm. Limestone yophwanyidwa imatumizidwa mu silo ya limestone kudzera mu zida zotumizira, ndipo pamwamba pa silo pali chosonkhanitsa fumbi chimodzi chochotsera fumbi. Limestone yophwanyidwa imayesedwa ndi kugawidwa ndi choyezera liwiro la lamba pansi pa silo, kenako imaperekedwa ku mphero yozungulira yoyimirira ndi chonyamulira lamba kuti ipere. Chopangidwa chomalizidwa ndi ufa wa limestone wokhala ndi ma meshes 250. Ufa wa limestone pambuyo popera umatengedwa kupita ku nyumba yosungiramo zinthu zomalizidwa kuti zisungidwe. Pamwamba pa nyumba yosungiramo zinthu pali chosonkhanitsa fumbi chimodzi chochotsera fumbi. Zopangidwa zomalizidwa zimatumizidwa ku galimoto ya tanki lalikulu kuti ziperekedwe ndi makina akuluakulu pansi pa nyumba yosungiramo zinthu.

Zotsatira za desulfurizationmphero yozungulira yoyimirira:

Njira yopukutira yaHLMmphero yozungulira yoyimirira imagwiritsa ntchito mfundo yopukutira zinthu, yokhala ndi mphamvu yosinthika yopukutira, phokoso lochepa, mphamvu zochepa, kusweka kochepa, kusinthasintha kwamphamvu kuzinthu, kuyenda kosavuta kwa njira komanso kugwira ntchito bwino kwa dongosolo. Dongosolo lonse limagwiritsidwa ntchito pansi pa kupsinjika koipa komanso kuipitsidwa pang'ono kwa fumbi. Njira yopukutira ya vertical roller mill imakhala ndi grain grading yofanana, kupyapyala kwa zinthu zosinthika (kupyapyala kwa zinthu kumatha kufika ma meshes 600 kapena kuposerapo), ndipo kupyapyala kwa zinthu kumatha kuyezedwa mwachangu ndikukonzedwa.
