Desulfurization zida zochizira madzi otayika zimatha kugwira ntchito mokhazikika

Pakupanga gasi wa flue desulfurization m'mafakitale otenthetsera mphamvu, chifukwa cha mphamvu ya desulfurization ndi mpweya wa flue, madzi otayira amakhala ndi zinthu zambiri zosasungunuka, monga calcium chloride, fluorine, mercury ions, ayoni a magnesium ndi zitsulo zina zolemera. zinthu.Malasha ndi miyala ya laimu yomwe imagwiritsidwa ntchito m'mafakitale opangira magetsi atha kuwononga kwambiri madzi oipa.Pakali pano, m'kati kutengera flue gasi desulfurization zipangizo zina matenthedwe mphamvu zomera m'dziko langa, ndi madzi oipa kwaiye muli zambiri inaimitsidwa zolimba ndi zinthu zosiyanasiyana heavy metal, ndicho flue mpweya desulfurization madzi oipa.

Ubwino wamadzi onyansa a desulfurization ndi wosiyana ndi madzi otayira m'mafakitale ena, ndipo ali ndi mawonekedwe a turbidity, mchere wambiri, corrosiveness wamphamvu komanso makulitsidwe osavuta.Chifukwa cha zofunikira za ndondomeko zoteteza chilengedwe, madzi onyansa a desulfurization ayenera kutulutsa zero.Komabe, matekinoloje achikhalidwe amtundu wa zero-emission monga MVR ndi MED ali ndi kuipa kwa ndalama zambiri komanso ndalama zoyendetsera ntchito, ndipo sangathe kugwiritsidwa ntchito kwambiri.Momwe mungakwaniritsire "mtengo wotsika komanso zotulutsa ziro" zamadzi onyansa a desulfurization lakhala vuto lachangu lomwe liyenera kuthetsedwa.

The desulfurization zipangizo zochizira madzi onyansa zimatha kuyika pang'onopang'ono madzi otayika a desulfurization ndi matekinoloje olekanitsa a membrane monga Wastout, R-MF pretreatment, HT-NF kupatukana, ndi HRLE malire kulekana.Ukadaulo wapadera wolekanitsa wa membrane umatengera njira yolowera m'madzi yotalikirapo, mawonekedwe amphamvu kwambiri komanso zinthu zapadera za membrane zomwe zimakhala ndi mphamvu zotsutsana ndi kuipitsidwa, zomwe zimatsimikizira kugwira ntchito kwa nthawi yayitali.Kukonzekera kwadongosolo kumapangitsa kuti zikhale zovuta kupanga polarized wosanjikiza pamwamba pa nembanemba, ndipo ali ndi mphamvu zotsutsana ndi kuipitsa.Mtengo wogwiritsira ntchito dongosololi ndi wotsika, ndipo mtengo wogwiritsira ntchito tani imodzi yamadzi ndi 40-60% yokha ya ndondomeko yachikhalidwe.

Kwa nthawi yayitali, njira yamadzi otayira ya desulfurization yanyalanyazidwa ndi opareshoni chifukwa si gawo la core desulfurization system.Kapena sankhani njira yosavuta yochotsera madzi owonongeka a desulfurization pakumanga, kapena kungosiya dongosolo.Pogwira ntchito, mafakitale opangira magetsi otenthetsera amayenera kumveketsa bwino cholinga ndi zofunikira za chithokomiro cha gasi desulfurization yamadzi onyansa, kugwiritsa ntchito mwanzeru ukadaulo, kupanga dongosolo loyang'anira bwino, kuwongolera bwino mphamvu zowongolera, kulimbitsa ntchito yoyang'anira, ndikuwongolera zotsatira zasayansi ndiukadaulo. kufufuza ndi kugwiritsa ntchito.
