Kunatsiridza Dziviriro Yenzvimbo: Kusunungura Simba reDynamic Exhaust Gasi Desulfurization Systems.
mufananidzo 1Desulfurization Tower
The pedza gasi desulfurization system chinhu chakakosha midziyo inoshandiswa kuderedza sulfur dioxide (SO2) zviri mu flue gas. Yayo kushanda musimboti uye mashandisirwo siyana zvakafara.
Izvi zvinotevera sumo yakadzama yekupedza Gasi Desulfurization system:
1.Kushanda musimboti
Iyo yekushanda musimboti we exhaust gasi desulfurization system inonyanya kukamurwa kuita wet desulfurization uye yakaoma desulfurization:

Wet desulfurization:Wet desulfurization ndeimwe yeanonyanya kushandiswa desulfurization tekinoroji. Mukunyorova kwedesulfurization process, alkaline mhinduro senge limestone slurry kana sodium hydroxide inowanzo shandiswa sezvinwiwa. Kana iyo flue gasi ichipfuura nepakati pe desulfurization tower, inobatwa zvizere nemhute yemvura kana alkaline mhinduro yakapfapfaidzwa kubva pakupfapfaidza layer. Iyo sulfur dioxide iri muflue gasi inotorwa neinomwisa uye inobata kemikari kuita sulfates (senge calcium sulfite kana calcium sulfate). Zvadaro, aya sulfate anogona kugadziridzwa zvakare, senge oxidation, crystallization, nezvimwewo, kugadzira ne-zvigadzirwa zvakaita segypsum.

Dry desulfurization:Dry desulfurization haishandisi mvura kana mhinduro, asi inoshandisa zvinwiwa zvakaoma (zvakadai se activated carbon, calcium oxide, etc.) kuti adsorb sulfur dioxide mu flue gas. Iyi nzira inowanzokodzera kune dzimwe nguva iyo mvura yemukati mu flue gasi yakaderera kana tsvina yemvura inoda kudziviswa.
2.System kuumbwa
Iyo tsvina gasi desulfurization system inowanzo sanganisira zvinotevera zvikamu zvikuru:
Flue gasi system: Iyo inoumbwa neye inlet flue gasi damper gonhi, bypass flue gasi damper gonhi, simbi flue, nezvimwewo, iyo ine basa rekuunza flue gasi rine sulfur dioxide mu desulfurization system.
Absorbent gadziriro yegadziriro (yemvura nzira): Zvakadai selimestone slurry gadziriro yegadziriro, inosanganisira limestone poda silo, vibrating hopper, midziyo yekuyeresa, screw feeder, slurry kugadzirira muchina, nezvimwewo, inoshandiswa kugadzirira inonwisa inodiwa desulfurization.
Desulfurization tower: Iyo desulfurization tower ndiyo yakakosha midziyo ye desulfurization system. Iyo flue gasi inopindirana nemakemikari neinonyudza mushongwe kuti iwane desulfurization athari. Iyo yakanyorova desulfurization tower inowanzo shongedzerwa nepfapfaidzo layer uye yekurongedza layer yekuvandudza desulfurization kunyatsoita.

Gypsum dehydration system (yakanyorova nzira):Kune-zvakagadzirwa zvakadai segypsum inogadzirwa nekunyorova desulfurization, kurapwa kwekupera mvura mumuviri kunodiwa pakushandiswa kunotevera kana kuraswa.
Public engineering system: Kusanganisira nzira yemvura system, yakaderera-voltage simba rekugovera sisitimu uye compressed air system, nezvimwewo, kupa inodiwa mamiriro ekushanda kune desulfurization system.
Inoenderera mberi Flue Gas Emission Monitoring System (CEMS):inoshandiswa kuyera flue gasi parameters yedesulfurization device munguva chaiyo, kupa data yekugadzirisa maitiro ekushanda kwedesulfurization device, kuve nechokwadi chekushanda kwechigadzirwa, uye kupa data yekuongorora kwekushanda kwedesulfurization device.
3.Application Scope
The pedza gasi desulfurization system inoshandiswa zvakanyanya munzvimbo dzakasiyana dzemaindasitiri, kunyanya iwo maindasitiri anoda huwandu hukuru hwemakemikari kuita uye kugadzira gasi reflue rine sulfur dioxide, senge petrochemicals, kucheneswa kwemafuta, simbi, makemikari mafetiraiza, simbi, magetsi, nezvimwewo.
4.Technical Advantages
The pedza gasi desulfurization system ine zvakawanda zvehunyanzvi zvakanakira, zvinosanganisira yakakwirira desulfurization kunyatsoita, flexible operation mode, wide applicable, uye zvakatipoteredza zvine hushamwari by-zvigadzirwa. Pamusoro pezvo, nekuenderera mberi kwehunyanzvi hwekuita tekinoroji, iyo tsvina gasi desulfurization system inogara ichigadziridzwa uye kuvandudzwa kuti ivandudze desulfurization kunyatsoita, kuderedza mari yekushandisa uye kuderedza kukanganiswa kwezvakatipoteredza.
5.Summary
mufananidzo 10 Waste gasi desulfurization midziyo
Muchidimbu, marara gasi desulfurization system yakakosha yekudzivirira kwezvakatipoteredza, iyo yakakosha zvikuru mukuderedza sulfur dioxide zvirimo mumhepo inobuda mumaindasitiri nekuchengetedza nharaunda uye hutano hwevanhu.
