Semi-yakaoma fluegasi desulfurizationtekinoroji ndeye flue gasi desulfurization tekinoroji yemaboilers ane huwandu hwe35T/H ~ 670T/H, uye iyo desulfurization inoshanda inogona kusvika kupfuura 85%.
Kupfapfaidza kuomesa chinhu chitsva cheFGD tekinoroji. Kuenzaniswa nemaitiro ekunyorova, mari yaro yekutanga yakaderera, asi huwandu hwe desulfurizer yakakura, saka inowanzoshandiswa mumalahle epakati uye pasi sarufa (
The spray dryingdesulfurization tekinorojiinoshandisa musimboti wekupfapfaidza kuomeswa kuzadzisa chinangwa cheflue gasi desulfurization . The spray drying desulfurization process yakakamurwa kuita 5 nhanho: (1) inonwisa kugadzirira; (2) kunyura slurry atomization; (3) kubata uye kusanganiswa kwemadonhwe emhute uye gasi reflue; (4) evaporation-sarufa dioksijeni kutorwa; (5) kubviswa kwemarara, uye matanho matatu 2, 3 uye 4 ese anoitwa mushongwe yekupfapfaidza yekupfapfaidza.
Kana iyo atomized slurry ikasangana neflue gasi mushongwe yekunyura, iyo inonyudza inotanga kubuda, iyo flue gasi inotonhodzwa uye kunyoroveswa, uye lime slurry inopindirana neSO2 kugadzira chigadzirwa chakaoma chehupfu. Mhedzisiro yese yakakamurwa kuva: SO2 inobatwa nemadonhwe kuti iite calcium sulfite, iyo inopenya mushure mekusvika pakuzara; CaSO3 muchikamu chemhinduro inopindirana neokisijeni yakanyungudika mumadonhwe kuti iite oxidize mucalcium sulfate, iyo inopenya kunze. Sezvo iyo yakanyungudutswa calcium hydroxide inopedzwa panguva ye desulfurization process, yakawanda calcium hydroxide solids inonyungudika zvakare kuti ichengetedze sulfur dioxide yekubvisa reaction kuenda.
Zvinoreva kuomeswa kwemvura kwemadonhwe uye kutonhora uye kunyorovesa maitiro eflue gasi. Kuomeswa kwemadonhwe kwakakamurwa kuita nhanho mbiri: nhanho yekutanga ndeyekubuda kwemahara kwemvura pamusoro pemadonhwe nekuti iyo yakasimba yemukati mumadonhwe ane slurry haina kukura, uye kukurumidza kwekubuda kwemvura kunokurumidza uye kusingachinji. Sezvo mvura inoputika, zvinyoro zvinyorwa zvemadonhwe zvinowedzera, uye danho rechipiri rinoitika apo mashizha anokosha anoonekwa pamusoro pemadonhwe. Sezvo iyo evaporation pamusoro penzvimbo inova diki, hunyoro hunofanirwa kupararira kunze kubva mukati mechikamu kuburikidza nechinhu chakasimba, chiyero chekuomeswa chinoderera, tembiricha yedonhwe rinowedzera uye rinosvika tembiricha yeflue gasi, uye pakupedzisira inoparadzana kubva kune flue. gasi nekuda kwekubuda kwemvura irimo kuti iite zvimedu zvakasimba .
Nguva inotora kuti madonhwe aome kubva pakutanga kwekubuda kwemhepo inokosha zvikuru kune zvose kugadzirwa kwemunyu uye chiyero che desulfurization. Zvinhu zvinokanganisa nguva yekudonha kwedonhwe saizi yedonhwe, madonhwe emvura yemukati, uye tembiricha kukosha kune adiabatic saturation.
Nguva yekutumira: Aug-15-2022
