Musystem yekubvisa chloride gas ye limestone-gypsum wet flue, kuchengetedza mhando ye slurry kwakakosha pakushanda kwakachengeteka uye kwakasimba kwesystem yese. Izvi zvinokanganisa zvakananga hupenyu hwemidziyo, kushanda zvakanaka kwe desulfurization, uye mhando yezvigadzirwa. Mazhinji magwenya emagetsi haafariri kushanda kwema chloride ions mu slurry pasystem yeFGD. Pazasi pane njodzi dzema chloride ions akawandisa, manyuko awo, uye matanho ekuvandudza anokurudzirwa.
I. Njodzi dzeChloride Ions Yakawandisa
1. Kukurumidza Kuora kweZvikamu zveSimbi muAbsorber
- Maion echloride anoparadza simbi isingatsvi, zvichipwanya chikamu chepasi.
- Kuwanda kweCl⁻ kunoderedza pH yetsvina, zvichikonzera ngura yesimbi, ngura yakatsemuka, uye ngura yestress. Izvi zvinokuvadza michina yakaita semapombi etsvina uye maagitator, zvichipfupisa hupenyu hwazvo zvakanyanya.
- Panguva yekugadzira ma "absorber", huwandu hweCl⁻ inobvumirwa ndiyo pfungwa huru. Kushivirira kwakanyanya kwechloride kunoda zvinhu zviri nani, zvichiwedzera mitengo. Kazhinji, zvinhu zvakaita se2205 stainless steel zvinogona kubata huwandu hweCl⁻ hunosvika 20,000 mg/L. Kune huwandu hwakawanda, zvinhu zvakasimba zvakaita seHastelloy kana nickel-based alloys zvinokurudzirwa.
2. Kuderedzwa kwekushandiswa kweSlurry uye Kuwedzera kweReagent/Simba rekushandisa
- Ma chloride anowanzo kuwanikwa se calcium chloride mu slurry. Kuwanda kwema calcium ion, nekuda kwemaitiro akafanana ema ion, kunoderedza kunyungudika kwe limestone, kuderedza alkalinity uye kukanganisa maitiro ekubvisa SO₂.
- Maion echloride anokanganisawo kunyudzwa kweSO₂ mumuviri nemakemikari, zvichideredza kushanda zvakanaka kwekubvisa sulfurization.
- Cl⁻ yakawandisa inogona kukonzera kuumbwa kwemabubbles mu absorber, zvichikonzera kuzara, kuverenga kwemvura yenhema, uye kuvhuvhuta kwepombi. Izvi zvinogona kutokonzera kuti slurry ipinde mu flue gas duct.
- Kuwanda kwechloride kunogonawo kukonzera kusanganiswa kwakasimba kwesimbi dzakadai seAl, Fe, uye Zn, zvichideredza mashandiro eCaCO₃ uye pakupedzisira zvichideredza kushanda zvakanaka kwekushandisa slurry.
3. Kuora kweHunhu hweGypsum
- Kuwanda kweCl⁻ mutsvina kunodzivirira SO₂ kunyungudika, zvichikonzera kuwanda kweCaCO₃ mugypsum uye hunhu husina kunaka hwekubvisa mvura.
- Kuti pagadzirwe gypsum yemhando yepamusoro, mvura yekuwachisa yakawedzerwa inodiwa, zvichiita kuti pave nekutenderera kwakashata uye kuwedzera huwandu hwechloride mumvura yakasviba, zvichiita kuti kurapwa kwayo kuve kwakaoma.
II. Manyuko eChloride Ions muAbsorber Slurry
1. Zvishandiso zveFGD, Mvura yeMakeup, uye Marasha
- Machloride anopinda musystem kuburikidza neaya ma inputs.
2. Kushandisa Cooling Tower Blowdown seProcess Water
- Mvura inopfurwa inowanzova ne550 mg/L yeCl⁻, zvichikonzera kuunganidzwa kweCl⁻.
3. Kushanda Zvisina Kunaka kweElectrostatic Precipitator
- Dumbu reguruva rakawanda rinopinda mu absorber rinotakura ma chloride, ayo anonyunguduka mu slurry uye anoungana.
4. Kusakwana Kwemvura Yakasviba
- Kukundikana kuburitsa mvura yakasviba yekubvisa sulfurization zvichienderana nekugadzirwa kwayo uye zvinodiwa pakushanda kwayo kunotungamira mukuunganidzwa kweCl⁻.
III. Matanho Ekudzora Chloride Ions MuAbsorber Slurry
Nzira inoshanda zvikuru yekudzora Cl⁻ yakawandisa ndeyekuwedzera kuburitswa kwemvura yakasviba ye desulfurization uku uchiita shuwa kuti mitemo yekubuditsa mvura yakwana. Mamwe matanho anokurudzirwa anosanganisira:
1. Shandisai Mvura Inopfapfaidza
- Regedza nguva yekutenderera kwemvura mufirita uye dzora kupinda kwemvura inotonhorera kana mvura yemvura mu slurry system kuti mvura irambe yakaenzana.
2. Deredza Mvura Yekuwachisa yeGypsum
- Deredza huwandu hweCl⁻ yegypsum kusvika padanho rakakodzera. Wedzera kubviswa kweCl⁻ panguva yekudiridza nekutsiva slurry ne gypsum slurry itsva kana huwandu hweCl⁻ hwapfuura 10,000 mg/L. Tarisa huwandu hweCl⁻ yeslurry uchishandisamita yekuwanda kwemukatiuye gadzirisa mwero wekubuda kwemvura yakasviba zvinoenderana.
3. Simbisa Kutarisa Chloride
- Nguva nenguva edza huwandu hwe slurry chloride uye gadzirisa mashandiro zvichienderana nehuwandu hwe coal salfur, kuenderana kwezvinhu, uye zvinodiwa nesystem.
4. Kudzora Kuwanda kweSlurry uye pH
- Chengetedza huwandu hweslurry huri pakati pe1080–1150 kg/m³ uye pH iri pakati pe5.4–5.8. Nguva nenguva deredza pH kuti uvandudze mashandiro ari mukati meabsorber.
5. Iva nechokwadi chekuti Electrostatic Precipitators Inoshanda Zvakanaka
- Dzivisa zvidimbu zveguruva zvine huwandu hwakawanda hwechloride kuti zvisapinde mu absorber, iyo yaizonyunguduka youngana mu slurry.
Mhedziso
Maion echloride akawandisa anoratidza kusakwana kwekubuda kwemvura yakasviba, zvichikonzera kudzikira kwekushanda kwe desulfurization uye kusaenzana kwesystem. Kudzora chloride zvinobudirira kunogona kuwedzera kugadzikana kwesystem uye kushanda kwayo. Kune mhinduro dzakagadzirwa kana kuedzaLonnmeterZvigadzirwa zve's zvine rutsigiro rwehunyanzvi rwekugadzirisa matambudziko ari kure, taura nesu kuti uwane mazano emahara pamusoro pemhinduro dzekuyera huwandu hweslurry.
