Ⅰ. Principle

SO2 ndeimwe yezvinosvibisa mhepo uye chiratidzo chakakosha chekudzora kusvibiswa kwemaindasitiri gasi kusvibiswa muChina. Parizvino, ese machina anopisa marasha emuchina muChina aita mapurojekiti eflue gasi desulfurization, pakati peiyo yakanyanya desulfurization tekinoroji ndeye limestone/gypsum wet flue gas desulfurization (WFGD). Mukuita uku, limestone slurry inoshandiswa seinomwisa, iyo iri mukupesana nekusangana ne flue gasi mu desulfurization tower uye yobva yasanganiswa zvizere. Mushure mekunge iyo SO2 mugesi reflue inopindirana neinomwisa, ikemikari inopindirana nemhepo ine oxidizing inopeperetswa neiyo oxidizing fan kuumba gypsum.

Pane tangi ine slurry pazasi peshongwe yekunyura, uye iyo nyowani yekunyura inoputirwa mu slurry tank kuburikidza ne limestone yekudyisa slurry pombi; pasi pebasa re agitator, inosanganiswa neiyo iripo slurry mu slurry tank; ipapo, slurry inotenderera pombi ichasimudza yakavhenganiswa slurry kune yakapfapfaidza layer uye ipfapfaize pasi kuti ibatane nenyere gasi mukupokana-ikozvino kuyerera. Kuzadzikiswa kwakanaka uye nenguva kweiyo nyowani yekunyudza kwakakosha mukati mese maitiro. Kana huwandu hwekuwedzera husina kukwana, zvakaoma kuvimbisa kushanda kwe desulfurization; kana mari yekuwedzera yakawandisa, inoderedza chiyero chekushandiswa kweiyo inonyudza, uye inokanganisa kunaka kwe desulfurization ne-zvigadzirwa. Naizvozvo, limestone slurry pombi kutonga chikamu chakakosha chekushanda kweFGD.

Ⅱ. Mapombi anodiwa nehurongwa hwekugadzirisa

1. Limestone yekugadzirira system

2. Pombi yeabsorption tower system

3. Flue gas system

4. Pombi yegypsum dewatering system

5. Mapombi ekuburitsa masisitimu

6. Mapombi ekugadzirisa marara emvura

Kunze kweiyo flue gasi system, masisitimu ari pamusoro anozoda slurry pombi. Muiyo absorption tower system, huwandu hwejekiseni hwakakura, saka dhayamita yepombi yakakura. Mapombi ari muchikamu ichi akakura-akakosha pombi akagadzirirwa desulfurization, uye mapombi anoshandiswa mune mamwe masisitimu ndiwo edu anowanzo shandiswa madiki uye epakati-saizi slurry pombi. Zvinoenderana nemamiriro eiyo slurry, zvinhu zvakasarudzwa zvezvikamu zvinoyerera zvese zvinopfeka-resistant uye corrosion-resistant.
