Kunyowa kwa mafuta onyowa ndi mandimu / miyala yamiyala

Mawonekedwe

• Makina okwanira pamwamba 99% amatha kukwaniritsidwa
• Kupezeka kwa oposa 98% kungakwaniritsidwe
• Engineeringle samadalira malo aliwonse
• Malonda ogulitsa
• Gawo lopanda malire
• Njira yokhala ndi chiwerengero chachikulu kwambiri cha maumboni padziko lapansi

Njira

Njira zofunikira kwambiri za njira yonyowa iyi ndi:

• Kukonzekera ndi Kupanga
• Kuchotsa Sox (HCL, HF)
• Kuthiridwa ndi kuwongolera malonda

Mwanjira imeneyi, miyala yamiyala (CACO3) kapena Quifime (Cao) imatha kugwiritsidwa ntchito ngati njira yoyamwa. Kusankhidwa kwa zowonjezera zomwe zingawonjezedwe kouma kapena ngati kutsuka kumapangidwa pamaziko a ma polojekiti. Kuchotsa sulufule oxides (sox) ndi ena a acid acidic (hcl, HF), mpweya wa flue umayambitsidwa kwambiri ndi wolumala wokhala ndi zowonjezera mu mayamwidwe. Mwanjira imeneyi, malo akulu kwambiri amapezeka kuti azisamutsa misa. M'malo oyamwa, ochokera ku mafuta a flue amakhudzidwa ndi kuyamwa kuti apange calcium sulphium sulphite (Caso3).

Mwala wambiri womwe uli ndi calcium sulphium sulphkate amasonkhanitsidwa mu cholembera dzuwa limp. Miyala yamiyala yomwe imagwiritsidwa ntchito poyeretsa mpweya wowoneka bwino imawonjezeredwa mosalekeza kwa wotyfber sump awonetsetse kuti mphamvu yoyeretsa imakhalabe yokhazikika. Kenako slurry imalowetsedwa mu mayamwidwe.

Mwa kuwomba mpweya kulowa mu chiwombacho, gypsum chimapangidwa kuchokera ku calcium sulphfute ndipo chimachotsedwa mu njirayo ngati gawo la slurry. Kutengera ndi zofunikira pazinthu zomaliza, kutsatsanso chithandizo china kumachitika kuti apange gypsum.

Zomera zamagetsi

Mu Depulpuuriation ya mafuta, otayika otumphuka otalika afalikira omwe agawidwa m'magawo awiri akuluakulu. Awa ndi malo otsekera omwe amapezeka pa mpweya wa flue ndipo amalamphuka, pomwe miyala yamiyala yamizidwa ndikusonkhanitsidwa. Pofuna kupewa madiponsi mu kamp ya dzuwa, slurry imayimitsidwa pogwiritsa ntchito njira zosakanikirana.

Mafuta a flue amayenda pamwamba pamlingo wamadzimadzi kenako kudzera mu mayamwidwe, omwe amatenga milingo yopukutira ndi ma edinator.

Mwala wamwala woyamwa kuchokera ku mpiru woyatsidwa bwino umakhala ndi pakati pa nthawi yomwe pano ndi yotsutsana naye pakali pano. Makonzedwe a Nthambi mu nsanja yopatula ndikofunikira pakuchotsa njira yopezerera. Kukonzekera kochepa kumafunikira kwambiri. Mu Hon Hatanator, madontho amatenga kuchokera ku mayamwidwe ndi mpweya wa flulue amabwezedwanso. Pakukonzeka kutulutsa, gasi yoyera imadzaza ndipo imatha kuchotsedwa mwachindunji kudzera pa nsanja yozizira kapena yonyowa. Kusankha mpweya woyenga koyera kumatha kudzola ndikusunthira ku stack youma.

Kusuta kuchotsedwa kwa kuyamwa kwatuluke komwe kumapezeka koyambirira kudzera pa njira ya hydrocycolones. Nthawi zambiri malo otsekerera omwe kale anali amawonongeka kudzera mu kusefa. Madziwo, omwe amapezeka pamtunduwu, amatha kubwezeretsedwanso. Gawo laling'ono limachotsedwa mu mawonekedwe ozungulira mu mawonekedwe a madzi otayika.

Kasuli wagesi wa mpweya mu mafakitale, zomera zakutha mphamvu kapena zinyalala zakuthambo zimadalira kwambiri kuti pakhale nthawi yayitali komanso yopirira kwambiri zachilengedwe. Ndi mawebusayiti ake, lechler amapereka njira zothetsera utsi ndi zowonjezera zopukutira komanso njira zina mu Defelfuurisation (FGD).
