Chotsitsa cha Desulfurization

II. Madera Atatu Ogwira Ntchito a Desulfurization Absorber

Choyatsira mpweya chimagawidwa m'magawo atatu ogwira ntchito kuyambira pamwamba mpaka pansi: okosijeni crystallization, kuyamwa ndi malo ochotsera.

(1) Malo oyeretsera makristalo amatanthauza dziwe losungunuka la choyamwitsa, ndipo ntchito yake yayikulu ndikusungunula miyala yamchere ndikuwonjezera calcium sulfite.

(2) Malo oyamwitsa amaphatikizapo malo olowera mpweya, thireyi ndi zigawo zingapo za ma spray. Pali ma nozzles ambiri opanda kanthu pa gawo lililonse la chipangizo chopopera; ntchito yayikulu ya ma absorption ndi kuipitsa acid ndi kuyamwa phulusa mu mpweya wotuluka mpweya.

(3) Malo ochotsera mpweya ali ndi ma demister awiri pamwamba pa gawo lopopera. Ntchito yake yayikulu ndikulekanitsa madontho a mpweya wotuluka, kuchepetsa mphamvu ya zida zomwe zili pansi pa madzi ndi kuchuluka kwa zomwe zimayamwa mpweya.

Malo oyamwa a absorber amatanthauza malo omwe ali pakati pa mzere wapakati wa malo olowera a absorber ndi omwe ali pamwamba kwambiri. Dothi lopopera limatsuka mpweya wotuluka womwe uli ndi sulfure m'derali. Kutalika kokwanira kwa malo oyamwa kumatsimikizira kuchuluka kwa desulfurization. Kutalika kwakukulu, kumachepetsa kuchuluka kwa kayendedwe ka mpweya wofunikira. Pansi pa zofunikira zomwezo pa kuchuluka kwa desulfurization.

Malo opopera a absorber amatanthauzidwa motere:

(1) Nsanja yopopera: 1.5m pansi pa nozzle yotsika kwambiri kufika pamalo otulukira nozzle yapamwamba kwambiri.

(2) Nsanja ya mzati wamadzimadzi: kuchokera pamalo otulukira mpweya wochepa kwambiri mpaka 0.5m pamwamba pa mzati wamadzimadzi wapamwamba kwambiri pamene mapampu onse oyendera madzi akuyenda.

Choyamwitsa mpweya ndiye chida chachikulu cha dongosolo lochotsa sulfure ya mpweya wa flue. Chimafuna malo akuluakulu olumikizirana ndi gasi ndi madzi, kuyamwa bwino kwa mpweya, komanso kutayika pang'ono kwa mphamvu. Ndi choyenera kuchiza mpweya wa flue wa flue wa flue. Njira zazikulu zotsatirazi zimamalizidwa mu chipangizochi:

① Kumwa mpweya woipa mu slurry yotsukira;

② Kulekanitsa mpweya wa flue ndi slurry yotsukira;

③ Kuchepetsa kukhuthala kwa matope;

④ Kuyika kwa okosijeni mu gypsum;

⑤ Kupangidwa kwa kristalo ya gypsum.

III. Kapangidwe ka Absorber

Chopopera mpweya nthawi zambiri chimagawidwa m'zipinda ziwiri, cholowera mpweya wa flue ndi chotulutsira mpweya wa flue. Cholowera mpweya wa flue ndi chotulutsira mpweya chimakhala pakati pa chopopera mpweya ndi pamwamba pa chopopera mpweya mofanana. Chopopera mpweya wa flue chingagawidwe m'zipinda ziwiri, chopopera mpweya ndi malo otulutsira mpweya. Dziwe la slurry lili pansi pa chopopera mpweya wa absorber, ndipo chopopera mpweya ndi chopopera mpweya zili pakati pa chopopera mpweya wa flue ndi chotulutsira mpweya. Chopopera mpweya wa flue cha chopopera mpweya chingakhale chotulutsira mpweya chapamwamba kapena chotulutsira cham'mbali chopingasa.

Malo opopera mankhwala achikhalidwe ali ndi zigawo zopopera mankhwala ndi ma nozzle ndi zipangizo zina. Kutengera ndi njira yochotsera sulfure, malo opopera mankhwala a ma absorber ena adzakhalanso ndi ma tray, ndodo za Venturi ndi zipangizo zina.

IV. Zofunikira pa kapangidwe ka Absorber

(1) Chiŵerengero cha calcium-sulfure sichiyenera kupitirira 1.05.

(2) Pogwiritsa ntchito chotsukira mpweya mkati mwa nsanja, liwiro la mpweya wofewa wa chosungunula mpweya pansi pa kapangidwe kake siliyenera kupitirira 3.8m/s, zomwe zingayang'aniridwe ndi Corimafutasfotsikaanakumanaer.

(3) Kapangidwe kogwirizana ka dziwe losambira ndi thupi la nsanja ndi komwe kumakondedwa.

(4) Nthawi yokhalamo ya slurry sayenera kupitirira mphindi 4, ndipo nsanja yamadzimadzi ya mzati iyenera kukhala osachepera mphindi 2.5.

(5) Mzere wosungira madzi ndi chophimba cha mvula ziyenera kuyikidwa pamalo olumikizirana a flue yolowera madzi ndi khoma loyima la flue yolowera madzi.

(6) Cholowera cha nsanja yopanda madzi chiyenera kukonzedwa mopingasa mopingasa. Pamene dongosolo lolowera lopingasa lagwiritsidwa ntchito, ziyenera kutsimikiziridwa kuti malo otsika kwambiri a cholowera cha madzi pa chigongono choyamba pafupi ndi cholowera cha cholowera cha madzi ndi okwera ndi 1.5 mpaka 2m kuposa mulingo wamba wa madzi ogwirira ntchito a dziwe losambira la cholowera cha madzi. Cholowera cha nsanja yamadzi chikhoza kukonzedwa mopingasa kapena moyimirira.

(7) Mtunda pakati pa zigawo zopopera zapafupi za nsanja yopanda chopopera suyenera kukhala wochepera 1.8m.

(8) Gawo lapamwamba la kupopera la nsanja yopanda kanthu liyenera kupopera pansi, ndipo mtunda wa ukonde kuchokera ku gawo lotsika kwambiri la chopoperacho suyenera kupitirira 2m.

(9) Pa nsanja zopopera zokhala ndi mathireyi okhala ndi mabowo ndi ma tabulator, mathireyi okhala ndi mabowo ndi masamba a ma tabulator ayenera kupangidwa ndi zinthu zotsutsana ndi dzimbiri.

(10) Ngati chipangizo chotenthetsera ndi kusinthira kutentha kwa mpweya wotuluka sichinakhazikitsidwe, kusankha magawo a kapangidwe monga kuchuluka kwa madzi otuluka mu nsanja yopanda kanthu, kuchuluka kwa mpweya wamadzimadzi, ndi kuchuluka kwa madzi oundana mu absorber kuyenera kuganizira zofunikira pakugwiritsa ntchito bwino kwa desulfurization ndi mphamvu ya zinthu monga kuchepetsa kuchuluka kwa madontho a mpweya wotuluka mu mpweya.

(11) Kapangidwe ka choyatsira mpweya kayenera kusinthidwa kuti kagwirizane ndi kapangidwe ka boiler ndi kuchuluka kwa sulfure ya malasha.osati nyukiliyaslurry kachulukidwe meterkuchokeraLonnmeterNdikofunikira kuyang'anira kuchuluka kwa miyala yamchere ndi gypsum pamalo otulukira kuti zitsimikizire kuchuluka kokwanira kwa sulfure.
