Upangiri Wofunikira kwa Electrostatic Precipitators: Kumvetsetsa Magwiridwe Awo, Ubwino, Mitundu, ndi Ntchito Zamakampani

Electrostatic precipitators, omwe amafupikitsidwa ngati ESPs, ndi zida zapamwamba zowongolera kuwononga mpweya zomwe zimachotsa bwino tinthu tating'onoting'ono, monga fumbi ndi tinthu tautsi, kuchokera ku mpweya wotulutsa mafakitale. Kuchita bwino kwawo komanso kudalirika kwawo kwawapangitsa kukhala ofunikira m'mafakitale osiyanasiyana, kuphatikiza kupanga magetsi, kupanga zitsulo, kupanga simenti, ndi zina. Nkhaniyi ikufotokoza momwe ma electrostatic precipitators amagwirira ntchito, maubwino, mitundu, ndi kugwiritsa ntchito.

Mfundo yofunikira pa ma ESPs ndi kukopa kwa electrostatic pakati pa tinthu tating'onoting'ono ndi malo omwe amapangidwa mosagwirizana. Njirayi ingagawidwe mozama mu magawo anayi:

1.Charging: Pamene mpweya wotulutsa mpweya umalowa mu ESP, umadutsa mumtundu wa electrodes (kawirikawiri mawaya akuthwa zitsulo kapena mbale) zomwe zimayendetsedwa ndi magetsi ndi magetsi apamwamba. Izi zimayambitsa ionization ya mpweya wozungulira, kutulutsa mtambo wa ma ion abwino komanso oyipa. Ma ion awa amawombana ndi zinthu zomwe zili mu gasi, zomwe zimapatsa mphamvu yamagetsi ku tinthu tating'onoting'ono.

2.Particle Charging: Tizigawo tochajitsidwa (tsopano timatchedwa ion kapena ion-bound particles) timapanga polarized ndipo timakopeka ndi malo okhala ndi positive kapena negative, kutengera polarity yawo.

3.Kusonkhanitsa: Tinthu tating'onoting'ono timene timatulutsa timasunthira kulowera ndipo timayikidwa pazitsulo zosonkhanitsira (zomwe zimakhala zazikulu, mbale zachitsulo), zomwe zimasungidwa m'munsi koma mosiyana ndi ma electrode otulutsa. Pamene tinthu tating'onoting'ono timawunjikana pa mbale zotolera, timapanga fumbi.

4.Kutsuka: Kuti mupitirize kugwira ntchito bwino, mbale zosonkhanitsa ziyenera kutsukidwa nthawi ndi nthawi kuti muchotse fumbi losanjikizana. Izi zimatheka kudzera njira zosiyanasiyana, kuphatikizapo rapping (kugwedeza mbale kuchotsa fumbi), kupopera madzi, kapena kuphatikiza zonse ziwiri. Fumbi lochotsedwalo limasonkhanitsidwa ndikutayidwa moyenera.

Ubwino wandilectrostaticpolandira

Kuchita Bwino Kwambiri: Ma ESP amatha kukwaniritsa magwiridwe antchito ochotsa tinthu opitilira 99%, kuwapangitsa kukhala oyenera kutsatira malamulo okhwima a chilengedwe.

Kusinthasintha: Amatha kuthana ndi kukula kwake ndi kuchuluka kwa tinthu tating'onoting'ono, kuchokera ku tinthu tating'onoting'ono kupita ku fumbi.

Low Pressure Drop: Mapangidwe a ESPs amachepetsa kukana kwa gasi, kuchepetsa kugwiritsa ntchito mphamvu ndi ndalama zogwiritsira ntchito.

Scalability: Ma ESP amatha kupangidwa kuti agwirizane ndi kuthekera kosiyanasiyana, kuyambira pazantchito zazing'ono mpaka kuyika mafakitale akulu.

Utali wautali: Ndi chisamaliro choyenera, ma ESPs amatha kugwira ntchito kwa zaka zambiri, kupereka njira yotsika mtengo pakapita nthawi.

Mitundu ya Electrostatic Precipitators

Ma ESP amtundu wa Plate: Mtundu wofala kwambiri, wokhala ndi mbale zofananira zokonzedwa molunjika kapena mopingasa monga maelekitirodi osonkhanitsira.

Ma chubu amtundu wa ESPs: Amagwiritsa ntchito machubu achitsulo m'malo mwa mbale monga kutolera maelekitirodi, omwe nthawi zambiri amapezeka m'malo okhala ndi kutentha kwambiri kapena mpweya wowononga.

Ma ESP Onyowa: Phatikizani kupopera madzi kuti zonse ziwonjezeke kusonkhanitsa tinthu ndikuthandizira kuchotsa fumbi, makamaka zothandiza pa tinthu tating'onoting'ono kapena tambirimbiri.

Wet ESPs

Mapulogalamu

Kupanga Mphamvu: Mafakitole opangira malasha amagwiritsa ntchito ma ESPs kuchotsa phulusa la ntchentche ndi nkhungu ya sulfuric acid ku mipweya ya flue.

Kukonza Zitsulo: Mafakitale azitsulo ndi aluminiyamu amadalira ma ESPs kuwongolera mpweya wochokera kung'anjo, zosinthira, ndi mphero.

Kupanga Simenti: Popanga clinker, ma ESP amatenga fumbi ndi zinthu zina zomwe zimapangidwa mu uvuni ndi mphero.

Kutenthetsa Zinyalala: Amagwiritsidwa ntchito kuyeretsa mpweya wochokera ku tauni ndi zowononga zinyalala zoopsa.

Kukonza Chemical: Popanga mankhwala monga sulfuric acid, ESPs amathandiza kusunga mitsinje yaukhondo.

Pomaliza, ma electrostatic precipitators ndi zida zofunika kwambiri zochepetsera kuipitsidwa kwa mpweya m'mafakitale osiyanasiyana. Kuchita bwino kwawo, kusinthasintha, komanso kutsika mtengo kumawapangitsa kukhala chisankho chokonda kuwongolera utsi wotulutsa mpweya komanso kuteteza thanzi la anthu komanso chilengedwe. Pamene ukadaulo ukupita patsogolo, ma ESP akupitilizabe kusinthika, kuphatikiza mapangidwe ndi zida zatsopano kuti zikwaniritse zomwe zikuchulukirachulukira za malamulo a chilengedwe ndi njira zama mafakitale.
