Kodi Electrostatic Precipitator Ndi Chiyani?

Makampani ndi mbali yofunika kwambiri ya dongosolo lathu lazachuma, ndipo ambiri amakhulupirira kuti ndi ufulu wawo kupirira zofukiza za fakitale zomwe zimatsamwitsa mpweya. Koma si ambiri akudziwa kuti teknoloji ili ndi njira yabwino yothetsera izi kwa zaka zopitirira zana mu mawonekedwe a electrostatic precipitators. Izi zimachepetsa kwambiri kuipitsa komanso zimathandiza kukonza chilengedwe.

Kodi Electrostatic Precipitator Ndi Chiyani?

Electrostatic precipitator (ESP) imatanthauzidwa ngati chipangizo chosefera chomwe chimagwiritsidwa ntchito kuchotsa tinthu tating'ono tomwe timakhala ngati utsi ndi fumbi la mpweya wabwino. Ndi chipangizo chomwe chimagwiritsidwa ntchito kwambiri poletsa kuwononga mpweya. Amagwiritsidwa ntchito m'mafakitale monga zitsulo zachitsulo, ndi zomera zamagetsi zamagetsi.

Mu 1907, pulofesa wa chemistry, Frederick Gardner Cottrell, adapereka chilolezo choyamba cha electrostatic precipitator yomwe imagwiritsidwa ntchito kusonkhanitsa nkhungu ya sulfuric acid ndi utsi wa lead oxide wotuluka kuchokera kuzinthu zosiyanasiyana zopanga ndi kusungunula asidi.

Mfundo Yogwira Ntchito ya Electrostatic Precipitator

Mfundo yogwira ntchito ya electrostatic precipitator ndiyosavuta. Amakhala ndi ma elekitirodi awiri: zabwino ndi zoipa. Ma elekitirodi olakwika ali ngati mawaya, ndipo ma elekitirodi abwino ndi mbale. Ma electrode awa amayikidwa molunjika ndipo amasinthasintha.

ntchito mfundo ya electrostatic precipitator

Tinthu tating'onoting'ono tomwe timakhala ndi mpweya monga phulusa timayatsidwa ndi ma elekitirodi otulutsa mphamvu kwambiri ndi corona effect. Tinthu tating'ono ting'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono timakhala tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono.

Malo olakwika amagetsi apamwamba a DC amagwiritsidwa ntchito kulumikiza ma electrode olakwika, ndipo malo abwino a DC gwero amagwiritsidwa ntchito kulumikiza mbale zabwino. Kuti muyanitse sing'anga pakati pa zoyipa ndi ma elekitirodi abwino, mtunda wina umasungidwa pakati pa ma elekitirodi abwino, oyipa ndi magwero a DC zomwe zimapangitsa kuti magetsi azikwera kwambiri.

Sing'anga yomwe imagwiritsidwa ntchito pakati pa maelekitirodi awiriwa ndi mpweya. Pakhoza kukhala kutulutsa kwa corona kuzungulira ndodo za ma elekitirodi kapena mawaya a waya chifukwa cha kuipitsidwa kwakukulu kwa milandu yolakwika. Dongosolo lonse limatsekeredwa mu chidebe chachitsulo chokhala ndi cholowera cha mpweya wa flue ndi potulutsiramo mpweya wosefedwa. Pali ma elekitironi ambiri aulere monga ma elekitirodi amapangidwa ndi ionized, omwe amalumikizana ndi tinthu tating'ono ta gasi, zomwe zimawapangitsa kukhala olakwika. Tinthu tating'onoting'ono timapita ku maelekitirodi abwino ndikugwa chifukwa champhamvu yokoka. Mpweya wa chitoliro umakhala wopanda fumbi ngati umayenda kudzera pamagetsi a electrostatic ndipo umatulutsidwa kupita kumlengalenga kudzera mu chumuni.

Mitundu ya Electrostatic Precipitator

Pali mitundu yosiyanasiyana ya electrostatic, ndipo apa, tiphunzira mwatsatanetsatane aliyense waiwo. Nawa mitundu itatu ya ESPs:

Plate precipitator: Uwu ndiye mtundu wa precipitator wofunikira kwambiri womwe umakhala ndi mizere ya mawaya owonda ofukula ndi mulu wa mbale zazikulu zachitsulo zosanjikizana zomwe zimayikidwa pamtunda wa 1cm mpaka 18cm motalikirana. Mpweyawo umadutsa m’mbali zopingasa mopingasa ndipo kenako m’mbale zambirimbiri. Kuti ionize tinthu tating'onoting'ono, voteji yoyipa imayikidwa pakati pa waya ndi mbale. Izi particles ionized ndiye amapatutsidwa kwa mbale maziko ntchito electrostatic mphamvu. Pamene tinthu tating'onoting'ono tatolerapo mbale, iwo amachotsedwa mpweya mtsinje.

Dry electrostatic precipitator: Mpweyawu umagwiritsidwa ntchito kusonkhanitsa zowononga ngati phulusa kapena simenti pakauma. Amakhala ndi maelekitirodi omwe particles ionized amapangidwa kuti azidutsamo ndi hopper zomwe zimasonkhanitsidwa particles kunja. Fumbi particles amasonkhanitsidwa kuchokera mtsinje wa mpweya ndi nyundo maelekitirodi.

Dry electrostatic precipitator

Wet electrostatic precipitator: Mpweyawu umagwiritsidwa ntchito kuchotsa utomoni, mafuta, phula, utoto womwe uli wonyowa m'chilengedwe. Amakhala otolera amene mosalekeza sprayed ndi madzi kupanga Kutolere ionized particles ku sludge. Ndiwothandiza kwambiri kuposa ma ESP owuma.

Tubular precipitator: Precipitator iyi ndi gawo limodzi lokhala ndi machubu okhala ndi ma elekitirodi okwera kwambiri omwe amasanjidwa mofananirana kotero kuti akuyenda pa axis yawo. Kapangidwe ka machubu atha kukhala ozungulira kapena mainchesi kapena zisa za uchi za hexagonal wokhala ndi mpweya wopita mmwamba kapena pansi. Mpweya umapangidwa kuti udutse machubu onse. Amapeza ntchito pomwe tinthu zomata ziyenera kuchotsedwa.

Ubwino ndi Kuipa kwake

Ubwino wa electrostatic precipitator:

Kukhazikika kwa ESP ndikokwera.

Itha kugwiritsidwa ntchito kusonkhanitsa zonyansa zonse zowuma komanso zonyowa.

Ili ndi ndalama zochepa zogwirira ntchito.

Kutolera bwino kwa chipangizocho ndikwambiri ngakhale kwa tinthu tating'onoting'ono.

Imatha kuthana ndi ma voliyumu akulu a gasi ndi katundu wolemera wafumbi pazovuta zochepa.

Kuipa kwa electrostatic precipitator:

Sangagwiritsidwe ntchito potulutsa mpweya.

Kufunika kwa malo ndikokwanira.

Capital Investment ndi yayikulu.

Osasinthika kuti asinthe momwe amagwirira ntchito.

Electrostatic Precipitator Applications

Ntchito zochepa zodziwika bwino za electrostatic precipitator zalembedwa pansipa:

Ma ESP a magawo awiri amagwiritsidwa ntchito m'zipinda zamainjini zamasitima popeza bokosi la gear limatulutsa nkhungu yamafuta ophulika. Mafuta osonkhanitsidwa amagwiritsidwanso ntchito mu makina opangira mafuta.

Ma ESP owuma amagwiritsidwa ntchito muzomera zotentha kuyeretsa mpweya mumayendedwe opumira ndi mpweya.

Amapeza ntchito zachipatala zochotsa mabakiteriya ndi bowa.

Amagwiritsidwa ntchito mumchenga wa zirconium pochotsa rutile muzomera.

Amagwiritsidwa ntchito m'mafakitale azitsulo kuti ayeretse kuphulika.
