Isikhokelo esiBalulekileyo kwi-Electrostatic Precipitators: Ukuqonda ukusebenza kwabo, iiNzuzo, iintlobo, kunye nezicelo zoShishino

Iiprecipitators ze-Electrostatic, eziqhelekileyo ezifinyeziweyo njenge-ESPs, zizixhobo zokulawula ukungcoliseka komoya eziphucukileyo ezisusa ngokufanelekileyo i-particle, efana nothuli kunye namasuntswana omsi, kwiigesi eziphuma kwimizi-mveliso. Ukusebenza nokuthembeka kwabo kubenze baba yintsika kumashishini ahlukeneyo, kuquka ukwenziwa kombane, ukwenziwa kwentsimbi, ukwenziwa kwesamente, nokunye. Eli nqaku ligocagoca malunga nokusebenza, iingenelo, iintlobo, kunye nokusetyenziswa kwe-electrostatic precipitators.

Umthetho-siseko osisiseko emva kwee-ESPs ngumtsalane we-electrostatic phakathi kwamasuntswana atshajisiweyo kunye nemigangatho echajiwe ngokuchasayo. Inkqubo inokwahlulwa ngokubanzi ibe ngamanqanaba amane:

1.Ukutshaja: Njengoko i-exhaust gas ingena kwi-ESP, idlula kuluhlu lwe-electrodes yokukhupha (ngokuqhelekileyo iingcingo zetsimbi ezibukhali okanye iipleyiti) ezihlawulwe ngombane ngombane ophezulu. Oku kubangela i-ionization yomoya ojikelezayo, ukuvelisa ifu le-ion elichasayo elichanekileyo nelibi. Ezi ion zingqubana nentwana yerhasi, inika umrhumo wombane kumasuntswana.

2.Ukutshaja kweParticle: Amasuntswana atshajiweyo (ngoku abizwa ngokuba zii-ion okanye amasuntswana e-ion-bound) aphuma ngombane kwaye atsaleleke kwindawo enechaji encomekayo okanye engachajiyo, ngokuxhomekeke kwi-polarity yazo.

3.Ukuqokelelwa: Amasuntswana ahlawuliweyo afudukela kwaye afakwe kwi-electrode yokuqokelela (ngokuqhelekileyo inkulu, iipleyiti zetsimbi ezisicaba), ezigcinwe kwindawo engaphantsi kodwa echaseneyo kunye ne-electrodes ekhutshwayo. Njengoko amasuntswana aqokelelana kwiipleyiti zokuqokelela, enza umaleko wothuli.

I-4.Ukucoca: Ukugcina ukusebenza ngokufanelekileyo, iiplate zokuqokelela kufuneka zihlanjululwe ngezikhathi ezithile ukuze zisuse uthuli oluqokelelweyo. Oku kuphunyezwa ngeendlela ezahlukeneyo, kubandakanywa i-rapping (ukungcangcazela iipleyiti ukukhupha uthuli), ukutshiza ngamanzi, okanye ukudibanisa zombini. Uthuli olususiweyo ke luyaqokelelwa luze lulahlwe ngokufanelekileyo.

Inkqubo ye-electrostatic precipitator

Izinto ezilungileyo zekwayelectrostaticpabamkeli

Ubuchule obuphezulu: Ii-ESPs zinokufikelela kwimpumelelo yokususa amasuntswana angaphezu kwe-99%, nto leyo ezenza zibe zilungele imimiselo engqongqo yokusingqongileyo.

I-Versatility: Banokusingatha uluhlu olubanzi lwee-particle size kunye nokugxininiswa, ukusuka kwiincinci ze-submicron ukuya kwi-coarse dust.

Ukwehla koxinzelelo oluphantsi: Uyilo lwe-ESPs lunciphisa ukuchasana nokuhamba kwegesi, ukunciphisa ukusetyenziswa kwamandla kunye neendleko zokusebenza.

I-Scalability: Ii-ESPs zinokuyilwa ukuba zihambelane nezakhono ezahlukeneyo, ukusuka kwizicelo ezincinci ukuya kwimizi-mveliso emikhulu.

Ubomi obude: Ngokugcinwa okufanelekileyo, ii-ESPs zinokusebenza amashumi eminyaka, zibonelela ngesisombululo esineendleko eziphezulu kwixesha elide.

Iindidi ze-Electrostatic Precipitators

I-Plate-Type ESPs: Olona hlobo luxhaphakileyo, oluneepleyiti ezihambelanayo ezilungiselelwe ngokuthe nkqo okanye ngokuthe tye njengokuqokelela i-electrode.

I-Tube-Type ESPs: Isebenzisa iityhubhu zentsimbi endaweni yeepleyiti njengokuqokelela i-electrode, ehlala ifumaneka kwizicelo ezinobushushu obuphezulu okanye iigesi ezidliwayo.

Ii-ESP ezimanzi: Dibanisa isitshizi samanzi kuzo zombini ezikhuthaza ukuqokelelwa kwamasuntswana kunye nokuququzelela ukususwa kothuli, okusebenzayo ngakumbi kumasuntswana ancangathi okanye akhule ngehygroscopic.

Usetyenziso

Ukuveliswa koMbane: Amaziko ombane asebenzisa amalahle asebenzisa ii-ESPs ukususa uthuthu lwempukane kunye nenkungu ye-sulfuric acid kwiigesi zombhobho.

Ukucutshungulwa kwesinyithi: Imizi-mveliso yentsimbi kunye ne-aluminium ixhomekeke kwii-ESPs ukulawula ukukhutshwa kweziko, iziguquli, kunye nee-rolling Mills.

I-Cement Manufacturing: Ngexesha lokuvelisa i-clinker, i-ESPs ibamba uthuli kunye nezinye iinqununu ezenziwe kwiinkqubo ze-kiln kunye ne-mill.

Ukutshiswa kweNkunkuma: Isetyenziselwa ukucoca igesi yombhobho evela kumasipala nakwizitshisi zenkunkuma eziyingozi.

Ukwenziwa kweMichiza: Ekuveliseni imichiza efana ne-asidi ye-sulfuric, ii-ESPs zinceda ukugcina imijelo ecocekileyo yokukhupha.

Ukuqukumbela, i-electrostatic precipitators zizixhobo eziyimfuneko zokunciphisa ungcoliseko lomoya kumashishini ahlukeneyo. Ukusebenza kwawo okuphezulu, ukuguquguquka, kunye nokusebenza kakuhle kweendleko kubenza ukhetho olukhethwayo lokulawula ukukhutshwa kwezinto ezikhutshwayo kunye nokukhusela impilo yoluntu kunye nokusingqongileyo. Njengoko iteknoloji iqhubela phambili, ii-ESPs ziyaqhubeka nokuvela, zibandakanya uyilo olutsha kunye nemathiriyeli ukuhlangabezana neemfuno ezihlala zisanda zemithetho yendalo esingqongileyo kunye neenkqubo zoshishino.
