Yintoni i-Electrostatic Precipitator?

Ushishino yinxalenye ebalulekileyo yenkqubo yethu yezoqoqosho, yaye abaninzi bakholelwa ukuba lilungelo labo ukunyamezela imisi yomsi yomzi-mveliso efunxa umoya. Kodwa ababaninzi bayazi ukuba itekhnoloji inesisombululo esihle kakhulu kule nto ngaphezulu kwenkulungwane kwimilo ye-electrostatic precipitators. Ezi zinto zinciphisa kakhulu ungcoliseko kwaye zinceda ekuphuculeni okusingqongileyo.

Yintoni i-Electrostatic Precipitator?

I-electrostatic precipitator (ESP) ichazwa njengesixhobo sokuhluza esisetyenziselwa ukususa amasuntswana amahle afana nomsi kunye nothuli olucolekileyo olusuka kwirhasi ehambayo. Sesona sixhobo sixhaphakileyo sokulawula ukungcoliseka komoya. Zisetyenziswa kumashishini afana nezityalo zentsimbi, kunye nezityalo zamandla ashushu.

Ngo-1907, unjingalwazi wekhemistri uFrederick Gardner Cottrell unelungelo elilodwa lomenzi we-precipitator yokuqala ye-electrostatic esetyenziselwa ukuqokelela inkungu ye-sulfuric acid kunye ne-lead oxide imisi ephuma kwimisebenzi eyahlukeneyo yokwenza kunye nokunyibilikisa.

Umzobo we-electrostatic precipitator

Umgaqo-siseko wokuSebenza we-Electrostatic Precipitator

Umgaqo osebenzayo we-electrostatic precipitator ulula ngokuphakathi. Iqukethe iiseti ezimbini zee-electrode: ezilungileyo kunye ne-negative. I-electrodes engalunganga ikwimo ye-wire mesh, kwaye i-electrodes ephilileyo ngamacwecwe. Ezi electrode zibekwe ngokuthe nkqo kwaye ziyatshintshana.

umgaqo wokusebenza we-electrostatic precipitator

Amasuntswana athwalwa yirhasi anjengothuthu afakwa i-ioni yi-electrode yokukhutshwa kombane ophezulu ngesiphumo se-corona. La masuntswana afakwe ionisi kwintlawulo embi kwaye atsalwa kwiipleyiti zabaqokeleli ezihlawulwe kakuhle.

Itheminali engalunganga yomthombo wombane ophezulu we-DC isetyenziselwa ukudibanisa i-electrode engalunganga, kwaye i-terminal echanekileyo yomthombo we-DC isetyenziselwa ukudibanisa iipleyiti ezilungileyo. Ukwenza i-ionize iphakathi phakathi kwe-electrode engalunganga kunye ne-positive electrode, umgama othile ugcinwa phakathi kwe-electrode efanelekileyo, engalunganga kunye nomthombo we-DC okhokelela kwi-gradient yombane ophezulu.

Isiphakathi esisetyenziswa phakathi kwee-electrode ezimbini ngumoya. Kusenokubakho ukukhutshwa kwe-corona ejikeleze iintonga ze-electrode okanye umnatha wocingo ngenxa yokuchasa okuphezulu kweentlawulo ezingalunganga. Yonke inkqubo ifakwe kwisitya sesinyithi esine-inlet ye-flue gases kunye ne-outlet yeegesi ezihluziweyo. Kukho ininzi yee-electron zamahhala njengoko i-electrodes i-ionized, edibanisa namasuntswana othuli lwegesi, okwenza ukuba bahlawuliswe kakubi. La masuntswana ukuya electrode positive kwaye awe ngenxaamandla omxhuzulane. Irhasi ye-flue ikhululekile kumasuntswana othuli njengoko ihamba nge-electrostatic precipitator kwaye ikhutshwe emoyeni ngetshimini.

Iintlobo ze-Electrostatic Precipitator

Kukho iintlobo ezahlukeneyo ze-electrostatic, kwaye apha, siza kufunda nganye kuzo ngokweenkcukacha. Ezi ntlobo zintathu zee-ESPs zilandelayo:

I-Plate precipitator: Olu lolona hlobo lusisiseko lwe-precipitator oluqulathe imiqolo yeengcingo ezibhityileyo ezithe nkqo kunye ne-stack yeepleyiti ezinkulu zesinyithi ezicwangciswe ngokuthe nkqo ezibekwe kumgama we-1cm ukuya kwi-18cm ukuqelelana. Umjelo womoya ugqithiswa ngokuthe tye kwiipleyiti ezithe nkqo kwaye emva koko kugqithiswa kuluhlu olukhulu lwamacwecwe. Ukuze i-ionize iinqununu, i-voltage engalunganga isetyenziswe phakathi kwecingo kunye neplate. La masuntswana e-ionized emva koko ajikiselwe kwiipleyiti ezisekelwe phantsi kusetyenziswa amandla e-electrostatic. Njengoko amasuntswana aqokelelwa kwipleyiti yokuqokelela, ayasuswa kumlambo womoya.

I-Dry electrostatic precipitator: Le precipitator isetyenziselwa ukuqokelela izinto ezingcolileyo ezifana nothuthu okanye i-samente kwindawo eyomileyo. Iqukethe i-electrodes apho iinqununu ze-ionized zenziwa ukuba zihambe kunye ne-hopper apho iinqununu eziqokelelweyo zikhutshwa khona. Amasuntswana othuli aqokelelwa kumlambo womoya ngokubethelela i-electrodes.

I-electrostatic precipitator eyomileyo

I-electrostatic precipitator emanzi: Le precipitator isetyenziselwa ukususa i-resin, i-oyile, itela, ipeyinti emanzi ngokwendalo. Iqukethe abaqokeleli abahlanjululwa ngokuqhubekayo ngamanzi okwenza ukuqokelela kweengqungquthela ze-ionized kwi-sludge. Zisebenza kakuhle kunee-ESP ezomileyo.

I-Tubular precipitator: Le precipitator yiyunithi yenqanaba elinye elibandakanya iityhubhu ezinama-electrode ombane aphezulu alungelelaniswe ngokuhambelanayo ukuze asebenze kwi-axis yawo. Ulungelelwaniso lwetyhubhu lunokuba setyhula okanye isikwere okanye ikhekheba lobusi olunehexagonal enegesi equkuqela ibheka phezulu okanye ezantsi. Irhasi yenziwa ukuba idlule kuzo zonke iityhubhu. Bafumana izicelo apho amasuntswana ancangathi kufuneka asuswe.
