SIR Ndi yosiyana, chifukwa ma frequency ake amagetsi ndi 500 nthawi yamagetsi wamba. Kutulutsa kwa spark kumachitika, kusinthasintha kwake kumakhala kochepa, ndipo kumatha kutulutsa pafupifupi kutulutsa kwa HVDC. Chifukwa chake, SIR Itha kupereka zambiri zamakono kumunda wamagetsi. Opaleshoni ya precipitators electrostatic angapo limasonyeza kuti linanena bungwe panopa wa ambiri SIR Kuposa 2 nthawi ya ochiritsira T / R magetsi, kotero dzuwa la precipitator electrostatic adzakhala kwambiri bwino.
The siteji yachitatu: kuyambira mankhwala utsi mpweya. Mukhozanso kuwonjezera magawo atatu a kuchotsa fumbi pambuyo kuchotsa electrostatic fumbi, monga kugwiritsa ntchito nsalu thumba fumbi kuchotsa, akhoza bwinobwino kuchotsa tinthu tating'ono ting'ono fumbi, kusintha kuyeretsedwa kwenikweni, kuti akwaniritse cholinga cha kuipitsidwa-free. mpweya.
Ichi ndi ndimeGD mtundu electrostatic precipitator luso anayambitsa mu Japan choyambirira electrostatic precipitator luso, kudzera chimbudzi ndi mayamwidwe zinachitikira bwino makampani zoweta, anapanga mndandanda wa GD mtundu electrostatic precipitator, chimagwiritsidwa ntchito zitsulo, smelting makampani.
Kuwonjezera makhalidwe a mitundu ina ya precipitators electrostatic ndi kukana otsika, otsika mphamvu mowa ndi dzuwa mkulu, ndi GD mndandanda ali mfundo zotsatirazi:
◆ Kapangidwe kake kagawidwe ka mpweya kakulowetsa mpweya ndi kapangidwe kake.
◆ Pali ma electrode atatu m'munda wamagetsi (electrode yotulutsa, electrode yosonkhanitsa fumbi, electrode yothandizira), yomwe imatha kusintha kusintha kwa polar ya gawo lamagetsi kuti isinthe gawo lamagetsi, kuti igwirizane ndi mankhwala a fumbi ndi makhalidwe osiyanasiyana komanso kukwaniritsa chiyeretso.
◆ zoipa - zabwino mizati ufulu kuyimitsidwa.
◆ Waya wa Corona: Ziribe kanthu kuti waya wa corona ndi wautali bwanji, umapangidwa ndi chitoliro chachitsulo, ndipo palibe cholumikizira cha bawuti pakati, kotero palibe kulephera kuthyola waya.agraph Zofunikira pakuyika
◆ Yang'anani ndikutsimikizirani kuvomereza pansi pa precipitator musanayambe kukhazikitsa. Kukhazikitsa zigawo zikuluzikulu za precipitator electrostatic malinga ndi zofunika za unsembe malangizo a electrostatic precipitator ndi zojambula zojambula. Kudziwa chapakati unsembe m'munsi mwa precipitator electrostatic malinga ndi chitsimikiziro ndi kuvomereza maziko, ndi kutumikira monga maziko unsembe wa anode ndi cathode dongosolo.
◆ Yang'anani kusalala, mtunda wamtunda ndi zolakwika za diagonal za ndege yoyambira
◆ Yang'anani zigawo zipolopolo, konzani mapindikidwe mayendedwe, ndi kukhazikitsa iwo wosanjikiza ndi wosanjikiza kuchokera pansi mpaka pamwamba, monga gulu thandizo - pansi mtengo (anaika phulusa hopper ndi magetsi munda nsanja mkati pambuyo podutsa anayendera) - ndime ndi mbali. khoma gulu - pamwamba mtengo - cholowera ndi potulukira (kuphatikiza mbale yogawa ndi mbale) - anode ndi cathode dongosolo - pamwamba chivundikiro mbale - mkulu voteji magetsi ndi zipangizo zina. Makwerero, mapulatifomu, ndi njanji zitha kukhazikitsidwa mosanjikiza ndi wosanjikiza mumayendedwe oyika. Chigawo chilichonse chikayikidwa, fufuzani ndikulemba molingana ndi zofunikira za Kuyika kwa Electrostatic Fumbi Collector ndi zojambula zojambula: mwachitsanzo, mutatha kuyika flatness, diagonal, mtunda wa mzati, verticality, ndi mtunda wamtunda, fufuzani kulimba kwa mpweya. wa zida, kukonza kuwotcherera kwa mbali zikusowa, fufuzani ndi kukonza kuwotcherera akusowa mbali.
Electrostatic precipitator lagawidwa mu: molingana ndi malangizo a mpweya otaya anawagawa ofukula ndi yopingasa, malinga ndi mpweya mzati mtundu anawagawa mbale ndi chubu mtundu, malinga ndi kuchotsa njira fumbi pa mbale mpweya anawagawa youma. chonyowa mtundu.
