Iyini i-dust pre-coating works for bag filter housing? Indlela yokugqoka kusengaphambili uthuli?

Izikhwama zokuhlunga uthuli ezigcotshwa ngaphambili noma ukutshala uthuli kusho ukumboza kusengaphambili uthuli losizo lwesisefo ebusweni bezikhwama zokuhlunga uthuli ngaphambi kokuthi amasistimu asebenze ngokujwayelekile lapho efaka izikhwama zokuhlunga ezintsha.
Izinzuzo njengokulandelayo:
1. Lapho isiqoqi sothuli siqala, ikakhulukazi isikhathi sangaphambili, umoya wothuli ungase uhlanganise umswakama ophezulu, futhi uhlanganise amafutha okushisa angaphelele angaphelele, i-coke kawoyela enamathelayo kanye nezinto ze-hydrocarbon nokunye, uma izikhwama zokuhlunga zigcotshwe ngaphambili. , lezi zinto ezimanzi noma ezinamathelayo ngeke zithinte izikhwama zokuhlunga ngokuqondile, ngakho akulula ukuletha izinkinga zokuvimba noma ukugqwala izikhwama zokuhlunga, ngakho-ke kungandisa impilo yesevisi yezikhwama zokuhlunga.
2. Lapho umoya othulini unezinye izinto ze-asidi, njenge-SOx nokunye okungase kudingeke ukuthi kufakwe ezinye izimpushana ze-alkali, njenge-CaO, kodwa ekuqaleni kanzima ukuze uthole okuqukethwe okulungile kwezinto ozozifaka, uma ngaphandle kwe-pre- ungqimba olunamathelayo, lungagqwalisa izikhwama zokuhlunga ngesikhathi sangaphambili.
3. Futhi ungqimba oluvikelayo phezu kobuso bezikhwama zokuhlunga, lungasiza ekwandiseni ukusebenza kahle kokuhlunga kwezikhwama ezintsha zokuhlunga.

Kodwa kanjani ukugqoka kuqala izikhwama zokuhlunga uthuli ngothuli losizo lwesihlungi?
Ngokuvumelana nesipiliyoni sokusebenza isikhathi eside, i-Zonel Filtech inikezwe iziphakamiso ezilandelayo kumakhasimende ethu ukuze zisetshenziswe:
a. Imisebenzi yokumboza yangaphambili idinga ukuhlela ngaphambi kokushisa kubhayela noma ukukhiqizwa, futhi imise amasistimu okuhlanza, ivule ivalve yokungena yothuli.
b. Vula isiphephetha-moya futhi ukhuphule ukugeleza komoya kancane kancane uze uhlangabezane no-70% womklamo, futhi urekhode ukumelana kwamakamelo ahlukene.
c. Faka uthuli losizo lwesihlungi olusuka embotsheni yokufinyelela yepayipi elikhulu.
Njengenjwayelo usayizi wezinhlayiyana zothuli losizo lwesihlungi ungaphansi kwama-micron angama-200, umswakama ungaphansi kuka-1%, ngaphandle kukawoyela, inani lothuli okudingeka lifakwe ngu-350 ~ 450g/m2 ngokuya ngendawo yokuhlunga.
d. Ngaphambi kokufaka uthuli losizo lwesihlungi, qiniseka ukuthi ivolumu yokugeleza komoya ingaphezu kuka-70% wedizayini, futhi uqiniseke ukuthi ivalvu yokudlula ivaliwe, ivalve yokuphakamisa ikulayini. Isiphephetha-moya sidinga ukusebenza cishe imizuzu engu-20 lapho siqeda ukwengeza uthuli lwesihlungi, qiniseka ukuthi uthuli lumbozwe ngaphambili ezikhwameni zokuhlunga ngokulinganayo.
e. Lapho imisebenzi yokumboza iphelile, ukumelana njengenjwayelo kuzokhuphuka cishe ngo-250~300Pa, uma ukumelana kunganyuki njengoba kuceliwe, lokho kusho ukuthi ukusebenza kwehlulekile, kungase kudingeke ukuthi kuphinde izinqubo futhi.
f. Lapho imisebenzi yokumboza iphelile, misa isiphephetha-moya, umhloli aye endlini ehlanzekile yomoya ukuze ahlole ukuthi ingabe kukhona ukuvuza, uma yebo, kungase kudinge ukulungiswa okuthile.
g. Uma ngaphandle kokuvuza kanye nayo yonke idatha ekhonjisiwe evamile, khona-ke ingasebenza ngokuya ngedatha eklanyelwe, ivule uhlelo lokuhlanza futhi lusebenze ngokujwayelekile.
