Zida za thumba la fumbi ndi nsalu kapena zomveka zolukidwa kuchokera ku ulusi wopangira, ulusi wachilengedwe kapena ulusi wagalasi. Nsalu kapena zomverera zimasokedwa m'matumba a cylindrical kapena athyathyathya ngati pakufunika. Malinga ndi katundu wa gasi chitoliro, kusankha zinthu fyuluta oyenera zikhalidwe ntchito. Nthawi zambiri, kutentha kwa gasi kukakhala kotsika kuposa madigiri 120 ndipo zosefera zimafunika kukhala asidi-zosagwira ntchito komanso zolimba, singano ya poliyesitala ndi singano ya poliyesitala-zovala zokhomedwa zimagwiritsidwa ntchito nthawi zambiri; polimbana ndi-gasi wotentha kwambiri (<250℃), graphitized glass fiber cloth is mainly used; in some special cases, carbon fiber filter material is used. It is very important to control the speed of flue gas passing through the filter material (called filtration speed) during the operation of bag filter. The filtration speed is generally 0.5-2m/min, and the efficiency for particles larger than 0.1μm can reach more than 99%, and the equipment resistance loss is about 980-I470Pa.
Chikwama chotolera fumbi chimapangidwa ndi nsalu zosefera -zosamveka, ndipo fumbi{1}lokhala ndi mpweya umasefedwa ndi kusefa kwa nsalu.
Malinga ndi kutentha zakuthupi
1. Chikwama cha kutentha kwanthawi zonse: Chikwama cha kutentha kwanthawi zonse chimapangidwa ndi poliyesitala, polypropylene, acrylic ndi ulusi wina kudzera-zolukidwa ndi nsalu, zokhala ndi mpweya wabwino, zosalala, zokhazikika bwino, zosavuta kuchotsa fumbi ndi zinthu zina zabwino kwambiri. Amagwiritsidwa ntchito pochotsa fumbi m'mabizinesi ambiri ogulitsa ndi kuipitsidwa ndi fumbi komanso kutentha kwabwino kwa gasi ndi madera ena;
2. Chikwama cha kutentha kwapakatikati: Chifukwa chakuti dziko lino likukhudzidwa kwambiri ndi kuteteza chilengedwe, makamaka kukwera msanga kwa makampani opanga ukadaulo wochotsa fumbi m’zaka zaposachedwa, dziko la China layamba kugwiritsa ntchito ulusi wopangidwa kuchokera kunja kuti apange{1}}zida zosefera zogwira ntchito kwambiri zomwe zingagwirizane ndi ntchito zovuta kwambiri komanso kukhala ndi moyo wautali. Pakali pano, zosefera zodziwika bwino zapakati pa kutentha ndizo aramid fiber ndi PPS series fiber, zomwe zimatetezedwa ndi kulowetsedwa, kusalowa madzi, mafuta-kutsimikizira ndi kuletsa-njira zowononga dzimbiri kuti zitheke;
3. Chikwama cha kutentha kwambiri: Chikwama chotentha kwambiri chimakhala chopangidwa ndi P84, fiberglass yowonjezera, ultra-fine glass fiber ndi ulusi wina wolimbana ndi kutentha kwambiri kudzera munsalu ndi{3}}zolukidwa. Ili ndi mawonekedwe a kukhazikika kwamafuta abwino, kusefa kwakukulu komanso moyo wautali wautumiki. Amagwiritsidwa ntchito kwambiri pochotsa fumbi pansi pamikhalidwe yosiyanasiyana yamafuta amtundu wa flue.
Kufotokozera mwatsatanetsatane
Chikwama cha fumbi / thumba la sefa ndi mtima wa fyuluta yachikwama panthawi yogwira ntchito. Nthawi zambiri, thumba la cylindrical pulse filter thumba limayimitsidwa molunjika mu chotolera fumbi. Fumbi-lomwe lili ndi gasi limalowa m'chotolera fumbi kuchokera kumalo olowera mpweya, kumadutsa m'mbale yolondolera phulusa, ndipo tinthu tambirimbiri ta fumbi mu gasiyo timasiyanitsidwa ndi inertia ndikugwera molunjika mu chopondera phulusa. Fumbi-lomwe lili ndi gasi limalowa mugawo losefera la thumba lazosefera la bokosilo. Fumbi lochuluka limagwidwa kunja kwa thumba la fyuluta, ndipo mpweya woyera umalowa mu thumba la fyuluta kudzera muzosefera. Mpweya woyeretsedwa ukalowa m'bokosi lapamwamba kudzera pa doko la thumba la fyuluta, umatulutsidwa kuchokera kumalo opangira mpweya. Khola mkati mwa thumba la fyuluta limagwiritsidwa ntchito kuthandizira thumba la fyuluta kuti thumba la fyuluta lisagwe. Panthawi imodzimodziyo, zimathandiza kuchotsa ndi kugawanso keke yafumbi.
Nsalu ndi kapangidwe ka chikwama cha fumbi ziyenera kuyesetsa kuti-zisefe bwino, kuchotsa fumbi mosavuta komanso kulimba. Kusankhidwa kwa matumba a fumbi ndikofunikira, chifukwa kumakhudza mwachindunji kuchotsedwa kwa fumbi kwa wosonkhanitsa fumbi. Kusankhidwa kwa matumba a fumbi kumachokera pazifukwa zotsatirazi: kutentha kwa mpweya, chinyezi ndi mankhwala, kukula kwa tinthu, fumbi, kuthamanga kwa mphepo, kuthamanga kwa mphepo, njira yoyeretsa fumbi ndi zina.
Zikwama za fumbi nthawi zambiri zimagawidwa m'matumba a fumbi la pulse fumbi, matumba a fumbi la vibration, ndi matumba -opukuta fumbi malinga ndi njira zosiyanasiyana zoyeretsera.
