Kepiye supaya ora bocor tas filter kolektor bledug lan njaga emisi sing sithik?

2024-09-27

Pabrikan sakatas nyaringkudu bocor-bukti amarga nggawe pinholes ing jahitan lan mulane mbukak risiko nambah emisi saka baghouse sak operasi. Nyegah kebocoran njamin supaya baghouses terus-terusan entuk emisi sing sithik. Kita bakal ngrembug babagan carane ndeteksi lan ngatasi bocor ing baghouses ing artikel sing kapisah.


1 Filter Bag Nyegah Bocor

1.1 Proses Leleh Panas

Cairan panas bisa ngatasi masalah burr, benang longgar, lubang jarum lan masalah liyane sing kedadeyan ing jahitan tradisional.tas nyaring, utamane pinholes ing awak tas, efisiensi kira-kira 5 kaping luwih saka jahitan tradisional, lan nduweni kaluwihan malah jahitan lan ikatan sing kuat. Nanging, ora kabeh tas Filter bisa sewn karo proses nyawiji panas, biasane serat siji-lapisan, tas Filter serat termoplastik bisa sewn karo proses nyawiji panas. Figure 1.1 nuduhake diagram skematis saka tas Filter sawise perawatan panas nyawiji. Sawise perawatan panas-nyawiji, ora ana pinholes ing joints saka tas Filter, lan ora ana risiko seng nembus bledug nggoleki liwat pinholes. Mulane, ing kahanan test padha, tas Filter panas-melt nduweni efficiency filtrasi paling dhuwur.

1.2 Proses Coating

Nalika jahitan panas ora bisa digunakake lan jahitan benang digunakake, pinholes mesthi ditinggalake ing tas saringan. Proses lapisan asring digunakake ing industri kanggo nyegah bocor ing tas saringan. Proses lapisan diwiwiti kanthi milih sealant sing cocog kanggo kondisi gas buang sing kompleks. Iki digayuh liwat pendekatan telung cabang: evaluasi laboratorium, uji produksi lan pengalaman teknik. Sawise sealant cocok wis dikenali, peralatan nutupi tas otomatis dipunginaaken kanggo aplikasi lapisan sealant menyang pinholes thread jahitan ing tas. Iki njamin stabilitas lan keseragaman permukaan produk sing dilapisi lan ngoptimalake sealing pinhole. Studies wis ditampilake sing efficiency filtrasi saka tas ditutupi padha karo tas Filter nyawiji panas.

1.3PTFE tape lamination proses kanggo sealing pinholes

Cara tambahan kanggo nyegah bocor yaiku sealing pinholes liwat panggunaan proses laminasi tape PTFE. Senadyan kasunyatan sing tape PTFE minangka bahan tahan panas lan kimia stabil, isih ana kamungkinan sing bisa copot saka landasan nalika wis dileksanakake dening laminasi panas. Sawise tape PTFE wis kebak dibusak, isih ana kamungkinan saka bledug permeating pinholes. Kaya sing digambarake ing Gambar 1.3, iki minangka gambaran skematis saka pinholes ing awaktas saringannderek proses sealing karo tape PTFE.
