Chii chinonzi guruva pre-coating inoshanda yebhegi sefa imba? Nzira yekugadzirira sei guruva?
Dust filter bags pre-coating kana dust seeding zvinoreva pre-coating the filter aid aid pamusoro pemasaga eguruva resefa mabhegi asati ashanda zvakanaka kana akaiswa mabhegi matsva.
Zvakanakira zvinotevera:
1. Kana muunganidzi weguruva atanga, kunyanya nguva yekutanga, mhepo yeguruva inogona kusanganisira yakakwira hunyoro, inosanganisirawo mafuta ekupisa asina kukwana, mafuta anonamira coke pamwe chete nezvinhu zvehydrocarbon uye zvichingodaro, kana mabhegi esefa aine pre-coated. , zvinhu izvi zvakanyorova kana zvinonamira hazvibatanidzi nemabhegi emasefa zvakananga, saka hazvisi nyore kuunza matambudziko ekuvharisa kana kukanganisa mabhegi emasefa, saka anogona kurebesa hupenyu hwebasa remabhegi esefa.
2. Apo mhepo yeguruva ine zvimwe zvinhu zveasidhi, zvakadai seSOx uye zvichingodaro zvingada kuisa mamwe alkali powders, zvakadai seCaO, asi pakutanga zvakaoma kuwana zvakakodzera zvinyorwa zvekuisa, kana pasina pre- coating layer, inogona kukanganisa mabhegi esefa panguva yapfuura.
3. Uyewo chidziviriro chekudzivirira pamusoro pepamusoro pemasaga emasefa, inogona kubatsira kuwedzera kushanda kwesefa yemabhegi matsva.
Asi sei pre-kupfekedza guruva sefa mabhegi neguruva rekubatsira sefa?
Zvinoenderana neakareba zviitiko zvekushanda, Zonel Filtech yakapihwa inotevera mazano kune mutengi wedu kuti ataure:
a. Iwo ekutanga-kuputira anoshanda anofanirwa kuronga pamberi pebhailer kubatidza kana kugadzira, uye kumisa masisitimu ekuchenesa, vhura guruva remhepo inlet valve.
b. Vhura fan uye uwedzere kuyerera kwemhepo zvishoma nezvishoma kusvikira yasangana ne70% yekugadzira, uye rekodha kushorwa kwemakamuri akasiyana.
c. Isa guruva rekubatsira sefa kubva paburi rekupinda repombi huru.
Senguva dzose iyo sefa yekubatsira guruva chidimbu saizi isingasviki mazana maviri micron, hunyoro hwemukati huri pasi pe1%, pasina mafuta, huwandu hweguruva hunoda kuisa 350 ~ 450g/m2 zvinoenderana nenzvimbo yekusefa.
d. Usati waisa guruva rekubatsira sefa, ita shuwa kuti vhoriyamu yekuyerera kwemhepo inopfuura 70% yedhizaini, uye ita shuwa kuti bypass valve yakavharwa, yekusimudza valve iri pamutsetse. Iyo fan inofanirwa kushanda ingangoita maminetsi makumi maviri kana yapedza iyo sefa yekubatsira guruva ichiwedzera, ita shuwa kuti guruva rakafanoputirwa pamabhegi esefa zvakaenzana.
e. Kana iyo pre-coating inoshanda yapera, kushorwa senguva dzose kuchawedzera nezve 250 ~ 300Pa, kana kuramba kukasawedzerwa sekukumbirwa, zvinoreva kuti kushanda kwakakundikana, kungangoda kudzokorora maitiro zvakare.
f. Kana iyo pre-coating ichishanda, misa feni, inspector enda kune yakachena mhepo imba kuti atarise kana paine kuvuza, kana hongu, ingangoda kugadziriswa.
g. Kana pasina kuvuza uye data rese rinoratidzwa zvakajairika, saka inogona kushanda zvinoenderana neyakagadzirirwa data, vhura iyo yekutsvaira system uye inoshanda zvakajairwa.
