Kuwerengera njira ya flue gasi voliyumu ya chowotcha kutentha

1. Kusanthula kwa zinthu zoipitsa

1. Kuwerengera kuchuluka kwa gasi wa flue

Kuchuluka kwa mpweya wa flue kumadalira momwe smelting imapangidwira komanso mawonekedwe a fume hood. Pambuyo powerengera kuchuluka kwa mpweya wotulutsa mpweya wa ng’anjo ziwiri zosungunula, zimaphatikizidwa kuwerengera:

Kukula kwa ng’anjo yosungunuka ya 1T yosungunuka ndi yofanana ndi vacuum hood 1 * 1M

Kukula kwa ng’anjo yosungunuka ya 2T yosungunuka ndi yofanana ndi vacuum hood 1.2 * 1.2M

Kuwerengera kuchuluka kwa mpweya woyendetsedwa ndi 1 tani wapakati pafupipafupi msewu: Q=3600*1.4*P*H*V=3600*1.4*4*1.5*0.75=22680M3/H

Kuwerengera kuchuluka kwa mpweya wokonzedwa ndi 2 toni wapakati pafupipafupi msewu: Q=3600*1.4*P*H*V=3600*1.4*4.8*1.5*0.75=27216M3/H

2. Kuthamanga kwa mpweya kwa fan yotulutsa mpweya kumawerengedwa

The pamwamba mawerengedwe a flue mpweya voliyumu amadziwika, flue mpweya voliyumu ya kutentha mankhwala kupatsidwa ulemu ng’anjo kusungunuka ndi 23000 m3/h ndi 27000 m3/h. Kukana kwadongosolo: hood yotulutsa 200Pa + chitoliro 300Pa + thumba fyuluta 1500 Pa + kuthamanga kotsalira 400Pa = 2400Pa.

Chachiwiri, kusanthula koyipa:

1. Utsi ndi fumbi

Malinga ndi mayeso a mafakitale ofanana, utsi woyambirira ndi fumbi ndi 1200-1400 mg/m3, ndipo utsi wakuda ndi 3-5 (kalasi ya Lingelmann).

2. Kutentha kwa mpweya wa flue

Pambuyo pogwidwa ndi hood yotulutsa mpweya, mpweya wa flue wasakanizidwa ndi mpweya wambiri wozizira, ndipo kutentha kwa mpweya wosakanikirana womwe umalowa mu chitoliro ndi wosakwana 100 ° C.

3. Njira ya chithandizo

Chiwembu chokonzekerachi chimatengera: ng’anjo ziwiri zilizonse zosungunula kutentha zimagwiritsa ntchito fyuluta yachikwama, yomwe imapangidwa molingana ndi 2t zitsulo zotulutsa, ndipo ng’anjo ziwiri zotenthetsera kutentha zimatengera njira yopangira utsi wapamwamba kwambiri.

Kutentha kwa ng’anjo yosungunula kutentha kumagwiritsa ntchito ng’anjo yamtundu wa clamp-fume exhaust hood panthawi yosungunuka yokhala ndi utsi wabwino wochotsa utsi ndipo sichikhudzidwa kwambiri ndi kutuluka kwa mpweya wotsatira. Kugwira bwino kwa utsi ndi> 96%. Gasi wa chitoliro atagwidwa ndi chivundikiro cha utsi, amalowa m’chipinda chaching’ono chapaintaneti kutsitsi basi fumbi fumbi wotolera mu payipi, ndiyeno mpweya woyera amakokedwa ndi kutulutsidwa ndi zimakupiza utsi.

3. Kusankhidwa kwa otolera fumbi:

Kutentha kwamankhwala opangira kutentha kusungunula fumbi la utsi kuli ndi kukula kwa tinthu, kukhuthala kwakukulu komanso kumamatira mwamphamvu. Kuti mukwaniritse zosefera izi, DUST64-5 air box pulse fumbi opangidwa ndi Dassman Environmental Protection angagwiritsidwe ntchito pa ng’anjo yamagetsi ya tani 1.

Ng’anjo yosungunuka ya matani 2 imatenga DUST64-6 air box pulse fumbi yopangidwa ndi Dassman Environmental Protection kuti ikwaniritse ntchitoyi.

1. Mapangidwe a pochotsa fumbi (chotolera fumbi)

Kuyeretsa matumba kumabweretsa zovuta. Kugwiritsa ntchito fyuluta yachikwama kumakhala ndi vuto lochotsa fumbi ndipo kumapangitsa thumba kumamatira. Ndikofunikira kugwiritsa ntchito zotsatira zabwino “air box pulse offline fumbi kuyeretsa fumbi lotolera”, ndipo zosefera ndizosavomerezeka ndi mafuta, zopanda madzi komanso zosavuta kuyeretsa singano ya polyester. Kuchotsa fumbi la thumba la fyuluta kumayendetsedwa basi.

Kuchotsa fumbi kwa fyuluta ya thumba ndi 99%, kutulutsa fumbi pambuyo pochotsa fumbi ndi 14mg/m3, ndipo kutulutsa fumbi paola ndi 0.077kg/h. Zizindikiro zomwe zili pamwambazi ndizochepa kusiyana ndi zomwe dziko limatulutsa. Moyo wautumiki wa thumba la fyuluta ndi woposa chaka chimodzi

2. Kugawa mphamvu ndi kulamulira basi

Kukupiza kwakukulu kotulutsa mpweya kumatengera kupanikizika kocheperako kuti ayambe. Zosefera zachikwama zimatengera nthawi kapena kukakamiza kosalekeza kuwongolera ndikuwonetsa ma alarm.
