WesternFlag - Gulu la Zipangizo Zowumitsa

Ⅰ. Kuyanika kwa convection

Pazida zowumitsira, chowumitsira chodziwika bwino kwambiri ndi chowumitsira kutentha kwa convection. Mwachitsanzo,kutentha mpweya kuyanika, mpweya wotentha ndi kukhudzana kwa zinthu zosinthira kutentha kuti zisungunuke chinyezi. Mitundu yodziwika bwino ya zida zowumitsira ma convection ndi zowumitsira mpweya, monga zowumitsira bedi za fluidized, zowumitsira ma flash, zowumitsira mpweya, zowumitsira mpweya, zowumitsira mpweya, zowumitsira mpweya, zowumitsira mpweya, zowumitsa, zowumitsira, zowumitsira zofanana,zowumitsa rotaryndi zina zotero.

Pakugwiritsa ntchito, pali makina amodzi omwe amagwiritsidwa ntchito ndi makina ophatikizana omwe amagwiritsidwa ntchito. Chowumitsira mpweya, chowumitsira bedi, chowumitsira utoto, ndi zina zotere zimagwiritsa ntchito mpweya wotentha ngati gwero la kutentha, ndipo kusamutsidwa kwazinthu kumamalizidwa ndikuwumitsa, ndipo zowumitsira zotere zimadziwika kwambiri ndi kusakhalapo kwa magawo opatsirana.

Kuyanika ufa, granule ndi flake zipangizo, njira wamba ndi ntchito mpweya wotentha kapena gasi otaya pamwamba pa granule, ndi kusamutsa kutentha kwa zinthu kudzera airflow kuti asamasanduke nthunzi madzi. Mpweya wamadzi womwe umatuluka umapita mumlengalenga ndikuchotsedwa. Makanema owumitsa omwe amagwiritsidwa ntchito kwambiri poyanika makina opangira ma convection ndi mpweya, mpweya wa inert, mpweya woyaka mwachindunji kapena nthunzi yotentha kwambiri.

Njirayi imapangitsa kuti mpweya wotentha ukhale wogwirizana ndi zinthuzo ndikuchotsa chinyezi pamene ukutentha. Chofunikira ndikuwongolera malo olumikizana pakati pa zinthu ndi mpweya wotentha kuti mupewe kupotoza kwa mpweya wotentha. Kutentha kwa zinthu panthawi yowuma ya isokinetic kumakhala kofanana ndi kutentha kwa babu yonyowa kwa mpweya wotentha, kotero kugwiritsa ntchito mpweya wotentha kwambiri kumatha kuumanso zinthu zomwe sizimva kutentha. Njira yowumitsa iyi imakhala ndi kuyanika kwakukulu komanso kutsika mtengo kwa zida, koma kutentha kwamafuta ndikotsika, izi ndizomwe zimachitika pazida zingapo zowumitsa zowongolera:

(1) Chowumitsira mpweya

Pangani pamwamba pa chipika kapena zinthu zomwe zakhala zokhazikika kukhudzana ndi mpweya wotentha. Kuwumitsa ndi kutsika, koma mawonekedwe a ntchito ndi ambiri.

(2)Zowumitsira pabedi zamadzimadzi

Lolani kuti mpweya wotentha ukhale wofanana kuchokera pansi pa ufa ndi zipangizo za granular ndikupangitsa kuti ziziyenda, kotero kuti zipangizozo zidzasakanizidwa mwamphamvu ndikubalalika. Kuchuluka kwa kuyanika ndikwambiri.

(3) Chowumitsira mpweya

Njirayi imapangitsa ufawo kumwazikana mu mpweya wotentha wotentha kwambiri ndikutumiza zinthuzo ndikuwumitsa. Chitsanzochi chimakhala ndi nthawi yochepa yowumitsa ndipo ndi yoyenera kugwiritsira ntchito zipangizo zambiri. Ngati zinthu mu chowumitsira musanagwiritse ntchito makina njira kuchotsa ambiri madzi asanalowe mpweya choumitsira ndi ndalama zambiri.

(4) Chowumitsira utsi

Kuti njira kapena slurry zipangizo mu mkulu kutentha kutentha mpweya atomization, m'malovu kugwa nthawi yomweyo kuyanika. Njira iyi yowumitsa nthawi ndi yochepa, yoyenera kupanga misala, yamankhwala, nkhonya, kuyanika utoto.

(5) Chowumitsira masilinda ozungulira

Pangani ufa, chipika, slurry zipangizo kudzera m'ng'oma mozungulira kukhudzana ndi mpweya wotentha. Njirayi ndi yoyenera kupanga zambiri. Pambuyo poumitsa matope amatha kutulutsidwa ngati zinthu za granular, kuyanika kwa mchere wambiri kumagwiritsidwa ntchito motere.

(6) chowumitsira moto

Nkhaniyi imayendetsedwa ndi tsamba lothamanga kwambiri lothamanga kwambiri, kotero kuti limabalalika mu kayendetsedwe ka kayendedwe ka mpweya wa gasi panthawi imodzimodziyo kuyanika. Nthawi zambiri ntchito pa kuyanika sing'anga-voliyumu zipangizo, makamaka ntchito kuyanika phala zipangizo.

Ⅱ. Kuyanika kochititsa

Kuyanika kwa conduction kumasinthasintha kwambiri ndi tinthu tonyowa, ndipo zida zowumitsa zowongolera zimakhala ndi kutentha kwambiri. Mpweya wamadzi wosungunuka umachotsedwa ndi vacuum kapena kutayidwa ndi mpweya, womwe ndiye chonyamulira chachikulu cha chinyezi, ndipo kugwiritsa ntchito vacuum kumalimbikitsidwa pazida zomwe sizimva kutentha. Pazida zowumitsira ma conduction, paddle dryer imagwiritsidwa ntchito poyanika zida za phala. Zowumitsira zozungulira zokhala ndi machubu oyenda mkati apangidwa tsopano, monga chowumitsira bedi chomiza madzi kuti awumitse ma polima osamva kutentha kapena ma pellets amafuta, omwe ndi gawo limodzi mwa magawo atatu a kukula kwake kwa chowumitsira bedi chamadzimadzi.

Kuyanika kwa vacuum ndi njira yochepetsera kutentha komanso kuyanika kwapang'onopang'ono potenthetsa zinthuzo pansi pa vacuum kuti chinyonthocho chifalikire mkati, chisasunthike mkati, chisasunthike, ndikusungunuke pamwamba. Ili ndi ubwino wa kutentha kochepa, kutentha kwabwino kwa antioxidant, yunifolomu yazinthu zowonongeka, khalidwe lapamwamba ndi ntchito. Kuyanika kwa vacuum ndikokwera mtengo, ndipo kuyanika kwa vacuum kumalimbikitsidwa pokhapokha ngati zinthuzo ziyenera kuumitsidwa ndi kutentha kochepa kapena kusowa kwa okosijeni, kapena zikawonongeka ndi kuyanika potentha sing'anga ndi kutentha kwambiri. Kuti pakhale mpweya wabwino, ntchito yotentha kwambiri imagwiritsidwa ntchito kuti mpweya wotuluka uchepe komanso kuchuluka kwa zida zitha kuchepetsedwa. Pa ntchito yowumitsa kutentha pang'ono, kutentha koyenera kwa zinyalala kapena chotengera cha solar kumatha kusankhidwa ngati gwero la kutentha, koma kuchuluka kwa chowumitsira kumakhala kwakukulu.

Ⅲ. Kuphatikiza kuyanika

Kugwiritsa ntchito njira zosiyanasiyana zowumitsa, kuphatikiza mfundo zowumitsa zosiyanasiyana, kumatha kusewera mphamvu zawo ndikuwongolera zofooka zawo pazida zowumitsa. Mwachitsanzo, njira yowumitsira mwachindunji ndi njira yowunitsira molunjika ndikugwiritsa ntchito njira yowumitsa yosalunjika kuti muumitse kutentha kwakukulu komwe kumafunikira. Mwanjira iyi, kuchuluka kwa kuyanika kumatha kupitilizidwa, ndipo njira yowumitsa yachindunji komanso yosalunjika ndi zida zowumitsa zokhala ndi zida zazing'ono komanso kutentha kwambiri kumatha kupezeka.

Zipangizo zowumitsira zophatikizika zimagwiritsidwanso ntchito mochulukira, monga chowumitsira chowumitsira ndi kugwedeza kwamadzi owumitsira bedi, chowumitsira chowumitsa ndi chowumitsira chowumitsira pabedi, chowumitsira chozungulira, chowumitsira chophatikizira, chowumitsira mpweya ndi chowumitsira bedi cha fluidized. Kuphatikiza kwa cholinga ndikupeza chinyezi chochepa, monga chowumitsira kutsitsi chimodzi chingapezeke 1% -3% chinyezi cha mankhwala, monga chinyezi cha 0.3% kapena kuchepera, kutentha kwa mpweya nthawi zambiri kumafunika 120 ℃ kapena zambiri, kutaya mphamvu kutentha ndi lalikulu kwambiri. Mofananamo, ngati pali zofunika zina chinyezi, chinyezi okwana zosakwana 0.1%, kutentha utsi chofunika pamwamba 130 ℃. Pofuna kupulumutsa mphamvu matenthedwe, mu kamangidwe ka ntchito ambiri 90 ℃ utsi kutentha choumitsira kutsitsi, kuti chinyezi 2%, kutentha kuchira kwaiye 60 ℃ mpweya wotentha angagwiritsidwe ntchito mndandanda kwa kuyanika. bedi yopingasa fluidized, mapeto a chinyezi akhoza kufika 0.1% kapena zochepa, ndi mphamvu matenthedwe akhoza kupulumutsa 20%.

Nthawi zina, mankhwalawo akawumitsidwa kapena kukonzedwa, kutentha kwa chinthu kumapangitsa kusintha, kapena mawonekedwe a chinthucho amasintha. Mwachionekere, mu nkhani iyi ntchito awiri kapena kuposa awiri osiyana mitundu ya kuyanika zida kuphatikiza kuyanika ndi zabwino.

Ndiye, momwe mungasankhire zowumitsira zoyenera za zida zanu? Takulandirani kuti mulankhule!
